参考图 1， 所述的动力源为电机 100， 电机 100的转子 23作为动力源的旋转体得 到带有齿轮减速装置的电机， 图 1示出了带有齿轮减速装置的电机第一种具体实施方式 ' 。 ， ， 机 100为内转子电机 100，具体包括电机外壳（图未标记）、 电机定子 22和电机转子 23 ; 电机定子 22固定于电机外壳上， 电机转子 23同轴安装于电机定子 22内侧， 电机转子 23上设置有多个轴孔， 电机转子 23的上下两端还设置有上端盖和下端盖； 可以通过锁 紧螺钉将下端盖、 电机定子 22和上端盖固定； 在上端盖的上方还固定连接有安装板， 通过安装板可以将带有齿轮减速装置的电机安装在外接设备上。
所述带有齿轮减速装置的电机还包括输出轴 11， 输出轴 11同轴心设置于所述电机 转子 23的内部， 输出轴 11和电机转子 23之间可以设置含油轴承， 输出轴 11径向限定 电机转子 23， 并通过含油轴承实现输出轴 11和电机转子 23之间的相对旋转。
所述带有齿轮减速装置的电机还包括齿轮减速装置 200， 所述齿轮减速装置 200包 括输入齿轮轴 31、 第一齿轮 321、 第二齿轮 322、 中间齿轮 331和输出齿轮 332; 输入 齿轮轴 31插装于电机转子 23的轴孔内，输入齿轮轴 31和电机转子 23之间设置有含油 轴承，通过含油轴承输入齿轮轴 31和电机转子 23之间可以实现相对旋转；第一齿轮 321 和第二齿轮 322固装在输入齿轮轴 31的两端； 第一齿轮 321和中间齿轮 331啮合， 第 二齿轮 322和输出齿轮 332啮合。
中间齿轮 331套装在输出轴 11上， 与输出轴 11不固定； 输出齿轮 332与输出轴 11 固接， 可以通过圆柱销固定连接； 输出齿轮 332和下端盖之间还设置有滚动轴承， 可以 实现输出齿轮 332和下端盖之间的相对旋转，且同时限制输出齿轮 332的轴向和径向移 动。
这里需要说明的是， 可以在电机 100转子内插装多个输入齿轮轴和与之配合的第一 齿轮和第二齿轮； 电机 100转子的轴孔个数优选为 2~4个， 多个输入齿轮轴的布置可以 使得电机 100和齿轮减速装置 200的组合在工作时更加稳定； 当然也可以只在电机 100 转子上插装一个齿轮轴和与之配合的齿轮。
本实施方式工作时， 电机 100通电后， 驱动电机转子 23转动， 同时驱动与电机转 子 23连接的输入齿轮轴 31及与输入齿轮轴 31固装的第一齿轮 321和第二齿轮 322公 转， 由于中间齿轮 331与第一齿轮 321啮合且存在齿差， 可同时驱动输入齿轮轴 31 自 转， 通过第二齿轮 322与输出齿轮 332的啮合驱动输出齿轮 332转动， 最后驱动与输出 齿轮 332固接的输出轴 11转动； 由于第一齿轮 321、 第二齿轮 322、 中间齿轮 331和输 出齿轮 332之间存在齿差关系， 所以输出齿轮 332和电机转子 23之间会产生转速差， 驱动输出轴 11低速输出。
这里需要说明的是， 第一齿轮 321、 第二齿轮 322、 中间齿轮 331和输出齿轮 332 之间的齿差关系可以根据实际所需减速比调节确定。 体实施方式中， 中间齿轮 33 1和输出齿轮 332均
图 2至图 10所示的实施方式均为当所述的动力源为电机 100， 电机 100的转子 23 作为动力源的旋转体得到带有齿轮减速装置的电机时的实施方式。
