Description

螺杆压缩机和空调
本申请是以CN申请号为202010008013.9，申请日为2020年1月6日的申请为基础，并主张其优先权，该CN申请的公开内容在此作为整体引入本申请中。
技术领域
本公开涉及压缩机技术领域，特别涉及一种螺杆压缩机和空调。
背景技术
通常螺杆压缩机中布置有一对平行的螺旋转子，该对转子与壳体内壁形成空间容积。转子在旋转过程中，该容积会周期性的增大和减小。通过合理的设计，使该容积与进气口和排气口周期性的连通和关闭，从而可以完成吸气、压缩和排气的全过程。目前双螺杆压缩机广泛应用于中等冷量范围的制冷空调中。
在一些特定的应用场合，比如安装于地下室的设备需要更换压缩机时，由于场所的尺寸限制，只允许较小的压缩机进入。由于压缩机的尺寸由排气量的大小决定，若选用较小尺寸的压缩机会导致排气量变小而无法满足用户的需求。因此需要研发在排气量不变的情况下而尺寸较小的压缩机。
发明内容
本公开提供一种螺杆压缩机和空调，以在缩小尺寸的基础上还能保证排气量。
在本公开的一个方面，提供一种螺杆压缩机，包括：
壳体；和
转子组件，可转动地设置于壳体内且包括转轴以及依次同轴设置于转轴上的第一转子和第二转子，第一转子和第二转子的螺纹旋向相反，第一转子和第二转子的相互靠近的端面接合，壳体的与接合处对应的位置设置有吸气口。
在一些实施例中，第一转子和第二转子的齿形相同且长度相等。
在一些实施例中，在转轴的轴向方向上，壳体的两端设置有排气口。
在一些实施例中，第一转子和第二转子通过连接件连接于转轴上。
在一些实施例中，连接件包括周向连接件，周向连接件被配置为在周向上对第一转子和第二转子定位；和/或，连接件包括轴向连接件，轴向连接件被配置为在轴向上 对第一转子和第二转子定位。
在一些实施例中，第一转子和第二转子均包括与转轴配合的轴孔，轴孔与转轴之间采用紧配合。
在一些实施例中，螺杆压缩机包括平行设置的两个转子组件，两个转子组件沿相反方向转动，且两个转子组件的相对应的转子相互啮合。
在一些实施例中，两个转子组件包括阳转子组件和阴转子组件，其中，阳转子组件的转子的螺纹齿的材料包括peek材料；和/或，阴转子组件的转子的螺纹齿的材料包括45号钢。
在一些实施例中，转子组件还包括设置于第一转子一侧以及设置于第二转子一侧的滑动轴承。
在一些实施例中，滑动轴承包括外圈，转轴包括轴颈，轴颈形成内圈，外圈同轴设置于轴径的外周面外侧且相对于轴颈可转动。
在本公开的另一方面，提供一种空调，包括如上述的螺杆压缩机。
基于本公开提供的技术方案，螺杆压缩机包括壳体和转子组件，转子组件可转动地设置于壳体内且包括转轴以及依次同轴设置于转轴上的第一转子和第二转子，第一转子和第二转子的螺纹旋向相反，第一转子和第二转子的相互靠近的端面接合，壳体的与接合处对应的位置设置有吸气口。本公开的螺杆压缩机的两对转子对称布置相当于两台螺杆压缩机并联，那么在相同排气量的情况下该螺杆压缩机的尺寸可以大大减小。而且本公开的螺杆压缩机的第一转子和第二转子相互靠近的端面接合使得螺杆压缩机从接合处吸气，气体分别流向两侧的转子进行压缩排气，整个螺杆压缩机的结构更加紧凑。
通过以下参照附图对本公开的示例性实施例的详细描述，本公开的其它特征及其优点将会变得清楚。
附图说明
为了更清楚地说明本公开实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开中记载的一些实施例，对于本领域普通技术人员来讲，还可以根据这些附图获得其他的附图。
图1为本公开实施例的螺杆压缩机的内部结构示意图；
图2为图1中的阳转子组件的爆炸结构示意图；
图3为图1中的阳转子组件的剖面结构示意图；
图4为图1中的阴转子组件的爆炸结构示意图；
图5为图1中的阴转子组件的剖面结构示意图。
具体实施方式
为了使本公开的目的、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，对本公开的螺杆压缩机和空调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公开，并不用于限定本公开。
参考图1至图5，本公开实施例的螺杆压缩机包括：
壳体1；和
