Worms are extensively utilized daily and are crucial in advancing contemporary industry. Owing to the unique characteristics of worm gear transmission, the material used for the worm must possess adequate strength and excellent properties such as anti-friction, wear resistance, and anti-sticking functions. Bronze is a commonly chosen material for the worm gear ring, typically paired with a steel worm that has been hardened and ground. In terms of materials, carbon steel and alloy steel are frequently employed for making worms, and for high-precision applications, precise grinding is necessary. The term "worm transmission" denotes the process of automatic delayed transmission via the worm mechanism. In cases where self-locking is absent during reverse motion, the worm can function as an automatic accelerator transmission mechanism.
The worm exhibits vital characteristics: it is inherently self-locking, featuring a minimal helix angle and the sole ability to drive the worm wheel transmission. Conversely, the worm wheel cannot drive the worm's rolling motion. This distinction arises because the worm wheel's teeth are designed as continuous and uninterrupted spiral teeth, ensuring a seamless meshing process with the worm teeth. As a result, there is a lack of specific entering and exiting phases during the meshing interaction, contributing to a smooth and noiseless transmission operation during functionality.
