| 摘 要： | 针对石油井下减速器受径向尺寸限制难以设计的现状,比较了几种减速器设计方案的优劣,设计了一种与现有并下动力钻具配合使用的NN型闭式少齿差外齿输出减速器,采用由油润滑的两级少齿差齿轮副传动,将井下涡轮的高转速、小扭矩的旋转运动,变换成钻头上的低转速大扭矩的旋转运动。轮齿弯曲强度和接触强度增强,能满足井下机械重载运行的需要。该减速器具有结构紧凑、运行平稳、承载能力强、减震性能好、密封性能与传动效率好、使用寿命长的优点。

| Abstract: | Considering the actuality of hard to design the downhole reducer because of the restriction of diameter,designed a new type reduc- er-less teeth difference planetary transmission ＆ NN style closed reducer,being used with drive drilling tool,after having compared several designations.It may convert the turbine＇s high rotate speed and little torque to the bit＇s low rotate speed and great torque.The bending strength and contact strength of the tine is strong enough to meet the needs of downhole mechanical heavy burden.This reducer earns the virtue of cramped construction,calm function, heavy burden, great shock absorption and seal capacity,long working life. |
