Bearing heater structure and working principle:
Bearing heater frequency induction heating device referred to as the host and control equipment by dry from the cold work.
 
Heater works:
1, the short-circuit heating: Host for a special structure of the transformer, the movable yoke to wear sleeve bearings or other workpiece is heated directly. Work, on the host power supply, the workpiece (equivalent to the secondary winding) induced in the short-circuit current to be heated.
Installation and commissioning
2, the yoke is placed to the end surface of the core of the host.
3, check the wiring of the plug and socket are the same, the ground should be good, and then insert the plug into a power outlet on the control switch.
4, the function selection switch hand control position, close the power, then the red indicator light.
5, press the start button, the host is powered when the green indicator lights up red put out; press the stop button, the red light green light extinguished. At this point, the end of the debugging can be put into use.
 
Operating procedures:
1, according to the inner diameter of the bearing, and select the corresponding yoke (see Table 2), the string will be put on the bearing yoke is placed to the host core end surface should be consistent flat.
2, in the heating process, the point thermometer to measure the bearing inner ring side at the plane of temperature rising. When the temperature rise to meet the requirements, the spotted count, stop heating, remove the yoke, remove the bearings can be assembled.
3, the continuous heating of the same specifications bearings, the function select switch when the control position, set the heating time, when the bearing is heated to the set time automatically turn off the power.
4, after the completion of the function select switch to the stop position, cutting position.
