Fig. 1 to 5 show an embodiment of a high-strength centrifuge rotor according to the present invention, which comprises an inner liner 1 made of a metal material and a reinforcing body 2 wound around the outer periphery of the inner liner 1, wherein the reinforcing body 2 is made of an insulating material at a contact portion with the inner liner 1, a cavity 20 for separating a centrifugal sample is provided in the inner liner 1, a driving part 24 for connecting a rotation driving member (e.g., a motor, etc.) is provided at the lower part of the inner liner 1, and a mounting member 3 is provided at the upper part of the reinforcing body 2.
According to the high-strength centrifuge rotor, the lining body 1 made of metal materials is favorable for guaranteeing the working condition requirements of corrosion and abrasion resistant medical and biological product processing of the cavity 20, the reinforcement body 2 made of insulating materials is wound around the periphery of the lining body 1 made of metal materials, the overall strength of the rotor is increased, the deformation amount of the rotor during high-speed rotation is reduced, static electricity cannot be generated due to friction between the lining body 1 made of metal materials during winding of the insulating materials, static electricity corrosion is effectively avoided, meanwhile, the winding quality of the reinforcement body 2 is prevented from being influenced by static electricity, and the high-strength centrifuge rotor is simple in structure and reliable.
Further, in the present embodiment, the reinforcement 2 includes a first fiber layer 21 wound around the outer periphery of the inner liner 1 and a second fiber layer 22 wound around the outer periphery of the first fiber layer 21, and the first fiber layer 21 is made of an insulating material. The first fiber layer 21 can increase the strength of the inner liner 1, reduce the deformation amount at high-speed rotation, and prevent static electricity at winding; the second fibre layer 22 may then further increase the overall strength of the rotor, while the material selection of the second fibre layer 22 may be more flexible since it does not directly contact the inner liner 1.
Further, in the present embodiment, the prestress of the first fiber layer 21 is greater than the prestress of the second fiber layer 22. The prestress is increased when the first fiber layer 21 is wound, so that the deformation of the rotor caused by centrifugal force during high-speed rotation is further reduced, and meanwhile, the inner lining body 1 formed by the metal materials before and after high-temperature solidification is prevented from being subjected to thermal expansion and cooling shrinkage to cause debonding between the metal materials and the first fiber layer 21, and the structure is reasonable and effective.
As a preferred embodiment, the first fiber layer 21 is a glass fiber layer and the second fiber layer 22 is a carbon fiber layer. The rotor is integrally formed by compounding nonmetallic composite materials and metal materials, the rotor mass is greatly reduced, the rotor has smaller rotational inertia due to lighter mass, acceleration and deceleration time is reduced, centrifugal efficiency of the centrifugal machine is improved, load of a driving motor is reduced, service life of the motor is prolonged, and working noise of the centrifugal machine is greatly reduced. Structurally, the inner lining 1 of the inner metal material meets the working condition requirement of processing biological medicine products, the high-strength glass fiber layer of the middle layer effectively prevents electrochemical corrosion, the high-strength glass fiber winding for increasing the prestress avoids interlayer debonding caused by thermal expansion and cooling shrinkage of the rotor in the forming process, and the deformation of the rotor at high rotating speed is smaller, so that the fatigue resistance performance is superior to that of the traditional metal rotor when the circulating stress is loaded. The outer layer of wound continuous high performance carbon fibers provides a significant reinforcement of the strength of the rotor. Compared with the expensive rotor made of single metal material, the high-strength centrifuge rotor has cost advantages and industrialization prospect. Of course, in other embodiments, aramid fibers, basalt fibers, etc. may be used.
Further, in this embodiment, the first grain 11 is provided on the outer side of the inner liner 1.

The second lines 23 and the third lines 32 can be mechanically polished to form coarse lines or fine threads, which is beneficial to improving the composite effect between the reinforcement 2 and the mounting ring.
