Embodiment Construction

[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0041] Such as Figure 1-3 As shown, a gear induction hardening equipment, which includes a profiling induction coil 1, a first support plate 2 for supporting the gear and a driving device, the profiling induction coil 1 has a contour of a full ring gear structure to match the The gear 13 is meshed, and the profiling induction coil 1 imitates the outer contour of the gear. The driving device drives the profiling induction coil 1 or the first support plate 2 to move up and down, so as to realize the relative movement between the profiling induction coil 1 and the gear in the up and down direction.

[0042] In this way, the main innovation of this case is to add a driving device for the profiling induction coil to realize the scanning quenching of the gears in the up and down direction through the profiling indu...

Abstract

The invention discloses gear induction quenching equipment and technology. The equipment comprises a profiling induction ring, a first supporting disc used for supporting a gear and a driving device,wherein the profiling induction ring is provided with a profile of a whole gear ring structure so as to mesh with the gear, and the driving device drives the profiling induction ring or the first supporting disc to do up-and-down lifting motion. The equipment solves the problems of poor profiling effect, low production efficiency and high manufacturing cost of induction double-frequency quenchingequipment in the prior gear induction quenching technology.

Description

technical field [0001] The invention relates to the technical field of metal surface quenching, in particular to a gear induction hardening equipment and process. Background technique [0002] The gear is induction hardened to make it have a profile hardened layer, which can ensure the high quality and long life of the gear. The existing gear induction hardening methods mainly include the following types, each of which has corresponding defects: [0003] The first method, the inductor is a single-tooth shape, and the single-tooth structure adopts "tooth-by-tooth quenching" or "interval quenching" induction hardening; it is usually used for quenching of large and medium gears, which can form uniform profile hardening on the gear surface Layer, the disadvantage is that each single tooth is quenched one by one, the efficiency is low, time-consuming, energy-consuming and labor-intensive. [0004] In the second method, the inductor is an ordinary induction coil, and it is harde...
