According to different methods, it can be divided into trolley-type bearing inner sleeve disassembly heater and hand-held bearing inner sleeve disassembler, which can be determined according to the space in your workshop and the convenience of operation. It is widely used in steel metallurgy, railway locomotive and other industries. Users are welcome to call for consultation
●Working purposes

The induction heater for disassembly and assembly of the bearing inner sleeve (referred to as the bearing inner sleeve disassembly and assembly heater) is used in four-row and double-row short cylindrical rollers. Installation and disassembly of sub-bearing inner sleeves and labyrinth rings.
● Working principle

The bearing inner sleeve disassembly and assembly heater uses the electromagnetic induction heating principle to evenly heat the bearing inner sleeve and labyrinth ring from the outside to the inside, so that the bearing inner sleeve and labyrinth ring Thermal expansion occurs in an instant. When the inner hole expansion exceeds the shaft diameter interference assembly amount, the bearing inner sleeve and labyrinth ring can be successfully removed or installed.
● Structural features

The bearing heater is composed of an induction heater host and a control box.

The induction heater is mainly composed of an electromagnetic coil and a stainless steel and epoxy plate shell. When the induction heater continues to work and the electromagnetic coil itself generates heat and heats up, an exhaust fan can be used to blow air on the main coil of the induction heater for forced cooling, thus extending the service life of the sensor. The induction heater adopts a portable handheld type and a center height adjustable type (it is recommended that users make their own simple derricks according to the convenience of the use location and the height of the roller from the center of the ground).

The control box mainly controls the time for the sensor to install and disassemble the inner sleeve of the bearing. The control method adopts time control, and the heater stops heating when the time is up. In addition, the control system is equipped with a self-healing compensation capacitor, which is used to improve the power factor of the sensor and instantaneous demagnetization (
