What are the installation methods for the deceleration motor

Small speed regulating motors, also known as reduction motors in daily life, are characterized by high efficiency and reliability, long working life, easy maintenance, and wide application. Its series can be divided into single stage, two-stage, and three-stage gear reduction motors, and the installation layout mainly includes expansion type, coaxial type, and split type.

1. In the unfolding type of a two-stage cylindrical reduction motor, the gears are asymmetric relative to the support position. When the shaft undergoes bending and twisting deformation, the load distribution in the tooth width is uneven. Therefore, the shaft should be designed with greater stiffness and keep the gears away from the input or output end.

2. The characteristics of the split type of the two-stage cylindrical reduction motor: The position of the extended shaft of the split type reduction motor can be extended from either side, which is convenient for the overall configuration of the machine. The gears of the split stage are all made into helical teeth, with one side turning right and the other side turning left to offset axial force. One of the shafts should be able to move slightly axially to avoid jamming the gears.

3. The characteristics of coaxial deceleration motors are: compact radial dimensions but larger axial dimensions. Due to the large size of the intermediate shaft, the shaft experiences significant deflection under load, resulting in severe load concentration along the tooth width.
At the same time, due to the fact that the centers of the two stage gears must be consistent, it is difficult to fully utilize the load-bearing capacity of the first stage gears, and the lubrication of the bearings located in the middle part of the reduction is also relatively 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.

From an installation perspective, it can be divided into vertical and horizontal types, which mainly depends on the usage environment.
