Abstract
The invention relates to a spline shaft axial locating structure. The spline shaft axial locating structure comprises a spline shaft, a bushing and transmission shafts. The spline shaft is provided with two outer splines which are matched with inner splines on the two transmission shafts correspondingly. The two transmission shafts conduct torque transmission. The bushing with an axial opening is installed between the two outer splines. The outer diameter of the bushing is provided with an annular locating groove. According to the bushing, the locating groove in the outer diameter of the bushing is clamped on an annular step 6 at the end of one transmission shaft through radial tension. According to the spline shaft axial locating structure, the annular bushing is provided with a notch and the locating groove, the notch of the bushing is used for assembly, and the locating groove is used for axial locating. The spline shaft axial locating structure has the characteristics of being simple in structure, mature in machining process, convenient to assemble and disassemble, and capable of being reused and reducing cost.
Description
Technical field
The present invention 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 on axially and radially direction, to transmit moment of torsion.Movable spline is mainly used to regulate radially, axially not coaxial and vernier angle deviation, there is structure complexity 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
It is an object of the invention to provide a kind of splined shaft axial positioning structure, it is simple that this structure has manufacture process, easy for installation, and bearing capacity is big, high reliability.
The concrete technical scheme of the present invention is, splined shaft axial positioning structure includes splined shaft, lining, power transmission shaft, described splined shaft is provided with two place's external splines, 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 between two place's 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 a power transmission shaft of transmission 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.
The present invention 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 lining is assemblied in the lining mounting groove on splined shaft, 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 the effect of restriction spline axially-movable.
By there is breach and being provided with the ring bush of locating slot in the present invention, the breach of lining is used for assembling, and locating slot is in axial location.This lining adopts the good material of pliability to make, and resilience force is big and is not likely to produce plastic deformation.Present configuration is simple, and processing technique is ripe, easy to loading and unloading, it is possible to reuse, and saves cost.
