Specifications
BoWex couplings are suitable to compensate for axial, radial and angular shaft misalignment. Original from KTR, Germany.
BoWex Curved-Tooth Gear Couplings from KTR are flexible shaft connections for a positive torque transmission and specifically suitable to compensate foraxial, radial and angular shaft misalignment.
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.
Design
The material combination of steel hubs and polyamide sleeves allows formaintenance-free continuous operationwith very low friction on the teeth.
Due to thedouble cardanic operationof 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
The standardpolyamidematerial is characterized by the following positive features:
- high mechanical consistency
- high stiffness
- high thermal stability (+100 deg C)
- good viscocity even in case of low temperatures
- favourable slide-friction behaviour
- very good electrical insulating property
- good resistance to chemicals
- good dimensional accuracy
The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents, etc., makepolyamidean ideal material for components stressed by sliding, particularly for the coupling production.
While any metallic materials tend to corrode in case of dry running, slide combinations withpolyamideand steel are operativewithout any lubrication and maintenance.
