Modular, reliable gear units designed for conveying and similar uses

With applications in brown and hard coal mines, copper and sulphur mines and other general purposes, MAAG® GEAR KA / KB gear units deliver high-performance torque transmission for the mining industry. Along with the MAAG® GEAR KA / KB gear boxes, the MAAG® GEAR Temperex series offers a variety of types, sizes and ratios – sure to meet your precise industrial gear requirements in the cement and mining industries.

Optimal belt conveyor drives

Designed to transmit torque from your electric drive motor to the conveyor shaft, the MAAG® GEAR KA / KB gear units are most often used for belt conveying in the cement and mining industries. For both the KA and KB gear units, the input gear stage is built as bevel gear, followed by a single spur gear reducer stage with the KA and a double reducer stage with the KB.

Adaptivity through uniformity

In order to accommodate the widest possible range of requirements, MAAG® GEAR Temperex gear units are standardised and modular – delivering the perfect fit for your gearbox needs in the mining and cement industries. The dimensions, ratios and power output of the Temperex gear unit are based on the R20 geometric progression series and in accordance with ISO 3/UNI 2016/DIN 323 standards.

With its modular design, the MAAG® GEAR Temperex gear unit accommodates your needs rationally and economically in nearly every industrial application.

Built to last

The high strength and wear resistance of the KA / KB gear units and the full Temperex range come from smart design, well-manufactured components and top-notch materials. The KA / KB gear units use cyclo-palloid toothing for the bevel stage, with gear wheels made of an alloy, case-hardened steel. The roller bearings used by the KA / KB gear units depend on the load type transmitted and have a long operating life.

The KA / KB gear units come standard with a splash-gravity lubrication system and a condition monitoring system, both of which can be upgraded. The standard versions of the MAAG® GEAR KA / KB gear units function at peak performance in environmental temperatures ranging from -30°C to 40°C – and accessories allow belt conveying systems to be driven in even more extreme environments.

The gears in the MAAG® GEAR Temperex range are made of chrome-nickel molybdenum steel and case-hardened and ground on precision tool machines. The modified tooth profiles of the cylindrical helical gears used in Temperex gear units limit scuffing or scoring – and provide better load distribution.

The light, compact construction of the KA / KB gear units and the Temperex range does not mean lightweight performance; the gears are designed and built to provide you with smooth, efficient operation for years.

Out-of-the-box performance

The gear units undergo a trial run in the manufacturer’s factory test station before shipment, so they are operationally fit and ready for use. The reducers in the Temperex series are also delivered ready for operation, after having undergone strict test bench inspections before being sent to your plant.

Design and manufacturing

The gear units are developed using state-of-the-art design processes that apply the newest calculation methods through advanced computer techniques. Engineers and machine operators use engineering programs and computer software to design and precisely manufacture durable components.

Recent developments in heat treatment and tooth machining produce long-lasting, well-fitting components that contribute to the reliability of the gear units. Precise machines and a strict control process ensure high-quality rotors and casings. Advanced manufacturing processes ensure the design assumptions are met, giving gear units with quiet operation and high efficiency.
