本发明涉及一种液压能向机械能转换的摆线液压马达，尤其是具有高承压能力以及小型安装尺寸的摆线液压马达，属于液压传动技术领域。
摆线液压马达是一种低速大扭矩马达，具有体积小、单位功率密度大、效率高、转速范围宽等优点，因而得到了广泛应用，随着工农业发展水平提高应用将更加广泛。
摆线液压马达的主要有轴配流和平面配流，轴配流马达由于轴径与孔径的孔道配合间隙运动的轴向配流特点，其各结合面均为平面，直接采用O型圈进行平面密封；而平面配流由于不同径向平面孔道相互配流特点，尤其是对于8/9齿转定子副的径向尺寸大，排量系数大，为了保证截面尺寸较小，而将马达结构设计紧凑性将配流支撑板嵌入在后盖内，采用单个O型圈进行两个垂直方向的双面密封。
据申请人了解，现有的大量平面配流马达采用配流支撑板嵌入在后盖内，应用单个O型圈进行两个垂直方向的双面密封，如文件CN 2911341Y文件所述的O型密封圈定位密封装置，在市场的推广应用中获得十分成功的效用，但其对O型密封圈的本身质量苛刻要求很高，尤其在应用工况条件十分恶劣时，如温度高、转速高、背压高、工作压差大，少部分还是有可能性会发生结合面有油迹现象几率，严重情况在较长时间使用会有形成滴油不良现象，该种结构马达的核心零件主要为8/9齿转定子副，转定子副为四方形结构，为大中型结构摆线马达，如申请人的BMT型号摆线液压马达，其最高连续压力低于21MPa。
为了适应应用领域的发展变化，不断提高大中型结构液压马达的高工作压差、高输出扭矩、高可靠性逐渐成为日益重要的研究课题。然而，现有大中型结构摆线马达由于结构的局限性，不能够很好地满足高端市场以及30MPa左右的柱塞泵系统的直接驱动应用而节约能源，尤其是无法满足小连接尺寸的要求。

为了使本发明的目的、技术方案及优点更加清楚明白，以下通过实施例，并结合附图，对本发明的摆线液压马达进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
本发明一种摆线液压马达基本结构见图1和图2所示，在本发明中，摆线液压马达包括体壳10，安置在体壳10内的扭矩输出的输出轴11，以及与体壳10采用螺栓固连的连接转定子副13、配流系统14和油液进出马达内腔的后盖15。本发明通过对摆线液压马达整体结构研究，尤其是大中型结构摆线液压马达，使得摆线液压马达整体结构紧凑，运动平稳可靠，而且，还能保证马达接合面密封质量的可靠，并对输出轴11受力结构创新，以提高摆线液压马达的承压能力，保证密封可靠。
参见图1至图3，进一步地，摆线液压马达的基本结构采用的一种基于8/9齿的摆线液压马达镶柱式转定子副13，所述摆线转定子副13具有较大截面尺寸，如四方外形尺寸为124×124，使得扭矩传递机构可以设置具有足够的扭矩输出能力，由于本发明的针对为高压力级马达，马达需要输出更高的扭矩，而摆线液压马达由于转子13偏心运动，其结构已很紧凑，采用8/9齿的较大截面结构可以使得扭矩输出零件可以粗到足够承受大扭矩。再进一步地，转定子副13包括定子131、针齿132和转子133。
本发明提供一种具有小型安装尺寸高压的摆线液压马达，从而通过端面密封结构的创新，保证马达接合面密封质量的可靠，通过对马达小安装尺寸及其输出轴承力结构与轴承的创新，
提升马达安装适应性与承受力的可靠性，通过马达结构强度的增强，提升马达的本体零件的强度。
参见图1，可选地，体壳10具有安装固定法兰面体壳10具有止口连接尺寸，体壳10还具有安装定位止口圆面，体壳10后端设置了连接板16，体壳10前端内孔设置了旋转轴封17，体壳10内腔前后设置支撑输出轴11的两个支撑轴承。进一步地，止口连接尺寸为SAE A型标准的Φ82.55或相近尺寸止口连接尺寸。这样能够使得摆线液压马达具有承受高压力的能力，更高的可靠性，马达的受力结构简单可靠，尤其是具有SAE A型标准的Φ82.55或相近尺寸止口马达连接尺寸的一种结构，具有更加广泛的应用适应性。
本发明还提供一种高压力平面配流的摆线液压马达，从而通过端面密封结构的创新，以及防止结合面的相对转动位移，保证马达接合面密封质量的可靠，通过对马达输出轴受力结构的创新，提升马达轴承安装与承受力的可靠性。
