Gear couplings

From the large success obtained with our cardan transmissions is the new range of gear couplings EPR XG series.
The joints of the XG series are manufactured and available hardened steel AISI1045, AISI4140 or stainless steel AISI630. Class 12.9 bolts, stainless steel grease caps and o-rings in rubber NBR or Viton.
The operating principle of the gear couplings synthetically illustrated in the figure beside relies on engagement of the external teeth of the hub with the internal toothing of the sleeve, or bell, which allows the transmission of torque between the flanges. The relative misalignment is compensated by axial sliding of the internal gear teeth on the external gear teeth.
Using the rounded gear, our joints ensure optimal connections and torsionally rigid, one of the most different devices, even with moderate misalignment, axial and radial.
Maximum allowed misalignment of the joints EPR:
- Standard series: 0°10’
- With heat treatment: 0°15’
The rounded gear of gear couplings EPR XG series, is designed to ensure conditions of misalignment of more extended surfaces of contact.
The offset of the profile used determines the increase of the thickness of the tooth and therefore the resistance of the own gear.
