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.

軸承加熱器，其優(yōu)點是： ">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

軸承加熱器由工頻感應加熱主機與電器控制系統(tǒng)組成，其結(jié)構(gòu)為可移動輪式或固定臺式兩種可供選擇，對于直徑大、質(zhì)量重的軸承可以選用“多功能感應加熱器”。">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

軸承加熱器采用渦流感應加熱原理，軸承在加熱過程中與主機的鐵芯組成一閉合的磁回路，電流會在軸承內(nèi)部形成螺旋形的流動路線，由于電流流動而產(chǎn)生的熱量就都被軸承金屬本身吸收，通過主機的磁力線產(chǎn)生渦流而被快速加熱。">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.
