MULTI MONT SELLA - Torsionally flexible claw couplings

Product catalog summary
Overview
The MULTI MONT SELLA product catalogue by REICH focuses on flexible claw couplings tailored to meet specific customer needs. It highlights the company's dedication to customer satisfaction, flexibility, quality, and timely delivery.
General Technical Description
Since 1958, MULTI MONT SELLA couplings have been torsionally flexible, covering a torque range from 63 Nm to 1,000,000 Nm. They are designed for various power transmission needs, allowing easy radial element changes without moving machine parts axially.
Advantages and Uses
Benefits include displacement compensation, impact and vibration damping, increased productivity, breakdown resistance, and maintenance-free operation. Suitable for explosive atmospheres, they offer diverse designs through modular construction.
Standard Types
The catalogue lists several coupling types, including shaft couplings with taper bush, flange couplings, separable flange couplings, brake disc couplings, and brake drum couplings, each designed for specific applications with easy maintenance and assembly.
Technical Data
Detailed technical data for various coupling sizes include nominal torque, maximum torque, dynamic torsional rigidity, and permissible speeds. It also outlines materials used for different components, emphasizing corrosion protection and customized solutions.
Materials
Standard materials include cast iron for coupling hubs, with options for special material specifications. Proper dimensioning of connections is crucial to avoid inadmissible loads on components.
Flexible Coupling Elements
The catalogue details flexible elements used in couplings, their material composition, permissible temperature ranges, and features like abrasion resistance and torque transmission capacity.
Conclusion
The catalogue provides comprehensive information on flexible claw couplings, emphasizing adaptability, efficiency, and suitability for a wide range of applications, including explosive environments.
Specifications
Specifications emphasize selecting the appropriate coupling size to ensure permissible load limits are not exceeded. For drives with vibratory torques, a full torsional vibration analysis is recommended.
Procedures
Includes a formula for calculating nominal and maximum torque, considering factors like temperature and frequency, with a calculation example for selecting the appropriate coupling size.
Standards and Norms
References DIN ISO 21940 for balancing grades and DIN 6885/1 for keyway dimensions, mentioning taper bushes for easy assembly and disassembly.
Recommendations
Recommends verifying coupling selection through torsional vibration analysis for machinery with periodic excitation and considering service factors like temperature and starting frequency.
Tables and Data
Extensive tables detail coupling sizes, dimensions, and load classifications for various machinery types, with specific data on engine power, torque, and coupling size assignments.
Critical Information
Key parameters include nominal torque, maximum torque, and continuous alternating torque, which must be calculated and verified against operational conditions.
Dimension Tables
Lists coupling sizes with dimensions critical for selecting the appropriate coupling for specific applications.
Weights and Moments of Inertia
Includes data on weight and moment of inertia for each coupling type, essential for understanding dynamic performance.
General System Details
Outlines environmental conditions, load types, starting frequency, ambient temperature, and shaft displacement considerations for selecting the right coupling.
Balancing and Drive Side Information
Details on balancing without keyway, balancing grade, speed, and drive side specifications to ensure optimal performance.
Notes
Emphasizes adherence to copyright laws and prohibition of unauthorized distribution or reproduction.
Industrial Solutions
Covers industrial solutions including power generation, mobile applications, test benches, pumps & compressors, industry, and marine engineering.
