Research On Contact Stress Of The Key Components And The Distributor Machanism Of Radial Piston Pump

This subject originated from the key research project "research on electromotor and hydrostatic transmissions of industrial electrical vehicle" of Zhejiang province, we have made kinematics analysis of rollers, pistons and distributor mechanism, which are the key components of the pump. The forces acted on the parts were also analyzed. The analysis elaborates the new model radial piston pump principle, which could be serviced as guide in the project.The main work could be described as follows:1. Equation of the position, polar distance, velocity and acceleration of the position at different angular were inferred. The piston length remained outside was deduced according to the structure of the piston was calculated.2. Taking friction, stress and inertia force into consideration, the forces, pressure angular acted on the piston were entirely analyzed.3. Calculated the stress and deformation of the roller and stator by applying the method of rolling bearing. The equation of the...
