Abstract
The invention relates to a cam machine with a control mechanism which will find application in various fields of mechanical engineering, such as compressor machines, hydraulic pumps, internal combustion engines and other types of engines in various land, sea and air vehicles, or in stationary units. The created cam machine improves the contact between the cam profiles (15a, 15b) of the cam bushings (16a, 16b) and the followers (1a, 1b). The main improvement of the machine is in the design of the regulating mechanism, which increases the reliability and the service life of the cam machine. In addition, simple and reliable control mechanisms are integrated in the machine, which at the same time simplifies the process of adjusting the cam machines.
Claims13
Cam machine comprising a housing (22, 31 and 21), at least one cylinder (26), at least one piston (25) moving in the cylinder (26), a cylindrical tubular 3D cam (20) with a cam channel on the inner cylindrical surface which channel is made so that the line forming its cross section is the concave line having two cam profiles (15a, 15b) and a bottom (59) between them, which is laterally located relative to the axis of the 3D cam (20) and at least two asynchronously moving followers (1a, 1b) located opposite each other, each follower (1a, 1b) containing at least two arms (37) connected respectively to one of the two pistons (25) or to one piston (25) and a balancing element (60), wherein the arms (37) spaced at an angle to each other are provided with tubular main bearing journals (2) with main rollers (3) placed in bearings at the free ends of the respective arms (37) and each follower (1a, 1b) further comprises cylindrical plungers (6) located in the main bearings journals (2), which cylindrical plungers (6) comprise additional bearing journals (4) bearing additional rollers (5), performing both rectilinear and rotational movement in the direction and around the axes of the respective main rollers (3) so that each main and an additional roller (3 and 5) is in contact with its respective profile (15a or 15b) of the cam channel, characterized in that the tubular main bearing journals (2) have threaded holes (13) in which screw regulators (7) are mounted, contacting indirectly or directly with the plungers (6), where the indirect contact between the plungers (6) and the adjacent screw regulators (7) is made through elastic and bearing elements (8) and (10), and the direct contact is realized by pins (11), each of which is part of the corresponding screw regulator (7), where the maximum clearances (57) formed by the indirect contacts between the pins (11) and the plungers (6) are at least equal to the strokes of the rectilinear motions of the plungers (6) at a complete rotation of the 3D cam (20), and the connections between each plunger (6) and the elements located in its respective bearing journals (2) are such that the plungers (6) are freely removable from the adjacent bearing journals (2) when the cam machine is disassembled.
Cam machine according to claim 10, Characterized in that a gear ring (45) is made on the periphery of the flanges (36a) and (36b) for transmitting mechanical energy to an external working machine or for receiving energy from an external source of mechanical energy.
Two-cylinder compressor or hydraulic pump comprising a cam machine according to the preceding claims, characterized in that they comprise at least one cylinder head (61), hermetically closing the cylinder (26) or one of the cylinders (26), performing a working cycle in it, wherein the fluid exchange accompanying the filling and emptying processes of the cylinder (26) or the cylinders (26) is effected by means (71) and (72) for opening and closing the compressor chamber (73).
