Abstract
An oscillating power tool includes a drive motor (M) producing rotary motion and an oscillating mechanism (30) for converting the motor rotary motion to an oscillatory side-to-side movement. The oscillating mechanism (30) includes a link (32) driven by an eccentric shaft (16) of the motor (M), a drive arm (40) that drives the hub (45) of the working tool (B) in oscillating motion, and a bearing arrangement (37) between the drive arm (40) and the link (32) that isolates relative rotation and translation between the components while still imparting an oscillatory motion to the drive arm (40).
