Abstract
The utility model relates to a compact type high-efficiency starlike sleeve for an automobile transmission shaft device. The compact type high-efficiency starlike sleeve comprises an inner circle matched with an automobile transmission shaft; six spherical faces are evenly distributed on the outer side of the inner circle; the upper plane of the inner circle is a locating datum plane; the lower plane of the spherical faces is a bottom plane; three first inner ball passages or three second inner ball passages are formed between every two spherical faces; the first inner ball passages and the second inner ball passages are distributed alternately; the first inner ball passages are spherical groove ball passages; the second inner ball passages are linear groove ball passages; the spherical groove ball passages and the linear groove ball passages are integrally formed. The compact type high-efficiency starlike sleeve has the advantages that the spherical ball passages and the linear ball passages among the six ball passages are formed in a trisection mode, the complex working conditions that the spherical ball passages can tolerate large angular displacement and the linear groove ball passages can tolerate a certain angular displacement and axial displacement are synthesized, and the two kinds of ball passages can participate in transmission compactly, efficiently and evenly at the same time.
Description
Technical field
The utility model relates to a kind of star sleeve for vehicle transmission shaft device, relates in particular to the interior alley structure of this star sleeve.
Background technique
Tradition curved grooved type transmission device, adopts initiatively fork, from parts such as moving forks; Pressure assembling, dismounting inconvenience.Owing to only having two steel ball power transmissions, when when reversion, turn to dumb, gapped, noise is large; And steel ball and curved surface groove unit pressure large, easy to wear and vibrations are large, affect physical life, be unfavorable for modern industry.
Summary of the invention
The utility model technical issues that need to address have been to provide a kind of compact high efficient rate star sleeve for vehicle transmission shaft device, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the inner circle matching with truck drive shaft; Be uniformly distributed 6 spherical shape in the outside of described inner circle; The upper plane of described inner circle is a location datum plane; The lower plane of described spherical shape is a bottom plane; Between every 2 spherical shape, form 3 the first interior alleys or 3 the second interior alleys; The first described interior alley and the second interior alley cross-distribution; Described the first interior alley is ball-type groove alley; Described the second interior alley is straight line type groove alley; Described ball-type groove alley and straight line type groove alley are formed in one.
Compared with prior art, the beneficial effects of the utility model are: due to ball-type alley in six alleys and the formation of straight line alley trisection, combine and between ball-type alley, allow the complex working condition that can simultaneously have certain angular displacement and axial displacement compared with Angular Displacement and straight line type alley, two kinds of alleys are simultaneously compact, efficiently, participate in uniformly transmission, spheroidal alley can the strain with the variation of angle, and straight line alley can axially move, save the free-sliding spline in transmission device, the needs that angle and distance change are simultaneously so just adapted to, its effect is that the angle at transmission shaft two ends equates, ensure that output equates with the instantaneous angular velocity of input shaft, therefore bearing capacity is strong, compact structure, easy accessibility, wear and tear little, life-span is grown and can be used in the steering transmission linkage of various models.

Fig. 2 is the floor map of Fig. 1.
Fig. 3 is that the A-A of Fig. 2 is to schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
From Fig. 1, Fig. 2, Fig. 3: the utility model comprises: the inner circle 1 matching with truck drive shaft; Be uniformly distributed 6 spherical shape 2 in the outside of described inner circle 1; The upper plane of described inner circle 1 is a location datum plane 3; The lower plane of described spherical shape 2 is a bottom plane 6; Between every 2 spherical shape 2, form 4 or 3 the second interior alleys 5 of 3 the first interior alleys; The first described interior alley 4 and the second interior alley 5 cross-distribution; Described the first interior alley 4 is ball-type groove alleys; Described the second interior alley 5 is straight line type groove alleys; Described ball-type groove alley and straight line type groove alley are formed in one.
In the utility model, its outer surface has six straight line type grooves parallel with axis to be connected with ball-type groove, form ball-type and the comprehensive interior alley of straight line type, six steel balls are contained in respectively in six corresponding spaces of interior alley, and are limited in same plane by ball cage.
While adopting the utility model work, power is exported by truck drive shaft, steel ball and out star wheel.Due to the angle between transmission output shaft and live axle main reducing gear input shaft with apart from changing, therefore solve with strain device, and the comprehensive interior alley that the ball-type alley of six alley trisections combines with straight line alley is the parts of realizing varied angle transmission of power, between steel ball and ball-type alley, allow compared with Angular Displacement, can eliminate driving shaft and the torsional vibration that cause asynchronous with driven shaft instantaneous angular velocity, guarantee the synchronous of diaxon rotating speed, and remaining constant speed.And pin moulding is once ground in the processing of the comprehensive interior alley that the ball-type alley of six alley trisections combines with straight line alley, in the time that rotating and have fierce impulsive load, speed change can bear compared with large contacting stress, sphere-contact has solved the pockmark that rolling causes, has peeled off and spot corrosion smoothly, and contact situation is still good.And the comprehensive interior alley structure that the ball-type alley of six alley trisections combines with straight line alley is the necessary structure in electrodeless variable-speed power transmission process, the quality of its contact stress and service behaviour directly has influence on the functional reliability of car load.And the comprehensive interior alley that the ball-type alley of six alley trisections combines with straight line alley can change the direction of transmission axis at any time, because there is the comprehensive interior alley that the ball-type alley of six alley trisections combines with straight line alley to participate in uniformly transmission simultaneously, therefore angular displacement is large, revolution, turns to nimbly and freely, bearing capacity is strong, compact structure, high efficiency, easy accessibility, wear and tear little, the life-span is grown and can be used in the automobile steering transmission device of various models.
