Abstract
The utility model belongs to the technical field of car drive accessory, a interior ball cage trident assembly structure is provided, including main part and three gyro wheel, be provided with three rolling column in the main part, on the outer circular surface of three rolling column evenly distributed in the main part, three roller housing still is provided with the kingpin body, the last jump ring that still is provided with of rolling column between gyro wheel and the rolling column on three rolling column. The utility model has the advantages of the kingpin body and jump ring have not only been protected through the retaining ring simultaneously to the rotatory dynamics of the gyro wheel through jump ring increase, have increased the bearing capacity, guarantee the stability of operation, have further guaranteed the rotation, use surface to surface contact when the swing, have guaranteed inseparable conflict all the time, avoid production at work to rock.
Description
Technical field
The utility model belongs to Automobile drive accessory technical field, relates to a kind of internal spherical cage trident assembly structure.
Background technique
In order to make automobile power transmission, all driving axis can be used, what current employing was maximum is Rzeppa type driving axis, no matter this kind of driving axis is that circular arc alley or liner ball road solve constant speed drive's problem all preferably, and it is large to transmit operating angle, efficiency is high, high performance Rzeppa type driving axis is except requiring stably except transferring power, also have intensity reliable, pivot angle requires large, long-lived requirement, existing internal spherical cage mainly comprises triadius type and six bead, the constant velocity driving shaft internal spherical cage used in the market comprises bell shell and is set in the trident bearing in bell shell, by trident bearing slippage or rotation in the chute of bell shell, realize the gearing of internal spherical cage, the constant velocity driving shaft internal spherical cage of transmission is rotating speed is comparatively large or corner is larger, trident bearing and bell shell collide, easily cause damage, change cumbersome, its cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of pivot angle large, and bearing capacity is better, the internal spherical cage trident assembly structure of working efficiency height assembly operation stability.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of internal spherical cage trident assembly structure, comprise main body and three rollers, described main body is provided with three rolling posts, three described rolling posts are evenly distributed on the outer ring face of main body, three described roller housings are on three rolling posts, it is characterized in that, between described roller and rolling post, be also provided with needle roller body, described rolling post is also provided with jump ring.
The measure taked for optimizing such scheme specifically comprises:
In above-mentioned a kind of internal spherical cage trident assembly structure, be also provided with back-up ring between the upper-end surface of described rolling element and needle roller body, described back-up ring is in the upper end of needle roller body and be sealed between roller and rolling post by needle roller body.Here back-up ring so just makes needle roller body just be in closed space, prevents other impurity from entering in needle roller body, prevents from interfering with swing, and back-up ring, once assembling, must not come off.
In above-mentioned a kind of internal spherical cage trident assembly structure, described back-up ring envelopes jump ring from away from rolling post.So just jump ring and outside are isolated, prevent impurity from entering into the work of internal influence jump ring.
In above-mentioned a kind of internal spherical cage trident assembly structure, being plane-plane contact between described rolling post and needle roller body, is also plane-plane contact between described needle roller body and roller.After such assembling, ensure that roller slippage and pivot angle nimbly and freely, make roller with between coordinate after pivot angle increases, increase bearing capacity, ensure operation stability.
In above-mentioned a kind of internal spherical cage trident assembly structure, the upper end edge of described roller is lower than back-up ring place plane.Make roller more flexible when rolling like this.
Compared with prior art; the utility model has the advantage of the rotation dynamics of the roller increased by jump ring; not only protect needle roller body and jump ring by back-up ring simultaneously; increase bearing capacity; ensureing the stability run, further ensure rotation, using plane-plane contact when swinging; all the time ensure that tight conflict, avoid producing at work rocking.
Accompanying drawing explanation
Fig. 1 is this internal spherical cage trident assembly structure schematic diagram.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
In figure, main body 1; Roller 2; Rolling post 3; Needle roller body 4; Jump ring 5; Back-up ring 6.
As shown in Figure 1, this internal spherical cage trident assembly structure, comprise main body 1 and three rollers 2, main body 1 is provided with three rolling posts 3, three rolling posts 3 are evenly distributed on the outer ring face of main body 1, three rollers 2 are enclosed within three rolling posts 3, needle roller body 4 is also provided with between roller 2 and rolling post 3, rolling post 3 is also provided with jump ring 5, the rotation dynamics of the roller 2 increased by jump ring 5 here, back-up ring 6 is also provided with between the upper-end surface of rolling element 3 and needle roller body 4, the upper end edge of roller 2 is lower than back-up ring 6 place plane, make roller 2 more flexible when rolling like this, back-up ring 6 is in the upper end of needle roller body 4 and be sealed between roller 2 and rolling post 3 by needle roller body 4, here back-up ring 6 just makes needle roller body 4 just be in closed space like this, prevent other impurity from entering in needle roller body 4, prevent from interfering with swing, back-up ring 6 is once assembling, must not come off, back-up ring 6 envelopes jump ring 5 from away from rolling post 3, is so just isolated in jump ring 5 and outside, prevents impurity from entering into internal influence jump ring 5 and work, being plane-plane contact between rolling post 3 and needle roller body 4, is also plane-plane contact between needle roller body 4 and roller 2, like this after assembling, ensure that roller 2 slippage and pivot angle nimbly and freely, make roller 2 with between coordinate after pivot angle increases, increase bearing capacity, ensure operation stability.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from the scope that spirit of the present utility model defines.
