Install the bearing by heating
The installation force required to install the bearing or ring workpiece increases rapidly as the bearing size increases. Due to the installation of the requirements of the larger bearing is not easy to push the shaft or into the bearing seat. Therefore, the bearing or bearing or or ring-shaped workpiece needs to be heated before installation.
The principle of induction heating
Can be induction bearing heater compared with the transformer, it works by a number of turns more primary coil and a smaller number of secondary coil mounted on the same core. The input and output voltage ratio is equal to the ratio of the turns of the coil, while the energy remains constant. As a result, the secondary coil generates a high current at low voltage. For the Yangtze tool induction heater, the bearing is a short-circuit single-turn secondary coil, under low AC voltage conditions through the high current, resulting in a lot of heat. The heater itself and the yoke are kept at room temperature. Since this heating method can induce current, the bearing is magnetized. It is important to ensure that the bearing after the demagnetization, so that in the course of the operation will not suck metal chip. All induction heaters have automatic demagnetization.
Heating installation
The temperature difference between the bearing and the bearing mounting position depends on the level of interference fit and the bearing size. Normally, the temperature of the bearing is higher than the temperature of the shaft by 80 to 90 ° C (144 to 162 ° F) is sufficient for the installation. But absolutely can not let the bearing heating temperature exceeds 125 ℃ (257 ℉), because when the bearing material will occur metallographic transformation, resulting in changes in diameter or hardness. Must avoid local overheating, in particular, can not use open flame heating bearings. Wear protective gloves when installing heated bearings. Use lifting (lifting) machinery to facilitate installation. Push the bearing along the shaft to the mounting position so that the bearing remains stationary and pressed until it fits securely. The Yangtze tool offers an inductive bearing heater with a thermostat with adjustable thermostat to meet all the needs of the installation in general.
Why use induction bearing heaters?
Inductance heating is an advanced, fast, controlled heating method. Inductive heating is safe and environmentally friendly in terms of the relative heating of the heating stove, the heating of the oil bath, the fogging of the torch, the waste of oil and the harmfulness to human health. advantage.
Suitable for bearings and other parts
The induction heater is versatile and can be used as a heating for a ring workpiece such as bearings, gears, mechanical bushings and fittings. As we all know, the correct installation can extend bearing life. Controllable inductive heating can prevent unnecessary damage and can maintain the original pre-lubrication, which is ideal for mounting with sealed bearings.
Heating safe and controllable.
Bearing heaters, gear heaters, induction strippers, ring gears are the principle of inductive heating production.
In the heating process, the numerical control components can provide optimal control, automatic selection of effective power supply, to ensure uniform heating, fast, no additional steps, in the heating process will not explode, will not fade or the surface of the village material depression The CNC parts can provide a shelf life of three years.
reliable quality
The induction heater is proven to be reliable, and due to the excellent cooling of the sheet, the electronic components can be used continuously. The rugged and easy to use design makes the heater safer and is suitable for continuous operation in industrial environments.
