Economical connection of hubs and shafts, without the need for parallel keys
ExpaHub
Economical connection of hubs and shafts, without the need for parallel keys
Removable two-piece Hydraulic Nut
with saw-tooth profile for quick-clamp connection.
Optimum shaft and axle connection
even in extremely limited space. Maximum torque transfer even when direction is changed abruptly
Pressure distribution grooves
on tapered surface for easy installation and removal even after years of service – reusability guaranteed.
Inner tapered sleeve
of tough, high tensile strength steel for maximum transfer of force.
Outer sleeve of high tensile steel with tapered inner bore
is mounted without wear by widening with hydraulic pressure.
Advantages
- Lowering of costs, since the flange has not to be forged on shafts or axles, respectively lowering of material and chipping costs
- High torque transmission, completely free from backlash
- Separate, removable Hydraulic Nut – only one for a number of couplings
- Torsionally and flexurally rigid connection even with sudden changes in the rotational speed, torque, or direction of rotation
- ExpaHub can be removed simply and quickly even after years of use
- Reusability after removal – helps reduce costs
Versions
- Tapered Bolt and Conical Sleeve of high-strength quenched and tempered steel for maximum shear strength and axial load capacity
- Two ultra-high-strength Round Nuts
- Fine thread for maximum fatigue strength
- Pressure connection bore and pressure distribution grooves on the taper for easy removal of the Tapered Bolt
