helical gear reducer

Helical geared motors will be the most conventional and cost-effective solution for many drive applications. Helical equipment products are coaxial, where in fact the gear unit output shaft is based on the motor shaft. A good shaft is generally used as output shaft. Additional parts – e.g. gear tires or chain wheels – to transfer the drive to the powered load are consequently required. Solutions utilizing helical geared motors are capable of 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 an array of applications
Motors with a helical gear unit from Ever-Power have a high power density and a sizable number of options. The apparatus units are stated in three series and several sizes for a wide range of applications.
Ever-Power Helical Gear Products impress with exceptional features:
Powerful
Our helical gear models 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 thanks to their smooth surfaces.
Robust
If required, we are able to treat Ever-Power Helical Geared Motors with nsd tupH Corrosion Protection, which also withstands aggressive cleaning agents.
Always the right solution: Our Helical Geared Motors
No two applications are the same. Because of this, Ever-Power supplies three different drive solutions with helical equipment units. All variants are available as flange or foot/flange mounted versions.
The all-rounder
Standard Helical Geared Motors have a wide range of uses and offer verified quality. This kind of geared motor is obtainable from Ever-Power in six sizes, in several stage versions with torque ranges from 50 to 700 Nm. We produce the apparatus wheels for helical gear units from highly 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 are equipped with especially efficient motors in order to operate as efficiently as possible, also 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, simple to clean surface. This feature is especially very important to users in hygienically important sectors like the meals or pharmaceutical industries.
Based on the size of the apparatus unit, we produce Ever-Power Helical Gear Models with a die cast aluminium or grey cast iron housing. In this way you have 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 area treatment. As opposed to conventional paint it cannot flake off – an excellent advantage in harsh conditions. Read right here how Ever-Power Helical Geared Motors optimise production at the chocolate producer 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 models results in extraordinary running smoothness. For unique environmental conditions the apparatus unit can be fitted with two shaft seals.
