Description

Technical Field

[0001] The utility model relates to an improved invention in the technical field of bearing bushes, in particular to an improved invention of a thrust bush. Background Art

[0002] Existing thrust bearings are mostly made of integral alloy and machined after casting, which requires customized blades for metal cutting. Since the bearing body of the thrust bearing is connected to the thrust plate at a right angle, this structure limits the smooth transition of the tool path, easily generates burrs, and affects the service life of the tool. In addition, the tool needs to be customized, which increases the cost. 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 thrust washer that is easy to process and shape.

[0004] In order to solve the above technical problems, the utility model is implemented by adopting the following technical scheme: the thrust bearing comprises a bearing body and a thrust plate, and is characterized in that: the bearing body is semicircular, the two thrust plates are integrally formed at the axial ends of the bearing body, an annular guide groove is provided in the middle of the inner circle of the bearing body, a radial through hole is opened on the annular guide groove, a positioning groove is provided on the outer end face of the thrust plate, and a cutting-formed R angle transition is adopted at the connection between the bearing body and the thrust plate.

[0005] The outer circle of the bearing bush body is provided with grooves which are arranged on both axial sides of the annular guide groove, and the two groove walls of the groove are arranged to be inclined outwards.

[0006] There are two positioning grooves, which are symmetrically distributed on the outer end surface of the thrust plate.

[0007] There are two radial through holes, which are symmetrically distributed on the annular guide groove.

[0008] The beneficial effect of the utility model is that the improved thrust bearing adopts R angle transition at the connection between the bearing body and the thrust plate, and the two groove walls of the groove are inclined outward, which is convenient for improving the tool path, can reduce the generation of burrs in the cutting and forming process and increase the life of the cutting tool. 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. DETAILED DESCRIPTION

[0011] 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 1The thrust pad includes a bearing body 1 and a thrust plate 2. The bearing body 1 is semicircular, and the two thrust plates 2 are integrally formed at the two axial ends of the bearing body 1. An annular guide groove 3 is provided in the middle of the inner circle of the bearing body 1, and a radial through hole 4 is opened on the annular guide groove 3. The annular guide groove 3 and the radial through hole 4 cooperate with each other to form the oil guide structure of the thrust pad. A positioning groove 5 is provided on the outer end surface of the thrust plate 2. The connection between the bearing body 1 and the thrust plate 2 adopts a cutting-formed R angle 6 transition; the outer circle of the bearing body 1 is provided with a groove 7 arranged on both axial sides of the annular guide groove 3, and the two groove walls 8 of the groove 7 are inclined outward. The R angle 6 and the outwardly inclined groove wall 8 are convenient for improving the tool path, which can minimize the generation of burrs during the cutting process and increase the life of the cutting tool.

[0012] As a further improved specific implementation, two positioning grooves 5 are provided, which are symmetrically distributed on the outer end surface of the thrust plate 2 to ensure positioning stability.

[0013] As a further improved specific implementation, two radial through holes 4 are provided, which are symmetrically distributed on the annular guide groove 3 to ensure the oil guiding efficiency.

[0014] 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.
