Description

一种高转速电机的储油机构和高转速电机
本申请要求于2021年11月30日申请的、申请号为202111442385.3的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及轴承润滑技术领域，具体地涉及一种高转速电机的储油机构和高转速电机。
 背景技术
随着新能源汽车的飞速发展，市场对电动系统的转速要求越来越高，目前主流的电机转速已高达16000RPM,而在研发高转速电机的转速将会到20000RPM转速以上。随着转速的提高，对轴承的润滑冷却提出更高的要求，相比较传统的脂润滑方案。对于高转速电机轴承需要设计专门的油道，进行润滑冷却。但是从油泵启动到油液淋入轴承这段时间，若驾驶者立刻启动汽车，这时电机轴承在未润滑冷却的情况下，进行高速干磨转动，对轴承会造成严重损失，降低电机的寿命。
现有的油冷电机的轴承冷却，一般仅设计轴承油道或者在轴承上方设计集油结构，使得轴承在油液充足的情况下，可以得到润滑冷却。但是在电机启动的瞬间，冷却油液并没有到达轴承室处，就会造成轴承干摩擦，尤其在高转速时，很容易导致轴承干磨，导致轴承滚道损耗，降低电驱动寿命。
 技术问题
本申请实施例的目的是提供一种高转速电机的储油机构和高转速电机，通过特别设计的挡板和轴承室密封配合，使得油液可以积累在轴承室中，待电机再启动时可以保证轴承处在润滑的情况下，避免轴承干磨损害。

本发明的实施方式
以下结合附图对本申请实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请实施例，并不用于限制本申请实施例。
图1是根据本申请的一个实施方式的一种高转速电机的储油机构的剖视图。图2是根据本申请的一个实施方式的一种高转速电机的储油机构的前轴承挡油板正视图。图3是根据本申请的一个实施方式的一种高转速电机的储油机构的前轴承挡油板和后轴承挡油板的示意图。该储油机构可以包括：减速器前半壳1、电机2、前轴承挡油板3。减速器前半壳可以包括：孔洞10和第一轴承室11。电机2可以包括第一轴承20。该减速器前半壳1可以卡接在电机2的前端，并且该减速器前半壳1内部可以设置有用于供电机2的转子穿过的孔洞10。在孔洞10远离电机2的一端的可以向内凹陷以形成可以容纳电机2的第一轴承20的第一轴承室11。在第一轴承室11的底部可以设有前轴承挡油板3。该前轴承挡油板3可以与第一轴承室11的底部形成第一储油槽30。该第一轴承20可以在第一储油槽30侧面，在第一储油槽30积累冷却油液后，即使电机驱动停止工作，该第一储油槽30也能积累一定的油量，可以使得第一轴承20一直浸润在冷却油液中，在电机驱动再次开始工作时，可以避免第一轴承20干磨损害。
在本申请的一个实施方式中，如图1所示，该电机2还可以包括第二轴承21。在孔洞10靠近电机2的一端可以向内凹陷以形成用于容纳第二轴承21的第二轴承室12。第二轴承21设置在第二轴承室12内，且第二轴承室12与第一轴承室11连通。该前轴承挡油板3的高度可以高于第二轴承21的至少一部分，在前轴承挡油板3与第一轴承室11形成的第一储油槽30积累油液后，因为第二轴承室12与第一轴承室11连通，又因为前轴承挡油板3高度高于第二轴承21的至少一部分，第一储油槽30积累的冷却油液可以浸润到第二轴承21，使得该第二轴承21一直处于润滑中，避免第二轴承21在电机驱动再次工作时发生干磨损害现象。
在本申请的一个实施方式中，如图1所示，该电机2还可以包括置于后端的第三轴承22。该储油机构还可以包括后端盖4和后轴承挡油板5。该后端盖4可以设有用于容纳电机2的转子和第三轴承22转动的圆孔40。在该后端盖4与电机2连接时，后端盖4的圆孔40套在电机2的转子上。该后轴承挡油板5可以设置在圆孔40的底部，从而可以与圆孔40的底部形成第二储油槽50。第三轴承22可以设置在第二储油槽50的侧面且与第二储油槽50连通。在电机驱动开始工作时，第二储油槽50可以储存一定的冷却油液，然后第三轴承22可以浸润在第二储油槽50积累的冷却油液中，使得第三轴承22可以一直处在润滑中。在电机驱动再次工作时，因为第三轴承22一直处于润滑的状态，则第三轴承22不会因为初始启动时油液未到达该第三轴承22而发生干磨现象。
