At Aimex 2007, leading drives solution group, SEW-Eurodrive will introduce the Australian mining industry to the company’s sophisticated new industrial gear solution--the SEW-Eurodrive X series.
Comprising 23 different models--each with a different torque rating--the complete X series boasts the finest torque-graduation on the market, providing Australian mining/mineral processing operations with unrivalled gear unit choice and flexibility.
The first-phase release of SEW-Eurodrive’s X series sees eight models made available, with larger sizes to follow in 2008. This initial X series release is available now and offered in a range of mounting arrangements and configuration options.
The ‘big brother’ of SEW-Eurodrive’s MC Compact industrial gear units, the X series features helical and helical-bevel gear technologies that deliver torques from 58,000 to 175,000Nm.
This makes it ideal for mining applications, such as conveyors and stacker/reclaimer bucket loaders, as well as apron feeders and ship loaders.
According to SEW-Eurodrive national product manager industrial gear units, Ian Tribe, the X series’ comprehensive torque-rating options simplify the task of matching the industrial gear unit to the drive application.
“The Australian mining operations are now able to select a short delivery industrial gear unit that is effectively tailored to their drive application,” he said.
“With competing gear unit manufacturers offering fewer gear unit models and torque ratings, users often have no choice but to select an oversized unit to accommodate their drive application,” said Tribe.
“An oversized gear unit generally means an oversized unit weight, installation space and capital expenditure. “The X series allows users to obtain the ‘best fit’ gear unit solution and avoid unnecessary up-sizing, saving time, cost and space.
All members of the new SEW-Eurodrive X series feature a revolutionary housing that allows the gear units to be inverted.
“The X series can be ‘flipped over’ to transform a left-handed unit into a right-handed one,” said Tribe. “This means mine-sites can reduce the number of complete gear unit spares kept on site, and avoid time-consuming off-site re-builds, which are often required to achieve the same result.”
The entire X series is 100 % SEW-Eurodrive-designed with all parts manufactured in-house.
It boasts a modular design and is assembled from a range of standard components.
Further flexibility is achieved via the X series’ ingenious internal component design--only a handful of standard multifunctional internal components, are required to build all models.
The modularity of the X series allows shortened delivery times, as units are assembled from stock parts. This component commonality allows users with multiple X series gear units to minimise spare parts inventory.
All X series internal gearing, both helical and bevel, feature a ground finish to ISO quality level 6.
The ground finish process produces components with advanced fatigue strength properties and heightened resistance against breakage. It also allows the X series units to run quiet--a real benefit on noisy mine sites.
An optional advanced fan design allows the X series to maximise its overall operating efficiency. Typical fan covers employed by other gear unit assemblies usually sit flush against the input coupling, and risk obstructing intake air flow.
The X series’ fan features a conical-shaped fan cover with the air intake grill positioned on the side faces to maximise air flow.
“The introduction of the X series builds on our already extensive range of industrial gear unit solutions,” said Tribe “SEW-Eurodrive prides itself in being able to provide the Australian mining/minerals processing sector with the country’s most comprehensive selection of industrial gear units.”
