MECHANISM OF MUTUAL TRANSFORMATION OF ROTARY MOTION TO RETURN-SENDING.

The proposed utility model relates to mechanical engineering and can be used, in particular, in reciprocating internal CI cranking engines to convert the energy of reciprocating motion of pistons into rotational energy without a crankshaft.

Known cam mechanism for converting rotational motion into rocking, containing a housing with gfivodnym shaft, on which an inclined washer (disk) is rigidly fixed, interacting with two rollers and a rocker mounted on a horizontal axis of rolling (AS No. 1762055, F16H23 / 00, 1992).

The disadvantages of this mechanism should be attributed to its limited operational capabilities, since it is impossible to convert the reverse process - the rocking motion into rotational one, since the vector of the force acting through the beam on the rollers and the straight line connecting their axes and the axis of rotation of the washer (disk) lie in one plane, which creates the effect of “dead center”. In addition, the mechanism has a small energy intensity and is not suitable for transferring large forces to its moving parts,

The technical problem posed before the utility model is to expand its operational capabilities, increase energy and dynamic characteristics.

This technical problem is solved by the fact that in the mechanism of mutual conversion of rotational motion into reciprocating, containing a housing with a drive shaft, on which an inclined disk is rigidly fixed, interacting with two rollers and a rocker mounted on a horizontal axis of rolling, the rocker is made in the form of a ring , the plane of which is parallel to the plane of the disk, and the inner diameter is larger than the diameter of the disk, the rollers are mounted in diametrically opposed chutes of the ring in a vertical plane and without interact with one side of the disk, while the straight lines passing through the axis of rotation of the rollers and the axis of swing of the ring are mutually perpendicular in space and intersect with the axis of rotation of the shaft at points whose distance between them is equal to the largest radius of the rollers, which can be either conical or barrel-shaped, or spherical, and the disk along the periphery is equipped with a kayak, the profile of which corresponds to the outer profile of the rollers

This design of the mechanism will improve its dynamic and energy characteristics and use it in reciprocating internal combustion engines without a crankshaft.

Figure 1 shows the mechanism, side view. Figure 2 is a front view.

The proposed mechanism comprises a housing 1, in which a drive shaft 3 with a flywheel is mounted by means of bearings 2, an inclined disk 5 is fixed rigidly on the shafts 3, the axis of rotation of which makes a certain angle C with the axis of rotation of the shaft. Parallel to the plane of the disk 5 on the horizontal axis of rolling 0-0 by means of pins 6 a ring 7 is installed, the inner diameter of which is larger than the diameter of the disk 5, and the axis of rolling of the ring is “0-0 perpendicular to the lot of the axis of the shaft 3 and intersects with it. Inside the rim of the ring 7, rollers 9 are mounted on the axes 8 at diametrically opposite points in the vertical plane; the rollers 9 can interact with one side of the disk 5 without a gap, either end-shaped, barrel-shaped, or spherical, and on the periphery the disk 5 is provided with a groove whose profile Corresponds to the outer profile of the roller. In this case, the straight line “B-B, passing through the axis of rotation of the rollers and the axis“ 0-0 of the ring rolling mutually ne}) are pendicular in space and intersect with the axis of the shaft at points whose distance h is equal to the maximum radius of the rollers. On the rim of the ring 7 at the trunnion pins 6 mounted rods 10 pivotally connected to the pistons of the vertical reciprocating movement (not shown). And at the points of installation of the rollers 9, rods attached to the pistons of the horizontal reciprocating movement (not shown) are attached to the ring rim.

Thus, the proposed mechanism provides reciprocating movement of two pairs of pistons in the vertical and horizontal planes. The same design, located on the back of the flywheel 4, makes it possible to double the number of pistons and engine cylinders to eight without a crankshaft, compact design and reliable dynamics.

In relation to a reciprocating internal combustion engine, the mechanism operates as follows.

When the engine is started, the flywheel 4 rotates and, through the shaft 3, rotates the lower disk 5, which, in turn, interacting with the rollers 9, swings the ring 7. The oscillating movement of the ring 7 through the connecting rods 10 is converted into the reciprocating movement of the vertically arranged pistons (i.e. shown ), and through the rods mounted on the rim of the ring at the locations of the rollers 9, the reciprocating movement of horizontally located pistons is provided (rods and pistons not shown). When the engine is running,

the reverse process of converting the energy of reciprocating transposition of pistons into the energy of the rotational motion of the drive shaft through P1 rod, rods, ring, rollers and inclined disk.

In this case, the vectors of forces acting on the disk are located at an angle to its plane, as a result of which the forces are decomposed into two components - axial and radial. The axial force is absorbed by the shaft bearings, and the radial force forms a torque, which leads to the rotation of the drive shaft.

The use of this mechanism in the internal combustion engine in the absence of a crankshaft reduces the pressure of the pistons on the cylinder walls, which reduces their wear and increases the life of the engine.
