By Howard W Penrose, Ph.D., CMRP President | MotorDoc LLC Properly assessing an operating turbine’s electrical and mechanical systems is no easy task. An electrical signature analysis or ESA is independent of load or speed, so the test is often applied to analyze generators and electric equipment. Still, a challenge is to ensure loading stays constant…
Dry lube bearing says goodbye to grease
SKF DryLube Bearings eliminates need for grease relubrication while performing reliably and almost maintenance-free over a wide temperature range. These next-generation high-temperature bearings especially suit hostile and extreme-temperature applications. SKF DryLube Bearings are filled with a dry lubricant based on graphite or molybdenum disulfide with a resin binder. The dry lubricant is injected into the…
Better Bearings for Wind Turbine Reliability
Replacing failed bearings in wind-power equipment is no easy task. But after 20 years of concentrated effort, bearing manufacturers have devised designs that carry loads that fluctuate with wind gusts and work well in electric fields around generators. Viewers of this Webcast will hear presenters discuss the problems with bearing that shorten their life and…
Wear-resistant bearings for wind equipment
High on the list of O&M crews are ways to extend bearing life and reducing wear. To handle the challenge, Timken engineers developed a bearing that reduce life-limiting wear problems that trouble main shaft and gearbox bearings. Common wear problems include micropitting on main shafts, spherical-roller bearings and micropitting, smearing and brittle flaking for wind-turbine-gearbox…
