# Gear reduction ratio

While the transmission offers changeable gear reduction, the primary and secondary gear reduction remains set during operation. With this design a common and easy place to make a gear reduction change on a V-twin is at the rear wheel. However, with secondary belt drives, due to the lack of different size pulleys, gearing options can be limited. How does a Gear Reducer Works While gearbox reduction and worm gear reducer are extremely common in mechanical power transmission equipment, many would be unable to describe how it works. The following is a basic explanation of how gearbox reduction works, along with mathematically-based description of its function.

Based on the model, the optimal fixed gear ratio is 8:1. The measured acceleration time for a Baja Car with a 3.5:0.9 CVT ratio and 8:1 fixed gear ratio was 6.0 ± 0.27 s, which agrees with the 5.8 s predicted by the model. Gear ratios and compound gear ratios Working out simple gear ratios (two gears) A feature often requested in my gear program is that it should calculate and display the gear ratio. The reason it does not have this feature is that the gear ratio is also the tooth count ratio (of the two gears), and that is a value that the user has to enter. Gearbox reduction is based on the mathematics of gear ratios. A system that uses gear ratios pairs different sizes of wheels, belts, or chains and sprockets to shift motor output. At their most basic, all of these parts are circles. Digging back into our grade school geometry lessons, we remember that circles contain different measurements.

Both Gear Ratio and Gear Reduction are mathematical expressions that describe the relationship between a Driving Gear and a Driven Gear. However, It's important to understand the different, but similar ways they are expressed. Both use the number of teeth on each gear as key values, although their order is reversed. Lets say we have 2 gears. Our input gear (attached to our motor) has 10 teeth Our output gear has 50 teeth Our Gear ratio is 5:1 Motor Torque x gear ratio = torque at the wheel 5oz x 5:1 = 25 oz What if our gear ratio were 1:3 ? 5oz x 1:3 = 1.6oz The “reduction” or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5). The input gear in this gear train has 13 teeth and the idler gear has 21 teeth. Considering only these gears, the gear ratio between the idler and the input gear can be calculated as if the idler gear was the output gear. Therefore, the gear ratio is driven/driver = 21/13 = ~1.62 or 1.62:1.
