Description

The invention relates to mechanical engineering and can be used, for example, to connect shafts, two mechanisms that require their frequent separation.

The purpose of the invention is to increase the speed of the separation of the shafts by spontaneous displacement of one of the sleeves and simplify the design.

The drawing shows the clutch Assembly, section.

On the shafts 1 and 2 are placed tapered split sleeves 3 and 4, and the sleeve 4 is covered by the inner conical bore of the sleeve 3. The sleeve is placed in a conical

If it is necessary to disconnect the shafts, the fastening element 6 is unscrewed from the thread of the sleeve 5 a few turns. The sleeve 4, having a conical surface angle greater than the wedging angle, freely (spontaneously) emerges from the inner conical bore of the bushing 3 and expands, freeing the shaft 2. For unclamping the sleeve 3 having an external cone angle equal to or smaller than the wedge angle, 10 with a light blow to the fastening element 6, move the sleeve 5 to the left.

The use of the proposed coupling allows an increase in the speed of the connection and separation of the shafts.

the hole in the sleeve 5, on the external thread ko-. In case of equal diameters of the shafts, it is possible that the fastener 6 will be screwed in, the mixing and fixing of the coupling on any

and assisting with its inner end with the end of the sleeve 4.

The installation of the coupling is carried out as follows.

A sleeve 5 is placed on the shaft 1, a fastener 6 is mounted on the shaft 2. Then the sleeves 3 and 4 are mounted on the shaft ends so that the sleeve 4 enters the inner conical bore of the sleeve 3. The fastener 6 is screwed onto the thread of the sleeve 5 until it touches the inner the end with the end of the sleeve 4.

As the bolt 6 is screwed in, the sleeve 4 moves the sleeve 3 in the conical hole of the sleeve 5, since the angle of the mating conical surfaces of the latter is smaller than the angle of the conical surfaces of the internal bore of the sleeves 3 and 4. After the cylindrical hole of the sleeve 3 is backless, it spans the shaft 1 and its internal conical bore is fixed in this position by the sleeve 4, moving in the bore of the sleeve 3, the shaft 2 is gaplessly covered.

of them without prior complete disassembly. Invention Formula A quick-release coupling for connecting the shafts, supporting the split sleeves mounted on the respective shafts and interacting with each other with tapered outer surfaces, axially aligned by means of a fastener mounted on the threaded hole of the outer sleeve that surrounds the sleeve, and the taper angle of the outer surface of the outer sleeve equal to the angle of self-braking, characterized in that, in order to increase the speed of separation of the shafts due to spontaneous axial displacement of one of the bushings and simplify the design, it contains two bushings, one of which is made with an inner conical bore located centrally opposite the shaft, the inner surface of the sleeve is made conical, and the angle of the bore cone and the outer surface of the second sleeve adjacent to it is greater than the self-locking angle. If it is necessary to disconnect the shafts, the fastening element 6 is unscrewed from the thread of the sleeve 5 a few turns. The sleeve 4, having a conical surface angle, a larger wedging angle, freely (spontaneously) emerges from the inner conical bore of the sleeve 3 and expands, releasing the shaft 2. To open the sleeve 3, which has an outer cone angle equal to or less than the wedge angle, you need to lightly strike the fastening element 6 to move the sleeve 5 to the left. The use of the proposed coupling allows an increase in the speed of the connection and separation of the shafts.  In case of equal diameters of the shafts, mixing and fixing of the coupling on any of them without prior complete disassembly.
