Abstract
The invention discloses a heat treatment process for a gear; the heat treatment process comprises the following steps: (A) performing normalizing treatment; (B) performing tempering treatment; (C) performing high-frequency quenching treatment; and (D) performing high-temperature annealing treatment. According to the heat treatment process for the gear, through high-frequency quenching of the gear, a purpose of high hardness of the tooth surface can be achieved, and the gear has relatively strong pitting corrosion resistance and abrasion resistance while a core part has relatively good toughness; after surface hardening, residual contraction stress is generated, and the hardness of a tooth root is greatly improved; and for a gear after high-frequency quenching, tooth grinding is required for eliminating deformation, and a high-precision gear can be obtained although the cost is increased.
Description
Technical field
The present invention relates to the Technology for Heating Processing of a kind of gear.
Background technology
Along with going deep into of reform and opening-up, national economy achieves and quickly increases and development, for adapting to this new excellent situation, machinery industry also steps into the new stage of high-tech, high efficiency, high life just gradually, gear drive is one of mechanically operated most basic kind of drive, gear drive is proposed the requirement that renewal is higher by maximizing and first evolving of product, and this is suitable for except seeking new approach except, material upper from design, the maximally effective means that the heat treatment of gear especially must not be fine.
Summary of the invention
It is an object of the invention to provide the Technology for Heating Processing of a kind of gear.
The Technology for Heating Processing of the present invention the technical scheme is that a kind of gear for achieving the above object, comprises the following steps:
A, carry out normalized treatment；B, carry out temper；C, carry out high-frequency quenching process；D, the high temperature anneal.
High-frequency quenching in described step C processes and adopts overall high-frequency quenching or single-tooth high-frequency quenching.
The Technology for Heating Processing of a kind of gear of the present invention, gear high-frequency quenching, the purpose that tooth face hardness is high can be reached, and gear has stronger anti-spot corrosion and abrasion resistance properties, heart portion has good toughness, produces remaining stress under compression and be greatly improved tooth root hardness after surface is hardened, the gear after high-frequency quenching, roll flute is needed, though increasing cost but high-precision gear can being obtained for eliminating deformation.
