Abstract

Изобретение относитс к машиностроению и может быть использовано дл передачи крут щего момента в исполнительных устройствах роботов и манипул торов. Цель изобретени - повышение надежности и долговечности. Муфта состоит из двух полумуфт в клиновых разнонаправленных полост х, между которыми расположены тела заклинивани в виде роликов 3. На ступице ведущей полумуфты установлены диски 4 и 5. Ролики 3 закреплены с возможностью вращени на дисках 4 и 5. При включении соленоида 8 закрепленные на коре толкатели 10, 11 вход т в отверсти в дисках и поворачивают их в разные стороны, что ведет к выталкиванию роликов из зоны заклинивани и разъединению полумуфт. Включение полумуфт осуществл етс при отключенном соленоиде под действием пружин. 1 з.п.ф-лы, 3 ил.The invention relates to mechanical engineering and can be used to transmit torque in actuators of robots and manipulators. The purpose of the invention is to increase reliability and durability. The coupling consists of two half couplings in wedge multidirectional cavities between which the jamming bodies are located in the form of rollers 3. Disks 4 and 5 are mounted on the hub of the leading half coupling. The rollers 3 are fixed with the possibility of rotation on the disks 4 and 5. When the solenoid 8 is turned on, they are fixed on the bark the pushers 10, 11 enter the holes in the discs and turn them in different directions, which leads to the pushing of the rollers from the jamming zone and the separation of the coupling halves. The coupling half is switched on when the solenoid is turned off by the action of springs. 1 hp ff, 3 ill.

Claims

Claim

1. A switch-off clutch containing leading and driven half-couplings, concentrically located working surfaces of which form alternating wedge cavities, rolling elements located in wedge cavities and spring-loaded relative to one of the half-couplings towards the narrow part of the cavity, as well as a rolling mechanism for controlling the rolling elements the fact that, in order to increase reliability and durability, the control mechanism is made in the form of two coaxial disks with openings partially overlapping one another mounted on the leads conductive coupling half to rotate in opposite directions solenoid mounted on the drive coupling half and the armature with attached to it a tapered pushers arranged with the possibility of axial movement and interaction of the pushers with the holes of disks and rolling bodies arranged on the discs rotatably.

2. The coupling according to claim 1, characterized in that the rolling elements located in the wedge cavities of one direction are mounted on one disk, and the rolling elements located in the wedge cavities of another direction are fixed on another disk.
