Abstract

The invention discloses a heat treatment process for a gear, which comprises the following steps: (A) performing normalizing treatment; (B) performing tempering treatment; (C) performing high-frequency quenching treatment; (D) performing high-temperature annealing treatment. According to the heat treatment process for a gear, through high-frequency quenching of the gear, an aim of high hardness of the tooth surface can be achieved, and the gear has relatively strong pitting resistance and abrasion resistance while the core part has relatively good toughness; after surface hardening, residual contraction stress is generated, and the hardness of the tooth toot is greatly improved; for a gear after high-frequency quenching, gear grinding is required for eliminating deformation, and a high-precision gear can be obtained although the cost is increased.

Description

The thermal treatment process of gear
Technical field
The present invention relates to a kind of thermal treatment process of gear.
Background technology
Along with going deep into of reform and opening-up, national economy has obtained and has increased fast and development, for adapting to this new excellent situation, machinery industry also steps into the new stage of high-tech, high-level efficiency, high life just gradually, geartransmission is one of the most basic mechanically operated type of drive, the maximization of product and first evolve geartransmission has been proposed to upgrade higher requirement, this except from designing, material is suitable for and seeks new approach, the most effective means that the thermal treatment of gear especially must be not fine.
Summary of the invention
The object of this invention is to provide a kind of thermal treatment process of gear.
The technical scheme that the present invention adopted is for achieving the above object: a kind of thermal treatment process of gear, comprises the following steps:
A, carry out normalizing treatment;
B, carry out temper;
C, carry out high-frequency quenching processing;
D, the high temperature anneal.
High-frequency quenching in described step C is processed and is adopted overall high-frequency quenching or single-tooth high-frequency to quench.
The thermal treatment process of a kind of gear of the present invention, a gear high-frequency quenching, can reach the object that tooth face hardness is high, and gear has stronger anti-spot corrosion and abrasion resistance properties, heart portion has good toughness, and surface produces remaining stress under compression and greatly improves tooth root hardness, the gear after high-frequency quenching after sclerosis, need roll flute for eliminating distortion, can obtain high-precision gear though increase cost.
Embodiment
The thermal treatment process of gear, the thermal treatment process of gear, comprises the following steps: A, carry out normalizing treatment; B, carry out temper; C, carry out high-frequency quenching processing; D, the high temperature anneal, high-frequency quenching is processed and is adopted overall high-frequency quenching or single-tooth high-frequency to quench, the thermal treatment process of gear of the present invention, a gear high-frequency quenching, can reach the object that tooth face hardness is high, and gear has stronger anti-spot corrosion and abrasion resistance properties, heart portion has good toughness, and surface produces remaining stress under compression and greatly improves tooth root hardness, the gear after high-frequency quenching after sclerosis, need roll flute for eliminating distortion, can obtain high-precision gear though increase cost.
