The application provides a involute variable-thickness gear pump, and belongs to the technical field of fluid machinery. The gear pump adopts a pair of involute variable-thickness driving gears and driven gears to form a parallel shaft external meshing pair, the thickness of the gears continuously changes along the width direction, and the meshing gap can be self-adaptively adjusted through axial position fine adjustment; the gear pair forms a gradual meshing area along the axial direction, has a dynamic thickness compensation effect, can significantly reduce fluid oil trapping, reduce flow pulsation, improve volumetric efficiency and operation stability. The application has simple structure and strong adaptability, can be compatible with straight teeth / oblique teeth, external meshing / interior meshing structure, and is suitable for high-pressure, low-noise, long-life hydraulic and fluid conveying systems.
