Machining and maintenance of gear parts of precision planetary gear reducer

The machining of the gear parts of the precision planetary gear reducer needs maintenance. First, the precision planetary gear reducer can only be installed on a flat, shock-absorbing and anti-twist support structure. Under any circumstances, it is not allowed to hammer the pulley, coupling, pinion or sprocket into the output shaft, which will damage the bearing and shaft.

Precision planetary gear reducer has the advantages of space saving, reliability and durability, high overload capacity, power up to 200KW, low energy consumption, excellent performance, reduction efficiency up to 95%, low vibration, low noise, rigid cast iron box, gear surface after high-frequency heat treatment, precision processing, forming helical gear and bevel gear. The gear reducer is a special reducer for various reaction kettles. Its gear adopts Gleason quasi-hyperbolic tooth type, and the gear is hard tooth surface. It has the characteristics of large bearing capacity, low noise, long service life, high efficiency, and stable operation. The performance of the whole machine is far better than the cycloidal pinwheel reducer and worm gear reducer, which 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 tooth is, the thicker it is. The module refers to the ratio of the tooth pitch t and the circumference π (m=t/π) between the two adjacent gear teeth on the same side of the tooth profile, in millimetres. Module is the most basic parameter of modular gear teeth. The greater the modulus. If the number of teeth of the gear is fixed, the radial size of the wheel is also larger. The module series standard is 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 module ms is different from the axial module mx. Both are based on the ratio of the respective tooth pitch (normal tooth pitch, end tooth pitch and axial tooth pitch) to the circumference, and are also in millimeters. For the module of bevel gear, there are two parts: the average module of large end me mm and the module of small end m1. For tools, there are corresponding tool modules, such as mo, which are widely used.
