Worm wheel gearbox

The worm wheel gearbox transmission is composed of a worm wheel gearbox and a worm wheel gearbox wheel. In the past, the domestic worm wheel gearbox gear was basically 1 to 3 heads. Now many imported worm wheel gearbox s have 4 heads and 6 heads. A transmission that transmits motion and power between two axes that are interlaced in space. The angle between the two axes can be any value, and is usually 90°. This type of transmission is widely used in machine tools, automobiles, instruments, crane transport machinery, metallurgical machinery and other machines due to its compact structure, large transmission ratio, stable transmission and reliable self-locking under certain conditions.

WP worm wheel gearbox is developed on the basis of wd worm wheel gearbox . The worm wheel gearbox is made of 45# high-quality steel by heat treatment. The worm wheel gearbox
wheel is made of tin bronze. The wear resistance is good, especially in the bearing capacity. It is mainly used for the reduction transmission
of various mechanical equipment such as plastics, metallurgy, beverages, mining, lifting and transportation, chemical construction and so on.
The worm wheel gearbox is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the
motor (motor) to the required number of revolutions and obtain a mechanism with a large torque. In the mechanism for transmitting power
and motion, the range of applications of the worm wheel gearbox is quite extensive. It can be seen in the transmission system of various types of machinery,
from ships, cars, locomotives, heavy machinery for construction, processing equipment and automatic production equipment used in the machinery
industry, to household appliances that are common in daily life. , clocks, etc. Its application can be seen from the transmission of large power,
to small loads, accurate angular transmission can be seen in the application of the worm wheel gearbox , and in industrial applications, the worm wheel gearbox has the
function of deceleration and increased torque. Therefore, it is widely used in speed and torque conversion equipment.

The main functions of the worm wheel gearbox are: 1. Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output and the
reduction ratio, but it should be noted that the rated torque of the worm wheel gearbox cannot be exceeded. 2. Deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio. You can see that the
general motor has an inertia value.
Note for worm wheel gearbox : When installing the worm wheel gearbox , it must be firmly installed on the machine, and it should not be loose. In this process, it must be
confirmed that the steering of the worm wheel gearbox is correct before the installation operation can be performed intermittently. The worm wheel gearbox can not
be placed for too long, more than 3 to 6 months, and the oil seal is not immersed in the lubricating oil, it is recommended that the worm wheel gearbox
user replace the oil seal. Please follow the speed worm wheel gearbox 's code of use. The standard working environment temperature is -5 to 10 degrees.
If this value is exceeded, please contact the manufacturer. The worm wheel gearbox is usually used with a geared motor or motor, so ventilation must be
installed to improve heat dissipation and keep it running. When it is installed, it is necessary to check the lubricating oil level first, and it is not
necessary to increase the load immediately. It is recommended to increase it gradually. It is recommended to install a protective device
around the worm wheel gearbox .

First, WP cast iron worm wheel gearbox overview:     WP worm wheel gearbox is developed on the basis of wd worm wheel gearbox . The worm wheel gearbox is made of 45# high-quality steel by heat treatment. The worm wheel gearbox
wheel is made of tin bronze. The wear resistance is good, especially in the bearing capacity. It is mainly used for the reduction transmission
of various mechanical equipment such as plastics, metallurgy, beverages, mining, lifting and transportation, and chemical construction.
Second, WP cast iron worm wheel gearbox features:     1. The transmission is stable, the vibration, impact and noise are small, the reduction ratio is large, the versatility is wide, and it can be
used with various mechanical equipments.     2. It can obtain a large transmission ratio with single-stage transmission, and has a compact structure. Most models have better self-locking
performance, and can save braking devices for mechanical equipment with braking requirements.     3. The meshing friction loss of the worm wheel gearbox screw tooth and the worm wheel gearbox gear tooth surface is large, so the transmission efficiency is lower than
the gear, easy to heat and high temperature.     4. Higher requirements for lubrication and cooling.     5, good interoperability, worm wheel gearbox gears are manufactured according to national standards, bearings, oil seals, etc. are used standard parts.     6, the box type has a basic type (the box is a vertical or horizontal structure with a foot plate) and a universal type (the box is a rectangular
parallelepiped, with multiple fixed holes, no bottom plate or another bottom) Various types of structure such as foot board)     7. There are two basic types of input shaft connection (single input shaft and double input shaft) and two types of motor flanges.     8. The output and input shafts have the input shaft at the bottom and the top; the output shaft is up and down; the input shaft is up and
down.     9. Two or three worm wheel gearbox s can be used to form a multi-stage worm wheel gearbox to obtain a great gear ratio.

