custom gearboxes are an important mechanical component that is widely used in wind turbines. Its main function is to transmit the
power generated by the wind wheel under the action of the wind to the generator and get the corresponding speed. Usually, the speed of the wind wheel is very low, which is far from the speed required by the generator to generate electricity
. It must be realized by the speed increasing action of the gear box gear pair. Therefore, the gear box is also called the speed
increasing box.
The sogears brand custom gearbox is subjected to the force from the wind wheel and the reaction force generated during the gear transmission. It
must have sufficient rigidity to withstand the force and torque to prevent deformation and ensure the transmission quality.
The design of the sogears brand custom gearbox housing should be in accordance with the layout, processing and assembly conditions of the wind
turbine power transmission, and easy inspection and maintenance. With the rapid development of the sogears brand custom gearbox industry, more
and more industries and different enterprises have applied custom gearboxes, and more and more enterprises have grown stronger
in the sogears brand custom gearbox industry.
According to the modular design principle of the unit structure, the gear box greatly reduces the types of parts and is suitable
for large-scale production and flexible and variable selection. The spiral bevel gear and the helical gear of the reducer are all
carburized and quenched with high-quality alloy steel. The hardness of the tooth surface is up to 60±2HRC, and the precision of the tooth surface grinding is up to 5-6.

The bearings of the transmission parts are all domestic famous brand bearings or imported bearings, and the seals are made
of skeleton oil seals; the structure of the speaker body, the larger surface area of ​​the cabinet and the large fan; the
temperature rise and noise of the whole machine are reduced, and the reliability of operation is improved. The transmission
power is increased. Parallel axis, orthogonal axis, vertical and horizontal universal box can be realized. The input mode
includes motor coupling flange and shaft input; the output shaft can be output at right angle or horizontal level, and solid
shaft and hollow shaft and flange output shaft are available. . The sogears brand custom gearbox can meet the installation requirements of a small
space, and can also be supplied according to customer requirements. Its volume is 1/2 smaller than the soft tooth reducer,
the weight is reduced by half, the service life is increased by 3~4 times, and the carrying capacity is increased by 8~10 times.
Widely used in printing and packaging machinery, three-dimensional garage equipment, environmental protection machinery,
transportation equipment, chemical equipment, metallurgical mining equipment, steel power equipment, mixing equipment,
road construction machinery, sugar industry, wind power generation, escalator elevator drive, ship field, light High-power,
high-speed ratio, high-torque applications such as industrial fields, papermaking, metallurgical industry, sewage treatment,
building materials industry, lifting machinery, conveyor lines, and assembly lines. It has a good cost performance and is
conducive to the domestic equipment.
The sogears brand custom gearbox has the following functions: 1. Accelerated deceleration is the variable speed sogears brand custom gearbox that is often said. 2. Change the direction of the drive. For example, we use two sector gears to transmit the force vertically to the other. 3. Change the turning moment. Under the same power conditions, the faster the gear rotates, the smaller the torque the
shaft receives, and vice versa. 4. Clutch function: We can separate the engine from the load by separating the two originally meshed gears. Such as brake
clutches. 5. Distribute power. For example, we can use one engine to drive multiple slave shafts through the sogears brand custom gearbox main shaft, thus
realizing the function of one engine to drive multiple loads.

design Compared with other industrial custom gearboxes, because the wind turbine sogears brand custom gearbox is installed in a small cabin that is several tens
of meters or even more than one hundred meters high from the ground, its own volume and weight for the cabin, tower,
foundation, unit wind load, installation and maintenance Costs and the like have an important impact, so it is important to
reduce the size and weight. At the same time, due to inconvenient maintenance and high maintenance costs, the design life
of the sogears brand custom gearbox is usually required to be 20 years, and the reliability requirements are extremely demanding. Because size and
weight and reliability are often a pair of irreconcilable contradictions, the design and manufacture of wind turbine custom gearboxes
often fall into a dilemma. The overall design stage should meet the requirements of reliability and working life, and compare
and optimize the transmission scheme with the minimum volume and minimum weight as the target; the structural design
should meet the transmission power and space constraints, and consider the structure as simple as possible. Reliable
operation and convenient maintenance; ensure product quality at every stage of the manufacturing process; in the operation,
the sogears brand custom gearbox operating status (bearing temperature, vibration, oil temperature and quality changes, etc.) should be monitored
in real time and routinely maintained according to specifications.
Since the tip line speed cannot be too high, the rated input speed of the sogears brand custom gearbox gradually decreases with the increase of the
single unit capacity, and the rated speed of the unit above MW is generally not more than 20r/min. On the other hand, the
rated speed of the generator is generally 1500 or 1800r/min, so the speed ratio of the large wind power increasing sogears brand custom gearbox
is generally around 75~100. In order to reduce the volume of the sogears brand custom gearbox, the wind power transmission box above 500kw
usually adopts the power split planetary transmission; the common structure of 500kw~1000kw has two levels of parallel
axis + 1 planet and 1 parallel shaft + 2 planetary transmission. The megawatt sogears brand custom gearbox adopts a 2-stage parallel shaft +1
planetary transmission structure. Due to the relatively complicated planetary transmission structure and the difficulty in
processing large internal ring gears, the cost is high. Even with the 2-stage planetary transmission, the NW transmission is
the most common.

