Gear reducers are required for high-efficiency machinery that operates at high speeds. The speed produced by the machinery must be adjustable to fit the required speed. A gear reducer comprises a large gear positioned next to a smaller gear, and both turn together.
When a large gear is coupled with a smaller gear in a single reducer system, the smaller gear produces twice as many revolutions for every singular turn of the larger gear. Speed increases as torque decreases with the repeated spins of the smaller gear.
The gear reduction process takes place at specified ratios of the driver and driven gear. The energy shift is achieved by changing the ratio of the moving gears in a gear reducer.
