Definitions

  • the invention relates to a boat drive with an adjustable propeller
  • the Hub can be attached to a hollow propeller shaft coupled to a drive is and its propeller blades adjustable with an adjustment mechanism to which is arranged in the propeller shaft and on both sides above it heard extending plunger, one end of the plunger via a thrust bearing to a double-acting lifting cylinder connected in a housing of an outboard motor, a sterndrive or a shaft block is arranged.
  • Such a boat drive is known (DE 40 00 115 or US 5 073 134).
  • the hollow propeller shaft is driven by a bevel gear and is supported on a thrust bearing that receives the propeller thrust.
  • the adjusting plunger rotating with the hollow propeller shaft is through the thrust bearing passed through to a double-acting thrust bearing, on the on the other hand the non-rotating piston rod of the non-rotatable in the housing arranged lifting cylinder attacks.
  • the lifting cylinder is detachable Attachment of the housing. But this results in a relative large length of the underwater part with lifting cylinder, axial bearing, Bevel gear, propeller hub and possibly other components.
  • the object of the invention is to determine the overall length of the underwater part of the Reduce housing.
  • the lifting cylinder to the adjustment plunger has open hollow piston in which the thrust bearing is housed is. This saves the overall length required for the thrust bearing become.
  • the adjustment plunger can have a radial flange, which is supported on both sides by single-acting axial bearings.
  • a hollow piston rod advantageously adjoins the hollow piston, through which the adjustment plunger extends.
  • the piston rod should be axially displaceable and be rotatably mounted in the housing so that the piston rod and thus the hollow piston is not rotated by the rotating adjustment plunger become.
  • the housing can have a detachable housing cover.
  • the hollow piston can also have a detachable piston cover.
  • the thrust bearing can be closed and self-lubricating exhibit. But there is also the possibility of using a propeller shaft extending between a gear lubrication and the adjusting plunger Provide bore through which the gear oil due to the pressure drop reaches the axial bearing between rotating and non-rotating parts and serves there for lubrication and cooling.
  • a housing 1 of an outboard motor is indicated.
  • the Housing 1 has a drive shaft 2 with a bevel gear 3.
  • a bevel gear 4 is supported on a thrust bearing 5 and sits on a hollow propeller shaft 6, which is mounted in a housing insert 7.
  • On the propeller shaft 6 is next to the housing insert 7, a hub 8 of an adjustable propeller attached.
  • the hub 8 is rotatable on the circumference about radial axes arranged propeller blades 9, which by means of an adjusting mechanism 10 can be adjusted around their axes.
  • the adjustment mechanism 10 is on known, e.g. from DE 40 00 115, and therefore needs in detail not to be described.
  • Exhaust duct 11 runs parallel to drive shaft 2 in housing 1 Connect further channels in the hub 8 so that the exhaust gas Motor, not shown, can emerge on the free side of the hub 8.
  • the path of the exhaust gas is indicated by arrows 12.
  • the adjustment mechanism 10 includes an adjustment plunger 13 which is located within the hollow propeller shaft 6 is arranged and on both sides beyond it extends.
  • the left end of the adjusting plunger 13 in the figure is with the adjusting mechanism 10 connected.
  • the right end of the adjustment plunger in the figure 13 carries a radial flange 14 on both sides of single-acting Axial bearing 15 is supported.
  • the axial bearings 15 are in a hollow piston 16 arranged, the associated cylinder 17 inserted into the housing 1 is. Hydraulic lines 18 lead to the cylinder 17 Execution, the hydraulic lines 18 end on both sides of a piston seal 19 and the one to the right of the piston seal 19 in the figure Section of the hollow piston 16 has a slightly smaller outer diameter on as the section in the area of the piston seal 19.
  • a hollow piston rod is connected to the hollow piston 16 on the propeller shaft side 20 through which the adjustment plunger 13 extends.
  • the piston rod 20 is in the region of an axial flange adjoining the cylinder 17 21 provided with an anti-rotation device 22, which in the illustrated Version consists of keyways with associated keys.
  • the piston rod 20 and the associated hollow piston 16 are axial slidably but rotatably mounted in the cylinder 17 or in the housing 1.
  • the cylinder 17 has a detachable housing cover 23, over which a streamlined cover 25 extends.
  • the hollow piston 16 has a detachable piston cover 24.
  • the thrust bearing 15 can either be closed and self-lubricating or be supplied with gear oil via a between a gear lubrication and the adjusting plunger 13 extending bore 26 in the Propeller shaft are supplied with lubricant.
