What are the main reasons for the axial play movement of the motor?
The axial magnetic force generated by the motor stator and rotor, the axial external force the motor received during operation, the axial force generated by the internal air circuit of the motor, and the incorrect motor installation method.
What is the standard of motor axial movement?
The ball bearing is allowed to move 0.5 mm axially;
The sliding bearing is allowed to move 0.5 mm to on side axially for the motor capacity of 10 KW and below.
How to correctly install the motor within the allowable range of axial movement?
Take planetary geared motor as an example. This motor is widely used in DC Motor, stepping motor, servo system and other drive systems due to its small size, high transmission efficiency, wide ratio range and high accuracy.
1. Before installation, carefully clean and check the connecting components of the planetary reducer to avoid unnecessary wear. Check whether the size of the motor connection part of the planetary reducer is applicable. Here is mainly the matching tolerance of the positioning boss, output shaft and the installation size of the reducer.
2. When installing the transmission part on the output shaft, the motor and the reducer shall be naturally connected under the condition that the egocentricity of the motor input shaft and the reducer output shaft are consistent. The motor and planetary gearbox need to be installed closely to avoid gaps.
3. The gearbox shall be firmly installed on a stable and horizontal base, and the installation shall be tight and stable, otherwise vibration and noise will occur during operation, and the bearing and gear will be damaged.
4. Ensure the accuracy of the installation position of the reducer and conduct no-load running test for at least 2 hours. The operation shall be stable without any impact, vibration, noise and oil leakage.
In the process of using the planetary geared motor, the installation methods has a great impact on the subsequent use experience.
