Description
Technical field
The utility model relates to driving-shaft assembly fields, and in particular to a kind of free-sliding spline pair disconnecting prevention structure.
Background technique
Transmission shaft is the axis that power can be transmitted in the transmission shaft of universal driving device.It is a high revolving speed, few bearing
Rotary body, therefore its dynamic balancing is vital.General transmission shaft will carry out dynamic balance running before factory, 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 within the scope of certain length free extension, become on transmission shaft to compensate input terminal and output end relative distance
The variation of overall length caused by change.Transmission shaft (especially shorter transmission shaft) is in packaging, transport, vehicle assembling process, Ke Nengfa
The accident that raw spline pair separation, i.e. slip shaft yoke part are skidded off from spline housing, is easy to pound to fall to the ground and damages product and gouge
Personnel cause security risk.Therefore a kind of novel structure is needed to improve the deficiency in existing design, avoids security risk
Occur.
Utility model content
The utility model solves above-mentioned deficiency in the prior art, provides a kind of free-sliding spline pair disconnecting prevention structure, passes through
Increase retaining member to improve the defects of existing design.Spline may occur for existing transmission shaft (especially short pass moving axis)
Pair falls off the problem of causing product gouge or personnel to damage, and prevents spline pair from falling off problem, effectively encircling spline pair, and bundle
It is easy, disassembly is simple, can also repeat binding disassembly, and do not influence transmission shaft paint appearance.
The technical scheme adopted by the utility model to solve the technical problem is as follows: this free-sliding spline pair disconnecting prevention structure, it should
Structure is made of spline pair main body, spline pair main body be successively socketed by slip shaft yoke, sealing sleeve pipe, outside framework oil seal and spline housing and
At；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 to each other to be located at sealing sleeve pipe；Band difference
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 in sealing sleeve pipe and spline housing by way of projection welding.
Band in the retaining member is nylon cable tie.
The beneficial effects of the utility model are: the utility model is compared with prior art, innovative point are as follows: 1, fixed spline
Secondary band seat and band production are simple, at low cost；2, spline pair binding is easy, and disassembly is simple, can also be repeated binding and be torn open
It unloads, and does not influence transmission shaft paint appearance.The band seat of fixation spline pair used in the utility model can be put down with existing move
The step of in the direct projection welding to transmission shaft of weighing apparatus machine, being not necessarily to extras, bundling spline pair later is easy, and disassembly is simple, can be with
Binding disassembly is repeated, and does not influence transmission shaft paint appearance, the iron wire binding method than originally generally using operates easy, shape
Beauty, it is more efficient.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
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 main body 1 by
Slip shaft yoke 2, sealing sleeve pipe 3, outside framework oil seal 4 and spline housing 5 are successively socketed to form；Anti-delinking part is installed in spline pair main body 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
With the outer surface of spline housing 5, and it is relatively parallel with the band seat 7 on spline housing 5 and correspond to each other to be located at sealing sleeve pipe 3；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 way of projection welding
On.Band 8 in the retaining member 6 is nylon cable tie.
To prevent transmission shaft spline pair free dropping (as shown in Figure 6), this reality in packaging, transport, vehicle assembling process
With one spline pair disconnecting prevention structure of new design, specific processing method is as follows: first in the close of the spline pair main body 1 of transmission shaft
Two band seats 7 (as shown in Figure 3) in horizontal symmetrical projection welding on big envelope pipe 3 and spline housing 5, then again with a nylon cable tie 8
It sequentially passes through two band seats 7 and tightens (as shown in Figure 2), transmission shaft thus can be effectively prevented and occur what spline pair fell off
Accident.The band seat 7 of spline pair main body 1 is fixed used by the utility model, band 8 makes simply, at low cost, band seat 7
Extras can be not necessarily to in the direct projection welding to transmission shaft of existing dynamic balancing machine, the binding of spline pair ontology 1 later is easy,
Disassembly is simple, can also repeat binding disassembly, and does not influence transmission shaft paint appearance, than the iron wire binding side originally generally used
Method operation is easy, and good appearance is more efficient.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
