How to prevent the ball machine straight flange bearings from friction heat?

Machine tool movement straight flange bearing is mainly used to support the rotor rotation. Under linear bearing flange movement will produce a lot of friction heat, high speed rotation of the movement for straight flange bearing during manufacturing has a relatively high degree of finish, and avoid such as flange movement by the straight line bearing overheating caused by friction, as well as accidental damage of the accident. In the actual production, the straight flange bearings are suitable for all kinds of rotational support movement. Machine tools in the straight flange bearing used for connecting motor and rotor, the rotor and a hammer, especially when the machine has high hardness, need to increase the speed to make a big impact. Straight flange movement bearing overheating and overheating for several reasons: 1. Straight flange motor bearing surface roughness can be affected. Straight flange bearing surface smooth movement. Roughness can usually reach 1. 6. Other according to the requirements of different will have different roughness. If the roughness of accidental damage, the two straight flange movement and the height of the bearing is not uniform. Different heart or motor rotor and rotor of the machine tool, this will lead to additional straight flange movement bearing load, cause the straight flange bearing overheating movement. In this case, must immediately stop the machine to eliminate the fault and avoid straight flange bearing early damage of the movement. By metal scratch and collisions with other components, for example, can increase the straight flange movement bearing rotates the friction and heat further. 2. Straight flange movement of bearing lubricating oil too much, too little or aging is straight flange bearing overheating and damage the main reason for the movement. Therefore, must according to the requirements of the book to use quantitative filling of lubricating oil. Usually, the lubrication accounted for 70% of linear bearing flange movement space. 80%, too much or too little is not conducive to straight flange bearing lubrication and heat transfer. No lubrication and maintenance measures. Straight flange movement bearing lubrication is necessary for a long time. Normally, every time they open will be lubrication, linear bearing flange movement can prolong its service life. 3, feeding too much, the main reason is that the feeding device feeding speed regulation is not good, hello feed rate is too large, machine capacity is too small, can't timely shattered, blocking crushing chamber, the rotor resistance increases, lead to straight flange bearing overheating movement. 4. Long-term work overload. In general, in order to catch up with the progress of the production of high strength, machine tool can not timely maintenance, and will continue to heat up and burst. 5. Straight flange bearing cover and shaft is too tight. If the straight flange bearing and shaft too tight or too loose, linear bearing flange movement will overheat. Once appear this problem, during the period of equipment running friction and obvious oscillation will occur. Linear bearing flange movement should be on the machine to be removed, friction parts should undertake nap, and then reassembled according to need. Solution: once the straight flange bearing roughness are destroyed, linear bearing flange movement be replaced immediately, can't be used again. Second, to linear bearing flange movement maintenance lubrication, try to avoid high strength production for a long time. Finally, arrange the production process, and according to the output of the machine tool control to reduce the feed rate of feed rate.
