Drive shaft monobloc
Jansen Steel Tubes produces welded-drawn precision steel tubes made of high-tensile materials for one-part drive shafts. The tubes for the one-part drive shafts (monobloc) are cold-formed during manufacturing. For this reason, manufacturers of monobloc drive shafts greatly value identical reshaping properties and high levels of dimensional stability in the delivery condition of the tubes. Additionally, after inductive hardening, high strength values with low levels of surface decarburisation are required. The trend towards light-weight design increasingly demands high-strength materials, which allow weight reductions with comparable physical properties.
Tube requirements
■ Very good formability
■ High torsional strength and durability
■ Excellent hardening properties
■ High geometrical accuracy (eccentricity, roundness)
■ Excellent surface condition
