Any instrument will have various problems after being used for a certain period of time. This is normal. For the ball screw used in production, there will often be some small faults. If we want to keep the ball screw in good condition, then we need to be in time. Clear, let's talk about the inspection and maintenance knowledge of the ball screw, let's take a look!
When using a ball screw, if the measured screw's dial indicator does not swing from side to side when it is in use, it means that the screw is in good position and there is no cross movement. If the indicator of the dial indicator In a state of constantly swinging, it means that the lead screw has moved. For a dial indicator, the difference between the largest measurement value and the smallest measurement value is the lead screw.
How to detect the problems between the ball screw support systems, when we use the machine tool, there will be a relatively large reverse error, and then the positioning accuracy tends to be unstable, and the other is when it is used beyond the quadrant. When there is a knife mark, you must check the clearance of the lead screw system at this time. In other words, the problems that arise are directly related to the clearance of the lead screw.
If there is no problem with the bearing, then we will do the pre-addition again. If there is a problem with the bearing, it should be repaired when it is time to repair, and replaced when it is time to replace it. For the above problems, when inspecting the ball screw, we first look at whether the back cap of the support bearing is in a locked state, and then check the wear of the support bearing, or it may be the presence of preloaded bearing pads. The problem of use.
