Abstract
The invention belongs to the vehicle drive fitting technical field, and provides an improved ball cage triaene assembly comprising a triaene and rollers; the triaene is provided three rolling columns; an outer ring of each of the three rolling column is sleeved with the roller; a whole shape of the rolling column is in a ball shape; two sides of the rolling column are respectively provided with an abut joint surface in clearance fit with the roller and in joint contact, wherein the abut joint surface and the roller are in point-surface contact. The advantages are that the rolling column matching the triaena with the roller is changed into a ball cylinder from an original cylinder, so an original surface-surface contact is changed into point-surface contact, thus enlarging a swing angle when the triaene and the rollers rotate, increasing bearing force, and ensuring running stability; in addition, the roller is changed into an outer ring body, an inner ring body and a needle roller body from original outer ring body and needle roller body, thus further ensuring rotation, and ensuring always tight contact in swing, and preventing shaking in work.
Description
Technical field
The invention belongs to Automobile drive accessory technical field, relate to a kind of ball cage trident assembly of improvement.
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, moved in chute by rotary bearing, the angle that ball cage rotates is less simultaneously, and triaene touch scrolling is cylindrical body contact, and cause pivot angle less like this, bearing capacity is poor, is difficult to the stability ensureing to run.
Summary of the invention
Technical problem to be solved by this invention is the present situation for prior art, and provides a kind of pivot angle large, and bearing capacity is better, the ball cage trident assembly of the improvement of working efficiency height assembly operation stability.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of ball cage trident assembly of improvement, comprise triaene and roller, described triaene is provided with three rolling posts, sheathed roller on rolling post outer ring described in three, it is characterized in that, described rolling post monnolithic case is spheroid, all having in rolling post both sides conflicts with roller phase Spielpassung fit abut face, described abutting face contacts for putting a face with roller.
Here the maximum improvements of the present invention are changed the shape of rolling post, here existing rolling post is in cylinder type, like this with during roller contact be face, face Structure deformation, when causing swing, pivot angle is too small, and the present invention due to rolling post be in spheroid structure, and the abutting of the spheroid of both sides face is just the tangent point position of cambered surface, and such rolling post and roller contact in the face of putting exactly, whole pivot angle is increased, thus increases bearing capacity.
The measure taked for optimizing such scheme specifically comprises:
At the ball cage trident assembly of above-mentioned a kind of improvement, described roller comprises inner ring body and outer ring body, be provided with needle roller body between described inner ring body and outer ring body, described inner ring body abuts face Spielpassung with rolling post outer ring, and described abutting face and inner ring body are that a some face contacts.Here roller is become outer ring body, inner ring body and needle roller body structure by outer ring body before with needle roller structural reform simultaneously, further ensure swing rotary smooth and easy, tight conflict can be ensure that all the time when swinging, avoiding producing at work rocking, ensure that the stability of work.
At the ball cage trident assembly of above-mentioned a kind of improvement, described inner ring body and needle roller body and outer ring body and needle roller body are plane-plane contact.
At the ball cage trident assembly of above-mentioned a kind of improvement, the both sides up and down of described outer ring body are all provided with back-up ring, and described back-up ring abuts in the two ends up and down of needle roller body and is sealed between inner ring body and outer ring body by needle roller body.
At the ball cage trident assembly of above-mentioned a kind of improvement, the both sides, joint of described triaene and rolling post are provided with indent rounding groove.Here indent rounding groove makes whole rolling post be spheroid shape, prevents roller from interfering with triaene when swinging.
At the ball cage trident assembly of above-mentioned a kind of improvement, described abutting face is less than φ 0.04mm with the matching gap size of inner ring body.
At the ball cage trident assembly of above-mentioned a kind of improvement, after described roller coordinates with triaene, there is pivot angle, described pivot angle angle >=26 °.
Compared with prior art, the invention has the advantages that the rolling post coordinated with roller by triaene has made spherocylinder into by original cylindrical body, make to have made some face into by original plane-plane contact like this to contact, when triaene and roller are rotated, pivot angle increases, increase bearing capacity, ensure the stability run, roller is become outer ring body, inner ring body and needle roller body structure by outer ring body before with needle roller structural reform simultaneously, further ensure rotation, all the time ensure that tight conflict when swinging, avoiding producing at work rocking.
