Description
Technical field
The utility model relates to a kind of scalable transmission shaft, especially relates to a kind of scalable transmission shaft that rolling alley spline pair is cooperated, and is specially adapted to steering axles.
Background technique
At present, the spline structure that is used for the automobile collapsible transmission shaft, generally be splined shaft and splined sleeve, splined shaft can slide in splined sleeve, and both are being slidingly matched of directly contacting, so resistance is big, quick abrasion, assembling and maintenance are relatively poor, and because of the spline of sleeve pipe and axle needs processing and required precision height separately, have increased manufacture cost.Though nylon coated is carried out on some spline fitted surface, can improve wearing and tearing, assembling and manufacture cost problem still can't solve.The patent that someone applies for " Steel ball spline (02212295.8) ", the Steel ball spline that this patent proposes are used for the binding that slides between axle and the axle sleeve.It is to be axially arranged with the gutter groove at the axle external cylindrical surface, axially also be provided with the gutter groove at the axle sleeve inner cylindrical surface accordingly, axle and axle sleeve Spielpassung, the steel ball group places the interior Steel ball spline of forming of the gutter groove of axle and axle sleeve, this structure makes axle and axle sleeve reverse mutual constraint, move axially that to change sliding friction be rolling friction, improved axially movable precision flexibility.But the displacement of the axle sleeve of this patent is not limited, and lubrication effect is very not good simultaneously; To change sliding friction be rolling friction though move axially,, use the short time, will change axle sleeve, material is made full use of.
Summary of the invention
The utility model mainly be the displacement that solves the existing in prior technology axle sleeve limit or restriction effect very not good, the while lubrication effect is very not good, the technical problem of grade easy to wear.
The utility model mainly is that solution existing in prior technology assembling is relatively poor, and maintenance is relatively poor, the technical problem that manufacture cost is more high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises splined shaft, be located at its outer retainer and spline housing, it is characterized in that being set on the retainer of plurality of rows steel ball group symmetry, the V-shaped groove on the splined shaft and the curve bath of spline housing constitute the alley of sealing; V-shaped groove two interior edge faces on the splined shaft are respectively equipped with special-shaped jump ring and common jump ring, and blanking cover is located on the splined shaft of rolling alley spline pair inboard.Splined sleeve is the cold-drawn moulding, and alley shape spline need not to carry out in addition machining, and the splined section of splined shaft only need be milled two place's V-shaped grooves, thereby has reduced manufacture cost effectively, has improved assembly performance simultaneously; V-shaped groove length on the axle is longer than retainer effective length, has effectively eliminated the steel ball unbalance stress that brings because of foozle; Along with the length difference that shaft extension contracts, retainer with adhere to it on steel ball also thereupon on V-shaped groove different position roll, thereby the steel ball unbalance stress of having avoided retainer to maintain static effectively bringing, the inconsistent problem of wearing and tearing.
As preferably, the splined section of described splined shaft is the vee-cut of two symmetries, and its length is 2-1.3 with the ratio of retainer: 1, and its two ends are provided with circular groove, and the inside of groove is provided with jump ring.V-shaped groove length on the axle is longer than the retainer effective length, has effectively eliminated the steel ball unbalance stress that brings because of foozle; And the sphere of activities of the jump ring that the two ends of groove are provided with restriction retainer.
As preferably, described spline housing inboard is laid with 12 curve baths that match with steel ball.When wherein a pair of curve bath is worn, can be transformed into another to curve bath, help making full use of material like this, save cost.
As preferably, described retainer adopts nylon to constitute, and 3-6 steel ball of every row is embedded in its both sides, and the shape of the inner face of its surface configuration and spline housing matches.Nylon has self-lubricating function; The shape of the surface configuration of retainer and the inner face of spline housing matches, and helps keeping the stability that cooperates.
As preferably, described special-shaped jump ring is a C shape, and the shape of the flange of its outer surface and spline housing inner face matches.Help keeping the stability that cooperates.
As preferably, the flange of the outer surface of described blanking cover is 6, is symmetrical distribution, matches with the shape of spline housing inner face.Flange has only 6, so promptly helps keeping the stability that cooperates, again can simplified manufacturing technique, can save the material of consumption again.
As preferably, described common jump ring is a C shape, and its external diameter is slightly larger than the diameter of splined shaft, less than the minimum diameter of spline housing inner chamber.Help limiting the moving range of retainer, and spline housing is moved freely.
Therefore, the utlity model has characteristics: 1, simple and reasonable, retainer adopts has self-lubricating function nylon formation, thereby has wear-resistant; 2, splined sleeve is the cold-drawn moulding, and alley shape spline need not processing, and the splined section of splined shaft only need be milled two place's V-shaped grooves, thereby has reduced manufacture cost effectively, has improved assembly performance simultaneously; 3, the V-shaped groove length on the axle is longer than the retainer effective length, has effectively eliminated the steel ball unbalance stress that brings because of foozle; 4, the length difference that contracts along with shaft extension, retainer with adhere to it on steel ball also thereupon on V-shaped groove different position roll, thereby the steel ball unbalance stress of having avoided retainer to maintain static effectively bringing, the inconsistent problem of wearing and tearing; 5, adopt spline fitted with low cost.
