Brief description of the drawings:
The invention will described below with reference to an example of an embodiment of the drawings:
Fig. 1 : Shows block diagram of the system for generating electrical energy in accordance to the present invention.
Fig. 2 : Shows exploded view of the system for generating electrical energy.
Fig. 3 : Shows perspective view of the high speed gearbox used in the system of Fig. 1. Detailed description of the drawings:
Referring to figure 1 , the system for generating electrical energy in accordance to present invention is illustrated. The system includes starter ( 10), motor (20), a high speed gearbox assembly and an alternator (80).
The starter (10) starts the whole mechanism by initiating the running of the motor (20). The motor (20) is connected to the gearbox assembly through V belt (30) to drive the gearbox assembly. The v-belt transmits the motion to the gearbox assembly.
The high speed gearbox assembly transmits the mechanical energy generated by the motion of the motor (20) to the alternator (80). The gearbox assembly further enhances the mechanical energy by means of high speed. The alternator (80) is connected to the gearbox assembly through V belt (31). The alternator (80) converts mechanical energy passed to it by the gearbox assembly into electrical energy.
Referring to figures 2 and 3, the gearbox assembly mainly includes the following components: four chain sprocket assemblies (50, 51 , 52, 53)
dual pair of helical gears (62, 63, 64, 65)
a pair of crown gears (60, 61)
a pair of PV central gears (70, 71)
a pair of worm gears (68, 69),
a pair of bevel gears (66, 67)
four rods (40, 41 , 42, 43).
The rod (40) rotatably accommodates the chain sprocket mechanisms (50, 51). The motor (20) is connected 'to rod (40) through v-belt (30). The rod (41) accommodates the helical gears (62, 63). The rod (42) rotatably accommodates the helical gears (64, 65), the chain sprocket mechanisms (52, 53) and the crown gears (60, 61). The rod (43) rotatably accommodates the PV central gears (70, 71) along with the pair of worfn gears (68, 69) and bevel gears (66, 67). The chain sprocket mechanisms (50, 51 , 52, 53) provide transmission of the motion from motor (20) to all gears.
The teeth on helical gears (62, 63, 64, 65) are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement. This gradual engagement makes helical gears operate much more smoothly and quietly. Because of the angle of the teeth on helical gears, they create a thrust load on the gear when they mesh. The helical gear provides high speed.
In the crown gears (60, 61) the pitch cone angle is 90 degrees. The crown gears (60, 61) mesh with the bevel gears (66, 67). The crown gears (60, 61) control the speed.
In the bevel gears (66, 67) the axes of the two shafts intersect and the tooth- bearing faces of the gears themselves are conically shaped. The bevel gears (66, 67) are mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone. The bevel gears (66, 67) increase the speed.
The worm gears (68, 69) control the speed and load from the bevel gears (66, 67). The central PV gears (70, 71) increase the speed up to 150-200 RPM. According to one of the embodiment of the invention, the system for generating electrical energy may includes energy storage device (90) which is connected to the alternator (80) for storing the electrical energy generated by the alternator.
The various materials used for gears may include a wide variety of cast irons, non ferrous material & non - metallic material. The selection of the gear material depends upon: i) Type of service ii) Peripheral speed iii) Degree of accuracy required iv) Method of manufacture v) Required dimensions & weight of the drive vi) Allowable stress vii) Shock resistance viii) Wear resistance.
Working of the present invention:
The starter (10) initiates the running of the motor (20). The running motor (20) runs the gearbox assembly through v-belt (30). The v-belt (30) transmits the motion to the chain sprocket mechanisms (40, 41 , 42, 43) which in turn transmits to various gears. The gears (60, 61 , 62, 63, 64, 65, 66, 67, 68, 69, 70, 71) are arranged and operatively connected with each other (refer figures 2 and 3) to ensure high mechanical energy at the output of the gearbox assembly. It also ensures high speed up to 1200- 1500 RPM at the output. The mechanical energy is then given to the alternator (80). The alternator (80) converts mechanical energy into electrical energy.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. It. will be understood by those skilled in the relevant art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
