Abstract

The device offered for conversion of reciprocating motion into rotary motion consists of a driving disk mounted instead of connecting rod traditionally used for transmitting force between the piston and the crankshaft. Such solution allows increasing the stroke of piston and lessening the total weight of unit. Both alternatives of employment of invention are characterized in that construction of internal combustion engine does not comprise the connecting rods. The first alternative of two-stroke engine (fig.1E) is a two-cylinder engine having one crankshaft (5) and one disk (1) for conversion of reciprocating motion, which is mounted inside of piston (3) and cylinder (4). The second alternative (fig.2) is engine having two crankshafts and two disks for conversion of reciprocating motion. Assembly of crankshafts together with the said disks is placed inside of an engine case the crankshafts being directed in vertical plane under condition of bilateral symmetry. One set of pistons (3) is located onto both disks of motion converter so that load is distributed uniformly on both crankshafts. Both suggested alternatives can be used also for production of four-stroke engines and Diesel engines having small modular dimensions and increased power.

Description

KUSTĪBĀ UN TĀS PIELIETOJUMS IEKŠDEDZES DZINĒJOS @ Kopsavilkums: Piedāvātā ierīce (fig.1) taisnvirziena turpatpakaļkustības pārveidošanai par rotācijas kustību, sastāvoša no piedziņas diska, kas uzstādīts iekšdedzes dzinējā klaņa vietā, ļauj palielināt virzuļa gājienu un samazināt agregāta kopējo svaru. Piedāvātas arī divas ierīces izmantošanas alternatīvas, kuras abas rakstungas ar to, ka iekšdedzes dzinēju konstrukcijā nav klaņu. Pirmajā dzinēja variantā (fig. 1E) divtaktu dzinējamirviena kloķvārpsta (5) un viens turpatpakaļkustības pārveidošanas disks (1), kurš ir izveidots virzuļa (3) un cilindra (4) iekšienē. Otrajā dzinēja konstrukcijas variantā (fig.2) ir izmantotas divas kloķvārpstas un divi turpatpakaļkustības pārveidošanas diski. Kloķvārpstas komplektā ar minētajiem diskiem ir izvietotas dzinēja korpusā vertikālā plaknē savstarpēji paralēli un spoguļsimetrijā. Uz abiem kustības pārveidošanas diskiem ir izvietots viens virzuļu (3) bloks tā, ka slodze uz abām kloķvārpstām sadalās vienmērīgi. Abas piedāvātās alternatīvas var izmantot arī neliela izmēra un paaugstinātas jaudas četrtaktu dzinēju un dīzeļdzinēju izgatavošanai.MOVEMENT AND ITS APPLICATION TO INTERNAL COMBUSTION ENGINES @ Summary: The proposed device (Fig.1) for converting a straight-line reciprocating motion into a rotary motion, consisting of a drive disk mounted in place of an internal combustion engine crank, increases the stroke of the piston and reduces the overall weight of the unit. There are also two alternatives to using the device, both of which are characterized by the absence of cranks in the design of internal combustion engines. In the first version of the engine (Fig. 1E), the two-stroke engine comprises one crankshaft (5) and a single reciprocating conversion disc (1) formed inside the piston (3) and the cylinder (4). In the second version of the engine design (Fig. 2), two crankshafts and two rear-wheel drive discs are used. The crankshafts complete with these discs are located in a vertical plane parallel to each other and in mirror symmetry in the motor housing. A single piston assembly (3) is located on both motion conversion discs so that the load on both crankshafts is distributed evenly. Both of these alternatives can also be used for small and high-powered four-stroke and diesel engines.

Claims

Formula of the Invention

1. A device for converting a straight-line reciprocating motion into rotary motion for use in internal combustion engines, characterized in that a crank shaft is mounted on the crankshaft instead of a crank for the internal combustion engine, in order to secure the crank on the center of the shaft rotating around the crank neck, at one point coinciding with the center of the crankshaft axis, the drive disk is inserted into the housing of the piston which reciprocates the cylinder, rotates the reciprocating motion of the piston body around its axis and transfers it to the crankshaft.

2. The use of a motion conversion device according to claim 1 in a two stroke two-cylinder engine arrangement with oppositely disposed cylinders having a single crankshaft with a drive disk instead of a crank, the device consisting of a housing containing bearings or bushes for crankshaft co-mounting, and the drive disk and the crankshaft are housed in a piston block socket, which in turn is housed within a single cylinder.

3. The use of a motion conversion device according to claim 1 in a two-stroke two-cylinder engine arrangement with oppositely disposed cylinders having two crankshafts with drive discs in place of the cranks, the device consisting of a housing in which bearings or bushes are mirrored symmetrically and mutually parallel to each other. a crankshaft which is in continuous engagement by means of gears on which the drive discs are mounted, the crankshaft drive discs being provided with a single piston block which is common to both shafts and which in turn is housed in one common cylinder.