参考图 2， 在第二种具体实施方式中， 所述齿轮减速装置 200包括双联齿轮 32、 中 间齿轮 331和输出齿轮 332; 双联齿轮 32套装在输入齿轮轴 3 Γ 上， 中间齿轮 331和 输出齿轮 332分别与双联齿轮 32的第一级齿轮 321和第二级齿轮 322啮合； 中间齿轮 331套装在输出轴 11上， 与输出轴 11不固定， 输出齿轮 332与输出轴 11固定连接； 其 中， 中间齿轮 331和输出齿轮 332均为外齿轮。
在第二种具体实施方式中， 输入齿轮轴 3 Γ 固定插装在电机转子 23上， 双联齿轮 32和输入齿轮轴 3 Γ 之间可以相对旋转， 当驱动电机转子 23转动时， 同时驱动双联齿 轮 32公转且自转，根据双联齿轮 32的第一级齿轮 321、第二级齿轮 322与中间齿轮 331、 输出齿轮 332之间的齿差关系同样可以达到输出轴 11低速输出的目的。
当然，也可以将输入齿轮轴 3 Γ 与电机转子 23转动连接，双联齿轮 32与输入齿轮 轴 3 Γ 固定连接， 同样可以实现输出轴 11低速输出。
在第二种具体实施方式或前述第一种具体实施方式中， 所述中间齿轮 331可以为外 齿轮， 也可以为内齿圈， 所述输出齿轮 332可以为外齿轮， 也可以为内齿圈， 从而使所 述齿轮减速装置 200可以有以下几种不同的实施方式。
参考图 3， 在第三种实施方式中， 输入齿轮轴 31转动插装于电机转子 23内， 第一 齿轮 321和第二齿轮 322固装在输入齿轮轴 31 的两端； 其中， 所述中间齿轮 331和所 述输出齿轮 332均为外齿轮。
参考图 4， 在第四种实施方式中， 输入齿轮轴 31转动插装于电机转子 23内， 第一 齿轮 321和第二齿轮 322固装在输入齿轮轴 31的两端； 其中， 所述中间齿轮 331为内 齿圈， 所述输出齿轮 332为外齿轮。
参考图 5， 在第五种实施方式中， 输入齿轮轴 31转动插装于电机转子 23内， 第一 齿轮 321和第二齿轮 322固装在输入齿轮轴 31的两端； 其中， 所述中间齿轮 331为外 齿轮， 所述输出齿轮 332为内齿圈。
参考图 6， 在第六种实施方式中， 输入齿轮轴 3 Γ 与电机转子 23固定连接， 双联 齿轮 32和输入齿轮轴 3 Γ 之间可以相对旋转， 中间齿轮 331和输出齿轮 332分别与双 联齿轮 32的第一级齿轮 321和第二级齿轮 322啮合； 其中， 所述中间齿轮 331为内齿 圈， 所述输出齿轮 332为外齿轮。
由于双联齿轮 32 两级齿轮的齿数不同， 所以还可以将双联齿轮 32 的第一级齿轮 32Γ 与输出齿轮 332啮合， 第二级齿轮 322 ' 与中间齿轮 331啮合， 其中中间齿轮 331 V:/ 3 l ¾i围， 332 ， 万 ， ^ /尸丌不。
上述几种实施方式在工作过程中与第一种具体实施方式的传动原理相同，这里不再 赘述。
需要指出的是， 所述齿轮减速装置 200除了上述几种具体实施方式外， 当然还可以 有其他的具体实施方式， 只要可以实现差动减速， 使输出轴和电机 100转子可以产生转 速差即可。
实际使用中， 有些外接设备在不同的工况下要求输出轴有不同的转速， 如洗衣机， 在洗涤工况下需要输出轴低速输出， 在脱水工况下需要输出轴可以高速输出， 使得洗涤 物可以完全被脱水。 为了实现外接设备不同工况的需求， 可以对上述带有齿轮减速装置 的电机做出进一步的改进。
进一步地， 所述带有齿轮减速装置的电机还包括离合机构 4， 离合机构 4设置于齿 轮减速装置 200和电机转子 23之间， 以便实现低速输出和高速输出的转换。
