Details
For superb centering and high torque transmission, this dual tapered device reflects the best in RINGFEDER® engineering expertise. This style is in two types, 7015.0 for general engineering applications and 7015.1 for conveyor pulley applications. Available in sizes 100 to 800 mm.
Characteristics
- Precision Locking Assembly for the transmission of maximum torques and axial forces with special demands on the concentricity of the parts of the clamped, as well as for applications subjected to bending moments.
- Large transmittable peripheral forces – due to the long, flat cones it is possible to transmit maximum torques and axial forces with one RfN 7015.0 Locking Assembly. During installation the Locking Assembly, shaft and hub remain in position to one another. Compared to 3-part versions, 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 7015.0 Locking Assembly has excellent centering ability.
Example applications:
- belt drums
- crusher rotors
- precision drives
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 ?m
Tolerances
We recommend the following mounting tolerances
Shaft: h8; Hub: H8
Arrangement of several Locking Assemblies RfN 7015.0
Max. two RfN 7015 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.
