Speedy steep thread spindles

Sprint and marathon in symbiosis: screw drives with extreme gradients achieve top speeds in endurance running

Never before have such high travel speeds been achieved at such low speeds as with the Speedy lead screws from Eichenberger. Extreme pitches of up to six times the diameter also meet the highest demands for efficient conversion of linear movements into rotary movements. As an innovative drive solution, the lead screw drives can also replace toothed belt drives, as they can be freely accelerated and positioned and operate independently of a second energy source. Thanks to their good efficiency and convincing price/performance ratio, they are an ideal alternative to trapezoidal or ball screw spindles for certain applications.

Design features

The lead screws with up to oversquare thread pitches (p ≤ 6xd) are manufactured from corrosion-protected steel using the cold rolling process and combined with highly wear-resistant technopolymer flange nuts in non-preloaded or preloaded versions. With low to medium load ratings, they are ideal for low to medium loads. For higher loads or special applications, bronze or alternative technopolymers are also used for nuts. The finest surface quality of the steel lead screws and nuts made of high-performance technopolymer enable a very high degree of efficiency.

  • Small to medium load ratings
  • Very high travel speeds
  • High efficiency (η ≈ 0.5 ....0.8)
  • Weight optimization possible through
  • Aluminum spindles
  • Performance optimization possible through
  • Coating
  • High reliability
  • Low maintenance and long service life

Application examples for Speedy lead screws

In medical and food applications as well as in building services engineering, the materials of the screw drives must meet essential basic requirements. Thanks to the smooth surface of the outstanding stainless steel material and - because it is rolled and not ground - Eichenberger achieves greater strength and a more homogeneous surface. This results in significantly less wear and longer service life, less vibration and virtually noiseless operation.

Speedy helical screw drives are primarily used where extremely high travel speeds are required. Thanks to the extreme lead angles, we achieve maximum efficiency - in the smallest possible installation space.
