RU51110U1 - AXIAL PISTON ENGINE - Google Patents

Abstract

The invention relates to piston machines with cylinders parallel to the shaft, such as axial piston internal combustion engines, pumps, hydro-pneumatic motors, etc. Effect: transmission of reactive torque to the engine housing through the pistons or through the cross-head mechanisms of the pistons. The axial piston engine comprises a housing 1, a shaft located therein with an oblique crank 2 and a sleeve 3 mounted on it. The piston 5 is connected to the rod 6 by means of piston fingers 7. The washers fixed in the piston 5 exclude lateral movement of the fingers 7. One of the rods 6 is connected to the sleeve fixedly, the rest is articulated, for example, by the axis 9. At the time of the stroke, the gas pressure acts on the piston 5 and through the piston pin 7 transfers force to the piston rod 6, which acts through the sleeve 3 on the oblique crank 2, creating a twisting shaft torque 3.

Description

The invention relates to piston machines with cylinders parallel to the shaft, namely, axial piston internal combustion engines, and can be used as a pump, hydro-pneumatic motor, etc.

The prior art axial piston engines with parallel cylinders and a shaft with an oblique crank.

So, in US patent No. 5027756, IPC F 02 B 45/26, NPK 123/58 R, publication date July 2, 1991, [1], an axial piston internal combustion engine is presented, comprising a housing located therein with a crankshaft an oblique crank and a sleeve mounted on it, cylinders with pistons located parallel to the axis of the shaft connected to the housing by means of bearing bearings. Each rod is connected to the piston pin with the possibility of angular movement relative to the axis perpendicular to the axis of the piston. Piston rods are rigidly connected to an inclined washer mounted on an oblique crank, as a result of which, when the oblique crankshaft rotates, the piston rods move along a trajectory close to the figure eight. This makes it difficult to transmit reactive torque to the engine casing, which is a disadvantage of the engine presented and adopted as the closest analogue of the invention.

The technical problem to be solved is the transmission of reactive torque to the engine housing through the pistons or through the cross-head mechanisms of the pistons.

The essence of the utility model is as follows.

The technical result is achieved by the fact that in an axial piston internal combustion engine containing a housing, a crankshaft with an oblique crank and mounted on the latter sleeve and cylinders with pistons, the axes of which are parallel to the axis of the crankshaft, and the sleeve is connected to rods kinematically connected with the pistons , according to the invention, the connection of the sleeve with the rods is movable with the possibility of angular movement of the rod around the axis of the sleeve or an axis parallel to the axis of the sleeve, and one or two opposing rods can be oedineny with the sleeve still.

In addition, the rods are connected to the pistons by means of cross-head mechanisms, each of which consists of a rod connecting the pistons and passing through bushings connected to the housing, thereby relieving the pistons from lateral forces.

The utility model is illustrated by drawings.

Figure 1 presents the kinematic diagram of an axial piston engine.

Figure 2 presents the kinematic diagram of an axial piston engine equipped with a crosshead mechanism.

Figure 3 shows a section aa in figure 1.

Figure 4 shows a side view of the sleeve.

Figure 5 shows a section bB in figure 4.

Axial piston engine is arranged as follows. The axial piston engine contains a housing 1, a shaft (crankshaft) located in it with an oblique crank 2 and a sleeve 3 worn on it. Pistons 5 are kinematically connected to the rods 6 using piston pins 7. Washers 8 mounted in the piston 5 prevent lateral movement fingers 7. When the engine is eight-cylinder, seven rods 6 are connected to the sleeve 3 pivotally, for example, by means of axes 9 parallel to the axis of the sleeve 3, or by any other device that allows the rods 6 to rotate around the axis of the sleeve or axes, pairs allelic axis of the sleeve, and one rod 6 is connected to the sleeve 3 rigidly. Two opposing rods 6 can be rigidly connected to the sleeve 3. All rods 6 can also be connected movably to the sleeve 3.

To unload the pistons 5 from lateral forces, a crossscopic mechanism can be used in which a pair of pistons 5 are connected by a rod 10 passing through bushings 11 fixed in the housing 1.

Axial piston engine operates as follows. At the time of the stroke, the gas pressure acts on the piston 5 and the piston pin 7, transmitting force to the rod 6, which acts through the sleeve 3 on the oblique crank 2, creating torque on the shaft.

The degree of disclosure of the engine device presented in the description of the invention is sufficient for the development and manufacture of the engine in any specialized enterprise. The manufactured current engine model confirmed the operability of the presented kinematic scheme.
