straight line gear called "rack" on which a small rotary gear called "pinion" moves. According to teeth position: Gears are classified as straight, inclined and curved. 1. Straight gear teeth are those where the teeth axis is parallel to the shaft axis. 2. Inclined gear teeth are those where the teeth axis is at some angle. 3.

The worm drive. A better solution to meeting a requirement for compactness or light weight would be the worm drive. The worm drive has two parts – the worm gear, a screw-shaped component with a spiral thread at the top of the drive, driving a worm wheel, which looks similar to a spur gear, at 90 degrees to the axis of rotation of the worm gear.

This is a schematic of an automotive differential. Notice that this is a planetary gear train. Assume that the engine is being driven at 2000 rpm, the transmission is in 4th gear (direct drive, 1:1 ratio) to the driveshaft. Gears 4,5,6,7 = 15 teeth, Gear 3 = 43 teeth, Gear2 = 12 teeth, rear wheels = 40.64 cm.

Thinking of gears as levers shows exactly how they work. Suppose you turn the axle at point (1). The bar connecting points (1) and (2) moves faster and with less force at point (2) because it's working as a lever. If you can't see this, suppose the red bar were a spanner and you pushed at point (2) to undo a nut at point (1) in the center.
