Processing and maintenance of gear parts of precision planetary gear reducer

The processing of gear parts of precision planetary gear reducer needs maintenance. First of all, the precision planetary gear reducer can only be installed on a flat, shock-absorbing and torsion resistant support structure. In any case, it is not allowed to use a hammer to drive the pulley, coupling, pinion or sprocket into the output shaft, which will damage the bearing and shaft.

The precision planetary gear reducer has the advantages of space saving, reliability and durability, high overload capacity, power up to 200KW, low energy consumption, superior performance, reduction efficiency up to 95% and above, low vibration, low noise, rigid cast iron box, gear surface after high-frequency heat treatment and precision machining, forming helical gear and bevel gear. The gear reducer is a reducer dedicated to various reactors. Its gear adopts Gleason hypoid tooth type, and the gear is hard tooth surface. It has the characteristics of large bearing capacity, low noise, long life, high efficiency, smooth operation, etc. The overall performance is far superior to cycloidal pin gear reducer and worm gear reducer, and has been widely recognized and applied by users.

The gear module in the precision planetary gear reducer is a very important knowledge point. The higher the module gear teeth are, the thicker they will be. The module refers to the ratio (m=t/π) of the tooth pitch t and the circumference π between two adjacent gear teeth on the same side of the tooth profile. The unit is mm. Module is a basic parameter of modular gear teeth. The greater the modulus. If the number of teeth of the gear is fixed, the radial dimension of the gear is larger. The module series standards are formulated according to the requirements of design, manufacturing and inspection. For gears with non straight teeth, the module has the normal module mn, the end face module ms, and the axial module mx. They are all based on the ratio of their respective tooth pitch (normal tooth pitch, end face tooth pitch, and axial tooth pitch) to pi, and are also in millimeters. The module of bevel gear can be divided into big end module me average module mm and small end module m1. For tools, there are corresponding tool modules, such as mo, which are widely used.
