TORQUE LIMITER

摘要

Provided is a torque limiter that allows a prescribed torque value to be set with a great freedom. A roller (58) provided on one end of a lever member (54) selectively engages an engagement recess (44), and the other end of the lever member (54) is connected to an end of a tension spring (62) to urge the lever member (54) in the direction to engage the one end of the lever member (54) in the engagement recess (44).

主权项

1. A torque limiter for transmitting a torque of a limited value between a first rotatable member and a second rotatable member disposed on a common central axial line, comprising:
an engagement recess formed in an inner peripheral part of the first rotatable member; a lever member having an intermediate part pivotally attached to the second rotatable member about a rotational center line extending in parallel with the central axial line of the second rotatable member and one end configured to selectively engage the engagement recess; and a tension spring having an end engaged by the second rotatable member and another end engaged by another end of the lever member, the tension spring urging the lever member in a direction to cause the one end of the lever member to engage the engagement recess; wherein the lever member consists of a bell crank.
