  1. Overbrengverhouding ( i = N in / N out ) Ratio ( i = N in / N out )
  2. Backlash is measured at 2% of Nominal output torque T2N
  3. These values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) at 3.000 rpm without load.
  4. Applied to the ourput flange center at 100 rpm.
  5. These values are measured by gearbox with ratio 10 (1-stage) or ratio 100 (2-stage) at 3,000 rpm no loading.
    By lower ratio and/or higher RPM, the noise level could be 3 to 5 dB higher.

The maximum radial and axial loads on the output shaft of the gearbox depends on the design of the gearbox supporting bearings.
Apex Dynamics uses the extension straddle oversized ball bearing design. This can take heavy load from both axles

KF radial load grafiek

 

 

 

 

 

 

 

 

 

 

Permitted radial load F2r on center of output shaft X = ½ x L for various output speeds.

KF position load grafiek

 

 

 

 

 

 

 

 

 

 

If radial force F2r is not exerted on the center of the ouput shaft X < ½ x L or X > ½ x L, the permitted radial and axial loads can be calculated by the position load factor Kb on the above diagram.
