car for at least two trees operators, particularly machine extruder bivite, with ability to operate with high force.

摘要

A machine with at least two working shafts (2,3), particularly a double-screw extruder machine, comprises associated with each shaft (2,3) a gear (4,5) rotated by a drive gear (12,13), coaxial to said shaft (2,3) and gear (4,5) by way of at least two idle gear wheels (32,33) acting on said gear (4,5) and disposed within the drive gear (12, 13). Each idle gear wheel (32,33) rotates about a shaft (36,37) supported by a support member (34,35) which is advantageously mobile in a plane orthogonal to the axis (W,K) of the shaft (2,3) and is disposed about this latter; between the drive gear (12,13) and idle gear wheels (32,33) there is provided a floating gear (26,27) to transmit the drive force of the drive gear (12,13) to said idle gear wheels (32,33).