参见图2，又可选地，体壳10具有安装定位止口，配流系统14的配流支撑板141外形与转定子副13的定子131外形相同，配流支撑板141两端面外露，配流支撑板141一端面与定子131端面相连，另一端面与后盖15端面相连，两接触面采用O型圈进行平面密封，定子131、配流支撑板141和后盖15的两个接触面采用两个限位销21进行限位。
下面对摆线液压马达的具体结构详述：
参见图1、图5和图6，在本发明的一实施例中，摆线液压马达具有承力结构简单可靠，安装定位止口尺寸小。如结构示意图图1所示，摆线液压马达包括具有安装固定法兰面的体壳10，安置在体壳10内的扭矩输出的输出轴11，以及与所述体壳10采用连接螺栓12固连的连接转定子副13、配流系统14和油液进出马达内腔的后盖15；所述的体壳10具有SAE A型标准的Φ82.55或相近尺寸止口连接尺寸，所述的体壳10具有安装定位止口圆面，所述的体壳10后端设置了连接板16并抵靠在连接板16的一端面，所述的体壳10前端内孔设置了旋转轴封17，所述旋转轴封17对旋转输出轴11进行旋转动密封，所述的体壳10内腔前后设置支撑输出轴11的两个支撑轴承，所述的前后轴承采用圆柱滚子轴承18，所述圆柱滚子轴承18由圆柱滚子和支撑架组成，所述圆柱滚子轴承18的圆柱滚子安装在支撑架的机械加工的凹槽内，所述圆柱滚子轴承18可承受径向力和轴向力，该结构可以很好的解决本发明马达结构紧凑问题，解决了圆锥滚子轴承由于径向尺寸大，而不能设置SAE A型标准安装连接尺寸的难题，所述圆柱滚子轴承18的圆柱滚子抵靠在输出轴11的轴肩上，所述圆柱滚子轴承18同时承受输出轴11上的径向力和轴向力，所述前圆柱滚子轴承的支撑架抵靠体壳10安装孔台阶上，所述后圆柱滚子轴承的支撑架抵靠连接板16的一端面，这样圆柱滚子轴承18将受到得力传递至体壳10和连接板16上。
所述的连接板16设置了外泄油口，所述外泄油口与马达内腔相通，所述外泄油口通过单
向阀与马达的进油口和回油口沟通，所述的单向阀由钢球23、支撑体29、堵头30、密封垫31组成，所述的两个单向阀设置使得外泄油口始终与马达的回油口相通，从而保护了体壳10的旋转轴封17。较佳地，支撑体29为弹簧，堵头30上设置连接螺纹。
所述的连接板16设置了蝶形圈19，所述蝶形圈19一端抵靠输出轴11一端面，另一端安装在连接板16的台阶孔内，所述蝶形圈19设置使得马达内腔油液形成循环的油路，对零件进行润滑，以及带走热量和内腔的微细颗粒。
所述的体壳10安装法兰处设置局部凹入台阶，所述凹入台阶使得马达与驱动装置安装时，安装法兰面的固定螺栓具有足够的安装空间及其固定螺栓头部的安装空间，所述法兰面的最小处圆面与凹入台阶面相贯，所述最小处圆面与体壳10后部的连接螺栓12安装位置处得四方形柱形倒圆角相贯。
所述后盖15的油口面形状后端为局部八字形，前端为直角状形状或类似直角形状。
所述马达配流系统14的配流支撑板141外形与转定子副13的定子131外形相同，所述配流支撑板141两端面外露，所述配流支撑板141一端面与定子131端面相连，另一端面与后盖15端面相连，形成两平面接触面，两相接触面采用O型圈进行平面密封，所述的定子131、配流支撑板141和后盖15的两个接触面采用两个限位销21进行限位。
所述马达配流系统14的配流压盘142高承压能力处设置密封结构，配流压盘142的高低压的密封结构由O型圈25、27外加低压一侧设置挡圈26、28，所述挡圈26、28采用聚四氟乙烯材质制成。可以理解的是，配流压盘142的高低压的密封结构能够对进油口、回油口和腔体设置两道密封的结构，保证密封可靠。
试验证明，由于上述实施例采取了一系列有效的完善改进措施，因此将液压马达的径向力承受能力、压力承受能力提高了，并且能够承受较大的轴向力，尤其是体壳具有SAE A型标准的Φ82.55或相近尺寸止口连接尺寸，而其结构紧凑，零件加工、装配的工艺好。除上述实施例外，本发明还可以有其他实施方式，例如输出轴的支撑结构的改变、体壳的外形改变，转定子副的齿数改变，等等。凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
