Abstract
A torque limiter includes a friction mechanism, a pressure plate, a first side plate, an urging member, and a second side plate. The friction mechanism includes a first friction member and a second friction member. The pressure plate includes a first contact surface and a plurality of first drainage grooves. The first contact surface is a surface that makes contact with the first friction member. The first drainage grooves radially extend. The second side plate includes a second contact surface that makes contact with the second friction member. The second side plate is disposed on a second side with respect to the second friction member in an axial direction. The second side plate is attached to the first side plate to be unitarily rotated therewith.
Claims4
A torque limiter comprising:
- a friction mechanism including a first friction member and a second friction member, the first friction member having an annular shape, the second friction member having an annular shape, the second friction member disposed on a second side with respect to the first friction member in an axial direction;
- a pressure plate having an annular shape, the pressure plate disposed on a first side with respect to the first friction member in the axial direction, the pressure plate including a first contact surface and a plurality of first drainage grooves, the first contact surface making contact with the first friction member, the plurality of first drainage grooves disposed on the first contact surface to be apart from each other at intervals in a circumferential direction, the plurality of first drainage grooves radially extending;
- a first side plate disposed on the first side with respect to the pressure plate in the axial direction;
- an urging member disposed between the pressure plate and the first side plate, the urging member configured to urge the pressure plate to the second side in the axial direction;
- and
- a second side plate disposed on the second side with respect to the second friction member in the axial direction, the second side plate attached to the first side plate to be unitarily rotated therewith, the second side plate including a second contact surface, the second contact surface making contact with the second friction member;
