S型齿廓曲线齿轮的重合度研究
Research on Contact Ratio of S-shaped Tooth Profile Gears
摘要
Abstract
Contact ratio is a main factor to influence meshing performance of gear transmission,and it is also a key index to judge continuity and load distribution of gear transmission.Gear with S-shaped tooth profile is developed as a new tooth profile of gear so as to enhance contact strength of gear.In order to further study on it,the formula is deduced to calculate the contact ratio of gear transmission with S-shaped tooth profile,and the change law in contact ratio is discussed varying with the number of teeth,modulus,pressure angle,and derivative coefficient,which is comparing with the involute gear with small number of teeth under the same design parameters.And the results show that the gear with S-shaped tooth profile has a large advantage in contact ratio comparing with the involute gear under the same parameters.关键词
