Abstract
The utility model relates to an inner ball cage with a bearing, which comprises a bell housing and an assembly. The inner ball cage is characterized in that a chamfer is arranged at the position of an opening on the inner wall of the bell housing, and an inward portion at the position of the opening on the inner wall of the bell housing of the inner ball cage is parallel to a center shaft of the inner ball cage. The assembly is capable of axially and freely moving in the bell housing, and enabling an input shaft and an output shaft to be changed not only in axial angle, but also in axial spacing, thereby enabling the input shaft and the output shaft to be adapted to axial displacement of a power output part and a power input part. Besides, the arrangement of the chamfer brings convenience for the output shaft to flexibly transfer torque.
Description
Technical field
The utility model relates to a kind of transmission device, and the universal joint that relates in particular to automobile holds internal spherical cage with tape spool.
Background technique
For making the automobile power transmission, no matter be forerunner or rear-guard, or use independent suspension, all can use universal joint, what employing was maximum at present is rzeppa universal joint, all solved constant speed transmission problem preferably no matter this kind universal joint is circular arc alley or liner ball road, and it is big to transmit operating angle, the efficient height.But automobile on the way travels, the situation of running into is quite complicated, universal joint as actuating unit not only needs working stability, efficient height, also need to adapt to more complicated transmission situation, present universal joint can only make universal joint do certain change on driving angle with the ball cage, can not adapt to more complicated situation.
The model utility content
The purpose of this utility model provides a kind of working stability, efficient height, effective, transmission version universal joint internal spherical cage how.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: the internal spherical cage that a kind of tape spool holds, comprise outer race, assembly, it is characterized in that: described outer race inwall opening is provided with chamfering, and inside part of the opening of internal spherical cage outer race inwall and internal spherical cage central axes.Assembly can make input shaft and output shaft not only at axial angle certain change be arranged at the outer race axial free movement, also can make distance between shafts also do certain change, to adapt to the situation that power output part and power input part axially are subjected to displacement; Being provided with of chamfering makes things convenient for output shaft flexible communication moment of torsion.
As preferably, described assembly comprises three balls, retainer and star sleeves, and described star sleeve outer surface is provided with three grooves, and described outer race internal surface is provided with three grooves.Three balls and three grooves can make torque drive reach effect preferably, and quantity reduces then transmission position stress ability to bear deficiency, than fragile under the high pulling torque; Quantity reduces, and the size of then corresponding ball and groove is inevitable also to be reduced, and has reduced the stress ability to bear at transmission position equally.
As preferably, described outer race rear portion is provided with transmission shaft, and described transmission shaft is provided with ball bearing.
In sum, the utlity model has following beneficial effect:
1, assembly can be done axial motion in outer race, makes not only can change axial angle between power input shaft and the output shaft, can also do the change of axle base within the specific limits, makes more complicated situation of universal energy-conservation adaptation;
2, the Rzeppa type structure makes that the transmission of universal joint constant speed is effective, the transmission operating angle is big, efficient is high, and bearing capacity is strong.
Description of drawings
Fig. 1 is the utility model anatomical structure figure;
Among the figure, 1, outer race, 2, assembly, 3, bearing, 4, circlip for shaft, 5, guard ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Embodiment 1
As shown in the figure, a kind of built-in type internal spherical cage comprises outer race 1, assembly 2, and described outer race 1 inwall and outer race central axes are provided with three grooves, and the internal surface opening is provided with chamfering, and outer race 1 rear portion also is provided with input shaft; Described assembly 2 can be made axial free movement in described outer race 1 inside, is provided with three balls in the described assembly 2, is loaded in three grooves of outer race 1 internal surface.Input shaft is provided with bearing 3 and two guard rings 5, also is provided with circlip for shaft 4 between bearing 3 and the guard ring 5.
During work, line shaft fixedly is loaded on the input shaft at outer race 1 rear portion, the assembly 2 center fixation pto of packing into, bearing 3 fixedly is loaded on the support; When input shaft rotates, drive outer race 1 and make same angular velocity and rotate, because the screens of three grooves and spin, assembly 2 drives output shafts and makes same angular velocity and rotate, and finishes the transmission of power.Assembly 2 can be done unrestricted motion at outer race 1 inner surface axial, so the angle between output shaft and the input shaft and spacing all can change.
Claims (3)
1. the internal spherical cage that tape spool holds comprises outer race, assembly, it is characterized in that: described outer race inwall opening is provided with chamfering, and inside part of the opening of internal spherical cage outer race inwall and internal spherical cage central axes.
