Keyless Locking Assembly RECCA06 – High Torque Solution


Keyless Locking Assembly RECCA06 Features

The Keyless locking assembly Recca 06 is similar to the Recca 04 product that it adds a distance ring to  prevent the axial movement of the hub during the process. Due to the increased friction between the element and the hub during the clamping process, the maximum torque is reduced, but the surface pressure is also reduced. This design can be mounted within the confines of the hub by providing a stepped hole to accommodate the flange.

What is a Recca Keyless Locking Assembly?

Recca Keyless Locking assemblies offer the latest in transmission connection technology.

Recca  shaft locking assemblies connect all types of drives to their respective shafts by means of frictional forces for torque and axial thrust load transmission. Precision tapered thrust cones within the clamping element create high pressure between the shaft and hub to securely hold pulleys, sprockets, gears, etc. The stresses on the hub and shaft are similar to a heavy pressure fit, but the actual stresses are easy to calculate, and the hub can always be easily removed without a damage to the shaft. All you need for assembly and disassembly is a torque wrench.

The shaft clamping element allows backlash-free precision torque transmission without the need for strict manufacturing tolerances of the mating parts. The simplified design results in reduced manufacturing costs and is easy to assemble and disassemble.
