A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing supported by the housing, and a bearing rotatably supporting the spindle. The spindle has an outer race. And, the outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Rotary power tool including transmission housing bushing

An expansion tool includes a housing, a collar rotatably coupled to the housing, a plurality of jaws coupled for co-rotation with the collar, a mandrel movable relative to the housing between a retracted position and an extended position to expand the jaws, and a drive mechanism including a rotatable cam. Rotation of the cam moves the mandrel between the retracted position and the extended position. The expansion tool further includes an indexing gear configured to incrementally receive torque from the drive mechanism such that continuous rotation of the drive mechanism incrementally rotates the indexing gear, and a clutch assembly including a clutch gear meshed with the indexing gear, a clutch cover surrounding the clutch gear, and a plurality of rolling elements disposed between the clutch gear and the clutch cover. The clutch cover is drivably coupled to the collar such that rotation of the clutch cover rotates the collar.

Expansion tool

A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.
