Does a Small Gear Driving a Large Gear Speed Up or Slow Down?
1 Answers
Small gear driving a large gear slows down. When a small gear drives a large gear, the rotation speed decreases. This is based on the principle of gear ratio. When two gears with different diameters mesh together and rotate, the larger-diameter gear naturally turns slower than the smaller-diameter gear. Their speed ratio is inversely proportional to the size of the gear diameters. Below are the specific functions of gear meshing: Changing speed or torque: There are many gears inside the transmission and drivetrain. The gears in the transmission serve to change speed and torque. The differential contains a main reduction gear, whose function is to reduce speed and increase torque. Power transmission: Gears have a power transmission function. Many four-wheel-drive vehicles have numerous gears in the transfer case, which serve to transmit power. The main reduction gear in the differential also has a power transmission function. Many gears transmit power by meshing with each other. Gears in the steering system also serve to transmit power. Achieving gear ratios: By combining different gears, the transmission achieves various gear ratios, allowing the vehicle to adapt to different driving conditions.
