We should understand that the elevator of the Elevator Lift should be stable and vibration-free during normal operation, and the coupling of the worm and the worm is a basic requirement for smoothness in a good state. If the worm and the worm wheel are worn out, the flank clearance will increase, which will cause the car to vibrate during operation. In this case, the spacer of the bearing base at both ends of the worm shaft can be adjusted. If the worm gear shaft of the reducer is an eccentric shaft structure, the bolt of the worm wheel eccentric shaft bearing cap can be loosened, and the lateral gap of the twist can be adjusted by rotating the shaft.
The range of the gap on the flank is adjusted according to the specifications of each manufacturer because it is directly related to the lubricating oil, structure, tooth profile, processing technology, and the like. During the start-up and braking process of the elevator, the car will have a large impact vibration during the commutation and speed change operation, which is probably caused by the increase of the axial clearance caused by the wear of the screw thrust bearing. . At this time, the worm shaft end flange can be opened, and then the worm shaft end nut and flange paper pad can be adjusted or a new thrust thrust bearing can be replaced. The range of axial clearance should be adjusted according to the specifications of each manufacturer. The flank clearance and axial play must be adjusted by experienced and professionally trained personnel. The lubricating oil in the elevator casing of the elevator elevator should be added at any time according to the position of the oil level indication. The tank can be cleaned or replaced with new oil every 6 months. And the lubricant is recommended to use No. 150 or No. 320 oil from Lanzhou Refinery. There is no oil leakage in the joint between the peephole, the cover or the bearing cap and the case. If the protruding end of the worm is sealed, it is necessary to observe the dripping condition at any time. Under normal circumstances, it is 1 drop in 3-5 minutes. At this time, the end cap nut of the packing can be adjusted, but not too tightly squeezed, in order to avoid the failure of the worm holding shaft. If the protruding end of the worm is a mechanical seal structure, it should be replaced if there is oil leakage. Moreover, the rolling bearing on the worm wheel shaft should be filled with 35g of calcium-based grease per month, which is to ensure 2/3 of the space filled with the bearing chamber. The temperature rise of the gearbox should not be higher than 60 degrees Celsius, and the maximum oil temperature should not be higher than 80 degrees Celsius. If it is found that the rolling bearing produces uneven noise, knocking sound or temperature is too high, it should be repaired or replaced in time. Therefore, always check the bolts at the reducer coupling of the elevator elevator, there should be no looseness.
