Problems solved by technology

Its disadvantage is that, after prolonged operation of the device, this seal will become leaky and the lubricant will escape under the action of the prevailing centrifugal and / or acceleration forces in the region of the seal
This can damage the gear unit and also cause the inside of the centrifuge to become contaminated with lubricant
This problem arises in particular when the bearings get hot, which limits the operating time of the device to a maximum of 30 minutes

Embodiment Construction

[0101] figure 1 The view in FIG. 2 shows a double centrifuge 10 for homogenization and separation of media, which comprises a centrifuge motor 12 and a centrifuge rotor 14 . The centrifuge rotor 14 rotates about an axis A corresponding to the drive shaft of the centrifuge motor 12 . The centrifuge rotor 14 is connected to a rotation unit 16 mounted rotatably about rotation axes R1 , R2 of the rotation unit. The rotary units 16 have on their peripheral parts gear teeth 18 which mesh with a gear 22 which is non-rotatably mounted on the centrifuge motor housing 20 . Rotation of the centrifuge rotor 14 relative to the motor 12 about the motor axis A will cause the rotation units 16 to rotate about their rotation unit axes R. FIG. Each rotating unit 16 is mounted in a recess 30 in the centrifuge rotor 14 which is provided in the centrifuge rotor 14 specifically for the purpose of mounting the rotating unit, each rotating unit 16 being inserted into two bearings 24 , 26 (the two ...

Abstract

The invention relates to an apparatus for homogenization and separation of media (10), comprising a centrifuge (40, 70) having a centrifuge rotor (14, 44, 74) which is rotatable about a motor axis (A) of a centrifuge motor (12, 42, 72) and has a rotor body to which at least one rotation unit (16, 48, 80) is connected such that the latter is additionally configured so as to be rotatable about a rotation unit axis of rotation different from the motor axis (A), and this rotation unit can be driven by means of a rotation unit drive, with provision of means by which at least two different speeds of rotation of the rotation unit (16, 48, 80) can be set, and the rotation unit (16, 48, 80) is also provided in its peripheral region with a tooth system (8) by which the rotation unit (16, 48, 80) can be driven. It is a feature of the invention that the rotation unit drive has a tooth system associated with the centrifuge motor.

Description

technical field [0001] The invention relates to a device for dual centrifugation of samples. Background technique [0002] Double centrifugation (DC) is a process in which a sample is rotated around a primary axis of rotation at the same time as a secondary axis of rotation, so that the secondary axis of rotation can intersect the sample at any point and can also be outside the sample. [0003] For this reason, in addition to the main axis of rotation, the double centrifuge device also comprises at least one additional axis of rotation, ie a secondary axis of rotation about which the sample can be rotated. Typically, the device for receiving and holding a sample (sample holder) rotates about a secondary axis of rotation. [0004] A process performed using a double centrifuge device, ie utilizing the interaction of two rotational movements, is called a double centrifuge process (DC process). This process can be performed more efficiently than conventional processes due to t...
