Problems solved by technology

[0004] 1. These two lubrication 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.
[0005] 2. These two designs directly lubricate the thread surface of the screw, and the ball can only be lubricated when the ball moves to the surface of the thread stained with lubricating oil. Therefore, it is still an indirect method of lubricating the ball and requires more lubricating oil In order to effectively lubricate the ball, it is easy to cause waste of lubricating oil and uneven lubrication

Embodiment 1

[0035] figure 1 It is the upper view of the nut of the exceptional circulation ball screw in this embodiment; wherein the self-lubricating module 20 of the present invention is arranged on the return system of the outer diameter of the nut 10, and the self-lubricating module 20 is provided with a bolt hole for installing the bolt 30, and The nut 10 is provided with matching screw holes, and the self-lubricating module 20 is fixed on the nut 10 by means of bolts 30 . figure 2 It is a three-dimensional schematic diagram of the self-lubricating module of this embodiment; the self-lubricating module 20 is mainly composed of an oil storage box 21 and an oil-containing material 23. The space in the oil storage box 21 is used to store lubricating oil, and there is a The bolt hole 211 that allows the bolt 30 to pass through and the groove 212 in the shape of the return system (not shown) that fits the nut. At the same time, there are holes in the groove 212 so that the oil-containin...

Embodiment 2

[0039] image 3 It is a three-dimensional exploded view of the self-lubricating module of this embodiment; the oil storage space of the self-lubricating module 20 is designed to be composed of two components, that is, the oil storage box is composed of an upper cover 25 and a lower cover 22, And an oil-containing material 23 is set in the oil storage space; a countersunk bolt hole 251 is provided in the upper cover 25 to provide a bolt (not shown) to pass through and screw lock, and an oil injection hole 252 is used to lubricate the self-lubricating module 20 Supplement; the outer side of the lower cover 22 is provided with a groove 221 and a bolt hole 222 matching the shape of the external circulation return system (not shown), and a lubrication hole 223 is pierced on the groove 221; the shape of the oil-containing material 23 conforms to the shape of the lower cover 22 The shape of the inner side of the lower cover 22 is placed on the inner side of the lower cover 22.

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...
