helical gear reducer

Helical geared motors will be the most regular and cost-effective solution for many drive applications. Helical gear systems are coaxial, where in fact the gear unit result shaft is based on the motor shaft. A solid shaft is often used as result shaft. Additional elements – e.g. gear tires or chain wheels – to transfer the pressure to the powered load are for that reason required. Solutions utilizing helical geared motors can handle an exceptionally variable speed range.
SIMOGEAR helical geared motors are available for the energy range up to 20 HP (15 kW) and rated gear device 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 higher priority on a smooth, easy to clean surface. This characteristic is especially very important to users in hygienically vital sectors such as the food or pharmaceutical industries.
Depending on the size of the apparatus unit, we generate Ever-Power Helical Gear Products 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 organic corrosion protection. However we can provide additional safety if necessary with the innovative nsd tupH surface area treatment. As opposed to regular paint it cannot flake off – a great advantage in harsh conditions. Read 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 casing machined on all sides for universal program.
Optimized gearing geometry here and in every the other models results in remarkable running smoothness. For particular environmental conditions the apparatus unit can be installed with two shaft seals.
