Abstract
The utility model relates to an integral key shaft axial positioning structure, including integral key shaft, bush, transmission shaft, the integral key shaft on be provided with two external spliness to match with two epaxial internal splines of transmission that carry out the moment of torsion transmission respectively, install axial open -ended bush between two external spliness, be provided with annular constant head tank on the bush external diameter, the bush rely on constant head tank card that radial tension made its external diameter on transmission shaft end's annular table rank 6. The utility model discloses a having the breach and being equipped with the annular bush of constant head tank, the breach of bush is used for the assembly, and constant head tank in axial positioning has simple structure, and processing technology is ripe, and loading and unloading are convenient, can used repeatedly, and cost -effective characteristics.
Description
Technical field
This utility model relates to a kind of location structure, especially a kind of splined shaft axial positioning structure.
Prior art
At present, mechanically conventional spline connects and is divided into fixed and movable two kinds, and two parts of fixed connection are relatively fixed motionless, to transmit moment of torsion on axially and radially direction.Movable spline is mainly used to regulate the most not coaxial and vernier angle deviation, it is complicated to there is structure in existing movable spline axial positioning structure, the shortcomings such as manufacturing cost height, installation difficulty and bearing capacity are relatively low, it is impossible to fully meet the needs of gearing system.
Summary of the invention
The purpose of this utility model is to provide a kind of splined shaft axial positioning structure, and it is simple that this structure has manufacture process, easy for installation, and bearing capacity is big, high reliability.
Concrete technical scheme of the present utility model is, splined shaft axial positioning structure includes splined shaft, lining, power transmission shaft, external splines at two it is provided with on described splined shaft, and match with the internal spline on two power transmission shafts carrying out moment of torsion transmission respectively, being provided with the lining of axially open at two between external splines, spline axial limiting is passed through at lining two ends；Being provided with the locating slot of annular on described Outer Diameter of lining, the interior bore ends carrying out transmitting a power transmission shaft of moment of torsion is provided with ring-shaped step, and described lining relies on radial tension to make the locating slot of its external diameter be stuck on ring-shaped step.
This utility model is when mounted, first force support Large lining notch size, bushing inner diameter is made to be increased above spending strong axle external splines big footpath size, so that in the lining mounting groove that is assemblied on splined shaft of lining, force compression lining notch size again, when making Outer Diameter of lining narrow down to less than the diameter of the ring-shaped step of end part of driving shaft, and then lining and spline installation are put in place, remove external force, lining is under resilience force effect, make locating slot be stuck on the ring-shaped step of power transmission shaft, reach to limit the effect of spline axially-movable.
By there is breach and being provided with the ring bush of locating slot in this utility model, the breach of lining is used for assembling, and locating slot is in axially location.This lining uses the preferable material of pliability to make, and resilience force is big and is not likely to produce plastic deformation.This utility model simple in construction, processing technique is ripe, easy to loading and unloading, can reuse, cost-effective.
