Rathi Couplings excels in manufacturing gear couplings that deliver robust torque transmission for demanding industrial applications. These gear couplings from Rathi Couplings handle high misalignment and shocks, making them perfect for crushers, mills, and turbines where reliability counts most.
Understanding Gear Couplings Basics
Gear couplings consist of two hubs with external gear teeth meshed through a sleeve, often with lubricant for smooth operation. Rathi Couplings builds these with hardened steel gears for exceptional strength, accommodating up to 2 degrees angular and 0.05 inches parallel misalignment. As a leader in gear couplings, Rathi Couplings ensures crowned teeth that reduce edge loading and extend service life.
Operators turn to gear couplings when maximum torque matters more than flexibility, unlike elastomeric types. Rathi Couplings' designs shine in high-power setups, transmitting forces without slippage under full load.
How Rathi Couplings' Gear Couplings Perform
Rathi Couplings' gear couplings transfer power via interlocking spur gears lubricated with grease, minimizing friction and wear. The double-engagement style uses two sleeves for balanced loads, ideal for long shafts in generators. Single-engagement versions suit compact spaces like pumps.
Torque capacities reach 1,000,000 Nm in larger models from Rathi Couplings, with speeds up to 10,000 RPM after precise balancing. Lubrication intervals stretch to 6 months, but Rathi Couplings adds seals to keep grease in and contaminants out.
Vibration damping comes from slight backlash, protecting bearings from overloads during startups.
Varieties of Gear Couplings by Rathi Couplings
Rathi Couplings offers flexible gear couplings with nylon sleeves for lighter duties in fans and blowers, cutting weight by 30%. Fully geared models target steel mills, featuring continuous sleeves for max rigidity.
Spacer gear couplings from Rathi Couplings bridge gaps up to 3 meters in paper machines or marine drives. High-speed variants include API 671 compliance for oil platforms.
