Description

泵体及具有其的压缩机
技术领域
本发明涉及压缩机技术领域，具体而言，涉及一种泵体及具有其的压缩机。
背景技术
滑片式压缩机的压缩腔是由滑片与气缸内壁分隔而来，所以在传统滑片式压缩机中，滑片头部与气缸内壁面之间的相对速度很大，从而导致两者间的摩擦过大，影响功耗与性能，长期摩擦过大则会产生磨损进而影响压缩机整机的可靠性。
为了减少摩擦并提升可靠性，有的方案对传统滑片式压缩机的气缸部分进行优化改造，即使用一个轴承替代原有的气缸结构。由于滚动轴承的内圈可以转动，相较于固定不动的气缸来说，滑片头部与轴承内圈之间的相对速度会大幅度降低，进而两者之间的摩擦也将会大幅度下降，从而达到减少摩擦并提高可靠性的目的。
但此种方案会带来新的摩擦副，即轴承内圈的端面与法兰结构之间的摩擦。在低转速运行时摩擦并不明显，一旦运行速度提高便会出现摩擦过大的情况，与前述相似，这也可能会出现功耗增大或是可靠性问题。
发明内容
本发明提供了一种泵体及具有其的压缩机，以解决现有技术中泵体的内圈与法兰结构摩擦大的问题。
为了解决上述问题，根据本发明的一个方面，本发明提供了一种泵体，包括：法兰结构；轴承，轴承具有内圈和外圈，内圈可转动地设置在法兰结构上，内圈的端面与法兰结构的接触面抵接；导油通道，设置在内圈的侧壁内和/或法兰结构内，导油通道的出口位于内圈的端面和法兰结构的接触面之间，以在内圈的端面和法兰结构的接触面之间引入润滑油。
进一步地，导油通道设置在内圈的侧壁内，导油通道的出口位于内圈的端面上。
进一步地，导油通道的入口位于内圈的外周面，以从内圈和外圈之间的区域引入润滑油。
进一步地，导油通道包括：第一通道，出口位于第一通道上；第二通道，与第一通道连通，入口位于第二通道上。
进一步地，第一通道为多个，多个第一通道沿内圈的圆周方向间隔设置。
进一步地，第一通道的延伸方向与内圈的轴线平行，相邻两个第一通道之间的间距相等。
进一步地，第二通道的延伸方向与第一通道的延伸方向之间具有夹角，第二通道为多个，多个第二通道沿内圈的圆周方向间隔设置，多个第二通道一一对应地与第一通道连通。
进一步地，第二通道为环形槽，环形槽环绕设置在内圈的外周面，多个第一通道均与环形槽连通，环形槽的开口形成入口。
进一步地，法兰结构包括第一法兰和第二法兰，内圈的两个端面分别与第一法兰和第二法兰抵接，内圈的两个端面上均设置有出口。
进一步地，轴承还包括：保持架，设置在外圈与内圈之间；滚动体，可转动地设置在保持架上，滚动体内设置有第三通道，第三通道用于将润滑油引入滚动体的端面与保持架的接触面之间。
进一步地，法兰结构上设置有第四通道，第四通道用于将润滑油引入到内圈和外圈之间的区域。
进一步地，泵体还包括：主轴，可转动地穿设在内圈中，主轴内设置有第五通道，第五通道与第四通道连通，第五通道用于从外部引入润滑油。
根据本发明的另一方面，提供了一种压缩机，包括泵体，泵体为上述提供的泵体。
应用本发明的技术方案，在内圈的侧壁内或法兰结构内设置导油通道，并且导油通道的出口位于内圈的端面和法兰结构的接触面之间，这样可以通过导油通道将润滑油引入内圈的端面与法兰结构的接触面之间，从而可以起到良好的润滑效果，减少内圈的端面与法兰结构的摩擦，进而提高泵体的可靠性并降低功耗。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至图6所示，本发明的实施例一提供了一种泵体，包括：法兰结构10；轴承20，轴承20具有内圈21和外圈22，内圈21可转动地设置在法兰结构10上，内圈21的端面与法兰结构10的接触面抵接；导油通道30，设置在内圈21的侧壁内和/或法兰结构10内，导油通道30的出口位于内圈21的端面和法兰结构10的接触面之间，以在内圈21的端面和法兰结构10的接触面之间引入润滑油。
应用本实施例的技术方案，在内圈21的侧壁内或法兰结构10内设置导油通道30，并且导油通道30的出口位于内圈21的端面和法兰结构的接触面之间，这样可以通过导油通道30将润滑油引入内圈21的端面与法兰结构10的接触面之间，从而可以起到良好的润滑效果，减少内圈21的端面与法兰结构10的摩擦，进而提高泵体的可靠性并降低功耗。
在本实施例中，导油通道30可以设置在内圈21的侧壁内，这样从内圈21的侧壁内向内圈21的端面与法兰结构10的接触面之间输送润滑油；导油通道30也可以设置在法兰结构10内，这样从法兰结构10内向内圈21的端面与法兰结构10的接触面之间输送润滑油。
