OUTPUT SHAFT OF CYCLOID HYDRAULIC MOTOR AND SHAFT VALVE FLOW-DISTRIBUTION CYCLOID HYDRAULIC MOTOR
An output shaft (1) of a cycloid hydraulic motor and a shaft valve flow-distribution cycloid hydraulic motor having same, belonging to the technical field of mechanical transmission. The main body of said output shaft (1) consists of a large-diameter section (1-2) assembled in a casing (10) of the cycloid hydraulic motor and a small-diameter section (1-1) extending from the casing. The inner hole of the large-diameter section (1-2) is provided with a structure drivenly engaged with a coupling shaft (21) of the hydraulic motor, and the outer circumferential surface of the large-diameter section is provided with a movable matching part (1-2-1) matched with the inner hole of the casing (10). The movable matching part (1-2-1) is provided with at least two sections of circumferentially discontinuous oil grooves (1-2-2); the groove bottom of the discontinuous oil groove (1-2-2) consists of an eccentric arc section, the center O' of which deviates from the center O of the excircle of the movable matching part with the process eccentricity e; the radius R of the eccentric arc section is greater than the radius r of the excircle of the movable matching part. The output shaft and the hydraulic motor can improve the working efficiency and reduce the manufacture cost, as well as can better form an oil film, enhance the bearing capacity of the radial force, and ensure lubrication and seal.
Disclosed is a cycloidal pinwheel pair with uniform contact and one tooth difference, belonging to the technical fields of cycloidal hydraulic motors and fully hydraulic diverters. The cycloidal pinwheel pair comprises a stator (01) and a rotor (02). Each gear tooth profile of the rotor (02) has a modified recess provided symmetrically on both sides; the starting point (A) of the modified recess on one side of the gear tooth profile is located between a first point (11') and a second point (26') determined by the location of the two limit positions, the end point (B) of the modified recess is located between a third point (16') and a fourth point (22') determined by the location of the two limit positions, thereby putting adjacent high-pressure chambers and adjacent low-pressure chambers in communication with each other. Since using a modified recess supersedes the original clearance in the design for error compensation, the former internal leakage between high and low pressure chambers is effectively avoided, significantly improving volume efficiency and mechanical efficiency, while the structure is extremely simple and can be made by form grinding in one go, and the technological efficiency is excellent.
