PCT No. PCT/NO89/00039 Sec. 371 Date Nov. 27, 1989 Sec. 102(e) Date Nov. 27, 1989 PCT Filed Apr. 27, 1989 PCT Pub. No. WO89/10299 PCT Pub. Date Nov. 2, 1989.An arrangement in connection with an azimuth propeller for ships to measure the angle between the rotational axis of the propeller and the longitudinal axis of the ship (azimuth angle), and the angle of attack of the propeller blades. The azimuth propeller comprises a first housing (1) which is firmly connected with the ship, and a second housing (2) which is rotatably mounted in first housing (1). A first drive shaft (6) extends through the first housing and is connected with a drive shaft (11) of a propeller (13) with variable pitch blades (14), said drive shaft extending at an angle to the first drive shaft. A first rod (31) extends through propeller shaft (11) and is in connection with the propeller blades and is movable with them. To transmit the rod movement to a display means for the angle of attack of the propeller blades a tube (40) is provided to extend coaxially through first drive shaft (6) and is, via an arm system (33, 41, 42), connected with first rod (31), and for display of the azimuth angle a second rod (43) extends through tube (40) and is firmly connected with second housing (2). |
