Application of hydraulic motor with planetary gear train

1. Motion synthesis Synthesis of the movement is to output the two input motion into a movement. Differential gear system of degrees of freedom is equal to 2, when given any two components determine movement, another component of the movement can be determined. Using a differential gear system's characteristics can be realized by synthesis. 2. compact power transmission Planetary gear system can simultaneously by several uniform distribution of planetary gear transmission of motion and power (see left-hand chart). Arising from these planets orbit the centrifugal force and profile between the reactions of the radial component can be balanced each other, so the spindle bearing small, passing power. Because it uses internal gear, full use of drive space, and the input and output shaft in a straight line.
