Description
Technical field
The present invention relates to a kind of bearing outer ring, especially a kind of high-speed precision bearing depot fat outer ring structure.
Background technique
At present, the lubricating system of high-speed bearing mainly is by oil lubrication, but when adopting oil mist lubrication, need to have the input of air compressor source of the gas simultaneously, also will consume a certain amount of lubricant oil every day, lubricant oil enter aerial after can be atomized with the source of the gas of air compressor in the course of the work simultaneously, when working long hours, gas concentration increases in the air of working environment, and is very big to the health of human body influence, 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, and also not wishing has mist of oil in the working environment, 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 the 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 objective of the invention is to overcome the deficiencies in the prior art, can better store lubricating grease and be supplied to rolling element to make the high-speed precision bearing depot fat outer ring structure of bearing life thereby provide a kind of.
According to technological scheme provided by the invention, described high-speed precision bearing depot fat outer ring structure, comprise outer ring body, interior round stage casing at outer ring body is provided with raceway, section is provided with section cylndrical surface, a left side on the interior circle left side of outer ring body, the right section of interior circle at outer ring body is provided with right section cylndrical surface, and section cylndrical surface, a left side links to each other by raceway with right section cylndrical surface, and the diameter of section cylndrical surface, a left side is less than the diameter of right section cylndrical surface; In the axial cross section of outer ring body, described raceway is one section circular arc; In raceway, circumferentially offer oil storage tank along it, be provided with first seal groove at the interior circle of the outer ring body in left side, left side section cylndrical surface, be provided with second seal groove at the interior circle of the outer ring body on right section right side, cylndrical surface.
Described oil storage tank is opened in the raceway of close right section position, cylndrical surface.
Circle radius is greater than circle radius in the outer ring body of section position, cylndrical surface, a left side in the outer ring body of the first seal groove notch position.Circle radius is greater than circle radius in the outer ring body of right section position, cylndrical surface in the outer ring body of the second seal groove notch position.In the axial cross section of outer ring body, the angle that the line in the mid point of raceway place circular arc and the center of circle of described raceway place circular arc becomes with the line in oil storage tank notch left part and the circular arc center of circle, described raceway place be 10 ~ 20 ° in the axial cross section of outer ring body, the line in the mid point of raceway place circular arc and the center of circle of described raceway place circular arc is 15 ° with the angle that the line in oil storage tank notch left part and the circular arc center of circle, described raceway place becomes.
After the present invention uses, when bearing can better store lubricating grease when rotating at a high speed, and the lubricating grease that stores constantly can be supplied to rolling element, thereby make the life-span raising about 20% of bearing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: this high-speed precision bearing depot fat outer ring structure, comprise outer ring body 1, interior round stage casing at outer ring body 1 is provided with raceway 1.1, section is provided with section cylndrical surface 1.2, a left side on the interior circle left side of outer ring body 1, the right section of interior circle at outer ring body 1 is provided with right section cylndrical surface 1.3, section cylndrical surface 1.2, a left side links to each other by raceway 1.1 with right section cylndrical surface 1.3, and the diameter of section cylndrical surface 1.2, a left side is less than the diameter of right section cylndrical surface 1.3; In the axial cross section of outer ring body 1, described raceway 1.1 is one section circular arc; In raceway 1.1, circumferentially offer oil storage tank 1.4 along it, be provided with first seal groove 1.5 at the interior circle of the outer ring body 1 in left side section 1.2 left sides, cylndrical surface, be provided with second seal groove 1.6 at the interior circle of the outer ring body 1 on right section 1.3 right sides, cylndrical surface.
Described oil storage tank 1.4 is opened in the raceway 1.1 of close right section 1.3 positions, cylndrical surface.
