Adjustment and maintenance of winches



After the winch is installed, it must be checked and adjusted.

1, open gear drive, the backlash is 0.42 mm, its contact area along the tooth height is not less than 40%, the length of the extension is not less than 50%.

2 、 check whether the transmission system of the brake is flexible and reliable, and adjust the clearance between the brake shoe and brake wheel when the brake is not over 0.7-0.8mm.

3. Check whether the transmission system of the brake is flexible and reliable, and adjust the clearance between the brake shoe and brake wheel when the brake is not over 1.5mm.

Electrical control and main motor is 4 interlocking and inspection of brake and safety brake, start working brake motor brake, brake stops the main motor is working, and only the safety brake release to start the main motor.

Winch lubrication

1 、 the reducer is lubricated with winter gear oil or saturated cylinder oil, and the oil surface shall ensure that all the worm is immersed in the oil. The reducer is changed to oil once a year.

2, spindle bearings and reducer output shaft bearings should be replaced regularly or supplement No. 4 calcium base grease, two years change oil.

3, before each drive, the gear should be filled with lubricating oil.

4, the rest of the lubrication parts should be in each drive before refueling lubrication, especially in the reducer output shaft, between the two gear thrust ring and movable gear shaft should be filled with lubricating oil.

Test run of winch

After the installation of the winch has been checked and adjusted, the lubrication parts shall be lubricated and lubricated. The no-load test run will be carried out, and the load will be carried out after winding. The load will be gradually loaded to the rated load. At the standard voltage, the current is not higher than the rated value, the motor, the reducer and other parts are not exothermic.
