Summary of common sense of deceleration motor in life

Deceleration motor is characterized by high efficiency and reliability, long service life, easy maintenance, widely used. Its series can be divided into single stage, two stage and three stage gear reducer motor, and the installation arrangement mainly has expansion type, coaxial type and shunt type.

The 1 and two stage cylindrical gear motor expansion, gear bearing position relative to the axial asymmetry, lead to bending deformation, the load on the tooth width distribution is not uniform, so the shaft should be designed with large stiffness, and the gear from the input or output.

2, two cylinder motor deceleration characteristics of shunt type: extended shaft position shunt type gear motor can be controlled by any stretch, to facilitate the overall configuration of the machine, the gears are made to shunt grade helical gear, right side, left side, to counteract the axial force, which should make a shaft can do a move in the axial direction, so as to avoid blocking gear.

3, coaxial deceleration motor characteristics: radial size is compact, but the axial size is larger. Because the middle shaft is larger, the load of the axle is larger when the axle is loaded, so 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 gear, and the lubrication of the bearing 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.
