PRODUCT ANNOUNCEMENT: BACKLASH FREE DISC PACK COUPLING FOR ALTERNATING LOADS
The new disc pack coupling with dual conical clamping hubs (model LP3) is one of a new series of precision disc couplings from R+W.
The model provides torsionally rigid transmission while compensating for shaft misalignment. The combination of high strength bolts and frictional clamping bushings enables backlash free torque transmission through the disc pack set, and the shaft clamping system locks down without allowing any relative movement between the hub and the shaft. As a result the LP3 is ideal for changing and reversing loads. The self centering characteristic of the conical clamping bushings also allows the coupling to run smoothly at high speeds.
Beyond the LP3 there are 4 variations of the coupling in this new series, mostly in double flex configurations in order to compensate for lateral misalignment. These other versions are available with clamping hubs and keyway connections, as well as a special version for API 610 pumping applications.
The various models are available in different sizes corresponding to torque ratings ranging from 350 to 20,000 Nm.
