David Brown Engineering has extended its successful Series G range of medium/heavy duty helical gearboxes to increase the maximum output torque available by over 50%.
David Brown Engineering has extended its successful Series G range of medium/heavy duty helical gearboxes to increase the maximum output torque available by over 50%.
The company now offers Series G gearboxes in seven sizes from 11,000 to 130,000Nm output torque, with a ratio coverage of 6:3:1 to 315:1.
Designed to meet the requirements of applications including bulk handling, mixing, water treatment, cooling towers and conveyor drives, Series G units can be specified in parallel shaft helical and right angle shaft bevel/helical units in double, triple, and quadruple reduction gear stages.
Modular design and construction, a high degree of interchangeability of parts and subassemblies, and a universally machined, horizontally split casing has created a family of speed reducing gear units that can be quickly manufactured and is simple to maintain with obvious delivery and cost benefits for customers.
The innovative modular construction of the inherently reliable Series G units minimises part count to maximise availability of product.
Less than 160 major components meet 10,000 drive solutions.
In many cases units can be ordered and delivered within days compared to a typical schedule of up to 6 weeks for a comparable competitor unit.
This not only produces a radical reduction in potential down-time of vital plant, but also enables end users to reduce stock levels.
Strength and efficiency are maximised, while noise and vibration are kept to a minimum by case hardened and ground helical gears, and hard finished spiral bevel gears.
For extended, efficient life, oil is kept where it belongs by the patented end cover, which improves bearing lubrication and allows a 30% improvement in thermal capacity compared with competitor products.
The new generation Series G units also offer larger diameter output shafts for greater load capacity which is particularly appropriate for use on stirrers and mixers, while the motor adapter enables the configuration of a vertically down motor on a helical gearbox with a vertical down output shaft.
