Helical geared motors are the most standard and cost-effective solution for many drive applications. Helical equipment systems are coaxial, where the gear unit output shaft is good motor shaft. A good shaft is always used as result shaft. Additional parts – e.g. gear tires or chain wheels – to transfer the pressure to the powered load are for that reason required. Solutions making use of 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).

Always the right option: Our Helical Geared Motors
No two applications will be the same. Due to this, Ever-Power items three different drive solutions with helical gear units. All variants can be found as flange or foot/flange mounted versions.
The all-rounder
Standard Helical Geared Motors have a wide variety of uses and offer proven quality. This type of geared motor is obtainable 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 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 are equipped with especially efficient motors to be able to operate as effectively as possible, also at the maximum torque of 26,000 Nm.

Easy maintenance: Wash-down able helical geared motors
With the Ever-Power series we placed a higher priority on a smooth, simple to clean surface. This characteristic is especially very important to users in hygienically essential sectors such as the food or pharmaceutical industries.
Based on the size of the apparatus unit, we produce Ever-Power Helical Gear Units with a die cast aluminium or grey cast iron housing. In this way you have optimum overall performance with every variant.
The aluminium housing of the Ever-Power series provides natural corrosion protection. However we can also provide additional safety if necessary with the innovative nsd tupH surface treatment. As opposed to regular paint it cannot flake off – an excellent advantage in harsh environments. Read right 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 casing machined on all sides for universal program.
Optimized gearing geometry here and in all the other models results in excellent running smoothness. For particular environmental conditions the gear unit can be fitted with two shaft seals.
