3、Example of model no:

IWYHG 33A -2800 means the slewing drive has two-stage planetary gearboxes, module of first stage gearbox is 3mm, module of second stage gearbox is 3mm, the design mark is A, and the nominal output torque is 2800N.m.

4. Definition

1) Total displacement(ml/r) is the amount of oil needed for one rotation of hydraulic transmission drive.

Total displacement (ml/r) =displacement of hydraulic motor (ml/r) * reduction ratio

2) Theoretical oil flow of the pump (1/min)= total displacement (ml/r) * output shaft speed of hydraulic transmission drive (r/min) / 1000
