Piston cam drive

A method for determining the specifications of the slope of the tightly fitting faces machined from the interior of the piston will be derived by a geometric construction of vectors of force to derive the milling of the novel slope for the faces abutting an eccentric cam;

• which the premise of this application is, that the eccentricity of the cam determines the slope of the interior machined plane for surfaces in tight contact with the cam at both sides of the cam in a parallel fashion, which is different than a plane drawn thru the center of the cam that is perpendicular to the inner sides of the piston for the purpose of balancing the force exerted by ignition to the piston's heads which will be transmitted to a cam centrally located within the cam by the tightly fitting parallel faces that have been milled within the pistons interior which will transmit this force to the cam at the points of contact at both sides of the cam causing the cam to rotate, so that the torque produced at the cam may be transmitted in a continuous circular fashion by means of its rigidly attached axel to an external device in a fashion permitting it to run at a constant velocity, both as a stand-alone engine or to another gear for the purpose of constructing multi-cylinder engines of such configurations as radial or parallel for a balanced application of force applied to:
• a determination of the degree of eccentricity determines the slope of the abutting faces to the cam within the piston, which is the single embodiment of this application, a method employing a sequence for constructing a geometric figure using cartesian coordinates for the specifications for the milling of this interior space would be as follows:
• an origin point that is the point formed by the intersection of the x and y axis which will be the point and would have a value 0:0, this axis point represents the point center of the eccentric circular cam;
• a point is selected along the y axis which will be the point around which the eccentric cam circle will be scribed;
• a point will be selected between the origin point and the selected point on the y axis used to determine the radius of the eccentric cam circle which will also represent the cam's axel and will have a value greater than zero, and at least greater than the diameter of said axle, and lessor than by that same diameter which is the vector of centripetal acceleration as it applies to the cam's axel;
• a point will be selected between the origin point and the selected point on they axis used to determine the radius of the eccentric cam circle which will also represents the cam's axel and will have a value greater than zero, and at least greater than the diameter of said axle, and lessor than by that same diameter which is the vector of centripetal acceleration as it applies to the cam's axel;
• a measure of the distance between the origin point and the selected point on they axis represents the radius of the eccentric cam circle;
• a line segment will be scribed between the origin point which represents the cam's axel and the selected point on the y axis used to determine the radius of the eccentric cam circle which is the vector of centripetal acceleration as it applies to the cam's axel;
• a perpendicular line to the line segment derived for the radius of the cam circle divided by the measure of centripetal acceleration and that the half on the right side of the y axis is scribed thru the point representing the center of the cam's axle and the intersection of this line with the eccentric cam's circle forms the line segment, the point center of the cam's axle is the bisection of this line segment and forms two equal segments, one would have a positive value the other a negative value, either represents the vector for tangential force as applied to the cam's axle, we will assume that that the half is negative and on the left side of the y axis and that the cam would rotates in a counter clockwise fashion, and that if positive and on the right side the cam would rotate in a clockwise fashion;
• a line segment would be scribed between the point of intersection with the eccentric cam circle on the left by side of the y axis and the eccentric cam circle and the point selected along the y axis used to determine the eccentric cam circle the measure of which is the cumulative vector for force at the cams axle which is the same as the force exerted at the eccentric cam's center;
• a line segment for the cumulative vector for force at the eccentric cam's axle, would then be bisected by a point forming two equal segments the, measure of the segment to the right which would be the tangential force applied to the upper side of the eccentric cam circle while the other portion of the total force is applied to the lower side;
• a line is scribed thru the point of bisection of tangential force to the cam's axle and the point center of the cam then plot the intersection of that line with the cam circle, the line segment drawn between this point and the point of bisection of tangential force to the cam's axle would be the vector for centripetal acceleration at the upper half as applied to the cam's center;
• a segment between the points for the vector for centripetal acceleration at the upper half as applied to the cam's center and the selected point on the y axis used to determine the radius of the cam is scribed which forms the cumulative vector for force at the upper half of the cam which would be the cumulative vector tangential force as applied to the cam's axle;
• the segment for the vector for tangential force as applied to the cam's axle is bisected then scribe a perpendicular line thru this point and plot the intersection of that line with the cam circle which are the point of contact for the parallel faces abutting the cam;
• a line segment for the cumulative vector for force at the eccentric cam's axle, would then be bisected by a point forming two equal segments the measure of the segment to the right which would the tangential force applied to the upper side of the eccentric cam circle while the other portion of the total force is applied to the lower side;
• a tangent to the points of contact for the parallel faces abutting the eccentric cam circle will form the plane along the z axis upon which the opposing faces will be formed;
• a surface milled from the interior of the piston at the points of contact for the parallel faces abutting the eccentric cam circle of contact for the parallel faces abutting the eccentric cam circle form the tightly fitting interior surfaces that upon ignition at either side of the cam will force the cam to rotate in a continuous circular fashion in a symmetric fashion capable of maintaining a constant velocity.
