Higher Timken bearing ratings create new opportunity for wind turbine power train designers

10/24/2012 8:00:00 AM | Bearing Ratings | Comments | Jerry Fox |

For the last 26 years, application engineers at The Timken Company have been successfully applying the Timken 1986 bearing rating C90 in bearing life calculations for all the industries that we serve with the exception of the wind industry. For wind turbine bearing applications, our application engineers apply the ISO bearing rating C1 in bearing life calculations because the certification bodies for new wind turbines have stipulated that practice in order to promote more transparency among all the bearing suppliers. Read More+

Using integrated flexpin technology to help increase gear box reliability

3/16/2010 4:00:00 PM | Bearing Applications | Comments | Jerry Fox |

I spend a lot of time thinking about gear box technology for wind turbines. In my position, I’ve had the opportunity to review engineering layouts of many conventional and new gear box designs – some of which are still on the drawing board. Modern day innovation is at work in the wind energy industry, no doubt, but virtually all designs continue to include some form of a planetary gearing system. While there are some really good gear box designs that still adhere to conventional practice, there are also advanced concepts that are pushing the envelope. These designs incorporate new technologies that are intended to attack failure modes to help increase reliability and performance. One example of this is flexible pin technology.  Read More+

Optimizing parallel-shaft system performance through reliable bearing designs

2/18/2010 11:00:00 AM | Bearing Applications | Comments | Jerry Fox |

I recently read a report about an offshore wind farm project and how poorly performing gearbox bearings used in the intermediate and high-speed shaft positions resulted in unplanned work, negatively impacting O&M costs. Corrective actions were made but the example reinforces how important correct gearbox bearing designs can be to an investment. Tapered roller bearing designs used in the locating positions of the gearbox can help to maximize the bearing’s load carrying capacity, center the shaft for improved sealing and gear contact and eliminate opportunities for roller skidding or raceway smearing. Read More+

Higher bearing ratings for lean turbine design

1/12/2010 3:00:00 PM | Bearing Ratings | Comments | Jerry Fox |

It used to be that only ISO ratings could be applied to calculating bearing L10 life. Now, Germanischer Lloyd has approved Timken bearing ratings for Timken tapered and cylindrical roller bearings in wind turbine applications. Join the discussion on how these higher ratings can offer new opportunities for downsizing the power train and creating leaner, more competitive designs. Read More+
