A new finite element approach for the analysis of slewing

Jan 29, 2015· Several analytical models have been proposed to estimate the load distribution and the deformation of slewing bearing asselies in wind turbine generators (WTGs). Even though they are a useful tool for designers as a first approach, most of them assume rigid rings and rigid supporting structures, leading to inaccurate results; even if compliance is considered …

slewing drives, slewing ring drive, slew drive

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together. Slewing ring drives are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and asseling them into a finished gearbox.

slewing ring bearing assely Internal gear with Good

The housing of the slewing mechanism is fixed on the turntable, and a pinion gear is used to mesh with the ring gear on the inner race of the slewing bearing. The pinion can rotate on its own axis or revolve around the centerline of the turntable. When the turning mechanism is working, the turntable will rotate relative to the chassis.
