What inspections are required for geared motor assembly?

Dongzheng Motor is an enterprise that develops and produces gear drive mechanism products, and produces low-noise, high-quality gear boxes, gear motors, gear box motors and other products. Among them, the geared motor is familiar to most people, and the geared motor refers to the integration of the reducer and the motor. Usually, it is integrated and assembled by a professional reducer manufacturer and supplied with the motor as a whole.

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.

When Dongzheng Motor produces and assembles the geared motor, it must strictly follow the requirements of the above points to check the quality of the product. Zhaowei Electromechanical develops and produces miniature reduction gearboxes, reduction motors and other products, which are used in industrial drives, smart homes, robots and other fields.

What are the skills of using the geared motor?

The geared motor plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is a relatively precise machine. However, due to the harsh working environment of the geared motor, failures such as wear and leakage often occur. In order to reduce the occurrence of failures, we must first understand the usage skills of the geared motor.

1. The user should have reasonable use and maintenance rules and regulations, and carefully record the operation of the geared motor and the problems found in the inspection. During the work, when it is found that the oil temperature rises above 80°C or the oil pool temperature exceeds 100°C and abnormal In case of normal noise and other phenomena, stop using it, check the cause, eliminate the fault, and replace the lubricating oil before continuing to run.

2. When changing the oil, wait until the deceleration motor cools down and there is no danger of burning, but it should still be kept warm, because after cooling, the viscosity of the oil increases and it is difficult to drain the oil. Note: Cut off the power supply of the drive device to prevent unintentional power on.

3. After 200~300 hours of operation, the oil should be changed for the first time, and the quality of the oil should be checked regularly in the future use. The oil mixed with impurities or deteriorated must be replaced in time. Generally, for long-term continuous operation of the geared motor , according to the operation of 5000 hours or once a year to replace the new oil, the deceleration motor that has been out of service for a long time should also be replaced with new oil before re-running. Oils of the same but different viscosities are allowed to be mixed.
