The ways of achieving co-use for aligning roller bearings

1. Electric heating plate bearing heating method. It is placed on the electric hot plate temperature of 100 ℃ for a few minutes. This method is most convenient, such as reversing it a few times that can make the bearing heated, and the efficiency is high, the big minor heart roller bearings can use this method.

2. The electric furnace heating method. It puts the bearing in the sealed automatic temperature control electric furnace for heating, uniformly heating, accurate temperature control and fast heating, which is suitable for the occasions where many bearings are heated in a batch.

3. The induction heating method. It uses induction heater to heat the aligning roller bearing to require temperature quickly, reliably and cleanly. This is especially suitable for the situation where the inner ring is tightly coupled.

4. Light bulb heating heating method. It uses 50w bulb spherical roller bearings, which can guarantee the heating temperature about 100 ℃. The smaller bearing can be directly on the bulb, and larger bearing cone enclosure may be placed on a light bulb. Conical cover can prevent heat losses. Light bulbs and uniform heating cone cover can be adjusted up and down. Heating range can adapt to different size of bearing using infrared light bulb. Paying attention to the direction of light bulbs should be down, in order to avoid this kind of bulb of infrared radiation which is bad for the eyes. Energy-saving bulb heating method is suitable for small and often do not need. When the bearing is heated, the bulb can be used for lighting at ordinary times. In addition, no other equipment is needed.

5. Oil groove heating method. This is a widely used traditional heating method. The bottom of the tank from 50 to 70 mm uses in the metal mesh, with bearing on the Internet. Large bearing should use to hoist hooks in the bearing and should not be placed directly on the bottom of the channel, in case of contacting with the bottom of the channel bearing parts of the local heat which is too high or the bottom of the channel deposition of dirt into the bearing. Oil tank heating method of key points are as follows. It should use no corrosive thermal stability good mineral oil, transformer oil, and it is best to oil and the capacity of the container should be kept clean. If the container is too small, in continuous operation, it put the bearing oil temperature will drop quickly, and the effect is bad.
