Analysis of driving torque on swashplate with an additional angle for aeronautical hydraulic axial piston pump

摘要

Based on the considerations of an additional angle on the swashplate, the inertia of moving slippers and pistons, the offset between cylinder barrel axis and swashplate rotating axis, the offset between piston ball center and swashplate reference plane, the driving torque model by all slippers on swashplate of the aeronautical hydraulic axial piston pump is created. The numerical calculation for a certain pump is taken as an example. From the result, ignoring inertial force can cause obvious calculation error for the torque. If the offsets are rationally designed, the slippers driving toque can rotating the swashplate to larger angle positon. If the swashplate is rotating, the rotating speed can affect the average value of the slippers driving torque.
