Abstract

The invention discloses a method for optimizing the cycloid gear tooth outline modification amount based on a matlab. The method comprises the first step of calculating the inflection point position of the cycloidal gear tooth outline according to basic parameters of a cycloidal gear, the second step of calculating the optimal modification angle according to the oil film thickness and the inflection point position, the third step of calculating the optimal isometry and the shifting modification amount according to the optimizing function of the matlab, and the fourth step of acquiring testing parameters tested conveniently. Compared with the prior art, the method has the advantages that the analyzing method for improving and optimizing the cycloid gear tooth outline through a MATLAB optimization toolbox by analyzing a mathematical model of cycloidal gear modification is put forward, the optimal modification angle is obtained according to the oil film thickness, the range of the optimal modification amount is found out according to the inflection point position in a meshing area, and the optimal isometry and shifting modification tooth outline is obtained; the calculation period of the tooth outline modification amount is greatly shortened, the number of teeth meshed at the same time is guaranteed, the stability of transmission is guaranteed, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of cycloidal wheels, in particular to a method for optimizing the modification amount of cycloidal wheel tooth profile based on matlab. Background technique [0002] The planetary cycloid reducer is a reduction mechanism that applies the principle of planetary transmission and adopts cycloid pin-tooth meshing. Due to its unique advantages of advanced design and novel structure, it has been widely used in military industry, aerospace, metallurgy, lifting and transportation, etc. [0003] The cycloid pinwheel meshing pair is the core component of the planetary cycloid reducer. The cycloidal pair belongs to the one-tooth difference internal meshing gear set. Theoretically, the conjugate tooth profile has no radial clearance, and the number of meshing points is always equal to the number of pinwheel teeth. The meshing line is a symmetrical closed curve. In actual application of cycloi...
