A spindle lock assembly (410, 710) for a power tool (10) includes a first rotatable part (904, 704) fixedly connected to an output member (404) of a power tool transmission (16), and a second rotatable part (426, 726) fixedly connected to the power tool output spindle (430) and operatively engaging the first rotatable part. A lock ring (908, 708) surrounds the first and second rotatable parts. The lock ring being is retained in the housing in a substantially stationary manner with a dampener (954, 754) disposed between the lock ring and the power tool housing (772) and to dampen movements of the lock ring relative to the housing in a rotational direction. The spindle lock assembly transmits rotary motion from the transmission output member to the output spindle when the rotary output member is being driven by the motor and inhibits transmittal of rotary motion from the output spindle to the transmission output member when the output spindle is driven by an external force. |
