METHOD OF FIXING POLYMER TO METAL BEARING HOUSING Russian patent published in 1995 - IPC

Abstract RU 2047014 C1

FIELD: mechanical engineering. SUBSTANCE: rectangular profile is made on the side of housing 1 with a step over axes of grooves 2. Hard alloy tool 4 made up as a blunted cutter serves for bending each pair of walls 3 of one groove out. As a result, new grooves 5 are formed as dovetails. Housing 1, which is processed in so manner, is filled with a polymer from the side of the grooves. The bearing bushing of a given diameter is obtained after machining. EFFECT: enhanced reliability. 3 cl, 7 dwg
