FAQs

Gearboxes

What is a servo gearbox?

A servo gearbox, is a high precision gearbox typically used between the servo motor and the driven mechanism in a motion control application. It serves two purposes:

  1. Allows the motor to run in the optimal speed and torque range while producing the desired speed at the driven mechanism.
  2. Reduces the inertia mismatch between the driven mechanism and the servo motor by the square of the ratio. For example, if the mismatch of the inertia is 100:1, a gearbox with a 10:1 ratio reduces this to 1:1 (mismatch divided by ratio squared)

What is a speed reducer gearbox? 

A speed reducer gearbox, or gear reducer, is a mechanical device that uses a system of gears of different sizes and tooth counts to decrease the output speed of a motor while increasing the torque. The arrangement of the gears generally results in the speed at the output of the gearbox being less than the input of the gearbox (motor speed), though there are gearboxes designed specifically to increase speed.

Using a speed reducer gearbox allows a smaller motor to be used while still providing the desired torque for the driven system.

Servo Couplings

Can keyways be machined into GAM couplings?

Keyways are not recommended by GAM as they can actually introduce backlash into machine systems overtime.  While not recommended, keys can still be machined into the couplings upon request. Read more about coupling keyways >

What is the standard bore tolerance for GAM couplings?

The standard bore tolerance provided on GAM couplings is G6. The shaft and coupling hub should be designed for a transition fit (Example: A coupling with a bore diameter of 28mm G6, should have a mating shaft tolerance of 28mm k6).

Can you adjust the disengagement torque on safety couplings?

Yes. We typically like to set the disengagement torque on all of our safety couplings before we ship them out, but they can also be adjusted in the field. Here's how to adjust disengagement torque >

 

Linear Mount Kits

How do I quickly size an LSK (Linear Slide Kit)?

The main considerations for sizing an LSK are the motor or gearbox shaft diameter, the linear slide shaft diameter, and the torque requirements of the application.
