2. Characteristics of Rathi_Ringfeder Tyre Couplings RTP/RTPS
– Manufacturer brand: Rathi-Ringfeder/India.
Outstanding features:
+ Tyre Coupling RTP/RTPS Torque transmission through polyurethane tyre shear.
+ Torque is transmitted through the polyurethane tyre ring operating under a shear mechanism.
This structure helps reduce vibration, absorb shock loads, and protect motors and gearboxes.
+ Split tyre design – easy maintenance: The tyre is divided into two halves and bonded to metal brackets. This design allows the tyre to be replaced without removing the hubs or shafts.This helps reduce downtime and lower maintenance costs.
+ High shaft misalignment compensation capability: The tyre coupling can compensate for: angular misalignment, radial misalignment, and axial misalignment. This helps reduce stress on bearings and machine shafts.
+ Suitable for multiple shaft sizes: The Tyre Coupling RTP/RTPS series supports a wide range of shaft bore sizes. Maximum bore ranges from 28 mm to 123 mm. This makes it suitable for drivetrain systems ranging from small motors to large industrial equipment.
+ Durable polyurethane material: The tyre is made from high wear-resistant polyurethane, providing excellent durability, resistance to repeated loads, long service life, and strong fatigue resistance.
