BoWex® HEW Compact curved-tooth gear coupling

The curved-tooth gear coupling BoWex HEW Compact is a highly flexible shaft-to-shaft coupling particularly suitable for compensating for high displacements.

A compact design, axial plug-in and low restoring forces characterize this type. Typical applications of this gear coupling are applications with severe torsional vibrations such as screw compressors, piston compressors or transfer pumps.

For an optimum selection of the gear coupling various kinds of elastomer Shore hardness are available to adjust the torsional stiffness perfectly to the application.
Specifically when using drives with electric motors this highly flexible coupling proves its benefits.

In addition compensation of axial length is possible via the typical BoWex spline.

The polyamide material allows for maintenance-free permanent operation with very good coefficients of friction of the teeth.

Subject to the double-cardanic operating principle of the BoWex® gear couplings restoring forces can be ignored with angular and radial displacements and periodical fluctuations of angular velocity do not appear. 

BoWex® gear couplings can be assembled in vertical or horizontal design.

The smooth and hard surface (crystalline structure) along with the high thermal stability and resistance to lubricants, fuels, hydraulic liquids, dissolvents, etc. make polyamide an ideal material for components stressed by sliding, specifically for coupling manufacture.