可以理解的是，两个支撑轴承设置于输出轴11的前后两端，即为上述的前后轴承。两个支承轴承分别为前圆柱滚子轴承与后圆柱滚子轴承。这样，前圆柱滚子轴承与后圆柱滚子轴承的圆柱滚子抵靠在输出轴11的轴肩上，通过圆柱滚子将输出轴11受到的轴向力传递到体壳10上。
参见图2至图4，在本发明的另一实施例中，为了使得本发明摆线液压马达的承力结构简单可靠，如图2所示，所述马达的体壳10具有使用时安装定位止口，所述体壳10内设置
了扭矩输出的输出轴11，所述输出轴11后端设置了中间突出轴肩，所述轴肩前后各安装并限位一个支撑轴承，所述输出轴11安装的前后支撑轴承采用圆柱滚子轴承18，所述圆柱滚子轴承18由圆柱滚子和支撑架组成，圆柱滚子安装在机械加工的支撑架的凹槽内，圆柱滚子轴承18可承受径向力和轴向力，所述输出轴11的轴肩倚靠圆柱滚子，通过圆柱滚子将输出轴11受到的轴向力传递到体壳10上，所述圆柱滚子轴承18的支撑架采用20号类低碳合金钢，经过渗碳淬火热处理后磨削工艺加工成型，使得圆柱滚子的滚道具有合适的硬度，以及使得圆柱滚子轴承18也能够承受大的轴向力。通过马达输出轴11受力结构的创新，有效的提升马达轴承安装与承受力的可靠性。
所述体壳10采用连接螺栓12固连的转定子副13、配流系统14和油液进出马达内腔的后盖15，所述配流系统14的配流支撑板141外形与转定子131副的定子131外形相同，所述配流支撑板141外露，所述配流支撑板141一端面与定子131端面相连，另一端面与后盖15端面相连，形成两平面接触面，两相接触面采用密封圈20进行平面密封,密封圈20为O型圈，所述的定子131、配流支撑板141和后盖15的两个接触面采用两个限位销21进行限位。配流支撑板141打破了传统外形圆形的配流支撑板嵌套在后盖孔内的结构，而是外露于后盖15，从而通过端面密封结构的创新，增强了密封面承能力及其可靠性，另外限位销21的设置可以十分防止结合面的相对转动位移，保证马达接合面密封质量的可靠，还有降低连接螺栓12的负荷。
所述配流支撑板141上设置了两个单向阀，分别与进油口和回油口沟通，单向阀通道设置在配流支撑板141上，通过定子131上的通道与内腔沟通，钢球23作为单向阀的单向密封体。
本发明的配流系统14的配流压盘142是对马达的进油口高压油、回油口低压油进行分流，分流后的高低压液压油分别进入配流盘143的通道，配流盘143的通道与配流支撑板141的孔道共同形成配流系统14，高低压液压油经过配流系统14的分流，进入由定子131，转子133、定子131和针齿132形成的容腔，不断地推动转子133的运动；配流压盘142的两道密封是直接与高压油液的进油口或低压油液的回油口直接连通，马达压力等级的提升，必须提高其两道密封的承压能力及其承压可靠性，配流压盘142由波形弹簧的弹性体22的弹力而紧靠在配流盘143的一端面，同样使得配流盘143的另一面紧贴靠配流支撑板141上，由于配流压盘142在马达的工作中会有轴向方向的小于1mm的位移，配流压盘142的圆周方向由销24限位。图3配流压盘142的高低压两道密封的结构示意图，配流压盘142的前端一道密封的两端既有高压又有低压的可能，前道密封的O型圈25两侧各设置一个对称安装的挡圈26，而后端一道密封的前端既有高压又有低压的可能，后端只有低压，后道密封的O型圈27后侧置一个挡圈28，所述挡圈采用聚四氟乙烯基材制成，为了便于挡圈的安装，可以将挡圈开
一个与端面成15°的开口。
在本发明的再一实施例中，本实施例的摆线液压马达基本结构如图7所示，其基本结构与本发明另一实施例的结构相同，主要的不同之处在于：其中的两个单向阀设置在后盖15上，分别与进油口和回油口沟通，单向阀通道设置在后盖15上，通过配流支撑板141、定子131上的通道与内腔沟通，单向阀由钢球23、支撑体29、堵头30、密封垫31组成。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
