Detailed explanation of the transmission principle of worm gear reducer 2023-08-02
Worm drive: Worm drive is a transmission that transmits motion and power between two axes that are interlaced in space. The angle between the two axes can be any value, and the commonly used one is 90°.Worm drives are used to transmit motion and power between staggered shafts.1. Introduction The worm drive is composed of a worm and a worm wheel, and generally the worm is the active part.Worms, like threads, can be divided into right-handed and left-handed worm drives, which are called right-handed and left-handed worms, respectively.The worm with only one helix is called a single-head worm, that is, the worm rotates once, and the turbine turns one tooth. If there are two helixes on the worm, it is called a double-head worm, that is, the worm rotates once, and the turbine turns two teeth. .2. Features (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 to make one turn, so a large transmission ratio can be obtained.
