Radial piston hydraulic motor | Hägglunds CBp 5/64 axial and radial bearing 4. Cylinder block, spline Cylindrical roller bearing 7. Connection housing 8. Distributor 9. Wear ring 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 in the system. Oil main lines are connected to ports...
