“Crank Less Reciprocating Machine”

Construction of Conventional Reciprocating Machine
A conventional reciprocating machine consists of a crank shaft and connecting rod mechanism for converting reciprocating action of the piston into rotary and viceversa.Internal combustion engine, reciprocating pumps, reciprocating compressors, etc are examples of conventional reciprocating machine.
In internal combustion engine, due to the ignition of fuel, piston will reciprocate and this reciprocating action of the piston can be converted to rotary by crank shaft and connecting rod mechanism. In other reciprocating machine like air compressor, pumps and refrigerator compressors, etc an external motor drive the crank shaft and as a result of this piston reciprocate inside the cylinder and the system works.
As we all know that crank shaft and connecting rod mechanism is common for all reciprocating machine, we got an idea of replacing crank shaft and connecting rod mechanism by a simple sine wave grooved shaft mechanism and this mechanism can replace crank shaft and connecting rod and hence the new innovative technology is applicable for all existing reciprocating machine.
The conversion of reciprocating motion into rotary motion is prevailing in many machine of present day use. Since the design and fabrication of Internal Combustion engine is more involved and hence we plan to develop an air compressor with the new technology as the first stage.
PRINCIPLE INVOLVED IN THE INNOVATION

In our invented crank shaft less reciprocating machine sine wave grooved shaft is one of the main components. Since it does the purpose of crank shaft and connecting rod, both shafts can be replaced by single sine wave shaft.

The Sine Wave Shaft is named because, sine wave shaped groove is carved on its periphery. The amplitude of the groove determines stroke length of the piston. When amplitude of the groove increases, stroke length also increases and when amplitude of groove decreases stroke length also decreases. Designing of amplitude of sine wave is closely related with diameter of sine wave shaft.

In the internal combustion engine, piston gets the power due to the ignition of the fuel and it reciprocate. At this time balls in the ball holder will travel through the sine wave shaped groove provided on the periphery of sine wave shaft. Because of it, this shaft will rotate and useful power (rotation) will be delivered from the end of the shaft.

In other reciprocating machines like air compressors, pumps, refrigerator compressors etc., external drive is given to the end of sine wave shaft from an electric motor. When motor rotates sine wave shaft also rotates. At this time balls in the ball holder will travel through the groove of sine wave shaft and as a result of it ball holder along with piston move up and down or piston reciprocate inside the cylinder and the system will work.

ADVANTAGES OVER KNOWN ALTERNATIVES

1. The invented Sine Wave Shaft Technology can successfully replace
crank shaft and connecting rod mechanism used in the existing reciprocating machine technology.

2. The Sine Wave Shaft engines are more compact, having less number of parts, less weight, vibration and run very smoothly when compared to crank shaft engines. Also it reduces the wear and tear due to friction.

3. Now huge internal combustion engines are being used in Ships, Trains and heavy Generators. If we utilize the new technology in the above engines, it will reduce the engine size, weight, noise and vibration very considerably without compromising engine cubic capacity.

4. When considering the above factors, sine wave shaft engines are more efficient than the crank shaft engines.









SCOPE FOR COMMERCIALIZATION, EMPLOYMENT GENERATION

1. Since the sine wave shaft engine technology is simple, efficient,
economical, compact and a best alternative technology than
crank shaft engine, it has lot of chances for commercialization,
globally.

2. Now our new technology is in the infant stage. Wide range of
scope for research and development is possible in future .
