供油机构和具有该供油机构的卧式压缩机
本申请要求以下中国专利申请的优先权：于2017年12月27日提交中国专利局的申请号为201721861898.7、发明创造名称为“供油机构和具有该供油机构的卧式压缩机”的中国专利申请。该专利申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及压缩机领域，更具体地，涉及在供油机构方面做出改进的卧式涡旋压缩机。
背景技术
压缩机一般包括壳体、容纳在壳体中的压缩机构、向压缩机构提供动力的马达、由马达驱动的旋转轴以及为压缩机的各个活动部件供给润滑油的供油机构等。对于立式压缩机而言，通常在压缩机壳体的底部设置有油池并且在旋转轴的底端设置有油泵，以将油池中积蓄的润滑油泵送至旋转轴中的轴向延伸的油孔，从而为压缩机的各个活动部件供给润滑油。
然而，在一些应用中，例如由于空间的限制，需要使用卧式压缩机。由于卧式压缩机不能在旋转轴的末端自然形成油池，因此提出了一些用于卧式压缩机的供油机构来实现润滑油的积蓄和泵送。例如，对于高压侧压缩机而言，可以设置隔板以在高压区中分隔出具有压力差(排出压力差)的两个隔室从而在压力较低的隔室中形成借助于压力差而能够上升的油池，以便将高压润滑油输送至旋转轴末端的油泵(单个油泵)中。然而，根据这种方式，由于在不同工况下压降不同，因此供油受到工况的影响较大，从而导致在整个压缩机运行范围中供油的一致性不良。又例如，对于低压侧压缩机而言，可以将高压区的高温高压润滑油引入到旋转轴末端的油泵中、可以利用双层外壳而低压区中形成油池、或者可以利用竖向平直分隔件在低压区中分隔出单独的油池。然而，在这些用于低压侧压缩机的供油方案中，由于需要从高压区引入高温高压润滑油而可能会对压缩机的运行性能造成不利影响或者导致需要设置结构复杂的用于限制供油量的限制结构，或者由于需要设置双壳体而导致至少径向尺寸不利地变大。而对于利用竖向平直分隔件在低压区中分隔出单独的油池的相关方案 而言，由于未考虑例如马达室中的自由空间的充分利用或者未考虑油泵的质量检查的容易程度等等而会存在一定问题。
这里，应当指出的是，本部分中所提供的技术内容旨在有助于本领域技术人员对本公开的理解，而不一定构成现有技术。

具体实施方式
下面参照附图、借助具体实施方式对本公开进行详细描述。对本公开的以下详细描述仅仅是出于说明目的，而绝不是对本公开及其应用或用途的限制。
首先，参照图1概要地描述应用有根据本公开的供油机构100的卧式压缩机10的结构。
在图示的示例中，卧式压缩机10为低压侧涡旋压缩机。然而，应当理解，根据本公开的供油机构100也可以应用于其它卧式压缩机。
如图1所示，卧式压缩机10可以包括壳体20、马达30、由马达30驱动的旋转轴40和支承旋转轴40的轴承座50。壳体20可以包括壳体本体20a以及分别位于壳体本体20a的两端的第一端盖20b和第二端盖20c。另外，卧式压缩机10还可以包括压缩机构60和隔板(消音板)70。压缩机构60可以由旋转轴40驱动从而对工作流体(例如制冷剂)进行压缩。隔板70可以将由壳体20(具体地，由壳体本体20a、第一端盖20b和第二端盖20c)限定的内部空间分隔为高压区(如图1中位于隔板70的左侧的区域)与低压区(如图1中位于隔板70的右侧的区域)。
附加地参照图2至图4，用于卧式压缩机10的根据本公开示例性实施方式的供油机构100可以包括分隔件120。分隔件120可以呈具有允许轴承座50穿过的中央孔口129的环形(例如大致圆环形)。分隔件120可以设置成在壳体20中分隔出储油室OC与设置有马达30的马达室MC。这里，可以理解，位于轴向一侧的储油室OC和位于轴向另一侧的马达室MC均处在低压区中。
特别地，分隔件120的径向外部可以构造成接合至壳体20的内周面22而分隔件120的径向内部可以构造成联接至轴承座50的外周面52。由此，通 过分隔件120而简单地和可靠地在壳体20中分隔出储油室OC与马达室MC。
