How to divide the modules is the key problem in the modular design of gear motor. The types of modules are small, the degree of universality is high, and the processing batch is large, which is beneficial to reducing the cost. However, from the external considerations of the system, the design should be a comprehensive analysis of the overall product, function, performance and cost, in order to reasonably determine the type and quantity of modules.
From the perspective of several professional factories abroad, the module of the gear motor can be divided into four categories according to the function of the power module, the transmission module, the connection module and the additional module. The modules can be refined. Such as power module: can establish shaft, bearing, box, gear, oil seal and other modules. Try to consider the commonality of the modules in the whole series. If the gear design is optimized and analyzed, the helix Angle β=20°, the tooth width coefficient Φ=0.35, and the modulus, the number of teeth, and the displacement coefficient are also consistent. In this way, the gear is universal as a module. As mentioned above, in the center distance of Germany's Mannesmann Demag AF series reducer, the first stage center distance of the frame number AF06 is consistent with the second stage center distance of AF05, and the first stage of AF07 is consistent with the second stage of AF06, and the whole series is based on this. The main consideration is the versatility of the gear module in the series.
The domestic has developed a combination of reducer, motor reducer, motor reducer with braking function. It is the prototype of modular combination of gear reduction motor in China.
Gear motor general failure cause: a reducer overheating
1) Overload
2) Insufficient or excessive lubricating oil
b Abnormal stable running noise
1) Rotation/grinding noise, bearing damage
2) Knocking noise, irregular meshing
c Abnormal unstable running noise
Oil contamination or insufficient oil
d Ventilator oil leakage
1) Too much oil
2) Ventilator installation is not correct
e Oil leak seal is damaged
