The Structure & Working Principle of Bearing Induction Heater
The bearing induction heater is a kind of air-cooling frequency induction heating device, which is composed of induction heating main control, yoke steel, temperature controller & sensor and other accessories. The purpose of heating the bearing is to cause the bearing to produce thermal expansion, so that the bearing can be smoothly sleeved on the shaft.
In fact, the working principle of bearing heater is applied electromagnetic induction heating, which is actually the use of magnetic fields. When we put the bearing on the yoke steel, the circuit is closed and a magnetic field is formed. The heated work piece is a equivalent to a resistance. The current in the magnetic field will accumulate every time it passes through the resistance. As a result, the workpiece is also heated.
The Advantage & Feature of Bearing Induction Heater
- Safe, clean and environmentally friendly
Traditional methods, such as live roasting, oil bath, oven roasting, are not only costly but also produce coke smoke, odor and waste oil. The application of induction heaters can replace traditional methods to create a safe and clean working environment.
- Fast and without damage
After heating, the bearing expanded outward in the cylindrical direction, which can avoid damage during installation. Induction heating is an excellent heating method, and it does not need to be preheated. The bearing can be heated to 120°C in a few seconds or minutes without damaging the pre-lubrication.
- Rational design
In order to meet the requirements of the industrial environment, the design concept of induction bearing heater for sale is modernization, rationalization, easy operation and high durability. Portable bearing heater is a convenient heater to facilitate the on-site use.