具体地，在本实施例中，导油通道30设置在内圈21的侧壁内，导油通道30的出口位于内圈21的端面上。这样可从内圈21的侧壁内向内圈21的端面与法兰结构10的接触面之间输送润滑油，从而可以起到良好的润滑效果，减少内圈21的端面与法兰结构10的摩擦。
如图1所示，导油通道30的入口位于内圈21的外周面，以从内圈21和外圈22之间的区域引入润滑油。由于内圈21和外圈22之间的区域空间较大，可以储存较多的润滑油，这样从此区域向导油通道30输送润滑油可以保证良好的润滑效果。
在本实施例中，导油通道30包括：第一通道31，出口位于第一通道31上；第二通道32，与第一通道31连通，入口位于第二通道32上。这样可通过第二通道32和第一通道31从内圈21和外圈22之间的区域向内圈21的端面与法兰结构10的接触面之间输送润滑油。
如图3所示，第一通道31为多个，多个第一通道31沿内圈21的圆周方向间隔设置。这样可通过多个第一通道31向内圈21的端面与法兰结构10的接触面之间的不同位置输送润滑油，使润滑油均匀分布，以提高润滑效果。
具体地，第一通道31的延伸方向与内圈21的轴线平行，相邻两个第一通道31之间的间距相等。这样可使得润滑油在内圈21的端面与法兰结构10的接触面之间的分布更加均匀。在本实施例中，可以将第一通道31的轴线设置在与内圈21的内表面和外表面距离相等的位置。
如图3至图5所示，在本实施例中，第二通道32的延伸方向与第一通道31的延伸方向之间具有夹角，第二通道32为多个，多个第二通道32沿内圈21的圆周方向间隔设置，并且多个第二通道32一一对应地与第一通道31连通。这样可通过多个第二通道32向对应的第一通道31输送润滑油，便于润滑的流动。在本实施例中，可以将第二通道32沿内圈21的径向设置。
如图1和图2所示，法兰结构10包括第一法兰11和第二法兰12，内圈21的两个端面分别与第一法兰11和第二法兰12抵接，内圈21的两个端面上均设置有出口。这样内圈21的一个端面与第一法兰11之间可以输入足够的润滑油以形成油膜，并且内圈21的另一个端面与第二法兰12之间可以输入足够的润滑油以形成油膜，从而提高润滑效果。
为了使润滑油顺畅地流动，在本实施例中，可以将导油通道30的最小截面的面积设置为大于0.5mm2。当然，与导油通道30连通的其他通道的最小截面的面积也可设置为大于0.5mm2。
如图6所示，轴承20还包括：保持架23，设置在外圈22与内圈21之间；滚动体24，可转动地设置在保持架23上，滚动体24内设置有第三通道，第三通道用于将润滑油引入滚动体24的端面与保持架23的接触面之间。这样可使得滚动体24的端面与保持架23的接触面之间具有足够的润滑油，从而可以起到良好的润滑效果，降低滚动体24与保持架23的磨损，提高轴承20的寿命。
在本实施例中，法兰结构10上设置有第四通道13，第四通道13用于将润滑油引入到内圈21和外圈22之间的区域。这样可通过第四通道13向内圈21和外圈22之间的区域输送润滑油，以保证足够的润滑油供应。润滑油可以从泵体外部引入。如图1所示，可以将第四通道13设置在第二法兰12上，第四通道13的出油口与内圈21和外圈22之间的区域连通。
在本实施例中，泵体还包括：主轴40，可转动地穿设在内圈21中，主轴40内设置有第五通道41，第五通道41与第四通道13连通，第五通道41用于从外部引入润滑油。这样可通过主轴40内的第五通道41从外部引入润滑油，然后通过第四通道13输送到内圈21和外圈22之间的区域。
在本实施例中，泵体还包括齿轮泵，齿轮泵设置在主轴40的底部，这样可通过齿轮泵为第五通道41供应润滑油，以促进润滑油的流动。
如图7和图8所示，本发明的实施例二提供了另一种泵体，与实施例一不同的是，导油通道30的第二通道32为环形槽，环形槽环绕设置在内圈21的外周面，多个第一通道31均与环形槽连通，环形槽的开口形成入口。这样可通过环形槽向多个第二通道32输送润滑油。
如图9所示，本发明的实施例三提供了另一种泵体，与实施例一不同的是，第四通道13设置在第一法兰11上，第四通道13的出油口与内圈21和外圈22之间的区域连通。
本发明的实施例四提供了一种压缩机，包括泵体，泵体为上述提供的泵体。在内圈21的侧壁内或法兰结构10内设置导油通道30，并且导油通道30的出口位于内圈21的端面和法兰结构的接触面之间，这样可以通过导油通道30将润滑油引入内圈21的端面与法兰结构10的接触面之间，从而可以起到良好的润滑效果，减少内圈21的端面与法兰结构10的摩擦和磨损，进而提高压缩机的可靠性并降低功耗。
