Abstract
The utility model relates to a mechanical driving component, particularly to a structural improvement on expansion sleeve type couplings, etc. used in generator set equipment on the rail carriages. The utility model mainly solves the technical problems existing in the prior art that the coupling with a complicated structure needs heating to work when a driving shaft is disassembled and assembled and the operation is inconvenient. The expansion sleeve coupling of the utility model comprises a coupling shaft (1) of which the surface is connected with a flange (2). The utility model is characterized in that the interior of the coupling shaft (1) is provided with a shaft sleeve (3) with a longitudinal nick. The outer surface of the shaft sleeve is provided with a taper matched with a taper arranged on the inner surface of the coupling shaft (1).
Description
Technical field
The utility model relates to a kind of mechanical transmission component, especially relates to a kind of to using the isostructural improvement of ringfeder formula coupling in passenger train generator set equipment.
Background technique
Being connected generally between the output shaft of dynamic power machine and the input shaft of work mechanism will be used coupling, realizes transferring power as the output shaft of motor and the input shaft of water pump by shaft joint.Chinese patent discloses a kind of to pin elastic coupling flexible coupling (publication number: CN 2129842Y), it comprises: a pair of master, passive half-coupling, also comprise: the straight pin that a pair of quality equates and some rubber sleeve bolts that quality is equated, wherein, the front portion of each straight pin is a conical section, and cooperate in a pair of conical butt hole that is installed in the active half-coupling symmetrically, the straight pin rear portion is cylindrical, is installed in movably in a pair of radially microscler butt hole of passive half-coupling; Each rubber sleeve bolt comprises a bolt, and fixed cover is not on this bolt and cover the rubber sleeve of the whole length of this bolt, each to the rubber sleeve bolt cooperate symmetrically in twos respectively be installed in main, passive half-coupling corresponding each in the butt hole.But the coupler structure of this structure is comparatively complicated, need heat just when the dismounting live axle and can carry out work, and is comparatively inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of ringfeder formula coupling, and it mainly is that to solve the existing in prior technology coupler structure comparatively complicated, need heat just when the dismounting live axle and can carry out work, comparatively the technical problem of inconvenience etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Ringfeder formula coupling of the present utility model comprises shaft coupling, and the shaft coupling surface is connected with flange plate, it is characterized in that described shaft coupling inside is provided with axle sleeve, and axle sleeve is provided with vertical breach, and sleeve outer surface is provided with tapering, and the tapering that its tapering and shaft coupling internal surface are provided with is complementary.Axle sleeve is provided with vertical breach, can make things convenient for it to be enclosed within on the installation shaft.Sleeve outer surface and shaft coupling internal surface are provided with the tapering that is complementary, and make shaft coupling can be installed in axle sleeve inside easily.
As preferably, the tapering that described shaft coupling internal surface and sleeve outer surface are provided with is 1: 50～1: 20.
As preferably, the tapering that described shaft coupling internal surface and sleeve outer surface are provided with is 1: 30.
As preferably, described axle sleeve outer diameter D is 90～95mm, and d is 85～90mm, and length L is 105～130mm.
As preferably, described axle sleeve outer diameter D is 90mm, and d is 85mm, and length L is 130mm.
Therefore, it is comparatively simple to the utlity model has coupler structure, does not need heating just can carry out work when the dismounting live axle, energy saving, characteristics such as dismounting is more convenient, and is rational in infrastructure.
