Abstract

一种压缩机，可以压缩气体和液体。主要由凸轮转子，凹轮转子，同步齿轮，壳体构成。凸轮转子与凹轮转子由同步齿轮约束同步旋转并装配在壳体内。凸轮转子是一圆轮开T槽并镶上T形的凸轮挡块构成。凹轮转子是一圆轮开槽使凸轮转子与凹轮转子相应旋转时让凸轮挡块通过。凸轮转子与凹轮转子旋转时在壳体内形成两个容积可以变化的腔体。凸轮挡块旋转方向后面可以变大的腔体称为吸收腔体，凸轮挡块旋转方向前面可以变小的腔体称为压缩腔体。凸轮挡块旋转把压缩腔体里面的压缩气体（液体）从止回阀排出。吸收腔体形成负压，气体（液体）从进口进入吸收腔体。该压缩机是全机械式的，结构简单可靠。

Description

凸轮压缩机
发明名称：凸轮压缩机
技术领域:本发明属于压缩机领域的新式压缩机。主要由凸轮转子，凹轮转子，同步齿轮，壳体构成。背景技术：目前市场上的空压机有离心式，轴流式，往复式，螺杆式，滑片式等空压机。上述的空压机各有各的优点，但加工制造也相对复杂，螺杆空压机还要专业的机器来加工。凸轮压缩机加工简单，结构结实。不但可以压缩气体还可以压缩液体。
其特征在于：所述凸轮转子2与凹轮转子3由一组相互啮合并且相同齿数、模数的同步齿轮5约束同步旋转。并精密装配在壳体1内，由前端盖6与后端盖7固定在壳体1内。所述凸轮转子2是一圆轮开T槽并镶上T形的凸轮挡块8构成。所述凹轮转子3是一圆轮开槽使凸轮转子2与凹轮转子3相应旋转时让凸轮挡块8避空通过。如图1所示。所述凸轮转子2为主动轮带动从动轮凹轮转子3旋转，图1至图5是凸轮转子2与凹轮转子3每旋转90度的状态。凸轮转子2旋转时与凹轮转子3在壳体1内形成两个容积可以变化的腔体。凸轮挡块8旋转方向后面可以变大的腔体称为吸收腔体19，凸轮挡块8旋转方向前面可以变小的腔体称为压缩腔体20。随着凸轮转子2的旋转凸轮挡块8前面压缩腔体20的容积逐渐变小，压缩腔体20里面的气体（液体）由于压力增大使压缩气体（液体）从止回阀12排出。如图4。同时由于凸轮挡块8后面的吸收腔体19的容积逐渐变大，吸收腔体19形成负压，气体（液体）从进口13进入吸收腔体19，如图3所示。当凸轮转子2与凹轮转子3旋转1周后进入吸收腔体19里面的空气（液体）由于凸轮转子2与凹轮转子3隔断又形成新一轮的压缩空气（液体）的工作循环。该凸轮压缩机是全机械式的，结构简单可靠，容易加工。
当两个面距离为零时理论上可以密封液体和气体。经过多次测试当两个面距离为0.01MM-0.03MM时高压气体和液体的泄露量很少，随着距离增大高压气体和液体的泄露量越大。在这里压缩腔体20取一个即能相对密封又能活动的距离，双边距离为0.01MM-0.1MM，在这里称为临界密封。凸轮转子2与凹轮转子3的圆柱面距离尽量减少但不能接触。虽然工作时机器内部有少量气体、液体泄露但在快速旋转的情况下可以忽略不计。凸轮压缩机的凸轮转子2与凹轮转子3、壳体1、前端盖6、后端盖7的密封全部采用临界密封，也可以采用密封环（片）密封。临界密封的优点就是工作部件表面没有接触、摩擦、保证无损耗的情况下又能密封气体、液体。由于没有损耗机器的耐用性以及寿命自然提高。
附图说明：图1是凸轮挡块8通过凹轮转子3的剖面图，该图通过仿真旋转没有相互干涉。图1至图4是凸轮转子2与凹轮转子3每旋转90度的状态。图5是凸轮转子2与凹轮转子3旋转1周后新一轮压缩工作的开始。图6是左侧剖视图，图7是爆炸图各部件名称，图8是立体爆炸图。
附图各部件名称：1、壳体 2、凸轮转子 3、凹轮转子 4、齿轮保护罩 5、同步齿轮6、前端盖 7、后端盖 8、凸轮挡块 9、角接触球轴承 10、定位销 11、轴承盖 12、止回阀 13、进口 14、出口 15、卡簧 16、平键 17、吊换 18、杯头螺丝 19、吸收腔体 20、压缩腔体 21、机械密封 22、机械密封端盖。
