Description
Technical field
The present invention relates to mechanical field, more particularly to a kind of material of new making gear.
Background technology
In the design and manufacturing process of machine components product, not only to consider that the performance of material can adapt to the work of part
Make condition, make part durable in use, and require that material has preferable process industrial art performance and economy, to improve part
Productivity ratio, cost is reduced, reduce consumption.If gear material selection is improper, the premature harm of part occurs, or even lose
Effect.Therefore how reasonably to select and the use of metal material is a highly important job.The selection of gear material and gear
Functional reliability, service life, operating efficiency, lubricating requirement etc. it is closely related, in gear passing power and change speed
Exist simultaneously in motion process, between mesh tooth face and roll and sliding friction, the flank of tooth is also pulsed or alternating bending stress
Effect, abrasion, glued and fatigue rupture may be occurred by going back geared surface, therefore it is required that gear has excellent anti-wear performance, anti-connect
Fatigue behaviour and flexural fatigue resistance energy are touched, that is, requires high gear material case hardness, intensity height, core good toughness and hardened layer
It is reasonably distributed.Actually select in should also as needed and use condition for example load, speed, temperature, reliability, quality, precision,
The factors such as price determine gear material selection.
At present, the gear material selection of industry manufacture field is mainly based on steel, including various mild steel, medium carbon steel, high-carbon steel
And steel alloy.And aluminium, magnesium, titanium, copper alloy, cast iron, or even plastics and timber etc. can be used in making gear.Generally, in order to change
Performance that is kind and improving gear material reduces cost, can use chemical treatment, surface Hardening Treatment and Combined Processing etc.
Process for modifying surface.
The content of the invention
The present invention solves the technical problem of a kind of alloy material of new making gear is provided, can have good
Good quenching degree, processing deformation is small, and mechanical property is good.
One aspect of the present invention is：A kind of alloy material of new making gear, mainly oozes alloy
Carbon steel 20CrMnTi mixes with quenching and tempering steel 40Cr carries out carburizing, quenching, temper so that phosphorus content reaches 0.21%-
0.3%, including main alloy element：C, Mn, Cr, Ni, assistant alloy element：Cu, Si, Ti, described alloying element percentage
It is as follows than content：C 0.21~0.28、Mn 0.37~0.45、Cr 0.07~0.11、Ni≤0.05、Cu≤0.03、Si 0.17~
0.23、Ti 0.01~0.1。
Described carburizing, quenching, temper carburizing temperature are 860 DEG C -920 DEG C, and hardening heat is 840 DEG C, tempering temperature
Spend for 120 DEG C -150 DEG C.
The beneficial effects of the invention are as follows：A kind of alloy material of new making gear of the present invention, has good through hardening
Property and low-temperature impact toughness, machining deformation it is small, comprehensive mechanical property is good, heat treatment deformation it is small, suitable at a high speed, load or tool
There is the gear of shock loading.
