Miniature Gearboxes For High Power Density and/or Excellent Reliability

PowerGear Miniature bevel gearboxes are compact yet capable of transferring considerable levels of torque, at high speed and with high efficiency. They are robust and designed to be maintenance free, so are ideal for applications that require high power density and/or excellent reliability. They are also lightweight, so suited to use in mobile applications.


The PowerGear range of miniature gearboxes is manufactured by MS-Graessner, which has been cutting gears and leading related design and development ideas for over sixty years. They are available in the UK through Drive Lines Technologies Ltd.

Ian Carr, Managing Director of Drive Lines is enthusiastic about them, saying: “Dimensions, weight, and precision – the PowerGear Miniature sets new standards. Throughout the range, the compact design gives an incredibly small installation size and the aluminium housings make them ultra lightweight. Their performance resets user expectations in terms of both power and precision.

“The unique design of PowerGear Miniature is opening up a vast range of new applications. We expect them to become popular in areas such as medical equipment, food processing, packaging and specialist automation. ”

Design features that set PowerGear Miniature apart from other gearboxes include a case-hardened bevel gear tooth system, a friction locked shaft and bevel gear fit and an extremely lightweight aluminium housing. This ensures low backlash and high transmission accuracy alongside an energy efficiency of 98%. Lubrication is based on long life maintenance free synthetic oil.

PowerGear Miniature is available in three sizes. The smallest, P27 has a footprint of 27 square millimetres; it is offered with two ratio options, 1:1 and 1.5:1, with nominal output torque being 3.5Nm. The larger P33 and the P45 are both available with five ratio options, 1:1, 1.5:1, 2:1, 3:1 and 4:1 and they have nominal output torques of 5Nm and 16Nm respectively. Input speed for all of them is up to 7500rpm.

A Gleason gear tooth profile is used throughout the range. This optimises the contact pattern throughout the tooth to tooth engagement cycle so that the load is uniformly spread across the tooth, enabling the high speeds and high torque performance.

Carr again: “The Powergear Miniatures are offered in a standard range but are also suitable for customisation so that they perfectly match the needs of individual applications.”
