你好!译文供参考.蜗杆蜗轮传动机构具有较大的传动比,零件数目少,整体结构很紧凑,在传动过程中产生的冲击载荷小,传动平稳,噪音低,还具有自锁性等优点,但缺点是摩擦磨损较大,蜗轮制造成本高.以斜齿轮来代替蜗轮组成圆柱蜗杆斜齿轮传动机构就能很好的克服这种缺点并保留原有的优点.The advantages of worm gear transmission mechanism are high transmission ratio, less number of parts, overall compact structure, low impact load generated during transmission, smooth transmission, low noise and self-locking, and the disadvantages are high frictional wear and high cost for manufacturing worm gear. The cylindrical worm helical gear transmission mechanism which uses helical gear instead of the worm gear perfectly overcomes the disadvantages while retains the (intrinsic) advantages..
