Abstract
The invention discloses a heat treatment technique for a large-load gear. The heat treatment technique for the large-load gear is characterized by comprising the following steps that A, high-frequency induction heating is conducted, specifically high-frequency induction heating is conducted at the temperature of 860-900 DEG C, and heat preservation is conducted for three hours; B, quenching is conducted, and specifically the gear subjected to induction heating is placed in water to be quenched for one hour; and C, tempering is conducted, specifically the gear is placed in a tempering furnace to be tempered, the temperature of the furnace is increased to 590-625 DEG C, heat preservation is conducted for five hours, and the gear is discharged out of the furnace and air-cooled to the indoor temperature. According to the heat treatment technique for the large-load gear, heating is more complete, and thus the tenacity of the interior of the gear is improved.
Description
Technical field
The present invention relates to a kind of big load gear and process technique.
Background technology
If existing gear pressure when work is excessive, or practicality is comparatively frequent, it is easy for causing the damage of gear, making between gear can not toe joint be together well, and, gear all in inside, also bad replacing, this results in the application of existing gear, and gear has increasingly higher requirement.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of big load gear heat treatment technique of offer, and the heating of this Technology for Heating Processing is more complete, makes the toughness of gear internal improve.
For achieving the above object, the invention provides a kind of big load gear and process technique, it is characterised in that comprise the steps:
A, high-frequency induction heating: 860～900 DEG C of high-frequency induction heating, be incubated 3 hours；
B, quenching: the gear after sensing heating is put in water and quenches, 1 hour time；
C, tempering: being put into by gear in tempering furnace and carry out temper, furnace temperature rises to 590-625 DEG C, be incubated 5 hours, and air cooling of coming out of the stove is to room temperature.
The invention has the beneficial effects as follows: present invention heating is more complete, makes the toughness of gear internal improve.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of big load gear heat treatment technique, it is characterised in that comprise the steps:
A, high-frequency induction heating: 860～900 DEG C of high-frequency induction heating, be incubated 3 hours；
B, quenching: the gear after sensing heating is put in water and quenches, 1 hour time；
C, tempering: being put into by gear in tempering furnace and carry out temper, furnace temperature rises to 590-625 DEG C, be incubated 5 hours, and air cooling of coming out of the stove is to room temperature.
The heating of this Technology for Heating Processing is more complete, makes the toughness of gear internal improve.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
