The Pulsed Power Transmission Method and System thereof A) TECHNICAL FIELD

[001] The present invention generally relates to a field of power transmission and particularly related to the pulsed power transmission method. The present invention more particularly relates to the pulsed power transmission method and system transmitting power in the form of power pulses in order to harness gravitational energy during power transmission.

B) BACKGROUND OF INVENTION

[002] A four-stroke internal combustion engine (i.e. I. C. engine) follows suction stroke, compression stroke, expansion stroke, and exhaust stroke. During the expansion stroke of a single cylinder four-stroke engine, due to the combustion of fuel in the blast chamber (i.e. cylinder), thrust is produced and this produced thrust pushes the piston downward.

The reciprocating motion of the piston in a downward direction rotates the crank for certain degrees during every 720 degree rotation.

[003] But due to the four-stroke cycle, the single-cylinder I. C. engine can add the power only once in a complete 720 degree of crankshaft rotation.

[004] Since the crankshaft and the flywheel of an I. C. Engine are keyed rigidly with each other, the expansion process tends to add a power generated by a power stroke indirectly to the flywheel.

[005] Also, when the hammer of mass 10 kg applied on a metal nail gradually, the nail doesn't get affected that much; but when the hammer with the same mass of 10 kg applied on nail suddenly, nail penetrates quickly.

[006] When the mass is applied suddenly then the force generated is much more than the force exerted by that same mass when applied gradually, in both applications mass remains constant, it means that at the instant of impact the gravitational energy get harnessed in the mass results in the generation of more force.

[007] In conventional power transmission using belt and pulleys, output shaft delivers a power output always less than the amount of power given as input due to losses in power transmission.

[008] The above mentioned shortcomings, disadvantages and advantages are addressed herein, as detailed below.

C) OBJECTS OF INVENTION

[009] The primary object of the invention is to provide a pulsed power transmission method and a device capable to transmit power in the form of power pulses.

[010] Another object of the present invention is to provide a pulsed power transmitting device less prone to wear and tear damage.

[011] Yet another object of the present invention is to develop a mechanical pulsed power transmission system capable to harness gravitational energy during power transmission process.

[012] These and other objects and advantages of the embodiments herein will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

A first heavyweight flywheel 107A and a second heavyweight flywheel 107B are capable to store more energy than a lightweight flywheel 102. A power receiving unit 113 comprises a first power receiving mechanism or system or device 109A and a second power receiving mechanism or system or device 109B. An input shaft 103, a first output shaft 108A, and a second output shaft 108B are supported by sets of bearings 124 capable to withstand under high temperature, speed, and thrust. Axis of rotation of an input shaft 103, first output shaft 108A, and second output shaft 108B lies in the same plane and parallel to each other. First pulse pulley 104A and a second pulse pulley 104B are mounted on the input shaft 103. Axis of rotation of a first pulse pulley 104A, a second pulse pulley 104B, and an input shaft is same. A prime mover 101 coupled to an input shaft 103, wherein a lightweight flywheel 102 is mounted on the input shaft 103 to deliver uniform rotational power. An axis of rotation of an input shaft 103 and a lightweight flywheel 102 is same. A first power pulley 106A and a second power pulley 106B are mounted on first output shaft 108A and second output shaft 108B respectively. A first pulse pulley 104A transmits power to a first power pulley 106A by means of at least one first V-belt drive 105A. A second pulse pulley 104B transmits power to a second power pulley 106B by means of at least one second V- belt drive 105B.

First output shaft 108A and a second output shaft 108B delivers uniform and continuous rotational power to a first power receiving mechanism or system or device 109A and a second power receiving mechanism or system or device 109B respectively. First power pulley 106A and a second power pulley 106B are conventional V-belt pulleys.

First pulse pulley 104A and a second pulse pulley 104B can transmit power either in clockwise or in an anticlockwise direction in the form of power pulses. Worn out and damaged first V-belt drive 105A and second V-belt drive 105B can be replaced easily like conventional V-belt power transmission system. A prime mover 101 is a mechanism or a device that generates rotational power as an output power and is not limited to an electric motor, a steam turbine, a hydro turbine, a gas turbine, a gravity-powered mechanism, a reciprocating internal combustion engine, human powered mechanism and the like. First pulse pulley 104A and a second pulse pulley 104B are positioned on the input shaft 103 by considering mounting positions of a first output shaft 108A and second output shaft 108B in such a way that, the gripping arc of a first pulse pulley 104A and a second pulse pulley 104B comes in contact with a first V-belt drive 105A and a second V-belt drive alternately. An Input shaft 103 receives continuous rotational power from a prime mover 101. An input shaft 103 transmits rotational power alternately to the first output shaft 108A and second output shaft 108B through a pair of first pulse pulley 104A and first power pulley 106A, and second pulse pulley 104B and second power pulley 106B respectively in the form of power pulses.

