Technological Evolution

A continuous evolution technology in both machinery and production methods made it possible for Hansen to develop gear units that transmit more power than those -similar in size- of a previous range.

  • exceptional torque capacity
  • minimal noise level
 

HANSEN P4 SINGLE STAGE

  • unmatched balance between mechanical, thermal and bearing rating
  • variable centre distances
  • specific macro gear geometry
  • shafts in horizontal or vertical plane

Today

Thanks to the evolution in technology, and the continuous investment policy of Hansen to keep up with the latest and most advanced techniques, each generation of Hansen gear units brought along a significant power squeeze and a remarkable loss in weight.

Today, Hansen is offering the highest power ratings for a given weight or size of gear unit.

Factors

Factors that have made this evolution possible:

  • High performance alloy steels in combination with optimal heat treatment: case carburising.

  • Use of high precision machines in the manufacturing process of housings and gears.

  • Parallel development towards increased performance of bearings.

  • Continuous investment in engineering know-how to optimise design concepts: e.g. use of short integral pinionshafts.