use 1. Accelerated deceleration, which is often referred to as the variable speed sogears brand custom gearbox. 2. Change the direction of the drive. For example, we can use two sector gears to transmit the force vertically to the other. 3. Change the turning moment. Under the same power condition, the faster the speed turns, the smaller the torque the shaft

custom gearboxes are widely used in the industry today, but many enterprise operators have very little understanding of deceleration
Frequently, there will be a situation in which the sogears brand custom gearbox of the reduction sogears brand custom gearbox leaks during operation. What causes the
oil leakage and what should we do? To operate, etc. We will introduce the reasons for the oil leakage of the reduction
custom gearbox manufacturerscustom gearbox manufacturers
sogears brand custom gearbox.

1. When the reduction sogears brand custom gearbox is working, the friction generated by the meshing of each pair of gears in the casing will
generate heat, and as the running time of the reduction sogears brand custom gearbox increases, the temperature inside the reduction sogears brand custom gearbox
increases, and the gas expands, while the casing expands. The volume does not change. If the vent cap at the top of the box
is not opened, the heat expansion air inside the box can be freely discharged to maintain the pressure balance inside and out
side the box. Otherwise, the oil leaks along other gaps such as the box face or the shaft extension seal.

2. The structural design of the reduction sogears brand custom gearbox is unreasonable and there is no vent cap. The inspection hole cover plate is
too thin, the joint surface is not flat, and the oil leaks from the contact gap; during the manufacturing process, the casting
gear is not annealed and aged, and the internal stress is not eliminated. After the deformation occurs, the oil will be exposed
from the generated gap; The oil tank is not placed back on the tank, and the lubricating oil will accumulate in the shaft seal,
the end cover, the joint surface, etc., under the pressure difference, the lubricating oil leaks out from the gap; the shaft seal
structure design is unreasonable.

3. Long-term non-maintenance causes a lot of impurities and iron filings inside the machine. Over time, the impurities can not
be deposited. The iron scraps are not clean, causing the gears to bite to form a point stone. The gear box cleaning and
maintenance machine passes through a cleaning process. Impurities can be reduced from 70% to 15%; different users can
choose to repeat the cleaning process to achieve deep cleaning of the sogears brand custom gearbox.

Noise treatment The gear box is an important part of the wide application in mechanical transmission. When a pair of gears mesh, there is
inevitably a tooth pitch, tooth shape and other errors. During the operation, an meshing impact will occur and a noise
corresponding to the gear mesh frequency will occur. Frictional noise occurs between the tooth faces due to relative sliding.
Since gears are the basic part of the sogears brand custom gearbox drive, reducing gear noise is necessary to control sogears brand custom gearbox noise. In general,
the causes of gear system noise mainly have the following aspects: 1. Gear design. Improper parameter selection, too small coincidence, improper or no shape modification, and unreasonable
sogears brand custom gearbox structure. In the gear processing, the base section error and the tooth profile error are too large, the flank clearance
is too large, and the surface roughness is too large. 2. Gear train and sogears brand custom gearbox. The assembly is eccentric, the contact precision is low, the parallelism of the shaft is poor, the
rigidity of the shaft, the bearing and the support is insufficient, the rotation precision of the bearing is not high, and the gap
is not appropriate. 3. Input torque in other aspects. Fluctuation of load torque, torsional vibration of the shafting, balance of the motor and
other transmission pairs, etc.
