Abstract

The utility model relates to a kind of gear coupling, comprises left axle sleeve and right axle sleeve.Its main points are: the left end of left axle sleeve is provided with internal spline, and right-hand member is provided with interior straight mouth; The right-hand member of right axle sleeve is provided with external splines, and left end is provided with the outer straight mouth matched with interior straight mouth; The diameter of the outer straight mouth of right axle sleeve is less than the diameter 0.02 ~ 0.05 millimeter of the interior straight mouth of left axle sleeve, and during installation, the outer straight mouth of right axle sleeve inserts in the interior straight mouth of left axle sleeve, is tightened up be integrated by lock bolt.Employing split-type structural of the present utility model, easy to manufacture, manufacturing expense is low, and do not need large processing place, machining accuracy is high; Left axle sleeve and right axle sleeve adopt straight mouth to locate, and Flange joint lock bolt tightens up, and install easy to connect, good reliability; During use, the right-hand member of right axle sleeve adopts external splines to add the axial limit structure of Steel Cable Baffle Ring, rotates torsion pass good stability, reduces the axial float of high speed rotating torsion pass, improve reliability and the working life of coupling.

Description

A kind of gear coupling
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of for transmitting large torque and high-revolving gear coupling.
Background technique
Tooth-like high-speed coupling is that one can transmitting large torque and high rotating speed, provides the driving mechanism that larger angle and radial error compensate simultaneously.This coupling axial dimension long (892mm), angle and radial error compensation effect good, be widely used in high speed torsion pass.But because this coupling axial dimension is long, during Gear Shaping, need large working space, during processing endoporus, boring bar is longer, and precision is comparatively difficult to ensure card, long processing time, and processing charges is high; Next is that this coupling left end and right-hand member are all internal splines, and left end adopts the draw-in groove axial limiting on Steel Cable Baffle Ring and internal spline, conveniently connection is installed, but the axially easy play in rotation process, affects torsion pass efficiency, also can reduce the working life of coupling.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of structure simple, easy to connect, the gear coupling that easy processing expense is low.
Gear coupling of the present utility model, comprises left axle sleeve and right axle sleeve, it is characterized in that: the left end of described left axle sleeve is provided with internal spline, and right-hand member is provided with interior straight mouth; The right-hand member of described right axle sleeve is provided with external splines, and left end is provided with the outer straight mouth matched with interior straight mouth; The outer straight mouth of right axle sleeve inserts in the interior straight mouth of left axle sleeve, is tightened up be integrated by lock bolt.
In order to better realize above-mentioned purpose:
The diameter of the outer straight mouth of described right axle sleeve is less than the diameter 0.02 ~ 0.05 millimeter of the interior straight mouth of left axle sleeve.
Gear coupling of the present utility model, adopt split-type structural, easy to manufacture, manufacturing expense is low, and do not need large processing place, machining accuracy is high; Left axle sleeve and right axle sleeve adopt straight mouth to locate, Flange joint lock bolt tightens up, install easy to connect, good reliability, during use, the right-hand member of right axle sleeve adopts external splines to add the axial limit structure of Steel Cable Baffle Ring, rotate torsion pass good stability, reduce the axial float of high speed rotating torsion pass, improve reliability and the working life of coupling.
