The RECCA17 A shaft locking assembly consists of a conical inner ring with a clamping bolt and an outer ring. The outer ring is tightened against the inner ring by tightening the clamping bolt. The resulting radial force depends on the fit of the clamping bolt and the taper angle to the clearance and taper surface.
Aligning the hub to the center of the shaft
Due to its size, this clamping element is ideal for short-cycle installation.
Easy mounting by means of clamping nuts
Designed for shafts from 15mm to 70mm in diameter.

Transferred drive torque and axial thrust load: -.
The maximum effective torque Te generated by the maximum driving torque Tm and the maximum axial thrust Ft must always be less than the torque Mt shown in the table for cone clamping elements selection.
The maximum drive torque Tm must take into consideration any shock loads, as well as the maximum drive starting torque. If the maximum torque is not known, the rated drive torque Td can be estimated from the service factor in the following table, which is derived from the motor power P and the Shaft speed N r.p.m.
Drive Torque Td = NM Where P=Power KW
Max. Drive Torque Tm= SF x Td d= Shaft Diameter mm
Maximum effective torque = NM Ft = Max. Axial Load N
d = Shaft Diameter mm
For correct selection for Shaft Hub Locking Devices
Torque Capacity M > Te(or Tm): and Axial Force Capacity F > Ft
Tilting or Bending Loads:-
Always endeavour to design location of shaft hub clamping element directly beneath line of driving force on hub, ie chain, V belt etc. If overhang of load or force occurs the torque capacity of the clamping element can be reduced.Under no circumstances should the resultant couple force on the clamping element exceed 0.25M.
