4 Primary Functions Of An Industrial Automation Gearbox
Hi, I’m Adam Ring with innovative IDM. People will often wonder what are the primary uses of an industrial gearbox in automation applications.
And really there’s four primary functions, first one is a speed reducer, also a torque multiplier, an inertia reducer and then a resolution increaser.
So, first of all as a speed reducer we can take a motor that might be say 1750 rpm and our application really only needs one that goes a maximum of a 175 rpm.
So, we could put a 10 to 1 gearbox on there in the output at full speed of the motor would give us a 175 rpm.
As a torque multiplier we can take whatever the normal torque of the motor is and actually multiply it by the ratio of the gearbox.
So, as another example a 10 to 1 gearbox, times say 36 inch pounds of torque and it would give us 360 inch pounds at the output of that gearbox.
As an inertia reducer we can take a really large inertia as a load and we can reduce it by the square of the ratio of the gearbox.
So, again a 10 to 1 would reduce that inertia by 1/100th so we can use a much smaller motor to control a pretty large load.
And then finally, as a resolution increaser if we had an encoder say on the back of a motor that was 2000 pulses per revolution go through that 10 to 1 gearbox and now all of a sudden we just turned that into 20,000 pulses per revolution of the output shaft.
So, these were just a few examples of how you might use a gearbox in an industrial application.
