A mechanical drive for a dual action motor that is used with an oscillating spindle sander is disclosed. The oscillating spindle sander has a worktable for supporting a workpiece. A spindle extends upwardly through the worktable and has a sanding surface. An electrical motor is supported by the worktable and includes a shaft for imparting rotational motion to the spindle. The mechanical drive is contained within a housing that is supported by the motor and is connected to the motor shaft for imparting reciprocal or axial motion in addition to rotary motion to the spindle. The mechanical drive includes a speed reducer that is coaxial with the motor shaft. The speed reducer drives a cam follower that engages a cam in the housing for imparting reciprocal motion to the spindle at a rate much less than the rotational speed imparted to the motor shaft by the motor. The speed reducer includes a cycloidal gear that engages a complementary ring gear provided in the housing. The mechanical drive for the dual motion motor is disclosed as being particularly useful in connection with oscillating spindle sanders; however, other applications are also contemplated.
