What are the basics of worms design?

The construction of the worm-gear includes one screw device, whose teeth consist of segments of the spiral and another component that resembles a screw. The component similar to the screw is known as the worm and its fibers usually form a complete screw. This worm is usually used to drive a device that can provide a large torque. In most cases, the attempt to use the device to rotate the worm will result in the locking of the teeth. Both of these red transmission bases can be used in the tuning of the string instruments that provide torque necessary to pull the scholarly strings and then lock them in place to keep them as follows. Due to the curved nature of gears, this results in each individual tooth reminiscent of the segment cut out from the helix. The traditional Helix sets use two gears, although the design of the worms is a variant that does not. Instead, they use one spiral device and a cylinder or a rod that Mána Míní screw fiber. This worm can have a single tooth thatovrates around the perimeter only once, two teeth that span over the entire length as a normal screw or anything in between.

The main advantage of the design of the worms is that compared to other screw transfers, a large torque can be achieved. The gearbox ratios for spiral sets are usually limited to about 10: 1 and the worms sets can reach a ratio of 500: 1. Due to the nature of the worm-gear construction, each full rotation of the worm only moves the toothed to the gear, so the gear reduction is technically limited by how many teeth are driven. Powered gears with 12 teeth would result in a ratio of 12: 1, one with 120 teeth should have a ratio of 120: 1 etc.

Another basic design of the worm-gear is the way the sets tend to be self-west. Many of the worms have teeth on the gear that have a very small lead angle, what is coming close to 90 degree parallel teethAs can be found on normal sbarečky in Spar, instead of sharply the diagonal of the diagonal teeth used by the hellic wheel. If the gear has a small lead angle, then the device locks the worm instead of turning the worm. In some cases, this is a desirable result that can be used for the benefit of the device. This locking action can prevent undesirable movement of the system due to external forces on the device, such as a tensioned string or gravity.
