Description

Inductor for main bearing of slewing bearing

Technical Field

The utility model belongs to the technical field of induction heating, concretely relates to slewing bearing is inductor for base bearing.

Background

At present, the known inductor for main bearing raceway induction heat treatment is divided into split machining or integral machining, split machining needs at least three times because the main bearing needs to be machined in more positions (at most five different positions need to be machined), not only energy is wasted, but also the probability of product badness is greatly increased easily due to multiple times of quenching, integral machining is high in magnetic field density at the corners of a workpiece, heating efficiency is high, the temperature is easily overheated after induction heating, quenching cracks are easily generated, the general size of the integral inductor is large, the influence strength of a magnetic field is poor during machining, and heating is uneven.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a slewing bearing is inductor for base bearing through five positions of simultaneous processing, reduces work piece corner heating efficiency, can guarantee energy-conserving quick processing, can guarantee again that product quality stabilizes advantages such as overheated can not appear in the corner.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model relates to a slewing bearing is inductor for base bearing, including the mounting panel, preheat induction coil, heating induction coil, magnetizer, induction coil connection optimization device, the electric current gets into through preheating effective circle influent end, flows the section backward flow from preheating effective circle, and effective circle connection optimization device can make the corner the same with other position heating efficiency, adds the enhancement version of unique design and can strengthen inductor intensity, and the heating process in-temperature is even.

Compared with the prior art, the beneficial effects of the utility model are that: this device reduces work piece corner heating efficiency through five positions of simultaneous processing, can guarantee energy-conserving quick processing, can guarantee again that product quality stabilizes advantage such as overheated can not appear in the corner.
