TORQUE HINGE OR TORQUE LIMITER

摘要

A torque hinge or torque limiter includes external and internal cylindrical members that are capable of relatively rotating, and a coil spring placed between the external and internal cylindrical members. A first circumferential portion is formed on a front-end side of the inner periphery of the external cylindrical member. A second circumferential portion is formed on a rear-end side of the outer periphery of the internal cylindrical member. The torque value that blocks the rotary torque of the external or internal cylindrical member in a first arbitrary direction is set by pressing the first circumferential portion against the outer circumferential portion of the coil spring. The torque value that blocks the rotary torque of the external or internal cylindrical member in a second arbitrary direction is set by pressing the second circumferential portion against the inner circumferential portion of the coil spring.

主权项

1. A torque hinge comprising:
an external cylindrical member and an internal cylindrical member that are placed so as to be capable of relatively rotating; and a coil spring placed between an inner periphery of the external cylindrical member and an outer periphery of the internal cylindrical member, wherein a first circumferential portion extending in a direction in which an inner diameter of the external cylindrical member decreases is formed on a front-end side of the inner periphery of the external cylindrical member, a second circumferential portion extending in a direction in which an outer diameter of the internal cylindrical member increases is formed on a rear-end side of the outer periphery of the internal cylindrical member, the coil spring is forcibly inserted into the first circumferential portion of the external cylindrical member, and the second circumferential portion of the internal cylindrical member is forcibly inserted into the inner circumferential portion of the coil spring.
