Runner blade convoluting mechanism

Abstract

The invention provides a runner blade convoluting mechanism. Blades are installed in sliding vane grooves of a turning wheel. Under the action of rotational centrifugal force of the turning wheel or elastic force of springs installed in the sliding vane grooves, the outer arc surfaces of the top ends of the blades are in line contact with the inner arc wall surface of a cylinder body. The structures of the blades are rolling blades or sliding blades, the rolling blades are in a cylindrical shape, and the rolling blades roll in the sliding vane grooves of the rotating wheel. The sliding bladesslide in the sliding vane grooves of the rotating wheel, and the outer arc surfaces and the lower arc surfaces of the sliding blades are of the same center of a circle. Through the technical improvement, a blade meshing control device changes the contact rotary motion between the blades and the cylinder body into the meshing rotary motion, and the rotational speed is not affected by the speed of acontact line. The performance of pumps, hydraulic power machines, pneumatic machines, compressors, expansion power machines and engines in the technical field of fluid machinery is improved.

Description

Technical field [0001] The invention is a runner blade turning mechanism suitable for a rotary positive displacement fluid machine, and relates to the technical fields of mechanical manufacturing such as fans, pumps, hydraulic motors, pneumatic motors, compressors, expansion power machines, and engines. Background technique [0002] The sliding vane rotating mechanism currently used in positive displacement fluid machinery has the advantages of small size, light weight and high volumetric efficiency. It is widely used in fluid machinery such as fans, pumps, compressors, hydraulic pneumatic motors, etc.; the sliding vane rotating mechanism There is high-speed contact friction between the blade and the stator, and the leakage value between the blade and the inner wall of the stator is relatively high, resulting in greater wear and energy loss. In order to solve the above shortcomings, there is an urgent need for a motion mechanism with rolling or meshing motion between the sliding ...
