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, the surface roughness of workpiece is reduced, and then enhances
The purpose of the service life of gear.
Background technology
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 can cause transmission accuracy, and then generates noise and vibration；Even serious security incident.Japan is to gear
The investigation of failure mode shows that the failure mode of gear is mostly happened at the surface of gear, in other words, gear surface matter
The quality of amount and intensity has far-reaching influence to the service life of entire transmission system.
At present, case-carbonizing, nitridation technique have been obtained for being widely applied in the reinforcing of gear.Case-carbonizing is oozed
Nitrogen technology is to utilize the mode of " heating diffusion " that nitrogen, carbon are goed deep into metal or piece surface, 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, it is impossible to 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

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 costly, safeguard and protect
Foster costly, economic benefit is low.
For laser quenching technology as a kind of new heat processing technique, principle is the laser beam impact matrix using high-energy
Surface undergoes phase transition matrix surface particle, and matrix itself cools down therewith, forms martensite, hard so as to improve the surface of matrix
Degree.Compared to traditional quenching technical, laser quenching can form more uniform hardened layer in matrix surface, and matrix deformation is small,
Suitable for the higher place of requirement on machining accuracy.But laser quenching technology is disadvantageous in that its high processing costs, it is desirable that
There are special technical operation personnel to 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 operation 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 carries
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
Be processed.
