Customized AISI 4140 Steel Transmission Parts Worm Gear Shaft Pair Set
Worm gear is usually meshed with a spur gear or a helical gear, which is called the gear, wheel, or worm wheel.
Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio.
For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1.
