摘要： A clutch or brake unit is described with an automatic wear adjustment mechanism.Clutches and brakes operate by the engagement of friction members (4,6) which experience wear in use requiring a larger stroke of the unit to effect engagement. This results in delayed clutch or brake operation which can be a serious disadvantage where prompt action is required. Conventionally this wear has been compensated by replacement of the worn friction members or by manual adjustment of them resulting in temporary disablement of the unit and requiring service personnel time.In the inventive unit, friction members (4,6) are mounted between pressure members (10,2) and an actuator (12) operates against a backing member (15) to effect clutch or brake actuation and de-activation by movement of the friction members towards and away from each other, and the position of at least one of the pressure members is adjusted automatically in response to wear of the friction members. Sprags, ratchet mechanisms, screw threads and tension springs are alternatively described for adjusting this position and the wear can be sensed by a proximity switch or microswitch. Pneumatic and hydraulic mechanisms are also described.
摘要翻译：用自动磨损调节机构描述离合器或制动单元。离合器和制动器通过摩擦构件（4,6）的接合来操作，摩擦构件（4,6）在使用中经历磨损，需要更大的冲程以实现接合。这导致延迟的离合器或制动器操作，这在需要快速动作的情况下可能是严重的缺点。通常这种磨损已经通过更换磨损的摩擦件或通过手动调节来补偿，从而导致设备暂时停用并要求维修人员的时间。在本发明的单元中，摩擦构件（4,6）安装在压力构件（10,2）之间，并且致动器（12）抵抗背衬构件（15）操作，以实现离合器或制动器致动，并通过摩擦构件朝向和远离彼此，并且响应于摩擦构件的磨损自动地调节至少一个压力构件的位置。交替地描述弹簧，棘轮机构，螺纹和拉伸弹簧用于调整该位置，并且磨损可由接近开关或微动开关感测。还描述了气动和液压机构。
