Abstract

The invention relates to a worm rod processing mechanism with a driving motor separation baffle plate (111). The worm rod processing mechanism is used for processing a blank (1) into a worm rod, and comprises a blank carrying element (2), a sleeve (3) with external screw threads, a driving sleeve (4) with internal screw threads and a machine frame (7), wherein the blank carrying element (2) is used for carrying the blank (1), the upper end and the lower end of the blank carrying element (2) are respectively and fixedly arranged in the sleeve (3) with the external screw threads through an upper bearing (21) and a lower bearing (22) in a direction opposite to the axial direction of the sleeve (3) with the external screw threads, the sleeve (3) with the external screw threads is matched in the driving sleeve (4) with the internal screw threads through screw threads, and the lower end of the driving sleeve (4) with the internal screw threads is rotatablely arranged on the machine frame (7) through a thrust bearing (47).

Description

technical field

[0001] The present application relates to the field of worm machining, in particular to a worm machining mechanism with a drive motor baffle. 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-sta...
