Description

Blade propellers, which can also serve as engines with blades, are already known. mounted obliquely to the axis forcibly along the EI of a shaft located perpendicular to the axis of the drive shaft and rotated around this latter.

The disadvantages of the known constructions of such engines are the difficulty of quickly changing the front stop to the rear to obtain any mode of propulsion operation.

The proposed propeller eliminates the noted drawbacks and has the peculiarity that for forcibly turning the shaft with blades relative to its own longitudinal axis, a pin is fixed on it, which is connected by a joint with a thrust; the rearrangement of the latter causes a turn, and together with these changes the angle of attack of the seed. blades on keM.

In FIG. Figure 1 shows schematically a longitudinal section of an exemplary form of driving spacing; FIG. 2 illustrates the installation of a propulsion unit under the ship’s feed, and FIG. 3 shows a four-bladed propulsion circuit.

The propeller consists of two blades / rigidly mounted obliquely to maintain the required angle of attack with respect to the medium at the ends of the shaft 10. For forcibly turning the shaft 10 relative to its own longitudinal axis. The pin 13, transverse to it, is fastened to it, the ends of which are passed through the liners plug 12, equipped with 8 middle part of the trunnion 4. Pin- # of the fork 12 is equipped with a adjustable sleeve bushing 9 with a hinge 14 connected by a fork 15 with a lifting and lowering rod 3 of the device that controls the rotation of the blades. The rod 3 can move along the pipe 8. being mated with it by a key 17. The pipe 8 can rotate from the spindle shaft 7 of the control, and the rod 3 moves along the pipe 8 with the help of the spindle wheel 19 through an appropriate gear //, 18. The shaft 10 is mounted in rotor bearings 2, passing into the hollow shaft 5 associated with the motor 6 by a bevel gear 16.

When the hollow shaft 5 rotates, the shaft 10 with blades / rotates around a vertical axis and rotates around a horizontal

the axes so that the blades / change the angle of attack, even to zero in two positions for each revolution of the hollow shaft 5,

As a result of the interaction of the blades 1 with the medium, an abutment force develops, which is directed at a hundred: distance of movement. By moving the rod 3 from the handwheel 19, it is possible to force the shaft 10 with blades / rotate by an angle of attack equal to zero during the HOLE1 stroke, and change the angle of attack for the desired propulsive mode of operation, i.e. forcing the propulsor to work at the greatest coefficient of useful action.

Turning the pipe 8 from the handwheel 7 together with the rod 3, you can get any direction of the stop. By virtue of the foregoing, the steering device becomes redundant.

The tube 8 encloses the hollow shaft 5. outside, and the handwheel 19 is screwed onto the tube 8. Rod 3 can HiMieTb pointer 20 for reading the angle of attack on a scale of 21.

The return stroke can be obtained without skidding the vessel to the side, for which it is necessary to translate the angle of attack of the blades first and the zero value, and then turn the blades 7 of the blade backwards with the desired angle of attack.

FIG. 2, the tube 8 is missed inside the hollow shaft 5. To move the rod 5 from the handwheel 19, a flexible shaft 11 and a screw 5 are designed for 18. A rod 5 which engages with the rail.

The propeller can work both in the submerged and in the submerged state, and is suitable for right and left rotation. The blades may have a wing profile.

In the case of a four-bladed drive, both transverse trunnions / 5, 13 shafts of paired blades are pivotally connected with rod 3 (Fig. 3).

Thing. invented and

Blade propulsion for liquid and gaseous medium, which can also serve as a motor1, in which the blades are located forcibly rotating the shaft, located perpendicular to the axis of the drive shaft and rotating around this latter, characterized in that for forcing the shaft with blades relative to its own longitudinal The axle on the latter is reinforced by a trunnion 13, which is jointed with a hinge joint to the lifting and lowering rod 5 of the device that controls the rotation of the blades.
