摘要

自升式钻井平台以其独有优势在海洋资源开发进程中占有重要地位。自升式平台升降系统通常采用超大模数、少齿数的齿轮轴和齿条传动,其中齿轮齿条作为承载部件,需要有优秀的耐承压能力才能维持重载升降过程安全平稳。基于ANSYS Workbench对自升式平台齿轮齿条进行分析,通过改变压力角和齿条宽度两项参数,计算出其对自升式平台齿轮齿条机构接触应力的影响,得出"加强齿轮齿条根部的强度、适当增加齿条齿宽、在允许范围内增加齿轮压力角,能够有效降低齿条磨损"的结论。
        With its unique advantages, jack-up rigs play an important role in the development of marine resources. The self-elevating platform lifting system usually adopts gear shaft and rack transmission, and has the characteristics of large modulus and few teeth. Among them, the rack and pinion as the load-bearing component needs to have excellent pressure-resistance ability to maintain the safety and stability of the heavy-duty lifting process. Based on ANSYS Workbench, the self-elevating platform rack and pinion are analyzed. By changing the two parameters of pressure angle and rack width, the influence of the two factors on the contact stress of the self-lifting platform rack and pinion mechanism is calculated. It is concluded that the strength of the root of the rack and pinion should be strengthened, the tooth width of the rack is appropriately increased, and the gear pressure angle is increased within the allowable range, which can effectively reduce the rack wear.
