Hysteresis Brakes and Couplings

Hysteresis Brakes and Couplings

Product catalog summary

Overview: The document provides comprehensive technical specifications and applications for permanent magnet hysteresis brakes and couplings, primarily used for tension control in wire, cable, and glass fiber applications. These components are noted for their wear-free operation due to the absence of friction.

Specifications: Hysteresis units operate by surrounding a hysteresis disc with magnetic assemblies. Torque is adjustable by altering the angle of pole overlap, with no contact surfaces ensuring indefinite maintenance of settings. Built-in bearings support sufficient bending moments on the shaft, and components can be customized to specific shaft dimensions.

Advantages: Key benefits include no breakaway torque, noiseless operation, and no wear due to the lack of friction. The precise grinding of high-energy magnets ensures friction-free movement and long durability.

Technical Data: The document includes tables listing various types of hysteresis brakes and couplings, detailing torque, inertia, power dissipation, maximum RPM, and weight. For example, Type 513-001 has a torque of 0.001 Nm and a maximum RPM of 4000, while Type 610-011 has a torque of 0.14 Nm and a maximum RPM of 1000.

Materials and Construction: Components are available in stainless steel, and the casing surface of some brakes is covered with a wear-resistant polyurethane layer. Hollow shaft options are available for certain models.

Applications: These components are used in power transmission fields, particularly for tension control in wire and cable applications, with potential for other applications in general drive technology.

Customization and Availability: Shaft and bore dimensions can be customized upon request, and many components are available in stainless steel for enhanced durability.

Clamping and Braking Systems: The document also covers clamping and braking systems used in industrial applications, including specifications for clamping pintles and constant tension brake assemblies, with operational procedures and safety notes.

Operational Procedures: Instructions are provided for locking and unlocking clamping pintles using a lever and tensioning wheel, suitable for both hardened and non-hardened shafts.

Safety Notes: A safety note mentions that the lever rotates with the system, indicating a need for caution during operation.

Technical Data: Includes technical data for torque transducers, such as accuracy class, repeatability, supply voltage, and temperature ranges.

Accessories: Information on accessories like flexible couplings and their dimensions, materials, and torque capacities is included.

Selection Criteria: Criteria for selecting the correct brake or coupling based on required torque, bending moment, and allowable heat dissipation, with reference to operating curves.

Specifications and Features: Permanent magnetic hysteresis brakes provide constant torque independent of RPM, unlike eddy current brakes. Torque increases to the adjusted value during approximately 25° of the first revolution and remains stable even at a standstill.

Operating Curves: Operating curves determine the safe operating range of the brakes, with areas indicating safe continuous duty, intermittent duty, and risk of overheating.

Applications: Ideal for tension adjustments in tensile wire applications, torque limiting, load torque simulation, and as couplings in spooler lines.

Mounting Arrangements: Brakes can be used as couplings for load protection or torque limiting, connected directly to a motor, or as clutches connected via a timing belt or gear.

Advantages: Hysteresis brakes require less maintenance than current-operated friction disc brakes, are easier to remove, and can be customized for specific applications, providing smooth operation with adjustable low torque and tension values.
