Gearbox Typical Failure Modes, Detection and Mitigation Methods
Gearboxes can fail in drastically different ways Data: 257 gearbox damaged records Bearings: 70%; gears: 26%; and others: 4% Observations: • Both bearing and gear failures are concentrated in the parallel section • Top failure mode is high-speed shaft (HSS) or intermediate-speed shaft (IMS)
4 Warning Signs of slewing ring Problems
6/12/2018· Check bearing clearance with a dial indior that measures how much the structure tilts when the boom is loaded. Grinding, popping, or clicking noises from the bearing typically mean there could be inadequate lubriion and/or excessive wear in the raceway, or loose bolts. As noted previously, greasing the bearing and purging lubricant is a

- 3 Ways to Avoid Failure When Mounting a Slewing Ring - igus
Whether a slewing ring uses ball bearings or sliding elements to facilitate movement, failure can occur if an improper mounting surface is used. If mounted to an uneven base, the wear surface of the slewing ring bearing will receive the majority of the load in an uneven pattern, and as a result; its load-handling capabilities can be seriously compromised.
