Multi-mode drill and transmission sub-assembly including a gear case cover supporting biasing |
摘要 |
A multi-mode drill can include a transmission to transfer torque from an output member of a motor to an output spindle. A transmission housing encloses the transmission in an interior cavity formed by a gear case shell and a cover plate. The cover plate can be coupled to the outer shell via screws. A static shift rod can be supported at one end by the cover plate. A shift bracket can be mounted on the shift rod and biased to a mode position by a biasing member exerting a force between the shift bracket and the cover plate. A shift pin can be supported adjacent one end by the cover plate and biased to a mode position by a biasing member exerting a force between the shift pin and the cover plate. A spindle biasing member can bias the output spindle against the cover plate. The shift pin can actuate an electronic switch. A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.
