Abstract
The invention discloses a rolling bearing retainer with micro pits. The micro pits capable of storing lubricating oil or lubricating grease are formed on the contact surface of the rolling bearing retainer with a rolling body; the micro pits have a circular shape; the ratio of the total area of the circular micro pits to the area of the rolling body contact surface is 10 to 20 percent; the ratio of the depth to the diameter of the micro pits is 0.05 to 0.2; and various micro pits are uniformly arranged on the rolling body contact surface. The rolling bearing retainer with the micro pits can store the lubricating oil or lubricating grease, provides abundant lubricants for a rolling bearing and improves the lubricating property of the rolling bearing; moreover, the retainer contains a lubricant to contribute to lubrication and protection per se, and the service life of a bearing is comprehensively prolonged.
Description
Technical field
The present invention relates to rolling bearing retainer, especially relate to a kind of rolling bearing retainer with little hole.
Background technique
The all or part of parcel rolling element of rolling bearing retainer, its effect is that rolling element is separated equably, and the guiding rolling element remains on the raceway and moves.All kinds of rolling bearings all are evenly to separate rolling element and guide rolling element to move on raceway as the retainer of rolling bearings such as deep groove ball bearing, roller bearing, tapered roller bearing, to the greasy property of bearing without any help.In addition, when rolling bearing was worked, the high temperature, violent friction, the wearing and tearing that cause owing to friction may make retainer burn or fracture, therefore lubricated also very important to retainer.Especially in tapered roller bearing, bearing will bear combined load (radial and axial), wants bearing load between tapered roller end face and the retainer, herein work under bad environment, enough lubricant oil is arranged, and retainer is if can kind of lubricant storage will greatly improve the greasy property of bearing herein.
Based on above-mentioned background, if retainer can kind of lubricant storage, the bearing when storing lubricating grease and offering work, the greasy property to bearing has huge help undoubtedly, improves its greasy property.Simultaneously, under the environment of high temperature, violent friction, self contains oiling agent retainer, helps the lubricated of himself, prevents the bearing lubrication inefficacy.
Summary of the invention
The object of the present invention is to provide a kind of rolling bearing retainer with little hole, rolling bearing retainer that can kind of lubricant storage increases the function of retainer kind of lubricant storage, will obtain better bearing working greasy property, raising bearing working life.
The technical solution used in the present invention is:
Rolling bearing retainer of the present invention and rolling element contact surface are provided with little hole that can store lubricant oil or lubricating grease.
Described little hole be shaped as circle, circular little hole gross area is 10% ~ 20% with rolling element contact surface area ratio, little hole aspect ratio is 0.05 ~ 0.2, each little hole is evenly arranged in the rolling element contact surface.
Described rolling bearing retainer is the tapered roller bearing retainer, and tapered roller bearing retainer and circular cone rolling element contact surface are provided with little hole that can store lubricant oil or lubricating grease.
Described rolling bearing retainer is a cylinder roller bearing retainer, and cylinder roller bearing retainer and cylinder rolling element contact surface are provided with little hole that can store lubricant oil or lubricating grease.
Described rolling bearing retainer is a ball bearing retainer, and ball bearing retainer and ball rolling element contact surface are provided with little hole that can store lubricant oil or lubricating grease.
The beneficial effect that the present invention has is:
1, the little hole of rolling bearing retainer energy kind of lubricant storage during rolling bearing work, is taken oiling agent out of when rolling element rolls, and the oiling agent of bearing abundance is provided, and improves the greasy property of bearing;
2, oiling agent is contained in the little hole of rolling bearing retainer, can sufficient lubrication retainer, prevent that retainer from burning, rupturing under bad working environment;
3, grease up in the little hole of rolling bearing retainer is very suitable for disposable lifelong lubricated bearing, can be this class bearing sufficient oiling agent is provided;
4, in tapered roller bearing, bearing will bear radial and axial power, and under Action of Combined Loads, tapered roller one end face and retainer will push, and operating conditions is abominable herein, and retainer is provided with little hole kind of lubricant storage herein, improves its greasy property.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Rolling bearing retainer and rolling element contact surface are provided with little hole that can store lubricant oil or lubricating grease.
As shown in Figure 1, described rolling bearing retainer is a tapered roller bearing retainer 1, and the conical surface 3 that the small end face 2 that the tapered roller bearing retainer contacts with tapered roller, retainer contact with tapered roller is equipped with little hole that can store lubricant oil or lubricating grease with the surface of the large end face 4 that retainer contacts with tapered roller.
As shown in Figure 2, described rolling bearing retainer is a cylinder roller bearing retainer 5, and the cylndrical surface 6 that retainer contacts with cylindrical roller is provided with little hole that can store lubricant oil or lubricating grease.
As shown in Figure 3, described rolling bearing retainer is a ball bearing retainer 7, and the sphere 8 that retainer contacts with spin is provided with little hole that can store lubricant oil or lubricating grease.
As shown in Figure 4, be the enlarged view that each surface micro-pit is arranged, described little hole be a circle, as the center line line and the Y orientation angle of scheming each little hole be 20 ° ± 5 °, and arrangement mode forms by Fig. 4 mapping mode.The area ratio in little hole also claims area density, is 10% ~ 20%, and the area ratio is meant the ratio of circular little hole gross area and rolling element contact surface area; As shown in Figure 4, little hole aspect ratio is 0.05 ~ 0.2, and aspect ratio refers among Fig. 5
H/dValue,
hBe little hole degree of depth,
dBe little hole diameter,
dSpan be 100 microns to 200 microns.Each little hole is evenly arranged in the rolling element contact surface, among Fig. 4 on 20 ° ± 5 ° oblique lines the distance of adjacent round pool by area than and
dValue is determined.
At last, need to replenish be the load of rolling bearing mainly by the rolling element carrying, therefore on retainer, be provided with the bearer properties that little hole can not influence rolling bearing.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
