Bidirectional thrust ball bearing temperature check processing method

Bidirectional thrust ball bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. Usually, the temperature of the bidirectional thrust ball bearing with bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the working temperature of bidirectional thrust ball bearing, and implement e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the bidirectional thrust ball bearing in more than 125 ℃ temperature for a long time even move to reduce the bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. The using temperature of bidirectional thrust ball bearing and the bearing of the heat treatment process, the conventional heat treatment process of tempering temperature is 150 degrees, the highest use temperature bearing general requirements within the scope of the 120 degrees, if you have special requirements, can be used in a 200, 250 degrees or higher tempering temperature, the temperature can reach 170, 230 degrees or higher. Need to check on the machine running state, the bidirectional thrust ball bearing is the focus of attention, and prepare to thoroughly check scheme has become more and more important. Because it is the most important of all components of the rotating machinery condition monitoring, in order to prevent bearing damage, to prevent unplanned maintenance equipment downtime bearing damage caused during the period of early detection of an important component part of the home. But not all the machines are equipped with the advanced equipment. In this case, the machine operators or maintenance engineer must adhere to the bearing fault signal alarm. Bidirectional thrust ball bearing in the process of running, sometimes between bearing surfaces into hard foreign matter or foreign solid particles or abrasive dust on the surface of the metal, it can cause furrow is bearing abrasion, inside these hard foreign body through into the bearing lubrication medium, with the continuous operation of bearing, the local friction heat production, easy to cause the friction surface phenomena, local micro welding deformation and friction of partial melting may even happen, finally cause occlusion phenomenon. Bearing faults have defects and overload causes two factors, when the loads more than material strength limit rupture caused by parts called overload fracture, the bidirectional thrust ball bearing can also occur during the operation of overheating organizations and local burns and other defects, defect caused by fracture. Generally we can through the instrument to monitor belong to which kinds of fracture, the majority of cases, most bearing fracture failure for overload caused by failure.
