Worm processing mechanism capable of automatically radiating heat

Abstract

The invention discloses a worm processing mechanism capable of automatically radiating heat. The worm processing mechanism is used for processing a blank (1) into a worm. The worm processing mechanism comprises a blank bearing member (2), a sleeve (3) with an external thread, a drive sleeve (4) with an internal thread, and a rack (7), wherein the blank bearing member (2) is used for bearing the blank (1), the upper end and the lower end of the blank bearing member (2) are respectively fixedly arranged in the sleeve (3) with the external thread by means of an upper bearing (21) and a lower bearing (22) relative to the sleeve (3) with the external thread, the sleeve (3) with the external thread is in thread fit in the drive sleeve (4) with the internal thread, the lower end of the drive sleeve (4) with the internal thread can be rotatably arranged on the rack (7) by means of a thrust bearing (47), a cavity (72) is arranged inside the rack (7), and in the cavity (72), a drive motor (8) is fixedly arranged on the left-inner side wall of the cavity of the rack (7).

Description

technical field [0001] The present application relates to the field of worm machining, in particular to a worm machining mechanism capable of automatically dissipating heat. 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...

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
