Abstract

The invention discloses an elastic damping support for a motor rotor of an ultracentrifuge, which comprises the structures of O-shaped rubber rings, a high-speed bearing, a supporting seat, the motor rotor, a motor stator and a motor shell, wherein the outer sides of the high-speed bearing at two ends of the rotor are provided with O-shaped rubber ring bases, and the O-shaped rubber rings are arranged between the supporting seat and the O-shaped rubber ring bases. The elastic damping support overcomes the defects that a domestic product has low precision, easy heat generation and short service life, and simultaneously solves the manufacturing difficulty of using metal rings in foreign countries; besides, the operation of the elastic damping support is better than the motor with the foreign metal rings, and the elastic damping support replaces the import and widens the international market.

Description

1. Technical field: [0001] The invention discloses an elastic damping support for a motor rotor of an ultra-speed centrifuge, which relates to the technical field of design and manufacture of high-speed centrifuges, in particular to the technical field of design and manufacture of motors for high-speed centrifuges. 2. Background technology: [0002] Centrifuge technology is an indispensable technology in the research of molecular biology and biochemistry. It is the centrifugal force field generated by the high-speed rotation of the centrifuge according to the difference in the sedimentation coefficient and buoyancy of the substance. Make the object do the sedimentation movement, so that the substances of different densities and molecular weights in the substance can be separated, concentrated, purified and identified. The basic equipment of centrifugal technology can be roughly divided into three types. Ordinary centrifuges are below 10,000 rpm; high-speed centrifuges have ...
