Abstract

The invention relates to the technical field of medical facilities, in particular to a rotor assembly of a centrifugal machine. The rotor assembly comprises a drive shaft and a rotor connected with a drive motor. A positioning key is arranged at the circumferential surface of the drive shaft; a fixed bolt is arranged at the end part of the drive shaft; the rotor is in a circular shape; a connecting hole is formed in a circle center part of the rotor; the drive shaft penetrates through the connecting hole; the rotor is fixed onto the drive shaft through the positioning key and the fixed bolt; and a plurality of centrifugal pipe inserting holes are formed in the rotor and are distributed symmetrically relative to the circular center of the rotor. According to the rotor assembly of the centrifugal machine and a processing method thereof, the structure design of the product is reasonable, and especially during a processing process, the drive shaft and the rotor are preprocessed, so that a mechanical strength performance and an anti-corrosion property of the rotor assembly are improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a rotor assembly of a centrifuge. Background technique [0002] A high-speed centrifuge is a device that uses centrifugal force to separate a liquid phase inhomogeneous system. According to the sedimentation coefficient, mass, density, etc. of the substance, it uses a powerful centrifugal force to separate, concentrate and purify the substance. Centrifuges are widely used in biological and medical fields, such as blood separation, virus research, DNA research, drug purification, etc. are widely used in centrifuges. Due to its complex structure, traditional medical centrifuges are prone to noise during use, which affects the surrounding environment. [0003] In addition, the centrifugal assembly of the existing centrifuge also has defects such as poor corrosion resistance and poor mechanical strength. Contents of the invention [0004] The technical problem to be sol...
