Worm Wheel Shaft: The shaft to which the worm wheel is attached, transmitting the rotational motion and torque.
Worm gear systems are typically used when the input and output shafts are non-parallel and non-intersecting, often at a 90-degree angle. They are known for their ability to provide high reduction ratios with relatively few moving parts. In some designs, the worm gear system can be self-locking, meaning the worm can turn the wheel, but the wheel cannot turn the worm, which is useful in certain applications.
