Locking Assemblies & Bushes

Product catalog summary
Overview: The document provides comprehensive technical specifications and guidelines for mechanical components such as locking assemblies, bushes, clamping bushes, and shrink discs. It includes details on dimensions, materials, torque, and mounting instructions.
Locking Assemblies & Bushes: This section details specifications for locking assemblies and bushes, including self-centering and non-self-centering types. It includes calculations for minimum hub diameter and discusses transmittable torque and axial force ranges.
Taper Bushes: Information on taper bushes includes selection tables and specifications for various sizes, with mention of interchangeability with Taper Lock® bushes.
Clamping Bushes: Specifications include dimensions, torque, and maximum axial force, with mounting instructions emphasizing the need for oiling the shaft and bore before assembly.
Shrink Discs: This section covers inner diameter ranges and suitability for different shaft diameters, along with transmittable torque and thrust capabilities.
Custom Solutions: The document invites inquiries for custom-made parts, highlighting the availability of various sizes and materials, including stainless steel options.
Key Specifications:
  • Materials: Components are available in cast iron and steel, with specified tensile strengths.
  • Dimensions: Detailed tables provide dimensions for various components, including bore diameters and lengths.
  • Torque and Force: Specifies torque and axial force capabilities for different components, with values ranging from low to very high.
Mounting Instructions: Specific instructions for mounting clamping bushes are provided, highlighting proper tightening techniques and tolerances.
Specifications: Outlines specifications for clamping bushes, including permissible keyways in hubs and shafts, and the requirement for a gap between the flanges of the clamping bush. Pressure between the shaft and clamping bush is approximately 90 N/mm², and between the hub and clamping bush is 80 N/mm² at around 20°C. Maximum ambient temperature for use is 85°C.
Procedures: Before mounting, the shaft and bore should be oiled. Locking screws should be tightened alternately by 180° and loosened similarly. Clamping bushes are suitable for shaft tolerances h8 to k6 and bore tolerances H7. Detailed fitting and removal instructions emphasize maintaining a gap between the ends of the clamping bush.
Standards and Tolerances: Specifies tolerances and surface finish requirements, with a maximum allowable surface finish of Rt max 16 µm (Ra 3 µm - Rz 13 µm). Shaft tolerance is h8, and hub tolerance is H8. No axial movement of the hub relative to the shaft during screw tightening.
Recommendations: For applications requiring both torque and axial force transmission, a specific table must be referenced. Highlights the importance of using the correct tightening torque for screws to ensure proper function.
Data Tables: Extensive tables list various clamping bush models, their dimensions, set screw specifications, and performance metrics such as starting torque, torque, thrust, and contact pressures. These tables provide detailed technical data for selecting the appropriate clamping bush for specific applications.
Specifications: - Shaft tolerance: h8; Hub tolerance: H8
- Maximum allowable surface finish: Rt max 16 µm (Ra 3 µm - Rz 13 µm)
- High torque and limited installation time
- Economically advantageous applications
- Interchangeable with WMH series 298-002-…
Axial Movement: During screw tightening, the hub may experience slight axial movement relative to the shaft.
Locking Assemblies - Self-centering: Available in various sizes with specific torque, thrust, and contact pressure values. Custom solutions available upon request.
Calculation of Minimum Hub Diameter (DM): Formula: DM calculation uses a specific formula considering the coefficient K. Coefficient K varies based on application type and material. Example provided for WMH locking assembly type 298-006-060.
Table of Coefficient K: Lists coefficients for different materials and application types. Coefficient values depend on hub pressure and yield point of materials.
Shrink Discs and Trantorques: Detailed specifications for shrink discs and trantorques, including torque values, axial forces, and tolerances. Includes tables with measurements and part numbers for various sizes and configurations.
Procedures: Instructions for installation and dismantling emphasize the importance of clean, oil-free contact surfaces. Specifies no axial movement of the hub relative to the shaft during screw tightening.
Standards and Tolerances: Maximum allowable surface finish is Rt max 16 µm, with specific shaft and hub tolerances outlined for different diameter ranges. Concentricity is maintained at 0.06 mm, and temperature limits range from -34°C to +200°C.
Recommendations: For larger sizes or customized solutions, contact is advised. Provides recommended hub outer diameters for specific steel types and yield points.
Key Data from Tables: Tables list various dimensions, torque values, axial forces, and part numbers for different sizes of shrink discs and trantorques, including parameters like maximum torque (Mt), maximum axial force (Fa), and installation torque (MA).
