BS-40 Worm Wheel
A worm wheel is a type of gear used in mechanical engineering. It is a cylindrical gear with helical teeth cut into its circumference, which mesh with the teeth of a worm gear. The worm wheel is usually mounted on a shaft, and its teeth are usually arranged at right angles to the worm gear's teeth. The worm wheel is typically used to transmit rotation from the worm gear to another gear or a shaft.
