Title:
VANE ASSEMBLED BODY FOR OSCILLATION TYPE HYDRAULIC PRESSURE EQUIPMENT
Document Type and Number:
Japanese Patent JP3913399
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To improve performance of an oscillation type hydraulic pressure equipment by providing a simply-configured vane assembled body, which is composed of a rotor shaft and a vane with satisfactory dimensional accuracy and assembling accuracy as well as securing smooth operation at all times.
SOLUTION: In this oscillation type hydraulic pressure equipment, a vane 2 is provided with a sector-like hydraulic oil chamber on the casing side to a rotor shaft 3. The oscillation type hydraulic pressure equipment is divided by a pair of hydraucli oil chambers which repeatedly alternate between expanding and shrinking by turn according to a relative oscillation displacement between the casing and rotor shaft 3. The vane 2 and rotor shaft 3 are configured separately, while the vane 2 comprises a cylindrical base end portion 4, an attachment portion to the rotor shaft 3, and a vane portion 5 which is integrated with and extends radially from the base end portion 4. Furthermore, a split 7 is provided for opening from inside the vane portion 5 to a hole 6 in the central portion along the base end portion 4. The vane 2 is attached integrally to the rotor shaft 3 by diminishing the bore of the base end portion 4 with a clamping volt 8 which is screwed from a direction perpendicular to the split 7.
