Abstract

The invention relates to a machining method for a cross-scale staggered embedded type self-lubricating gear surface. The machining method comprises the four main machining steps of macro-scale machining, self-lubricating material embedded filling, gear surface grinding machining and micro-scale machining. According to the machining method, a cross-scale self-lubricating interface is formed on thegear surface by arranging the interface according to a certain rules and combining the characteristics of a self-lubricating material through an electrochemical machining method, a laser cladding technology and a laser microtexture technology, the lubricating requirement of a gear under the oil-free or oil-lack condition is met, and the gear surface has the enough hardness and smoothness. According to the machining method for the cross-scale staggered embedded type self-lubricating gear surface, a common gear can be machined into a cross-scale staggered embedded type self-lubricating gear, anda foundation is laid for practical application of the self-lubricating gear.

Description

technical field [0001] The invention belongs to a gear surface processing method, in particular to a processing method for a cross-scale interlaced embedded self-lubricating gear surface. Background technique [0002] At present, self-lubricating gears mainly focus on gear structure design and coating tooth surface design, which can be divided into matrix oil storage type self-lubricating gears and coating type solid self-lubricating gears. However, the base oil storage type self-lubricating gear cannot achieve the self-lubricating purpose in the case of no oil or lack of oil, and when the gear is running at high speed, the lubricating oil will be thrown out so that the lubrication purpose cannot be achieved, while the coating type solid self-lubricating gear is in the Under the conditions of high speed, heavy load and long-term operation, the coating will fall off and the self-lubricating properties will be greatly reduced. For this reason, the applicant invented "a multi-...
