Description

1 80324 METHOD OF CRANKSHAFT TMS. ROTARY BODY MOVEMENT AND PISTON-ARM TMS. TO FOCUS THE MOVEMENT OF A RETURNING MOVEMENT.

The object of the invention is to align the parts of the movements of the eccentrically rotating body of the crankshaft or the like and the reciprocating parts of the piston rod or the like connected thereto.

A method of connecting an eccentrically rotating body of a crankshaft or the like to a reciprocating body (e.g., a piston rod) using two rotating rods is known from United States Patent 3,941,003 Mar 2, 1976.

In this publication, the reciprocating rod using the mower blade (Fig. 2, part 48) is connected by bearings with two rotating rods (Fig. 2, part 68) to a bearing (Fig. 3, part 70) on a bearing-mounted body (Fig. 2, part 60).

The aim of the coupling method is to cause the reciprocating parts of the mower to move as much as possible in the shape of a sine curve, so that the deceleration of the movement at almost extreme positions would take place at the same speed at both ends. In this case, it has become possible to eliminate the harmful vibration caused by the deceleration of the movement by means of rotating counterweights (parts 40 and 44 of Fig. 3). The substantially sinusoidal movement is achieved by the device by placing the rotary levers (Fig. 2 part 68) in their basic position parallel to the reciprocating movement of the reciprocating rod (Fig. 2 part 48). In their basic position, the rotating rods (parts 68 of Fig. 2) are in both extreme positions of movement of the reciprocating rod (part 48 of Fig. 2). The mechanism described by TE is applied in Figure 3.

There is no prior knowledge of the alignment of the parts of the rotation of the crankshaft or the like of the eccentrically rotating body and the parts of the movement of the reciprocating body of the piston rod or the like. It is customary to keep this ratio constant, which is determined by the length of the crankshaft palm and piston rod.

However, using the method according to the invention, the encounter of the movements of the crankshaft or the corresponding eccentrically rotating body and the piston rods or their corresponding reciprocating bodies 280324 can be structurally determined. This planned selection of meeting points is referred to in this patent application as targeting.

As a result of the targeting, for example in internal combustion engines, there is an opportunity to improve the fuel efficiency, when the most efficient part of the combustion on the piston can be directed to a more advantageous area of the crankshaft revolution.

In compressors or similar devices in which the stress caused by the cylinder used is applied to the drive machine as a strong working peak, the stress peak can be reduced by applying it to a wider area by a part of the crankshaft rotation of the machine used. In this case, the power requirement of the operating machine is lower.

In order to achieve the above effect, the invention is mainly characterized by the features set forth in claim 1.

The figures show the mechanism connecting the crankshaft and the piston rods. Figure 1 is a cross-section at the piston rods. The dashed lines therein show different angles of intersection of the support arms (3) with respect to the line of the piston rods. The dashed line 0 is parallel to the trajectory of the piston rods.

List of components: 1 Body 2 Support ring 3 Support arm 4 Support arm shaft 5 Palm orbit 6 Palm rotation direction 7 Piston rod guide 8 Piston rod 9 Movable support arm shaft point 10 Crank 11 Crankshaft housing 12 Crankshaft bearing 13 Crankshaft bearing

Structure of the device: A crankshaft (13) is attached to the body part (1) by frame bearings (14), on the neck of which a elongated comb bearing housing (11) is placed on the neck of the palm (10) to protect the bearing (12) and transmit forces. The crankshaft housing is fixed at each end by means of shafts (4) to the support arms (3), the other ends of which are fixed to the sides of the support ring (2) by means of movable support arm shafts (9). Attached to the sides of the support ring are 4 80324 piston rods (8) which pierce the body part (1). A piston rod guide (7) is placed at the piercing point.

Operation of the device: As a result of combustion on the piston, the piston begins to push the support ring (2) towards the crankshaft (13) via the piston rod (8). The movement is further transmitted by support arms (3) which, by means of their shafts (9 and 4), fasten the support ring and the crankshaft bearing housing (11) to each other. Through the crankshaft housing, the crankshaft bearing (12) and the palm (10), the movement is transferred to the rotational movement of the crankshaft (13). The function of the support arms and the crankshaft housing is also to quench the lateral movement caused by the palm, while allowing the movement in the direction of the piston rods and controlled by the piston rod guides (7) to take place.

In compressor operation or similar operation, where the device is built as part of the mechanics used, the movement also takes place in the reverse order.
