2. Characteristics of KTR Gear Couplings BoWex I
– Manufacturer brand: KTR Germany.
– Consists of two steel gears combined with an outer plastic ring.
– Three-part design, made of nylon.
– Maintenance-free due to the combination of nylon materials.
– Low net weight, low moment of inertia.
– Operating temperature ranges from -25°C to +100°C.
– Shaft bore tolerance: +0.05 / -0.1.
– Stainless steel screws (V4A) as standard.
– The KTR Bowex I plastic outer sleeve coupling features a smooth and rigid surface along with high thermal stability and resistance to lubricants, fuels, hydraulic fluids, and solvents, making polyamide an ideal material for load-bearing components subject to sliding, particularly for coupling production. Polyamide material allows for permanent operation without maintenance with a very good tooth friction coefficient.
– Following the dual-action principle of the coupling, the restoring force can be disregarded with angular and radial displacements, and there are no cyclic oscillations of angular velocity. The Bowex I can be assembled vertically or horizontally.
