TIMKEN bearing supports of attached sealed device can effective to makes bearing in does not by outside dirt real invasion of good conditions Xia normal work, but this attached sealed device will increases machinery body of axis to size, on bearing of using and installed brings inconvenience, while attached sealed device of sealed performance often was axis neck and shell body match parts of processing precision and the shaped bit tolerances of effects, for this in structure compact, and sealed requirements strictly of parts.
Common heating methods are:
1. electric heating plate heating put bearings in electric heating plate of the temperature of 100 ° c for a few minutes, this method is most convenient, such as flipping several TIMKEN bearings heat evenly, and high efficiency, size TIMKEN bearings you can use this method.
2. electric furnace heating bearings within the closed automatic temperature control electric furnace heating, heating uniformity, temperature control accuracy, quick heating, suitable for many bearings are heated.
3. the method of induction heating using induction heater can be fast, reliable, and clean the TIMKEN bearing heated to the required temperature, this is especially suitable for tight fit of the inner ring, because heating the inner ring patrons circle heating rarely, so you can more easily on the shaft, seat can also be easily mounted in the hole.
4. light bulbs heating law uses 50W of light bulbs heating TIMKEN bearing, can guarantee heating temperature in 100 ℃ around, smaller bearing can directly placed in bulb Shang, larger bearing can placed bulb of tapered cover within, tapered cover can anti-bulb heat lost, and makes heating uniform tapered cover upper and lower can adjustable bit, in must of range internal energy adaptation heating different size of bearing if used far infrared bulb, attention bulb direction should down, Avoid infrared-rays harmful to the eyes of these light bulbs to energy-saving light bulb heating method applied to small and does not require constant number; to bearing heated occasions, usually light bulbs can also be used for lighting, and does not need any additional equipment.
5. oil slot heating law this is application more wide of traditional heating method, oil slot from bottom 50~70mm Department set metal network, bearing placed online, large bearing to with hook hanging since bearing should not be directly placed Yu slot end of, prevent contact slot end of of bearing parts local heated high, or slot end of precipitation of dirt real entered bearing oil slot heating law of attention points is as follows, should using no corrosion sexual hot stability sexual good of mineral oil, best is transformers oil, And containers should be kept clean of oil capacity of the tanks shall be heated, and TIMKEN bearing size and the amount of oil which, if the container is too small, at the time of continuous operation, a place bearing oil temperature will be dropped soon, the effect on the wrong side.
Shaft tolerances and TIMKEN bearing selection and control: Rotary bearing block after no sense of flexibility. If the display rotation is not flexible, then the shaft size is too large, and decline in tolerance. Bearing life is manufactured, assembled, closely related to the use, you must make every step to make bearings operate best, thus extending the life of TIMKEN bearings.
