1. Flexible Couplings: These include POLY-NORM® and POLY couplings, which are maintenance-free, flexible, and feature axial plug-in capabilities. They are designed to be fail-safe and compact.
2. Gear Couplings: BoWex® gear couplings are torsionally stiff, maintenance-free, and available in single or double-cardanic designs. They are compact and feature axial plug-in capabilities.
3. Highly Flexible Shaft Couplings: EVOLASTIC® and BoWex® HEW Compact couplings are highly flexible, maintenance-free, and designed to be fail-safe with axial plug-in features.
4. Flange Couplings for I.C. Engines: These include BoWex-ELASTIC®, SINULASTIC®, and MONOLASTIC® couplings, which are flexible to highly flexible, maintenance-free, and compact with axial plug-in capabilities.
5. Laminae Couplings: RADEX®-N and RIGIFLEX®-N couplings are torsionally stiff, backlash-free, and maintenance-free, available in single or double-cardanic designs.
6. Pin & Bush Couplings: REVOLEX® KX-D couplings are flexible, maintenance-free, and fail-safe with compact dimensions and axial plug-in features.
1. DIN 740 Part II: Coupling selection is based on ensuring that the permissible coupling load is not exceeded during any operating condition. This involves comparing actual loads to permissible parameters.
2. Torque Specifications: Rated torque (TKN), maximum torque (TK max), and vibratory torque (TKW) are key parameters for coupling selection.
3. Environmental and Operational Factors: Factors such as temperature (St), starting frequency (SZ), and shock factors (SA/SL) are considered in the selection process.
An example calculation is provided for selecting a coupling for a connection between an IEC standard motor and a screw compressor. The calculation considers rated torque, peak torque, and environmental factors to ensure the coupling is sufficiently dimensioned.
1. Temperature Factors: Different materials and coupling types have specific temperature factors that affect their performance.
2. Operating Factors: These include application-specific factors such as those for construction machines, mixers, and food industry equipment.
3. Terminology and Definitions: Key terms and symbols related to coupling selection are defined to aid in understanding the selection process.
The document provides detailed specifications for coupling systems, particularly focusing on the ROTEX® GS series. It includes calculations for moments of inertia (JA, JL) and torque (TS, TKN) necessary for coupling selection according to DIN 740 Part II standards. The document specifies the maximum continuous torque, driving torque, and speed for servo motors, along with the ambient temperature and starting factors.
The document outlines the procedure for selecting the appropriate coupling based on the calculated torque requirements and the permissible friction torque. It emphasizes the need for the coupling to be dimensioned to prevent exceeding permissible friction torque during operation.
The coupling selection is guided by DIN 740 Part II, with specific factors such as shock on the drive side and starting factors considered. The document also references ATEX, UL, GOST, and other certifications for various coupling types.
Recommendations include selecting backlash-free, axial plug-in couplings for high-speed applications, particularly for connecting servo motors and main spindles in grinding machines. The ROTEX® GS series is highlighted for its suitability in these applications.
The document includes tables detailing the types and properties of flexible jaw and pin & bush couplings, including their torsional flexibility, damping capabilities, and maintenance requirements. It also provides displacement figures for different spider types and sizes, indicating maximum axial, radial, and angular displacements.
The document lists various applications for the coupling systems, including industrial gearboxes, pump industries, and high-pressure pumps. It highlights the versatility of the ROTEX® series in accommodating different industrial needs.
Key parameters such as torque range, temperature range, and material specifications are provided for different coupling types. The document stresses the importance of adhering to these specifications to ensure optimal performance and safety.
