Description

TENSIONED INERTIAL DISC, CYLINDRICAL HOUSING INERTIAL FLYWHEEL, AND KINETIC MECHANICAL SYSTEM FOR PERFORMING WORK TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of Mechanics, Physics and Kinetics, since it refers to a tensioned inertial disc that releases centrifugal force; to a cylindrical housing inertial flywheel that provides centrifugal force from the tensioned inertial disc; and a kinetic mechanical system to perform work by taking advantage of the centrifugal force provided by the cylindrical housing inertial flywheel. BACKGROUND OF THE INVENTION Currently, the kinetic mechanical systems that take advantage of the centrifugal force released from flywheels, as disclosed in patent documents WO2017217834 (A1), MX2018002258 (A) and MX / a / 2020 / 001677 (A), have a first drawback observed in the sliding inertial masses: these do not contribute centrifugal force at the beginning of the system's rotation, which throws off the synchronization of the rotation of the rotary actuator with the rotation of the crankshaft driven by the connecting rods and cams. This is because the cams do not receive force from the sliding inertial mass at the beginning of the system's rotation;The second drawback is observed in the kinetic mechanical system. It lies in the rigid, four-gear secondary power transmission located at the rear of the system. This transmission is ineffective at transmitting the centrifugal force received by the cams directly to the crankshaft, as part of the centrifugal force is absorbed directly by this rigid transmission. Such systems require high precision in the force released upon contact with the cams, especially during system startup, where the force must reach the crankshaft directly. The third drawback is found in the discs attached to the counterweight inertial mass. These discs also serve to suspend... -2The sliding industrial mass, the drawback is that these discs receive the useful centrifugal force and this is not transmitted to the cam, connecting rod and crankshaft, the discs are what -to a large extent- nullify the centrifugal force, they nullify it by means of the semicircular prominence of the sliding industrial mass itself, said prominence makes contact with the discs because it is inside the semicircular perforation of the rigid circular discs themselves; the fourth drawback is not taking into account the angle of incidence, this is formed between the radial direction that is formed from the axis of rotation of the flywheel, to the center of mass of the sliding industrial mass itself, with the other radial direction that is formed from the axis of rotation of the wheel of the sliding mass, to the point where said wheel makes contact with the curved cam.The angular difference between these two radial directions forms an angle and is called the angle of incidence; at the precise moment of contact of the wheel with the cam, this angle is an impact factor, the greater the angle, the greater the impact and this can be minimized by decreasing the angle of incidence at the precise moment of contact, so it is important to minimize the angle of incidence and the impact. In order to contribute to the solution of the aforementioned problems, a tensioned mercury disc that releases centrifugal force was developed; a cylindrical housing mercury flywheel that provides the centrifugal force from the tensioned mercury disc; and a kinetic mechanical system to perform work by taking advantage of the centrifugal force provided by the cylindrical housing mercury flywheel.

Tensioned industrial disc (A) with the ability to release centrifugal force. In the first instance, the present invention relates to a tensioned inertial disk (A) capable of releasing centrifugal force, which is configured with a sliding inertial mass (1) and a counterweight inertial mass (2), each configured as a solid body in the shape of a half-disc, close to each other, but not in contact, by means of their diametral sides (5) in a horizontal plane; where said inertial masses (1) and (2) are joined by a pair of rigid circular plates (18) that hold the counterweight inertial mass (2) and suspend the sliding inertial mass (1) to allow its displacement and thereby acquire the capacity to release centrifugal force. These inertial masses (1) and (2) are extensively described in patent document MX / a / 2020 / 001677. The modification or improvement to said tensioned mercury disc (A), of the present invention, lies in the inclusion of a central spring (42') housed in a compressed manner, within the tubular cavity formed by the duct (14) of the sliding mercury mass (1) and the wall of the fork (16) of the counterweight mercury mass (2), see figures 3, 4 and 6. It should be noted that the diameter of said duct (14) was modified to the size necessary to house the central spring (42') and its length was also less than the length of said spring (42') in its expanded condition. In one embodiment, said tensioned inertial disk (A) may further comprise at least one lateral spring (42) in each section between the semicircular concave depression (5') of the sliding inertial mass (1) and the semicircular fork (16) of the counterweight inertial mass (2), and the perimeter ends of the diametral sides (5) of both inertial masses (1) and (2), as illustrated in Figures 3, 4, and 5. The lateral springs (42) interconnect both inertial masses (1) and (2), but without any contact between them; for this purpose, each mass o? / znn / zznz / e / YiAi The inertial masses (1) and (2) have at least one straight hole (14a) and (14b), respectively, in each of them. The straight holes (14a) and (14b) originate from the diametral sides (5) of the inertial pieces (1) and (2), and are projected perpendicularly, with respect to said diametral side (5), into their solid bodies; where the straight hole (14a) is located intermediate in each section between