所述离合机构 4可以为电磁离合机构， 也可以为机械离合机构。 下面以电磁离合机 构为例进行说明。
具体的电磁离合机构可以参见本申请人的在先申请公开的电磁离合机构， 申请号为 CN201210084877. 4 , 同时电磁离合机构与其他部件的连接关系可以为： 电磁离合机构的 离合齿圈可以与中间齿轮 331啮合且轴向滑动连接， 安装板作为上啮合部件， 转子作为 下啮合部件。
这里需要说明的是， 离合齿圈和中间齿轮 331在任何工况下均处于啮合状态， 且两 者之间不能产生相对旋转。 当电磁离合机构通电后， 离合齿圈可以克服弹簧的弹力通过 中间齿轮 331轴向向上滑动， 使得离合齿圈和安装板卡合， 此时电机 100通电后， 可以 通过齿轮减速装置 200实现输出轴 11低速输出； 当电磁离合机构断电后， 在弹簧的回 复弹力作用下，离合齿圈通过中间齿轮 331轴向向下滑动，使得离合齿圈与安装板脱开， 同时与电机转子 23的卡合， 齿轮减速装置 200自锁， 此时电机 100通电后， 输出轴 11 和电机转子 23同速转动， 实现高速输出。
在工作过程中， 电机转子 23和输出轴 11转动时， 不可避免地会产生摩擦， 为了减 少摩擦， 可以在电机转子 23和输出轴 11之间设置平面轴承， 以减缓电机转子 23和输 出轴 11之间的转动摩擦， 延长工作寿命。
还可以对上述带有齿轮减速装置的电机做出更进一步的改进。
进一步地， 所述带有齿轮减速装置的电机还包括输出轴套 12， 所述输出轴套 12套 装在输出轴 11上， 输出轴套 12和输出轴 11之间可以设置含油轴承， 使输出轴套 12和 输出轴 11之间可以实现相对旋转。 八种实施方式中， 齿轮减速装置 200包括插装于电机转子 23内的输入齿轮轴 31， 固装 在输入齿轮轴 31两端的第一齿轮 321和第二齿轮 322， 第一齿轮 321与中间齿轮 331 啮合， 第二齿轮 322与输出齿轮 332啮合； 输出齿轮 332与输出轴 11固接； 中间齿轮 331和输出齿轮 332均为内齿圈。
中间齿轮 331与在输出轴套 12—端固定连接； 离合机构 4设置在输出轴套 12和电 机转子 23之间， 具体地， 离合机构 4的离合齿圈可以与中间齿轮 331啮合且轴向滑动 连接， 也可以通过花键套与输出轴套 12啮合且轴向滑动连接。 需要说明的是， 离合齿 圈不管是通过中间齿轮 331还是花键套与输出轴套 12连接， 在任何工况下， 均与中间 齿轮 331或花键套啮合且不能相对旋转。 在离合机构通电或断电作用下， 所述离合齿圈 可以与电机转子 23卡合或断开连接。
当离合齿圈与电机转子 23卡合时， 中间齿轮 331与电机转子 23锁死， 使齿轮减速 装置 200自锁，输出轴 11、齿轮减速装置 200、输出轴套 12和电机转子 23同转速输出。
当离合齿圈与电机转子 23断开连接时， 可以使离合齿圈与电机 100的固定件， 如 安装板卡合， 使得与离合机构 4连接的输出轴套 12处于固定状态， 通过齿轮减速装置 200, 输出轴 11可以实现低速输出；
此时，也可以使离合齿圈不与电机 100的固定件卡合，使离合齿圈处于不固定状态， 与离合齿圈连接的输出轴套 12也处于不固定状态， 在输出轴 11低速输出的同时， 输出 轴套 12也以一定的速比低速输出， 即可以实现复合动力输出。 这里需要说明的是， 当 输出轴 11 和输出轴套 12既可以是同向低速输出， 也可以是反向低速输出。 输出轴 11 和输出轴套 12的转向相同或相反， 取决于齿轮减速装置 200齿差比值的正负值， 在实 际应用中， 可以根据需要设定齿轮减速装置 200的齿差关系。
