技术领域
本申请涉及齿轮箱润滑技术领域，例如涉及一种齿轮箱。
背景技术
齿轮箱是机械传动中广泛应用的重要部件，齿轮是齿轮箱传动中的基础零件。为了降低齿轮啮合过程中产生的摩擦，常需要采用齿轮润滑油对齿轮进行润滑。但是在齿轮润滑过程中常出现液位较低导致的飞溅润滑油量不足的情况，为了提高飞溅润滑油的油量，相关技术中一般在齿轮箱内设置刮油板或者刮油块，但是刮油板或者刮油块所能够供用的油量非常有限，且对装配精度要求很高。除了设置刮油板或者刮油块外，还可以在齿轮箱的内腔铸造或者机加工集油槽，利用集油槽收集飞溅的润滑油，但是集油槽增大了齿轮箱的铸造难度或者机加工难度，且飞溅润滑油的油量也很有限。
为了增加飞溅润滑油油量，需要提高齿轮箱的油位，但是油位过高又会增加齿轮箱的搅油损失以及降低齿轮箱的传动效率，此外，还会增加齿轮箱机械密封处的漏油风险。
因此，如何在不提高齿轮箱的油位的前提下，增加飞溅润滑油的油量是现在亟需解决的技术问题。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本申请的技术方案。
本实施例提供了一种齿轮箱，如图1和图2所示，该齿轮箱包括箱体(图中未示出)、设置在箱体内行星轮系机构，行星轮系机构具体包括行星架200、多个行星轮300、太阳轮(图中未示出)以及齿圈(图中未示出)，箱体的底部设置有润滑油池，行星轮300安装在行星架200上，太阳轮位于多个行星轮300中间，且多个行星轮300位于齿圈内，并与外周的齿圈啮合，多个行星轮300同时与内周的太阳轮啮合。
行星架200的顶部设置有允许驱动轴400通过的通孔，且通孔的内壁上设置有轮齿结构，驱动轴400伸入通孔的一端也设置有轮齿结构，驱动轴400上的轮齿结构与行星架200上的轮齿结构相互啮合。当驱动轴400在动力源的驱动下转动时，行星架200即能够随之发生转动。
齿轮箱还包括润滑油池(图中未示出)和搅油盒100，润滑油池设置于所述齿轮箱内底部，搅油盒100安装在行星架200的外侧壁上，搅油盒100包括储油腔，储油腔具有挖油口1和出油口2，当驱动轴400驱动行星架200转动时，位于行星架200侧壁上的搅油盒100也能够随之发生转动，从而浸入齿轮箱的润滑油池。当搅油盒100浸入齿轮箱的润滑油池内后，润滑油池内的润滑油能够通过挖油口1进入储油腔内暂存，当搅油盒100随着行星架200继续旋转时，搅油盒100能够到达远离润滑油池的较高位置，待到达润滑点时，润滑油能够从出油口2流出至润滑点处，从而实现对润滑点的润滑。通过在齿轮箱的行星架200上设置搅油盒100，能够在润滑油池油位较低时实现对齿轮箱的一个或多个润滑点的有效润滑，避免润滑不足导致的机械磨损，有利于提高齿轮箱的使用寿命和传动稳定性。
如图3和图4所示，该搅油盒100包括第一盖板3、第二盖板4以及多个侧板，第一盖板3和第二盖板4相对设置。第一盖板3为与行星架200固定连接的弧形板，为了便于将第一盖板3固定在行星架200上，将第一盖板3的长度增大，并突出侧板设置，并在突出侧板的端部设置连接孔8，利用连接件穿过连接孔8将搅油盒100固定在行星架200上，当然除了连接件连接以外，还可以 采用其他连接方式。
