2. Features and Types of KTR Flange Coupling SINULASTIC® B

2.1. Key Features

– Manufacturer: KTR / Germany.
– The KTR Flange Coupling SINULASTIC® B is a highly flexible flange coupling developed by KTR Germany to transmit torque, dampen torsional vibrations, and compensate for shaft misalignment in industrial drive systems, particularly those powered by internal combustion engines.
– The coupling combines a disc-shaped elastomer element with a flange and hub assembly designed for axial plug-in installation. This configuration supports reliable power transmission under torsional vibration conditions while facilitating installation and maintenance.
– The KTR Flange Coupling SINULASTIC® B features a linear torsional stiffness characteristic and incorporates a BoWex® toothed engagement design, allowing convenient axial assembly and compensation for axial, radial, and angular shaft misalignment.
– The SINULASTIC® B series is available in five standard sizes, ranging from size 20 to 180, with a rated torque range of 1,750–22,000 Nm, maximum rotational speeds of 2,400–3,800 rpm, and maximum shaft bore diameters of up to 240 mm, depending on the coupling size and elastomer configuration.
– The coupling supports various shaft connection methods, including keyed connections, splined connections, interference fits, and clamping hubs. It is also compatible with flange connections according to SAE J620, as well as certain special flange dimensions.
– With an allowable axial displacement of ±2 to ±4 mm, radial displacement of 0.8–1.5 mm, and angular misalignment of 0.6°–1.0° at 1,500 rpm, the SINULASTIC® B is a suitable option for consideration in diesel generator sets, reciprocating pumps, reciprocating compressors, and other drive systems subjected to torsional vibrations.
– Proper coupling selection must consider the operating power, rotational speed, load characteristics, and torsional vibration analysis of the complete drive system.

2.2. Construction of KTR Flange Coupling SINULASTIC® B

-The KTR Flange Coupling SINULASTIC® B consists of two main assemblies:
+ Elastomer Element: Consists of a flange ring and a rubber elastomer element vulcanized and bonded to the outer ring structure. This component receives and transmits torque while damping torsional vibrations generated during operation.
+ Hub: Connects to the shaft of the driven equipment. The hub engages with the elastomer element through a toothed connection, allowing axial plug-in assembly.
Operating Principle
– When the engine operates, torque is transmitted from the flywheel through the flange, elastomer element, and hub to the driven shaft.
– During torque transmission, the rubber element undergoes elastic deformation, helping reduce the effects of torsional vibrations.
– The coupling’s approximately linear torsional stiffness characteristic supports engineering calculations and coupling selection based on the dynamic behavior of the complete drive system.

2.3. Elastomer Materials for KTR Flange Coupling SINULASTIC® B

KTR offers three main elastomer material groups for the KTR Flange Coupling SINULASTIC® B:

Elastomer Material	Technical Characteristics
Natural Rubber (NR)	Available in different hardness grades to meet specific torque transmission and torsional stiffness requirements.
Ethylene Propylene Diene Monomer (EPDM)	An alternative elastomer material for suitable temperature and environmental operating conditions.
Silicone Rubber (SI)	An option for applications with special temperature requirements and elastomer performance characteristics.

– According to the previously provided SINULASTIC® catalogue, NR compounds are specified with temperature limits of up to 100°C, while EPDM and silicone elastomers may be rated for temperatures of up to 120°C.
– However, the SINULASTIC® B operating and assembly instructions specify a temperature range of -30°C to +80°C in the troubleshooting section.
– Therefore, it should not be assumed that every SINULASTIC® B configuration is suitable for continuous operation at 120°C. The permissible operating temperature must be verified according to the specific elastomer part number and actual operating conditions.

3. Applications of KTR Flange Coupling SINULASTIC® B

– The KTR Flange Coupling SINULASTIC® B is primarily intended for drive systems powered by internal combustion engines, particularly applications requiring torsional vibration damping and compensation for shaft misalignment.
– Typical applications to consider include:
+ Diesel Generator Sets: Connects diesel engines to generators, helping reduce the transmission and effects of torsional vibrations.
+ Reciprocating Pumps: Suitable for consideration in drive systems subjected to cyclic torque fluctuations, where torsional vibration analysis is required before coupling selection.
+ Reciprocating Compressors: Used in drive systems experiencing variable loads and significant torsional vibrations.
+ Diesel Engine and Gearbox Assemblies: A potential solution for applications requiring a flange-to-shaft connection with shaft misalignment compensation.
+ Long-Shaft Drive Systems: The BoWex® toothed engagement design provides connection options and misalignment compensation capabilities that may be suitable for certain long-shaft drive configurations.
– These applications are technically relevant examples for evaluating the SINULASTIC® B coupling. However, they do not imply that the coupling is automatically compatible with every machine or drive system within these categories.
– Final selection must be based on the required torque, rotational speed, operating conditions, shaft connection dimensions, and torsional vibration analysis.
