Abstract

The utility model provides an elastic sleeve column pin coupler, belongs to the mechanical transmission field, and characterized by has flange, outer wall to have the pipy withdrawal of the awl that cracks cover suit in driven end half coupling's conical column pinhole for conical axial system main aspects system, and the elastic sleeve suit of suit on the pin cylindrical section stops that the retaining ring of elastic sleeve roll -off is installed in the ring channel of pin tip in the withdrawal cover, and the arc clamp plate that stops withdrawal cover roll -off passes through the fix with screw on driven end half coupling's terminal surface, the utility model has the advantages that easy dismounting, the centering precision of shaft coupling is high.

Description

A kind of rubbercushioned sleeve bearing coupling

Technical field

This utility model belongs to mechanical transmission fields, is specifically related to a kind of rubbercushioned sleeve bearing coupling.

Background technology

Shaft coupling is for connection to the driving shaft in different institutions with driven shaft so as to jointly rotate the parts to transmit moment of torsion.

Being illustrated in figure 1 prior art rubbercushioned sleeve bearing coupling, resilient sleeve therein is generally rubber, has a definite limitation service life, it is necessary to periodic replacement.When changing resilient sleeve, it is necessary to pulled down from drive end half a coupler by pin, the faying face of pin and drive end half a coupler is conical bore, and pin needs certain strength strike just to can be taken off when pulling down, it is easy to causes pin threaded portion impaired and scraps.It is said that in general, what pin was usually scrapped by strike in unloading process.Patent CN200720068981 provides the improved method of a kind of shaft coupling, in the Partner column pin hole of shaft coupling, have circlip slot, groove is provided with back-up ring, eliminate the shaft shoulder of pin end, during dismounting, it is possible to realize changing the purpose of resilient sleeve when not dismantling pin by removing column pin hole Elastic back-up ring.But this patent has the drawback that in actual operation, due to the restriction of work space, resilient sleeve is difficult to take out from column pin hole, generally requires some apparatuses, and just can be taken off sometimes for passing through further resilient sleeve of destroying, causes waste.

Summary of the invention

This utility model purpose is to provide a kind of rubbercushioned sleeve bearing coupling, the shortcoming that can exist efficiently against prior art.

This utility model is achieved in that such as Fig. 2, shown in 3, it includes drive end half-coupling 1, driven end half-coupling 2, pin 3, resilient sleeve 4, withdrawal sleeve 5, arc pressuring plate 6 and back-up ring 7.Driving and driven half-coupling 1,2 is connected by n resilient sleeve and pin, n is positive integer, resilient sleeve and pin connection are characterized by that the resilient sleeve 4 being sleeved on pin 3 cylindrical section is sleeved in withdrawal sleeve 5 by end is shaped with flange greatly, outer wall is that conical shaft is sleeved in the tapered pole pin-and-hole of driven end half-coupling 2 to the withdrawal sleeve 5 being shaped with the Taper Pipe shape cracked；Stop that the back-up ring 7 that resilient sleeve 4 skids off is arranged in the cannelure (301) of pin 3 end；Stopping that the arc pressuring plate 6 that withdrawal sleeve 5 skids off is fixed on the end face of driven end half-coupling 2 by screw 8, the outer wall tapering of described withdrawal sleeve 5 is 6 ~ 9 degree.

Advantage of the present utility model and have the benefit effect that when not dismantling pin, replaceable, dismounting resilient sleeve, taper design is prone to dismounting.While compressing withdrawal sleeve, the enclasping force that withdrawal sleeve produces due to deformation, considerably increase the centering precision of rubbercushioned sleeve bearing coupling.

Detailed description of the invention

As shown in Figure 2,3, during assembling shaft coupling, first the small end of pin 3 is loaded in the connecting hole of drive end half-coupling 1, it is bolted, again driven end half-coupling 2 is sleeved on the cylindrical section of pin 3 by column pin hole thereon, again withdrawal sleeve 5 is sleeved in driven end half-coupling 2 column pin hole, again resilient sleeve 4 is sleeved on the cylindrical section of pin 3, again back-up ring 7 is arranged in the end cannelure 301 of pin 3, then arc pressuring plate 6 is fixed on the end face of driven end half-coupling 2 by screw 8.During dismounting, reverse operating.Advantage is: can dismantle pin, can resilient sleeve quickly be dismantled, and the design of taper feature improves the centering precision of rubbercushioned sleeve bearing coupling simultaneously.
