A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear .
What Is a Worm Gear? A worm gear is a gear consisting of a shaft with a spiral thread that engages with and drives a toothed wheel. Worm gears are an old style of gear, and a version of one of the six simple machines. Basically, a worm gear is a screw butted up against what looks like a standard spur gear with slightly angled and curved teeth.
Aug 15, 2018 · Operating principle. A special design of the gear wheel is the so-called worm. In this case, the tooth winds around the worm shaft like the thread of a screw. The mating gear to the worm is the worm gear. Such a gearbox, consisting of worm and worm wheel, is generally referred to as a worm drive. Animation: Worm drive.
Nov 6, 2023 · Worm gears are power-transmission components primarily used as high-ratio reductions to change the direction of shaft rotation and to decrease speed and increase torque between non-parallel rotating shafts. They are used on shafts with non-intersecting, perpendicular axes.
Worms and worm gears are gear sets that offer high gear reduction and torque multiplication with a small footprint. A worm drive is a cylindrical gear with a shallow spiral thread that engages the worm gear in a non-intersecting, perpendicular axes configuration.
Worm gears are constructed of a worm and a gear (sometimes referred to as a worm wheel), with non-parallel, non-intersecting shafts oriented 90 degrees to each other. The worm is analogous to a screw with a V-type thread, and the gear is analogous to a spur gear.
A worm gear is a staggered shaft gear that creates motion between shafts using threads that are cut into a cylindrical bar to provide speed reduction. The combination of a worm wheel and worm are the components of a worm gear. Speed reduction is determined by the number of worm threads and the number of teeth on the worm wheel.
Jan 15, 2024 · A worm gear is a type of cylindrical gear on which the teeth are helicoid — it has teeth that are cut at an angle to the axis of rotation. They are similar to helical gears but offer advantages both in torque capacity and smoothness of operations. Worm gears are part of a set of gearing components and require a mating worm in order to function.
Dec 23, 2020 · In this video we first hand draw a basic worm gear meshed with a worm wheel. Then we take a look at the function of a worm gear assembly and how to find the...
Jul 21, 2022 · A worm gearbox is a type of gearbox that uses a combination of shafts, worm gears, bearings and toothed wheels to produce movement. They can be used to drive a number of mechanical systems and also used in some engines.
