Abstract

A crown gear engine is created which differs from conventional combustion engines in the method of output power transmission in that for each piston (8) crank cheeks (6a) are provided, which engage with a crown gear (4), which transmits the output directly to an output shaft (3). <IMAGE>

Description

Pulley motor

The Erfirldglg relates to a pulley motor, which is a conventional Combustion engine with a new type of drive. The conventional internal combustion engines in the form of two-stroke and four-stroke engines transmit the explosive forces of the burning Gas mixture by means of the reciprocating piston via the connecting rod to the Crankshaft driving an output shaft perpendicular to the direction of movement the piston or the connecting rod runs. The drive shaft is then in most cases via a mechanical or automatic gearbox for the purpose of corresponding reduction tied together.

For example, in the field of ship propulsion systems, it is useful to to have a high torque at low revs. The same is it is expedient to change the dimensions of the arrangement of the internal combustion engine and output to keep it low.

A toothed disk motor that meets such requirements is now characterized in that the crankshafts have external toothed crank webs are in engagement with a toothed pulley, which is firmly connected to the main output shaft is.

The advantages that can be achieved according to the invention are in particular to be found therein see that e.g. in an engine with eight cylinders and with double firing order pro Revolution is the piston load compared to a conventional engine with eight cylinders is significantly reduced with the same engine power, i. the engine runs smoother, and the bearings are less stressed.

Due to the firing order, the engine is also more knock-resistant. If you go from an engine with twelve cylinders and with a triple firing order results in a comparative way to a rotor with twelve cylinders of conventional design and the same engine power, that there is a substantial advantageous change in the piston load. as The direct consequence of this is that the friction occurring in the engine is significantly reduced, do that there is an increased door of life of the same.

In the special field of propulsion systems for ships, the Advantage of a relatively high torque at low revs due to the transmission ratio between the crank webs and the pulley. Because of Due to its compact design, the pulley motor can be horizontal, inclined or vertical for installation.

The subject matter of the invention is briefly described below, for example Reference to the attached figures is explained as follows: Fig. 1 is a vertical one Cross section through the toothed disk motor; Fig. 2 is a plan view of the cam disk with the inlet cam.

The engine works according to your 4 '2-stroke system.

The engine block (1) has several (e.g. 5) cylinder bores arranged in a circle (2). The main shaft () runs through the middle, on which a toothed pulley (4) and on the The flywheel (5) is firmly attached to the shaft end.

Each cylinder (2) has its own crankshaft (6), the outer one Crank webs (6a) are toothed. When the starter (7) turns on the flywheel (5), the toothed disc (4) is rotated at the same time, which in turn engages with the toothed crank webs (6a) and thus the piston (8) moves up and down will.

Each crankshaft (6) makes two full turns with one main shaft revolution Revolutions.

When a piston (8) is drawn in, it compresses and the cylinder (2) ignites the expanding explosion gases push the piston (8) in front of them.

The crankshaft (6) rotates with the toothed crank web (6a) toothed washer (4) engaged with it.

With the upward movement of the piston (8) the burned gases are released pushed past the open outlet valve (9) into the outlet channel (10). The sequence starts all over again.

A cam disk (11) is firmly attached to the start of the main shaft, which has a fixed exhaust cam (11a) and a variable intake cam (11b) in order to achieve an optimal cylinder filling at every speed.

The cam disk (11) drives two valves (9, 9a) per cylinder.

The distributor (12) is also controlled by the main shaft (3).

Water pump (13), oil pump (14) and alternator (15) are through a secondary shaft (16) controlled by the main shaft (3) is driven.
