Problems solved by technology

[0002] In the processing of tapered roller bearing inner ring and outer jacket oil groove, the traditional method usually uses welding tools, and manually grinds the tools through the comparison method to achieve the unity of tool and product design requirements. The width tolerance between them is small. If it is too wide, it will affect the overall structural strength of the part. If it is too narrow, the number of times the tool can be reused is limited. Moreover, it cannot achieve the effects of oil storage, dust storage, and raceway grinding overrun. often lose sight of the other

Embodiment 1

[0042] The processing technology of the inner ring and the outer casing oil groove of the tapered roller bearing includes the outer casing oil groove processing procedure and the inner ring oil groove processing procedure. The outer casing oil groove processing and the inner ring oil groove processing both include the processing of oil grooves of different shapes. The specific steps are as follows:

[0043] a. The oil groove processing of different jackets is divided into the oil groove processing under the condition of not grinding the blade and the oil groove processing under the condition of grinding the blade;

[0044] (1) The width of the oil groove processed without grinding the blade is not limited, specifically, it can be processed at any angle within 90° in the L direction, and the angle in the R direction is not less than 35°;

[0045] (2) The narrowest 0.8 mm 90° oil groove is processed by grinding blade;

[0046] b. Processing of different inner ring oil grooves: m...

Abstract

The invention relates to a tapered roller bearing inner ring and outer sleeve oil groove machining process, is suitable for machining oil grooves with different shapes of tapered roller bearing innerrings and outer sleeves, and belongs to the technical field of lathe work process machining. The tapered roller bearing inner ring and outer sleeve oil groove machining process comprises an outer sleeve oil groove machining procedure and an inner ring oil groove machining procedure, wherein the outer sleeve oil groove machining procedure and the inner ring oil groove machining procedure comprise machining of oil grooves with different shapes, the oil grooves with different shapes of the tapered roller bearing inner rings and the outer sleeves are machined by changing the shape of a blade, theshape of a cutter bar and the installation angle through grinding the blade, the problems that the center of an original cutter bar is high, the cutter bar is overhung too long to generate vibration lines, and the width and shape control and durability are poor in the cutter grinding process are solved by using a specific machine clamp cutter, and the requirements of convenient replacement, operation and adjustment, consistency and controllability mass production are met; and the machining requirements of the oil grooves with various shapes of the inner rings can be met by modifying the cutterbar and adjusting the cutter feeding angle of the cutter.