在图示的示例中，分隔件120的径向外部可以构造成接合至壳体本体20a和第二端盖20c两者。以此方式，可以使壳体本体20a、第二端盖20c和分隔件120这三者更加稳定地接合。
根据本公开，分隔件120构造成具有朝向储油室OC敞开的环形凹槽128。
在如图1至图4所示的示例中，分隔件120可以包括分隔件本体121、作为分隔件120的径向内部的背离储油室OC延伸的内凸缘部122、作为分隔件120的径向外部的朝向储油室OC延伸的外凸缘部123以及位于分隔件本体121与内凸缘部122之间的朝向储油室OC凸出的弯曲部124。由此，由分隔件本体121、外凸缘部123和弯曲部124共同限定环形凹槽128。亦即，由分隔件120本身而无需借助于例如轴承座50等其它部件来可靠地形成环形凹槽128。
在分隔件120的径向外部(即外凸缘部123)的外周面处可以形成有突脊123a。突脊123a可以插置在壳体20的壳体本体20a与端盖20c之间。以此方式，可以在壳体本体20a与第二端盖20c组装在一起之后，从壳体20外侧方便地在突脊123a处将壳体本体20a、第二端盖20c和分隔件120这三者例如焊接在一起。
供油机构100还可以包括设置在分隔件120的径向内部(即内凸缘部122)与轴承座50的外周面52之间的环形密封构件140。以此方式，分隔件120与轴承座50可以经由环形密封构件140而彼此联接(这里，分隔件120与轴承座50可以彼此接触也可以彼此不接触)。由此，尤其是在分隔件120的径向外部接合至壳体20的内周面22的情况下，分隔件120与轴承座50之间的联接和密封可以简单地仅仅经由环形密封构件140而无需借助于其它紧固装置来实现。
在一些示例中，可以在分隔件120的径向内部(即内凸缘部122)的内周面处形成有密封件凹槽122a(参见图7和图9)，环形密封构件140可以容纳在密封件凹槽122a中。在其它示例中，则可以在轴承座50的外周面52处形成有密封件凹槽52a(参见图2)，环形密封构件140可以容纳在密封件凹槽52a中。另外，可以理解，也可以在分隔件120的径向内部的内周面和轴承座 50的外周面52两者处均形成有用于容纳环形密封构件140的密封件凹槽。由于设置有用于容纳环形密封构件140的密封件凹槽，可以进一步可靠地实现分隔件120与轴承座50之间的联接和密封。
在优选的示例中，分隔件120为通过深拉伸工艺而制成的一体部件。
特别地，通过深拉伸工艺，可以将分隔件120制成为使得分隔件120的限定环形凹槽128的分隔件本体121朝向马达室MC偏移(相对于凸缘部或弯曲部朝向马达室MC偏移)而定位成更靠近马达30的一端。换言之，可以使分隔件120的环形凹槽128具有更大的深度。
附加地参照图5、图6、图8a和图8b，供油机构100还可以包括在旋转轴40的一端(设置有轴承座50的端部)附接至轴承座50的泵装置160。泵装置160可以与轴承座50构成泵-轴承座组件(可以预先组装在一起)。泵装置160可以包括适于将马达室MC中的润滑油输送至储油室OC的第一泵162。
可以设置用于第一泵162的进油管162a和排油管162b。特别地，排油管162b的第一端口在马达室侧连接至泵-轴承座组件而排油管162b的第二端口从马达室侧穿过形成在分隔件120处的开口127而进入储油室OC。通过设置位于泵-轴承座组件外部的分体的排油管162b，可以方便地对第一泵162进行功能性测试(质量检查)，而且，与排油通道设置在泵-轴承座组件内部的方案相比，还可以简化结构并且可以避免由于在泵-轴承座组件内部设置排油通道而导致泵-轴承座组件(特别是轴承座)的轴向长度不当增大的情况。
泵装置160还可以包括适于将储油室OC中的润滑油输送至旋转轴40中的油孔42的第二泵164。第一泵162与第二泵164可以组合在一起(例如共用位于其间的隔板)从而构成所谓的双泵结构。另外，第一泵162的能力(例如排量)可以大于第二泵164的能力(例如排量)。
在如图1所示的示例中，用于第一泵162的第一进油管162a和用于第二泵164的第二进油管164a可以构造为分别在马达室侧和储油室侧从泵-轴承座组件大致竖向向下延伸的管(例如直管)。通过这种双直管设计，可以使结构更加紧凑从而降低成本并且也可以对泵结构进行更好的质量控制。
