  • Dali Conical GearboxThe new concept

    Dears,

    Greetings, My name is Hassan Dali; Im the inventor of the new Conical My name is Hassan Dali; Im the inventor of the new Conical Gearbox and I would like to introduce my invention to you

    through this document.

    The European patent office filing date of EP 14003403.4 is 2.10.2014 . and published 6.04.2016 .

    The WIPO application date of PCT/SY 2015/000002 is 23.9.2015 .

  • What is the Conical Gearbox?

    It is a new concept in the world of gear boxes. It consists of two main shafts and several gears depending on how many ratios we need. It is also important to mention that the pattern of such gearboxes is that the ratios are a part of a series of calculations which entitle it strongly for industrial calculations which entitle it strongly for industrial uses, especially when changes are close to each other such as water pumps and electric generators etc.

    Its size and weight are less than any other types of gear boxes and as a result it will be cheaper and will be more compatible with the hybrid cars.

  • Conical gearbox features

    1. After hitting many obstacles in my research.

    2. So this gearbox is a dream come true.

    3. And heralds the birth of a new concept in the field of Gearbox.

    4. And now we are looking forward to see the gearbox installed in a vehicle. It does not matter which vehicle, electric, hybrid or conventional fuel usage. To be capable of giving the highest conventional fuel usage. To be capable of giving the highest possible efficiency, even for heavy duty usage. which will reduce fuel consumption.

    5. It could contain open numbers of speeds in a part of a series of calculations, will serve to get the maximum of either rotating speed or torque.

  • 6. It serves wider range of ratios than any other. The main target is to reduce engine RPM below than 2000 RPM in what ever the car speed is. Therefore:7. Car designers suppose replace the 1200cc motors volume instead of the 1600cc. Then reduce tank volume.8. The CGB reduces fuel consumption, noise and environment pollution due to reducing RPM of the engine. so it will extend motors life cycle. And lubricant oils will last for longer distances and longer time.9. It could has more than one input shaft and more than one out put 9. It could has more than one input shaft and more than one out put shaft, and each shaft has its own speed and could be changed separately. Knowing that it is in less weight, less volume, and less cost than others. 10. Users could choose his own favorite speeds and change in between, manually, automatically or tiptronic.11. This type could be used in Automobiles, electric generating units, Generating electricity from the wind or water flows, and where ever we need to change speeds. ...

  • In this prototype a benzene engine is rotating a rubber wheel, it circumference about 1 meter. A friction force is applied to the wheel.

    1. At the small gear for one minute driving the engine consumed 5 centimeters of gasoline and the number of cycles the wheel rotated was 209 turns and the distance the wheel passed was 209 meters.

    2. At the middle gear for one minute driving the engine consumed 5 centimeters of gasoline and the number of cycles the wheel centimeters of gasoline and the number of cycles the wheel rotated was 245.5 turns and the distance the wheel passed was 245.5 meters.

    3. At the large gear for one minute driving the engine consumed 5 centimeters of gasoline and the number of cycles the wheel rotated was 282.5 turns and the distance the wheel passed was 282.5 meters.

    4. The conclusion shows that, changing from one gear to the next gear in this prototype reduced fuel consumption by 12%.

  • Practical application:When CGB used in the field of electric generator. If we need to save energy, we have to reduce the motor rotations, in such case a problem of current specifications will occur by reducing the voltage and frequency values. but when using this type of gearbox a part of a series of calculations will serve to get the maximum of either rotating speed or torque. Consumers will choose their convenience.Five speeds gearbox showing how saving could be if 10 % is the saving between any two neighbors speedsIt will increase the efficiency of electrical power generating using traditional It will increase the efficiency of electrical power generating using traditional combustion engines.
