The transmission theory of the two teeth difference cycloid gearing planetary drive is analysed.
本文分析了二齿差摆线针轮行星传动的啮合原理和强度计算方法。
The two teeth difference cycloid gearing now is widely applied in the low transmission ratio gearing because of its anti-gluing performance .
二齿差摆线针轮行星传动，由于具有较强的齿面抗胶合能力，因而在小传动比的传动中，得到了广泛的应用。
Methods According to the difference of malocclusion deformity of some teeth, two kinds of corrective brackets were used in turn.
方法根据个别牙齿错牙合畸形不同，在矫治过程中将两种矫治器托槽交互替换使用。
In small tooth difference of inner meshed transmission, there were a few pairs of tooth faces which were apart from each other for a small gap beside the contact point generated by two meshed teeth.
在少齿差内啮合传动中，存在多对接近啮合的小间隙齿面于理论啮合点左右，轮齿受力产生的微小变形使得某些对齿面相互接触进入啮合状态。
