TAS Schäfer GmbH is ISO 9001 certified, ensuring high standards from development to delivery. They maintain a raw material stock to ensure short delivery times, even for customized solutions.
The product catalog includes hydraulic shrink discs, rigid flange couplings, and external clamping elements, used in industries such as wind energy, marine technology, and mining. Customized solutions are also available to meet specific customer requirements.
Products are used globally in applications like wind power, mining, materials handling, marine technology, drive technology, and hydropower. Hydraulic and mechanical shrink discs, flange couplings, and locking assemblies are integral to these industries.
The company supports renewable energy efforts, with products like hydraulic shrink discs used in wind turbines. They focus on innovative product development to reduce assembly times and enhance safety with products like friction springs and industrial buffers.
TAS Schäfer GmbH is distinguished by its commitment to quality, innovation, and customer satisfaction, maintaining a strong presence in the global market for shaft/hub connections.
The document details specifications for stainless steel products, focusing on shrink discs and flange couplings used in extreme conditions across industries like oil and gas, wood processing, food, paper, and packaging. Key products include shaft couplings, shrink discs, and hydraulic shrink discs, each with specific applications and benefits.
Shrink Discs (SHS) provide a backlash-free connection by pressing the hub onto the shaft, mainly used to transmit torque. Hydraulic Flange Couplings (FKH) ensure a rigid and backlash-free connection between shafts, capable of transmitting torque and absorbing bending moments.
Contact surfaces between shaft and hub must be free of grease, dry, and clean for proper operation. Functional surfaces are factory-equipped with lubricant, and additional grease is required for installation.
Nominal sizes range from 70 mm to 1,000 mm, with nominal torques varying from 6 kNm to 14,000 kNm. The pressure range is up to 400 bar for dismounting operations.
Customizable design for specific applications, rapid tightening and loosening capabilities, improved corrosion protection, and simplified handling.
Ensure proper surface quality and tolerances to maximize transmissible torque and minimize unwanted settling. Follow specified tightening torque values to avoid component stress.
The document provides detailed specifications for shrink discs, including calculations for transmissible torques and forces. It emphasizes the importance of selecting the appropriate shaft diameter and highlights that the transmissible torque is approximately proportional to the shaft diameter.
Key formulas are provided for calculating torque and axial force based on shaft diameter. The document includes equations for pressure changes due to radial forces and bending moments, emphasizing the importance of maintaining minimum and maximum pressure to avoid gap corrosion.
The document discusses the deformation of the hub due to radial forces and the importance of considering shaft stiffness and surface finish. Hollow shafts experience greater deformation and stresses.
The notch effect caused by radial pressure is discussed, with notch factors provided for both the hub and shaft. The document suggests design features to mitigate the notch effect and references standards for determining notch factors.
Design considerations for shrink discs are outlined, including variations in shaft diameter and the impact on transmissible torque. The document provides a detailed table of dimensions and specifications for different sizes of shrink discs.
The document includes ordering information for standard and strengthened ranges of shrink discs, with detailed specifications for each size. It also provides contact information for TAS Schäfer GmbH and notes compliance with ISO 9001:2018 standards.

Description of function SHS Shrink discs of the type SHS The main function of a shrink disc is the safe connection of a shaft with a hub by means of friction. For example, between a drive shaft and a transmission hollow shaft. The shrink disc generates a backlash-free connection by pressing the hub onto the shaft. This connection is mainly used to transmit torque. The shrink disc only provides the required forces, and transfers no forces or moments between shaft and hub by itself. It is not in the force flow. It is installed by sliding the shrink disc onto the hollow shaft and the subsequent...
