Rathi Transpower Pvt Ltd is a full-fledged manufacturing set up, catering to coupling needs of every industrial sector. They manufacture every type of couplings for all types of conceivable drive applications. Their facilities are certified ISO 9001 with presence in every part of globe with offices in India, North America, Germany and Australia. Few manufacturers globally can offer such a vast variety of couplings, readily available through their global distribution system.

In today’s growing scenario, demands are raised worldwide for natural resources where conveyors are used in surface, underground mines, mineral-processing facilities, harbors and ports which routinely moves hundreds and thousands of tons per day. This demand upping the manufactures on limit of belt – conveying capacity, resulting in higher loads and in turn higher wears. For this higher-capacity, conveyors are often designed with reduced safety margins on the belt which requires greater drive system control to ensure maximum availability and reduce any unexpected downtime.

Hydrodynamic fluid couplings actively cushion motors, belts and gear reducers in such systems from torque overloads and torsional shock. They maximise power transmission and step lessly control torque, acceleration and operating speed. In addition, the “slip” when loaded beyond maximum capacity and effectively protect the driveline from harm. Perhaps, no single element contributes more to smooth belt-conveyor operation than a fluid coupling. The belt is often the most expensive part of a conveyor system, and couplings must protect that investment through smooth, dependable operation.

As mentioned above, hydrodynamic couplings by design transfer power with negligible wear and eliminate mechanical shocks in the drive chain. Rugged, robust and compact couplings of Rathi Lovejoy work dependably and ensure safe and reliable performance, even under the toughest environmental conditions.

Technology
Rathi Lovejoy Fluid coupling having technical collaboration with TRANSFLUID S.p.A. Italy, and works on Hydrokinetic principle. Both the impellers perform like a centrifugal pump and/or a hydraulic turbine. As the name implies, they hold a pre-set amount of fluid. They are filled before commissioning; the ratio of fluid volume to the overall volume of the coupling (called the fill level) affects output. Manually adding or removing fluid (when stopped) changes operating characteristics.

Lovejoy-India fluid couplings are inbuilt with the following advantages over others:
• Manufactured with Pressurised aluminum die castings: It ensures superior quality, increase in power to weight ratio and best aesthetics as compared to gravity die castings and sand casting fluid couplings.
• Standard design construction, fluid coupling is placed before to flexible coupling: It provides increase in life time for flexible coupling, in-turn down time is reduced and easy maintenance.

• Viton 2 lip oil seals are used to ensure zero oil leakage

Various fluid coupling versions are mainly differentiated by their internal volumetric chambers, and the means by which they automatically meter filling and emptying to influence start-up behavior. They generally don’t need external controls and provide seamless, trouble-free performance.

Did you know?
The specified operating conditions of a Rathi Lovejoy coupling can be monitored by a thermal operation control device and fusible safety plugs in the coupling housing provide additional protection against overheating and overload pressure.
