Problems solved by technology
[0002] In actual engineering applications, the cycloidal wheel does not use the standard tooth profile curve as the tooth profile curve, because the cycloidal wheel processed according to the standard tooth profile will be difficult to assemble, and the friction and heat during the work process will cause the cycloidal wheel and With the expansion of the pin teeth, the tooth profile of the expanded cycloid wheel and the pin teeth will no longer be a conjugate curve, so that the transmission cannot be carried out. Therefore, in order to compensate for manufacturing errors, facilitate assembly and ensure lubrication, the gap between the cycloid wheel and the pin teeth need to have clearance

The invention relates to a cycloidal gear tooth profile modification method. The method comprises the following steps: establishing a cycloidal gear optimization mathematical model; solving the cycloidal gear optimization mathematical model by using a genetic algorithm to obtain an optimal equidistant modification amount and a shift modification amount; carrying out stress analysis on the teeth with different tooth numbers according to the obtained equidistant modification amount and the displacement modification amount to obtain the contact tooth number of the tooth number with the maximum stress; and comparing the obtained contact tooth number with the expected contact tooth number, and if the expected contact tooth number is met, outputting a result. The cycloidal gear design efficiencycan be improved.
Description
technical field [0001] The invention relates to the technical field of design and manufacture of a cycloidal wheel, in particular to a method for modifying the tooth profile of a cycloidal wheel. Background technique [0002] In actual engineering applications, the cycloidal wheel does not use the standard tooth profile curve as the tooth profile curve, because the cycloidal wheel processed according to the standard tooth profile will be difficult to assemble, and the friction and heat during the work process will cause the cycloidal wheel and With the expansion of the pin teeth, the tooth profile of the expanded cycloid wheel and the pin teeth will no longer be a conjugate curve, so that the transmission cannot be carried out. Therefore, in order to compensate for manufacturing errors, facilitate assembly and ensure lubrication, the gap between the cycloid wheel and the pin teeth There needs to be gaps. In engineering applications, the meshing gap between the cycloid wheel...
