Shaft Clamping Elements

Product catalog summary
Company Overview: T.D. Cross Ltd., formed in 1984 from the merger of T.D. Cross and Morse Chain, is a leader in the Power Transmission Industry. The company manufactures roller chains, sprockets, gears, and other power transmission equipment, adhering to BS EN ISO 9001 standards.
Product Overview: Cross Shaft Clamping Elements are designed for connecting transmission equipment to shafts using frictional forces. They ensure precision torque transmission without backlash and are easy to assemble and disassemble, offering an alternative to traditional methods like tapered bushes and hydraulic clamping systems.
Advantages: These elements are easy to assemble and disassemble, simplify manufacturing, have a long fatigue life, transmit high torque, and resist wear and contamination. They also provide overload protection and sealed joints for gastight applications.
Selection Criteria: Key factors include shaft diameter, hub diameter, drive torque, axial thrust loads, shaft speed, and operating temperature. The document provides formulas for determining minimum hub diameter and maximum hollow shaft bore.
Installation and Maintenance: Installation requires only a torque wrench, and the elements are maintenance-free once assembled. They ensure true running and do not mark shafts, facilitating easy component disassembly and assembly.
Technical Specifications: Detailed specifications are provided for various clamping elements, such as Type RCK 15 for standard hubs and Type RCK 70 for high torque units, along with recommended tolerances and surface finish requirements.
Specifications: The document lists clamping elements like RCK19, RCK20, RCK25, and RCK95, detailing dimensions, torque capacities, axial forces, and weights, each designed for specific applications.
Installation Procedures: Step-by-step instructions are provided for installation and removal, including cleaning contact surfaces, aligning hubs, and tightening screws in a specified sequence. Specific instructions are given for types like RCK10, RCK19, RCK20, and RCK95.
Standards and Recommendations: The document emphasizes using clean, thin, unmodified mineral oil for lubrication and specifies recommended tolerances for shaft diameters and surface finishes.
Technical Data and Tables: Tables include technical data for each clamping element type, detailing dimensions, torque capacities, and axial forces, along with conversion factors and formulae for power transmission calculations.
Key Recommendations: The document advises against using clamping elements as flexible couplings, stresses the need for proper bearing support for radial loads, and highlights the benefits of larger screws and single block designs.
