PGII-120 (Precision Planetary Gearboxes)

(1) Ratio (i=N in /N out)

(2) Backlash is measured at 2% of nominal output torque T 2N

(3) Applied to the output shaft centre at 100 RPM.

(4) These Values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) without loading at 3,000 rpm or at the nominal input speed n 1N.

(5) For continuous operation, the service lifetime is less than 10,000 hours.

(6) 3-stage is available for the following types: PGII040, PGII060, PGII080, PGIIR040, PGIIR060 and PGIIR080.

Permitted Radial And Axial Loads On Output Shaft

The permitted radial and Axial loads on the output of the gearbox depends on the design of the gearbox supporting bearings.

if Radial force F is not exerted on the centre of the output shaft X <1/2xL or X> 1/2xL, t

hen the permitted radial and axial loads can be calculated by the position load factor Kb on the above diagrams.

Permitted radial load F on the centre of the output shaft X= 1/2 X L for various output speeds.

Values provided are for 20,000 hours of life.
