Premium gearbox

premium gearbox is an important part of the fan, its main function is to drive the generator to generate electricity by accelerating the rotation of the rotor shaft. A kind of
In addition to transmission components, the gearbox also includes detection system, lubrication system, control system, heating system, cooling system and so on. A kind of
The gearbox of 1.5MW fan is driven by two-stage planetary gear and one-stage parallel shaft gear. I. Planetary Gear Transmission
1. Advantages of planetary premium gearbox:
1)
Small size, small mass, compact structure, large carrying capacity
Generally speaking, under the same load conditions, the outer dimensions and mass of planetary gear transmission are about ordinary.
1/2-1/5 of gear transmission. (2)
High transmission efficiency
Due to the symmetry of the planetary gear transmission structure, the reaction force acting on the central wheel and the rotating arm bearing can be balanced with each other, so as to improve the transmission efficiency. Generally, its efficiency value can reach 0.97-0.99. (3)
The transmission is larger,.
In planetary gear transmission, which is only used to transmit motion, its transmission ratio can reach several thousand. Moreover, when the transmission ratio of planetary gear transmission is large, it can still maintain many advantages such as compact structure, small mass and small volume. (4)
Smooth motion, strong shock and vibration resistance.

Premium gearbox
Because several planetary wheels with the same structure are uniformly distributed around the center wheel, the force between the planetary wheel and the rotating arm can be balanced. At the same time, it also increases the number of teeth involved in meshing, so planetary gear transmission has smooth movement, strong ability to resist impact and vibration, and reliable work.   2. The disadvantages of planetary gear drive are:   1)   high quality material;   2)   complex structure;

Premium gearboxPremium gearbox

premium gearbox, the typical representative premium gearbox, when I was a child played four-wheel drive, the motor has three gears, that can be understood as a premium gearbox, through the transmission of power gear.

Transmission box, four-drive car, the output torque first to the transmission box, through the transmission box, the power to the front and rear differential.It can be understood as dividing a force into two or more components

Gearbox, by changing the transmission ratio, to get a different speed, the car gear, very easy to understand

Transmission box, similar to the gearbox, but not necessarily what is inside, may be belt, chain, gear, etc.There are only gears in the ear premium gearbox

The invention relates to a manufacturing method of a one-way transmission premium gearbox

Technical field:

The utility model relates to a mechanical device, in particular to a driving mechanism of a premium gearbox which can only carry out one-way transmission.

Background technology:

The ratchet mechanism is mostly used in one-way transmission, because the structure occupies a large volume, it has certain limitations on the occasion of use.To realize one-way transmission in the interior of the small premium gearbox, based on the principle of ratchet mechanism, this practical and novel patent proposes to use 20CrMnTi material after heat treatment processing oblique bar for one-way transmission, only to change the part structure, do not take up any space in the premium gearbox, reducing the volume of the premium gearbox.

Premium gearbox

Utility model content the utility model is realized through the following technical scheme a one-way transmission premium gearbox, it includes the input shaft, circle, ball bearing, insulation gasket, enclosure, baffle, output shaft, shaft sleeve, which in the casing of one end of the output shaft and is connected with a wedge, the wedge keys and two springs extrusion connection, in a wedge shape keys and two spring gasket buffer between the two, the force transmission between the input shaft and output shaft through the gear.Preferably, a one-way transmission premium gearbox is provided in which the connection direction of the wedge key and the spring is perpendicular to the radial direction of the output shaft.The wedge face of the wedge key faces the direction of the output shaft, and the plane of the wedge key is connected to the spring.The wedge Angle of the wedge key is 45 60.C.The unidirectional driving mechanism in the utility model comprises an input shaft, a unidirectional oblique key, a driving gear, an output gear shaft, etc.The one-way oblique key on the input shaft is connected to the driving gear through a spring.When the input shaft rotates counterclockwise, due to the action of the spring, the oblique key is fully combined with the driving gear. The driving gear rotates counterclockwise to drive the output gear shaft to rotate and realize the power transmission of the premium gearbox.When the input shaft rotates clockwise, due to the oblique plane of the oblique key, when the input shaft rotates, the input shaft slides relatively with the driving gear, and the power cannot be transmitted, so as to realize one-way transmission.The mechanism is simple in structure, small in volume and easy to use.

Wind power equipment gearbox
Complete drive solution
The ZOLLERN Group has three production sites in Germany and China, and its experience in the field of wind turbine power transmissions began in 1988 with the first main drivebox for its customers. Today ZOLLERN has become a supplier of transmissions for wind energy applications. The company provides customers with pitch, yaw drive and fan main speed increaser.
The fan main gearbox converts the relatively low blade speed to the higher speed required by the generator, while the pitch and yaw devices optimize the output power of the wind power plant. Depending on the model, each wind turbine is equipped with three to four yaw premium gearboxes, each with a yaw premium gearbox to adjust the angle of the blades according to the wind conditions.

Features and benefits of the ZOLLERN transmission:

Pitch and yaw drive, Sogear is one of the market leading manufacturers of this type of transmission. Pitch and yaw drives for all power grade wind turbines are available.

Methods/steps

In order to ensure the safety and normal operation of the machinery, it is necessary to improve the reliability of gear transmission. On the one hand, it is necessary to improve the design, machining accuracy and assembly quality 

The diagnosis method of gearbox fault can be divided into two categories: one is to use the signal processing method to complete the fault analysis and diagnosis through the vibration, noise, oil temperature and other dynamic signals generated in the process of gear operation;The other is based on the theory of friction and wear, lubrication oil analysis to achieve the purpose of fault diagnosis 

Mechanical premium gearbox gear in the transmission operation, due to the poor manufacturing, operation and maintenance, etc., may lead to the fault of the gear.Therefore, gear faults can be divided into two categories: one is caused by manufacturing and assembly reasons, such as gear error, gear and internal hole different center, the axis of each part is not in the center, imbalance.

The other kind is gear formed due to the long run, usually tooth surface under the load is very big, both the relative between two meshing tooth rolling, and to have the relative sliding, so in the long run will cause the gear surface pitting, fatigue spalling wear, plastic flow, agglutination and tooth root fractures, even broken teeth, etc.

premium gearbox operation maintenance is according to the requirement of the manufacturer to carry out daily and regular maintenance, gearbox gear case of machine cleaning maintenance using the original to the discharge of oil system and after filtering the old oil cleaning, especially for the premium gearbox can be realized in the process of running premium gearbox, premium gearbox of abnormal operation, to timely records related to the operation data, and compared with the running premium gearbox.Identify and solve problems in time.
