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

Abstract

A worm machining mechanism is used for machining a blank (1) into a worm; the machining mechanism comprises a blank carrier (2), a sleeve (3) with external threads, a driving sleeve (4) with internal threads and a rack (7); the blank carrier (2) is used for carrying the blank (1); the upper end and the lower end of the blank carrier (2) are axially fixedly mounted in the sleeve (3) with the external threads relative to the sleeve (3) with the external threads by an upper bearing (21) and a lower bearing (22); the sleeve (3) with the external threads is in threaded fit in the driving sleeve (4) with the internal threads; the lower end of the driving sleeve (4) with the internal threads is rotatably arranged on the rack (7) by a thrust bearing (47); a chamber (72) is arranged in the rack (7).

Description

technical field [0001] The present application relates to the field of worm machining, specifically a worm machining structure. 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-stage transmission, so the worm t...
