Description

(5Y COUPLING CLUTCH

one

The invention relates to mechanical engineering and can be used in test benches for transmitting torque and quickly connecting and disconnecting shafts with axial and angular displacements.

Known coupling coupling, containing two coupling halves, made in the form of hubs with flanges, in one of which fingers with tapered shanks are fixed, and in the second holes for fingers are made, while fingers are provided with elastic bushings lj.

The disadvantage of this coupling is the limited operational capabilities that prevent axial and angular displacements of the connected shafts.

The purpose of the invention is the expansion of operational capabilities.

This goal is achieved in that the coupling has a flanged coupling half and a coupling half made in the form of a sleeve with a flange.

interacting by means of fingers with tapered shanks fixed to the flange, fitted with an annular ring between the flanges with an axial clearance relative to the sleeve with holes for the fingers and a disk with face cams, while the grooves for the cams are made in the ring.

In addition, the coupling can be provided with elastic fingers, spaced between the sleeve and the ring and the disk.

FIG. 1 shows a coupling, a general view, in FIG. 2, a section A-A in FIG. one.

The clutch contains the coupling half 1, made in the form of a sleeve with a flange, and the coupling half 2, in the flanges of which are fixed the fingers 3 with conical shanks C ,, On the sleeve placed

Claims (2)

20 elastic rings 5. Between the flanges of the half coupling there is a ring 6 with holes 7 With lead chamfers 8 under the fingers and a disk 9 with cams 10, 3 A disk with cams and a ring are pressed to the coupling half by the pressure ring 11. The number of fingers of the half coupling is less than the number of holes with chamfer The coupling operates as follows. A sleeve with a cam disc 9 attached to it and a ring 6 with holes is seated on the drive shaft, which has the ability to move reciprocally along the axis. In the reciprocating movement, the fingers 3 enter (when connected) or exit (when disconnected) from the holes of the ring 6. The holes in the ring 6 have large lead-in chamfers and are arranged in a circle so that the lead-in chamfers are in contact with each other . Thus, the fingers 3 with their lead-in cones fall into the holes of the ring 6 at any position along the lumuffs relative to each other. The proposed coupling provides the ability to quickly connect and disconnect shafts having axial 3 and angular displacements of the connected shafts. Claim 1. A coupling coupling comprising a flanged coupling half, a coupling half made in the form of a sleeve with a flange, interacting through fingers with tapered shafts fixed in the flange, characterized in that, in order to increase the compensating possibilities, it is fitted with flanges installed with axial flanges a gap with respect to the sleeve, a ring with holes for the fingers and a disc with end cams, with grooves for the cams in the ring, 2. A coupling according to claim 1, characterized in that it is provided with elastic rings placed between the sleeve and the ring and the disk.
