Description
Technical Field
The invention belongs to the technical field of equipment maintenance, and particularly relates to a replacement device for a damaged end cover of a ball screw nut.
Background
A ball screw is a mechanical structure that converts rotational motion into linear motion, and is widely used in various industrial devices and precision instruments. When the transmission device works, the ball rolls in the nut in an infinite circular rolling motion, so that higher transmission efficiency is obtained.
The ball circulation mode that present ball screw is commonly used is two kinds for the inner loop and extrinsic cycle, either, all need carry out certain sealed by the end cover to the nut to prevent that the ball from droing in the circulation process. However, in use, for various reasons, there are times when the end cap is damaged or falls off, in which case the balls may unscrew off the open end of the nut and no longer circulate effectively within the nut, causing the screw to fail. In repairing such a failure, there are several approaches for different types of nuts:
(1) the screw rod sleeve or the nut sleeve is integrally replaced.
(2) And replacing the nut end cover.
(3) And resetting and installing the original end cover.
The first method is the most thorough maintenance, but the whole screw rod needs to be disassembled and assembled again, so that the time consumption is longest, the cost of spare parts is highest, and the purchasing time of the spare parts is uncontrollable. Compared with the first method, the second method only reduces the cost of spare parts, but the operation can be carried out only after the nut is replaced by disassembling at least one end of the screw rod and removing the bearing at one end of the screw rod, the screw rod also needs to be debugged again, and the bearing is in danger of causing certain damage to the screw rod when being disassembled and assembled every time. If the third method can be realized most simply and quickly, but the end cover which is usually dropped off cannot be effectively fixed by the original fixing mode, the damaged end cover cannot be used continuously, and the function of blocking the ball from dropping off is lost, so that the method cannot be realized in most of the time.
