Abstract
The utility model relates to a cylindrical roller bearing and a solid retainer thereof. The cylindrical roller bearing comprises a solid retainer and a retainer end cover arranged at the end part of the solid retainer, wherein an oil-accommodating structure is arranged on the outer circumference of the solid retainer. The oil-accommodating structure is formed by the oil-accommodating concave face on the outer circumference of the solid retainer. The oil-accommodating concave face is located in the position of the meshed cross beam of the outer circumference of the solid retainer. The oil-accommodating concave face falls below the outer circumference of the root part of the solid retainer. A ridge is formed at the root end of the solid retainer. The ridge, the oil-accommodating concave face and the outer margin of the retainer end cover combine to form an oil-accommodating groove. With the structure, the space for accommodating lubricating grease between the bearing solid retainer and the outer ring raceway is increased, so that the storage volume of the lubricating grease is increased, the lubrication maintenance cycle during the operation process is prolonged relatively, and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of roller bearing and solid cage thereof.
Background technique
The structure of straight roller bearing as shown in Figure 1, this bearing comprises inner ring 2 and outer ring 1, assembly for constituting between inner ring 2 and the outer ring 1 by solid cage 5, retainer end cap 6 and cylindrical roller 4, solid cage 5 and retainer end cap 6 make up by the seam of being located at its opposing end surface and are riveted together by rivet 3, and cylindrical roller 4 is arranged in the cylindrical pocket hole 8 of solid cage 5; Between cylindrical roller 4 and solid cage 5 and retainer end cap 6, exist very little gap, this gap has guaranteed that cylindrical roller 4 surfaces can be covered with lubricant film under working condition, thereby keep cylindrical roller 4 to rotate between inside and outside circle raceway flexibly, the pocket hole lintel 7 of solid cage has played the effect of isolating adjacent column roller 4.This roller bearing is at main bearing radial force of when work, and cylindrical roller 4 rotation of rolling on the circular raceway of outer ring 1 and inner ring 2 is filled with lubricant grease and lubricates guaranteeing on circular raceway.
The deficiency of above-mentioned roller bearing is that the outer ring surface of bearing holder is smooth cylndrical surface, do not store the oil-bearing structure of lubricant grease on it, the oil storage space that makes retainer and outer ring raceway form is less, cause the lubricant grease amount that to fill in the bearing less, it is shorter so once to fill the lubrication interval that can keep after the lubricant grease, bearing is at work in case the lubricant oil disappearance occurs, will produce cylindrical roller 4 with in, dry friction between outer ring raceway, produce burn, cause damage of bearings, and then influence the bearing proper functioning, so for the working life that ensures bearing and greasy property in use, just require the user regularly to be lubricated maintenance with the supplemental lubrication grease, thereby increased user's maintenance cost bearing.
The model utility content
The purpose of this utility model provides a kind of reserves that can increase lubricant grease in the bearing, prolongs the roller bearing in its lubricated maintenance cycle.In addition, the utility model also provides the solid cage of this roller bearing.
For achieving the above object, the utility model adopts following technological scheme: a kind of roller bearing, comprise solid cage and the retainer end cap that is loaded on the solid cage end, and the outer ring surface of solid cage is provided with oil-bearing structure.
Described oil-bearing structure is formed by the oil storage concave surface of being located on the solid cage outer ring surface.
Described oil storage concave surface is positioned at the lintel position, pocket hole of solid cage outer ring surface, this oil storage concave surface is lower than the outer ring surface of solid cage foundation part, form flange at retainer foundation end, the outer rim of this flange and described oil storage concave surface and retainer end cap constitutes oil storage grooves.
The technological scheme of the solid cage of the roller bearing that the utility model provides is as follows: a kind of solid cage of roller bearing, the outer ring surface of this solid cage is provided with oil-bearing structure.
Described oil-bearing structure is formed by the oil storage concave surface of being located on the solid cage outer ring surface.
Described oil storage concave surface is positioned at the lintel position, pocket hole of solid cage outer ring surface, and this oil storage concave surface is lower than the outer ring surface of solid cage foundation part, forms flange at retainer foundation end.
After the utility model adopts said structure, increase the space that stores lubricant grease between bearing holder and outer ring raceway, thereby can increase the storage volume of lubricant grease, relatively prolonged the lubricated maintenance cycle in the using process, reduced maintenance cost.The utility model can guarantee its greasy property more fully when satisfying user's usage requirement, reduced bearing the user side because of short duration oil starvation and the accidents caused frequency, ensured the working life of bearing effectively; In addition, oil-bearing structure is formed by the oil storage concave surface on the retainer outer ring surface, and this oil storage concave surface is lower than retainer foundation end outer ring surface by the outer ring surface of pocket hole lintel part and forms, and makes simple and conveniently, is easy to realization.

Embodiment
The solid cage of roller bearing of the present utility model such as Fig. 4, shown in Figure 5, this solid cage is at Fig. 2, the improvement of carrying out on the basis of solid cage shown in Figure 3, after the improvement, pocket hole lintel outer ring surface 9 is lower than retainer foundation end outer ring surface 10 on the solid cage, like this, just formed flange at retainer foundation end, make and form the oil storage concave surface on the solid cage outer ring surface, this oil storage concave surface is oil-bearing structure, in solid cage and bearing, after the outer ring is assembled together, the flange of retainer foundation end cooperates with the outer ring, because the outer ring surface of pocket hole lintel part is made as the oil storage concave surface, strengthen the space that stores lubricant grease between retainer and outer ring raceway, thereby can increase the storage volume of lubricant grease in the bearing.Among Fig. 4,5, the 7th, pocket hole lintel, the 8th, cylindrical pocket hole.
Roller bearing of the present utility model as shown in Figure 6, this bearing is the improvement of carrying out on the basis of bearing shown in Figure 1, improvements are, solid cage 5 adopts the structure of Fig. 4, retainer shown in Figure 5, pocket hole lintel outer ring surface 9 is lower than retainer foundation end outer ring surface 10 on this solid cage, formed flange at retainer foundation end, make and form the oil storage concave surface on the solid cage outer ring surface, this oil storage concave surface is oil-bearing structure, has constituted oil storage grooves 11 jointly by the outer rim of retainer foundation end boss and described oil storage concave surface and retainer end cap.This bearing is compared with bearing shown in Figure 1, has increased the space that stores lubricant grease between retainer and outer ring raceway, thereby can increase the storage volume of lubricant grease, has relatively prolonged the lubricated maintenance cycle, reduces maintenance cost.
