The present invention encompasses a transmission arrangement (1 ) for translating a reciprocating translation movement, related to each of two gea r rods (51 , 52), in mesh with its allotted gear wheel (10', 11 '), where a first gear rod and its associated first gear wheel (10') is representing a first prime motor arrangement (10), while a second gear rod and its associat ed second gear wheel (11 ') is representing a second prime motor arrangement (1 1 ), including its related freewheel bearing (7, 8). A gear wheel arrangement (4, 5, 6), including bevel gear wheels, is adapted to expose a first bevel gear wheel (4) in cooperation with said first gear wheel (10'), a second bev el gear wheel (6) in cooperation with said second gear wheel (11 ') and a third bevel gear wheel (5) adapted to mesh with said first and second gear wheels (4, 6), in order to adapt or to cause these first and second bevel gear whee ls (4, 6) in different rotational directions. Said first bevel gear wheel (4) a nd its associated first gear wheel (10'), related to said first prime motor arrangement (10), are integrally formed as to form one first unit (100). Sai d second bevel gear wheel (6) and its associated second gear wheel (11 '), related to said second prime motor arrangement (11 ), are integrally formed as to form onesecond unit (200). Said first unit (100) and said second unit (200) are, via its related freewheel bearing (7, 8), pivotally supported by said shaft (2) at a first pivotal direction and fixedly or blockingly supported by said shaft (2) in an opposite second pivotal direction. Said first (100) and second (200) units are identically formed. |
