Embodiment 1
[0040] Such as figure 1 with figure 2 As shown, the rotary translational piston compressor includes a motor 103 , a cylinder 104 , a crankshaft 101 , blades 105 , a piston 106 and a spring 111 .
[0041] The cylinder 104 includes a cylinder body 12 and a cylinder head 1 , and a piston chamber 2 and vane grooves are provided in the cylinder 104 .
[0042] The crankshaft 101 has an eccentric portion 102 , the crankshaft 101 passes through the piston cavity 2 of the cylinder 104 , and the eccentric portion 102 is located in the piston cavity 2 . The rotating shaft of the motor 103 is connected with the crankshaft 101 .
[0043] The vane 105 is embedded in the vane slot and can slide along the side wall of the vane slot. The piston 106 is sleeved on the eccentric portion 102 . The spring 111 is located in the vane groove, one end of the spring 111 abuts against the other end of the vane 105 , the other end of the spring 111 abuts against the cylinder 104 , and the spring 111...
Embodiment 2
[0049] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: image 3 with Figure 4 As shown, in order to further reduce the coefficient of friction between the piston 106 and the eccentric part 102, a first helical groove 5 is provided on the outer surface of the eccentric part 102, and an oil supply passage communicating with the first helical groove 5 is provided in the crankshaft 101. 6. When the rotary translational piston compressor works, lubricating oil enters the gap between the anti-friction sleeve 4 and the eccentric part 102 through the oil supply channel 6 . The provision of the first spiral groove 5 makes it easier for lubricating oil to fill the above-mentioned gaps, that is, to avoid the phenomenon of oil shortage in the above-mentioned gaps during high-speed operation. Supplying lubricating oil in the above-mentioned gap can also take away the heat generated by friction, so as to prevent the a...
Embodiment 3
[0051] The structure and principle of the present embodiment are basically the same as those of the second embodiment, the difference is that: Figure 5 As shown, the rotary translational piston compressor also includes a second helical groove 7 located on the outer surface of the anti-friction sleeve 4, and the anti-friction sleeve 4 is provided with a cavity connecting the second helical groove 7 and the inner cavity of the anti-friction sleeve 4. The first communication hole 8 . That is, lubricating oil enters the gap between the anti-friction sleeve 4 and the piston 106 through the first communication hole 8 ; the second spiral groove 7 makes it easier for the lubricating oil to fill the gap.
