把中间滚动体应用在蜗杆蜗条传动付中能保证移动的高度平稳性和灵敏度,减少磨损和完全消除传动间隙。这种传动付的性能首先取决于回珠槽和反向器的设计。 现有的回珠槽结构,由于长度大和滚珠运动方向急剧改变,回珠槽表面的摩擦和磨损量增大,在截断面不利的条件下或者槽有急转弯 Applying the middle rolling element to the worm and worm drive ensures a high level of stability and sensitivity of movement, reducing wear and eliminating drive clearances altogether. The performance of this drive depends first and foremost on the design of the bead return and reverser. Due to the large length and the drastic change of the direction of the ball movement, the existing back-bead groove structure increases the friction and the abrasion on the surface of the bead groove, and under the unfavorable cross-section conditions or the sharp turn of the groove
