Working Principle of Fluid Coupling

Fluid couplings are hydrodynamic devices that transform the energy from one shaft to another with a flexible hose while transmitting torque and ensure flexible transmission between driver shafts. The coupling uses hydraulic oil or water as its medium of transformation, which works best because it can transfer rotating mechanical energy between two different types of shafts without issue. Due to this, they are well capable of reducing vibration, increasing speed, load-sharing etc. 

During the whole operation, they use a small volume of transmission fluids, such as oil or water, confined to an outer flexible chamber and contained by bearings mounted on two rotatable shafts. The continuous circulation of fuel between the impeller and runner form a path like a helical spring. 

The torque generated by one of the rotating shafts gets transmitted via hydraulic pressure forces into the bearing surface at the point where it gets in contact with its companion sleeve (outer housing). At the time of contact, it generates shear stress between the two points that transmits angular momentum through both sleeves without any relative motion. Moreover, The device allows a controlled amount of slip between input and output, with zero physical contact between the drive and driven shaft. The driving turbine stays attached to the driven machine, transmitting power hydraulically in an efficient manner without wearing out either component. Furthermore, the process consumes less time while building a larger machine that compels high speed to operate efficiently.  And as the drive shaft eliminates all physical contact with its driven counterparts, rely on the hydraulic transmission which enables the system for an unlimited number of adjustment as needed depending on how fast rotation speed is required for the work. 

The apparatus also makes use of a hydraulic brake system that has been designed to efficiently transmit energy without any wear and tear. Hence, if the acceleration time is needed to expand they can do it as their engines have high torque curves and low compression ratios; both excellent features for this type of vehicle which needs instant response times combined with long intervals before needing another startup. 

Advantages of fluid coupling

There are varied advantages of fluid coupling, some of them are

  • As the fluid coupling is capable of providing stable acceleration of shafts, it gives smoother power transmission even in extreme conditions.
  • Engine can starts unloaded
  • It has overload protection as the coupling can liberate the driver by automatically draining the oil-filled blowing off the fusible plug. 
  • Due to the resting torque feature, the coupling is more stable and produces less or almost no vibration and noises during the power transmission. 
  • By altering the amount of oil filled in the container, the intensity of torque can be modified simultaneously.  
  • The fluid coupling can either be used as a vertical and horizontal application. 
  • The pump wheel and turbine wheel don’t have any mechanical contact, which prevents them from undergoing any frictional wearing on them.
