Problems solved by technology

[0005] 1. Both of these two lubricating systems will lengthen the nut and shorten the original effective stroke of the ball screw. Therefore, it is necessary to change other mechanisms to increase the length of the thread to maintain the original effective stroke.
[0006] 2. These two designs directly lubricate the thread surface

Abstract

The present invention provides an end plugged ball screw rod with lubricating mechanism. The lubricating mechanism consists of mainly oil storing chamber, oil bearing material and auxiliary block, and features that the lubricating mechanism is set inside the screw nut of ball screw rod and the oil bearing material inside the oil storing chamber leads the lubricating oil to between the reflux device and the reflux porous channel to lubricate balls directly without increasing the length of the screw nut additionally. The lubricating mechanism of the present invention can store lubricating oil, save space, and lubricate end plugged ball screw rod effectively.

Description

technical field [0001] The invention relates to an end-plug type ball screw with lubricating mechanism, which is used for lubricating the end-plug type ball screw. Background technique [0002] The ball screw is a mechanical work piece that moves relative to the nut and the screw. The movement of the nut is caused by the rolling of the steel balls between the threads of the nut and the screw. Therefore, the ball screw has better mechanical properties. transmission efficiency. However, if the ball screw lacks lubrication for a long time, the friction between the nut and the screw may increase and the wear of the ball screw may be accelerated. [0003] There are roughly two types of lubrication systems for traditional ball screws: the first one is as Figure 8 and Figure 9 As shown, the lubricating system 80 is hung on both ends of the nut 10, the lubricating oil is stored in the lubricating system 80, and then the oil absorbent 81 is directly applied to the surface of the ...
