摘　　要：爬升齿轮作为自升式平台齿轮齿条式升降系统的重要零件,其结构设计的关键是齿轮参数选择和齿形设计。通常选用大模数、小齿数、大压力角和正变位系数等齿轮参数,而齿形设计则需考虑重合度和法向侧隙对爬升齿轮与桩腿齿条正常啮合运行的影响,以满足齿轮齿条连续运行的基本要求。齿形设计完成后采用3种方法对爬升齿轮齿部进行强度分析,并进行了比较说明,指出有限元法可作为大模数齿轮强度校核的有效方法。The climbing pinion is an important part of the jacking system of a self-elevating platform. The key of structural design of climbing pinions is gear parameter selection and tooth shape design. Gear parameters such as large modulus,small teeth,large pressure angle and positive modification coefficient are usually selected. In tooth profile design,the influence of contact ratio and normal backlash on the normal meshing operation of climbing pinions and leg racks should be considered so as to meet the basic requirements of continuous operation of pinions and racks. After the tooth profile design is completed,three methods are used to analyze the tooth strength of climbing pinions,and a comparison is conducted. It is pointed out that the finite element method can be used as an effective method for checking the strength of large module gears.
