Abstract

The invention relates to mechanical engineering, in particular, to devices for connecting machines and mechanisms with a shaft, and can be used, for example, in textile production for connecting shaft shafts and exhaust machines while ensuring synchronous rotation. The purpose of the invention is to increase reliability by providing a gapless coupling coupling at high torques. When the clutch is activated by the spring 10 squeezing the housing 9 of the locking device, move along the drive shaft 1 and the ring 16. With its end conical surface, first capture the lead surfaces 8 ends of the levers 6, and then the wedge-shaped ends of the levers 6 and presses them into inclined the grooves of the disc 3. By making the grooves of the dogs longer than the working stroke of the body 9, the latter can move at high torques to maintain a zero clearance in the coupling half couplings. 5 il.

Claims (1)

Claim A switch-off clutch containing a drive and driven coupling halves mounted on the shafts, the first of which is made in the form of a disk with grooves, and the second in the form of a sleeve and spring-loaded levers pivotally mounted on the sleeve with the possibility of engagement with the grooves of the disk, a locking device made in the form of a cylindrical body installed with the possibility of axial movement, and means for fixing the housing in the form of spring-loaded dogs, characterized in that, in order to increase reliability by providing a clearance-free connection of the coupling halves and large torques, it is equipped with a thrust ring rigidly fixed to the shaft of the driving half coupling, a pushing device in the form of crackers, an annular guide is made on the cylindrical body, freely covering the shaft of the driving half coupling, and the end conical surface from the side facing the drive half coupling disk made with a mating conical outer surface and inclined surfaces of 5 grooves, dogs are made with longitudinal grooves at the ends, mounted on a ring and connected to those installed in the housing breadcrumbs by means of pins located in the grooves, and the levers are made with wedge-shaped ends in the cross section and lead-in surfaces arranged to contact the end conical surface of the housing, the latter is spring-loaded relative to the ring in the direction of the coupling, and the length of the grooves of the dogs is greater than the working stroke of the housing when turned on couplings.
