New range of heavy-duty industrial gear units.

Renold Gears has launched a new range of heavy-duty helical and bevel/helical industrial gear units with double, triple and quadruple reduction gear stages for high torque applications up to 162,000Nm. The new H-Series range has high-load carrying capacities, increased efficiency, quiet running and reliability. 

The units are manufactured with case hardened and profile ground gears with an involute thread profile to give maximum power transmission, smooth operation, long life, and maximum efficiency. They are available in 8 frame sizes, for either horizontal or vertical mounting, and can be custom designed specifically for customers’ applications. Modular design and construction offers many engineering and performance benefits including a high degree of interchangeability of parts and subassemblies. 

A variety of unit types is available for flexibility in design mounting and a wide range of ratios from 6:3:1 to 315:1 enables speed matching across most industrial applications. The range includes parallel shaft helical units and right angle bevel/helical units, with hollow and solid shaft variants. 

Design options include fan and water cooling to allow for greater torques to be transmitted at higher speeds, motorised and speed reducer versions, output shaft, single or double extension, or hollow output for direct shaft mounting. All units are Atex compliant and can be supplied against Group 2 or 3 for surface industries in designated hazardous locations, zones 1 and 2 for gases, vapours and mists, and zones 21 and 22 for dust.
