Hägglunds Quantum | Radial piston hydraulic motor Functional description Shaft side Fig. 1: Section view of radial piston hydraulic motor QMX 8. Cylindrical roller bearing 5. Cylinder block, hollow radial bearing 6. Cylinder block, spline When the hydraulic pressure is acting on the pistons, the cam rollers are pushed against the slope on the cam ring that is rigidly connected to the housing, thereby producing a torque. The cam rollers transfer the reaction force to the pistons which are guided in the cylinder block. Rotation therefore occurs, and the torque available is proportional to the pressure...
