WebTwo straight-toothed bevel gears mesh with a shaft angle of 90° and a diametral pitch of 5. The pinion has 20 teeth, and the gear ratio is 2:1. The addendum and dedendum are the same as for 20 stub teeth. For the gear, determine the pitch radius, cone angle, outside diameter, cone distance, and face width. WebTo determine your gear ratio, you divide the spur gear tooth count by the pinion gear tooth count: Spur Gear / Pinion Gear = Gear Ratio 86 / 23 = 3.74:1 (This means the spur gear will rotate once for every 3.74 times the pinion gear, and therefore the motor shaft, does.)

WebThe Power Transmission often includes a Gear Ratio or Mechanical Advantage. A Gear Ratio can increase the output torque or output speed of a mechanism, but not both. A classical example is the gears on a bicycle. ... where nrev in is the number of revolutions of the input gear: number of teeth that mesh = nrev in 2 π r in / Pd. Web11.12:1.
