R+W - BELLOWS COUPLING BK6

Description

BACKLAY-FREE, TORSIONALLY RIGID AND ULTRA-PRECISE: METAL BELLOWS COUPLINGS FROM R+W

High-precision metal bellows couplings are used in all applications that require precise positioning: medical technologies, test benches, wind turbines or ultra-dynamic servo axes in machine tools, woodworking machines, manufacturing machines. packaging, etc. As a leading supplier, R+W strives to continually expand its range of metal bellows couplings for various applications in the most diverse sizes and designs.

MODE OF OPERATION: METAL BELLOWS COUPLINGS

Metal bellows couplings are particularly suitable for direct drives. The typical metal bellows is the key element of this coupling. It compensates for axial and angular misalignments for low restoring forces. The backlash-free, torsionally rigid metal bellows couplings ensure precise positioning of the drive unit and can be used in ultra-dynamic applications up to over 10,000 rpm on a finely balanced model.

Technical details

  • Structure :
    • 1 side with conical clamping hub with 6 ISO 4762 screws and 3 compression screws
    • 1 side with conical clamping hub with backlash-free conical plug connection and 3 compression threads
  • Temperature range: -30 to +120°C
  • Backlash: Absolutely backlash-free thanks to tight connection by force connection and axial pretensioning of the tapered plug segments.
  • Lifespan: metal bellows couplings are very durable and maintenance-free if the technical instructions are followed.
  • Tolerance clearance: of the shaft-hub connection 0.01 - 0.05 mm
  • Material :
    • Highly elastic stainless steel bellows
    • Tapered clamping hubs and bellows side tapered segment
    • Conical steel segment on hub side
    • Glass fiber reinforced plastic sprayed on steel hub
