WebNov 3, 2024 · 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. WebUnlike a spur gear, the normal force on the teeth is not at a 90 degree angle from the gear shaft. The diagram below shows the normal force on the driver teeth. We can decompose the normal force into tangential, radial, and axial components. Notation for force diagram:
