Description

Characteristics of SCWO Series Shaft-mounted Arc Cylindrical worm drive gearbox

SCWO Series Shaft-mounted Arc Cylindrical worm drive gearbox (standard by JB/T6387 – 1992) is directly assembled on the working machine spindle, including SCWU, SCWS, SCWO three series.

  • Worm drive gearbox and worm gears are precisely forged by high rigidity steel and high-quality alloy steel respectively, and they are hobbed and ground which brings lower noise and temperature rising.
  • Gears and shafts are carburizing hardened and quenched to HRC 55-62.
    Gears and shafts used are the top brands in the domestic market. And we can import world-famous brands, like SKF to custom design the products to meet our customer’s special requirements.
  • Elegant appearance.
  • Long service life.
  • ISO 9001 and CE were quality approved.

Working conditions:
the speed of the worm shaft of the worm gear gearbox does not exceed 1500 r/min; the working environment temperature is – 40~40 °C. When the working environment temperature is lower than 0 °C, the lubricating oil must be heated above 0 °C before starting; the worm gear gearbox can be positive Reverse operation.
