Description
Technical field
The utility model belongs to Automobile drive accessory technical field, is related to a kind of external ball cage rotation control means.
Background technology
In order that automobile power transmission, can use and arrive driving axis, it is at most ball cage type drive axle to use at present
Assembly, whether circular arc alley or liner ball road all preferably solve the problems, such as constant speed drive to such a driving axis, and pass
It is big to pass operating angle, efficiency high.The shortcomings that existing external ball cage is that whole housing inner structure setting is unreasonable, causes automobile turning
During, Rzeppa constant velocity joint dust cover failure caused by dust cover caused by pivot angle is excessive is interfered with connection cover is asked
Topic, brings certain potential safety hazard in the process of moving.
The content of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and offer is a kind of simple in construction,
Closure is good, ensures the external ball cage rotation control means of driving axis operation stability.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of external ball cage rotation control means,
Including bell housing, input shaft and the retainer being arranged in bell housing, steel ball and inner race, described input shaft is set
Orbit rotation of the retainer in inner race can be passed through in one end of bell housing, described steel ball by putting, it is characterised in that institute
Rotation control means are offered on the inner surface for the bell housing stated, described rotation control means include arc surface, directly to face
And corner surface, described arc surface are in contact with the surface of steel ball, the junction in face and corner surface is directly provided with pad lid, in institute
The right-hand end for the retainer stated has junction in width along in place, and the left-hand end of described retainer has short interior junction along in place.
The measure taken for optimization such scheme specifically includes：
In a kind of above-mentioned external ball cage rotation control means, the bell housing inner surface is provided with groove, the groove
Positioned at clutch can and steel ball contact site, it is circular arc chamfering with bell housing inner surface connecting portion.
In a kind of above-mentioned external ball cage rotation control means, connecting hole is longitudinally offered on described input shaft, defeated
Enter and spline is provided with the inner side of axle.
In a kind of above-mentioned external ball cage rotation control means, described inner race, retainer and steel ball are in clutch can
Internal axial string momentum is less than 0.2mm.
Compared with prior art, the utility model has the advantage of by directly can be to external ball cage corner to face and corner surface
Rotation limitation is carried out, solves the dust cover Problem of Failure caused by pivot angle is excessive, is kept here by increasing the end with junction in width
The sphere-contact area and effective thickness of frame, make its bearing capacity improve significantly, and impact resistance, set again short interior junction cause by
Power is smaller, can smoothly be assembled especially for inner race is made.
Brief description of the drawings
Fig. 1 is this external ball cage rotation control means schematic diagram.
Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
In figure, bell housing 1；Input shaft 2；Retainer 3；Steel ball 4；Inner race 5；Arc surface 6；Directly to face 7；Corner surface 8；
Wide interior junction 9；Short interior junction 10；Groove 11；Connecting hole 12；Spline 13.
As shown in figure 1, this external ball cage rotation control means, including bell housing 1, input shaft 2 and it is arranged on clutch can
Retainer 3 in body 1, steel ball 4 and inner race 5, input shaft 2 are arranged on one end of bell housing 1, and steel ball 4 can pass through guarantor
Orbit rotation of the frame 3 in inner race 5 is held, rotation control means, rotation control means are offered on the inner surface of bell housing 1
Including arc surface 6, directly it is in contact to face 7 and corner surface 8, arc surface 6 with the surface of steel ball 4, directly to face 7 and the company of corner surface 8
The place of connecing is provided with pad lid, has wide interior junction 9 along in place in the right-hand end of retainer 3, the left-hand end of retainer 3 has along in place
Short interior junction 10, here by the way that directly rotation limitation can be carried out to external ball cage corner to face 7 and corner surface 8, solve because of pivot angle mistake
Dust cover Problem of Failure is caused greatly, here by increasing the sphere-contact area of the end retainer 3 and effective wall with wide interior junction 9
Thickness, its bearing capacity is improved significantly, and impact resistance, set short interior junction 10 make it that stress is smaller again, especially for making star
Set 5 can be assembled smoothly.
The inner surface of bell housing 1 is provided with groove 11, and the groove 11 is located at clutch can and the contact site of steel ball 4, itself and clock
The inner surface connecting portion of shape housing 1 is circular arc chamfering, improves the lubricant effect between bell housing 1 and steel ball 4 here, can also
Hard impurity is collected wherein, abrasion is further reduced, improves the service life of external ball cage, longitudinally opened on input shaft 2
Provided with connecting hole 12, spline 13 is provided with the inner side of input shaft 2, is conveniently attached by connecting hole 12 here, spline
13 improve bearing capacity.Inner race 5, the axial string momentum of retainer 3 and steel ball 4 in bell housing 1 are less than 0.2mm.