这里还需要说明的是， 本第八种实施方式所述的输出轴套的带有齿轮减速装置的电 机的齿轮减速装置 200同样可以有其他如图 1-7任意所示的具体实施方式， 具体如中间 齿轮 331和输出齿轮 332同样可以为内齿圈， 也可以为外齿轮； 也可以用双联齿轮来替 换第一齿轮 321和第二齿轮 322实现相同的功能。
进一步地， 当本第八种实施方式所提供带有齿轮减速装置的电机应用于洗衣机领域 作为洗衣机驱动器时， 可以将以上实施方式所述的输出轴 1 1 成为洗衣机的洗涤轴， 输 出轴套 12成为洗衣机的脱水轴， 并通过离合机构 4实现洗涤和脱水工况的转换， 具体 为：
当离合齿圈与电机转子 23断开连接时， 可以使离合齿圈与电机 100的固定件， 如 安装板卡合， 与离合齿圈连接的输出轴套 12处于固定状态， 通过齿轮减速装置 200, 输 田 实现低速输出， 即实现洗衣机的单驱动方式； 可以 ¾机 100 的固定件卡合， 使离合齿圈处于不固定状态， 与离合齿圈连接的输出轴套 12也处于不 固定状态， 在输出轴 11低速输出的同时， 输出轴套 12也以一定的速比低速输出， 即可 以实现复合动力输出， 即实现洗衣机的匀动力驱动方式， 实现洗涤功能。
当离合机构 4的离合齿圈与电机转子 23卡合时，中间齿轮 331与电机转子 23锁死， 使齿轮减速装置 200自锁， 输出轴 11、 齿轮减速装置 200、 输出轴套 12和电机转子 23 同转速输出， 实现脱水功能。
进一步地， 上述实施方式均为带有齿轮减速装置 200的内转子电机 100， 本发明当 然还可以包括带有齿轮减速装置 200的外转子电机 100的实施方式， 参见图 9， 图 9为 本发明所提供带有齿轮减速装置的电机第九种具体实施方式的传动示意图， 在该种实施 方式中， 该带有齿轮减速装置的电机包括电机 100本体， 所述电机 100本体为外转子电 机 100， 具体包括电机定子 22和电机转子 23， 电机转子 23同轴心设置于电机定子 22 外侧， 其它相关结构可参见第八种实施方式， 同时其所述的齿轮减速装置 200也可同本 发明中第一种至第七种中的任意一种实施方式。

需要指出的是， 可以通过改变离合机构 4的固定方式实现普通输出和复合动力 （也 叫匀动力） 输出。
具体地， 当离合齿圈 41与电机转子 23断开连接时， 可使离合齿圈 41与定子安装 盘 221卡合， 此时与离合齿圈 41连接的中间齿轮 331和脱水轴 52处于固定状态， 从而 在洗涤工况时只有洗涤轴 51低速输出为普通洗涤输出， 也称为洗衣机单驱动方式，； 当 离合齿圈 41与电机转子 23断开连接且不固定， 这里的不固定是指离合齿圈 41不与任 何处于固定状态的部件卡合， 即与离合齿圈 41连接的中间齿轮 331和脱水轴 52也处于 不固定状态， 此时在洗涤轴 51低速输出的同时， 脱水轴 52也按一定的速比低速输出， 即可以实现复合动力输出， 也称为洗衣机匀动力驱动方式， 这里需要说明的是， 洗涤轴 51和脱水轴 52既可以同转向低速输出， 也可以反向输出。 洗涤轴 51和脱水轴 52的转 向相同或相反， 取决于齿轮减速机构齿差比值的正负值， 在实际应用中， 可以根据需要 设定齿轮减速机构的齿差关系。