转子组件，可转动地设置于壳体1内且包括转轴以及依次同轴设置于转轴上的第一转子和第二转子，第一转子和第二转子的螺纹旋向相反，第一转子和第二转子的相互靠近的端面接合，壳体1的与接合处A对应的位置设置有吸气口。
本公开实施例的螺杆压缩机的两对转子对称布置相当于两台螺杆压缩机并联，那么在相同排气量的情况下该螺杆压缩机的尺寸可以大大减小。而且本公开实施例的螺杆压缩机的第一转子和第二转子相互靠近的端面接合使得螺杆压缩机从接合处吸气，气体分别流向两侧的转子进行压缩排气，整个螺杆压缩机的结构更加紧凑。
本实施例的螺杆压缩机包括平行设置的两个转子组件，两个转子组件沿相反方向转动，且两个转子组件的相对应的转子相互啮合。
具体地，如图1至图5所示，本实施例的螺杆压缩机包括平行设置的阳转子组件2和阴转子组件3。阳转子组件2包括阳转子轴21以及同轴设置于阳转子轴21上的第一阳转子22和第二阳转子23，第一阳转子22和第二阳转子23相互靠近的端面接合。同样地，阴转子组件3包括阴转子轴31以及同轴设置于阴转子轴31上的第一阴转子32和第二阴转子33，第一阴转子32和第二阴转子33相互靠近的端面接合。
第一阳转子22和第一阴转子32位置对应且相互啮合，第二阳转子23和第二阴转子33位置对应且相互啮合。如图1所示，气体在从壳体1的吸气口进入壳体1内后在接合处A分为两路分别由两侧相互啮合的转子吸入并进行压缩。
在转轴的轴向方向上，本实施例的壳体1的两端设置有排气口。
如图2所示，本实施例的第一阳转子22和第二阳转子23的齿形相同且长度相等。 也就是说，本实施例的第一阳转子22和第二阳转子23对称布置。同样地，本实施例的第一阴转子32和第二阴转子33对称布置。
如图3所示，第一阳转子22和第二阳转子23通过连接件连接于转轴上。连接件包括周向连接件，周向连接件被配置为在周向上对第一阳转子22和第二阳转子23定位。具体地，如图3所示，周向连接件为键24。第一阳转子22和第二阳转子23通过同一个键24与阳转子轴21连接，该键24起到传递力矩的作用。
本实施例的连接件还包括轴向连接件，轴向连接件被配置为在轴向上对第一阳转子22和第二阳转子23定位。如图3所示，轴向连接件包括锁紧螺母26。本实施例的转轴具有与第二阳转子23的右侧端面抵接的台阶面，第一阳转子22与第二阳转子23抵接并通过锁紧螺母26进行锁紧。可选地，本实施例的连接件还包括设置于锁紧螺母26与第一阳转子22之间的垫片25。
如图2所示，本实施例的第一阳转子22和第二阳转子23均包括与阳转子轴21配合的轴孔，轴孔与阳转子轴21之间采用紧配合。
阴转子组件3的各个部件的连接方式如图4和图5所示，与阳转子组件2的各个部件的连接方式基本相同，在此不再赘述。
本实施例的阳转子组件2的转子的螺纹齿包括peek(聚醚醚酮)材料。且阴转子组件3的转子的螺纹齿包括45号钢。且阴转子组件3的转子的螺纹齿的表面设置有陶瓷涂层。
本实施例的同轴安装于转轴上的两个转子的端面之间接触，因此只需要在转轴的两侧设置轴承，进一步使得本实施例的螺杆压缩机的结构紧凑并且由于减少了轴承的使用数量，降低成本。
具体地，本实施例的转子组件还包括设置于第一转子一侧以及设置于第二转子一侧的滑动轴承。本实施例的滑动轴承包括外圈，转轴包括轴颈，轴颈形成内圈，外圈同轴设置于轴颈的外周面外侧且相对于轴颈可转动。本实施例的滑动轴承利用轴颈形成内圈，使得滑动轴承仅包括外圈，因此结构简单进而简化整个螺杆压缩机的结构并缩小体积，进一步缩小压缩机的尺寸。
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。
在本公开描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
同时，本说明书中所引用的如“上”、“下”、“左”、“右”、“中间”及“一”等的用语，亦仅为便于叙述的明了，而非用以限定本公开可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本公开可实施的范畴。
以上所述实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本公开专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
