The gear wheel which engages the revolving worm. The rotating motion of the worm is transmitted through the worm gear to the drive sheave.
gear consisting of a shaft with screw thread (the worm) that meshes with a toothed wheel (the worm wheel); changes the direction of the axis of rotary motion
a device that has a spiral cut into it, attached to it is a gear that is round with teeth around the outside
a drive gear for high ratio speed reduction between non-intersecting right-angle axes
a long, thin cylinder that has one or more continuous helical teeth that mesh with a helical gear
a shaft with very coarse thread, which is designed to operate or drive another gear or a portion of a gear
a type of gear used to reduce speed or to allow torque to be transmitted between non-intersecting axles
It is a gea with one or more teeth in the form of screwed threads.
a kind of gearing which consists of a worm engaging a worm wheel, the axes of both are at right angles to each other; the worm, being restricted by fixed bearings, can only rotate without moving in an axial direction; the screw thread on the worm engages the teeth on the worm wheel and when rotated, the worm pulls or pushes the worm wheel causing rotation; used when large speed reduction ratio is desired such as in electric winches, capstans, etc.
Gear teeth spirally cut into a shaft meshing with a worm wheel; the worm gear, or worm, and the worm wheel are on perpendicular axes.
A worm gear, or worm wheel, is a type of gear that engages with a worm to greatly reduce rotational speed, or to allow higher torque to be transmitted. The image shows a section of a gear box with a bronze worm gear being driven by a worm. A worm gear is an example of a screw, one of the six simple machines.
