Helical geared motors will be the most conventional and cost-effective solution for most drive applications. Helical gear models are coaxial, where the gear unit output shaft is based on the motor shaft. A solid shaft is generally used as result shaft. Additional parts – e.g. gear wheels or chain tires – to transfer the push to the driven load are as a result required. Solutions making use of helical geared motors are capable of an extremely variable speed range.
SIMOGEAR helical geared motors are available for the energy range up to 20 HP (15 kW) and rated gear unit torques up to 5,900 ft-lb (8,000 Nm).

Helical Geared Motors for an array of applications
Motors with a helical gear unit from Ever-Power have a high power density and a huge number of options. The gear units are produced in three series and several sizes for a wide variety of applications.
Ever-Power Helical Gear Systems impress with exceptional features:
Powerful
Our helical gear systems give a maximum torque of 26,000 Nm (since an Industrial gear unit up to 250.000 Nm).
Efficient
High efficiency increases the productivity of the application.
Hygienic
Ever-Power Helical Gear Systems have wash-down capability because of their smooth surfaces.
Robust
If required, we can treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Protection, which also withstands aggressive cleaning agents.
Always the right option: Our Helical Geared Motors
No two applications are the same. Due to this, Ever-Power items three different drive solutions with helical gear units. All variants are available as flange or foot/flange mounted versions.
The all-rounder
Regular Helical Geared Motors have an array of uses and offer verified quality. This kind of geared engine is offered from Ever-Power in six sizes, in two or three stage versions with torque ranges from 50 to 700 Nm. We produce the gear wheels for helical gear units from highly wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a compact design, with an exceptionally robust grey cast iron casing. They include especially efficient motors to be able to operate as effectively as possible, even at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down able helical geared motors
With the Ever-Power series we positioned a high priority on a smooth, simple to clean surface. This feature is especially important for users in hygienically essential sectors like the food or pharmaceutical industries.
Depending on the size of the apparatus unit, we produce Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron casing. In this way you obtain optimum efficiency with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. Nevertheless we can also provide additional security if needed with the innovative nsd tupH surface area treatment. As opposed to standard paint it cannot flake off – an excellent advantage in harsh environments. Read here how Ever-Power Helical Geared Motors optimise creation at the chocolate manufacturer Zotter in Austria.
Ever-Power style for foot and flange installation. Gear housing machined on all sides for universal app.
Optimized gearing geometry here and in all the other versions results in excellent running smoothness. For special environmental conditions the gear unit can be installed with two shaft seals.