在本申请的一个实施方式中，如图3所示，该后轴承挡油板5可以是圆环形，且与圆孔40的同轴心连接。该后轴承挡油板5的内圆略大于第三轴承22的尺寸，因此，在该后轴承挡油板5与圆孔40形成的第二储油槽50积累冷却油液时，冷却油液的油液面会高于第三轴承22的底部。综上所述，该后轴承挡油板5既不影响电机2的转动，又能够使得第三轴承22可以一直浸润在后轴承挡油板5与圆孔40形成能的第二储油槽50积累的冷却油液中，避免第三轴承22因为缺乏润滑而发生干磨的现象。
在本申请的一个实施方式中，如图1所示，该储油机构还可以包括电机壳体6。该电机壳体6可以设置在电机2的主体的外围，并且在电机壳体6的顶部可以设置有第一注油孔60。在电机2开始工作时，冷却油液可以通过第一注油孔60注入该电机2中。
在本申请的一个实施方式中，如图1和图5所示，该减速器前半壳1可以与电机壳体6连接。该减速器前半壳1可以包括第二注油孔13和前轴承室集油口14。第二注油孔13可以设置在减速器前半壳1和电机壳体6的连接处，并且通过电机壳体6内的油路和第一注油孔60连接。前轴承室集油口14可以设置在第二轴承室12的顶部附近，且该前轴承集油口14的下方为第二轴承21。在需要对该电机2注入冷却油液时，冷却油液可以从第一注油孔60进入，然后通过电机壳体6内的油路流到第二注油孔13处，从第二注油孔13通过减速器前半壳1内部的油路流到前轴承室集油口14，最后流到第二轴承21处，并对该第二轴承21进行润滑。在流过第二轴承21后，因为第二轴承室12与第一轴承室11连通，则冷却油液也会流到第一轴承室11进而对第一轴承20进行润滑并且部分冷却油液会积累在第一储油槽30内。在冷却油液从第二注油孔13流到前轴承室集油口14时，冷却油液从第二注油孔13随着重力落下，落到第二轴承室12顶部，第二轴承室12的顶部具有一定斜度，则第二轴承室12的顶部可以有斜面，前轴承室集油口14在第二轴承室12的顶部的斜面的下方，冷却油液会顺着斜面向下流动，从前轴承室集油口14流到第二轴承21并对其进行润滑。
在本申请的一个实施方式中，如图1和图4所示，后端盖4可以包括第三注油孔41和后轴承淋油孔42。第三注油孔41可以设置在后端盖4与电机壳体6的连接处，然后通过设置在电机壳体6内的油路与第一注油孔60连接。后轴承淋油孔42可以设置在圆孔40的顶部附近，并且该后轴承淋油孔42可以通过设置在后端盖4内部的油路与第三注油孔41连接。第三轴承22可以设置在后轴承淋油孔42的下方，在第一注油孔60注入冷却油液后，顺着电机壳体6内的油路流到第三注油孔41处，然后顺着后端盖4内部的油路流到后轴承淋油孔42处，进而可以流到第三轴承22上对其进行润滑并且在第二储油槽50内积累一定的冷却油液使得第三轴承22一直处于润滑状态。
在本申请的一个实施方式中，如图3所示，该前轴承挡油板3可以为半圆形，且半圆形的弧形部分与第一轴承室11的底部连接，且该半圆形的直线部分的高度高于第一轴承20的轴线宽度，挡油板3采用半圆形结构相较于现有传统的环形结构，匹配性更好，节省材料，降低成本，同时可采用塑料件，成本更低。在前轴承挡油板3与第一轴承室11形成储油槽30后，因为该前轴承挡油板3的直线部分的高度高于第一轴承20的轴线宽度，则该储油槽30积累的冷却油液的液面的高度也会高于第一轴承20的轴线宽度，则该第一轴承20可以浸润在冷却油液里。
在本申请的一个实施方式中，如图1所示，前轴承挡油板3可以通过螺栓7与第一轴承室11连接，使得该前轴承挡油板3可以作为第一轴承20的压板，固定第一轴承20。后轴承挡油板5可以通过螺栓7与后端盖4连接，且该后轴承挡油板5可以作为第三轴承22的压板，固定第三轴承22，使得该储油机构整体结构更加紧凑。
另一方面，本申请还提供一种高转速电机，包括如上述任一所述的储油机构和电机2。
通过上述技术方案，本申请提供的一种高转速电机的储油机构和高转速电机通过将减速器前半壳卡接于电机的前端，在减速器前半壳有用于容纳电机的第一轴承的第一轴承室。前轴承挡油板的弧形部分与第一轴承室的底部连接形成第一储油槽，使得冷却油液可以在该第一储油槽内积累，待电机再启动时可以保证轴承处在润滑的情况下，从而避免轴承干磨损害。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括要素的过程、方法、商品或者设备中还存在另外的相同要素。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
