Abstract

The invention discloses a valve plate of a square and hexagon type non-circular gear planetary gear train hydraulic motor and a hydraulic motor. The shape and the position of a flow distribution hole in the valve plate are accurately designed so that the sectional area of a runner is increased to the maximum degree, the flow resistance is reduced and the working efficiency of the motor is improved.

Description

technical field [0001] The invention relates to hydraulic power equipment, in particular to a valve plate of a four-six type non-circular gear planetary gear train hydraulic motor and a hydraulic motor containing the valve plate. Background technique [0002] The non-circular gear planetary gear train hydraulic motor is a low-speed high-torque hydraulic motor, especially suitable for using emulsion or other liquids with equivalent performance as the working medium, and it also has anti-pollution, high efficiency, low noise, miniaturization, integration, etc. Therefore, it has become the focus of national scientific and technological research in the early 1990s. The core mechanism of the hydraulic motor is the non-circular gear planetary gear train and its distribution structure. The most critical in the design of the distribution structure is the shape, size and position of the distribution hole. The distribution hole controls the entry and exit of the working medium in the ...
