A gearbox repair assembly is disclosed herein. The gearbox repair assembly includes a sleeve having an inner diameter configured to receive a bearing assembly and an outer diameter configured to fit within a bore of a gearbox housing. The gearbox housing can be part of a gearbox of a wind turbine. The gearbox repair assembly further includes a retaining plate configured to be attached to the gearbox housing for preventing an outer race of the bearing assembly from rotating in the bore relative to the gearbox housing. Also provided are methods to repair such a gearbox. The gearbox repair assembly and related methods reduce the time and cost needed to repair the gearboxes.

Methods of repairing a torque converter that enable the continued use of a torque converter and result in a repaired torque converter with a higher-strength and more durable construction. In some examples, a backing ring can be replaced with a replacement backing ring that includes a spline ring for replacing the function of a cover spline ring. In some examples, a method of repairing a torque converter can be improved by providing a replacement backing ring with a radial protrusion for locating the backing ring on the cover, and a method of determining an axial location of the radial protrusion.

A gearbox may include a gearbox case with a wear sleeve disposed within a shaft bore, and a gear assembly mounted on a shaft and disposed within the shaft bore. The gear assembly may include a bearing that engages the wear sleeve. A method of repairing a gearbox case may include uncoupling a top piece and a bottom piece of the gearbox case, forming an oversize bore in a shaft bore of the gearbox case to remove a damaged area, and installing a wear sleeve in the oversize bore.

A clutch is configured to mechanically establish and disestablish a torque transmission path between an input shaft through which a torque is input and an output shaft through which the torque is output. The clutch includes a sun gear, an internal gear, planetary gears, and a carrier. The sun gear is configured to switch between a fixed state and a non-fixed state. The internal gear is coupled to the input shaft in a torque transmittable manner. The planetary gears are configured to mesh with the sun gear and the internal gear. The carrier is coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably. The carrier includes a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch.
