Shaft Clamping Elements provide the latest technology in drive connection.
Cross Shaft Clamping Elements, by means of frictional forces, provide connection
of all types of transmission equipment to their respective shafts, enabling
transmission of both torque and axial thrust loads. Precision tapered thrust
cones within the clamping elements create high pressure between shaft and
hub to securely fasten pulleys, sprockets, gears etc. Stresses in both hub
and shaft are similar to heavy press fits, however, the actual stresses
are easy to calculate; and the hub can always be easily dismantled without
damage to it or the shaft; only a torque wrench being required for both
assembly and disassembly.
Precision transmission of torque with no backlash is obtained with shaft
clamping elements, without the need of tight manufacturing tolerances of
mating components. Simplified designs can enable manufacturing cost reductions,
coupled with easy assembly and disassembly.
Cross Shaft Clamping Elements provide an alternative method of connecting
hubs to shafts to:-
Hydraulic Clamping Systems
Fine-bored Hubs, with Precision keyways and Locking Setscrews
Heavy Press Fits
shaft clamping elements provide maximum torque transmission from a single
unit, but, due to their large clamping surfaces clamping pressures are kept
to reasonable levels. The design enables automatic centring between shaft
and hub, and axial positioning of the hub does not change during clamping.
Suitable for applications with high bending loads.
shaft clamping elements are very compact units capable of transmitting medium
torques. Their design ensures good concentricity between hubs and shafts,
without any other means of location. A slight axial movement between hub
and shaft occurs during clamping. These units can be installed totally within
the hub providing optimum safety, and minimal axial length.
for use with standardised ranges of pulleys, sprockets, and gears, the shaft
clamping elements can accommodate a large range of shaft diameters with
a hub of constant bore diameter. On clamping precise axial and radial positioning
is provided, combined with medium torque transmission capability.
