Description
Technical field
The present invention relates to gear tooth surface strengthening technologies, and ultrasonic deep-rolling technology is combined with traditional profiling technique,
A kind of ultrasound-enhanced device of the gear based on copying principle is designed, reduces the surface roughness of workpiece, and then reach enhancing
The purpose of the service life of gear.
Background technique
According to the transport characteristics of gear, common failure mode has spot corrosion, abrasion, gluing, fracture etc..These destroy one
Denier forms the decline that will cause transmission accuracy, and then generates noise and vibration；Even serious safety accident.Japan is to gear
The investigation of failure mode shows that the failure mode of gear mostly occurs on the surface of gear, in other words, gear surface matter
The superiority and inferiority of amount and intensity has far-reaching influence to the service life of entire transmission system.
Currently, case-carbonizing, nitridation technique have been obtained for being widely applied in the reinforcing of gear.Case-carbonizing, infiltration
Nitrogen technology is that nitrogen, carbon are goed deep into metal or piece surface in the way of " heating diffusion ", forms surface alloying layer.Nitriding
Technology can obtain preferable surface quality, have the characteristics that hardness is high, wearability is good, deformation is small, but the production cycle is long, cost
Height, nitriding layer thin and fragile are big, cannot bear too big contact stress and high shock loading.Carburizing tech can obtain deeper
Infiltration layer, bearing capacity is strong, but temperature requirement is high, deformation is big, surface it is of poor quality.Shot Peening Technology, principle are to base
Body emits High-velocity Projectiles, applies sufficiently large impact force, so that matrix surface be made to absorb more energy, and generates plasticity change
Shape forms residual compressive stress, improves surface property, achievees the purpose that prolong the service life.But the matrix surface light after strengthening
Whole degree is poor, generally requires and carries out subsequent finishing.This production cost just improved.And due to the high-velocity particles direction of motion
Uncertainty, the surface stress after reinforcing is uneven, easily tooth surface generate microfissure, damage the gear teeth service life.
The principle of plasma spray technology is that sprayed on material is heated to and dissolves or half melting state, then will with certain speed
Its jet deposition forms coating to matrix surface.In terms of gear reinforcing, plasma spraying technology has reason using relatively broad
The processing effect thought can effectively improve tooth face hardness, reduce surface roughness, but thermal spraying apparatus is more expensive, and maintenance is protected
Support costly, economic benefit is low.
For laser quenching technology as a kind of heat processing technique, principle is the laser beam impact matrix table using high-energy
Face undergoes phase transition matrix surface particle, and matrix itself cools down therewith, martensite is formed, to improve the surface hardness of matrix.
Compared to traditional quenching technical, laser quenching can form more uniform hardened layer in matrix surface, and matrix deformation is small, is applicable in
In the higher place of requirement on machining accuracy.But laser quenching technology is disadvantageous in that its processing cost height, it is desirable that has specially
The technical operation personnel of door support, and the technology destroys the roughness of matrix surface to a certain extent.
In recent years, with the research that deepens continuously of ultrasonic technology, ultrasonic technology has obtained extensively in every field
Application, among these just include ultrasonic deep-rolling technology.The working principle of ultrasonic deep-rolling technology is the height generated using ultrasonic tool
The mechanical oscillation of frequency high-energy, with higher speed impacts workpiece surface, workpiece surface absorbs energy, and occurs a degree of
Plastic deformation generates processing hardening to achieve the purpose that reinforcing, while can reduce the roughness of workpiece surface, and then reach and mention
High workpiece surface quality enhances the purpose of service life.But existing ultrasonic deep-rolling technology is served only for outer circle, plane etc. at present
The processing hardening of very regular contoured surface, can not be effective for involute gear and other more complicated outer surfaces
Carry out process.
