Abstract

The invention discloses a cycloidal gear tooth profile modification method based on a genetic algorithm and a particle swarm combination algorithm. A standard cycloidal tooth profile which is completely conjugated with the pin wheel is ensured to be close to the main meshing section of the cycloidal tooth profile as much as possible, and a small meshing gap is generated at the non-main meshing section close to the tooth crest and the tooth root, so that the lubrication requirement is ensured, and various error factors are compensated. Based on the genetic algorithm and the particle swarm algorithm have the advantages of taking the length of the algorithm and supplementing the length of the algorithm, and according to the present invention, the convergence speed of the algorithm is increased, the problem of insufficient global search capability caused by too fast convergence can be avoided, and the contradiction between the convergence speed and the global search capability can be effectively overcome, so that although a meshing gap exists in the meshing process of the modified cycloidal gear, the return difference is very small, the requirement that multiple teeth participate in meshing to guarantee good meshing performance can be met at the same time, the calculation period of the cycloidal gear modified through the combination algorithm is short, and the whole optimization process is completed within very short time.

Description

technical field [0001] The invention belongs to the field of design and manufacture of cycloidal gears, in particular to a cycloidal gear tooth profile modification method based on genetic algorithm and particle swarm combination algorithm. Background technique [0002] Since 2013, my country has become the largest robot consumer market in the world. Because of the advantages of large transmission ratio, high transmission efficiency, high motion precision, small backlash, low vibration, high rigidity and high reliability, RV reducers are regarded as One of the core components of industrial robots is in great demand. [0003] The cycloidal wheel is the core part of the RV reducer, and its precision is directly related to the overall performance of the RV reducer, such as transmission accuracy and stability. In order to compensate for the manufacturing and installation errors of the cycloidal wheel, as well as the force deformation and lubrication requirements during the meshi...
