Abstract
The utility model discloses a kind of High-Speed Cylindrical Roller Bearing Cage, comprise two ribs and window crossbeam, two ribs are along the circumferential direction fixed together by window crossbeam, on the upper-end surface of window crossbeam, broad ways is provided with fore shaft, the upper-end surface of window crossbeam also offers groove along its length, and groove is through fore shaft, and the rib of fenestra both sides is respectively arranged with boss.The utility model can improve greasy property and the limit speed of roller bearing, is applicable to High-Speed Cylindrical Roller Bearing.
Description
Technical field
The utility model relates to retainer technical field, particularly relates to a kind of High-Speed Cylindrical Roller Bearing Cage.
Background technique
As everyone knows, roller bearing wants to reach at a high speed, must reduce internal friction, and then reduces heat generation, reduces temperature rise.The friction of cylindrical roller inside comprises the friction of cylindrical roller end face and lasso rib, the friction between cylindrical roller and retainer and other frictions; And the friction between cylindrical roller and retainer is divided into cylindrical roller rolling surface and the friction between retainer fenestra and fore shaft and the friction between cylindrical roller end face and retainer fenestra rib face.
Traditional cylinder roller bearing retainer is designed to fenestra crossbeam internal diameter direction and external diameter direction all arranges fore shaft, and between such roller rolls surface and retainer crossbeam and fore shaft, friction area more greatly and more difficult formation lubricating film, and frictional heat produces thus.On the other hand, retainer fenestra rib face is designed to plane, all produces with retainer and rub within the scope of the whole end face diameter of such roller, produces heat larger.The temperature rise that these frictions cause all governs the High Rotation Speed of roller bearing.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of High-Speed Cylindrical Roller Bearing Cage.
In order to realize foregoing invention object, the utility model adopts technological scheme as described below:
A kind of High-Speed Cylindrical Roller Bearing Cage, comprise two ribs and window crossbeam, two ribs are along the circumferential direction fixed together by window crossbeam, on the upper-end surface of window crossbeam, broad ways is provided with fore shaft, the upper-end surface of window crossbeam also offers groove along its length, and groove is through fore shaft, and the rib of fenestra both sides is respectively arranged with boss.
Further, a side of described boss is concordant with the inner ring edge of rib, and another corresponding side is positioned at the center of rib side.
Owing to have employed technique scheme, the utility model has following superiority:
1, the upper-end surface only on fenestra crossbeam arranges fore shaft, lower end surface does not arrange fore shaft, increase inside configuration space, ensure that the oiling agent in roller and retainer fenestra gap is sufficient, be convenient to form lubricant film, improve greasy property, reduce the generation of frictional heat;
2, two corresponding boss are set on the side of fenestra both sides rib, make the contact of roller end face only center very zonule and rib side, and avoid the contact of the high roller end face edge of linear velocity and retainer rib side, reduce the area of contact of retainer rib and roller end face, improve greasy property, reduce the generation of frictional heat;
3, on window crossbeam, offer groove, increase inner space, and effectively can store lubricating grease, temperature rise can be reduced by efficiently radiates heat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-boss; 2-fore shaft; 3-groove; 4-rib; 5-window crossbeam.
Embodiment
As shown in Figure 1, a kind of High-Speed Cylindrical Roller Bearing Cage, comprise two ribs 4 and window crossbeam 5, two ribs 4 are along the circumferential direction fixed together by window crossbeam 5, on the upper-end surface of window crossbeam 5, broad ways is provided with fore shaft 2, the upper-end surface of window crossbeam 5 also offers groove 3 along its length, and groove 3 is through fore shaft 2, and the rib of fenestra both sides is respectively arranged with boss 1.
One side of described boss 1 is concordant with the inner ring edge of rib 4, and another corresponding side is positioned at the center of rib side, and the line of centres of two boss and the longitudinal center line of roller are located along the same line; When such design makes roller rotate, the surface of contact of end face and retainer reduces greatly, surface of contact is only very little centered by roller end face center of circle circle, and the edge of end face, the higher annular region of linear velocity then not with retainer rib contacts side surfaces, the design of boss greatly reduces area of contact, improves greasy property, reduces the generation of frictional heat.
Groove 3 is offered in the upper-end surface of window crossbeam, bearing retainer when running up is made to store lubricating grease, this retainer is applicable to outer pilot bearing, such design makes retainer external diameter and outer ring raceway more easily form lubricant film, and increase inner space, be conducive to heat radiation, reduce temperature rise, improve bearing limit speed.
On the beam of retainer window both sides, the fore shaft comprised on beam opens the groove 3 of several angle, bearing retainer when running up is made to store lubricating grease, this retainer is applicable to outer pilot bearing, such design makes retainer external diameter and outer ring raceway more easily form lubricant film, and increase inner space, be conducive to heat radiation, reduce temperature rise, improve bearing limit speed.
In sum, because special construction of the present utility model is arranged, improve greasy property and the limit speed of roller bearing, be applicable to High-Speed Cylindrical Roller Bearing.
