Problems solved by technology
[0003] The purpose of the present invention is to solve the problem that the meshing points between the gear teeth of the cycloid wheel and each needle post are likely to interfere with each other when the existing cycloid hydraulic motor is working, and thus reduce the mechanical efficiency, volumetric efficiency and pressure of the cycloid hydraulic motor To solve the level problem, provide a method for modifying the profile of the cycloidal wheel, which can effectively improve the volumetric efficiency, mechanical efficiency, pressure level and other performance parameters of the cycloidal hydraulic motor on the premise of ensuring the smooth meshing of the cycloidal wheel and the stator

The invention discloses a profile correction method for a cycloidal gear of a cycloid motor. The profile correction method includes firstly, acquiring a workblank of the cycloidal gear by existing processing equipment and technology; secondly, correcting profile correction sections, between tooth tops and tooth roots, on the tooth profile of the cycloidal gear according to theoretical profile correction functions. According to the profile correction method, only two gapless meshing points of each tooth top and corresponding tooth root exist during working to a cycloid hydraulic motor, mutual interference and collision among a plurality of gapless meshing points formed by processing and manufacturing errors of the cycloidal gear are avoided, improvement of sealing property between a high-pressure cavity and a low-pressure cavity of the cycloid hydraulic motor is facilitated, and frictional resistance during rotating of the cycloidal gear is reduced. By the profile correction method, on the premise that the cycloidal gear is ensured to be smoothly meshed with a stator, volumetric efficiency, mechanical efficiency and performance parameters such as pressure rating of the cycloid hydraulic motor can be effectively improved.
Description
Technical field [0001] The invention relates to a processing method of a cycloid motor, in particular to a contour modification method of a cycloid wheel in the cycloid motor. Background technique [0002] The existing cycloid hydraulic motor is also called cycloid gear motor, which mainly includes a stator, a rotor formed by a cycloid inside the stator, and a stator mainly composed of a peripheral stator body and a needle composed of a plurality of needle posts inside the stator body. The teeth are formed, and the cycloidal wheel meshes with the needle teeth. During the working process of the cycloid hydraulic motor, the cycloid wheel moves in the form of revolving and rotating around the center of the stator, and at the same time forms multiple closed cavities with the stator body and the needle column. With the cyclic rotation of the cycloid, each closed volume The cavity completes the sequential switching between high and low pressure. At any position where the cycloidal wh...
