Abstract
The invention relates to combination of a spline shaft and a spline sleeve, wherein a mounting blind hole of the spline sleeve consists of a spline hole and an optical hole which are of a step shape; the diameter of the optical hole is larger than the diameter of the spline hole; an annular groove is arranged on an outer spline on the end part of the spline shaft; the outer spline is divided into a front section and a rear section by the annular groove; the rear section of the outer spline is engaged with an inner spline of the mounting blind hole; and the annular groove of the outer spline is provided with an elastic clamping hoop which is axially limited by the step surface in the mounting blind hole. The combination can replace the prior welding and bolt connecting mode, ensure reliable connection between the spline shaft and the spline sleeve and meet the requirement of certain axial moving amount of the spline shaft after being assembled in place, thereby effectively preventing vibration and rupture, ensuring the transmission performance of the spline shaft and prolonging the service life. The combination is suitable for occasions where various spline shafts and spline sleeves are matched in the industries such as motorcycles, sand vehicles, automobiles and so on and is in particular suitable for the condition that welding or bolt connection can not be adopted.
Description
Technical field
The present invention relates to the axle and the fit system of axle sleeve, relate in particular to splined shaft and spline housing and make up.
Background technique
In motorcycle, beach buggy and automobile and other industries, run into the axial restraint of splined shaft and spline housing through regular meeting.Traditional mode has two kinds, and a kind of is that splined end with splined shaft stretches in the spline housing, and both are meshed, and are fixing by welding again; Another kind is that the splined end of the splined shaft end from spline housing is stretched into, and again from the other end construction bolt of spline housing, splined shaft and spline housing is tightened together.Because welding or bolt connecting mode are completely fixed splined shaft and spline housing extremely, needing splined shaft to have the occasion of certain axial mobility inapplicable like this, otherwise in the process of transmission, can have a negative impact because of vibration, rupture from weld because of vibration easily as welding manner, bolt connecting mode reduces the reliability of connection easily because of vibration, even can cause splined shaft from spline housing, to come off, greatly reduce the splined shaft stability of transmission like this, and shortened its working life.In addition, it is also inapplicable that welding or bolt are connected some specific occasions.During as special substances such as splined shaft and spline housing employing medium high carbon steel or stainless steels, be subjected to the influence of material factors, can not weld; And for example the inner splined hole of spline housing is a blind hole, and perhaps the inner splined hole of spline housing is a through hole, but when the two ends of through hole all need to insert splined shaft, all can't adopt bolt.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of splined shaft and spline housing combination, is seated the requirement that the back splined shaft has certain axial mobility to satisfy.
First kind of technological scheme of the present invention is as follows: a kind of splined shaft and spline housing combination, end at splined shaft is provided with external splines, this external splines stretches in the installing blind of spline housing, its key is: described installing blind is made up of splined hole that is positioned at the outside and the unthreaded hole that is positioned at the inboard, both are stepped shape, and the diameter of unthreaded hole is greater than the diameter of splined hole; Offer annular groove on the external splines of described splined shaft end, this annular groove is divided into forward and backward two sections with external splines, and wherein the external splines back segment is meshed with the internal spline of installing blind; In the annular groove on described external splines flexible collar is installed, this flexible collar is by the step surface axial limiting in the installing blind.
This programme makes the leading portion of splined shaft external splines and the internal spline contraposition of spline housing coincide earlier when assembling, and the external splines end of controlling splined shaft then stretches in the splined hole of spline housing, and flexible collar is shunk to the direction at its center by the compressing of spline housing hole wall; In flexible collar moves to above spline housing with splined shaft during the position of step surface, the compressing power that acts on the flexible collar disappears, flexible collar is opened under the effect of self elastic force automatically, and by the step surface axial limiting in the spline housing, this moment, splined shaft and spline housing were seated, the back segment of external splines is meshed with the internal spline of spline housing on the splined shaft, under the effect of flexible collar, splined shaft can not come off out from spline housing, and splined shaft can inwardly be done moving axially of trace with respect to spline housing, thereby has effectively reduced vibration, prevents that fracture from taking place, ensure the transmission performance of splined shaft, prolonged its working life greatly.
Above-mentioned flexible collar is the ring structure that groove is arranged, and flexible collar contracts flexibly like this, helps the assembling between splined shaft and the spline housing.
There is the oblique angle on the wheel limit of external splines leading portion end face on the splined shaft, and the oblique angle plays guiding, so that contraposition between splined shaft and the spline housing and assembling.
Second kind of technological scheme of the present invention is as follows: a kind of splined shaft and spline housing combination, end at two splined shafts is equipped with external splines, the external splines end of two splined shafts oppositely stretches in the installation through hole of spline housing, its key is: described installation through hole is stepped shape, form by splined hole that is positioned at two ends and the unthreaded hole in the middle of being positioned at, and the diameter of unthreaded hole is greater than the diameter of splined hole; Offer annular groove on the external splines of described splined shaft end, this annular groove is divided into forward and backward two sections with external splines, and wherein the external splines back segment is meshed with the internal spline that the through hole corresponding end is installed; In the annular groove on described external splines flexible collar is installed, this flexible collar is by the step surface axial limiting of installing in the through hole.
Each root splined shaft is identical with first kind of scheme with assembling and orientation type between the spline housing in this programme, under the effect of flexible collar separately, two splined shafts all can not come off out from spline housing, and two splined shafts all can inwardly be done moving axially of trace with respect to spline housing, thereby effectively reduced vibration, prevent that fracture from taking place, ensured the transmission performance of splined shaft, prolonged its working life greatly.
Beneficial effect: the present invention can replace traditional welding and bolt connecting mode, guaranteeing to be connected the while reliably between splined shaft and the spline housing, satisfied and be seated the requirement that the back splined shaft has certain axial mobility, thereby vibration and fracture have effectively been prevented, ensure the transmission performance of splined shaft, prolonged its working life greatly.The present invention have be skillfully constructed, simple in structure, implement characteristics such as easy, be applicable to the occasion that various splined shafts cooperate with spline housing in motorcycle, beach buggy, the automobile and other industries, especially can not adopt weld or bolted situation under particularly suitable.
