Quenched and tempered steel
Splined shafts in the new material
Mädler, a wholesaler and manufacturer of drive and mechanical engineering elements, is expanding its range of splined shaft connections with new splined shafts made from 42CrMo4 heat-treated steel.
According to the company, the new material ensures that either the dimensions of the splined shafts can be reduced or their load-bearing capacity increased. This should make the high-strength splined shafts suitable for transmitting large and varying torques, for example in indexing shaft gears for machine tools. At the same time, they contribute to greater energy efficiency in machine and special machine construction. In addition to splined shafts made of C45 and 1.4301 stainless steel, Mädler now also offers splined shafts made of 42CrMo4 in its product range.
Due to its special material properties, the quenched and tempered steel allows a higher yield strength, flexural fatigue strength and surface pressure, which means that the load on the splined shaft can be increased or reduced in the design. Due to lower mass forces, energy savings as well as higher accelerations and faster speed changes are possible. In addition, splined shafts made of 42CrMo4 are suitable for high torsional forces with axial displaceability and therefore offer numerous possibilities in special machine construction. as
