Abstract: A device for transmission of rotary motion and transfer of a fluid medium, comprising a planetary gear train for transmission of rotary motion about a main axis which has at least one reduction stage which is provided with a sun gear, which rotates about the main axis, and a toothed ring gear which are mutually concentric and between which at least two planetary gears are engaged which are supported in rotation at least about the respective longitudinal axes which are parallel to the main axis by a planetary gear carrier; such planetary gear train is provided with a driving input sun gear and with an output ring gear and with an output planetary gear carrier, of which one can move in rotation about the main axis with respect to the other; and a rotary joint which extends externally to the planetary gear train for transfer of the fluid medium.

Abstract: A connect and disconnect assembly may have a first rotatable shaft and a second rotatable shaft aligned along a rotational axis. The assembly may also have a connect and disconnect device including one or more cams for selectively connecting and disconnecting the first rotatable shaft to and from the second rotatable shaft. A ship-lift bogie may include the connect and disconnect assembly.

Abstract: A reciprocating pump drive is disclosed. The reciprocating pump drive comprises a housing and a transmission mechanism. The transmission mechanism comprising an input shaft rotatably supported in the housing. The input shaft has an input shaft axis. An intermediate shaft is rotatably supported in the housing and coupled to the input shaft. The intermediate shaft has an intermediate shaft axis wherein the input shaft axis is parallel to the intermediate shaft axis. A gear assembly is coupled to the intermediate shaft. An output shaft is coupled to the gear assembly. The output shaft has an output shaft axis wherein the intermediate shaft axis is coaxially aligned to the output shaft axis.
