Abstract
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.
Claims18
A wind turbine gearbox repair assembly comprising:
- 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 being part of a gearbox of a wind turbine;
- 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;
- and
- a cutting tool configured to cut a surface of the gearbox housing such that the bore in the gearbox housing is of sufficient size to receive the sleeve.
A wind turbine gearbox repair assembly comprising:
- a sleeve having (i) an inner diameter configured to receive a bearing assembly that includes an outer race and a first notch and (ii) an outer diameter configured to fit within a bore of a gearbox housing that is part of a gearbox of a wind turbine;
- a cutting tool;
- a first retaining plate configured to be attached to the gearbox housing, the first retaining plate including a pin configured to engage the first notch of the bearing assembly to prevent the outer race of the bearing assembly from rotating in the bore relative to the gearbox housing;
- and
- a second retaining plate configured to mount the cutting tool to the gearbox.