进一步具体地， 在离合齿圈 41 在洗涤工况时不进行固定时， 且当应用的洗衣机为 波轮 400式或搅拌式洗衣机时，所述的波轮 400式或搅拌式洗衣机包括搅拌器 (波轮 400 为搅拌器的一种） 和内桶 500， 其洗涤方式为: Ί述的搅拌器与内桶 500分别与齿轮减 速装置 200的动力输出端连接， 洗衣机通过离合机构进行洗涤和脱水工况的转换， 洗涤 工况时. 搅拌器和内桶 500双向旋转， 脱水工况时， 搅拌器和内桶 500同向旋转； 洗涤 工况时， 所述的内桶 500与搅拌器随机根据阻力分配关系即时确定转速比， 并在转速比 . > >T , ~ ι
¾t订 Ι。」疋 ， 。
进一步具体地， 在离合齿圈 41在洗涤工况时进行固定时， 且当应用的洗衣机为波 轮 400式或搅拌式洗衣机时， 所述的波轮 400式或搅拌式洗衣机包括搅拌器 （波轮 400 为搅拌器的一种） 和内桶 500， 其洗涤方式为： 所述的搅拌器与内桶 500分别与齿轮减 速装置 200的动力输出端连接， 洗衣机通过离合机构 4进行洗涤和脱水工况的转换， 洗 涤工况时， 内桶 500固定不动， 搅拌器旋转， 脱水工况时， 搅拌器和内桶 500同向旋转。
如上所述， 当应用的洗衣机为滚筒式洗衣机时， 所述的滚筒式洗衣机包括滚筒 600 和内桶 500, 其洗涤方式为： 所述的滚筒 600与内桶 500分别与齿轮减速装置 200的动 力输出端连接，洗衣机通过离合机构进行洗涤和脱水工况的转换，洗涤工况时，滚筒 600 和内桶 500双向旋转， 脱水工况时， 滚筒 600和内桶 500同向旋转； 洗涤工况时， 所述 的内桶 500与滚筒 600随机根据阻力分配关系即时确定转速比， 并在转速比进行双向旋 转， 所述的转速比是可变化的。
同样如上所述， 当应用的洗衣机为滚筒式洗衣机时， 所述的滚筒式洗衣机包括滚筒 600和内桶 500， 其洗涤方式为： 所述的滚筒 600与内桶 500分别与齿轮减速装置 200 的动力输出端连接， 洗衣机通过离合机构进行洗涤和脱水工况的转换， 洗涤工况时， 内 桶 500固定不动， 滚筒 600旋转， 脱水工况时， 滚筒 600和内桶 500同向旋转。
当电磁离合机构断电后， 磁场消失， 在弹簧的弹力作用下， 离合齿圈 41 沿中间齿 轮 331轴向向下滑动， 使得离合齿圈 41与电机转子 23卡合， 由于离合齿圈 41与中间 齿轮 331之间不产生相对旋转， 所以此时中间齿轮 331以及与中间齿轮 331连接的脱水 轴 52和电机转子 23锁死， 从而导致齿轮减速装置 200自锁， 洗涤轴 51、齿轮减速装置 200、 脱水轴 52和电机转子 23同转速转动， 实现脱水功能。
所述的离合齿圈 41的具体结构说明参见本申请人的在先专利申请， 申请号为 CN201210084877. 4中关于离合齿圈的相关文字说明。
所述的定子安装盘 221和电机转子 23上分别设有与离合齿圈 41的上插齿和下插齿 固定卡合的上插槽部件 （图未示出） 和下插槽部件 （231b)。
这里还需要说明的是， 将电机定子 22直接与安装板 26固定连接时， 上述的电磁离 合机构与定子安装盘 21 的连接关系则全部替换为电磁离合机构与安装板 26 的连接关 系。
同时需要说明的是， 本发明所述的定子安装盘 221、 安装板 26、 以及上插槽等结构 也同样可以参见本申请人的在先专利申请， 申请号为 CN201210084877. 4的结构设计， 同样可以根据实际需要， 也可以在安装板 26上固定设置轴承壳体等。