第一进油管162a和/或第二进油管164a可以以可拆卸方式接合至泵-轴承座组件。特别地，参照图6，第一进油管162a和/或第二进油管164a可以具有 螺纹结构从而适于旋拧至泵-轴承座组件，或者，第一进油管162a和/或第二进油管164a可以构造成通过定位销172和螺纹紧固件174而固定至泵-轴承座组件。由此，有利于第一进油管162a和第二进油管164a的组装、拆卸和质量检查。
卧式压缩机10还可以包括用于固定轴承座50的轴承座支架59。分隔件120为与轴承座支架59不同的部件。换言之，用于限定储油室OC的分隔件120独立于用于支撑轴承座50的轴承座支架59。由此，可以更加可靠地形成储油室OC并且可以更加可靠地实现轴承座50的稳定支撑，而且，也使得分隔件120与轴承座50之间的联接和密封可以简单地仅仅经由环形密封构件140而无需借助于其它紧固装置来实现成为可能。
根据上述示例性实施方式，由于通过例如深拉伸工艺而使分隔件限定有朝向储油室敞开的具有较大深度的环形凹槽，因此能够减小或最小化马达室中的自由空间(无用的空闲空间)从而在储油室的大小相同的情况下能够减小卧式压缩机的整体尺寸(尤其是轴向尺寸)。另外，通过具有环形凹槽和朝向储油室延伸的外凸缘部的分隔件，能够在允许分隔件与壳体本体和端盖两者接合从而实现稳定接合的同时实现马达室中的自由空间的减小或最小化。另外，通过具有内凸缘部的分隔件，可以允许分隔件与轴承座的可靠及稳定的联接和密封。另外，通过具有朝向储油室凸出的弯曲部的分隔件，可以在适当地避免与轴承座周围的相关部件相干涉的同时实现马达室中的自由空间的减小或最小化。
下面参照图7、图8a和图8b描述根据本公开的供油机构100的变型例。在该变型例中，供油机构100的分隔件120未采用深拉伸工艺制造并且分隔件120的分隔件本体121呈大致平直状。另外，在该变型例中，用于第一泵162的第一进油管162a和用于第二泵164的第二进油管164a未采用从泵-轴承座组件大致竖向向下延伸的管(例如直管)而是采用例如通过钎焊进行连接的弯曲管。然而，在该变型例中，由于分隔件120同样地构造成具有朝向储油室OC敞开的环形凹槽128，因此也能够实现与上述示例性实施方式基本相同的有益效果。另外，在该变型例中，同样地设置有位于泵-轴承座组件外部的分体的排油管162b，因此也可以方便地对第一泵162进行功能性测试(质量检查)，而且，与排油通道设置在泵-轴承座组件内部的方案相比，也可以简化结构并且可以避免由于在泵-轴承座组件内部设置排油通道而导致泵-轴承座组 件(特别是轴承座)的轴向长度不当增大的情况。
下面参照图9描述根据本公开的分隔件120的另一变型例。在该另一变型例中，与上述示例性实施方式相比，分隔件120同样地为通过深拉伸工艺而制成的一体部件，只是分隔件120不包括有弯曲部并且内凸缘部122’的延伸方向不同。具体地，在另一变型例中，分隔件120包括分隔件本体121、作为分隔件120的径向内部的内凸缘部122’以及作为分隔件120的径向外部的外凸缘部123，内凸缘部122’和外凸缘部123朝向储油室OC延伸，从而由分隔件本体121、内凸缘部122’和外凸缘部123共同限定环形凹槽128。根据另一变型例，也能够实现与上述示例性实施方式基本相同的有益效果。
根据本公开的供油机构100还容许各种可行的其它变型。例如，分隔件120可以不构造成具有朝向储油室OC敞开的环形凹槽128而是关注于设置有位于泵-轴承座组件外部的分体的排油管162b。而且，在不具有环形凹槽128而是设置有位于泵-轴承座组件外部的分体的排油管162b的技术方案中，可以结合有如上文所描述的各个技术点中的一个或多个，只要这种结合在技术上是可兼容的。
虽然已经参照示例性具体实施方式对本公开进行了描述，但是应当理解，本公开并不局限于文中详细描述和示出的具体实施方式，在不偏离权利要求书所限定的范围的情况下，本领域技术人员可以对示例性具体实施方式做出各种改变。
