RfN 7015.0
Suitable for bending moments
5-piece precision locking assembly, self-centring. No axial displacement of the hub and shaft.
5-piece precision locking assembly, self-centring.
Our precision locking assembly is designed for reliable transmission of the highest possible torques and axial forces. At the same time, it meets stringent requirements concerning the radial run-out of the clamped parts. This locking assembly is also ideal for applications where bending moments occur.
The outstanding centring ability of this locking assembly ensures precise alignment and dependable force transmission. What’s more, it is capable of handling combined bending moments and radial loads.
Maximum precision and reliability are crucial in applications such as belt drums, crusher rotors and precision drives – just a few examples of where our precision locking assembly excels.
Product features
- Precision locking assembly for transmitting the highest possible torques or
axial forces when the clamped parts are subject to special radial run-out requirements,
and for applications involving bending moments. - Large transmissible peripheral forces – the long, flat angles of the cones enable the highest possible torques and axial forces to be transmitted with a single RfN 7015.0 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.
Example applications
- Belt drums
- Crusher rotors
- Precision 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 7015.0 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 0.8. There is a direct relationship between the values of T, TA , Fax, pW and pN.
