Ringfeder RfN 7515 Locking Assembly

Characteristics

• Precision Locking Assembly for transmission of torques, axial forces and special optimised for the transmission of bending moments, with special requirements to the true running of the clamped pieces.
• Special features - Through the long and flat cones one Locking Assembly RfN 7515 can transmit torques and axial forces and bending loads. During mounting occurs a slight axial movement from Locking Assembly and hub.
• 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.
  
  

Example applications:

• belt drums
• gear wheels
  
  

Mounting of Locking Assembly

The values for T, F_ax, p_W and p_N apply to Locking Assemblies installed in oiled condition.

Surface finishes

For shafts and hub bores R_a ? 1,6 ?m

Tolerances

We recommend the following mounting tolerances

Shaft: h8; Hub: H8

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 T_A values of the above table by 0,8. There is an approximate linear relationship between T, T_A , F_ax, p_W and p_N.
