SEPARATOR WITH DIRECT DRIVE Russian patent published in 2013 - IPC B04B9/04 

FIELD: process engineering.

SUBSTANCE: separator comprises centrifuge drum with vertical rotational axis D and material feed line, centrifuge drum drive spindle running in bearing assembly fitted in housing elastically resting on bed, and drive device with drive motor composed of stator and rotor aligned with drive spindle. In operation drive device integrated with motor housing into single oscillating assembly moves with drive spindle. Drive device is coupled with bed by, at least, one or several connection elements under bearing assembly, in particular, at its bottom axial end. Said connection elements are composed of a flat part from metal sheet directed, as-mounted, perpendicular to rotational axis D. Note here that said connection elements or element feature lower stiffness in axial vertical direction compared with that in radial direction relative to said axis D.

EFFECT: decreased radial play, longer life, reduced noise.
