Optimized design of cylinder distribution circle radius for wobble plate compressor
摘要
Abstract
In order to improve the phenomenon of piston ring eccentric wear in oil-free lubricated wobble plate compressors,for wobble plate compressors under two typical types of anti-rotation structures,the motion models of the ball hinge on wobble plate and the connecting rod were constructed,and the optimization design method of cylinder distribution radius based on genetic algorithm with the optimization objective of minimizing the average tilting angle of the connecting rod in the motion period was proposed.The study shows that the best distribution circle radius of cylinder is the same for each phase under the bevel gear anti-rotation structure;and the best distribution circle radius corresponding to cylinder in each phase is different for each phase under the roller-straight groove anti-rotation structure,but the mean value can be used as a uniform distribution circle radius,and at this time the effect on the average tilting angle of the connecting rod in each phase is extremely small,less than 5‰;When the tilting angle of the wobble plate is 25° or less,the optimal design values of the cylinder distribution circle radius of the wobble plate compressor under the two types of anti-rotation structures are almost the same.By applying this optimization design method to a variety of existing wobble plate mechanisms,the average tilting angle of the connecting rod is reduced by nearly 21.4%～28.6%,and the peak piston lateral force is reduced by nearly 19.5%～49.6%.This optimization design method can effectively improve the eccentric wear phenomenon of piston ring.关键词
