Abstract
The present disclosure is directed to a gearbox repair apparatus for repairing a bore hole of a gearbox torque arm. In certain embodiments, the apparatus includes a mounting structure configured to mount to the torque arm. The mounting structure includes a through hole that aligns with the bore hole of the torque arm when mounted thereto. As such, when mounted to the torque arm, the mounting structure is configured to locate a boring bar at a center of the bore hole such that the boring bar is perpendicular to a face of the torque arm. Further, the mounting structure is configured to receive the boring bar through the aligned through hole and bore hole such that, when inserted therethrough, the boring bar is configured to machine and thus repair the bore hole.
Claims6
An apparatus for repairing a bore hole of a gearbox torque arm, the apparatus comprising:
- a mounting structure configured to mount to the torque arm, the mounting structure comprising a first mounting plate, a second mounting plate, and a plurality of connecting members, each of the plurality of connecting members being positioned through and between each of the first and second mounting plates so as to secure the first and second mounting plates together on opposites sides of the torque arm, the first and second mounting plates each comprising a respective through hole, wherein, when the mounting structure is arranged with the torque arm, the through holes of the first and second mounting plates and the bore hole define a continuous channel;
- and
- a boring bar secured to the mounting structure,
- wherein, when the mounting structure is arranged with the torque arm, the channel is configured to locate the boring bar such that the boring bar is perpendicular to a face of the torque arm, the boring bar being configured to repair the bore hole;
- the apparatus further comprising:
- a plurality of support members, wherein the plurality of support members comprise a first set of support members and a second set of support members, the first set of support members being mounted to the first mounting plate, the second set of support members being mounted to the second mounting plate;
- a first end plate;
- a second end plate;
- a first set of connecting plates configured between the first end plate and the first set of support members;
- and
- a second set of connecting plates configured between the second end plate and the second set of support members.
