Extended 3-piece version, self-centring. Suitable for bending moments and radial loads
This 3-piece locking assembly, specifically designed for transmitting bending moments, features reduced stresses within the assembly. As a result, the required loads can be transmitted safely and reliably using a single locking assembly of type RfN 7515. During assembly, the locking assembly and hub undergo slight axial displacement.
A special feature of this locking assembly is its ability to combine both bending moments and radial loads during their transmission. For specific applications and loads, we recommend contacting our specialists to identify the optimum solution.
The wide design of the locking assembly ensures excellent centring ability, which is advantageous in various applications. Some example applications for this locking assembly are belt drums and press drives.
Product features
- Precision locking assembly for transmitting torques and axial forces, specially optimised for bending moments, and designed for use when the clamped parts are subject to special radial run-out requirements.
- Special features – the long and flat cones allow the required loads to be transmitted with a single RfN 7515 locking assembly. During assembly, the locking assembly and hub undergo slight axial displacement.
- Bending moments and radial loads – combined loads can be transmitted.
- Excellent centring ability – thanks to the relatively wide design.
Example 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 ≤ 1.6 μm
Tolerances
We recommend the following installation tolerances
Shaft: h8; Hub: H8
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.
