Jan 05, 2015· If the driven gear is larger than the driver gear, we divide the result of the ratio between the driven and driver gear into the RPM, of the driver gear. For our lager driven gear with 160 teeth, we divide the RPM of the driver gear, 100, by the result of 2 from the previous step to get 100 / 2 = 50RPM for the driven gear.

Sep 30, 2000· One thing for the service technician to keep in mind in the field is that the higher the rpm, the noisier a motor may sound to the untrained ear. It is beneficial to become aware of the different speed-related sounds motors make. Six-pole motors run at 1,200 rpm unloaded (7,200 ÷ 6) and between 1,050 and 1,175 rpm loaded. They are often used ...

Output Speed = Input Speed / Ratio of Gear Reduction. Example: A gear reducer with 1000 in/lbs of input torque, an input speed of 2000 RPM, and a reduction ratio of 3.5:1 is: Output Torque = 1000 x 3.5. Output RPM = 2000 / 3.5. Calculated out this gives an output torque of 3,500 in/lbs and an output speed of 571.4286 RPM.

By input we understand the source of power, in our case could be an electric motor. By output we mean where the power is delivered (e.g. hydraulic pump). The gear ratio i can be calculated in two ways: as a ratio between the number of teeth of the output gear and the number of teeth of the input gear [i=frac{z_{OUT}}{z_{IN}}]

Oct 16, 2019· Using the idea of gear ratios, it's easy to figure out how quickly a driven gear is rotating based on the "input" speed of the drive gear. To start, find the rotational speed of your drive gear. In most gear calculations, this is given in rotations per minute (rpm), though other units of …

Oct 19, 2005· I built a small reversing gear box for a model project using a weedwacker motor. Motor output RPM's is about 3000. Construction is simple with spur gears. Input and output shafts for gearbox are mounted onto oillite bearings. First used 90wt gear oil but found major oil leakage at bearings.

Engine RPM Calculation Basics. Engine RPM, or the speed at which the engine turns, can be calculated at any speed given the vehicle's tire size, axle ratio, and final transmission gear ratio. This calculation is used to match oversize tires with new ring and pinion gears to obtain the desired engine RPM at highway speed.

Output torque is dependent on the gear ratio used. To obtain a high output torque, a large gear ratio would be selected. Using a large gear ratio will lower the output shaft speed of the motor. Inversely, using a lower gear ratio, a smaller output torque value would be delivered into the system, with a greater motor speed at the output shaft.
