INA clutch bearing running on several matters needing attention

INA bearing single turns after the installation can use first hand plate rotation. Check the rotation of the clutch bearing flexibility, if not the following anomalies, the examination of the dynamic operation again. Bearing grinding the instantaneous high temperature can make the surface of a certain depth ( 10 ~ 100海里) Be heated to a temperature higher than the workpiece temperature tempering heat. In the absence of austenitizing temperature reached, with the improvement of heated temperature, the surface will produce one by one and heating temperature corresponding to the organization transformation, or high temperature tempering tempering hardness. The higher the heating temperature and hardness of the decline is more severe. Bearing most working temperature at 200 ℃, and tend to be higher, if not through strong cooling, the temperature will continue to rise and the strength and hardness of the INA bearing is adverse, clutch bearing once losing their ability to keep accurate shape, will aggravate the friction and make the temperature rising rapidly, resulting in a loss of material strength and hardness and make further bearing failure quickly. Because of the bearings is sensitive to wear, and prone to wear debris, if not timely out of bearing, will also cause a vicious cycle, fast bearing failure. Bearing lubrication of the task must be effectively lubricant and submit it to the surface of INA bearings in motion, and the heat away from the bearing, and abrasive dust or dirt removed from the bearing. Rolling bearing cage can be divided into punching cage and entity cage. Rolling bearing at work, heat and wear caused by sliding friction bearing, especially under the condition of operation, due to the effect of centrifugal force, accelerate the friction and wear with fever, a bracket will be caused serious burns and fracture, the clutch bearing cannot be used properly. Cage damaged occupy large proportion in the bearing failure modes. In the failure reasons of cage, cage material quality is one of the main reasons. INA bearings instantaneous high temperature heat the workpiece surface layer when the grinding area to the austenitizing temperature ( Ac1) Above, the layer of austenitizing group in the subsequent cooling process, the quenching into martensite structure anew. Where the secondary hardening burns of workpiece, the second time hardening layer must be under very low temperature tempering hardness layer. 1, normal use after one year should be a change in 2 # spindle oil and coarse fine filter. 2, the normal use of pump station to add oil must be 3 layer filter for silk cloth. 3, the spindle pulley, wheel loading and unloading must be in pump station stops working condition. The spindle under the conditions of static pressure oil float stops. It's not damage and static pressure imported bearing spindle. 4, grinding wheel spindle before work can see pump station and grinding head hydrostatic pressure within the scope of the standard. 5, equipment downtime, must stop the grinding head motor first, after waiting for grinding wheel stop, then turn off the pump station, otherwise easy to damage the grinding head. 6, in pumping station of any parts, must first to removing the high pressure oil hose connection, after changing the parts, oil circulation 15 to myself 20 minutes ahead into the tubing can be connected to grinding head, thus ensure the into the grinding head spindle oil is super clean spindle oil after fine filtering. Doing so will extend the life of the used for static pressure spindle.
