Gear Ratio Calculators motor driven systems usually have optimal motor speeds at which the motor operates with the greatest power and efficiency. These motor speeds are expressed in rotations per minute (RPM) of the motor shaft. In many applications, this optimal motor speed is not the optimal speed (RPM) at which the load should be driven. Gearing is used in the form of differently sized gears. These gears are attached to the motor shaft and load shaft, and are coupled together by intermeshing teeth. This produces a gear ratio, which is a direct measure of the ratio of motor shaft rotational speed to load shaft rotational speed. Use these tips to learn how to determine gear ratio. Here's Tips On How to Determine Gear Ratio Calculators :
- Determine the number of gears in the gear train. There must be at least 2: a drive gear attached to the motor shaft and a driven gear attached to the load shaft. There may be any number of gears successively connected to transmit power from the drive gear to the driven gear. These are called differential gear ratio. They are use to share the work of generating the desired gear ratio when direct gearing between the drive gear and the driven gear would make 1 or both of those gears unwieldy or not readily available.
- Note the number of teeth on each gear used in the system. Gear ratio is determined starting with the drive gear, so it should be noted which gear in the gear train, counting from the drive gear to the driven gear, has what number of teeth.
- The drive gear for gear ratio calculators and the first gear to which it meshes. The gear ratio is simply the number of teeth on the meshed gear divided by the number of teeth on the drive gear with which it meshes.
- Determine the gear ratio for the next gear in the gear train. If there is only 1 driver gear and 1 load gear, the calculation is complete. If there are idler gears in the gear train, proceed with the calculation. Divide the number of teeth on the meshed gear by the number of teeth on the gear with which it meshes.
- Determine the intermediate gear ratio formula. Figure for each idler gear in the system, starting from the drive gear and working toward the load gear. Treat the preceding gear, which could be the drive gear or the preceding idler gear in the train, as if it were the drive gear as far as this next gear is concerned. Divide the number of teeth on the meshed gear by the number of teeth on the gear it meshes with to calculate the intermediate gear ratios.
- Finish the overall gear ratio calculation. When you have each pair of gear ratios determined, there should be 1 less ratio than the number of gears in the train. Multiply all of these ratios together. The result is the overall gear ratio.
- The POWER needed just like xbox 360 laptop to drive the load is geared up or down from the motor by transmission gear ratios. The motor must be sized to provide the power needed by the load after the gear ratio is taken in to consideration. A geared up system (where load RPM is greater than motor RPM) will require a motor that delivers optimal power at lower rotational speeds. A geared down system (where load RPM is less than motor RPM) will require a motor that delivers optimal power at higher rotational speeds.