侧板位于第一盖板3和第二盖板4之间，且每个侧板的一端与第一盖板3连接，每个侧板的另一端与第二盖板4连接，第一盖板3、第二盖板4以及多个侧板围设形成上述储油腔。挖油口1和出油口2的位置不做具体限定，例如可以设置在第二盖板4上，也可以设置在侧板上，只要能够保证顺利将润滑油储存至储油腔并顺利将润滑油运输至润滑点即可。在本实施例中，为了提高进入储油腔内的润滑油量，以及为了避免润滑油过早从出油口2流完，将挖油口1和出油口2设置在不同的侧板上，挖油口1的开口方向朝向行星架200的旋转方向设置，出油口2的开口方向与挖油口1的开口方向不同。
侧板的个数根据第一盖板3和第二盖板4的边长数决定，例如可以为三个、四个、五个或者更多个；侧板的形状根据第一盖板3和第二盖板4的形状决定，例如可以为三角形、梯形、方形或者其他形状。在其他实施例中，多个侧板也可以由一块板弯折而成。在本实施例中，由于第一盖板3和第二盖板4均为长方体，因此侧板的数量为四个，分别为前侧板5、左侧板6、后侧板7和右侧板，前侧板5和后侧板7相对设置，左侧板6和右侧板相对设置，在行星架200旋转时，前侧板5设置在搅油盒100的前面，后侧板7为搅油盒100的后面。定义图3和图4中的左侧为前面，右侧为后面。挖油口1位于前侧板5上，出油口2位于左侧板6上，将挖油口1设置于前侧板5上，便于润滑油进入储油腔，将出油口2设置于左侧板6上，能够避免润滑油从挖油口1进入储油腔后直接从出油口2流出。当然除了左侧板6以外，还可以将出油口2设置在右侧板上。出油口2的开口面积小于挖油口1的开口面积，从而能够延长润滑油的流出所需的时间。
为了降低搅油盒100在经过润滑油池时受到的阻力，降低搅油盒100在润滑油中运动时的效率损失，将前侧板5朝后侧板7的方向倾斜设置，如图3和图4所示，前侧板5与第一盖板3之间呈锐角设置，前侧板5与第二盖板4之间呈钝角设置。后侧板7与第一盖板3之间呈锐角设置，左侧板6与第二盖板4之间呈钝角设置。
由于搅油盒100旋转至润滑油池处时，第二盖板4与润滑油池的距离最近，因此在本实施例中，将挖油口1设置在前侧板5靠近第二盖板4的一端，从而提高进入储油腔内的润滑油量。并将挖油口1的开口面积设置为小于前侧板5的面积，该种设置还能够保证搅油盒100旋转至远离润滑油池的最高点时，润滑油能够储蓄至储油腔内挖油口1的下方，从而避免润滑油从挖油口1内流出。将出油口2设置在左侧板6靠近第一盖板3的一端，从而加大出油口2与挖油口1之间的距离，避免润滑油过早从出油口2内流出。
为了对多个润滑点进行同时润滑，出油口2的数量可以设置为多个，在本实施例中，如图3和图4所示，出油口2的数量为两个，其中一个出油口2位于左侧板6的一端，另一个出油口2位于左侧板6的另一端。如图2所示，当行星架沿逆时针方向旋转时，搅油盒100在远离润滑油池至到达最高点前，主要由靠近前侧板5一端的出油口2将润滑油放出；搅油盒100由最高点接近润滑油池时，主要由靠近后侧板7一端的出油口将润滑油放出。且为了将润滑油精确引至润滑点处，提高润滑效果，还可以在出油口2上设置导油结构，导油结构的一端与出油口2连通，另一端与润滑点连通，具体地，导油结构可以为导油管或者导油槽等结构。当然在其他实施例中，出油口2的数量还可以根据实际需求具体设定。
为了进一步提高润滑效果，在本实施例中，搅油盒100的数量为多个，多个搅油盒100沿行星架200的周向分布，可选均匀分布。搅油盒100上挖油口1的开口方向和开口位置可以相同，也可以不同，当行星架200仅沿一个方向旋转时，也就是仅正转或者仅反转时，可选为相同；而当行星架200既需要正转又需要反转时，可选为不同。
