AI Technical Summary
The lubrication method of traditional bearing shells has poor heat dissipation effect and cannot meet the needs of the actual working environment, resulting in direct friction between the bearing shells and the rotating shaft, increasing temperature, and easy burnout of the sliding bearings.
A high lubricating bearing shell is designed, including a semicircular bearing shell body, equipped with positioning lips, garbage trough and short oil trough. The length of the garbage trough occupies more than two-thirds of the axial length of the bearing shell, and the short oil trough is connected to the garbage trough to form a more sufficient lubrication and pressure relief effect.
By setting up interconnected garbage troughs and short oil troughs, more sufficient lubrication and pressure relief are achieved, and the particles generated by friction are cleaned up in time, extending the service life of the bearing shells.

Abstract
Description
Technical Field
[0001] The utility model relates to an improved invention of a bearing bush, in particular to an improved invention of a high-lubrication bearing bush. Background Art
[0002] The bearing is the part where the sliding bearing contacts the shaft. Therefore, when the sliding bearing is working, if the lubrication is poor or the heat dissipation is poor, there will be direct friction between the bearing and the shaft, causing the temperature to rise continuously, and eventually the sliding bearing will be burned out. At the same time, the bearing may also be damaged due to factors such as excessive load, high temperature, impurities in the lubricating oil, and abnormal viscosity. The traditional bearing lubrication method uses a combination of oil grooves and oil holes, which has poor heat dissipation effect and cannot meet the needs of the actual working environment. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a bearing bush with high lubrication and long service life.
[0004] In order to solve the above technical problems, the utility model is implemented by adopting the following technical scheme: this kind of high-lubrication bearing includes a bearing body, which is characterized in that: the bearing body is semicircular, the outer edge of the first pair of ports of the bearing body is provided with a positioning lip, the inner edge of the second pair of ports of the bearing body is provided with a garbage chute, the length direction of the garbage chute is axially arranged, the width direction of the garbage chute connects the second pair of ports with the inner side of the bearing body, a short oil groove is provided in the middle part of the inner circle of the bearing body, the short oil groove passes through the second pair of ports, and the short oil groove is connected to the garbage chute.
[0005] The cross section of the garbage chute in the width direction is a triangle.
[0006] The length of the garbage chute occupies more than two-thirds of the axial length of the bearing body.
[0007] The positioning lip is punched out vertically downward from the top of the first pair of openings of the bearing shell body.
[0008] The beneficial effect of the utility model is that the improved high-lubrication bearing shell can more fully lubricate the bearing shell joint by arranging the garbage trough and the short oil trough which are interconnected, and can better relieve pressure, so that the particles generated by friction can be cleaned away more timely and the service life can be increased. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0010] Figure 1 It is a structural schematic diagram of the utility model.
[0011] Figure 2 It is a structural side view of the utility model. DETAILED DESCRIPTION
[0012] The accompanying drawings show the structure of the utility model, and the following further describes its relevant details in conjunction with the accompanying drawings. Figure 1-2 The high-lubrication bearing includes a bearing body 1, which is semicircular. A positioning lip 3 is provided on the outer edge of the first pair of openings 2 of the bearing body 1, and a garbage chute 5 is provided on the inner edge of the second pair of openings 4 of the bearing body 1. The length direction of the garbage chute 5 is axially arranged, and the width direction of the garbage chute 5 connects the second pair of openings 4 and the inner side of the bearing body 1. A short oil groove 6 is provided in the middle of the inner circle of the bearing body 1. The short oil groove 6 runs through the second pair of openings 4, and the short oil groove 6 is connected to the garbage chute 5, completing radial and axial conduction, more fully lubricating the bearing connection, better pressure relief, and can more timely clean up the particles generated by friction, thereby increasing the service life.
[0013] As a further improved specific implementation, the cross-section of the garbage chute 5 in the width direction is triangular, which is convenient for cutting and forming, that is, cutting off the edges.
[0014] As a further improved specific implementation method, the length of the garbage chute 5 occupies more than two-thirds of the axial length of the bearing body 1, ensuring that the garbage chute 5 can lubricate, relieve pressure and clean particles.
[0015] As a further improved specific implementation method, the positioning lip 3 is punched out vertically downward from the top of the first pair of openings 2 of the bearing body 1. Specifically, the bearing material can be positioned, the positioning lip punch is started, and the positioning lip punch is used to punch out the positioning lip 3 vertically downward from the top of the bearing pair. This positioning lip 3 structure can prevent burrs from being generated around the positioning lip 3 and reduce bearing oil unloading.
[0016] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
