蜗轮蜗杆传动具有减速比大、结构紧凑等优点,是一种应用十分普遍的传动。然而由于蜗杆与蜗轮的滑动摩擦系数较大,机械效率较低,故其磨损快、寿命短。因此,为了保留这种传动的优点,去其不足之处,我们提出了“滚子轮蜗杆传动”。一、滚子轮蜗杆传动的原理在普通蜗轮蜗杆传动中,在其轮齿螺旋线的切线方向具有一滑动速度V_P,如图1所示。由于在传动中两齿面间产生滑动,故其当
Worm gear reducer with a large, compact, etc., is a very common application of the drive. However, due to the worm and worm sliding friction coefficient larger, lower mechanical efficiency, so wear fast, short life. Therefore, in order to retain the advantages of this drive, to its shortcomings, we put forward the “roller worm drive.” First, the principle of the roller wheel worm drive In ordinary worm gear transmission, in the tangential direction of the helical gear has a sliding speed V_P, as shown in Figure 1. Due to the sliding between the two teeth in the transmission, so when