本发明也可以根据安装结构需求， 所述的离合齿圈 41 也可以通过花键 （具体可以 脱水轴 52啮合且轴向滑动连接， 其与上述的离合 」 轮 331 的功能与效果实质上是完全相同的。
这里还需要说明的是， 也可以将离合机构 4设置在齿轮减速装置 200的其他传动件 与电机转子 23之间或直接设置在齿轮减速装置 200的传动件之间进行卡合或断开连接 来实现洗涤工况和脱水工况的转换； 离合机构 4的设置只要可以实现洗衣机洗涤工况和 脱水工况的转换即可。
由于在脱水工况时， 脱水轴 52要承受洗涤衣物的重量， 为了限制脱水轴 52的轴向 移动， 可以在脱水轴 52和中间齿轮 331之间设置平面轴承、 平垫和弹性挡圈 （图均未 示出）来限制脱水轴 52在其轴线方向的移动， 同时还可以在脱水轴 52不同位置上设置 承重卡簧或承重垫片实现对脱水轴 52的承重作用。
为了使洗涤轴 51和脱水轴 52在脱水工况时能够更稳定地转动， 在脱水轴 52和安 装板 26之间设置有第一轴承 831， 在脱水轴 52和定子安装盘 221之间设置有第二轴承 832。
进一步地， 在洗涤轴 51和脱水轴 52之间设置有第一水封 （图未示出）， 也叫小水 封， 在脱水轴 52和安装板 26之间设置有第二水封 60， 也叫大水封， 用于防止洗衣机工 作过程中洗涤水进入洗衣机驱动器内部。
以上具体实施方式所述的离合机构 4均为电磁离合机构， 当然地， 也可以是公知常 识中的机械离合机构， 相信本领域的技术人员在本发明基础上， 不需要花费创造性劳动 地将机械离合机构替代电磁离合机构。
由于上述实施方式所述的为实现各部件的连接、 承重、 轴向和径向限位、 密封作用 所用轴承、 卡簧、 垫片、 弹性挡圈、 平面轴承、 垫圈、 密封圈等结构均属于本领域技 术人员的常规设计手段， 本发明所述的实施方式可能存在对这些结构未能够做出完整 披露， 但相信这些是不具备新颖性和创造性的， 当然地， 具体设置也可以直接参见本 申请人的在先专利申请的文字描述， 申请号为 CN201210084877. 4。
同时以上实施方式所述的齿轮减速装置 200均为 NN型少齿差齿轮减速装置 200， 这可以使得本发明获得更大的传动比， 当然地， 根据实际需要所述的齿轮减速装置 200 还可以为 NGW齿轮减速装置 200， 具体可以为： 中间齿轮为内齿圈， 包括依次啮合的 中间齿轮、输入齿轮、输出齿轮，所述的中间齿轮可相对旋转地套装在所述的输出轴上， 输入齿轮为外齿轮并套装在输出齿轮轴上。本实施方式的其余相关结构可以参见其余任 意一种实施方式。

参见图 20， 一种洗衣机， 包括内桶 500、 搅拌器 700、 齿轮减速装置 200、 动力源 和离合机构 4， 其中： 所述的动力源为电机 100， 所述的齿轮减速装置 200的输出轴与 搅拌器 700固定连接， 所述的齿轮减速装置 200的输出轴套与内桶 500固定连接， 电机 100的转子作为动力源的旋转体与齿轮减速装置 200的动力输入端连接， 所述的离合机 构 4通过离与合状态切换实现齿轮减速装置 200的各部件之间的动力传动或锁定， 其余 相关部件可参见其他任意一种实施方式。 综上所述， 本发明所提供的一种洗衣机驱动机构包括： 用来产生转动动能的无转轴 旋转体 23 ; 安装在旋转体 23上的齿轮减速机构 200， 用于从旋转体 23偏心位置处获取 转动动能， 并对其进行减速或不减速处理； 连接齿轮减速机构的第一驱动部件 （例如， 图 1-12所示的输出轴 11 )，用来把经过减速或不减速处理的转动动能供应给洗衣机的相 应执行部件。 参见图 1-12及图 17-19。
