Mid Worm Gear

Series AM

  • Robust design
  • High torque capacity
  • ATEX compliant

Description

Our range of Series AM worm gear units are based on a single universal case for each size, giving a high degree of common parts and interchange ability.

Under-driven, over-driven and vertical types provide a choice of shaft arrangements in meeting the requirements of a wide variety of applications in the medium power range up to 75 kW.

All units are designed with hollow bore output, while a plug in output shaft can be fitted allowing the installed side of the shaft to be changed without dismantling the unit. Series A Mid Range gives a choice of 12 standard ratios from 5/1 to 70/1 and important features include high efficiencies and load carrying capacities combined with long life and reliability in service.

Double Reduction Units (worm/worm)

These units consist of a standard single reduction unit with a smaller shaft mounted unit fitted to the input shaft. The three smallest sizes are fitted with shaft mounted Series A Junior units whilst the size 2002 is fitted with a size 1002 (C07 when motorised). The range extends the ratios available up to the maximum of 4200/1 making them ideal for fitting to slow moving machinery.

As with the single reduction units they are available in under-driven, overdriven and vertical types, foot mounting and shaft mounting.

Heavy Duty Mixer Units

Based on the standard Series A Mid Range the Heavy Duty Mixer Unit incorporates an extended bearing housing to accommodate a larger bottom bearing and increased shaft size, thereby enhancing the units capacity to absorb the high bending loads imposed during mixer applications.

These units can be ordered with a dry-well option to minimise the risk of output shaft leakage.
