Install the method to check with roller bearing of cente adjusting of ZWZ Wafangdian:
1.The bearing operates and checks small-scale machinery and can be rotated by hand, in order to confirm whether the roller bearing of cente adjusting is rotated smoothly. It is not smooth to have operation incurred because of foreign matter, scar, impression to check the project; Because it is bad to install, the mount pad is processed badly but the force moment of production is unstable; Cause the force moment of the roller bearing of cente adjusting to be too big, etc because the backlash passes little, installation error, sealed friction. Have unusual can power turn round at the beginning. 2.The bearing power is operated and can’t be rotated to check large-scale machinery manually, so idler cuts off motive force immediately after starting, machinery dallies, check the roller bearing of cente adjusting has vibrationless, noise, gyro unit that keep in touch etc., after being unusual, enter motive force and operate. Motive force operates, begin with low speed of idler, the amount to the condition made of improvement slowly operates. The intersection of cente adjusting and the intersection of roller and bearing it checks the item to be in the trial run: Are there unusual stereo, change, leakage of lubricant or allochromasis in the temperature,etc.. 3.The bearing temperature can generally be inferred according to the outside temperature of the pedestal while checking the temperature. But utilize the temperature of the outer lane of roller bearing of cente adjusting of direct measurement of oil hole to be more accurate. Rise gradually since operating, usually temperature stabilization after 1~2 hours. If it is bad to install, the bearing temperature will rise sharply, the high temperature of becoming abnormal. 4.The bearing rotates with auscultator,etc. and checks if the bearing finds stronger metal noise, abnormal noise, irregular sound,etc. while checking, rity bading rotates with auscultator,etc. and checks if the bearing finds stronger metal noise, abnormal noise, irregular sound,etc. while checking,
