The geared motor refers to the integration of the reducer and the motor (motor).This integrated body is also commonly referred to as a geared motor or a geared motor.Usually by a professional reducer manufacturer, after integrated assembly, it will be supplied in a complete set with the motor. 16MM plastic planetary gearbox
The geared motor needs to be inspected in the following aspects during the assembly process:
(1) Torsional vibration test
The torsional vibration value is an important parameter to measure the quality of the geared motor.Considering the actual working conditions, adding a force of 1 5kN (vehicle weight) to the motor requires the vibration speed of the geared motor to be less than 2.8mm/s in this case, and there is no abnormal vibration.The main detection instruments are torsional vibration meter and torsional vibration sensor. In order to make the detection process simple, a detection tool needs to be designed independently.The control requirements are the same as the airtight inspection, which is a routine inspection and must be inspected for each unit.
(2) Air tightness inspection
For geared motors, oil leakage often occurs during actual operation due to poor airtightness of the gearbox, so airtight 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 0.15MPa through the press.Under this condition, it is required to be airtight for 20s, that is, the pressure remains unchanged.The main testing instrument is a precision pressure gauge.The control requirement is to have this inspection process in the assembly process of the reducer, and make an inspection record for each motor.