During power transmission process whenever a first V-belt drive 105A comes in a contact with the sliding arc 1 15 of a first pulse pulley 104A completely, then power transmission does not takes place between an input shaft 103 and first output shaft 108A resulting in generation of pause in power transmission getting between an input shaft 103 and first output shaft 108A till the gripping arc 1 14 of a first pulse pulley 104A again comes in a contact with a first V-belt drive 105A. Similarly whenever a second V-belt drive 105B comes in a contact with the sliding arc 1 15 of a second pulse pulley 104B completely, then power transmission does not takes place between an input shaft 103 and second output shaft 108B resulting in generation of pause in power transmission getting between an input shaft 103 and second output shaft 108A till the gripping arc 114 of a second pulse pulley 104B again comes in a contact with a second V-belt drive 105B. Adjacent power pulses getting transmitting from a first pulse pulley 104A and a second pulse pulley 104B to a first power pulley 106A and a second power pulley 106B respectively, do not overlap with each other; means that a second pulse pulley 104B starts to transmit power to a second power pulley 106B only after a transmission of a power between first pulse pulley 104A and a first power pulley 106A get complete. A power developed at a first output shaft 108A and a second output shaft 108B get stored in a first heavyweight flywheel 107A and second heavyweight flywheel 107B respectively. A first output shaft 108A and a second output shaft 108B continuously and uniformly delivers rotational power to the connected first power receiving mechanism or system or device 109A and second power receiving mechanism or system or device 109B respectively. The first power receiving mechanism or system or device 109A and a second power receiving mechanism or system or device 109B are mechanisms or systems or devices that needs a rotational power to operate. The first power receiving mechanism or system or device 109A and a second power receiving mechanism or system or device 109B can be but are not limited to an another pulsed power transmission system; means that a power developed by a first pulsed power transmission system can be used as an input rotational power to operate second pulsed power transmission system, an alternator, a generator, a vehicle powertrain, a mass lifting mechanism to store potential energy, a water pump set, an energy storage device charging system by means of an alternator or generator and the like.

[041] With respect to FIG. 3 and FIG. 4, a power developed at a first output shaft 108A and a second output shaft 108B can be combined to deliver a rotational power to a single power receiving mechanism or system or device 109C as shown in FIG. 4. At least one first sprocket 123A and at least one second sprocket 123B are mounted on first output shaft 108A and second output shaft 108B respectively. Axis of rotation of first output shaft 108A and first sprocket 123A is same. Axis of rotation of second output shaft 108B and second sprocket 123B is same. At least one first one-way sprocket 122A and at least one second one-way sprocket 122B are mounted on the third output shaft 108C, where a first one-way sprocket 122A and second one-way sprocket 122B can transmit power only in one direction, either in a clockwise or anticlockwise direction. Axis of rotation of a third output shaft 108C, first one-way sprocket 122A and second one-way sprocket 122B is same. First one-way sprocket 122A and second one-way sprocket 122B are mounted on the third output shaft 108C in such a way that both first one-way sprocket 122A and second one-way sprocket 122B transmits power in the same direction. Rotational power is transmitted from a first sprocket 123A to a first one-way sprocket 122A by means of at least one first chain drive 125A, and from second sprocket 123B to second one-way sprocket 122B by means of at least one second chain drive 125B. One-way power transmitting feature of a first one-way sprocket 122A and second one-way sprocket 122B allows third output shaft 108C to rotate continuously.

Power combined at the third 108C output shaft is then transmitted to a single power receiving mechanism or system or device 109C continuously and uniformly. A single power receiving mechanism or system or device 109C is a mechanism or a system or a device that needs a rotational power as an input power to operate. A single power receiving mechanism or system or device 109C can be but is not limited to an another pulsed power transmission system; this means that a power developed by a first pulsed power transmission system can be used as an input rotational power to operate second pulsed power transmission system, an alternator, a generator, a vehicle powertrain, a mass lifting mechanism to store potential energy, a water pump set, an energy storage device charging system by means of an alternator or a generator, a compressing system and the like. A power developed at a first output shaft 108A and a second output shaft 108B can be combined at the third output shaft 108C only when the rotating speed of a first output shaft 108A and a second output shaft 108B is equal or nearly same.
