Abstracts: A Fluid coupling is a hydrodynamic device used to transmit rotating mechanical power. It has been used in automobile transmission as an alternative to mechanical clutch. It also has widespread application in marine an industrial machine drive where variable speed operation and controlled start of without shock loading of the power transmission system is essential. This project revels the design and manufacturing of fluid coupling components and the hydraulic fluid. In this work first of prepare a design and part modeling of fluid coupling, assembly made in Pro-E software. Then prepare a practical working model for checking the performance of fluid coupling. Finally the practical model check with various fluids which has different properties used in fluid coupling made different speed and power output for various situations.
A fluid coupling is a hydrodynamic device used to transmit rotating mechanical power. It has been used in automotive transmissions as an alternative to a mechanical clutch. It also has a widespread application in marine and industrial machine drives, where variable speed operation and / or controlled start-up without shock load of the power transmission system are essential. In this work of revision, a mathematical model is made and a model of practical work is developed. For checking the fluid coupling parts, the assembly made in the Pro-E software and analyzed for the static structure in the so-called "ANSYS" approach.
The fluid coupling is the device that is operated without mechanical connection between two axes. Coupling occurs only with fluid; here the power is transmitted by means of a fluid. The fluid coupling operates according to the hydrokinetic principle; allows the use of an I.C engine or electric motor with the advantages of simplicity, robustness and low operating costs. The transmitted torque is directly proportional to the amount of fluid in the unit and therefore is very simple, varying the oil fill, to match the coupling to the exact requirements of the drive machine.
In a typical automobile fluid coupling is more commonly called torque converter. The torque converter is screwed onto the engine via the flywheel or starter ring and attached to the transmission input shaft. From there, directly power and move the vehicle. Many variables are taken into account in the design of this fluid coupling, including vehicle weight, torque, power, optimum speed of operation and use. All factors are carefully considered when choosing the appropriate locking speed of the fluid coupling and the locking speed.
