Just like specifying other mechanical devices, there are plenty of things involved in selecting a gear reducer for your specific application. Among the various considerations to take into account, the three most important are the torque, speed, and horsepower. It helps a lot to know what the relationship is between these elements in getting the right size and type of reducer you need.
Torque is usually considered to be the most crucial criteria when choosing a gear reducer. This is because it directly translates to the amount of work the device is needed to perform. While determining the torque can be quite straightforward in simple applications, it can be complicated in a more complex use. It involves identifying some of the phenomena that may cause motion resistance to the gear reducer. These include inertial masses, coefficients of friction, and even gravity. Considering all these elements is important to calculate the right amount of torque required.
After the power or torque has been determined, next thing to consider is the service factor to correctly size the unit you need. This element involves a number of operational parameters such as power sources, load characteristics, the number or length of work days the device will be used, and more. Typically, a gear reducer is rated for the amount of its maximum torque at a particular number of lifetime hours it is expected to be useful. This, in return, means considering the bearing life which greatly affects the life of the gearbox. It’s for this reason that such service factors have to be taken into account as well.
After all those elements are fairly calculated, the right unit and motor can now be decided upon. Getting the correct gear reducer ratio and the torque multiplication is just a matter of calculating the motor speed and the speed of the device to be driven. Finally, the right size can be determined by taking into account those different factors and their values using a standard horsepower calculation formula. The experts can help you very well on this matter to give you the best gear reduction solution.