Third, WP cast iron worm wheel gearbox working conditions:     1. The worm wheel gearbox speed of the worm wheel gearbox cannot exceed 1500r/min.     2. The working environment temperature is -40 °C - +40 °C. When the working environment temperature is lower than 0 °C, the lubricating
oil must be heated to above 0 °C before starting. When the working environment temperature is higher than 40 °C, cooling measures must be
taken.     3. The worm wheel gearbox can be rotated in the positive and negative directions.

Fourth, note:     1. The worm wheel gearbox gear shaft can never be used as an input shaft.     2. The supporting motor (ie power) cannot exceed the value specified on the label. 3. If the user wants to change the direction of the input shaft, the lower end cover of the lower shaft can be removed, the worm wheel gearbox shaft can be
taken out and the 180 can be adjusted. Just load it. Do not hard knock when installed, slowly drive the two shafts to make them engage. The noise of the turbine worm wheel gearbox is mostly related to the lack of precision, while the overheating is related to the small gap. Usually these two
problems come back at the same time, indicating that the precision of the manufacturing is not enough. The solution is to adjust the position
of the worm wheel gearbox shaft through the two ends. Adding or subtracting the gasket adjustment, the noise as long as it is not higher than 70 decibels
is normal, and the running noise will be much lower. Good lubrication will also improve noise and overheating. Generally, the lubricating oil
will not pass through 1/3 of the worm wheel gearbox .
A suitable and more affordable way to use a worm wheel gearbox is to use a custom motor drive that includes a worm wheel gearbox and motor.
On the one hand, the worm wheel gearbox has the characteristics of mechanical precision, compact design, durability, low maintenance time
and long service life; on the other hand, in the absence of other mechanical devices, relying on clutches, shafts and motors, a relatively
simple drive solution can be realized. Some linear or rotary motion.

which avoids the high failure rate of the mechanical lifting mechanism due to the impact and greatly improves the production efficiency. 6. Significant energy saving and obvious economic benefits are of great significance for reducing production costs and improving product
competitiveness.
What is the self-locking function? Any object has a friction angle. When the object is subjected to an external force in the friction angle, no
matter how large the force is, the object will not be displaced. This is called self-locking. What is the principle of self-locking? Self-locking needs to meet some conditions Adding a reverse torque to the helical gear-worm wheel gearbox gear produces a reverse efficiency η'=2-1/η, which is significantly less than the forward
efficiency η. If the forward efficiency η ≤ 0.5, the hardened worm wheel gearbox gear is decelerated. The opportunity is self-locking. The hard-tooth worm wheel gearbox
with only a small number of large speed ratios is statically self-locking. The principle is: when the lead angle of the worm wheel gearbox is smaller than the equivalent friction angle between the meshing teeth, the mechanism
has self-locking property, and the reverse self-locking can be realized, that is, the worm wheel gearbox wheel can only be driven by the worm wheel gearbox , and the
worm wheel gearbox can not be driven by the worm wheel gearbox wheel. For example, in the self-locking worm wheel gearbox mechanism used in its heavy machinery, the reverse
self-locking property can serve as a safety protection.

WP cast iron worm wheel gearbox and NMRV aluminum alloy turbine worm wheel gearbox worm wheel gearbox structural features: A large gear ratio can be obtained, which is more compact than the staggered helical gear mechanism. The two-wheel meshing tooth surface is a line contact, and its bearing capacity is much higher than that of the crossed-axis helical gear
mechanism. The worm wheel gearbox drive is equivalent to a screw drive and is a multi-tooth mesh drive, so the drive is smooth, the noise is small and self-locking. When the lead angle of the worm wheel gearbox is smaller than the equivalent friction angle between the meshing teeth, the mechanism has self-locking
property, and the reverse self-locking can be realized, that is, the worm wheel gearbox wheel can only be driven by the worm wheel gearbox , and the worm wheel gearbox can not be
driven by the worm wheel gearbox wheel. For example, in the self-locking worm wheel gearbox mechanism used in its heavy machine, the reverse self-locking property can
play a safety protection role. In the device. The worm wheel gearbox transmission is derived from the staggered shaft helical gear transmission. The pinion of the pinion
is wound on the cylindrical surface for more than one week. Such a pinion is shaped like a screw and is called a worm wheel gearbox . The large gear is
called a worm wheel gearbox gear. In order to improve the meshing condition, the busbar of the worm wheel gearbox wheel indexing cylindrical surface is changed into a
circular arc shape, so that the worm wheel gearbox is partially wrapped, and the worm wheel gearbox wheel is processed by a hob having the same shape and parameters
as the worm wheel gearbox , so that the tooth contact is in line contact. Can transmit more power.

