RFK … TBO series

RFK … TBO series

Product catalog summary

Overview: The document provides technical specifications and guidelines for the Tru-Line Flange-Couplings RFK … TBO, which feature a backlash-free cone clamping connection. These couplings are designed for applications requiring simultaneous transmission of torque, axial force, and bending moments, such as drive units and conveyor drives in mining.

Features:

Compact design with minimal axial space required for installation.
Quick disassembly to reduce downtime.
Large allowable shaft tolerance of h8, eliminating the need for keyways and preventing fretting corrosion.

Performance Considerations:

The maximum transmissible torque is reduced when axial forces and/or bending moments are present.
RINGSPANN provides selection calculations based on industry knowledge and safety factors to prevent fretting corrosion.

Technical Specifications:

Tolerances: Shaft diameters dF or dM should adhere to h8 tolerance.
Surface Finish: Average surface finish at contact surfaces should be Rz = 10 … 25 µm.
Materials: Suitable shaft materials are recommended using DIN 743 standards.

Ordering Information:

Coupling halves and fasteners can be ordered separately, with the indication of the coupling half corresponding to the size of the smaller coupling half.
Order example: RFK 0050 TBO-STA-FSC025-MSC025.

Mounting Instructions: Installation and operating instructions are available upon request. Paired coupling halves of the same color can be interchanged due to matching flange patterns, with the maximum torques of the smaller coupling half applying.

Data Summary: The document includes a detailed table listing sizes, transmissible torques, inertia moments, dimensions, and weights for various coupling sizes, along with the required tightening torques for connection and clamping screws.

Tru-Line Flange-Couplings RFK … TBO backlash free cone clamping connection Features • Compact design • Small axial space required for installation • Quick disassembly for minimal downtime • Large allowable shaft tolerance of h8 • Shafts are not weakened by keyways • No fretting corrosion like with keyway connections • Typical applications: Drive units and conveyor drives e.g. in mining Coupling flange with hub type MSC Coupling flange with hub type FSC Order example Coupling design Coupling size of smaller coupling half 0050 Type Hub A, type: • Flange with Female Pilot • Flange with Male Pilot Cone clamping element Transmissible torques Simultaneous transmission of torque, axial force and bending The transmissible torques listed on the follomoment wing page are subject to the listed tolerances, surface finishes and material requirements. Please contact RINGSPANN in case of devia tions. Tolerances • h8 for shaft diameters dF or dM Surfaces Average surface finish at the contact surfaces of the shafts Rz = 10 … 25 µm. Materials RINGSPANN is able to recommend suitable shaft materials using DIN 743 (12/2012 edition) taking the surface pressures for the Tru-Line Flange-Couplings RFK … TBO into account. Where there are combinations of axial forces and/or bending moments in the application in addition to the torque TN, the max. transmis sible torque will be r educed as compared to the values for TK max shown in the tables. RINGSPANN will select the proper coupling for each application based upon the allowed transmissible torque under existing bending moment conditions. Our selection calculations are in accordance with the latest scientific know-ledge and experience in the industry and will include the proper safety factor to prevent fretting corrosion. Please contact RINGSPANN.
