Abstract

The invention makes it possible to simplify the design of a piston machine with a cordless mechanism for converting reciprocating to rotary motion. The composite working shaft is made of two coaxial parts 1.2c with cranks 3, 4 and a four-knee crankshaft 5 fixed between them. Bearings 6.7 are mounted on cranks 3, 4 and fixed relative to them in the tangential direction. The slides 8-11 are connected to the elbows 12-15 of the shaft 5 through bearings 16-19 and mounted in intersecting fixed guides 20-27. Stationary cylinders 28-31 with pistons 32-35 disposed therein are kinematically associated with sliders 8-11. The bearings are installed with the possibility of rotation around the axis of rotation of the working shaft and reciprocating movement in the direction perpendicular to this axis, and made in the form of axially mounted cylindrical shanks 36 with diametrical slots 8 and 11 mounted on the ends of the working shaft. placed in slots. The ends of the cranks 3, 4 are located in the holes of the sliders 8-11. At least one of the sliders 9 or 10 connected to bends 13, 14 is associated with 32-35. The ends of the shaft 5, through bearings 6, 7, apply a torque to parts 1, 2.2 or less. (L

Description

The invention relates to mechanical engineering, namely to reciprocating volumetric machines, and can be used in internal combustion engines, compressors and other machines.

The purpose of the invention is to simplify the design of a piston machine.

Figure 1 shows a diagram of the proposed machine in a perspective view; figure 2 - the crankshaft support.

A piston machine with a conrodless mechanism for converting a reciprocating movement into a rotational movement contains a composite working shaft made of two coaxial parts 1.2c.

cranks 3, 4 and four-knee crankshaft 5 fixed between them, shaft bearings 6, 7 mounted on cranks 3, 4 and fixed relative to them in the tangential direction, sliders 8-11, connected to elbows 12-15 of shaft 5 through bearings 16 -19 and mounted in crossed stationary guides 20-27, and stationary cylinders 28-31 with pistons 32-35 disposed therein, kinematically connected with sliders 8-11, with bearings 6, 7 mounted with the possibility of rotation around the axis of rotation working shaft and return o

but in a direction perpendicular to this axis, and made in the form of coaxially mounted shafts 36 installed at the ends of the working shaft with diametral grooves 37 on the side of cranks 3, 4 and sliders 8-11 with holes 38 placed in grooves 37, and the ends of the cranks are located in the holes 38, with at least one of the sliders 9 or 10 connected to the middle two elbows 13,14 of the crankshaft 5 connected to the pistons 32-35.

Piston machine works as follows.

During the reciprocating movement of the pistons 32-35 in the cylinders 28-31 together with the pistons, the middle sliders 9, 10 move in their guides 22-25. The slides 9, 10 move the middle elbows 13,14 of the crankshaft 5 along the guides. At the same time, the extreme elbows 12 and 15 of the crankshaft 5 move with the sliders 8, 11 in the guides 20, 21 and 26, 27 and the shaft 5 is rotated around its axis (not shown), which rotates around the axis 39 of parts 1, 2 of the working shaft at a distance equal to the radii of cranks 3. 4. The ends of shaft 5 through the bearings 6.7 apply torque to parts 1, 2 working shaft.
