PRESS MOULD FOR FABRICATION OF ELASTOMER ARMATURE FOR STATOR OF GEROTOR-TYPE PROPELLER-DRIVEN HYDRAULIC MACHINE Russian patent published in 2009 - IPC B29C39/18 B29C45/14 B29C45/36 B29C35/02 

FIELD: mechanics.

SUBSTANCE: desired effect is obtained due to utilisation of the proposed press mould designed for fabrication of elastomer armature for the stator of a gerotor-type propeller-driven hydraulic machine and comprising a core with screw-shaped multiple-thread pins; on one of the core sides there is an inlet channel and a moulding channel arranged. Two centring bushings are mounted at the core ends. A stop bushing is fitted onto the core from the inlet and the moulding channel side. Additionally the press mould comprises the tubular shell of the stator being fabricated mounted concentric with the core with the help of the centring bushings. Together with the bushings and the core the shell forms the moulding cavity. One of the centring bushings has at least a single through-hole arranged in it for discharge of air from the moulding cavity. Each centring bushing is represented by a cartridge with a butt-end cross-wall. In the cross-wall there are centring holes arranged to enable the cartridge being mounted onto the core butt-ends and/or onto the stop bushing concentric with the core. The butt-ends of the stator shell outer surface are fitted in the cartridges concentric with the core. A butt-end of the stator tubular shell is located within the core cross plane passing through the moulding channels outlets locations. The other butt-end is support-attached to the cartridge cross-wall positioned opposite the inlet and the moulding channels.

EFFECT: enhancement of output performance, service life duration and operational reliability of gerotor-type propeller-driven hydraulic machines.
