Summary of Common Knowledge of Reduction Motor in Life
The characteristics of deceleration motor are high efficiency and reliability, long working life, simple maintenance and wide application. Its series can be divided into single-stage, two-stage and three-stage gear reducer motors. The main installation and layout methods are expansion, coaxial and shunt.
1. In the expansion type of two-stage cylindrical reducer motor, the gear is asymmetrical relative to the supporting position. When the shaft is deformed by bending and torsion, the load is unevenly distributed in the tooth width. Therefore, the shaft should be designed with greater stiffness and keep the gear away from the input end or the output end.
2. The characteristics of shunt type of two-stage cylindrical reducer motor: the position of the outward extension axis of shunt type reducer motor can be extended from any side to facilitate the overall configuration of the machine. The shunt grade gears are all helical teeth, with one side turning right and one side turning left to offset the axial force. One of the axes should be able to swim slightly in order to avoid slight axial movement. Stuck the gear.
3. The characteristics of coaxial deceleration motor are compact in radial dimension but large in axial dimension. Because the middle axle is bigger and the axle is more disturbed when it is loaded, the load concentration along the tooth width is more serious. At the same time, because the center of the two-stage gear must be consistent, it is difficult to make full use of the bearing capacity of the telling gear, and the bearing lubrication in the middle part of the deceleration is also difficult. The input and output terminals of the deceleration motor are located at both ends of the same axis, which limits the overall configuration of the transmission device.
