A reduction motor is an integrated body of a reducer and a motor (motor). This integrated body is also commonly referred to as a gear reduction motor or a gear reduction motor. Usually, the reduction motor is produced in a factory, integrated and assembled, and then supplied as a set with the motor.
During the assembly process of the reduction motor, the following inspections need to be carried out:
(1) Torsional vibration inspection
The torsional vibration value is an important parameter for measuring the quality of the reduction motor. Considering the actual working conditions, a force of 15kN (vehicle weight) is applied to the motor. The vibration speed of the reduction motor in this case is required to be less than 2.8mm/s, and there is no abnormal vibration. The main testing instruments are torsional vibration meters and torsional vibration sensors. In order to simplify the testing process, a testing tooling needs to be designed independently. The control requirements are the same as the airtightness inspection, which is a routine inspection and must be inspected for each unit.
(2) Airtightness inspection
For reduction motors, oil leakage often occurs during actual operation due to poor airtightness of the reduction box. Therefore, airtightness inspection (oil leakage) is very necessary. The specific method is: during the assembly process of the reducer, before the refueling process, this test is carried out, and the reducer is pressurized to 0.1 5MPa through a press. Under this condition, it is required that there is no leakage for 20 seconds, that is, the pressure remains unchanged. The main testing instrument is a precision pressure gauge. The control requirement is to have this testing process during the assembly process of the reducer, and to make a test record for each motor.
When Chaoya produces and assembles reduction motors, it must strictly follow the above requirements for inspection to ensure quality. chaoya develops and produces micro reduction gearboxes, reduction motors and other products, which are used in industrial drives, smart homes, robots and other fields
