New Turbostart Hydromechanical Jolly Couplings

The worldwide patented Jolly hydromechanic coupling is a fitting of outstanding importance, which is widely used in modern transmissions. The Jolly coupling makes it possible to start high inertia loads gradually using three phase squirrel cage asynchronous motors, which demand constant continuous running however the load changes.

The Jolly Coupling is unique in combining the advantages of both fluid and mechanical device to provide fuIl protection, yet save substantially on capital, maintenance and costs.

Benefits

Soft starts (fig. C)
Dampens shock loads.
Energy savings by reducing initial starting current using a smaller motor according to the demand power at the rated speed (fig. D)
Varying the quantity of fluid makes it easy to match motor to drive requirements and provides optimum acceleration times.
Optional reservoir permits extended startup time.
No slip at full speed and no heat generation.
Optional temperature-limiting fusible plug provides protection in case of prolonged overloads.
Output speed kept at a constant level and in any case the same as the motor.
No wear and fatigue on mechanical lockup device.
No maintenance required but periodic oil change.
