Transmission components with self-lubricating devices

Abstract

The invention discloses a transmission assembly with a self-lubricating device. The assembly comprises a long shaft, a screw cap, a plurality of rolling pieces, a fuel tank and a smearing part, wherein the long shaft is provided with a spiral rolling trough; the screw cap is provided with a perforated hole where the long shaft sleeves, the rolling trough and the perforated rolling groove form a load path, and a through hole communicating with the perforated hole is formed in the outer surface of the screw cap; the plurality of rolling pieces are accommodated in the load path; the fuel tank which is hung on the end portion of the screw cap is provided with an oil tank and a transfer piece, a part of the transfer piece is arranged in the oil tank and is defined as an oil absorption portion, and the other part of the transfer piece is arranged in the through hole in a convex manner and is defined as a connecting portion; and the smearing piece has a body and an isolating layer, wherein the connecting portion is in contact with the body and the isolating layer is in contact with the rolling trough.

Description

technical field [0001] The invention relates to a transmission assembly, in particular to a transmission assembly with a self-lubricating device. Background technique [0002] As linear transmission components are more and more widely used in modern industries, various linear transmission components have been widely used in human life, processing plants and high-tech equipment, such as: linear slide rails, ball screws, etc.; especially Generally, large and small precision machines are equipped with ball screws or linear slide rail systems of different sizes. Although the technology of linear transmission components is developing very rapidly, consumers still need to continuously improve the technology, so there are still many problems that still need to be solved. The problem of development, especially in the field of many high-precision manufacturing industrial machines that need to be more stable and quiet, there is a constant wave of R&D and improvement. Therefore, some t...

Problems solved by technology

[0004] However, after the above-mentioned conventional patents are put into practical use, because the lubricating unit and the transmission assembly use capillary phenomenon to transmit lubricating oil to the surface of the screw, when the ball screw is not installed in the equipment (such as: machine tool, robot arm, etc.) , the capillary phenomenon seems to be going on all the time, so no matter whether the ball screw is running or not, its lubricating oil will be continuously supplied to the surface of the screw (Note: If the ball screw is running, it will speed up the operation of the capillary phenomenon, and it will also make the The amount of lubricating oil flowing out is more than that when there is no operation), and the excessive concentration of lubricating oil in one place makes the lubrication uneven, and the relative waste of lubricating oil causes environmental pollution. Therefore, the conventional technology still needs to be improved.
