Specification installed furnace capacity. 40 per furnace quench heating, avoid piling up so that the holding time is not enough defects insufficient quenching and linear plain bearings workpiece; also aging, so that the workpiece holding time fully.
Quenching, quenching Oil dispersed into the oil cooling, to prevent the workpiece too much cooling is too slow, resulting in organizational change is not fully the performance of the workpiece defects. Dispersed into the oil cooling fully, less oil into the workpiece, the oil temperature to heat up small change completely processed workpiece excellent organization. The improved process measures, linear sliding bearing parts heat treatment quality, workpiece hardness of the technical requirements of indicators, the production of stable and normal.
After the end of the installation of the linear plain bearings, in order to check the installation is correct, the operation check. Small mechanical hand rotation, to determine whether the rotation smooth.
Inspection items nick, indentation caused by dysfunctional torque instability, arising due to poor installation, mount processing bad due to the clearance is too small, installation errors, and seal friction torque and so on. If there is no exception, you can start the power operation. Power operation, start from no-load low-speed, slowly increased to the conditions stipulated in the rated operation. Test run to check the matters, whether there is abnormal sound, temperature changes of linear slide bearings, lubricant leakage or discoloration. If abnormal, should be immediately discontinued operation, check the mechanical, if necessary, to remove the bearing check.
Linear plain bearings in the assembly should have a special mold, can not be beat, when pressed into the shaft, only a small circle by the force of pressure only great circle great circle force. Assembly requires the use of pneumatic or hydraulic, pressure mounted outside the state level, if inclined to cause damage to the bearing channel due to the force up and down the touch, leaving the bearings to produce the guide ring.
Linear slide bearing life are closely related with the manufacture, assembly, use, and in every aspect of a good job, in order to make the bearing is in the best operating condition, thus extending bearing life.
