Abstract

The utility model relates to a shaft coupling, belonging to the technical field of transmission connectors. The utility model includes a sheath and a locating sleeve arranged inside the sheath; wherein a first coupling key and a second coupling key, which are distributed in a cross shape, are arranged into the locating sleeve, the contact surfaces of the first coupling key and the second coupling key are respectively provided with a notch, and the notches of the two coupling keys are connected with each other by means of a socket joint. The utility model has the advantages of simple structure, convenient installation, relatively large carrying capacity, relatively low assembly cost, and low requirement for the proper alignment of the two coupling shafts, solving the problem that the prior art has a relatively low carrying capacity, that the connection with the shaft coupling is difficult after the spring pins are fixed at the shaft ends, and that meantime the relatively high requirement for the proper alignment of the two coupling shafts leads to an increased assembly cost.

Description

Coupling

Technical field

The utility model relates to a kind of coupling, belongs to the technical field of transmission joint part.

Technical background

Common coupling adopts plastic casing, middle no linking bond, and bearing capacity is relatively poor, is connected with coupling behind the axle head installation resilient key, installs cumbersomely, simultaneously the coaxality of two joining shafts is had relatively high expectations, and has caused the raising of assembly cost.

Summary of the invention

It is a kind of simple in structure that the utility model purpose is to provide, easy for installation, bearing capacity is bigger, assembly cost is lower, and to the lower coupling of coaxality requirement of two joining shafts, the bearing capacity that has solved the prior art existence is relatively poor, axle head is connected with coupling after resilient key is installed, install cumbersomely, simultaneously the coaxality of two joining shafts is had relatively high expectations, caused the problems such as raising of assembly cost.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise and expand cover and be located at the interior setting sleeve of sheath, be provided with in the described setting sleeve and be first linking bond and second linking bond that criss-crossing is arranged mutually, be respectively equipped with groove on the surface of contact of described first linking bond and second linking bond, the groove of two linking bonds is plugged on together mutually.Adopting coupling of the present utility model only to need to open a groove at axle head can install, and easy installation and reliable, two linking bonds are plugged on the bearing capacity that has improved coupling together greatly by groove; Outer surface covers with sheath, prevents the setting sleeve stress deformation, increases the coupling bearing capacity.

As preferably, described setting sleeve is a rubber sleeve, and described rubber sleeve is the one injection structure with first linking bond and second linking bond, and the rubber sleeve two ends are fixed in riveting in the described sheath two ends.Wherein, setting sleeve adopts the rubber sleeve structure, has buffer function when connecting two parts, has reduced the coaxality requirement of two joining shafts, saves assembly cost.

Therefore, the utlity model has simple in structurely, easy for installation, bearing capacity is bigger, and assembly cost is lower, and the coaxality of two joining shafts is required characteristics such as lower.
