The new Series G helical parallel shaft and bevel helical right angle drive gear units have introduced to meet the requirements of today's demanding applications in the medium and heavy duty sector of the power transmission market. Innovative modular construction using power gear design technology has minimised manufactured part count to maximise availability of product.Gear tooth geometry design combines maximum efficiency with high load carrying capacity and minimal noise generation. Serviceability of the product was key in the design of the Series G range, allowing easy maintenance for long life and reliability which are synonymous with the David Brown name. Advanced Features :Horizontal split case for ease of maintenance. Case hardened and ground helical gears, and hard finished spiral bevel gears have optimised gear geometry to maximise strength and efficiency driven fans, and cooling coils. Patented end cover design to improve bearing lubrication and increase thermal capacity. Modular construction minimise the number of components, allowing maximum availability. Large diameter output shaft and output bearing to maximise overhung load capacity. Gear case design using finite element analysis to give high strength to weight ratio. Vertical and shaft mounted versions available as standard.
