Temperature effect on NSK insert ball bearing unit installation considerations

Induction heating principle: induction insert spherical bearing heater can be compared with the transformer, its working principle is to put a large number of turns of the primary coil and a less number of turns of the secondary coil is installed on the same core. The input and output voltage ratio is equal to the ratio of the coil number of turns, at the same time energy remains constant. Therefore, the secondary coil under the condition of low voltage high current. NSK bearings for induction heater is a secondary coil short-circuit single-turn, under the condition of low voltage by large current, by making a lot of heat. Heater itself and yoke will keep at room temperature. Because of this heating method can detect the current, so the bearings will be magnetized. To NSK bearing when it is important to ensure that the demagnetization, make it in the process of operation will not absorb metal magnetic crumbs. All of the induction heater has function of automatic degaussing. Bearing installation last should undertake clearance adjustment. Clearance value should be used according to different conditions and cooperate with the amount of interference and specify the size. When necessary, shall be tested to determine. 1. First of all, the axis of rotation or shell, to see if it detects something unusual. 2. Then, start to be insert ball bearing unit computer application load. Under the condition of low speed rotation in observation, gradually increase the speed and load, at the same time to stop any noise, vibration and temperature. 3. If there is anything unusual is found in the process of operation, stop the computer and perform the inspection. Review of unusual noise or noise levels should be produced by others properly installed and NSK bearings under the condition of normal operation of sound familiar work. Check the bearing, don't let the set-contained spherical bearing exposure to pollutants or moisture environment. If the job is interrupted, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of NSK bearings, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check the bearing of the orbit plane, retainer and beads. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. In regular maintenance downtime period change insert spherical bearing NSK bearing damage than the selected into a sudden stop loss is much more economical.
