Description

滚动转子式压缩机
所属领域
本发明涉及一种旋转活塞式压缩机， 特别是一种滚动转子式压缩 机。 背景技术
随着生产技术的不断进步， 传统的滚动转子式压缩机以其结构简 单、 紧凑和高效的突出优点， 很快得到广泛的应用。 但是， 由于本身 的密封条件差， 因而对生产有着^ ^高的要求， 特别是对于要把滚动转 子外圆表面与缸壁之间对效率影响敏感而又最不容易保证的径向间隙 最终控制在尽可能 'j、的认可范围内， 就要对涉及影响到这一间隙的多 个相关零件的加工和装配精度制订出近乎苛刻的生产要求， 只有在依 靠于专用的高精密度工艺装备和严格复杂的生产管理方可达到。 因此 需要很大的投入。 而且在使用中， 这密封间隙会随着各运动副磨损而 不断地累积扩大， 日渐加大了泄漏量而降低效率， 无法保持其长期使 用的高效性。 目前， 虽有一些针对性的间隙补偿技术并部份地得以实 施， 但可靠性仍不理想。
另外， 在现有的滚动转子式压缩机中影响工作效率的另一主要因 素是， 由于缸体的吸、 排气火间设置的往复式隔离挡块在工作中以高 速进行往复运动， 质量惯性大， 相应而导致了较大的机械损耗和振动 而降低了工作效率， 而且该种往复式隔离挡块也会大大地增加了压缩 机运行中的噪声。
发明内容
本发明的主要目的是为了解决上述问题， 提出一种滚动转子式压 缩机， 以简单的改进方案， 在降低加工精度要求的情况下， 达到提高 压缩机的效率的目的； 本发明另一目的是降低压缩机的噪声。
实现本发明的目的第一种方案是； 一种滚动转子式压缩机， 包括 开设有吸气口和排气口的缸体、 滚动转子、 驱动轴， 其特征在于， 在 驱动轴的偏心轴部份与滚动转子间设置有能在它们之间灵活转动的偏 心套； 偏心套的内圆圆心与驱动轴 4的偏心轴部份轴心重合于 02 , 而 外圆圓心则与滚动转子的内外圆公共圆心自重合于 03, 滚动转子的公 共圆心 03相对于驱动轴的主轴轴心 0 的偏心 巨 e被偏心套 的内外圓 圆心 02和 03之间的偏心 e2和驱动轴偏心轴部份的轴心 02与主轴轴 心 之间的偏心距 e 决定， 并因此调整滚动转子的调节偏心距 e, 实现柔性滚动的密封结构。 在偏心套与滚动转子间设置有滚动装置， 以利其转动灵活性。
实现本发明的第二种方案是， 一种滚动转子式压缩机， 包括开设 有吸气口和排气口的缸体、 滚动转子、 驱动轴。 其特征在于在缸体的 吸气口与进气口之间设置有摆动隔离装置， 该摆动隔离装置至少包括 有一摆动动挡块， 该摆动挡块于吸气口和排气口之间转动， 并与缸体 以及滚动转子间形成转动式柔性密封结构。 该摆动挡块可设有弹性复 位装置。 摆动挡块的转动部分是支承于缸体的吸气口与排气口之间所 开设的向内腔开放一异型腔中的缺圆型腔部份内， 而摆动部分则被这 异型腔中的与之相对型面相吻合的型腔部分所容纳。
由上述说明可以得知， 本发明是通过对压缩机的两点改进来实现 提高压缩机的效率。
其一， 本发明中针对滚动转子外圆表面与缸壁间的径向间隙是通 过一个过渡偏心元件的设置， 而实现一种缸体与滚动转子间柔性滚动 接触式密封， 因此在工作时， 可以根据工作压力和离心力， 自动调整 滚动转子的外圆表面对缸体缸壁的压力， 达到最佳的密封效果， 并因 此而提高压缩机的效率。
其二， 本发明所作出的第二个改进方案是， 在吸气口与进气口间 由摆动挡块的转动来实现一种摆动式的间隔方式， 实现挡块与缸体间 以及摆动挡块与滚动转子间的柔性密封结构。 因此有效地降低了机械 损耗和机械振动， 并因此提高压缩机的效率。 另外此次改进不可避免 现有技术中往复式隔离挡块高速运动而产生的噪声。
