Definitions

• Control device and boat drive with control device
• the invention relates to a control device according to the preamble of claim 1 and a Bootsa ⁇ trieb according to the preamble of patent claim ' Che 2,
• control devices which include a servo or electric motor and a nachg ⁇ schaitetes gear reduction gear for adjusting a Stellglie-, often have the problem that in the transmission of the steep movement Spie! occurs, in particular a Fiankenspiel between the meshing gears. This causes the actuator in its set position, d. H. is not stable when detected steep motor.
• Such control devices are also used in boat drives, soft one by one
• WO 2005/005249 has disclosed an inboard propeller drive for a boat, wherein a propulsion unit, comprising a propeller shaft with two opposite train propellers and an underwater housing, is arranged pivotably about a vertical axis in the boat hull.
• the control effect of the boat is thus not - as usual - by a rudder, but by pivoting the Vortriebs ⁇
• the drive-side gearwheel is simultaneously driven by two servomotors, which work slightly against each other.
• Wig also solved in a control device according to the invention with two jointly driving, slightly counteracting servomotors.
• the advantage of this zero-clearance control for a boat propulsion system is that a stable "rudder position", ie a stable position of the propulsion thrust vector sets in. The boat thus runs exactly on course, and the helmsman has the feeling at the steering wheel that the movements of the steering wheel directly In
• the two servomotors are each designed as electric motors, d. H. They draw their energy from the electrical system, are easily controlled and electronically controlled,
• the speed of the two servomotors or electric motors is in each case reduced by a first planetary gear in a first stage, wherein the output of the two first planetary gear each carried out via a drive pinion.
• a second PI ⁇ hest provided.
• a third gear reduction stage is provided in which the output side Son ⁇ enrad the second planetary gear engages in an outer toothing of the control sleeve, which in turn is connected to the underwater housing,
• the Vortri erritt with the control device is flexibly guided through a hull intermediate piece, which is firmly connected to the boat hull.
• the and control unit vertical vibration movements, due to storage in the fuselage run.
• the fuselage spacer is designed in sandwich construction. This can gie in case of collision
• Fig. 1 is a partially illustrated Bootsa ⁇ trieb with control device
• Flg. 1 shows a partially illustrated boat drive 1 with a propulsion and control unit pivotable about a vertical axis z (vertical axis), partially shown here by an underwater housing 2.
• the aerodynamically formed underwater housing 2 carries one or two counter-rotating propeller not shown (also called screws), which are driven by a drive shaft 3 of a not shown, arranged in the boat hull internal combustion engine.
• the Antriebswelüe 3 is the engine side via a bevel gear 4 (part of a bevel gear stage) driven and drives in turn via a not shown bevel gear not shown PropellerweSle or the Propeüerwefen.
• the first planetary gear has a drive pinion 9, which drives a pinion carrier 10 of a second pinion 11, that is to say a pinion. H. with this engaged with teeth.
• the driven planet carrier 10 has been charged to planet pins 12 and each with a fixed
• Sun gear 14 and a sun gear 15 are in meshing.
• the fixed sun gear 14 driving sun gear 15 engages se 17, soft ge in axial Direction is fixed.
• the control sleeve 17 is rotatably connected to the underwater housing 2.
• the gear stage between the sun gear 15 and the transmission sleeve 17 is a third reduction stage. Overall, the reduction from the motor drive line 6a via three reduction stages totals approximately 1: 1000.
• the boat drive 1, in particular the gear housing 18 passes through an opening of a fuselage intermediate piece 19 and forms with this a Rsngspaft 20 which is bridged by flexible sealing elements 21 and thus sealed.
• the hull adapter 19 is made in sandwich construction and as Crashtei! formed, which is firmly connected to the boat hull, not shown.
• Fig. 2 shows a view in the axial direction of the planet carrier 10 of FIG. 1, softer with two drive pinions, the first drive pinion! 9 (see, Fig. 1) and a second A ⁇ triebsritzel 22 is in meshing engagement.
• the second drive pinion 22 is like the first drive!
• the planet carrier 10 is driven jointly by the two A ⁇ friebsritzel ⁇ 9, 22, but both drive pinion 9, 22 slightly against each other work, so a backlash is eliminated with the external toothing of Planete ⁇ ckens 10.
• the planetary carrier 10 (also planetary carrier) is thus "clamped" clearance-free between the two drive pinions n 9, 22.
