5. Needs Of Gearless Transmission ? Today’s world requires speed on each and every field.
Engineers are constantly confronted to the challenges of efficient transmission of power. Gears are costly to manufacture.
It is needed to further increase the efficiency of transmission which can not be done using geared transmission.
Gearless transmission mechanism is capable of transmitting power at any angle without any gears being manufactured. Gearless Power Transmission Using Elbow Mechanism 5

6. REVIEW OF LITERATURE Sr.No Name of Author Year of Publication Title of Publication Literatures Summary 1 Abdul Sazid Khan, Guide- Kheelraj Pandey. 2019 Design can be a small and lightweight piece of equipment that is capable of transmitting power at various angles without the use of gears. El-bow Mechanism devices are came to use for sending power however solid shafts are twisted. 2 . S.S. Pawar , Ankur Naidu, Panigopal Vallabhaneni 202 Have designed the link mechanism from the input shaft to output shaft to achieve perfect rolling and sliding pair of the mechanism. The transmission of power with minimum losses is the main criterion for calculating the efficiency of the engine 3 M. Lokesh , R. Ranjith Kumar , R. Revanth , K. Renugadevi 20 21 Gearless elbow mechanism setup with three elbow rods with obtuse angle of 120º for transmission of power in the wood cutting machine. The Gearless transmission is an apparatus for transmitting power at any desired angle between
the driving and driven shaft. Gearless Power Transmission Using Elbow Mechanism 6

7. WHAT IS GEARLESS TRANSMISSION ? Also called elbow mechanism.
It is an ingenious link mechanism of slider and kinematic chain principle.
Transmits power at 0 to 90° angle without utilizing gears. . Gearless Power Transmission Using Elbow Mechanism 7

8. WORKING PRINCIPLE Working Principle - Transmits the power between two shafts whose axes are at 90° degrees through bent links.
Three links slide relatively according to the motion given to input shaft.
Due to this, the rotational motion of input shaft is converted into sliding motion of links which is then converted to rotational motion of the output shaft. https://youtu.be/OxZZ9m2OxrQ?si=KI-Vrjcmk-CApYxV https://youtube.com/shorts/9Nk-MR-XNwE?si=NMJXBCWo6UTytbnd Gearless Power Transmission Using Elbow Mechanism 8

12. APPLICATION Tower clocks
Gang drilling (multi spindle drilling)
Lubrication pump for CNC lathe
Angular drilling between 0-90 degrees Movement of periscope in submarines
Used in vehicles (go-carts) Hand driven machines like juice makers, sheet machines etc. . Small and medium load transmission
Very useful in machine shop
Industrial application ..  GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 12

13. Geared v/s Gearless Transmission Geared Transmission Manufacturing methods: Costly
Manufactured on special
purpose machines
Complex calculations No interchangeability Causes of failure: Pitting, corrosion, erosion and fatigue have severe effect.
Replacement of entire gear set needs to be done. Gearless Transmission Manufacturing methods: Less costly
No need of special machines
Less calculations
Freedom of interchangeability Causes of failure: Pitting, corrosion, erosion and fatigue effect less severely.
Replacement of defected pin only. GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 13

14. Geared v/s Gearless Transmission Geared Transmission Lubrication and cooling: Complex system
Cooling is big issue Torque transmitting capacity: Used in high torque applications Different speed at any angle is not easily possible Gearless Transmission Lubrication and cooling: Simple
Easy to cool Torque transmitting capacity: Used in low torque applications Different speed at any angle is easily done GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 14

15. MANUFACTURING OF PARTS GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 15

16. ADVANTAGES More efficient than gear.
Complete freedom of interchangeability. Power could be transferred to any desired angle.
Ease of manufacturing.
Misalignment of shafts can be tolerated to some extent.
Simpler cooling system.
Low cost of manufacturing. Portability of parts.
Used to reduce maintenance of cost.
Quick response is achieved.
Easy to maintain and repair. No fire hazard problem due to over loading.
The speed of forward and reverse stroke is varied.
Continuous operation is possible without stopping. GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 16

17. LIMITATION Does not work at very low starting torque.
Improper hole drilling could pose much problem. Sudden load would cause mechanism breakdown. Links are to be replaced after certain cycle time. Speed ratio is always constant 1:1 Load carrying capacity of this unit is not very low. GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 17

18. FUTURE ASPECTS Torque bearing capacity can be improved. Flexible bent links may be used. Has a bright future in automation and robotics. Can be used in automobile industry.Note : By attaching bushes with drum then the chances of vibration may reduce and also overall weight of the mechanism is also reduced (by using drum with less thickness). The proper operation of bent links may obtained. GEARLESS POWER TRANSMISSION USING ELBOW MECHANISM 18
