Description

(54) Single-ended clutch

The invention relates to mechanical engineering, in particular to devices for transmitting rotation.

A one-turn clutch is known, containing two coupling halves and a ClJ remote switching mechanism.

The disadvantage of it is the complexity of the design, since the switching mechanism is implemented remotely.

Closest to the present invention is a one-turn clutch, containing a leading coupling half, made in the form of a clip, the driven coupling half arranged concentrically in it, made in. A star shape, mounted to them in the separator, the rollers and the switching mechanism with a radially movable stop, with the grooves under the ynopL2j in the separator and zedohodke.

The disadvantage is low operational capability due to one-sided construction.

The purpose of the invention is to enhance the wada} nosti with reverse wringing.

The goal is achieved by the fact that in a single-turn clutch containing a leading coupling half, made in the form of a clip, there is a driven coupling half-coupling, made in the form of an asterisk, mounted by a roller in the separator the switching mechanism is made out of an operating ring mounted on the separator and spring-loaded along the axis of rotation to the coupling half, and in the separator and asterisk are made

15 radial grooves under the support.

Claims (2)

The single turn coupling contains a leading coupling box 1 with an internal cylinder-shaped surface, a driven popumuft located in it, a prismatic multifaceted sprocket 2 rigidly mounted on the driven shaft, a separator 3 that sits freely on the sprocket 2, rollers 4 located in the slots of the separator 3. ensuring that rollers 4 are constantly ready for wedging between the working surfaces of the drive cage 1 and the driven sprocket 1 2, is the friction ring 5, which sits freely on the neck of the separator 3 and is axially spring-loaded SRI springs used. The axial direction of the separator 3 is limited by the ring 7, tin: mounted on the sprocket 2. The switching on mechanism 8 contains the flanges of the separator 3 and the ring 7, which have grooves under the controlled stop 9. In the initial position of the coupling the controlled stop 8 is inserted into the cut-outs of the separator 3 and the ring 7. In this case, the asterisk is fixed by the stop 8, and the rollers 4 are removed from jamming and are held by the separator 3 in the middle of the working sites of the asterisk 2; The drive ring 1 rotates without transmitting movement. The leading casing 1 is connected with the driven sprocket 2 by withdrawing the stop 8 from the sepa cutouts of the eator 3 and the ring 7. The friction ring 5 will turn the separator 3 with the rollers 4 relative to the sprocket 2 through the springs 6 through the springs 6 1 and an asterisk 2 and turn on the coupling. Having finished one turn, the inserted stop 9 will enter the cut-out of the separator 3 and stop it. Separator 3, turning relative to asterisks 2, will place the rollers 4 of the seizures. When the cutouts on the flanges of the separator 3 and the ring 7 are aligned, the stop 9 will return to its original position and fix the sprocket 2. The simplicity of manufacture, ease of control and the possibility of obtaining a specific rotation in both directions favorably distinguish the proposed coupling from the known single turn couplings. Tests of the proposed coupling showed its reliable operation and a clear fixation of positions during rotation in both directions. Claims of the invention One-turn clutch containing a leading coupling half, made in the form of a clip, a driven half coupling located concentrically in it, made in the form of an asterisk, rollers mounted between them in the separator and a stop mechanism movable in the radial direction, differing in that in order to increase reliability in reverse rotation and simplify the design, the inclusion mechanism is implemented in the form of a friction ring mounted on a separator and spring-loaded along the axis of rotation to the coupling half, and this in a separator and sprocket provided with radial slots for the emphasis.
