In 1, and point

There are a lot of bearing is mounted in the process of damage, improper heating method is one of the important reasons. Such as the use of welding tool is heated, will cause the deformation of journal bearing; the fire heating, bearing two heated unevenness; uses the oil bath heating, due to unclean and the bearing oil pollution, noise increases; the oven heating, it is a waste of time. As for beating the installation, bearing more easily damaged.

轴承加热器，其优点是： ">Now the latest international generic technology is the use of bearing heater, the utility model has the advantages of:

High performance high heat efficiency, fast heating speed, improve the work efficiency and the assembly speed.

Convenient out-of-the-box, without preheating, to set the time automatically jump off, convenient and quick.

Reliable and uniform heating, equal expansion, after heating the bearing temperature of less than 1 degrees.

Safety built-in over heat protection system, long-term continuous use, suitable for assembly line operation, reliable operation.

Environmental protection and low energy consumption and zero emission, is conducive to the environment and the health of staff.

Automatic demagnetization demagnetization, after heating the bearing residual magnetism of less than 3 Gauss, in line with the ZQ33-85 standard.

2, node structure

轴承加热器由工频感应加热主机与电器控制系统组成，其结构为可移动轮式或固定台式两种可供选择，对于直径大、质量重的轴承可以选用“多功能感应加热器”。">Bearing heater by induction heating machine and an electrical apparatus control system, its structure is a movable wheel or fixed table two kinds of options, for big diameter, heavy weight bearing can be chosen " multifunctional induction heater".

3, work principle

轴承加热器采用涡流感应加热原理，轴承在加热过程中与主机的铁芯组成一闭合的磁回路，电流会在轴承内部形成螺旋形的流动路线，由于电流流动而产生的热量就都被轴承金属本身吸收，通过主机的磁力线产生涡流而被快速加热。">Bearing heater using eddy current induction heating principle, bearing in the process of heating and hosts the core to form a closed magnetic circuit, the current will be in the bearing to form a spiral flow path, because the current flow and heat generation were bearing metal absorbs, through the host of the magnetic line of force to generate eddy current and be heated quickly.
