RU2329180C1 - Wheel-and-blade propulsive device - Google Patents

Abstract

FIELD: transportation.

SUBSTANCE: wheel-and-blade propulsive device incorporates three identical wheels. The blades are fitted between the first and second wheels on parallel crankshaft axles. The crankshafts are arranged between the second and third wheels. Additional blades are fitted between the third and additional fourth wheel on additional crankshaft axles. Centers of all four wheels are linked by one fixed crank axle.

EFFECT: simpler design and higher efficiency.

Description

Technical field

The invention relates to propulsors for water and land transport.

State of the art

Known blade propeller according to patent RU No. 225278 C1. However, the parallel-moving blades of this propeller are mounted on misaligned axles, which leads to large loads on the bearings.

A closer solution is patent FR No. 615061, class. B63H 1/04. The prototype includes three identical wheels. Between the first and second wheels are parallel moving blades, and between the second and third - crankshafts. The main disadvantage of the prototype is a large number of wheels and crankshafs, normalized (per) on one blade of the mover.

Disclosure of invention

In order to eliminate this drawback, the proposed propulsion device contains four identical wheels connected by a fixed crankshaft and crankshafts located between the second and third wheels. On the axes of the crankshafts between the first and second wheels, as well as between the third and fourth wheels, the blades are motionlessly fixed. Two double-sided segments can be installed on the crankshaft between the blades, and more than one blade can be installed on each crankshaft axis.

The proposed technical solution is illustrated by drawings, where:

figure 1 schematically shows a view of the device;

figure 2 shows the wheel-blade tract;

figa, 3b and 3c - options for the location of two or more blades mounted on the same axis of the crankshaft.

The device contains:

1 - crankshaft axis, 2 - wheel, 3 - crankshaft, 4 - crankshaft axis, 5 - blade, 6 - double-sided segment, 7 - drive gear (fixed to the wheel) and 8 - scraper.

The work of the wheel-blade propulsion is as follows.

The drive from the engine is transmitted to the wheel 2 through the gear 7. The wheels begin to rotate, and the blades 5 move in a circle, remaining parallel. The double-sided segment 6 performs two functions: 1 - at high speeds it reduces the disturbance of the medium and 2 - together with the scrapers 8, it cleans the soil adhering to the blades.

To increase the thrust of the propulsion device, for example, a triple blade can be used (see figa). To reduce the pressure on the ground, you can use the blade of fig.3b. And to create a lifting force when moving through water, the blade of FIG. 3c can be used.

Claims (3)

1. Wheel-blade propeller containing three identical wheels, blades are installed between the first and second wheels on the parallel axles of the crankshafts, crankshafts are installed between the second and third wheels, characterized in that between the third and additional, fourth, wheels on the additional axles of the crankshafts blades, while the centers of all four mover wheels are connected by one fixed crankshaft. 2. The device according to claim 1, characterized in that on the crankshaft axis between the blades are two double-sided segments. 3. The device according to claim 1, characterized in that at least two blades are installed on the crankshaft axis.
