A Worm Machining Mechanism with a Lubricating Oil Supply System

Abstract

The invention discloses a worm processing mechanism with a lubricating-oil supplying system. The worm processing mechanism is used for processing a blank piece (1) into a worm and comprises a blank-piece bearing piece (2), a sleeve (3) with external threads, a driving sleeve (4) with internal threads and a rack (7), wherein the blank-piece bearing piece (2) is used for bearing the blank piece (1); relative to the sleeve (3) with the external threads, the upper end and the lower end of the blank-piece bearing piece (2) are respectively and fixedly arranged in the sleeve (3) with the external threads by an upper bearing (21) and a lower bearing (22) in an axial manner; the sleeve (3) with the external threads is matched in the driving sleeve (4) with the internal threads by threads; the lower end of the driving sleeve (4) with the internal threads can be rotatably arranged on the rack (7) by a thrust bearing (47).

Description

technical field [0001] The application relates to the field of worm machining, in particular to a worm machining mechanism with a lubricating oil supply system. Background technique [0002] The worm drive is composed of a worm and a worm gear, and the worm is generally the active part. Worms, like threads, can be divided into right-handed and left-handed. Worm drive has the following advantages: 1. Large transmission ratio and compact structure. The number of worm heads is represented by Z1 (generally Z1=1~4), and the number of worm gear teeth is represented by Z2. It can be seen from the transmission ratio formula I=Z2 / Z1 that when Z1=1, that is, the worm is single-headed, and the worm must turn Z2 to turn the worm wheel for one turn, so a large transmission ratio can be obtained. Generally, in power transmission, take The transmission ratio I=10-80; in the indexing mechanism, I can reach 1000. Such a large transmission, such as gear transmission, needs to adopt multi-...

Problems solved by technology

4. The efficiency of worm transmission is low. It is generally believed that the efficiency of worm transmission is lower than that of gear transmission.

However, the shape processing and manufacturing of the worm gear tooth profile is troublesome, and it is difficult to ensure the accuracy of the processed tooth groove shape and position

[0003] In particular, in some specific application areas, such as soft materials (such as plastics) processing, traditional metal processing methods will be difficult to meet the requirements of reducing costs and improving processing speed and accuracy
