Description
Technical field
The present invention relates to driving-shaft assembly fields, and in particular to a kind of free-sliding spline pair disconnecting prevention structure.
Background technology
Transmission shaft be universal driving device transmission shaft in be capable of the axis of passing power.It is a high rotating speed, few bearing
Rotary body, therefore its dynamic balancing is vital.General transmission shaft will carry out dynamic balance running before manufacture, and
It is adjusted on balancing machine.It is that main reducing gear is passed in the rotation of speed changer for the vehicle of preposition engine rear wheel drive
Axis, it can be several sections, can be connected by universal joint between section and section.Spline pair is the important component of transmission shaft,
Spline pair can freely stretch within the scope of certain length, become with output end relative distance to compensate input terminal on transmission shaft
Overall length caused by change changes.Transmission shaft (especially shorter transmission shaft) is in packaging, transport, vehicle assembling process, Ke Nengfa
Raw spline pair separation, i.e., the accident that slip shaft yoke part is skidded off from spline housing are easy to pound fall to the ground damage product and gouge
Personnel cause security risk.Therefore it needs a kind of novel structure to improve the deficiency in existing design, avoids security risk
Occur.
Invention content
The present invention solves above-mentioned deficiency in the prior art, provides a kind of free-sliding spline pair disconnecting prevention structure, passes through increase
Retaining member improves the defects of existing design.It is de- that spline pair may occur for existing transmission shaft (especially short pass moving axis)
The problem of causing product gouge or personnel to damage is fallen, prevents spline pair from falling off problem, effectively binds spline pair, and bundle appearance
Easily, dismounting is simple, can also repeat binding dismounting, and does not influence transmission shaft paint appearance.
The technical solution adopted by the present invention to solve the technical problems is：This free-sliding spline pair disconnecting prevention structure, the structure
It is made of spline pair main body, spline pair ontology is socketed to form successively by slip shaft yoke, sealing sleeve pipe, outside framework oil seal and spline housing；
Retaining member is installed on spline pair ontology.
The retaining member is made of band seat and band；The band seat be respectively fixedly connected in sealing sleeve pipe and
The outer surface of spline housing, and it is relatively parallel with the band seat on spline housing and correspond positioned at sealing sleeve pipe；Band is distinguished
It is tightened after the band seat being placed through in sealing sleeve pipe and spline housing.
Band seat in the retaining member is N-shaped structure, and intermediate bending part forms through-hole, and band is each passed through
It is tightened after the through-hole in sealing sleeve pipe and spline housing.
Band seat in the retaining member is fixedly connected on by the form of projection welding in sealing sleeve pipe and spline housing.
Band in the retaining member is nylon cable tie.
The beneficial effects of the invention are as follows：Compared with prior art, the present invention its innovative point is：1, the bundle of fixed spline pair
Usheing to seat, it is simple to be made with band, at low cost；2, spline pair binding is easy, and dismounting is simple, can also repeat binding dismounting, and not shadow
It rings transmission shaft and paints appearance.The band seat of fixation spline pair used in the present invention can be arrived with the direct projection welding of existing dynamic balancing machine
The step of on transmission shaft, being not necessarily to extras, bundling spline pair later is easy, and dismounting is simple, can also repeat binding dismounting, and
Transmission shaft paint appearance is not influenced, and the iron wire binding method than originally generally using operates easy, good appearance, more efficient.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As shown in the figure：This free-sliding spline pair disconnecting prevention structure, the structure are made of spline pair main body 1, spline pair ontology 1 by
Slip shaft yoke 2, sealing sleeve pipe 3, outside framework oil seal 4 and spline housing 5 are socketed to form successively；Anti-delinking part is installed on spline pair ontology 1
Part 6.The retaining member 6 is made of band seat 7 and band 8；The band seat 7 is respectively fixedly connected in sealing sleeve pipe 3
It is and relatively parallel with the band seat 7 on spline housing 5 and correspond positioned at sealing sleeve pipe 3 with the outer surface of spline housing 5；It pricks
It is tightened after being each passed through the band seat 7 in sealing sleeve pipe 3 and spline housing 5 with 8.Band seat 7 in the retaining member 6
For N-shaped structure, intermediate bending part forms through-hole, and band 8 is each passed through the through-hole in sealing sleeve pipe 3 and spline housing 5
After tighten.Band seat 7 in the retaining member 6 is fixedly connected on sealing sleeve pipe 3 and spline housing 5 by the form of projection welding
On.Band 8 in the retaining member 6 is nylon cable tie.
To prevent transmission shaft spline pair free dropping, present invention in packaging, transport, vehicle assembling process from devising one
Spline pair disconnecting prevention structure, specific processing method are as follows：First in the sealing sleeve pipe 3 and spline housing 5 of the spline pair main body 1 of transmission shaft
Two band seats 7 (as shown in Figure 3) in upper horizontal symmetrical projection welding, then sequentially pass through two bands with a nylon cable tie 8 again
Seat 7 simultaneously tightens (as shown in Figure 2), can thus effectively prevent transmission shaft that the accident that spline pair falls off occurs.Used in the present invention
Band seat 7, the band 8 of fixation spline pair main body 1 make simply, at low cost, band seat 7 can be direct with existing dynamic balancing machine
In projection welding to transmission shaft, extras are not necessarily to, the binding of spline pair ontology 1 later is easy, and dismounting is simple, can also repeat to bundle
Dismounting, and transmission shaft paint appearance is not influenced, the iron wire binding method than originally generally using operates easy, good appearance, effect
Rate higher.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
