Zhengzhou turntable bearing 134.45.2240.002 wholesaler

Zhengzhou slewing bearing 3...wholesale/ ' (3,3,3) - The slewing bearing is a large bearing that can withstand comprehensive loads. It can withstand large axial, radial loads and overturning moments at the same time. . It has been widely used in shipbuilding equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.
/ ' (3,3,3) - Common noises from slewing bearings (slewing bearings) and solutions
/ ' (3,3,3) - ① How to control dust noise
/ ' (3,3,3) - If there are foreign objects such as dust in the slewing branch, non-periodic vibration will occur. The so-called dust sound, the magnitude of the vibration and noise is variable, and may or may not exist.
/ ' (3,3,3) -Methods to control dust noise: Improve the cleaning method of slewing bearings/turntable bearings. Before installation, strictly clean the bearings, shafts, seat holes and matching parts to remove the lubricant. Foreign matter improves the sealing of bearings and avoids the use of plastic cages with impure materials or embedded foreign matter.
/ ' (3,3,3) - ② How to control scratch sound
/ ' (3,3,3) - If there are cracks, indentations or rust on the rolling surface of the slewing bearing, it will Periodic vibrations and noises occur like riveting rivets. The period may be fixed but mostly has a certain corresponding relationship with the rotation speed. The scars will occur continuously on the channel, and the scars will appear and disappear on the steel ball. Moreover, this Noise varies with installation and lubrication conditions.
/ ' (3,3,3) -Methods to control this type of noise: Do not knock the bearing during installation. Prevent the bearing from rusting when assembling the bearing with the shaft and then installing it into the bearing seat. Use high viscosity grease to prevent shock and vibration during transportation.
/ ' (3,3,3) - ③ Noise caused by lubrication factors and its countermeasures
/ ' (3,3,3) - Wrong lubricant selection, insufficient lubricant or aging and hardening, All of them can cause the slewing bearing/turntable bearing to produce vibration and noise, and this noise has no certain rules. In this case, the only way is to select a suitable lubricant, adjust its lubricant amount, extend the service life of the lubricant and reasonably determine the replacement cycle.
