Problems solved by technology
[0003] The function of the crankshaft is to transmit the power of the rotor to the pump body. The crankshaft needs sufficient rigidity, and the casting needs wall thickness to increase strength and prevent deflection and deformation from increasing bearing wear. The revolution of the crankshaft itself produces useless power consumption. The power consumption is related to the crankshaft. Weight related, detrimental to compressor performance

The invention discloses a crankshaft for a compressor and a compressor having the same. The crankshaft includes: a first steel pipe, a second steel pipe, an upper thrust wall and a lower thrust wall. The first steel pipe is suitable for being sleeved on the rotor so as to be driven to rotate by the rotor. The second steel pipe is sheathed on the first steel pipe, and the central axis of the second steel pipe deviates from the central axis of the first steel pipe, and the piston is adapted to be sheathed on the outer peripheral wall of the second steel pipe. The upper thrust wall is located on the top of the second steel pipe and is sheathed on the first steel pipe. The lower thrust wall is located at the bottom of the second steel pipe and is sheathed on the first steel pipe. According to the crankshaft of the embodiment of the present invention, the weight of the crankshaft can be greatly reduced, the cost of the crankshaft can be reduced, and the counterweight of the main balance weight of the compressor can be reduced. At the same time, the steel pipe has high strength, high rigidity and wear resistance, reducing bearing wear. At the same time, the eccentric mass of the compressor is reduced, the reliability of the compressor is improved, the useless power consumption generated by the high-speed operation of the crankshaft is reduced, and the performance of the compressor is improved.
Description
technical field [0001] The present invention relates to the technical field of compressors, and in particular, to a crankshaft for a compressor and a compressor having the same. Background technique [0002] The crankshaft structures of the existing rotary compressors are all integral castings and are solid castings, which are heavy, expensive, and difficult to process. The mass of the solid eccentric circle constitutes the main part of the eccentric mass. The mass of the eccentric circle can affect the balance weight on the rotor and the centrifugal inertial force generated by the eccentric mass of the compressor that is not concentric with the axis, thereby affecting the reliability of the compressor. [0003] The function of the crankshaft is to transmit the power of the rotor to the pump body. The crankshaft needs sufficient rigidity. The casting needs wall thickness to increase the strength and prevent the deflection and deformation from increasing the bearing wear. We...
