How does the torque converter in the automatic transmission work. When the output torque of the fluid coupling exceeds the breakaway starting torque of the driven machine point d, the driven machinery gradually accelerates right half of. Many flexible couplings use fixed position flexible metallic, rubber or plastic elements, such as discs or bushings, that rotate with the shafts and absorb misalignment. Flender fludex couplings from siemens are hydrodynamic fluid couplings operating according to the fottinger principle. Fluid coupling, the principles of operation youtube. Electric motor characteristic curves with and without fluid coupling. Fluid coupling with a flexible coupling on the motor side. Preventive maintenance is especially important with hydraulic products. This page contains information on elecon fluid couplings that are energy efficient, and providing soft start ability to a motor to safeguard the gearbox and motor. We manufacture millions of standard products while developing tailormade components for you as well. Proper installation, maintenance and operation procedures must be observed. Construction, working, operation and maintenance of fluid couplings. Proper installation, maintenance and operation procedures must be.
The fluid coupling with inner wheel drive is driven via the hollow shaft. Installation and maintenance manual eleconhydrokinetic fluid coupling traction type. The high pressures and temperatures associated with hydraulics make hose and fitting maintenance as well as selection critical. If done correctly, the risk of injury andor excessive, costly downtime decreases. Using the mounting spindle and the thrust disc, the turbo coupling is mounted on the shaft, fig. Other coupling types are flexible couplings and fluid couplings. Assembly check, commissioning and maintenance report. With a fluid coupling installed, however, the torque to the driven machine starts at zero point c and gradually increases as the coupling impeller accelerates to point d. It is imperative therefore to provide each mechanic with a copy.
Fluid couplings or hydraulic couplings work on the hydrodynamic principle. Fluid couplings these instructions must be read thoroughly before installation or operation. The coupling hub must press against either the shaft. A fluid coupling is a hydrokinetic transmission unit comprised of three main. For a selection of permissible oils and oill filling capacities please refer to page 23. Construction, working, operation and maintenance of fluid. In drives consisting fluid couplings, there is no mechanical contact between the driver. The rotofluid fluid coupling is designed to provide your plant with optimum.