the semicircular concave depression (5') and the perimeter end of said perimeter side (5) of the sliding inertial mass (1), as can be seen in figure 1; and the straight hole (14b) is located intermediate in each section between the semicircular fork (16) and the perimeter end of said perimeter side (5), but of the counterweight inertial mass (2), see figure 2. It is important to mention that the entrances of the straight holes (14a) and (14b) must perfectly match in dimensions, shape and location, so that when the diametral sides (5) of the inertial masses (1) and (2) are brought face to face, they are close (without making contact between them) in opposite directions by their entrances, thus forming a tubular cavity where a lateral spring (42) is housed in a contracted condition; therefore, the length of said tubular cavities must be less than the length of the lateral springs (42) in their expanded state, see figure 4. The function of the springs (42) and (42') in their compressed condition is to keep the sliding inertial mass (1) separate from the counterweight mass (2), with a permanent tension force, since the circular pieces (18) are responsible for keeping the inertial masses (1) and (2) together in the correct position to rotate like a disk; and the compressed springs (42) and (42') ensure that the inertial masses do not have any contact on their diametrical sides (5) to avoid mass imbalance when they are in their rotary motion. o? / znn / zznz / e / YiAi A further modification to said tensioned inertial disk (A) was that the edges of the central perforation (15) and the edges of the semicircular fork (16), of the inertial mass (2), were extended into a circular projection (13) to achieve ease and -7precision when assembling the two inertial masses (1) and (2), when they are tensioned, this allows the rigid circular plates (18) to be placed easily and accurately. It should be noted that the semicircular protrusions (13) were removed from the sliding inertial mass (1). Therefore, this reference (13) was assigned to the new circular protrusion (13) mentioned earlier, which was located concentrically near the semicircular depression (5'). Consequently, the rigid circular plates (18) were modified to fit the flat circular faces (3) formed by the appropriate placement of the inertial masses (1) and (2) in the same plane. One modification involved increasing the diameter of the central perforation (20) in the circular plates (18) to allow for a snug fit through the circular protrusion (13) of the counterweight inertial mass (2). Another change was the elimination of the semicircular perforation (19) because the semicircular protrusion (13) had been removed. II. Industrial flywheel with cylindrical housing, capable of providing centrifugal force. A second object of the present invention is a cylindrical-cased flywheel capable of generating centrifugal force. This flywheel comprises at least one tensioned disc (A) capable of releasing centrifugal force, incorporating the modifications proposed by the present invention. It also includes a rotating tubular shaft (25) that supports and rotates the tensioned disc (A), as shown in Figures 9 and 10. This tubular shaft (25) further comprises at least one set of fastening elements at the point where the tensioned disc (A) is attached. These fastening elements are designed to securely fasten the tensioned disc (A) to the rotating tubular shaft (25). Further details of the rotating tubular shaft (25) and all other components of this flywheel can be found in patent document MX / a / 2020 / 001677. qj / znn / zznz / B / YiAi -8The cylindrical housing flywheel of the present invention also comprises a cylindrical housing (B) where at least one tensioned inertial disc (A) is housed, inserted into the tubular and rotating shaft (25).One embodiment of the cylindrical housing (B) is as illustrated in Figures 12, 13, 14, 15, and 16, where it is formed from a cylindrical body (50), which can be configured as two halves or as a single piece; said cylindrical body (50) has at least one arc groove (51) whose length must be within an angle > 91° taking as a reference the center of the tensioned inertial disk (A), see Figure 16 where in this example it has an angle of 110°; and at least one pair of internal circular supports (53) having a central perforation (54), which are fixed separately from each other, internally and perpendicularly to the inner wall of the cylindrical body (50), the arc groove (51) being between said internal circular supports (53), to suspend the rotating tubular shaft (25) which in turn supports the tensioned inertial disk (A).Therefore, two separator cylinders (59) are required to separate each of the tensioned inertial discs (A), and these separator cylinders (59) surround the rotating tubular shaft (25) and are located on each side of the tensioned inertial disc (A), making contact with the circular projection (13); and two annular bearings (58) are also required for each tensioned inertial disc (A), which surround the rotating tubular shaft (25), and each one is located at the free end of each cylindrical separator (59) and within the central perforation (54) of the internal circular supports (53).In this way, a tensioned inertial disk (A) is located between two internal circular supports (53), but with free rotary movement on the rotating tubular axis (25) where the circular rolling element (6) of the tensioned inertial disk (A) always makes contact with the inner wall of the cylindrical body (50) which serves as a bearing track for the rolling element (6), which, when passing through the path of the arc groove (51), will push out of the cylindrical body (50), the pivoted element (32), which is suspended and has a portion inside the cylindrical body (50) through the transverse perimeter groove (51). o? / znn / zznz / e / YiAi -9It should be noted that this