(1) Ratio ( i = N in / N out )
(2) Backlash is measured at 2% of Nominal output torque T2N.
(3) Applied to the output shaft center @ 100 rpm .
(4) These values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) at 3.000 rpm without load.
(5) For continuous operation, the service life is less than 10,000 hrs.

 

Permitted Radial And Axial Loads

Position-load-K-series

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.

Radial-load-K-series

Permitted radial load F2r on center of output shaft X = ½ x L for various output speeds.
Values provided are for 20.000 hours life.

(A) Ø Input shaft diameter
(B) Permitted loading values on the output shaft. Please contact Apex Dynamics for more details.
(C) For continue mode (S1), the service life is reduced to 50%.
