在圆筒形壳体的一端等角度配置几个气缸,使设在气缸里的活塞作往复运动,这就是吸排液体或气体的轴向式泵或轴向式压缩机。它特别适用于从低速运转到高速运转的车辆冷库用压缩机。其主轴贯通它的前壳体,楔形转子固定在与圆筒形壳体同心的主轴内端,并由一对齿数相等的伞齿轮防转,使楔形转子的倾斜面只能把摆动运动传给摆动盘,摆动盘的摆动运动传给气缸里的活塞并使之作往复运动。这种摆动式压缩机,由于其结构、动作的非对称性及往复运动等原因,不能保持完全动平衡,因而造成振动。
Several cylinders are equiangularly arranged at one end of a cylindrical housing so that the piston provided in the cylinder reciprocates. This is an axial-type pump or an axial-type compressor that sucks liquid or gas. It is particularly suitable for low-speed high-speed operation of the vehicle cold storage compressor. Its main shaft through its front shell, the wedge rotor is fixed to the cylindrical inner concentric end of the spindle, and by a pair of equal number of bevel gear anti-rotation, the wedge-shaped rotor tilted surface can only pass the swing movement Swing plate, wobble plate swing motion to the piston in the cylinder and make it reciprocating motion. This swing compressor, due to its structure, asymmetry of motion and reciprocating motion and other reasons, can not maintain complete dynamic balance, thus causing vibration.
