Disc Pack Couplings with Integrated Coolant Tube
R+W has recently expanded its line of LP disc pack couplings. In addition to standard designs, R+W can now supply a version with an integrated coolant tube. This offers valuable advantages to manufacturers of machine tools with long spindle drives.
This specially designed double disc spindle coupling can transport coolant directly to the cutting head over long distances using an integrated inner tube and special adaptation interfaces on each end. Since these couplings are often used in highly dynamic, high speed applications, lightweight CFRP or aluminum spacer tubes are typically used. Highly symmetric conical clamping ring hubs and fine balancing helps to guarantee smooth running operation. Misalignment between the drive and driven shafts is compensated for by the torisonally rigid disc packs. This robust, high performance line of couplings provides users with a simplified spindle setup, reduced assembly times, faster operating speeds, and longer tool life.
