Machining device and method for double-thrust sliding bearing in finish machining stage

Abstract

The invention discloses a machining device and method for a double-thrust sliding bearing in the finish machining stage. The device comprises two sets of pressing plate combinations; a bearing alloy end face F is placed on a base positioning working face to be reliably attached to the base positioning working face; after a bearing is aligned, the first set of pressing plate combination penetrates through an inner hole to tightly press a bearing alloy end face E for finish machining of an outer circle and the second set of pressing plate combination is used for pressing the side face of an outer circular ring groove from the outer portion of the bearing, so that finish machining of an inner hole and an alloy end face E is conducted; then the bearing is turned over, positioning and pressing are conducted through a positioning cylindrical pin and the second set of pressing plate combination, and finish machining of the alloy end face F is conducted. The clamping force layout is reasonable; automatic centering is achieved when the bearing is turned over, and alignment is not needed; the problem that the form and location tolerance cannot meet the design requirement due to the fact that an existing machining device clamps the outer circle of the bearing and the quality problem that a machined alloy end face is prone to being scratched are solved, and the form and location precision and the product quality of a double-thrust sliding bearing are guaranteed.

Description

Technical field [0001] The present invention relates to the field of sliding bearing processing, and Background technique [0002] Double push slip bearing is composed of bimetallic materials (carbon steel and tin-based alloys), the inner holes material and the two end surface materials are made of a tin based alloy. The bearing has two semi-cross-sectional structural features, mounted in the gear case box, used to support the gear shaft to transfer power, but can not only withstand the radial force, but also withstand the two-way axis The role of the force. [0003] Double push sliding bearing is in normal operation, and is injecting a certain pressure in an annular gap between the journal and the bearing aperture and the shoulder end surface and the double-stop bonding end surface. Both "lubricating oil film. When the journal and the bearing aperture and the shoulder end face are in a stable liquid lubrication state, their friction coefficient and wear are minimized, thereby en...
