Abstract
The utility model discloses a self-lubricating bearing with a conduit penetrating the top end surface aiming to provide a bearing with backflow guiding effect, improved lubricating effect and increased durability. The utility model comprises a shaft aperture for the pivoting and rotating of a rotation shaft, peripheral surface, top end surface and bottom end surface, wherein at least one conduit which is extended to the top end surface is arranged on the wall surface of the shaft aperture, thereby the conduit penetrating the top end surface is formed, further the other end of the conduit is extended near the bottom end surface.
Description
Technical field
The utility model belongs to bearing, particularly a kind of self-lubricating bearing with perforation top end conduit.
Background technique
Self-lubricating bearing of commonly using or oil-impregnated bearing all are to keep lubricated and the reduction frictional loss by lubricating oil.Therefore, how to prevent that self-lubricating bearing or oil-impregnated bearing lubricant oil run off, become and keep the major subjects of lubricating and improving its frictional loss.In order to prevent that the lubricant oil in the bearing runs off, generally pad is set at the bearing two ends, flow out to stop bearing internal lubrication oil.Yet, the outflow that pad only can delay internal lubrication oil is set at the bearing two ends, but can't stop internal lubrication oil to flow out effectively fully, so, be necessary further to utilize additive method to prevent the loss of lubricant oil in the self-lubricating bearing.
As shown in Figure 4, the fan of self-lubricating bearing 905 is commonly used in disclosed a kind of use, and it comprises pedestal group 902 and is incorporated into flabellum group 901 on the pedestal group 902.Group is established self-lubricating bearing 905 on the pedestal group 902, and is provided with long-pending oil groove 906 in self-lubricating bearing 905 belows.Flabellum group 901 running shafts 903 are mounted in the self-lubricating bearing 905, and its surface ring is established spiral lamination 904.During running shaft 903 rotation, the lubricant oil between running shaft 903 and the self-lubricating bearing 905 is collected via the spiral lamination 904 on running shaft 903 surfaces and is directed to long-pending oil groove 906, to reduce the loss of lubricant oil, the working life of prolongation self-lubricating bearing 905.
Above-mentioned conventional construction, though can reach the effect that lubricant oil is directed to long-pending oil groove 906 by the spiral lamination 904 that is located on running shaft 903 surfaces, but the shaft hole inner wall of self-lubricating bearing 905 there is no lubricant oil backflow guide path, therefore lubricant oil still can be by running shaft 903 and 905 losses of self-lubricating bearing, thereby can't reach the purpose of lubricating rotating shaft.
Summary of the invention
The purpose of this utility model provides a kind of self-lubricating bearing that connects the top end conduit that has with reflux guiding effect, raising lubrication effect and working life.
The utlity model has the axis hole, outer circumferential face, top end and the bottom end that articulate rotation for rotating shaft; Be provided with the conduit that extends to top end at least together in the axis hole wall, to form the conduit that connects top end, the other end of conduit extends near the bottom end.
Wherein:
Conduit is a shape in the shape of a spiral.
Perforation end and top end that conduit extends to top end are vertical configuration.
Perforation end and top end that conduit extends to top end are the oblique angle.
Owing to the utlity model has the axis hole, outer circumferential face, top end and the bottom end that articulate rotation for rotating shaft; Be provided with the conduit that extends to top end at least together in the axis hole wall, to form the conduit that connects top end, the other end of conduit extends near the bottom end.During use, rotating shaft is articulated in the axis hole, when rotating shaft is rotated in axis hole, contained lubricant oil can upwards be climbed sharply between rotating shaft and axis hole wall by the rotation of rotating shaft in the axis hole, and the lubricant oil of climbing sharply can enter in the conduit when running into the conduit that connects top end, and follow the bottom that conduit is back to conduit, form lubricant oil in the conduit bottom and build up; When lubricant oil accumulates in the conduit bottom when a certain amount of, the rotating shaft that promptly is rotated dial from, thereby climb sharply along the axis hole wall once again; So, the lubricant oil in the utility model is recycled between rotating shaft and shaft hole inner wall, make that lubricant oil can not run off in it, and can keep permanent from moistening function, and then improve the utility model working life.Not only have the guiding of backflow effect, improve lubrication effect, and improve working life, thereby reach the purpose of this utility model.

Embodiment
As shown in Figure 1, the utlity model has the self-lubricating bearing 1 of guiding conduit that refluxes and have axis hole 11, outer circumferential face 10, top end 13 and the bottom end 14 that articulates rotation for rotating shaft 2.Be provided with several in axis hole 11 walls and extend to top end 13 to form the conduit 12 that connects top end 13, conduit 12 is preferably shape conduit in the shape of a spiral, and its perforation end and top end 13 that extends to top end 13 is vertical configuration, and the best also can be the oblique angle; The other end of conduit 12 extends near the bottom end 14.
As shown in Figure 2, rotating shaft 2 is articulated in the utility model axis hole 11.When rotating shaft 2 is rotated in axis hole 11, contained lubricant oil can upwards be climbed sharply between rotating shaft 2 and axis hole 11 walls by the rotation of rotating shaft 2 in the axis hole 11, and the lubricant oil of climbing sharply can enter in the conduit 12 when running into the conduit 12 that connects top end 13, and lubricant oil can follow the bottom that conduit 12 is back to conduit 12, forms lubricant oil in conduit 12 bottoms and builds up; When lubricant oil accumulates in conduit 12 bottoms when a certain amount of, 2 groups of rotating shafts that promptly is rotated from, thereby climb sharply along axis hole 11 walls once again.So, the lubricant oil in the utility model is recycled between rotating shaft 2 and axis hole 11 inwalls, make that lubricant oil can not run off in it, and then raising the utility model working life.
Connect conduit 12 by being arranged at the utility model axis hole 11 inwalls, when rotating shaft 2 is rotated in the utility model, make lubricant oil in the utility model by conduit 12 circulating refluxs to top end 13; Again and since conduit 12 the other ends extend near the bottom end 14, and non-through bottom end 14, therefore, lubricated congesting of oil place is formed on conduit 12 bottoms, and the lubricant oil of building up also can be by the rotation of rotating shaft 2 by band from, after axis hole 11 inwalls are upwards climbed sharply, enter conduit 12 reflux cycle more again.Therefore, the lubricant oil in the utility model can not run off, and can keep moistening function for a long time certainly, and then can improve its working life.
