ML Clamping Sets Overview
ML Clamping Sets are designed for secure torque transmission between shafts and hubs, offering easy mounting and removal, backlash-free connections, and high fatigue strength. They are suitable for construction machinery and robotics but not for aircraft drive systems.

Features and Advantages

Easy mounting and removal with conventional tools.
Backlash-free and releasable connections.
High machining tolerances and self-centering elements.
Overload protection to prevent damage.
Economical and precise shaft/hub connections.

Calculation Instructions
For dimensioning shaft and hub connections, maximum loads must be calculated. The transmissible torque and axial forces depend on the tightening torque and cannot be transmitted simultaneously. Formulas and factors for calculating the hub and shaft dimensions are provided.

Hub Coefficient and Material Selection
The hub coefficient K is determined by the surface pressure and material yield point. Tables provide factors for different materials and pressures to ensure the hub's structural integrity.

Product Types and Specifications
The document lists various MLC clamping set types, each with specific torque and axial force capabilities, recommended fitting tolerances, and applications. Detailed specifications for each type are provided, including MLC 1000, 1010, 2000, and others.

Design Features
The clamping sets feature slotted and non-slotted designs, with self-centering capabilities for excellent concentricity. The designs facilitate easy assembly and disassembly, with some models requiring push-up screws for release. The document emphasizes the importance of maintaining specific tolerances for secure press fits.

Performance and Usage
The transmissible torque values are provided for different numbers of clamping sets used in succession. The document also explains how to calculate the resulting torque when axial forces are present, ensuring it does not exceed the transmissible torque. Recommendations for initial tensions and tightening torques for screws are included, based on DIN 912 standards.

Recommendations
The document advises on the appropriate shaft/hub fitting tolerances for different diameters and provides guidelines for selecting the number of screws based on the required clamping force. It also includes instructions for dimensioning the tension flange and selecting the diameter of the pitch circle for screws.

Procedures
Instructions for mounting and removal of clamping sets are provided. The document stresses the need for clean contact surfaces and the application of a thin oil film. It describes the process of tightening screws in a cross pattern and the importance of not aligning slots in the inner and outer rings. For removal, it advises loosening screws gradually and using ejector screws or gentle tapping if necessary.

Standards and Recommendations
The document recommends specific fits for shaft/hub bores based on ISO standards and provides guidelines for transmissible loads. It highlights the importance of material strength and surface roughness in ensuring effective power transmission.

Special Designs
Special versions of MLC clamping sets are available for unique applications, offering options like special materials, dimensions, and transmission torques. The document encourages consultation for custom solutions.

Product Overview
The document briefly mentions other products offered by the Walther Flender Group, including timing belts, shaft couplings, drive assemblies, conveyor rollers, and gears. It highlights the availability of custom solutions and the use of modern manufacturing techniques.

Key Data from Tables
The tables provide detailed measurements and specifications for various clamping set sizes, including shaft diameters, dimensions, screw types, torque, and axial force. They also include recommendations for transmissible loads based on shaft/hub fit and material properties.

Conclusion
The Walther Flender Group offers robust and adaptable clamping solutions with a focus on quality, innovation, and customer service. Their products are designed to meet the evolving needs of modern industries.

Walther Flender Group MLC Clamping sets Features and advantages ML clamping sets transmit torques from shafts and hubs simply and securely, because they create non-positive and backslash free connection which can be released at any time. Even for variation in stress or shock loadings, our clamping sets are distinguished by their good fail-safe behaviour and they can in fact be re-used or replaced by many times. Our adaptable installation-ready range of types is suitable for construction machinery and also for robots. ++ Easy mounting and removal Mounting and removal by tightening or loosening...

Walther Flender Group MLC Clamping sets Calculation instruction For dimensioning of a connection between the shaft and hub, the maximum occurring loads (rated value x load factor) have to be reliably determined and included in the calculation. The transmissible values listed in the table for Mt and FAX apply to the tightening torques MS and cannot be transmitted simultaneously. For simultaneous acting torque and axial load, the resulting value MR has to be calculated. This value cannot be greater than the transmissible torque Mt. Information on calculation for specific models is provided separately....

Walther Flender Group MLC Clamping sets Hub calculation The hub material is subjected to tensile stress by the pressure of the clamping set in the bore. The required outer hub diameter depends on the material, the installation position of the clamping set and the surface pressure in the hub bore. To keep the stress within the flexible range, the yield point Rp0,2 is the permissible material property value. The following table shows hub diameter factors based on the three parameters mentioned above. The hub factor X is determined based on the installation position. The calculated surface pressure...

Walther Flender Group MLC Clamping sets Description of types & tables MLC 1000 This very standard clamping set is suitable for average torques and requires precentring, the fit of which determines the concentricity. The slotted design of the double tapered rings enables relatively high mounting tolerance: for shafts between k11 and h11 and for hub bores between N11 and H11. The maximum shaft/ hub tolerance difference should be < IT9. We recommend h9/H9 for the shaft/hub fit. The large taper angles are not self-locking and facilitate the releasability of the connection. Normally, the conical pressure...

Walther Flender Group MLC Clamping sets MLC 1010 The three-part clamping set is an alternative to model 1000 with small outer diameters and likewise for average torques. The pre-centered fitting position facilitates assembly and produces very good concentricity. Due to the relatively small taper angle, the clamping connection must be released by push-up screws when dismantling. This is done by pulling the front tapered ring outward.

Walther Flender Group MLC Clamping sets Dimensioning of the tension flange The model 2000 clamping set can be used universally due to the compact design and the possibility of shaft- and hub-side clamping and multiple arrangement. The non-slotted clamping elements are clamped against each other in pairs as thin-walled inner and outer rings via tapered surfaces. The rings are deformed in the flexible area to produce a press fit between the shaft and the hub. The taper angle is not self-locking. After releasing the clamping screws, the rings are automatically unclamped. The diameter of pitch circle...

Walther Flender Group MLC Clamping sets MLC 3000 This clamping set is self-centring with excellent concentricity. The extremely small outer diameter is space-saving and suitable for small wheel diameters. The spacer ring between the outer flange and the hub maintains the fitting position in the axial direction to enable exact positioning without a shaft collar. The push-off threads in the outer flanges are used for dismantling. Recommended shaft/hub fitting tolerances