上述的洗衣机相应执行部件可以是可执行洗涤和脱水作业的同一个执行部件如洗 衣机滚筒， 也可以是仅仅执行洗涤作业的波轮或搅拌器。
参见图 1-12， 本发明的齿轮减速机构 200包括： 安装在旋转体 23偏离轴心位置处 的输入齿轮轴 31，用来随着旋转体 23的旋转而围绕其轴心公转，从而获取其转动动能； 连接输入齿轮轴并相对于旋转体 23 自转的小直径输入齿轮； 以及与输入齿轮啮合连接 的大直径输出齿轮 332。
本发明的第一驱动部件是固定连接输出齿轮 332中心处的输出轴 11。
本发明的洗衣机驱动机构还包括专用于输出不减速转动动能的第二驱动部件， 该第 二驱动部件是套装在输出轴 11上并可轴向滑动的输出轴套 12。 第二驱动部件通常用于 需要采用两个执行部分分别进行洗涤和脱水的洗衣机， 对于这类洗衣机， 第一驱动部件 连接洗衣机的波轮或搅拌器， 第二驱动部件连接洗衣机内筒。
本发明的齿轮减速机构还包括： 位于所述旋转体 23之外并与所述输入齿轮啮合连 接的中间驱动齿轮 331， 该中间驱动齿轮 331的轴心固定连接所述输出轴套 12。 该中间 驱动齿轮 331至少具有两种功能。 功能之一是： 利用与其啮合连接的离合装置 4对旋转 体 23的卡合作用， 使输出轴套 12按旋转体 23的旋转速度驱动洗衣机内筒旋转； 功能 之二是： 当与其啮合连接的离合装置 4脱离旋转体 23时， 使输入齿轮相对于旋转体 23 进行自转。 也就是说， 中间驱动齿轮可以在输入齿轮随着输入齿轮轴 31进行公转而公 转的同时， 迫使输入齿轮相对于旋转体 23进行自转。
参见图 1-12， 旋转体 23轴心处开设有用来安装输出轴 11的轴心通孔， 输出轴 11 可旋转地安装于旋转体 23的轴心通孔中。
参见图 1、 图 3和图 4、 图 5、 图 8和图 9所示的实施例， 旋转体 23偏离轴心的位 置处设有用来安装输入齿轮轴 31的偏心通孔，输入齿轮轴 31可旋转地安装于偏心通孔 中， 并且其两端分别伸出偏心通孔。 在这些实施例中， 输入齿轮包括： 固定连接输入齿 轮轴 31—端的第一输入齿轮 321 ; 以及固定连接输入齿轮轴 31另一端的第二输入齿轮 322 , 该第二输入齿轮 322与输出齿轮 332啮合连接。
参见图 1、 图 3和图 4、 图 5、 图 8和图 9所示的实施例， 中间驱动齿轮是一个与第 一输入齿轮 321啮合连接并套装在输出轴套 12上的中间齿轮 331。其工作原理是，通过 离合装置 4的轴向滑动， 使中间齿轮 331处于不围绕旋转体轴心公转的状态， 从而使围 绕旋转体轴心公转的第一输入齿轮 321进行自转， 并进而带动输入齿轮轴 31和第二输 入齿轮 322进行自转。
更具体地说， 由于中间齿轮 331不进行公转，而第一输入齿轮 321在输入齿轮轴 31 驱动下围绕旋转体轴心公转， 因此在啮合连接的中间齿轮 331与第一输入齿轮 321之间 产生了相互作用力， 从而促使第一输入齿轮 321相对于旋转体自转， 并进而带动输入齿 轮轴 31和第二输入齿轮 322进行自转。
参见图 2、图 6和图 7所示的实施例，本发明的输入齿轮轴 31—端还可以固定连接 旋转体 23偏离轴心的位置处。此时，输入齿轮包括固定连接在一起的第一输入齿轮 ( 321 ) 和第二输入齿轮 （322)， 该第一输入齿轮 （321 ) 和第二输入齿轮 （322 ) 可以是双联齿 轮。
