Integrated thrust bearing shell

Abstract

The present invention relates to an integrated thrust bearing shell, which comprises a thrust bearing shell body, wherein one end of the thrust bearing shell body is provided with a positioning lip, both sides of the thrust bearing shell body extend outward in a direction perpendicular to the thrust bearing shell body and are provided with thrust sheets, steps are formed between the thrust sheet and thrust bearing shell body, the steps are provided with positioning holes, first notches are retained on both sides of the steps, an oil groove is arranged in the middle of the thrust bearing shell body and extends to both ends of the thrust bearing shell body along the axial direction of the thrust bearing shell body, the thrust bearing shell body is divided into two parts through the oil groove, an oil hole is arranged in the middle of the oil groove, an alloy layer is covered on the inner surface of the thrust bearing shell body, and an oxide protection film is covered on the outer surface of the thrust bearing shell body. According to the present invention, with the positioning lip and the positioning hole, the integrated thrust bearing shell can have the good fixation stability; and with the alloy layer and the oxide protection film, the integrated thrust bearing shell can have the corrosion resistance.

Description

technical field [0001] The invention relates to an integral thrust bearing bush. Background technique [0002] Integral thrust bearing bush is a common accessory for internal combustion engines such as diesel engines and gasoline engines and some transmission machinery, and is also a vulnerable part. With the development of automobiles, construction machinery, and agricultural machinery, the demand for internal combustion engines is increasing, especially for heavy vehicles. With the use and development, the technical requirements for the integral thrust bearing are getting higher and higher. [0003] At present, the common integral thrust bearings are mainly integral flanging type and edge riveting type. The integral flanging type integral thrust bearing has the advantages of good rigidity, convenient installation and high technical precision, but the production cost is the highest, and because of its rigidity, the distance between the two thrust plates is fixed, while the...

AI Technical Summary

Problems solved by technology

The cost of the final product of this production method is slightly lower than that of the integral flanged integral thrust bearing, but the process is more complicated, and the burrs generated by riveting and activation must undergo secondary treatment, otherwise the use effect will be affected

For some other detachable thrust-side bearings including this edging bearing, another defect is that the thrust plate cannot be separated from the bearing body after installation due to the riveting process, and the thrust plate appears during the production process. Some defects can lead to the scrapping of the entire bearing bush, increasing the risk and cost of loss
