Design concepts of propulsion systems
22
V-drive, various types
Close coupled V-drive
The engine and reverse gear form one unit. The axial
forces from the propeller are absorbed by an axial
bearing in the reverse gear.
Remote V-drive
The reverse gear is separated from the engine and
mounted on a separate bed. Torque is transferred via
the propeller shaft, as illustrated in the diagram, or
via a flexible coupling.
The axial forces from the propeller are absorbed by
an axial bearing in the reverse gear.
The remote V-drive must first be installed and care-
fully aligned according to the propeller shaft. Then
the shaft and couplings are fitted and the engine is
aligned to the reverse gear. For final location and to
prevent possible shock loads, lugs must be welded in
front of and behind the brackets on each side. Wedg-
es are then driven in and secured by welding when
alignment is completely finished.
For the application of cardan shafts, follow the instal-
lation instructions from the cardan shaft supplier. A
rule of thumb share the joint angle, where A
≈
A.
