Greatly；Roller end face is run on a bank right angle flange resistance serious wear, and easily thrust rib is racked；Retainer takes the % of rolling element 15
One 30 % bearing position, roller stress supporting-point are restricted；Reversing of bringing to a halt again should not be returned, roller easily breaks guarantor
Holder pocket hole；Simple grain roller axial string momentum is larger, and run on a bank right angle flange of roller is detained and can not overcome.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of Jing Yin cylinder roller bearing, can effectively reduce noise, carry
Lifting shaft holds service behaviour.
Realize the present utility model purpose technical scheme：
A kind of Jing Yin cylinder roller bearing, including inside race and outer collar, inside race are located at the inner side of outer collar, its feature
It is：Several rollers are provided between inside race and outer collar, roller is uniformly arranged along retainer circumferencial direction, and roller is in cylinder
Shape, the centre position of roller are provided with toroidal cavity；Retainer is provided between inside race and outer collar, overall is in annular, is protected
Hold frame circumference and be provided with tooth mouth, toroidal cavity and the retainer tooth mouth relative engagement of roller, roller is limited by the tooth mouth of retainer
System bounce and displacement are moved.
Further, in cone, inside race, outer collar axial direction both ends are equipped with rib, rib inner side at the both ends of roller
In inclined-plane, the circular cone inclined-plane relative engagement on the inclined-plane and roller both ends.
Further, inside race is made up of left inside lasso and right inside race, and left and right faces vertically for left lasso and right lasso
Face is set.
Further, retainer is located on the inside of outer collar, and roller is arranged between retainer and inside race；Or roller is set
It is placed between retainer and outer collar.
Further, two end surfaces of roller are cheated provided with circular depressed.
Further, the axial end of outer collar is provided with dust cap biserial mounting groove.
Further, it is in C word shapes that retainer entirety annulus, which is provided with opening at one,.
Further, the tooth mouth of retainer is straight-tooth, helical teeth or bucket tooth shape.
Further, retainer is Elastic Steel retainer, plastic cage or steel bar shape retainer, Elastic Steel retainer
Tooth mouth length is shorter than the diameter of roller groove by 1/5th；The tooth mouth length of plastic cage will be with the diameter dimension of roller groove
It is identical；The tooth mouth length of steel bar shape retainer is longer than the diameter of roller groove by 1/5th.
The utility model has the advantage that：
The utility model roller cylindrical form, retainer, the centre position of roller are provided between inside race and outer collar
Provided with circular groove, roller is moved by the tooth mouth agretope of retainer.Retainer can effectively limit the bounce of roller, prevent
Beat, isolation roller contact friction with roller face, reducing friction resistance, improve safety coefficient, and retainer axial space is more
Greatly, heat-sinking capability is stronger.The utility model is effectively reduced caused by roller bounce by cylindrical roller and retainer structure
Noise, it is possible to increase the running accuracy 50% of cylinder roller bearing, 2 percentage points of safety coefficient can be improved, can be reached
99.9%, the servo life-span can extend 30%.
The both ends of the utility model cylindrical roller can effectively improve the thrust capacity of roller, improve bearing in cone
Service behaviour；The utility model inside race, outer collar axial direction both ends are equipped with rib, be in inclined-plane on the inside of rib, the inclined-plane and
The conical inclined surface relative engagement at roller both ends.The utility model is relative with roller cone shape inclined-plane due to lasso rib inclined-plane
Coordinate, and make roller that there is more preferably running accuracy, so as to be effectively reduced roller end face and flange wear problem, while
Avoid the end face of roller from blocking to scratch with inclined-plane.
The utility model inside race is made up of face-to-face left inside lasso and right inside race, is more convenient maintenance.The utility model
Two end surfaces of roller are cheated provided with circular depressed, are the marks of hanging piece positioning and reference plane, are more convenient to safeguard.This practicality is new
The axial end of type outer collar is provided with dust cap biserial mounting groove, is more convenient sealing and uses.
The utility model retainer is Elastic Steel retainer, plastic cage or steel bar shape retainer, Elastic Steel retainer
Tooth mouth length it is smaller than the diameter of roller groove by 1/5th, the tooth mouth length of plastic cage will be with the diameter chi of roller groove
It is very little identical；The tooth mouth length of steel bar shape retainer is longer than the diameter of cylindrical roller groove by 1/5th.The utility model retainer
Cost is low, and intensity is high, is not easy to be pulled off.
