Abstract
A rotationally driven air tool configured to be capable of retaining a lubricant in a gear of a rotation transmitting mechanism as long as possible has an air motor (14), a rotation transmitting mechanism (18) transmitting rotational driving force from a rotational output shaft (12) of the air motor to a rotary tool member (15), e.g. an abrasive disc, and a housing (28) having a motor chamber (20), a rotation transmitting chamber (22), a partition (24) between the motor chamber and the rotation transmitting chamber, and an air blow port (72) provided to extend through the partition to blow air discharged from the air motor toward a peripheral wall surface of the rotation transmitting chamber.
Claims6
A rotationally driven air tool comprising:
- an air motor having a rotational output shaft;
- a rotation transmitting mechanism comprising a gear rotated by rotational driving force received from the rotational output shaft to transmit the rotational driving force to a rotary tool member;
- and
- a housing comprising a motor chamber accommodating the air motor, a rotation transmitting chamber accommodating the rotation transmitting mechanism, a partition between the motor chamber and the rotation transmitting chamber, and an air blow port provided to extend through the partition to blow at least a part of air discharged from the air motor toward a peripheral wall surface of the rotation transmitting chamber.
