helical gear reducer

Helicoidal motorreductores are the most standard and cost-effective solution for many drive applications. Helical gear systems are coaxial, where in fact the gear unit output shaft is good motor shaft. A good shaft is constantly used as result shaft. Additional parts – e.g. gear tires or chain wheels – to transfer the pressure to the driven load are therefore required. Solutions making use of helical geared motors are capable of an extremely variable speed range.
SIMOGEAR helical geared motors are for sale to the power range up to 20 HP (15 kW) and rated gear device 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 possess a higher power density and a sizable number of options. The apparatus units are stated in three series and several sizes for a wide variety of applications.
Ever-Power Helical Gear Devices impress with excellent features:
Powerful
Our helical gear units give a maximum torque of 26,000 Nm (because an Industrial gear unit up to 250.000 Nm).
Efficient
High efficiency increases the productivity of the application.
Hygienic
Ever-Power Helical Gear Devices have wash-down capability thanks to their smooth surfaces.
Robust
If required, we can treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Protection, which also withstands intense cleaning agents.
Always the right answer: Our Helical Geared Motors
No two applications are the same. Because of this, Ever-Power materials 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 a wide range of uses and offer tested quality. This kind of geared engine is available 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 compact design, with an extremely robust grey cast iron housing. They include especially efficient motors in order to operate as effectively as possible, even at the maximum 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, easy to clean surface. This characteristic is especially important for users in hygienically important sectors like the food or pharmaceutical industries.
Based on the size of the apparatus unit, we produce Ever-Power Helical Gear Systems with a die cast aluminium or grey cast iron housing. In this way you obtain optimum efficiency with every variant.
The aluminium casing of the Ever-Power series provides organic corrosion protection. However we can also provide additional protection if necessary with the innovative nsd tupH surface treatment. In contrast to typical paint it cannot flake off – a great advantage in harsh environments. Read right here how Ever-Power Helical Geared Motors optimise creation at the chocolate producer Zotter in Austria.
Ever-Power style for foot and flange installation. Gear casing machined on all sides for universal program.
Optimized gearing geometry here and in all the other versions results in exceptional running smoothness. For unique environmental conditions the gear unit can be installed with two shaft seals.
