TIMKEN bearing plane daily care attention to matters

TIMKEN bearing assembly has been completed, in order to check the device correctly, to stop check. Small mechanical energy enough hand rotation, to confirm whether it can rotate smoothly. Check project has formed as a result of foreign bodies, scars, indentation seized up, due to the bad device, device processing torque instability as a result of the bad, because the clearance is too small, installation error, seal friction and provoked torque is too big, and so on. If there is no abnormal can start power operation. Large machinery from manual rotation, so the no-load start immediately after cut off the power, machine idle, for vibration, noise, rotating parts can have contact and so on, confirmed after no abnormalities, into power operation. Dynamic operation, from the beginning of no-load speed, slowly progress to the rated operating conditions. Test run to check the items, whether there is abnormal sound, plane bearing temperature changes, smooth agent leaked or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Temperature, ordinary can be based on speculation and the outside of the bearing temperature. But the application of oil hole directly measure the temperature of the TIMKEN bearing outer ring more accurately. Bearing temperature, from the beginning of operation gradually rise, usually 1 ~ 2 hours after the temperature stability. If the poor bearing assembly, the temperature will rise sharply, abnormal high temperature. For reasons such as smooth agent device, bearing clearance is too small, too much bad, seal installation too much friction, etc. At high speed, structure, the choice of the ways of smooth error, etc. As well as the reason. 1, adhere to the bearing and the surrounding clean. Even the eyes can't see the little dust, also can bring bad influence to TIMKEN bearings. So to stick around, clean the dust from invading plane bearing. 2, be careful careful use of bearing in the use of giving TIMKEN bearing intense impact, will produce scar and creasing, become the cause of the accident. Serious situation, can crack and fracture, so must pay attention to. 3, using the appropriate tools to prevent operation with existing tools to replace, must use the appropriate tools. 4, pay attention to surface bearing rust bearing operation, why hand sweat will become rusty. To pay more attention to operation with clean hands, it is better to try to bring gloves. Understand the use of the TIMKEN bearing way will have the effect of get twice the result with half the effort, it is very important. When bearing full mechanical parts that used the smooth or oil demand by smooth oil cooling, oil bearing should be smooth. In bearing heavy load and high speed, or with external heat comes in, there may be cooling request. The trace smooth method is adopted, for example, drip is smooth, smooth or oil mist of oil and gas is smooth, can keep stirring oil loss and bearing friction are quite small. When using the air for the carrier, can be directly supply and make the air helps to seal oil. Plane bearing high rotational speed and needs a good cooling in the middle of the mild, all can be a large number of smooth oil spray directly to the contact surface.
