Definitions
- the invention relates to piston machines, in particular to machines with a rodless mechanism for converting reciprocating pistons into rotational motion of the working shaft and can be used in engines, for example, internal and external combustion, steam, hydraulic, etc., and various types of pumps .
- the known machine contains a housing with cylinders, the pistons of which are pairwise rigidly interconnected by rods articulated through bearings with the necks of a planetary rotating crankshaft located in the housing, a power removal shaft with its synchronization device movements mounted in the housing.
- the power removal shaft is made of two parts with cranks bearing for securing the extreme necks of the crankshaft in them, and the motion synchronization device is a connecting shaft with gear gearing of the crankshaft crowns.
- the mechanism of this machine can be used not only for internal combustion engines, but also for drive compressors, pumps, reciprocating gas generators and other reciprocating machines.
- the objective of the invention is to improve a piston machine with a rodless mechanism by changing the design of the crankshaft and power take-off shaft to ensure simplification of the assembly and balancing of moving parts while reducing its weight and dimensions and increasing the specific power removed from the power take-off shaft.
- a power removal shaft with a motion synchronization device installed at according to the invention, the crankshaft is made of two articulated double cranks located in eccentrically arranged holes of the bushings having crowns, the power removal shaft with the synchronization device of the movement of the bushings is made of two parts, each of which has gears engaged with each other and crowns of bushes.
- the machine may contain two cylinders, the pistons of which are rigidly interconnected by rods installed between the crankshaft bushings, or four cylinders, whose pistons are rigidly interconnected by rods, mounted on the edges of the crankshaft bushings, or two cylinders, whose pistons are rigidly interconnected themselves rods installed between the bushings, and four cylinders, the pistons of which are rigidly connected to each other by rods mounted on the edges of the crankshaft bushings.
- the eccentricity of the crankshaft and the holes for it in the bushings is 1/4 of the piston stroke.
- the double cranks of the crankshaft and the sleeve have an opposite direction of rotation, while the crank of the crankshaft and its corresponding sleeve also have an opposite direction of rotation.
- FIG. 1 is an isometric schematic view of a piston machine with two cylinders
- FIG. 2 is an isometric schematic view of a piston machine with four cylinders
- FIG. 3 is an isometric schematic front view of a piston machine with six cylinders
- FIG. 4 is an isometric schematic rear view of a piston machine with six cylinders
- FIG. 5 is an isometric view of the crankshaft from double cranks: a - separately, b - in assembled form.
- the inventive piston machine with a rodless mechanism comprises a housing 1, consisting of two symmetrical parts, with cylinders 2, the pistons 3 of which are pairwise rigidly interconnected by rods 4, articulated through bearings 5 with side 6 and central 7 necks of a planetary rotating crankshaft (Fig. 5 ) located in the housing 1 and made of two double cranks 8, 9 pivotally articulated by the central neck 7, located in the eccentrically located holes 10 of the bushings 11 having the crowns 12, the power tap 13 with the synchronization device Of the movement, made of two parts, each of which has gears 14 that engage with each other and the crowns 12 of the bushings 11.
- Assembling a piston machine (using an example of a machine with two cylinders) is carried out as follows: install a sleeve 11 in one of the parts of the housing 1 and a crank 8 in it with a central neck 7 with which the bearing 5 of the piston rod 3 of the cylinders 2 is combined, while the rod slider ( in Fig. not shown) combine with guides (in Fig. not shown).
- One of the parts of the power removal shaft 13 is installed in this part of the housing 1, combining its gear 14 with the crown 12 of the sleeve 11.

- crankshaft of two articulated double cranks allows you to simplify its assembly.
- the placement of double cranks in the eccentrically located holes of the bushings and their opposite rotation in pairs facilitates the balancing of the moving parts of the piston machine.
- the dimensions and weight of moving parts are significantly reduced, as a result of which the power spent on their movement decreases, and the specific power removed from the power removal shaft increases.
- the inventive piston machine operates as follows.
- the pistons 3 move reciprocally in the corresponding cylinder 2. Together with the pistons 3, the piston rods 4 move with sliders in the guides (not shown in FIG.) Fixed in the housing 1, which remove the emerging lateral loads.
- the piston rod 4 being in a hinge connection with the central neck 7 of the crankshaft, drives it into planetary rotation in the bushings 11 and around its own axis.
- the opposite rotation of the bushings 11 is carried out by the gears 14 of the power take-off shaft 13, which engage with each other and the crowns 12 of the bushes 1 1.
- the power of the piston machine is removed from any part of the power take-off shaft 13.
- the piston machine When the piston machine is in engine mode, the energy of the working fluid is converted, fed into the cylinders 2, into mechanical energy.
- the pistons are injected or compressed into the fluids.

Abstract
L'invention concerne une machine à piston comprenant un mécanisme sans bielles, laquelle comprend un corps (1) avec des cylindres (2), des pistons (3) qui sont connectés rigidement entre eux par paires par des tiges (4) couplées via des paliers (5) par les goujons (6, 7) d'un vilebrequin tournant de façon planétaire, lequel se trouve dans un corps (1) et comprend deux manivelles doubles (8, 9) connectées par charnière et disposées dans des ouvertures excentriques (10) de coussinets (11) comportant des couronnes (12), et un arbre de sortie de puissance (13) avec un dispositif de synchronisation de son mouvement qui se compose de deux parties comportant chacune des pignons (14) qui s'engrènent entre eux et les couronnes (12) des coussinets (11). Cette invention permet de faciliter l'assemblage et l'équilibrage des pièces en mouvement tout en réduisant le poids et les dimensions hors-tout de la machine. Il est également possible de diminuer la puissance spécifique que l'on peut obtenir de l'0arbre de sortie de puissance.
