Abstract
The utility model discloses an involute spline sleeve of a universal drive shaft. The spline sleeve comprises a spline sleeve body, Hough centering rings and a rack roller catcher. One end of the rack roller catcher is arranged on a rack roller spindle nose. The outer edge of the body is in a regular polygon structure. One end of the rack roller catcher is in interference fit with a corresponding inner hole formed in the other end of the rack roller spindle nose, and the other end of the rack roller catcher is arranged on a spline shaft in a sleeved mode. The Hough centering rings are respectively and fixedly connected with the body and the rack roller catcher through bolts. The spline sleeve is capable of reducing abrasion of the outer edge, even though inner teeth are abraded, the spline sleeve is convenient to disassemble and replace, and therefore service life of a rack roller is greatly prolonged.
Description
Technical field
The utility model relates to spline, more particularly, relates to a kind of universal drive shaft involute splines cover.
Background technique
As everyone knows, one of characteristics of involute splines are Self-centering Action, have both made to exist the gap as the same between part is paid.But this is not necessarily correct.According to the people's such as Khaimzon data Eli, it is because the flank wearing and tearing that 80 percent spline is paid inefficacy.Tsypak points out that the fretting wear that is caused by decentraction is its main damage form.Studies show that wearing and tearing depend on design to a great extent, but to overstating there is no a criterion can be used to differentiate the flank wearing and tearing whether to occur.As a result, the pressure virtual force allowable of spline can only be reduced to quite low level.
On the other hand.Include two kinds of centering mode flank centering and diameter centering among the USS United States Standard ANSI B92.1.The artificer is often at a loss as to what to do to this.Sent diameter centering although get in ANSIB92.2, spline is available additional centering ring centering also.At this moment, the artificer can not affirm often whether this ring is essential, also needs a design criterion.
The analysis showed that further Self-centering Action just comes into force in a limited range.Can produce the centering power system of a self balancing when spline is paid stand under load, its power just with the balanced radial force this moment that acts on this pair, all teeth all are the one-side contact state with mate.After the radial force increase surpasses critical value, obvious relative displacement will appear in the center that spline is paid, and indivedual teeth will break away from mutually.If radial force continues to increase, relative displacement also continues to increase, and contact tooth progressively alkali is few, until enter bidentate side contacts state.
This involute splines is repaid has some unsatisfactory places need to improve and further improve, its outstanding shortcoming is: see also shown in Figure 1, the involute splines cover 1 direct interference of existing Universal drive shaft head is assemblied on the frame spindle nose 2, involute splined shaft 3 is subjected to the Action of Gravity Field of universal joint cross 4 in spline housing 1 internal cause, splined shaft 3 has a downward power all the time, because universal joint 4 is Arbitrary Rotation in rotary course, this can cause involute splines to overlap 1 inboard serious wear, splined shaft 3 rocks in running up and down, universal joint 4 vibration aggravations, spline housing 1 lost efficacy because of wearing and tearing.It is because flank weares and teares that 80 percent involute splines is paid inefficacy, because the fretting wear that decentraction causes is its main damage form.And at the scene in the actual using process, short working life at machine because involute tooth overlaps 1 serious wear, often be forced to by force with machine under the breast roll changing because of wearing and tearing.It is perfect that shortcoming like that is necessary that existing universal drive shaft is implemented improvement, makes it to be promoted to a kind of good equipment and product.
The model utility content
For the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of universal drive shaft involute splines cover, can reduce wearing and tearing, is convenient for changing.
For achieving the above object, the utility model adopts following technological scheme:
This universal drive shaft involute splines cover, comprise spline housing body, Hough centering ring and breast roll catcher, breast roll is taken over an end and is installed on the breast roll spindle nose, the body outer rim is the regular polygon structure, the respective interior bores interference fit that one end and the breast roll spindle nose the other end are offered, the other end is sheathed on the splined shaft, and the Hough centering ring is connected to a fixed respectively at body and breast roll catcher by bolt.
Described body outer rim is regular pentagon, regular hexagon, positive Heptagon or octagon.
The magnitude of interference of the endoporus interference fit of described body and breast roll catcher is 0.02～0.10mm.
Described breast roll takes over an end and the breast roll spindle nose is installed as interference fit.
In technique scheme, universal drive shaft involute splines cover of the present utility model comprises spline housing body, Hough centering ring and breast roll catcher, breast roll is taken over an end and is installed on the breast roll spindle nose, the body outer rim is the regular polygon structure, the respective interior bores interference fit that one end and the breast roll spindle nose the other end are offered, the other end is sheathed on the splined shaft, and the Hough centering ring is connected to a fixed respectively at body and breast roll catcher by bolt.Adopt this spline housing can reduce the wearing and tearing of its outer rim, even and odontotripsis in it, also can for convenience detachly change, thus greatly prolonged breast roll in machine working life.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 2, shown in Figure 3, universal drive shaft involute splines cover of the present utility model comprises spline housing body 11, Hough centering ring 12 and breast roll catcher 13, breast roll is taken over 13 1 ends and is installed on the breast roll spindle nose 2, body 11 outer rims are the regular polygon structure, respective interior bores 14 interference fit that one end and breast roll spindle nose 2 the other ends are offered, the other end is sheathed on the splined shaft 3, and Hough centering ring 12 is connected to a fixed respectively at body 11 and breast roll catcher 13 by bolt.Described body 11 outer rims are regular pentagon, regular hexagon, positive Heptagon or octagon, 14 of the endoporus that is octagon breast roll spindle nose 2 the other ends shown in Fig. 3 are respective shapes, and the magnitude of interference of endoporus 14 interference fit of described body 11 and breast roll catcher 13 is 0.02～0.10mm.In addition, described breast roll is taken over 13 1 ends and 2 installations of breast roll spindle nose also are interference fit.
When mounted, at first with spline housing body 11 freezing being installed in the breast roll catcher 13, the breast roll that assembles is taken over 13 interference and is assemblied on the breast roll spindle nose 2, is installed in the mill housing after a whole set of breast roll assembles, and universal joint cross 4 is installed again.Then splined shaft 3 is inserted in the spline housing body 11, finish the assembling of Universal drive spindle unit.Because body 11 outer rims and endoporus 14 are corresponding polygonal, can transmitting large torque, and by interference fit so that both without relatively moving, so both junction planes can frequently use without wearing and tearing.And when body 11 interior odontotripsis, only need 12 dismountings of Hough centering ring, with body 11 destructive remove of gas cutting with wearing and tearing, again the 11 freezing installations of new body are got final product, very convenient, thereby greatly prolonged breast roll in machine working life.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, modification.
