Embodiment Construction

[0036] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] see Figure 1 to Figure 3 , taking the crankshaft of the present invention including two eccentricity adjustment devices 120 as an example, the crankshaft of the present invention will be described. Wherein, the crankshaft includes a crankshaft body 110 and an eccentric portion disposed on the crankshaft body 110 . The eccentric part includes two eccentric adjustment devices 120 . Meanwhile, the crankshaft body 110 is provided with two mounting holes 111 distributed along the circumferential direction. It should be noted here that the installation holes 111 correspond to the eccentricity adjustment devices 120 one by one.

[0038] Wherein, the eccentricity adjusting device 120 is provided with a connecting portion 121 , and is inserted into the mountin...

Abstract

The invention discloses a crankshaft and a compressor with the same. The crankshaft comprises a crankshaft body and an eccentric part, wherein the eccentric part is arranged on the crankshaft body; more than two circumferentially distributed mounting holes are formed in the crankshaft body; the eccentric part comprises more than two eccentricity adjusting devices; a connection part is arranged on each eccentricity adjusting device, the eccentricity adjusting devices are connected with the crankshaft body after the connection parts are inserted into the mounting holes, and the eccentricity adjusting devices are suitable for moving in a radial direction of the crankshaft body. When the crankshaft rotates, the vector sum of a rotation inertia force of a roller sleeving the exterior of the eccentric part and a rotation inertia force of each eccentricity adjusting device is equal to zero. Therefore, the problems that the existing compressor crankshaft assembly technique is complex and the universality of the compressor crankshaft is reduced are effectively solved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a crankshaft and a compressor with the crankshaft. Background technique [0002] At present, due to the existence of an eccentric circle on the crankshaft of the compressor, the center of mass of the eccentric part of the crankshaft and the roller does not coincide with the rotation center of the main shaft, so a rotational inertial force will be generated during the operation of the compressor. Usually, the balance of the rotational inertial force is achieved by adding the main and auxiliary balance weights of the motor, and the cooperation between the main and auxiliary balance weights and the eccentric part of the crankshaft. However, the cooperation between the main and auxiliary balance weights and the eccentric part of the crankshaft cannot achieve a complete balance of the rotational inertial force, and the imbalance of the rotational inertial force will increase the winding deg...
