If the thrust pad wears and the motor swing are small, the thrust tile and the anti-heavy bolt, the thrust head mirror plate bolt and the insulating pad can be kept unchanged, and the proper treatment can greatly reduce the workload of maintenance and ensure the quality of maintenance. . However, if the thrust tile wears a lot, it must be ground. After grinding, the motor should be adjusted according to the level before the inspection. If the deviation of the motor swing is too large, the swing of the motor should be adjusted, but the direction of the swing should be Before adjustment, the adjustment value should be close to the adjustment. Other key data should be compared before and after disassembly and assembly. The original measurement data should also be used for adjustment. However, the gap of the upper guide bush should be determined according to the actual swing of the upper guide.
Since the motor lower guide of the unit is a roller bearing, the machining accuracy of the shaft socket is high, and the position of the shaft is easy to determine. For the lower guide bush of the motor, the machining surface and the thrust head journal of the upper and lower cylinders can be used. The distance between the motor shaft journal and the gap between the upper and lower guide bushes are used as the reference, and the position of the shaft is determined after comprehensive analysis.
Precision alloy, is a kind of alloy owning special physical properties (such as magnetism, electrical, thermal and other properties).The vast majority of precision alloy is black metal based, only a few is based of nonferrous metals. It usually includes magnetic alloys, elastic alloys, expansion alloys, thermal bimetal, electrical alloy, hydrogen storage alloys, shape memory alloy, magnetostrictive alloy and etc.
In addition, in practical application some new type alloy are also considered to belonging into precision alloy, such as vibration damping alloy, stealth alloy, magnetic recording, superconducting alloys and microcrystalline amorphous alloy and etc.
