Product Characteristics

  • Locking Assembly for transmission of torques, axial forces and high bending moments at reduced contact pressures, with special requirements to the true running of the clamped pieces.
  • Special features - With the long and flat angle of the cones, the required loads can be transferred with one Locking Assembly RfN 7015.1. During mounting Locking Assembly, shaft and hub remain to each other in position. Compared to three-part construction types, thus an additional safety is provided. Shaft and hub are only compression loaded.
  • Bending moment and radial loads – combined loads can be transmitted (Please contact our technical department for assistance).
  • Excellent centering ability – with a relatively wide design and the precentering web the RfN 7015.1 Locking Assembly has excellent centering ability.

Example applications:

  • belt drums
  • gear wheels

Mounting of Locking Assembly

The values for T, Fax, pW and pN apply to Locking Assemblies installed in oiled condition.

Surface finishes

For shafts and hub bores Ra ≤ 3,2 μm

Tolerances

We recommend the following mounting tolerances

Shaft: h8; Hub: H8

Arrangement of several Locking Assemblies RfN 7015.0

Max. two RfN 7015.1 Locking Assemblies can be used in series, the transmissible torques and axial forces are added.

Change of screw tightening torques

A reduction of the contact pressures and the transmission values by reducing the tightening torque of the screws is possible. the admissible lower limit results from the multiplication of the TA values of the above table by 0,8. There is an approximate linear relationship between T, TA , Fax, pW and pN.
