发布日期:2017年12月13日

包括同轴状并列配置的圆环状的第一刚性齿轮 2 和第二刚性齿轮 3。在这些第一刚性齿轮 2、第二刚性齿轮 3 的内侧同轴状地配置有能与第一刚性齿轮 2、第二刚性齿轮3 双方啮合的圆筒状的柔性齿轮 4。柔性齿轮 4 的轴向宽度为包含第一刚性齿轮 2、第二刚性齿轮 3 的尺寸。

A circular ring shaped first rigid gear 2 and a second rigid gear 3. A cylindrical flexible gear 4, which is able to mesh with the first rigid gear 2 and second rigid gear 3, is arranged in the inner side of the first rigid gear 2 and the second rigid gear 3. The axial width of the flexible gear 4 is the size of the first rigid gear 2 and the second rigid gear 3.

在柔性齿轮 4 的内侧以同轴状并列配置的状态嵌入着具有楕圆形轮廓的两个波发生器、即第一波发生器 5 和第二波发生器 6。第一波发生器 5 位于与第一刚性齿轮 2 相对的位置,将柔性齿轮 4 的轴向上的一侧的第一柔性齿轮部分 4a 挠曲成楕圆形,在该楕圆形的长轴方向的两端位置上使第一柔性齿轮部分 4a 与第一刚性齿轮 2 啮合。同样地,第二波发生器 6 位于与第二刚性齿轮 3 相对的位置,将柔性齿轮 4 的轴向上的相反侧的第二柔性齿轮部分 4b 挠曲成楕圆形,在该楕圆形的长轴方向的两端位置上使第二柔性齿轮部分 4b与第二刚性齿轮 3 啮合。
In the inside of the flexible gear 4 coaxial parallel state configuration with embedded circular outline of the Hahn Banach extension two wave generator, namely the first wave generator 5 and second wave generator 6. The first wave generator 5 is located in the first position and the 2 relatively rigid gear, first gear part 4A deflection flexible side axial flexible gear 4 of the Hahn Banach extension at both ends of the round round, the long axis of the Hahn Banach extension 4A with the first part of the first flexible gear meshing rigidity gear 2. Similarly, the second wave generator 6 is located in the second position with 3 relatively rigid gear, 4b deflection second flexible gear part on the opposite side of the axial flexible gear 4 of the Hahn Banach extension at both ends of the round round, the long axis of the flexible gear Hahn Banach extension second 4B and second 3 rigid gear meshing.
此处,在将第一刚性齿轮 2 的齿数设为 Nc1、将第二刚性齿轮 3 的齿数设为 Nc2、并将柔性齿轮 4 的齿数设为 Nf 时,设定成 :Nc2 > Nc1 Nc1 > Nf 在本例中,例如各齿轮的齿数之差为 2 的倍数,设定成 :[0030] Nc2 = Nc1+2m(m :正整数 ) Nc1 = Nf+2n(n :正整数 ) 一般而言,齿数差为 2(n = 1,m = 1)。
Here, the number of teeth set in the first rigid gear 2 is set to Nc1, the number of teeth of second rigid gear 3 to Nc2, and the number of teeth of flexible gear 4 is set to Nf, Nc1: Nc2 > Nc1 > Nf in this case, for example, number of teeth of each gear is the difference of 2 multiple set: [0030] Nc2 = Nc1+2m (M: integer) Nc1 = Nf+2n (n: integer) in general, the tooth number difference was 2 (n = 1, M = 1).

在这样构成的组合型波动齿轮减速机 1 中,当第一波发生器 5 高速旋转时,柔性齿轮 4 与第一刚性齿轮 2 的啮合位置在周向上移动,由于它们的齿数差,因此产生大幅度减速的相对旋转。由于第一刚性齿轮 2 被固定,因此柔性齿轮 4 旋转。柔性齿轮 4 的另一侧通过第二波发生器与齿数比第一刚性齿轮 2 多的第二刚性齿轮 3 啮合。因此,通过柔性齿轮4 的旋转,作为旋转输出单元的第二波发生器 6 加速旋转,整体上可实现将高速输入旋转以低减速比减速后得到的减速旋转输出。
In such a combined wave gear reducer 1, when the first wave generator 5 is rotating at high speed, the engaging position of the flexible gear 4 and the first rigid gear 2 moves in a circumferential direction, and the relative rotation of a large deceleration is caused by their tooth number difference. As the first rigid gear 2 is fixed, the flexible gear 4 rotates. The other side of the flexible gear 4 is meshed with the number of teeth by the second wave generator and the number of the second rigid gear 3 of the first rigid gear more than 2. Therefore, through the rotation of the flexible gear 4, as the second wave generator 6 of the rotary output unit, it accelerates the rotation. It can achieve the deceleration and rotation output of the high speed input rotation and the slow deceleration ratio.
