In carving process, carpenter's cutting machine's main task is very heavy and the operation frequency is very high, so it's also one of the most simple problems. Generally speaking, the following problems can be identified as follows:
A movement, patter
The vibration and conflict of the attachment and tumbling body can happen regardless of the type of grease. It can happen more easily, and it will take more time to bear the moment, load or radial clearance.
The way to solve this problem is to advance the precision of the stick, select the bearing with small clearance or load the load on the bearing, and reduce the torque load, so as to reduce the equipment fault and the grease selected.
The motor load free operation is the same as the bee sounding, and the motor has an axially abnormal vibration, and there is a buzzing sound when opening or closing the machine.
The way of solution is that the unstable vibration occurs mostly when the motor is lubricated and the ball bearings are used at both ends of the winter, which is mainly influenced by axial vibration.
Three. The sound of impurity
It is caused by the cleanliness of the bearing or high quality, announces an irregular sound of aberration, which is sometimes no, when it is small, and occurs frequently on the high speed motor.
The solution: select good grease, advance the cleanliness, strengthen the sealing function of the bearing, and the cleanliness of the advance equipment environment
Four, Dada movement
The dynamic and static frequency changes with the bearing speed, and the surface ripple of the part is the main cause of noise.
The solution is to improve the processing quality of bearing raceway surface, reduce the amplitude of corrugation, reduce the bruise, modify the clearance and preload and cooperate, check the operation of the idle end bearing, and improve the accuracy and equipment of shaft and bearing seat.
This is the movement of a carpenter's opening machine during the processing. For these different movements, we should make the correct judgement and solve it according to the problem, and finally achieve the desired processing effect.
