Details:

Especially for the bending moment transmission designed 3 part Locking Assembly with reduced stresses in the Locking Assembly itself. Available in sizes 60 to 640 mm.

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, Fax, pW and pN apply to Locking Assemblies installed in oiled condition.

Surface finishes

For shafts and hub bores Ra ? 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 TA values of the above table by 0,8. There is an approximate linear relationship between T, TA , Fax, pW and pN.