上述两项对两个压缩内的最重要的两处改进是基于对两个运动副 间的运动方式改变， 使得该两处均可获得一种柔性滚动或者转动式的 间隙密封， 从而确保本发明长期使用的高效性。 本发明人经大量的试 验证明， 单独采用本发明其中任一种改进方案均能有效地提高压缩机 的工作效率。 但同时采用本发明的两种改进方案， 效果更为显示著。 另外， 本发明改进方案简单， 更容易实施。 附图简要说明 图 1本发明的工作原理图；
图 2本发明结构的立体解剖图之一;
图 3本发明结构的立体解剖图之二。 发明的最佳方式
请参见图 1 , 本发明滚动转子式压缩机包括开设有吸气口 6和排 气口 9缸体 1 , 滚动转子 2和驱动轴 4。 经驱动轴 4的主轴轴心 为 旋转中心并给予驱动轴 4如图示方向的旋转动力， 驱动轴 4的偏心轴 部份就通过偏心套 3带动滚动转子 2而围绕主轴轴心 旋转工作， 本 发明的特征是， 偏心套 3的内圓圓心与驱动轴 4的偏心轴部份轴心重 合于 02， 而外圆圓心则与滚动转子 2的内外圆公共圆心自重合于 03。 这样， 滚动转子 2的公共圆心 03相对于驱动轴 4 的主轴轴心 的偏 心距 e被偏心套 3 的内外圓圆心 02和 03之间的偏心距 62和驱动轴 4 偏心轴部份的轴心 02与主轴轴心 之间的偏心距 所决定， 从而使 滚动转子 2有了被调节偏心距 e的功能， 使其在工作中， 可以根据工 作压力的离心力， 自动调整外圆表面对缸体 1 缸壁的压力， 实现柔性 滚动接触式密封。 同时摆动隔离装置是的摆挡块 7通过在转动部份两 侧设置的螺旋弹簧 8的弹簧力作用， 以摆动部分面向滚动转子 2—侧 的端面紧压在其外圆表面上， 4巴虹体 1的内腔分隔出吸气腔 5和压缩 腔 11， 随着滚动转子 2的旋转工作， 这两部份的体积发生周期的体积 变化， 并且， 摆动挡块 7围绕着被支撑在缸体 1的吸气口 6和排气口 9 之间的转动部份来回摆动， 实现摆动式隔离。 工作气体从吸气口 6 进入吸气腔 5 , 之后进入压缩腔 11经压缩达到一定的压力后开启单向 阀 10从排气口 9排出。
本实施例中， 摆动隔离装置中所述的摆动挡块 Ί 的转动部份是被 支撑在缸体 1的吸气口 6与排气口 9之间所开设的向内腔开放的一异 型腔中的缺圆型腔部份内， 而摆动部分则被这异型腔中的与之相对型 面相吻合的型腔部分所容纳。 在摆动挡块 7 的转动部分两径向侧面围 绕转动中心分别开有环形凹槽， 螺旋弹簧 8 分别套入转动中心的芯轴 上， 一固定端插入环形凹槽内所开设的小圆孔内， 另一固定端插入前 端盖 13、 后端盖 14、 缸隔板 15、 缸体 1在相应位置上开设的小圆孔 内， 在摆动部分面各滚动转子 2的型面内开设一内 IHJ型腔。
图 2所示， 本发明中偏心套 3与滚动转子之间、 驱动轴 4的主轴 前、 后部份与前端盖 13、 后端盖 14 的轴支承之间的各主要动动副以 最简单的滑动方式配合， 构成基本结构形式。
图 3所示， 由于有了自动调节滚动转子 1的偏心距 e的功能， 在 偏心套 3与滚动转子 2之间设置滚动装置 16 , 该装置是由滚动体和隔 离圈所组成。 在驱动轴 4的主轴前、 后部份与前端盖 1 3、 后端盖 14轴 支撑之间分别设置前滚动轴承 17 和后滚动轴承 18 , 以滚动方式配合 的各主要运动副可以进一步减少摩擦损失， 而气密性并不因此而受到 影响。
本发明的优点是简化了生产和保证长期使用的高效性； 摆动挡块 7在工作中摆动质量惯性小， 有利于提高效率和降低噪声。
