Title:
HYDRAULIC REVOLVING JOINT
Document Type and Number:
Japanese Patent JPS5517716
Kind Code:
A
Abstract:
PURPOSE:To plan to absorb and relief vibrations and shocks caused by rotation in a power transmission system by sealing a discharge port of a hydraulic pump and transmitting a rotating torque, imposed to an input shaft, to an output shaft. CONSTITUTION:An input shaft 2 and an output shaft 3 are provided coaxially in a pump body 1 and a prime mover is connected to the input shaft 2 while a load is connected to the output shaft 3. An internal gear 7 is coupled to the input shaft 2 and is connected to a suctuon port 11 communicating with an oil tank while a discharge port side is sealedly closed. When the input shaft 2 is driven, oil pressure in an operating chamber between the internal gear 7 and a ring gear 8 becomes high, and the coil pressure reaction force is transmitted to the pump body and the output shaft 3, and thereby, the output shaft 3 is rotated in the same direction as the input shaft. Vibrations and shocks generated by the rotation may be absorbed in a rotating damper of the pump.
