ABSTRACT:
The drive of a centrifuge utilized in biology, biophysics and medicine includes a casing accommodating a stator and a rotor whose shaft is installed in an angular bearing and rigidly connected with a flexible shaft fixed rotatably in a dumping device. The casing has passages for the circulation of lubricant and coolant, respectively, the rotor has a blind hole arranged coaxially with the rotation axis of the rotor; and the angular bearing has supporting and radial slide surfaces and is fixed in the rotor by means of the damping device so that the radial slide surface is located at least partly in the blind hole of the rotor, said bearing having passages ensuring circulation of lubricant over its supporting and radial surfaces.
