What are the common faults of the horizontal axis of drilling and milling machines?
The horizontal axis is an important component of the drilling and milling machine equipment. It is one of the indispensable components in the operation of the drilling and milling machine. In actual use, the horizontal axis is also a component that is prone to failure. Then, if the horizontal axis of the drilling and milling machine fails, what should How to deal with it?
1. The horizontal shaft bearing of the drilling and milling machine is damaged. Failure to lubricate properly can easily lead to damage to the horizontal shaft bearings of the drilling and milling machine. This rarely happens, as long as you add lubricant on time. If the horizontal shaft bearing is damaged, it will be troublesome. It needs to be disassembled at this time. First remove the bearing gland to see which bearing is broken, and then replace it after confirming it.
2. Oil leakage due to wear: The motor drive shaft under the horizontal shaft is sealed by an O-ring and closed by a bearing sleeve. Due to long-term use, the O-ring is worn and the horizontal shaft passes It runs at high speed, so the lubricating oil flows out from here. Solution: First take out the pulley, then remove the bearing sleeve, and then replace it with an O-ring.
3. There is a gap due to large runout of the horizontal axis: First, after the horizontal axis of the drilling and milling machine has been used for a period of time, there may be some gap due to the bearing. Solution: There is an adjusting nut behind the horizontal axis of the drilling and milling machine. Tighten the flower nut inward, usually 3 buckles is enough. First loosen the outer flower nut, then tighten the inner one, and finally tighten it. That outside lock.
