下面，通过本发明的实施例，参照用于说明榨汁机和搅拌机兼容动力装置的附图来说明本发明。
图1是根据本发明的一实施例的榨汁机和搅拌机兼容动力装置的立体图，图2是图1的分解立体图，图3是图1的剖视图，图4是第二驱动轴的剖视图，图5是支撑部的剖视图。
如图1至图3所示，根据本发明的一实施例的榨汁机和搅拌机兼容动力装置100可包括驱动部、第一驱动轴150、第二驱动轴160、支撑部110、第一轴承171及第二轴承172而构成。而且，可进一步包括第三轴承173。
驱动部是为了使第一驱动轴150和第二驱动轴160旋转而产生并传递动力的结构要素的组合，可包括马达120、离合器轴承125和减速部而构成。
马达120用于高速旋转第一驱动轴150。此时，第一驱动轴150可以是马达120的马达轴或者向马达120的马达轴的长度方向延伸结合的另一轴形态。第一驱动轴150的端部形成为向支撑部110的上面外部突出。
向第一驱动轴150的端部可结合搅拌刀片（未图示）。此时，将第一驱动轴150的端部形成为角形轴或者形成为如图所示在第一驱动轴150的表面上具有重复的突出部和凹槽部的形态，并用与此对应的形状在搅拌刀片的轴上形成中空轴，由此强化搅拌刀片和第一驱动轴150之间的结合力。与此相反，还可以将第一驱动轴150的端部形成为中空轴，将搅拌刀片的轴插入第一驱动轴150的中空的方法向第一驱动轴150结合搅拌刀片。由此，可向高速旋转的第一驱动轴150的端部结合搅拌刀片，以能够高速旋转搅拌刀片292。
此时，马达120优选使用无刷电机（BLDC马达），其可向一方向及另一方向控制旋转方向，并去除马达120内部容易磨损的刷子而提高耐久性，且不影响高速旋转，但并不限定于此。
离合器轴承125可安装在向马达120的上部延伸的第一驱动轴150上。离合器轴承125是仅向一个方向传递动力的轴承，当插入其中间的第一驱动轴150向一方向（例如，逆时针方向）旋转时其锁定（lock）被解除，使得第一驱动轴150能够自由旋转，而向另一方向（例如，顺时针方向）旋转时则其被锁定（locking），从而能够将第一驱动轴150的驱动力传递给结合于离合器轴承125的外轮的动力传递部127。如图所示，所述动力传递部127套设在离合器轴承125的外部侧面，并在动力传递部127的上面可形成有供第一太阳齿轮131插入的中空128。
在第一驱动轴150的上端部可形成有第二驱动轴160，在第二驱动轴160上形成有贯通孔169，第一驱动轴150穿过该贯通孔169的内部。即，第二驱动轴160和第一驱动轴150以同心圆上的双轴形态形成，且第二驱动轴160围绕第一驱动轴150的端部外侧。第二驱动轴160的上端部上形成有以角形突出的角形突出部165，以能够插入及结合于形成在螺杆（未图示）的旋转轴上的角形轴孔中，第二驱动轴160的下端部位于支撑部110内。即，第二驱动轴160的端部也形成为向支撑部110的上面突出。
支撑部110在中央形成有孔，如上所述，通过孔突出双轴形态的第一驱动轴150和第二驱动轴160的上端部，并且能够旋转地支撑第二驱动轴160。在支撑部110中央的孔周围形成有多个螺孔119，环齿轮145在所述螺孔119的对应位置上也形成有上下贯穿的螺孔146，可向螺孔119、146中插入螺丝来固定环齿轮145及支撑部110。
此时，第一驱动轴150的外侧面和第二驱动轴160的内侧面之间可配设第一轴承171，第二驱动轴160的外侧面和支撑部110的内侧面之间可配设第二轴承172。因此，所述第二驱动轴160对于支撑部110与第一驱动轴150能够进行相对旋转。
此时，在本实施例中，第一轴承171和第二轴承172没有配设在上下方向的不同高度上，而是配设在水平方向的相同位置上或者相互重叠的位置上。即，将第一轴承171设置于第二轴承172的内侧，以缩短整个轴的长度，由此能够更加紧凑地构成整个动力装置。
而且，在第二轴承172的上部位置，在第二驱动轴160和支撑部110之间可配设第三轴承173。因此，本发明在第二驱动轴160和支撑部110之间配设有二级轴承172、173，在第一驱动轴150和第二驱动轴160之间配设有单个轴承171，由此在第一驱动轴150、第二驱动轴160及支撑部110之间总共可配设三个轴承171、172、173。
在第二驱动轴160的底面的中央，在第一驱动轴150插入的贯通孔169的周围形成有直径大于贯通孔169直径且挖成圆形的第一轴承插入槽162。因此，通过第一轴承插入槽162，可在第一驱动轴150与第二驱动轴160之间配设第一轴承171。
而且，第二驱动轴160在下端部形成有直径较大且在外侧面上配设有第二轴承172的凸缘状的下部凸缘部161，在下部凸缘部161的上部形成有直径比下部凸缘部161小且在外侧面上配设有第三轴承173的中间轴部163，且在中间轴部163的上部形成有角形突出部165。
