AX-BO® and RAFINEX®

Product catalog summary

Overview: The document outlines technical specifications and guidelines for selecting and sizing curved tooth couplings, specifically the AX-BO® and RAFINEX® series by RENK Aktiengesellschaft. It covers service factors, size determination, permissible loads, and design considerations for various applications.

Service Factors: Service factors (K1) are provided for different machinery types, essential for determining the appropriate coupling size. These factors vary based on machine type and operational conditions, such as excavators, mining equipment, and chemical plants.

Size Determination: Coupling size is determined by ensuring continuous power and torque conditions are met, using formulas that consider service factor, operating speed, and power factor.

Permissible Loads: Maximum permissible starting and short-circuit loads are specified. Higher angular or radial misalignments may require reduced operating speed.

Design Considerations: Key design considerations include maximum permissible bore diameter and verifying the power transmission capacity of the shaft-hub connection. Consultation with RENK is advised if keyway dimensions exceed DIN 6885 standards.

Coupling Types and Configurations: Various coupling configurations are described, including those with spacers and intermediate shafts. Formulas for radial misalignment and details on lubricant quantities, mass moments of inertia, and weights for different sizes are provided.

Dimension Tables: Detailed dimension tables for the AX-BO® and RAFINEX® series include torsional spring rates, permissible misalignments, and other critical parameters, aiding in selecting the correct coupling size and configuration.

Additional Notes: The document emphasizes considering the length and weight of spacers or intermediate shafts when determining maximum operating speeds. Guidelines for grease operation and mounting/dismounting procedures are also provided.

Specifications for RAH and RAZ Series: The document specifies torsional spring rates (CT) for the RAH series and provides formulas for calculating torsional spring rates of spacers and intermediate shafts in curved tooth couplings.

Formulas and Calculations: Formulas for calculating torsional spring rates for different configurations are provided, including specific calculations for the RAH, RAZ, and RAG series.

Data Tables: Tables list torsional spring rates for different coupling sizes and configurations, providing values for CT1 and CTR for the RAZ series, and CT for the RAG series.

Key Considerations: Deviations in shaft diameters have an insignificant influence on the overall torsional spring rate in the hub length area. No minimum lengths are prescribed for intermediate shafts, unlike couplings with spacers.

Contact Information: Contact details for RENK Aktiengesellschaft, Rheine Works, including phone, fax, email, and website information, are provided.

Catalog excerpts

Depending on design and size,an additional lubricant quantity must be taken into account for curved tooth couplings withspacer. The length L ist the pri-mary determining factor here. The table thus contains the required additional quantities for all sizes of the constructionseries RAZ.One value in each case refers to the whole spacer for the length L = L The maximum permissible static radial misalignment depends on the permissible angular misalignment and onthe distance between the toothcenters of both coupling hal- ves. This distance is variable for couplings with spacer orintermediate shaft....
