R+W couplings have heavy-duty torque ratings
A
R+W Coupling Technology product story
Edited by the Engineeringtalk editorial team
Nov 5, 2009
R+W has introduced BK3 couplings with heavy-duty torque ratings and high-strength conical clamping hubs for high-torque servo gearboxes.
Manufactured with double-walled, stainless-steel bellows to absorb parallel, angular- and axial-shaft misalignment, the BK3 has a high torsional stiffness to complement its low moment of inertia - allowing it to handle rapidly indexing and reversing servo applications.
The couplings are manufactured with a tapered conical clamping element, which results in the highest shaft clamping forces, without keys, compared to any other hub design.
The BK3 coupling also incorporates disassembly screws to aid the mechanic in tight spaces.
The clamping sleeves are custom bored on each side for shaft diameters from 10 to 80mm (0.39 to 3.13in).
Sizes are available for torque capacities ranging from 15 to 10,000Nm.