此时，在支承部110的底面中央部可形成有以圆形状凹陷的第二轴承插入槽112，在所述第二轴承插入槽112的内侧面和第二驱动轴160的外侧面之间的隔开空间中可配设第二轴承172。此时，如前所述，第一轴承171位于第二轴承172的内侧。
此外，在所述中间轴部163的外侧面上配设有第三轴承173，在第二轴承插入槽112的上部形成有直径小于第二轴承插入槽112的直径且以圆形状凹陷的第三轴承插入槽114，以便能够配设第三轴承173。因此，在所述第三轴承插入槽114的内侧面和中间轴部163的外侧面之间的隔开空间中可配设第三轴承173，此时第三轴承173可配设在下部凸缘部161的上表面。
上述的第二驱动轴160与离合器轴承125之间可形成有通过减速马达120的旋转速度来低速旋转第二驱动轴160的减速部。
减速部可包括太阳齿轮131、136、141、行星齿轮133、138、143及环齿圈145而构成。
如图3所示，第一太阳齿轮131套设于第一驱动轴150，第一太阳齿轮131的下端部插入动力传递部127的中空128中，从而第一太阳齿轮131与动力传递部127一起在第一驱动轴150上进行旋转。此时，在第一太阳齿轮131的上端部外侧面上沿圆周方向形成有齿轮，在所述第一太阳齿轮131的齿轮上沿第一太阳齿轮131的周围啮合有多个第一行星齿轮133（附图中形成有三个行星齿轮）。
而且，围绕多个第一行星齿轮133的外侧，形成有与多个第一行星齿轮133啮合的环齿轮145。此时，如上所述，环齿轮145与支撑部102一起被螺丝149固定而定位。
因此，所述多个第一行星齿轮133分别与环齿轮145及第一太阳齿轮131啮合，并且在第一太阳齿轮131旋转时，多个第一行星齿轮133在环齿轮145与第一太阳齿轮131之间以第一太阳齿轮131为中心进行自转及公转。
此时，如图所示，太阳齿轮131、136、141及多个行星齿轮133、138、143可形成为多级结构，在第一太阳齿轮131和多个第一行星齿轮133的上部可形成有第二太阳齿轮136和多个第二行星齿轮138，在第二太阳齿轮136和多个第二行星齿轮138的上部可形成有第三太阳齿轮141和多个第三行星齿轮143。此时，在各级之间可形成有载体147，载体147用于支撑位于下方的行星齿轮133、138的轴，并与所述行星齿轮133、138的公转一起旋转，且将位于上部的太阳齿轮136、141结合到中央以传递旋转力。
此时，位于最上端的第三行星齿轮143的轴可插入并支撑于上述第二驱动轴160的下部凸缘部161。由此，随着多个行星齿轮133、138、143进行自转运动的同时进行公转运动，上部的第二驱动轴160经过多级减速，以低速进行旋转运动。
在本实施例中，以太阳齿轮131、136、141及多个行星齿轮133、138、143构成为三级且以多级方式减速马达120的旋转速度为例进行了说明，但并不一定限于此，还可以构成为一级或二级。进一步，还可以构成为三级以上。
下面说明根据本实施例高速及低速旋转第一驱动轴150及第二驱动轴160的驱动部的运行。
图6图示用作搅拌机时的图3的运行，图6图示用作榨汁机时的图3的运行。
如图6所示，若向逆时针方向高速旋转马达120，则安装在第一驱动轴150上的离合器轴承125的锁定被解除，第一驱动轴150能够与马达120的旋转一起高速旋转。因此，在向第一驱动轴150的端部结合搅拌机的搅拌刀片时，可用作搅拌刀片高速旋转的搅拌机。
此时，在第一驱动轴150高速旋转时，由于可通过离合器轴承125切断动力传递，因此减速部与第二驱动轴160不会运行。由此，能够切断低速驱动第二驱动轴160的减速部的不必要的运行，能够减少动力损失、噪音、磨损、故障等问题。
然后，如图7所示，若将马达120向顺时针方向高速旋转，离合器轴承125则被锁定，向结合于离合器轴承125的外轮的动力传递部127传递动力，通过结合于所述动力传递部127的太阳齿轮131、多个行星齿轮133、环齿轮145的啮合，所述多个行星齿轮133自转的同时低速进行公转运动。此时，如上所述，太阳齿轮131、136、141和多个行星齿轮133、138、143可形成为多级。此时，与多个行星齿轮143的上部轴结合的第二驱动轴160随着多个行星齿轮131、136、143的公转运动减速，由第一轴承171、第二轴承172及第三轴承173被支撑在支撑部102与第一驱动轴150之间并进行低速旋转。因此，可将螺杆300的下部旋转轴结合到第二驱动轴160的端部来用作榨汁机，该榨汁机的螺杆300进行低速旋转。
本发明并不限于上述实施例，而是在权利要求书的范围内可由多种形式的实施例实现。因此在不脱离权利要求书所要求保护的本发明精神的范围内，本领域技术人员所能进行的各种变更均属于本发明的保护范围之内。
