Applications

 power tool, industrial machinery


Internal spur gears come in a ring structure with straight teeth created on the inner diameter of it. (See the image on the left) This type of gear is common in the transmission system of a car, a motorcycle, or most motor vehicles. For example, the internal spur gear is a necessary part of a planetary gearbox where multiple spur gears work within the internal ring gear. When operating, the internal gear itself does not rotate. Instead, the gears within the ring revolve around a drive shaft to transmit torque. Besides vehicles, the internal spur gear is also used in industrial machinery and some power tools.
