Definitions

  • the invention relates to a ship, the drive shaft of which projects through a bearing bush solidly joined to the stern post, on which bush a propelling screw is mounted, the end of the drive shaft being joined by a coupling piece to the hub of the said propelling screw, all this in a manner such that the thrust is transmitted to the stern post via the bearing bush.
  • Said construction has the disadvantages that a gear box, which is neces­sary to convert the torque delivered by the motor into two dissimilar rotary motions, is complicated, while the mounting and sealing of rotating shafts projecting into each other is associated with considerable problems.
  • the mounting problem is a consequence of the fact that no film of lubricant can build up.
  • the object of the invention is to eliminate the problems outlined in the case of different screws which have to be able to rotate in opposite directions and/or at different speeds.
  • the ship specified in the introduction is characterized for this purpose in that two or more separate screws are mounted on the bear­ing bush solidly joined to the stern post and a trans­mission system is provided between the hubs of the screws which links the hubs in a drive mode to each other.
  • Lubrication and bearing can take place easily in a conventional way.
  • the use of two or more separate screws has the advantage that the mutual blade position can be chosen in a manner such that vibrations due to propellor surges are limited to a minimum and beat phenomena are eliminated.
  • the transmission consists of a plan­etary gear box.
  • gear rings On each of the hubs, at the sides thereof facing each other, two gear rings may be provided: an innermost ring, the teeth of which face outwards, and an outermost ring the teeth of which face inwards.
  • a series of shafts may be placed with a pinion at both ends, the one pinion of each shaft engaging in the inner­most gear ring of the one hub and the other pinion in the outermost gearing of the other hub and, seen in the cir­cumferential direction of each of the gear rings, a pinion engaging in the innermost tooth system always alternates with a pinion engaging in the outermost tooth system, con­secutive pinions being staggered in the axial direction.
  • Michell blocks consisting of a ring of small pressure blocks which are able to tilt slightly and can adjust themselves automatically if the axial pressure alters (Michell blocks are described, inter alia, in "Machine­onderdelen" (Machine components) by Ir G. Hofstede, Ir H.J. Meeuwis and Ir P.G. Ridderhaus, 1953, pages 114 and 201).
  • the transmission may also consist of a hydraulic clutch.
  • the transmission can be given an embodiment such that the screws will rotate in opposite directions. In such the case of another possibility the screws may rotate in the same direction at unequal speed.
  • the screws may also have an unequal pitch.
  • the propelling screw 1 with hub 2 is rotatably mounted on a bearing bush 4 via bearings 3 which absorb axial load and bearings 13, 14 which absorb radial load, which bearing bush 4 is joined to a part 5 of the stern post of the ship, for example a block load.
  • a second propelling screw 15 with hub 16 is rotatably mounted on the same bearing bush 4 via bearings 3' which absorb axial load and bearings 13', 14' which absorb radial load.
  • the hubs 2 and 16 are secured by a nut 9 screwed onto the bearing bush 4, a pressure ring 10 being placed between the nut and the hub 2.
  • a coupling piece 11 is mounted on the end of the shaft 6, which end is provided with axial grooves, bolts 12 serving to bring about a link between said coupling piece 11 and the hub 2.
  • the bearings 3, 3' which absorb axial load each form a so-called Michell block, that is to say that they comprise a series of small pressure blocks arranged in a circle which can adjust themselves automatically because they can tip or tilt if the axial pressure changes. Be­cause the small blocks can rotate slightly over the pres­sure face a complete lubrication is produced, which would not be possible between parallel sliding surfaces.
  • the radial bearings are sliding bearings and comprise a bear­ing bush 13 or 13' respectively mounted on the bearing bush 4 and a bearing bush 14 or 14' respectively which can be rotated about it and is attached to the hub 2.
  • the fixed part of the bearings 3, 3' and the bearing bush 13, 13' are trapped between the stern post part 5 and the ring 8 on the one hand, and the nut 9 and the ring 10 on the other hand.
  • a transmission system 17 to be described in more detail is placed between the two hubs 2 and 16.
  • the transmission system 17 is a planetary gear box provided with a series of shafts 18 of the same length which are arranged as a cylinder and which are mounted in the block 19 which is trapped on the bearing bush 4.
  • a relatively small pinion 20 is provided at the one end of each shaft and a somewhat larger pinion 21 is provided at the other end. Seen in the circumferential direction of a series of pinions, pinions 20 and 21 al­ternate with each other. Each of the smaller pinions 20 engages in one of the innermost gear rings 22, 23 which are provided in a recess of the hubs 2 or 16 respectively with the teeth facing outwards. Each of the larger pin­ions 21 engages in one of the outermost gear rings 24, 25 which are provided in one of the said recesses in the hubs 2 or 16 respectively with the teeth facing inwards.
  • the hub 16 of the screw 15 is rotated in the opposite direction, the power from the hub 2 being transmitted in a well distributed manner to the nut 10. Because of the relatively large number of pinions the transmission sys­tem 17 has a compact construction.
  • the vibration generated by propellor pulses can be limited to a minimum with a permanently chosen mutual blade position of the screw.
  • beat phenomena may occur through lack of synchronism; with the a priori synchronous drive of the screws 1 and 15 according to the invention this pos­sibility is ruled out.
  • the construction ac­cording to the invention has the advantage that the bear­ing, in particular the lubrication of the hubs, presents no problem.
  • the planetary gear trans­mission system is also simpler in construction than a gear transmission system for two concentric shafts.
  • a planetary gear transmission sys­tem between the hubs 2 and 16 is not a necessity.
  • Another possibility for the transmission system 17 is a hydraulic clutch which reverses the direction of rotation.
  • Such a clutch which is known per se, comprises, for example, a ring of blades attached to the hub 2 which, with the hub rotating, generates a liquid flow which sets in motion a second ring of blades which is attached to the hub 16.
  • screw hubs may also be mounted behind each other on a fixed bearing bush within which the drive shaft extends which drives the rearmost hub via a coupling piece, a planetary gear transmission system or a hydraulic clutch always being placed between successive hubs.
