RPM’s of motor X Tire Radius (in inches) / Gear Ratio X 168 = Miles per Hour Example: A golf car with 3000 RPM motor with an 8" tire and a 12.44:1 gear ratio (a standard in golf cars): 3000 X 8 / 12.44 X 168 = 11.48 mph (standard speed for golf cars) • with 10" tires, top speed is 14.35 mph Use this calculator to determine your gear ratio and vehicle’s speed in any gear and any engine RPM for best performance. Scroll through the list of popular transmissions to find yours. Or, change input variables (engine RPM, axle gear ratio and tire height) to determine vehicle speed in each forward gear. If we have 1:1 gear ratio, speed and torque remain the same, just as if we used idler gears. We can already calculate gear ratios of two meshed gears, but what if there are more gears in the mechanism? In this case, we ignore all the idler gears and calculate ratios for all pairs of driver/follower gears. DIY Planetary Gearbox for Nema17 Stepper Motor: I wanted to build a small and light gearbox for a stepper motor (used as excuse: for building a light extruder for a 3D printer - didn't trust the bowden setup, and the scavenged driver might not have enough torque for a direct drive - real cause:... *Professor Motor is proud to offer the following technical information for chassis tuning. Lower gear ratios (higher ratio numbers) give your car faster acceleration out of a corner, higher gear ratios (lower ratio numbers) gives your car faster top speed. Gear Ratio Effective Change Chart. Another helpful tool for deciding on a new gear ratio is this gear ratio effective difference chart. Start by finding your current gear ratio along the top row and then work your way down the column to find the effective difference of other gear ratios. Torque Calculations for Gearmotor Applications Given a lever, Archimedes may have been able to move the Earth, but given one of our DC motors just what can you lift? Torque is a force around a given point, applied at some distance from that point.

Considering making modifications to your Jeep? Whether it is changing an axle or going with different tires this chart is helpful in finding the right Tire Size to Gear Ratio that you need to achieve the optimal performance for your particular application. Most industrial gear motors are AC-powered, fixed-speed devices, although there are fixed-gear-ratio, variable-speed motors that provide a greater degree of control. DC gear motors are used primarily in automotive applications such as power winches on trucks, windshield wiper motors and power seat or power window motors. The mounting offering includes solid and hollow shafts. They are energy efficient and usually chosen when demand for drives with angular geared motors. Due to worm gear stage, high ratios can be implemented. SIMOGEAR helical worm geared motors represent the cost-effective solution for angular geared motors in the lower torque range.