P series worm wheel gearbox structure: The basic structure of WP series worm wheel gearbox is mainly composed of transmission parts worm wheel gearbox gear, shaft, bearing, box and its
accessories. The WP series worm wheel gearbox can be divided into three basic structural parts: box, worm wheel gearbox gear, bearing and shaft
combination. The cabinet is the base of all the accessories in the WP series worm wheel gearbox . It is an important accessory for supporting
the fixed shaft components, ensuring the correct relative position of the transmission components and supporting the load on the WP series
worm wheel gearbox . The main function of the WP series worm wheel gearbox is to transmit the motion and power between the two staggered
shafts. The main function of the bearing and the shaft is the power transmission, operation and efficiency.

Maintenance and maintenance of WP series worm wheel gearbox : 1. Please do not apply pressure to the output parts of the WP series worm wheel gearbox during installation. Please meet the corresponding
requirements of coaxiality and verticality between the machine and the WP series worm wheel gearbox when connecting. 2. The WP series worm wheel gearbox should be re-exchanged after initial operation for 400 hours, and the oil change interval thereafter is
about 4000 hours. 3, WP series worm wheel gearbox gear reduction chassis should retain enough lubricant in the body, and check regularly. 4. Pay attention to keep the appearance of WP series worm wheel gearbox clean, and remove dust and dirt in time to facilitate heat dissipation.

Features of worm wheel gearbox transmission:

it is a special staggered shaft helical gear transmission, the stagger angle is ∑=90°, the transmission ratio is large and accurate. Usually the number of spirals of the worm wheel gearbox is the number of screws, if the number of worm wheel gearbox heads is z1, the worm wheel gearbox gear When the number of teeth is z2, the transmission ratio of the worm wheel gearbox drive is 2=n1/n2=z2/z1ω1/ωi=(3-60), usually the number of worm wheel gearbox heads is small (z1=1~4), and the number of teeth of the worm wheel gearbox gear is many (z2=30~ 80), so the worm wheel gearbox drive can obtain a large transmission ratio and make the mechanism more compact. The single-stage worm wheel gearbox drive transmission ratio i ≤ 100 ~ 300; when transmitting power, i = 5 ~ 83.

It has some characteristics of the screw drive, the worm wheel gearbox is equivalent to the screw, the worm wheel gearbox wheel is equivalent to the nut, and the worm wheel gearbox wheel partially accommodates the worm wheel gearbox . worm wheel gearbox material and worm wheel gearbox gear material not only need to have sufficient strength, but more importantly, have good running performance, wear resistance and anti-gluing performance. The worm wheel gearbox drive often uses bronze or cast iron as the ring gear of the worm wheel gearbox gear, matching the hardened and ground steel worm wheel gearbox .

The transmission is smooth and noise-free. Because the meshing between the worm wheel gearbox and the worm wheel gearbox gear is continuous, the meshing teeth are more.

Regarding the self-locking problem, not all worm wheel gearbox gears can be used. When the spiral angle of the worm wheel gearbox is smaller than the equivalent friction angle of the meshing surface, self-locking can be achieved. = 0.4 to 0.45. η = 0.82 to 0.92. η = 0.75 to 0.82; when z1 = 3 to 4, η = 0.7 to 0.75; when z1 = 2, η

The transmission efficiency is relatively low. Only 60%, lower than the of the same class.

Because of the large sliding speed at the meshing position, it will produce more severe friction and wear, causing heat and deteriorating the lubrication condition. Therefore, the worm wheel gearbox wheel is generally made of precious metals such as bronze.

The noise of the turbine worm wheel gearbox is mostly related to the lack of precision, while the overheating is related to the small gap. Usually these two
problems come back at the same time, indicating that the precision of the manufacturing is not enough. The solution is to adjust the position
of the worm wheel gearbox shaft through the two ends. Adding or subtracting the gasket adjustment, the noise as long as it is not higher than 70 decibels is
normal, and the running noise will be much lower. Good lubrication will also improve noise and overheating. Generally, the lubricating oil will
not pass through 1/3 of the worm wheel gearbox .
