Helical geared motors are the most typical and cost-effective solution for many drive applications. Helical equipment models are coaxial, where in fact the gear unit output shaft is in line with the motor shaft. A solid shaft is constantly used as output shaft. Additional parts – e.g. gear tires or chain wheels – to transfer the pressure to the driven load are consequently required. Solutions making use of helical geared motors can handle an extremely variable speed range.
SIMOGEAR helical geared motors are available for the power 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 a wide range of applications
Motors with a helical gear unit from Ever-Power have a high power density and a large number of choices. The apparatus units are produced in three series and many sizes for an array of applications.
Ever-Power Helical Gear Systems impress with outstanding features:
Powerful
Our helical gear units provide a maximum torque of 26,000 Nm (since an Industrial gear unit up to 250.000 Nm).
Efficient
High efficiency escalates the productivity of the application form.
Hygienic
Ever-Power Helical Gear Devices have wash-down capability thanks to their smooth surfaces.
Robust
If required, we are able to treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Safety, which also withstands aggressive cleaning agents.
Always the right alternative: Our Helical Geared Motors
No two applications are the same. Due to this, Ever-Power supplies three different drive solutions with helical gear units. All variants can be found as flange or foot/flange mounted versions.
The all-rounder
Regular Helical Geared Motors have a wide variety of uses and offer verified quality. This kind of geared motor is offered from Ever-Power in six sizes, in two or three stage variations 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 housing. They are equipped with especially efficient motors to be able to operate as efficiently as possible, actually at the utmost torque of 26,000 Nm.

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we placed a higher priority on a smooth, simple to clean surface. This feature is especially important for users in hygienically vital sectors such as the meals or pharmaceutical industries.
Based on the size of the apparatus unit, we generate Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron casing. In this way you obtain optimum overall performance with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. However we can also provide additional protection if required with the innovative nsd tupH surface area treatment. In contrast to typical paint it cannot flake off – a great advantage in harsh environments. Read here how Ever-Power Helical Geared Motors optimise production at the chocolate producer Zotter in Austria.
Ever-Power design for foot and flange installation. Gear casing machined on all sides for universal software.
Optimized gearing geometry here and in all the other versions results in excellent running smoothness. For special environmental conditions the apparatus unit can be installed with two shaft seals.
