Description

(54) CONNECTOR JOINT

one

This invention relates to units and parts of machines.

A detachable connection is known, comprising a shaft, a sleeve and intermediate elements mounted in the shaft grooves with the possibility of radial movement, interacting with grooves on the male part 1.

The disadvantage of this design is that the shaft cannot be separated from the part planted on it in the event of a sudden heating of the shaft, for example, from failure of the bearings on which the shaft rotates.

The purpose of the invention is to expand the functionality.

This goal is achieved by the fact that a detachable connection containing the female and male parts, intermediate elements installed with the possibility of radial movement in the grooves of the male part and interacting with grooves on the male part is equipped with a drive for moving intermediate elements, the intermediate elements being in the form of rectangular parallelepipeds fixed with one end of the hinge with the covered part.

and the drive, in the form of thermo-bimetallic plates, each of which is rigidly fixed to the male part, and at the other end of the intermediate element.

FIG. 1 shows the proposed connection, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node A in FIG. 1; in fig. 4 — non-operating position of the joint; in fig. 5 is a diagram of the heat supply to the thermo-bimetallic plate.

On the shaft 1 there are grooves 2 in which

10, intermediate elements 3 are installed, which can be rotated around axis 4. The intermediate element is rigidly connected to the thermobimetallic plate 5 at one end. The other end of the thermo-bimetallic plate 5 is rigidly fixed, for example using a screw 6 to the shaft 1. A sleeve 7 is mounted on the shaft; with movement. 8. The shaft 1 rotates on the bearings 9 and is made in the form of a heat pipe, the evaporator of which is located in the turning zone of the bearings 9.

Claims (2)

The node works as follows. When a subshell 9 breaks down or in the absence of lubrication, it is heated. at that, shaft 1 is heated and heat is transferred by coolant to shaft-1 assembly with part 7. Thermo-bimetallic plates 5 are heated, bent, intermediate elements 3 are retracted and removed from working position, and rotation 1 is not transferred to shaft 1 The proposed device allows the shaft to be separated from the part mounted on it, in the event of a sharp heating of the shaft, i.e. allows to expand operational capabilities. Claims 1. Split connection comprising female parts and male parts, intermediate elements installed with the possibility of radial movement 7, I-Jf T In the grooves of the male part and interacting with grooves on the male part, in order to expand its functionality, it is equipped with a drive for moving intermediate elements. 2. The connection according to claim 1, characterized in that the intermediate elements are made in the form of rectangular parallelepipeds, hinged at one end on the male part, and the drive in the form of thermo-bimetallic plates, each of which is rigidly fixed on the male part, and on the other end of intermediate element.
