Description
Technical field
The utility model relates to a kind of thrust-bearing nylon split retainer, belongs to the thrust-bearing technical field.
Background technique
The thrust-bearing that is used in the vehicle gearbox is installed between driving gear and the transmission shaft usually.Thrust-bearing mainly is made of retainer and roller and bearing inner race or bearing outer ring, retainer is made of in uniform some pockets hole in the circumferential direction of the circle annular frame and annular frame, roller is installed in each pocket hole, contact with transmission shaft with driving gear respectively by roller, or bearing inner race is connected with retainer, bearing inner race is installed on the transmission shaft, and bearing outer ring is installed in the mounting hole of driving gear.Common retainer is overall structure, and therefore comparatively difficulty of roller is installed, and for improving installation efficiency, mostly adopts the nylon cages of split type structure at present, is to be provided with radial opening as split surface at the lintel middle part, a pocket hole of nylon cages.Because retainer is that nonmetallic material are made, utilize the resiliently deformable of retainer itself, very convenient when roller is installed, solved the low problem of bearing installation efficiency.But the retainer of this structure is when bearing working, because the split surface of retainer does not form connection, because existing the gap between the retainer split surface, makes retainer distortion and formation ellipse can occur.This again so that on the retainer central position in each roller pocket hole change, increase with the oscillation space of the axle that matches, under the effect of gravity and centrifugal force, after roller is subject to impact force, the variation meeting of the movement locus of roller impacts transmission shaft or driving gear, cause retainer to scatter on the one hand, thrust-bearing was lost efficacy; On the other hand, also increase the resistance to motion of thrust-bearing, namely increased the frictional force of roller, caused heating and the working life of shortening thrust-bearing.
For addressing the above problem, some present bearings are provided with groove vertically at end face of opening of retainer, the other end of retainer opening is provided with projection vertically, projection on one end face of retainer is connected in the groove on the other end, makes the split surface of retainer form linkage structure.When the assembling roller; although retainer is opening-wide state; the installation roller is convenient and swift; but retainer is from radially carrying out subdivision, and the installation of its roller is ecto-entad, in order to guarantee the intensity of retainer; the width of fender bracket pocket hole beam can not be too little; therefore under certain installing space condition, the installation quantity of its roller can not increase, and therefore can't further improve the bearing capacity of bearing.
Summary of the invention
It is easy for installation that the purpose of this utility model provides, and can improve a kind of thrust-bearing nylon split retainer of bearing capacity.
The utility model is that the technological scheme that achieves the above object is: a kind of thrust-bearing nylon split retainer, it is characterized in that: comprise in the circumferential direction of the circle left stretcher body and the right stretcher body of subdivision, described left stretcher body comprises left outside circle and left inside circle, be evenly equipped with in the circumferential direction of the circle the left pocket hole beam more than ten between left inside circle and the left outside circle, the bi-side of left pocket hole beam tilt from the inside to the outside, and the left pocket hole beam more than at least five (is positioned at left outside circle mating face and is provided with plural left positioning hole and plural left locating column; Described right stretcher body comprises right outside circle and right inside circle, be provided with the right pocket hole beam ten or more corresponding with left pocket hole beam between right inside circle and the right outside circle, the bi-side of right pocket hole beam tilt from the inside to the outside, the right outside circle mating face of the right pocket hole beam more than at least five is provided with plural right positioning hole and plural right locating column, the left locating column close-fitting of on the left stretcher body each is installed in each self-corresponding right positioning hole of right stretcher body, the right locating column close-fitting of on the right stretcher body each is installed in each self-corresponding left positioning hole of left stretcher body, and the left inside circle mating face of left stretcher body is fixedly connected with the right inside circle mating face of right stretcher body.
Nylon split retainer of the present utility model is left stretcher body and the right stretcher body of in the circumferential direction of the circle subdivision, and each the left locating column close-fitting on the left stretcher body is installed on the right stretcher body in each self-corresponding right positioning hole, the right locating column close-fitting of on the right stretcher body each is installed in each self-corresponding each left positioning hole of left stretcher body, the left outside circle of left stretcher body is connected with the right outside circle of right stretcher body, and the left inside circle mating face of left stretcher body is fixedly connected with the right inside circle mating face of right stretcher body, therefore can satisfy the precision of retainer, roller rotates in the pocket hole and can not be moved, improved the stressing conditions that is installed in roller on the split retainer, the variation meeting that reduces its movement locus impacts transmission shaft or driving gear, and the resistance to motion of thrust-bearing, reduce the thrust-bearing kinetic friction force, the working life that can improve thrust-bearing.The utility model adopts the retainer structure of Split type structure, when the assembling roller, retainer is opening-wide state, because the both sides of pocket hole, left and right sides beam have the inclined-plane, roller from inside to outside can be installed, therefore the width of outer side pocket hole fore shaft width can further dwindle, not only easy for installation, and satisfy at unidimensional retainer under the prerequisite of desirable strength, the pocket hole number can be increased, ratio is often by a plurality of two rollers of structure, and the bearing capacity of raising bearing.
