WORM GEAR REDUCERS

USER BENEFITS

Worm gear reducers and gear motors of A04 series are characterized with high efficiency, running precision, regular motion and noiselessness, constant performance, life and reliability, strength and overload withstanding and suitability for heaviest applications, wide size and ratio range, and excellent service.

  • Universal mounting having feet integral with casing on 3 faces (sizes 32 .. 81) or on 2 faces (sizes 100 … 250) and B14 flange on 2 faces. Design and strength of the casing permit interesting shaft mounting solutions
  • Thickened size and performance gradation
  • High, reliable and tested performances (Ni bronze); optimization of worm gear pair performances (ZI involute profile and adequately conjugate worm wheel profile)
  • Compactness, standardized dimensions and compliance with standards
  • Motor standardized to IEC
  • Rigid and precise cast iron monolithic casing
  • Generous internal space between train of gears and casing allowing for:
  • High oil capacity
  • Lower oil pollution
  • Greater duration of worm wheel and worm bearings
  • Lower running temperature
  • Possibility of fitting particularly powerful motors and transmitting high nominal and maximum torques
  • Improved and upgraded modular construction both for component parts and assembled product which ensures manufacturing and product management flexibility
  • High manufacturing quality standard
  • Possibility of obtaining multiple drives and at synchronous speed
  • Wide design and accessory availability: shaft-mounting arrangements, mixed keying systems with key and locking elements (rings for sizes 32 … 50, bush for sizes 63 … 250), square flanges for servomotors and hub clamp, reduced backlash, etc.
  • Reduced maintenance costs
