The speed limit ferris wheel bearing raceway noise solution

The speed limit is the maximum speed allowed in ferris wheel bearing load, lubrication condition, and the bearing type, size, load magnitude and direction, lubrication, clearance, cage structure and cooling conditions and many other factors.
Factors affecting the speed limit: load size, Slewing drives load type and direction, lubricant and lubrication method. Experience shows that: to improve the manufacturing precision, bearing the appropriate to increase the bearing clearance, the cage material and special structure, but also can improve the speed limit bearing.
The reason of high temperature of bearing: lubricating oil quality does not meet the requirements or deterioration, the oil viscosity is too high; mechanism assembly tight (spaces); one-way preloaded bearing; bearing race rotation on the shaft or shell; overload; bearing retainer or rolling body fragmentation.

Rolling bearing is allowed in the work of the minor operation noise, if the sound is too loud or unusual noise or impact sound, it indicates that the bearing failure.
