KYB Hydrostar Motor(KYB HYDROSTAR MOTOR)

Features

  • Rigid structure and reliable design. Suitable for all uses with providing satisfying life and performance.
  • Large-capacity shaft bearing permits large transverse load.
  • Smooth in all the range of rotating speed with providing high torque.
  • Wide variety of shafts and port forms.
  • Since three drain ports are arranged, the mounting position can be freely selected.
  • Wide variety of hydraulic seals.


Structure

The hydraulic energy acted on pistons in the cylinders that are arranged radially around the output axis is transmitted to the eccentric cam which is integral construction with the axis through the connecting rod to rotate the output axis. The valve at the back of the motor rotates in synchronization with the output axis and it distributes oil to each cylinder properly. The two-speed wheel motor in the above picture has the structure that the volume of the motor is to be changed by the change of the eccentricity of the cam with the piston in the eccentric cam.



Example of use

Hydrostar motors are used in a wide range of fields as power sources for marine equipment and industrial equipment such as ship winches, agitators that mix chemicals and feed, and crushers that grind wood and tires.
