Shaft Hub Locking Device RECCA 16 is consisted with three parts including inner ring, out ring and thrust ring. These locking device can provide medium to high torque and has features of rapid maintenance and assembly. Recca shaft hub locking devices are manufactured from carbon and heat treated alloy steels. In orderto improve corrosion resistance, all units are available in different grades of stainless steel (reduction of performances approx. 50%), as well as supplied with different surface coatings like zinc plating, nickel plating and phosphate treatment according to customer’s special request.

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.
