Industrial gearboxes

Inline Helical Gearboxes

Amiga Engineering™ Pty Ltd continue to manufacture Genat and Wood™ inline helical gearboxes in Australia, and from Australian-Made components. In short, Genant and Wood™ gearboxes continue to be one of the most high-quality, reliable gearboxes available. Many of the Genat and Wood™ gearboxes have seen 30 or more years of service…that’s right, you read it…30 years or more! Availability of spare parts is immediate.


Amiga Engineering™ Pty Lts is also the Australian agents of the high-quality, Italian-Made, Varmec and Tramec branded gearboxes. These items are more cost-effective than well-known brands, yet deliver at least the same service life of our Genat and Wood™ gearboxes.

Amiga Engineering™ provide the Varmec inline helical gearboxes in cast iron – for durability and longevity for your needs.

Why choose helical or inline helical gearboxes?

You will find that in applications requiring higher torque, a helical gearbox provides a better solution. Helical gears operate more smoothly and quietly due to the way the teeth interact. The teeth on a helical gear cut at an angle to the face of the gear. When two of the teeth start to engage, the contact is gradual – starting at one end of the tooth and maintaining contact as the gear rotates into full connection. Helical gears are more commonly used in transmission, this is because they can generate large amounts of thrust and use bearings to help support the thrust load.

VARMEC gear reducers and motor- reducers have been entirely designed using leading edge technical computer software.

Each single component has been designed and tested in consideration of the maximum loads applicable to the reducer in compliance with AGMA 2001-B88. Casings and flanges made from non varnished aluminium in sizes 141 to 162.

Casings and flanges of all other sizes are made from varnished, highly resistant cast iron. The rounded shape of the casings gives the gear reducers an optimum rigidity and solidity allowing for use in all possible assembly positions.

The manufacturing process of the various components is done by modern CNC machinery that gives maximum precision construction. All gears are made from hardened and tempered alloy steel with successive corrections to better the performance and reduce noise levels even whilst running with a load.

The input shaft is made from hardened and tempered alloy steel; the output shaft from high strength steel. Gear reducers are varnished with a thermosetting powder based on polyester resins modified with an epoxy resin: colour Burnt Blue RAL5010.

VARMEC gearboxes are available in 4 sizes (141-191/241-281-381) for the types with only one stage of reduction and in 8 sizes (162-200- 250-300-350-450-550-600) for the types with two and three stages of reduction.

Input power from 0,09 to 54 kW
Torque from 15 to 3000 Nm
Reduction from 1:1,2 to 1:317

Every gearbox can be supplied with IEC input flange (RCV) for IEC electric motors or in the solid input shaft (CV) version. Input flanges NEMA are also available. A wide variety of output shaft diameters are avilable for each size of gearbox.

Aluminium in line helical gears

Varmec presents its catalogue of the new sizes of helical gearboxes in aluminium RCV202 and RCV252. This new solution makes the product more competitive: it can now suit those applications which do not require the cast iron housing, which up to now was the only available on offer.

CV vs. RCV

Varmec Inline helical reducers have two options available for clients, we have the CV vs. RCV

CV = Reducer without input (motor end) flange

CV vs RCV single stage



RCV = Reducer with input (motor end) connection

Amiga Engineering Pty Ltd has all parts needed for either option, ready in Australia for all current customers and for new customers/clients.
