Couplings

Product catalog summary

Overview:
Pintsch Bubenzer manufactures a range of flexible couplings designed for high-performance applications. These couplings are torsionally elastic, robust, and easy to maintain, capable of handling high dynamic loads. They are certified under DIN EN ISO 9001:2015.

Types of Couplings:

KLST / KST: Steel couplings that are torsionally elastic and fail-safe, transmitting torque via an elastic intermediate ring. They accommodate shaft misalignment and provide electrical insulation, suitable for temperatures from -35°C to +80°C, with short-term tolerance up to +100°C.
KLST-BS / KST-BS: Similar to KLST/KST but include a brake disc on the gear side to maintain brake torque when the motor is disengaged.
KLST-BT / KST-BT: Feature a brake drum on the gear side for maintaining brake torque when the motor is disengaged.
KL: Designed for high torque applications, offering easy maintenance and robust performance.

Technical Specifications:
Each coupling type includes detailed dimensions and technical data such as maximum torque (TKmax), nominal torque (TKN), maximum speed (nmax), and dimensions for various sizes. Couplings are available with different bore diameters and can be dynamically balanced according to ISO 1940 standards.

Applications:
These couplings are ideal for applications with high dynamic loads, providing damping of peak torques and vibrations, and ensuring electrical insulation between motor and gearbox.

Additional Services:
Pintsch Bubenzer offers verification of coupling selection, installation, and commissioning services. Detailed operating manuals and engineering drawings are available upon request.

Main Features:

Torsionally elastic and fail-safe design.
Torque transmission via elastic intermediate rings or buffers.
Replacement of elastic components without moving equipment.
Electrical insulation to prevent leaking currents.
Available in various sizes and materials, with options for dynamic balancing and special lengths.

Specifications:

Standard material for elastic components is Polyurethane (Vulkollan), suitable for temperatures from -35˚C to +80˚C, and short-term exposure from -40˚C to +100˚C.
Couplings are dynamically balanced according to ISO 1940 Grade: G 2.5; G 6.3.
Test certificates available according to DIN EN 10204-3.1.

Options:

Finish bored and keywayed hubs according to DIN 6885.
Unbored and pilot bored hubs.
Special material and length options for hubs.

Service and Support:

Detailed operating manuals provided with each order.
On-site installation and commissioning available by PINTSCH BUBENZER service engineers.
Engineering drawings available upon request.

Design and Features:
The couplings are designed for easy maintenance and high performance, featuring torsionally rigid torque transmission, high temperature resistance, and low wear. The construction includes hubs, brake discs, and geared sleeves, with ease of replacing brake discs without moving equipment.

Standards and Certifications:
The products are certified according to DIN EN ISO 9001:2015, ensuring quality and reliability. Compliance with other DIN standards for dimensions and material specifications is also mentioned.

Recommendations:
The document advises on the selection and installation of couplings, emphasizing the importance of fitting covers to prevent accidents. It offers options for custom dimensions and materials, and provides a detailed operating manual with each order.
