Abstract

The invention proposes a radial disassembly coupling. A motor output shaft is connected with a transfer disc through a film coupling; the transfer disc and a middle shaft are connected through an outer sleeve; the transfer disc is contacted with a plane of the middle shaft; the outer circle parts of the transfer disc contacted with the plane of the middle shaft are symmetric conical ring surfaces; the outer sides of the two symmetric conical ring surfaces fit and are connected with inner conical ring surfaces at the two sides of the outer sleeve; the tops and the bottoms of the conical ring surfaces at the two sides of the outer sleeve are not contacted with the outer circles of the transfer disc and the middle shaft; the outer sleeve is a two-half structure, and is tightly connected through four bolts; the other end of the middle shaft and the two-half structure are connected with another transfer disc through the outer sleeve; the transfer disc extends into a test box to connect a jigger input shaft through a film coupling; and the film coupling and the jigger input shaft are connected through a locking expansion sleeve. The radial disassembly coupling is small in volume, light in weight, simple in machining and few in connecting bolts. The radial disassembly coupling is disassembled radially and is convenient for installation and disassembly.

Description

A kind of radial dismounting couplers

technical field:

The present invention relates to the engaging experimental bench field of barring gear, specifically a kind of radial dismounting couplers.

background technique:

Barring gear will carry out running adaptation before dispatching from the factory, when using conventional coupling to build pilot system, not bringing extraneous vibration when rotating for making each axle system, will look for middle work to each coupling in transmission system, this link cost manpower is many, the time is long.And after test, by barring gear remove while, the position of test motor and test chamber all will change, destroy adjusted look for middle work, like this when installing the barring gear of next same model, require a great deal of time again and repeat to look for middle work, meanwhile, when using conventional coupling, normally dismantle flange plate or diaphragm coupling, each dismounting all will be dismantled dozens of bolt, and these all substantially prolongs the test period, reduce working efficiency.

summary of the invention:

In order to shorten the cycle of the running-in of mass barring gear and the test of this type, increasing work efficiency, the invention provides a kind of radial dismounting couplers.

Technological scheme of the present invention is: a kind of radial dismounting couplers, comprise motor output shaft, motor output shaft connects transfer panel by diaphragm coupling, transfer panel is connected by overcoat with jack shaft, transfer panel contacts with neutral axis plane, the cylindrical position symmetrically cone torus that transfer panel contacts with neutral axis plane, be connected with the female cone anchor ring of the both sides of overcoat outside these two symmetrical cone torus, the top of the both sides cone torus of overcoat does not all contact with jack shaft cylindrical with transfer panel with bottom, overcoat is two halves structure, be fastenedly connected by four bolts, the other end structure same as described above of jack shaft connects another transfer panel by overcoat, this transfer panel stretches in test chamber and connects jiggering input shaft by diaphragm coupling, be connected by locking expansion set between this diaphragm coupling with jiggering input shaft.

Described overcoat is two halves structure, and after the overcoat of two halves is fastenedly connected, the end face between two halves does not contact.

The present invention has following beneficial effect: volume is little, lightweight, processing simple, attachment bolt is few and dismantled by radial direction, easy installation and removal.

accompanying drawing illustrates:

embodiment:

Below in conjunction with accompanying drawing, the invention will be further described:

Shown in Fig. 1 composition graphs 2, a kind of radial dismounting couplers, comprise motor output shaft 4, motor output shaft 4 connects transfer panel 3 by diaphragm coupling 5, transfer panel 3 is connected by overcoat 1 with jack shaft 2, transfer panel 3 and jack shaft 1 plane contact, the cylindrical position symmetrically cone torus of transfer panel 3 and jack shaft 2 plane contact, be connected with the female cone anchor ring of the both sides of overcoat 1 outside these two symmetrical cone torus, the top of the both sides cone torus of overcoat 1 does not all contact with jack shaft 2 cylindrical with transfer panel 3 with bottom, overcoat 1 is two halves structure, be fastenedly connected by four bolts, the other end structure same as described above of jack shaft 2 connects another transfer panel 3 by overcoat 1, this transfer panel 3 stretches in test chamber 8 and connects jiggering input shaft 7 by diaphragm coupling 5, be connected by locking expansion set 6 between this diaphragm coupling 5 with jiggering input shaft 7.

Described overcoat 1 is two halves structure, and after the overcoat 1 of two halves is fastenedly connected, the end face between two halves does not contact.

This coupling is divided into overcoat 1, jack shaft 2 and transfer panel 3 three parts, these three parts pass through cone match, under the effect of cover locking bolt tension force outside, the conical surface that the conical surface that the plane that transfer panel 3 coordinates with jack shaft 2, transfer panel 3 coordinate with overcoat 1, overcoat 1 coordinate with jack shaft 2 three surface of contact fluid-tight engagement, produce enough large frictional force to transmit motor and be input to moment of torsion in barring gear, meet power requirements, during Cone fit can be looked for automatically simultaneously, coupling self coaxality is better, can meet rotating accuracy requirement.

The present invention is compared with common coupling, and convenient disassembly, can shorten the test period, increase work efficiency, and its reason is as follows:

When using common coupling, after barring gear running adaptation terminates, when dismantling barring gear, because each connection place all has seam to locate, dismantle if want wherein certain a part, motor or test chamber 8 is just needed to move axially a segment distance, enable axially have certain space to be shifted out by the seam of certain end flange dish, just can pull down each several part component axially connected, like this while dismounting barring gear, just destroy the position of motor or the test chamber adjusted, when the barring gear of same model is installed again, need again to repeat loaded down with trivial details to look for middle work, simultaneously, the attachment bolt of common coupling circumferencial direction is more, the more time is all needed when dismounting and installation.

When using coupling of the present invention, when dismantling barring gear, only lock bolt need be unclamped, to dismantle overcoat 1, due to when mounted, in order to the axial thermal expansion of supplementary axle system, radial dismounting couplers two ends normally tension, when dismantling overcoat 1, axially just can produce very little space, due between jack shaft 2 with transfer panel 3 for plane coordinates, without seam, axially there is short space, just can take out jack shaft 2 by radial direction, after jack shaft 2 takes out, axially just there are enough spaces, so just can when not needing to move axially oriented motor and test chamber 8, remove the component that other axially connect, so the connection of the barring gear of next same model looks for middle work without the need to repeating again.Meanwhile, the attachment bolt of radial dismounting couplers only has 8, saves time during installation and removal.
