    • PURPOSE:To prevent the increase in transmission loss due to bite between the teeth a driving gear and a floating ring gear, by a method wherein each of the two gears is rigidly fitted with a circular disk having a diameter equal to that of the intermeshing pitch circle of the gears, and the disks are brought into rolling contact with each other. CONSTITUTION:The driving gear 2 is rigidly fitted with the disk 7 having an outside diameter approximately equal to the diamter of the intermeshing pitch circle 6, and the floating ring gear 3 is rigidly fitted with a plate-shaped ring 8 having an inside diameter approximately equal to the diameter of the pitch circle 6. The outside periphery of the disk 7 and the inside periphery of the ring 8 are brought into rolling contact with each other. Accordingly, the driving gear 2 and the ring gear 3 are meshed properly at the pitch circle 6 without occurrence of any contact or bite between the tooth crest part of one of them and the bottom land part of the other, so that the transmission efficiency can be enhanced.
    • 目的:为了防止由驱动齿轮和浮动齿圈之间的咬齿引起的传输损耗的增加,通过一种方法,其中两个齿轮中的每一个刚性地装配有直径等于啮合间距的直径的圆盘 齿轮的圆圈和盘彼此滚动接触。 构成:驱动齿轮2刚性地装配有具有与啮合节圆6的直径近似相等的外径的盘7,并且浮动环形齿轮3刚性地装配有内径约为的板状环8 等于节圆6的直径。盘7的外周和环8的内周彼此滚动接触。 因此,驱动齿轮2和环形齿轮3在节圆6处适当地啮合,而不会在它们中的一个的齿顶部分和另一个的底部部分之间发生任何接触或咬合,从而传动效率可以 加强。
