Depending on the size of the inline helical gearboxes, we produce Helical Gear Units with a die-cast aluminum or grey cast iron housing. In this way, you obtain optimum performance with every variant. The inline helical gearboxes are produced in three series and many sizes for a wide range of applications. Motors with an inline helical gearbox from Ever-Power have a high power density and many options.

Helical Inline Gearboxes

Outstanding Features of Inline Helical Gearboxes

  • Powerful: Our inline helical gearboxes provide a maximum torque of 26,000 Nm (as an Industrial gear unit up to 250.000 Nm).
  • Efficient: High efficiency increases the productivity of the application.
  • Hygienic: Ever-Power Helical Gear Units have wash-down capability thanks to their smooth surfaces.
  • Robust: We can make inline helical gearboxes with motors in corrosion protection, which also withstands aggressive cleaning agents.
  • Easy maintenance: Wash-down capable helical geared motors. We placed a high priority on a smooth, easy-to-clean surface. This characteristic is essential for users in hygienically critical sectors such as the food or pharmaceutical industries.

No two applications are the same. Because of this, Ever-Power supplies several different drive solutions with helical gear units. All variants are available as flange or foot/flange mounted versions.

Helical Inline Gearbox

R Series Inline Helical Gearbox

Our R-Series inline helical gearboxes feature a graded cast iron housing and high strength steel gears. This series of helical gearboxes can be powered by either DC or AC power. For safe operation, helical gearboxes are fireproof with a brake motor option. As a leading manufacturer of inline helical gearboxes, we understand the convenience and efficiency guaranteed by inline transmissions. All of our inline helical gearboxes and motors are easy to maintain and replace. With our inline helical gearboxes, you can obtain a wide range of output torques (200 - 1800 Nm), ratios (3.33 - 287.74), mounting positions (M1 - M6) and power ratings (0.18 kW - 160 kW). A wide range of inline helical motor/gearboxes is available. R series inline helical gearboxes are made of high rigidity ribbed cast iron body; hardened gears are made of high quality alloy steel with carburized and quenched hardened surface and finely machined ground teeth for smooth transmission, low noise, high load capacity, low temperature rise and long service life. R series inline helical gear coaxial helical inline gearboxes are widely used in metallurgy, sewage treatment, chemical industry, pharmaceutical industry, etc. R series helical inline gearboxes are usually installed vertically. The size and type of lubricant used in R helical gearboxes is important. Vertical mounting causes gearbox gear oil to leak when the gearbox stops working.
