Sliding bearing fracture failure prevention measures

1. Every 40 root quenching furnace heating, avoid heating and linear sliding bearing quenching piled up the defect of heat preservation time is not enough; So when aging, make the workpiece heat preservation time fully. 2. Quenching, quenching oil processing with disperse into the oil, prevent the workpiece cooling too slow, too many organization transformation of inadequate performance of components caused by defects. Disperse into oil cooling, due to fewer artifacts into the oil, the oil temperature rising, organization change completely, after processing the workpiece excellent performance. With the improved process measures, the linear sliding bearing parts heat treatment quality is good, the workpiece hardness meet technical requirements, production stability is normal. Linear sliding bearings after installation, in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, the change of linear sliding bearing temperature, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Linear sliding bearings in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle. Require the use of pneumatic or hydraulic assembly, touched up and down when pressed to outside the state level, such as with sloping channel by mechanical damage can lead to bearing, guide ring and the bearing. Linear sliding bearing life is closely related to manufacturing, assembly, use, and must be made at each link to make the bearing is in optimum operation state, so as to prolong the service life of bearing.
