Abstract

The invention relates to a spline pair of a hollow shaft fork. The spline pair mainly comprises a spline shaft fork and an internal splined sleeve, wherein the spline shaft fork consists of a welding fork and an external splined sleeve; the internal splined sleeve is sleeved outside the external splined sleeve and matched with the external splined sleeve; and the external splined sleeve has a hollow structure. The spline pair has the advantages that: the weight for the raw materials of the spline fork can be reduced by 37.7 percent; and after a mathematical model is established to perform static stress analysis by using CAE software, the stress is only increased by about 5 percent while the weight of the hollow spline shaft is reduced by 37.7 percent. The fact shows that the strength of the hollow spline shaft fork is substantially the same as that of a solid spline shaft fork while the weight is greatly reduced, namely the hollow spline shaft fork has higher comprehensive performance; and meanwhile, the structure ensures higher working performance for the spline pair.

Description

A kind of spline pair of hollow shaft fork
Technical field
The present invention relates generally to the spline pair field, mainly is a kind of spline pair of hollow shaft fork.
Background technique
Existing domestic comprising abroad, the composition of heavy free-sliding spline pair generally is to be matched by slip shaft yoke (external splines) and spline housing (internal spline) to form, slip shaft yoke all is solid structure, material is general to adopt solid round steel, processing technology to be generally the finish turning of blanking-forgings-ball blast-modified-slightly-mill spline-quenching etc.The slip shaft yoke stock utilization of this design and processing is 59%, and forging, modified quenching heat treatment and multiple tracks Vehicle Processing technology and external splines milling process are arranged, and energy consumption and smear metal are more, and processing cost and cost of material are higher.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of simple in structure, materials more to economize the better spline pair of hollow shaft fork of performance.
The present invention solves the technological scheme that its technical problem adopts: this spline pair of hollow shaft fork, mainly comprise slip shaft yoke and internal spline spline housing, slip shaft yoke is made up of weld yoke and external splines spline housing, the internal spline spline housing is enclosed within the outside of external splines spline housing, internal spline spline housing and external splines spline housing cooperatively interact, and the external splines spline housing is a hollow-core construction.
Described internal spline spline housing is with seal arrangement outward.
Welding is fixing between described seal arrangement and the slip shaft yoke.
Integrally welded structure between described weld yoke and the external splines spline housing.
The effect that the present invention is useful is: cutting stock weight of the present invention can alleviate 37.7%, adopts CAE software to carry out the stress at rest analysis through setting up digital-to-analogue, and hollow slip shaft yoke stress in loss of weight 37.7% only increases by 5% approximately.This shows hollow slip shaft yoke when weight alleviates greatly, and intensity and solid slip shaft yoke basically identical that is to say that treasure maesa herb key yoke is better on combination property, and simultaneously, this structure makes the service behaviour of spline pair better.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of external splines spline housing;
Fig. 3 is the structural representation of internal spline spline housing.
Description of reference numerals: slip shaft yoke 1, internal spline spline housing 2, weld yoke 3, external splines spline housing 4, seal arrangement 5.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in the figure, this spline pair of hollow shaft fork mainly comprises slip shaft yoke 1 and internal spline spline housing 2, and slip shaft yoke 1 is made up of weld yoke 3 and external splines spline housing 4, integrally welded structure between weld yoke 3 and the external splines spline housing 4.Internal spline spline housing 2 is enclosed within the outside of external splines spline housing 4, and internal spline spline housing 2 cooperatively interacts with external splines spline housing 4.External splines spline housing 4 is a hollow-core construction.Be with seal arrangement 5 outside the internal spline spline housing 2, welding is fixed between seal arrangement 5 and the slip shaft yoke 1, in order to the impurity and the dust of isolating exterior.
The present invention adopts weld yoke 3 and 4 seam of external splines spline housing to form, and weld yoke 3 adopts common forging and process for machining, and external splines spline housing 4 and internal spline spline housing 2 all adopt cold-extrusion technology.Such processing method has improved stock utilization and has reduced the technology cost.Internal spline spline housing blank and external splines spline housing blank and spline thereof adopt cold extruding formation process, belong to chipless process, and cutting stock weight greatly alleviates, and stock utilization is estimated and can be brought up to about 85%, and cancelled blank forging and modified heat treatment.External splines spline housing 4 and internal spline spline housing 2 adopt cold extrusion forming not only to reduce manufacturing procedure, shortened the process-cycle of part, when reducing cost, improved manufacturing efficiency, and cancellation is forged and modified twice highly energy-consuming has the hot procedure of pollution, can obtain tangible effects of energy saving and emission reduction.
The cutting stock weight of former solid slip shaft yoke is 22kg, finished weight is 13kg, total cutting stock weight of hollow slip shaft yoke is about 13.7kg, finished weight is about 10.07kg, cutting stock weight is estimated to alleviate 37.7% by contrast, finished weight can alleviate 22.5% approximately, but the about loss of weight 5.49kg of whole spline pair is about 28.1%.Adopt CAE software to carry out the stress at rest analysis through setting up digital-to-analogue, solid slip shaft yoke is when loading 15000N.m, the maximum stress at spline position is about 448MPa, and hollow slip shaft yoke is when loading 15000N.m, the maximum stress at spline position is about 470MPa, and hollow by contrast slip shaft yoke stress in loss of weight 37.7% only increases by 5% approximately.This shows hollow slip shaft yoke when weight alleviates greatly, and intensity and solid slip shaft yoke basically identical that is to say that treasure maesa herb key yoke is better on combination property.
In addition to the implementation, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
