helical gear reducer

Helical geared motors are the most standard and cost-effective solution for many drive applications. Helical gear units are coaxial, where the gear unit result shaft is good motor shaft. A solid shaft is constantly used as result shaft. Additional elements – e.g. gear wheels or chain tires – to transfer the force to the driven load are therefore required. Solutions utilizing helical geared motors are capable of an exceptionally 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).

Easy maintenance: Wash-down capable helical geared motors
With the Ever-Power series we positioned a high 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.
Depending on the size of the gear unit, we generate Ever-Power Helical Gear Products with a die cast aluminium or grey cast iron housing. In this way you obtain optimum functionality with every variant.
The aluminium housing 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. In contrast 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 mounting. Gear housing machined on all sides for universal application.
Optimized gearing geometry here and in every the other models results in extraordinary running smoothness. For unique environmental conditions the gear unit can be installed with two shaft seals.
