RfN 7015.1 for bending moments
Reduced contact pressure for thin-walled hubs
Transmits high combined forces and moments. Very good centring capability.
Precision locking assembly for transmitting high torques
Our RfN 7015.1 precision locking assembly is specially designed for reliable transmission of high torques and axial forces. At the same time, it meets special requirements concerning the radial run-out of the clamped parts and is also suitable for applications where bending moments occur.
One of the outstanding features of this locking assembly is that it reduces contact pressure on the shaft and hub. This not only ensures the dependable transmission of forces, but also helps to protect the components involved.
Precision and reliability are extremely important in belt drums and press drives – just two examples of applications where the RfN 7015.1 locking assembly truly shines.
Product features
- Locking assembly for transmitting torques, axial forces and high bending moments with reduced contact pressure when the clamped parts are subject to special radial run-out requirements.
- Special features – the long and flat angles of the cones allow the required loads to be transmitted with a single RfN 7015.1 locking assembly. During assembly, the locking assembly, shaft and hub all remain correctly positioned in relation to each other, ensuring additional safety compared to 3-piece versions. The shaft and hub are only compression-loaded.
- Bending moments and radial loads – combined loads can be transmitted.
- Excellent centring ability – thanks to the precentring web and
the relatively wide design.
Applications
- Belt drums
- Press drives
Locking assembly installation
The values for T, Fax, pW and pN apply to oil-lubricated, installed locking assemblies.
Surface finishes
For shaft and hub bore Ra ≤ 3.2 μm
Tolerances
We recommend the following installation tolerances
Shaft: h8; Hub: H8
Arrangement of several RfN 7015.1 locking assemblies
A maximum of 2 locking assemblies can be installed directly one after the other. In this case, the transmission values from the table need to be doubled.
Changing the screw tightening torques
It is possible to reduce the contact pressure and the transmission values by lowering the screw tightening torque. The permissible lower limit is calculated by multiplying the TA values by 0.5. There is a direct relationship between the values of T, TA , Fax, pW and pN.
