Abstract: In a mechanical gear transmission, a leaked lubricant liquid, used to lubricate an external ring gear meshing with at least one internal gear wheel, is collected and reintroduced in the system by means of a manifold having a first concave portion, which has a concavity facing towards the external ring gear, so as to house a mass of liquid moved outwards as a result of a centrifugal effect, and at least a second concave portion, which is designed to receive the leaked liquid and has a concavity facing towards the first concave portion; channelling walls being provided to channel the leaked liquid towards one or the other concave portion.

Abstract: A filtering net, in particular for a rotary separator, has a plurality of cells, which are substantially equal to one another and are defined by the replication of a base cell along two transversal directions of replication; the base cell comprises at least one intermediate filament and a first and a second end filament, arranged on opposite sides of the intermediate filament; the intermediate filament and the end filaments extend along respective longitudinal axes which are parallel; cross-sectioning the base cell with any plane orthogonal to the longitudinal axes of the filaments and joining, on said plane, the trace of each longitudinal axis with the trace of the adjacent longitudinal axis by a respective straight line, the two straight lines are incident at the trace of the longitudinal axis of the intermediate filament and form an incidence angle of between approximately 90° and 160°.

Abstract: A filtering body, in particular for a rotary separator, extends about an axis and has a two opposite axial faces, a radially outer surface and a radially inner surface; the filtering body comprises a filtering net constituted by filaments defining a plurality of pores between them; a frame, which is defined by non-porous solid elements, supports the filtering net and made in one piece with a filtering net; the frame has at least one element arranged in an intermediate radial position between the radially outer and inner surfaces.
