Title
(EN) Transmission
(ZH) 变速装置
Abstract
(EN) The invention discloses a transmission (10), in which an internal/external gear (15) is made to revolve along an eccentric guide part (29) while rotating in accordance with the speed difference between an input means (12) and an eccentric guide plate (13), a gear linkage mechanism is provided with the following: a circular disc part (21) and external teeth (22) provided on the input means (12); a second cylindrical guide part (31) provided, on one side of the internal/external gear (15), along the same axis as a first cylindrical guide part (30); an external gear (18) that is fitted around the input means (12) so as to be able to rotate and has external teeth (38) that are the same shape as the external teeth (22) on the input means (12) and mesh with the internal teeth (33) of the internal/external gear (15); and an internal gear (19) that is sandwiched between the circular disc part (21) and the internal/external gear (15), revolves together with the internal/external gear (15), has internal teeth (40) that mesh with both of the aforementioned sets of external teeth (22 and 38), and has a guide ring (39) that is guided by the second cylindrical guide part (31). This makes it possible to change gear in the same manner for both forward rotation and reverse rotation and allows a compact, simple structure with a low component count.
(ZH) 一种变速装置(10),其与输入构件(12)和偏心引导板(13)的转速差相应地,使内外齿轮(15)一边旋转一边沿偏心引导部(29)环绕,其中,齿轮连结机构具备:圆板部(21)和外齿(22),它们设置于输入构件(12);第2圆筒引导部(31),其以轴心与第1圆筒引导部(30)一致的方式设置于内外齿轮(15)的一侧;外齿轮(18),其以能够自如旋转的方式嵌装于输入构件(12)并具有外齿(38),该外齿(38)为与输入构件(12)的外齿(22)相同的形状且与内外齿轮(15)的内齿(33)啮合;以及内齿轮(19),其具有与外齿(22)和外齿(38)啮合的内齿(40)以及被第2圆筒引导部(31)引导的环状引导部(39),以被圆板部(21)和内外齿轮(15)夹着的方式配设并与内外齿轮(15)一起环绕。由此,无论在正转还是反转中都能够同样地进行变速,并且部件数量较少,紧凑且结构也简单。