embodiment of the housing, in two concave halves, is because it facilitates the assembly of said steering wheel, and therefore there are other embodiments of said housing, which are included within the scope of protection of the present invention. For example, it is preferred that the cylinder (50) and its internal circular supports (53) be a single piece without being divided into two halves. In one embodiment of the cylindrical housing flywheel, it may comprise at least one external support (52) configured to support and reinforce the cylindrical housing (B), see figures 12, 13, 14, 15 and 16. Optionally, when the cylindrical housing (B) is made up of two halves, at least one connecting bar (52') is required to reinforce the joint between the two halves of the cylindrical housing (B), and this connecting bar (52') shall be firmly fixed to the external supports (52) of the two halves of the cylindrical housing (B). A motor (55) is provided to provide rotational motion to the rotating tubular shaft (25), which in turn rotates the tensioned inertial disk (A). In a preferred embodiment of the cylindrical housing flywheel of the present invention, the number of tensioned discs (A) is 4, and therefore the housing has 4 arc grooves (51) distributed parallel to each other, three internal circular supports (53), four external supports (52) and four connecting bars (52'). III. Kinetic mechanical system to perform work, by taking advantage of the centrifugal force provided by the cylindrical housing flywheel. o? / znn / zznz / e / YiAi A third object of the present invention is a kinetic mechanical system for performing work by harnessing the centrifugal force provided by the previously described cylindrical-cased flywheel; therefore, said mechanical system comprises: i) a cylindrical-cased inertial flywheel capable of providing centrifugal force, in accordance with that proposed by the present invention; (i) at least one pivoted element (32) configured to interact operationally with the cylindrical housing flywheel, to transform the continuous circular motion of said flywheel into linear motion by means of the thrust it receives from the circular rolling element (6) of the sliding inertial mass (1) of the tensioned inertial disk (A) when it is in rotational motion, since a part of the pivoted element (32) is suspended within the cylindrical housing (B) through the arc groove (51); and therefore has a clamping element (40) that keeps it suspended and allows it to have pendulum motion; a pivoted cam is an example of a pivoted element; iii) at least one linear motion receiving element (33), such as a connecting rod, operationally connected to the pivoted element (32), to transmit the linear motion to; iv) an element that can perform mechanical work (34) with linear motion; where said element (34) is connected to the receiving element (33) in an operational and functional manner; an example of this element is a crankshaft; (v) a general, robust and rigid casing (37) configured to support and contain within it all the components of the kinetic mechanical system, but which in turn allows the kinetic mechanical system to perform work by interacting with other systems for its use; and (vi) an apparatus (56) operatively attached to the element that can perform mechanical work (34), to take advantage of said work. Figures 18 and 19 show the operation of the kinetic mechanical system, where the cylindrical housing flywheel begins to contribute centrifugal force when the rolling element (6) is positioned linearly between the rotating axis (25) and the axis (40) of the pivoted element (32) (dotted line in Figure 18), since the arc groove (51) usually begins at that point and because the element o? / znn / zznz / e / YiAi The pivoted element (32) always has a portion inside the circular housing (B) through the arc groove (51), so it is there that the rolling element (6) begins to push out the pivoted element (32), ejecting it completely as the rolling element (6) passes through the entire arc groove (51), the rotation is in the direction of the dotted arrows, and as this arc groove (51) has a length contained in an angle > 91° taking as a reference the center of the tensioned inertial disk, it can be said that the rolling element (6) must make a 91° journey to completely eject the pivoted element (32), which when pushed, in turn pushes the receiving element (33) and this in turn actuates the element that can perform mechanical work (34). In one embodiment of the kinetic mechanical system of the present invention, it may comprise supports (57) configured to support the crankshaft. In another embodiment of the kinetic mechanical system according to the present invention, the general housing (37) is made up of: i) two bases (37a), one front and one rear, placed parallel to each other, to support orthogonally in front of them, parallel and equidistant from each other, the rotating tubular shaft (25) of the cylindrical housing flywheel, the shaft of the element that performs mechanical work (34) and at the top of the bases (37a) the clamping element (40) that suspends the pivoted element (32); i) detachable front and rear sections (37b) over the upper edges of the base (37a); and iii) a cover (37c) that fits over the edges of the base (37a) and the front and rear sections (37b). In another embodiment of the kinetic system in question, it also comprises at least two shoes (38) that are fixed collinearly on the o? / znn / zznz / e / YiAi -12 supports (57) in order to give rigidity to the housing (37) and the entire kinetic mechanical system, for good mechanical performance. In a further form of the kinetic system of the present invention, the apparatus (56) that takes advantage of the work is an electric power generator, or any other apparatus that takes advantage of the centrifugal force released by the inertial flywheel of cylindrical casing.
