Description

A kind of technological equipment of concertina type universal joint of the assembly with oblique angle type alley

Technical field

The utility model relates to a kind of technological equipment for assembling constant velocity driving shaft, in particular to a kind of assembly has oblique angle type The technological equipment of the concertina type universal joint of alley.

Background technique

Constant velocity driving shaft is the axis connection that two axis are not overlapped, and keeps two axis dynamic with the transmitting of identical angular speed The mechanism of power, effect are that power of engine is delivered from speed changer to automotive wheels, while meeting vehicular transmission shaft outer end and turning The requirement at angle.

Constant velocity driving shaft includes the first universal joint for being mounted on road wheel end, jackshaft and is mounted on the 20000th of gearbox end Xiang Jie, jackshaft both ends are connected with the first universal joint and the second universal joint respectively；First universal joint is in order to adapt to wheel steering angle It needs, usually fixed ball-type rotational structure, referred to as fixed knot；Second universal joint is generally for the axis for adapting to constant velocity driving shaft Change to length, setting can axially extending and rotation mobile model structure, referred to as movable joint.

Movable joint includes foreign steamer and lubrication groove, and foreign steamer inner surface is equipped with outer alley, and lubrication groove is socketed in foreign steamer, and lubrication groove is along axial Equipped with axis hole, the jackshaft is socketed in axis hole, and the outer surface of lubrication groove is equipped with the interior alley corresponding to outer alley, an ectosphere Road and an interior alley constitute a complete alley, and ball moves, and will start in alley under the constraint of alley The torque of machine passes to jackshaft；Retainer is additionally provided between foreign steamer and lubrication groove, retainer is annular, is kept for mounting ring week be equipped with and passed through The ball hole of logical retainer side wall, ball is in ball hole.

There are two types of forms for alley in concertina type universal joint, and one is run-in index alleys, i.e. the axis phase of alley and lubrication groove In parallel；Second is oblique angle type alley, i.e., the inclined direction between two adjacent interior alleys of lubrication groove is on the contrary, constitute " V " shape cloth Office, between two adjacent adjacent outer alleys of foreign steamer also inclined direction on the contrary, and the outer alley of same alley and interior It is to intersect between alley relatively, the center line of interior alley and outer alley all keeps an inclined angle with the axis of lubrication groove, Ball in alley always on the crosspoint in interior alley and outer alley, the concertina type universal joint of this oblique angle type alley also by Referred to as VL type universal joint；VL type universal joint transmitting power is steady, high-efficient, is widely used.

For VL type universal joint in assembly, only one optimal axial position is poor between foreign steamer, lubrication groove and ball, when outer When wheel, lubrication groove and ball are in this alternate position spike, foreign steamer successfully can axially be socketed lubrication groove, ball, when being in other positions, Each component assembling will form biggish interference, not only influence assembly efficiency, be also easy to cause the damage of alley and ball.

Utility model content

The utility model is that have oblique angle type alley by providing a kind of assemble to overcome above-mentioned defect in the prior art Concertina type universal joint technological equipment, to the maximum extent reduce assembling process in ball and alley damage, and improve this ten thousand To the assembly efficiency of section.

To achieve the above object, the utility model provides a kind of work of concertina type universal joint of the assembly with oblique angle type alley Skill equipment, wherein including lubrication groove reference seat, retainer reference seat；Lubrication groove reference seat is equipped with lubrication groove against benchmark, one end of lubrication groove Face is connected to the lubrication groove on benchmark, and keeps abutting and stablize；Retainer reference seat is looped around the outer of lubrication groove reference seat Portion, retainer reference seat are equipped with retainer benchmark, and an end face of retainer is connected on the retainer benchmark, and keep supporting Connect stabilization；Ball is embedded in the interior alley of lubrication groove in the ball retaining hole of retainer；Retainer benchmark is in lubrication groove It is higher than when lubrication groove is assembled against benchmark, the difference in height of the two and the concertina type universal joint of oblique angle type alley in axial direction in ball insertion The optimum height position of alley is corresponding, and foreign steamer is from outside socket ball, retainer and lubrication groove when assembly, and ball is embedded at this time The best socket position of outer alley and interior alley, axial to push foreign steamer, ball is met along outer alley to foreign steamer, and passes through interior alley It drives lubrication groove to meet to foreign steamer and completes socket assembly, this technological equipment can will drop to the damage of alley and ball in assembling process It is minimum, while improving the efficiency of assembly.

Preferably, also around ball support ring is equipped with, ball support ring is equipped with and rolling in the outside of the retainer reference seat The ball supporting surface that pearl abuts against, ball support ring along the axial direction of retainer or lubrication groove make it is reducible move, outside wheel socket Before lubrication groove, ball support ring is in initial position, and ball supporting surface carries out abutting support to ball, prevents ball from keeping from ball Deviate from hole；Wheel socket retainer and when lubrication groove outside, foreign steamer compressing ball support ring move down simultaneously and with ball be separated to It connects, outer alley constrains ball at this time, it is no longer necessary to which ball support ring prevents ball from deviating from from retainer；In socket After the completion of the operation of wheel and foreign steamer, when taking out the complete lubrication groove of connection, retainer and foreign steamer, ball support ring is reset to initial bit It sets.

Preferably, the retainer reference seat be axially through ring structure, lubrication groove reference seat be cylindrical structure, Lubrication groove reference seat adaptation is socketed in the inner hole that retainer reference seat is penetrated through so that retainer reference seat and lubrication groove reference seat it Between connect easy, and manufacturing process is easy.
