Abstract

The invention relates to a self-lubrication module of outside loop ball screw and comprises the oil box and material containing the oil. Its features lie in: the self-lubrication module is set on the drainback system of the ball screw and introduces the lubricating oil into the drainback system through the material containing the oil to lubricate the ball directly, so the self-lubrication module has the functions of storing the lubricating oil and saving the space, guarantees the effective stroke of the ball screw, does not waste the lubricating oil by means of directly lubricating the ball, extends the useful life of the outside loop ball screw and increases the partition cycle of adding the lubricating oil.

Description

technical field

[0001] The invention relates to an external circulation ball screw self-lubricating module, which is used for lubricating the external circulation ball screw. Background technique

[0002] The ball screw is a work piece that operates the machine by the relative movement of the nut and the screw. The movement of the nut is based on the rolling of the steel ball between the teeth of the nut and the screw to generate relative movement. Therefore, the ball screw has a relatively Excellent mechanical 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. The lubrication system of the traditional ball screw can be divided into two types: the first one is as Figure 7 and Figure 8 As shown, the lubricating system 60 is hung on both ends of the nut 10, the lubricating oil is stored in the lubricating system 60, and then the oil...