此外， 如图 2、 图 6和图 7所示， 第一输入齿轮 321和第二输入齿轮 322的轴心分 别与输入齿轮轴 31另一端转动连接； 第二输入齿轮 322与输出齿轮 332啮合连接。
如图 1-12所示， 本发明的齿轮减速机构还包括与所述中间齿轮 311啮合连接的离 合装置 4， 当离合装置 4轴向滑动卡合旋转体 23时， 使输出轴套 12在中间齿轮 311驱 动下， 按旋转体 23的旋转速度进行旋转。
在图 2、 图 6和图 7所示的实施例中， 中间驱动齿轮是一个与第一输入齿轮 321啮 合连接并套装在输出轴套 12上的中间齿轮 331。
如上所述， 通过离合装置 4的轴向滑动， 可以使中间齿轮 331处于不围绕旋转体轴 心公转的状态， 从而使围绕旋转体轴心公转的第一输入齿轮 321进行自转， 进而带动第 二输入齿轮 322进行自转。
另一方面， 在图 2、 图 6和图 7所示的实施例中， 输入齿轮轴 31—端转动连接旋转 体偏离轴心的位置处。 此时， 输入齿轮包括与输入齿轮轴 31 另一端固定连接的具有第 一输入齿轮 321和第二输入齿轮 322的双联齿轮；并且第二输入齿轮 322与输出齿轮 332 啮合连接。第一输入齿轮 321啮合连接并套装在输出轴套 12上的中间齿轮 331， 以便第 一输入齿轮第一输入齿轮 321通过与中间齿轮相互作用进行自转。
如上所述， 通过离合装置 4的轴向滑动， 使中间齿轮 331处于不围绕旋转体轴心公 转的状态， 从而使围绕旋转体轴心公转的第一输入齿轮 321进行自转， 进而带动第二输 入齿轮 322和输入齿轮轴 31进行自转。
在本发明中， 中间齿轮 311啮合连接离合装置 4， 离合装置 4可以轴向滑动地套装 , ^ 在输出轴套 12上， 通过轴向滑动使离合装置 4卡合旋转体 23或脱离与腚转体 23的卡 合
具体地说， 本发明可以通过推动与中间齿轮 3 U啮合连接的离合装置 4的离合齿圈 41正方向轴向滑动，使离合装置 4的离合齿圈 41脱离与旋转体 23的卡合，从而使中间 齿轮 331进入不围绕旋转体轴心公转的状态，以便低速输出旋转体转动动能。也就是说， 当离合装置 4的离合齿圈 41脱离旋转体 23时， 中间齿轮 311因脱离旋转体 23而进入 不围绕旋转体 23轴心公转的状态， 导致第一输入齿轮得以自转， 进而带动第二齿轮自 转， 从而使输出轴 1 1实现了旋转体转动动能的低速输出。
本发明还可以通过推动与中间齿轮 311啮合连接离合齿圈 41反方向轴向滑动， 迫 使离合装置 4离合齿圈 41卡合旋转体 23， 从而使中间齿轮 331进入围绕旋转体轴心公 转的状态， 以便高速输出旋转体转动动能。 也就是说， 当离合装置 4卡合旋转体 23时， 造成中间齿轮 311与旋转体 23结合在一起， 迫使中间齿轮 311进入围绕旋转体 23轴心 公 ^转的状态， 使中间齿轮 311失去对第一输入齿轮 321进行自转的作用力， 导致第一输 出齿轮和第二输入齿轮均停止自转， 从而使输出轴 11 实现了旋转体转动动能的高速输 出。
以上对本发明进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式 进行了阐述， 以上实施方式的说明只是用于帮助理解本发明的方法及其核心思想。 应当 指出， 对于本技术领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以对 本发明进行若干改进和修饰， 这些改进和修饰也落入本发明权利要求的保护范围内。
