High helix leadscrew | Eichenberger Gewinde AG

Never before have such high travel speeds been achieved with such low rotational speeds as with the Eichenberger Speedy high-helix leadscrew. Extreme pitches of up to six times the diameter also meet the most challenging demands for efficient conversion of linear to rotary motion. High-helix leadscrews can also be used as innovative drive solutions to replace toothed belt drives, as they can be freely accelerated and positioned and operate without a second energy source. The good efficiency and price/performance ratio make them an ideal alternative to trapezoidal or ball screws for certain applications.

Design features

Leadscrews with high helix pitches bigger than the screw diameter (p ≤ 6xd) are manufactured from corrosion-protected steel by a cold rolling process and are combined with wear-resistant technopolymer flanged nuts in non-preloaded or preloaded versions. They are ideal for low to medium loads with small to mid-load capacity. Nuts made from bronze or alternative technopolymers can be used for higher loads or special applications. The finest surface quality of the steel leadscrews and high-performance technopolymer nuts enable very high efficiency levels.

Small to medium load ratings
Very high travel speeds
High efficiency (η ≈ 0,5 ... 0,8 )
Weight optimisation with aluminium spindles
Performance optimisation coating
Highly reliable
Low maintenance and long service life

Application examples for Speedy leadscrews

The materials used for screw drives in medical and food applications or building technology must meet essential basic requirements. The smooth surface of the excellent stainless steel material and the rolling process replacing grinding enables Eichenberger to produce higher strength and more homogeneous surfaces. This results in significantly less wear, longer service life, less vibration and virtually silent operation.

Speedy leadscrews are mainly used when extremely high travel speeds are required. Maximum efficiency thanks to extreme pitch angles - in the smallest installation space.
