Abstract: A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.

Abstract: A drum and ring gear assembly for winches with geared transmission which comprises a substantially cylindrical drum adapted to be actuated rotationally about its own longitudinal axis and a ring gear accommodated substantially coaxially inside the drum, which are mutually associated so as to rotate integrally about the longitudinal axis by virtue of connecting means; the connecting means is of the positive and/or direct friction type.
