helical gear reducer

Helical geared motors will be the most standard and cost-effective solution for most drive applications. Helical equipment products are coaxial, where in fact the gear unit output shaft is good motor shaft. A solid shaft is at all times used as result shaft. Additional parts – e.g. gear tires or chain tires – to transfer the power to the powered load are therefore required. Solutions making use of helical geared motors can handle 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).

Efficient
High efficiency escalates the productivity of the application.
Hygienic
Ever-Power Helical Gear Models 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 answer: Our Helical Geared Motors
No two applications will be the same. Because of this, Ever-Power products 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 tested quality. This kind of geared motor is offered from Ever-Power in six sizes, in several stage variations with torque ranges from 50 to 700 Nm. We produce the gear wheels for helical equipment units from extremely wear-resistant, case-hardened steels.
Compact power packs
Our UNICASE Helical Geared Motors have a concise design, with an exceptionally robust grey cast iron housing. They include especially efficient motors in order to operate as effectively as possible, actually at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we positioned a higher priority on a smooth, easy to clean surface. This characteristic is especially very important to users in hygienically critical sectors like the meals or pharmaceutical industries.
Depending on the size of the gear unit, we create Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron casing. In this way you have optimum efficiency with every variant.
The aluminium casing of the Ever-Power series provides natural corrosion protection. Nevertheless we can also provide additional security if required with the innovative nsd tupH surface treatment. As opposed to conventional paint it cannot flake off – an excellent advantage in harsh environments. Read here how Ever-Power Helical Geared Motors optimise creation at the chocolate producer Zotter in Austria.
Ever-Power design for foot and flange installation. Gear housing machined on all sides for universal software.
Optimized gearing geometry here and in every the other versions results in excellent running smoothness. For unique environmental conditions the gear unit can be fitted with two shaft seals.
