BoWex Curved-tooth gear couplings

BoWex Curved-tooth gear couplings from HAW are flexible shaft connections for a positive torque transmission. According to the well-known effect of curved-tooth gear couplings, any edge pressure in the spline in case of angular and radial displacements is avoided so that BoWex couplings are almost free from wear.

On couplings with spur toothing, high edge pressure along with considerable wear arises at the contact surfaces in case of misalignment. The curved teeth of the BoWex hub avoid any edge pressure on the coupling in case of angular and radial misalignment.

The material combination of steel husband polyamide sleeves allows for maintenance-free continuous operation with very low friction on the teeth. Due to the double cardanic operation of BoWex couplings, restoring forces may be neglected in case of angular and radial displacements and periodic fluctuations in angular velocity do not arise.

BoWex couplings can be assembled both vertically or horizontally with no need for any special assembly tools.
