In a second aspect of the present invention, marine propulsion unit 20 is stern driver, and it includes gear-box and extends and have the lower tooth roller box 30 of bottom 60 under water.Gear-box is via driving axle to be connected to electromotor, and with the angle of generally downward 90 degree, from electromotor, engine power is delivered to lower tooth roller box 30.Marine propulsion unit 20 is installed on the stern trimming flag of boats and ships 10 and pivots, to provide turning function.
In a third aspect of the present invention, marine propulsion unit 20 is gondola unit, is also referred to as azimuth thruster.Gondola unit includes hang oneself shipping bill unit and lower tooth roller box 30.Hang oneself shipping bill unit via driving axle to be connected to electromotor, and includes variator 50 and turning function.Lower tooth roller box 30 extends below at hull, and can rotate about 40 degree to larboard or starboard, to provide turning function.
Fig. 2 illustrates the lower tooth roller box 30 of marine propulsion unit 20.Lower tooth roller box 30 includes the pillar 40 extended below in water line 15.Lower tooth roller box 30 includes one or more driving axle 200, for engine power being delivered to propeller via at least one bevel gear set 270.Lower tooth roller box 30 also includes bearing 260, is used for supporting driving axle 200 and propeller shaft 205.Lower tooth roller box 30 forms the first volume 140 being filled with oil at least partly, is used for lubricating driving axle 200, propeller shaft 205, bevel gear set 270 and bearing 260.Lower tooth roller box 30 may also include oil pump 250.
Bottom 60 includes in nose section 100 above, in middle shaft segment 70 with in propeller section 90 below.Bottom 60 can be torpedo-shaped.Shaft segment 70 includes driving axle 200, is used for driving propeller shaft 205.If marine propulsion unit 20 includes rear screw shaft 230 and front propeller 240, then shaft segment 70 can include inner propeller shaft 210 and external spiral oar axle 220.Stern fin 190 could attach to the bottom of shaft segment 70.Stern fin 190 can be separate type.Circular hole 80 is included before shaft segment 70.The internal diameter of shaft segment 70 is formed with screw thread near hole 80, and is configured to by threadingly receiving mid portion 110.
Propeller section 90 is positioned at the rear portion place of bottom 60, and includes at least one propeller 225 driven by propeller shaft 205.Propeller shaft 205 is driven by bevel gear set 270, and bevel gear set 270 is driven by driving axle 200.In one aspect of the invention, propeller section 90 can include the rear screw shaft 230 driven by inner propeller shaft 210 and the front propeller 240 driven by external spiral oar axle 220.Inner propeller shaft 210 and external spiral oar axle 220 are driven by bevel gear set 270, and bevel gear set 270 is driven by driving axle 200.Both rear screw shaft 230 and front propeller 240 is used to increase the thrust provided by marine propulsion unit 20.Front propeller 240 can have three blades, and rear screw shaft 230 can have four blades.Rear screw shaft 230 can need less diameter due to the flow velocity at blade tip place.For making less rear screw shaft 230 have the blade area equal with front propeller 240, rear screw shaft 230 can have four blades rather than three blades.In another aspect of this invention, front propeller 240 can have four blades, and rear screw shaft 230 can have five blades.Propeller section 90 may also include propeller shaft anode 50.Propeller shaft anode can have maximization motive effect of fluid provides the parabolic shape of anticorrosive protection simultaneously.
Nose section 100 substantially bullet shaped, and be positioned at before bottom 60, and include mid portion 110 and nose cone 130.
Mid portion 110 is substantially frusto-conical, and includes the first bonding part on the external diameter of rear end and the second bonding part on front end external diameter.First bonding part is configured to engage with hole 80.First bonding part and the second bonding part can engage via press-fit engagement, can pass through fixing screw etc. and fix, or can be threaded connection with.If engaged as threaded, then mid portion 110 can include the threaded portion 170 on the external diameter of rear end and the threaded portion 170 on front end external diameter.Mid portion 110 also includes intermediate bulkhead 120.Intermediate bulkhead 120 forms the wall of fluid impermeable.Mid portion 110 collectively forms the second volume 150 together with intermediate bulkhead 120.Mid portion 110 is spilt by hole 80 for preventing oil contained in lower tooth roller box 30.The threaded portion 170 that threaded portion 170 on the rear end of mid portion 110 is configured to hole 80 engages.There is provided O 180 to seal when shaft segment 70 and mid portion 110 are combined together.
Nose cone 130 is substantially conical or bullet shaped, and limits third volume 160.Threaded portion 170 on the internal diameter of nose cone 130 is configured to engage with the threaded portion 170 on the front end of mid portion 110.There is provided O 180 to seal when nose cone 130 and mid portion 110 are combined together.
Industrial applicibility
Bottom 60 is positioned at the bottom place of lower tooth roller box 30, and extends in water and below the hull of boats and ships 10.Thus, bottom 60 is susceptible to the damage from immersed body such as rock or shoal.Nose section 100 before bottom 60 is particularly susceptible for damaging.Therefore, the nose section 100 of the present invention is configured with nose cone 130, and nose cone 130 can be replaced when being discharged from lower tooth roller box 30 by oil.
Impaired nose cone 130 can screw down from mid portion 110.When nose cone 130 is removed, intermediate bulkhead 120 is contained in the oil 35 in lower tooth roller box 30.
When nose cone 130 brutal fracture, intermediate bulkhead 120 is for being contained in the oil 35 in lower tooth roller box 30, in order to avoid oil 35 is being repaired and can revealed before being affected.The loss preventing oil 35 just prevents impaired nose cone 130 from causing badly damaged to the gear in lower tooth roller box 30 and bearing.Similarly, intermediate bulkhead 120 is used for preventing water from can invade gear-box 30 before being affected in reparation.Preventing water from immersing just prevents impaired nose cone 130 from causing badly damaged to the gear in lower tooth roller box 30 and bearing.
