Abstract

The utility model relates to a retaining frame of a high-speed precision bearing. Pockets are formed in a retaining frame body; grease storage grooves are formed in an outer circle of the retaining frame body along the circumferential direction and are corresponding to the pockets; the width of each grease storage groove is greater than the diameter of the corresponding pocket in the axis direction of the retaining frame body; the pockets are fillet rectangles; the diameter of each pocket in the axis direction of the retaining frame body is smaller than that of each pocket in the circumferential direction of the retaining frame body. After the retaining frame of the high-speed precision bearing is used, when a bearing rotates at a high speed, lubricating grease can be well stored, and the stored lubricating grease can be continuously supplied to a rolling body, so that the service life of the bearing is prolonged by about 30 percent.

Description

The retainer of high-speed precision bearing
Technical field
The utility model relates to a kind of bearing part, especially a kind of retainer of high-speed precision bearing.
Background technique
At present, the lubricating system of high-speed bearing is mainly by oil lubrication, but when adopting oil mist lubrication, need simultaneously to have the input of air compressor source of the gas, also will consume a certain amount of lubricant oil every day, simultaneously lubricant oil enters aerial after can together with the source of the gas of air compressor, being atomized in the course of the work, while working long hours, in the air of working environment, gas concentration increases, very large on the health of human body impact, and just do not bothered like this during grease lubrication, link described above can be saved.Therefore, a lot of applications are arranged, the user does not have the air compressor source of the gas, does not wish in working environment to have mist of oil yet, so they wish to adopt the bearing of grease lubrication.But also there are a lot of deficiencys in the bearing of grease lubrication at present.Evidence, the rotating speed of the rotating ratio grease lubrication of the bearing of oil lubrication improves 30%, and under same operating conditions, the bearing life of oil mist lubrication can improve 2 times than the bearing life of grease lubrication.Analyzing one of in-problem reason is the effect problem of oil lubrication.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of when bearing can better storing lubricating grease during at High Rotation Speed and be supplied to rolling element, can improve the retainer of the high-speed precision bearing in bearing working life.
The technological scheme provided according to the utility model, the retainer of described high-speed precision bearing, on the retainer body, offer the pocket hole, on the cylindrical of the retainer body of pocket hole site, offer oil storage tank along its circumferencial direction, the width of oil storage tank is greater than the diameter of pocket hole on retainer body axis direction; Described pocket hole is the fillet rectangular, and the pocket hole is positioned at diameter on retainer body axis direction and is less than the pocket hole and is positioned at the diameter on retainer body circumferencial direction.
In corresponding pocket hole, be positioned at the circumferencial direction along the retainer body on the trough floor of oil storage tank at two end part of the diameter on retainer body axis direction and offer oil guide slot.
After the utility model is used, when bearing can better storing lubricating grease during at High Rotation Speed, and the lubricating grease stored constantly can be supplied to rolling element, thereby make life-span raising 30% left and right of bearing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the retainer of this high-speed precision bearing, be included on retainer body 1 and offer pocket hole 1.1, on the cylindrical of the retainer body 1 of 1.1 positions, pocket hole, offer oil storage tank 1.2 along its circumferencial direction, for the effect of the storage grease that improved retainer, the width of oil storage tank 1.2 is greater than the diameter of pocket hole 1.1 on retainer body 1 axial direction; Described pocket hole 1.1 is the fillet rectangular, and pocket hole 1.1 is positioned at diameter on retainer body 1 axial direction and is less than pocket hole 1.1 and is positioned at the diameter on retainer body 1 circumferencial direction, be a<b, reduced like this axial internal clearance between retainer and rolling element, improved the dynamic balance performance of retainer.
In corresponding pocket hole 1.1, be positioned at the circumferencial direction along retainer body 1 on the trough floor of oil storage tank 1.2 at two end part of the diameter on retainer body 1 axial direction and offer oil guide slot 1.3, like this, increased the space that stores grease, during work, grease in outer ring raceway flows into the surface of rolling element by oil storage tank 1.2, oil guide slot 1.3 places, thereby improved the lubrication effect of bearing, improved the working life of bearing.
When making retainer of the present utility model, the cylindrical of retainer will increase, and the inner circle of retainer will be dwindled, and is conducive to increase the wall thickness of retainer.

Claims (2)
