How to use and maintain the reducer daily

1 Equipment and adjustment

A sort of.In order to ensure the accuracy of the reducer (reduced motor) equipment, it is not necessary to start the equipment and do not damage the sealant.You can open the oil inspection cover or use kerosene (diesel) to clean the anti-rust grease on the gear surface.

b. Elastic couplings, gear couplings or other non-rigid couplings can be selected between the reducer and the motor or the main engine.

c.The reducer should be stable and firm, and the base adjustment gasket should be cut (select steel gasket).The concentricity error with the coupling must not exceed the allowable value of the coupling used.

d. Check whether the bolts on the sealing surface of the box are loose, and if they are loose, tighten them from the beginning.

2 Operation and maintenance

A sort of.Before the reducer is officially put into operation, a load test must be carried out.

b. Before the test run with load, add lubricating oil according to the direction of the oil level pointer, and turn the output shaft by hand for a circle.Be sensitive, and then work for two hours without abnormal noise.

c.During the test run with load, it should be gradually loaded to full load (if possible, it should be loaded in four times of 25%, 50%, 75% and 100%).The working time of each period is not less than 2 hours, and it should be stable without shock, vibration and oil leakage.The lubricating oil in the machine can only be used after it is confirmed to be free of defects or filtered through a 200-mesh filter.

d. If there is any abnormality during the debugging process, the cause should be found out, cleaned up, and the manufacturer should be notified immediately.

e. The reducer (reduced motor) should be overhauled every six months when it is working.In the future, check the tooth surface regularly (weekly) for defects such as pitting, scratches, and adhesions.If the defect area exceeds 20% along the tooth length and tooth height direction and continues to develop, the gear pair should be replaced.

3 lubrication

A. The gear adopts oil pool lubrication and circulation lubrication.According to the equipment instructions, lubricating oil should be used.The reducer with soft tooth surface and medium hard tooth surface is N100~150, and the reducer with hard tooth surface and planetary gear surface is N220~320.

b. Lubricating oil should be checked and replaced on time.When the new equipment reducer is used for the first time, it must be replaced after 10-15 days of operation.In the future, the oil quality should be checked on time (2-3 months), and the oil should be replaced in time if it is found not to meet the requirements.Generally speaking, the oil should be changed at least every six months.When testing the oil quality, if one of the following situations occurs, the lubricating oil should be replaced in time:

——The content of foreign matter in lubricating oil exceeds 2%;

- metal abrasives in lubricating oil exceed 0.5%;

- the water content in the lubricating oil exceeds 2%;

c.In the normal maintenance of the reducer, first check whether there is oil leakage, check the liquid level in the tank in time, whether the lubrication is good, whether the screws everywhere are stable, check the temperature of the equipment in time, bite the wire into the meshing position of the gear, and measure the gear teeth of wear and tear.
