Abstract
The invention relates to an oil floating type bearing for an automobile. The oil floating type bearing for the automobile comprises a main rotary shaft. An annular shaft sleeve is arranged on the main rotary shaft; cover rings are arranged on two axial ends of the shaft sleeve; a closed shell is sleeved on the shaft sleeve, and comprises a bottom shell and a cover body; two ends of the bottom shell are opened; an annular baffle plate A is arranged on the opening at one end of the bottom shell; the cover body comprises an annular baffle plate B arranged at the other end of the bottom shell; the cover rings are arranged between the baffle plate A and the baffle plate B; an annular expansion ring A is arranged at a position, corresponding to an inner wall of the shaft sleeve, between the baffle plate A and the baffle plate B; an annular expansion ring B is arranged on an inner wall of the closed shell; lubricating grease is filled between the expansion ring A and the expansion ring B; a plurality of oil filler holes are processed in the inner wall of the shaft sleeve, and penetrates through the expansion ring A so as to communicate with a lubricating grease cavity formed by the expansion ring A and the expansion ring B; and a main oil filler hole is coaxially processed in the main rotary shaft.
Description
Technical field
The present invention relates to a kind of oil float formula automobile bearing, belong to field of bearings.
Background technology
Some noise requirements such as radiator fan are big, in the use field that motor driving force is small, the roller bearing of automobile fan spindle bearing is because its startup power is big, and the noise of high-speed rotation also compares and is difficult to ensure card, in addition the bearing that radiator fan is used is because longevity of service, dust is larger, and general roller bearing is it is difficult to ensure that such use duration and environment.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the technical problem of roller bearing durability difference high cost in the prior art, there is provided a kind of oil float formula automobile bearing.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of oil float formula automobile bearing,Including main shaft,An axle sleeve for annular is provided with the main shaft,A cover ring is each provided with the axial two ends of the axle sleeve,A closure is socketed with the axle sleeve,The closure includes drain pan and lid,Wherein drain pan both ends open,The shutter A of annular is provided with the one end open of drain pan,The lid includes being arranged on the annular shutter B of the drain pan other end,The cover ring is arranged between shutter A and shutter B,The expansion loop A of annular is provided between the inwall correspondence shutter A and shutter B of the axle sleeve,The expansion loop B of annular is provided with the inwall of the closure,Array is provided with some spacing garter spring B wherein on the inwall of expansion loop B,Array is provided with some spacing garter spring A on the outer wall of the expansion loop A,Lubricating grease is filled between the expansion loop A and expansion loop B,Some oil filler points are machined with the inwall of the axle sleeve,The oil filler point passes through expansion loop A and expansion loop,The grease pocket connection constituted between expansion loop B,Main oil filler point is coaxially machined with the main shaft,Connected by connecting hole between the main oil filler point and oil filler point.
Used as further innovation of the invention, the substrate that the cover ring is made including elastic metallic is provided with encapsulated layer in the cover ring.
Used as further innovation of the invention, the expansion loop A and expansion loop B is made of cellular PVC air bags.
Used as further innovation of the invention, the spacing garter spring A and spacing garter spring B are made of PTFE materials.
The beneficial effects of the invention are as follows：
The present invention forms a high pressure cavity by a composite seal mechanism, and the lubricating grease environment with certain pressure is produced by expansion loop, ensure that the good rotation of bearing, while the pressure by ensureing lubricating grease, ensure that the stability of bearing grease, spacing garter spring is prevented in some usage scenarios, and the air bag of PVC can be expanded and cause bearing stuck.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the invention.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, and basic structure of the invention is only illustrated in a schematic way, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1,The present invention is a kind of oil float formula automobile bearing,Including main shaft,An axle sleeve for annular 1 is provided with the main shaft,A cover ring 3 is each provided with the axial two ends of the axle sleeve 1,A closure is socketed with the axle sleeve 1,The closure includes drain pan 2 and lid,The wherein both ends open of drain pan 2,The shutter A of annular is provided with the one end open of drain pan 2,The lid includes being arranged on the annular shutter B of the other end of drain pan 2,The cover ring 3 is arranged between shutter A and shutter B,The expansion loop A5 of annular is provided between the inwall correspondence shutter A and shutter B of the axle sleeve 1,The expansion loop B4 of annular is provided with the inwall of the closure,The spacing garter spring A7 of some PTFE materials is provided with the outside wall surface of expansion loop A,Array is provided with some spacing garter spring B8 on the inwall of expansion loop B,Lubricating grease 6 is filled between the expansion loop A5 and expansion loop B4,Some oil filler points are machined with the inwall of the axle sleeve,The oil filler point 9 passes through expansion loop A and expansion loop,The grease pocket connection constituted between expansion loop B,Main oil filler point 11 is coaxially machined with the main shaft,Connected by connecting hole 10 between the main oil filler point 11 and oil filler point 9；
The substrate that the cover ring 3 is made including elastic metallic, is provided with encapsulated layer in the cover ring 3；
The expansion loop A5 and expansion loop B4 are made of cellular PVC air bags.
The present invention in a sealing structure for bilateral by increasing a cavity of lubricating grease 6, and 3 stroke of cover ring one by expansion loop and elasticity produces certain pressure to lubricating grease 6, lubricating grease 6 under certain pressure not only has good lubricating uniform degree, good support force can be provided simultaneously, form a kind of fluidised roller, with relatively low rotation friction, and relatively low noise.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff can carry out various changes and amendments without departing from the scope of the technological thought of the present invention' completely.The technical scope of this invention is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
