Description

Device for conversion of a swinging motion into a rotational motion
The subject of the invention is a device for conversion of a swinging motion into a rotational motion.
Presently known devices for conversion of a swinging motion into a rotational motion have a complicated design, comprise many parts and their operation has so many faults that it is unprofitable to make use of a swinging motion to get a rotational motion, for example in combustion engines.
Development of such transmissions tends towards a creation of a device which would have the least weight and the lowest complexity, having the best efficiency and getting a uniform motion.
The essence of the invention is that in the device for conversion of a swinging motion into a rotational motion, the swinging motion which is transmitted by a cross fixation, a cross, a skew crank which converts the motion into the rotational motion of a crankshaft and the skew crank by its motion draws a cone which top/vertex is an intersection point of symmetry axis of the crankshaft, the rotation axis of the swinging motion and the symmetry axis of the skew crank.
The principle of operation of the device for conversion of a swinging motion into a rotational motion is that the angle of the swinging motion is equal to the angle of the motion cone vertex drawn by the skew crank in its projection onto a plane which is perpendicular to the rotation axis of the engine shaft.
The device for conversion of a swinging motion into a rotational motion comprises a shaft making swinging motion, a cross fixation, a cross, a skew crank and a crankshaft.
The shaft making the swinging motion is connected by the cross fixation to the cross which is connected to the skew crank, as a result of which, as a consequence of the swinging motion of the cross fixation at a defined angle value, the cross deflects itself to the angle and transmits the turning moment to the skew crank, forcing in such way the rotational motion of the skew crank and the output crankshaft.
In the device for conversion of a swinging motion into a rotational motion the symmetry axes of the crankshaft and of the shaft performing the swinging motion are situated at an angle of 10° to 170°. It is advantageous when the angle value is 90° and the rotational motion made by the arm of the skew crank connected to the cross by the symmetry axis draws the cone of which the vertex angle in its projection onto the plane perpendicular to the rotary axis of the shaft performing the swinging motion is equal to the angle value of the swinging motion.
In case of when the angle value between the symmetry axes of the crankshaft and the engine shaft is 90° the rotational motion made by the arm of the skew crank connected to the cross by the symmetry axis draws the cone which the vertex angle value is equal to the angle value of the swinging motion.
The subject of the invention is shown in the attached figures where fig.l shows the device for conversion of a swinging motion into a rotational motion in an axonometric view with visible hidden edges and with the swinging motion angle and the skew crank angle in relation to the crankshaft, fig.2 shows the device for conversion of a swinging motion into a rotational motion without the hidden edges, with marked symmetry axes of the shaft performing the swinging motion, the skew crank and the crankshaft, fig.3 shows the device for conversion of a swinging motion into a rotational motion in a top view with marked symmetry axes, fig.4 shows the device for conversion of a swinging motion into a rotational motion as a side view, fig.5 shows a diagram of the cone creation/drawing of which the vertex angle value is equal to the swinging motion angle value with marked symmetry axes of the shaft performing the swinging motion, the skew crank and the crankshaft.
In the device for conversion of a swinging motion into a rotational motion the shaft performing the swinging motion 1 performs the swinging motion and by the cross fixation 2, and the cross 3, and the skew crank 4 it converts a swinging motion into a rotational motion of the crankshaft 5, and the skew crank 4 by its movement draws the cone which has the top/vertex in an intersection point of crankshaft symmetry axes of the crankshaft 8, the axis of the shaft performing the swinging motion 6 and the skew crank 7.
The principle of operation of the device for conversion a swinging motion into a rotational motion is that the swinging motion angle 2α is equal to the angle 2α of the motion cone vertex drawn by a rotation of the skew crank 2 in its projection onto the plane perpendicular to the rotation axis of the shaft performing the swinging motion 6.
The swinging motion made by the shaft 1 is transmitted by the cross fixation 2 to the cross 3 which is connected to the skew crank 4 as a result of which and as a consequence of the swinging motion of the cross fixation 2 at a defined angle value 2a, the cross 3 deflects itself to the angle 2α and transmits the turning moment to the skew crank 4 and to the output crankshaft 5.
In the device for conversion of a swinging motion into a rotational motion the symmetry axes of crankshaft 8 and of the shaft 1 making the swinging motion create the angle with the value from 10° to 170° and it is advantageous when the angle value is 90° and the rotational motion made by the arm of the skew crank 4 connected to the cross 3 by the symmetry axis 7 draws the cone of which the vertex angle 2α in its projection onto the plane perpendicular to the rotary axis of the shaft 1 performing the swinging motion is equal to the angle value 2α of the swinging motion. In case of when the angle value between the symmetry axes of the crankshaft 8 and the engine shaft 6 performing the swinging motion is equal to 90° so the rotational motion made by the arm of the skew crank 4 connected to the cross 3 by the symmetry axis 7 draws the cone of which the vertex angle value is equal to the angle value 2α of the swinging motion of the shaft 1.
