Karl Kutzbach

from Wikipedia, the free encyclopedia

Franz Karl Kutzbach (born March 19, 1875 in Trier , † April 25, 1942 in Dresden ) was a mechanical engineer and scientist. Professor at the TH Dresden since 1913 , he mainly researched the further development of gear drives and created, among other things, the Kutzbach Plan .

Life

Kutzbach was the child of a merchant family, his brother was the Trier city curator Friedrich Kutzbach . Karl Kutzbach grew in the then Prussian Trier and completed his schooling in 1893 with the Abitur at the Friedrich-Wilhelm Gymnasium from. He then studied mechanical engineering at the Technical Universities of Aachen and Berlin from 1893 to 1897 . As a student, Kutzbach became a member of the Catholic associations of the KV , in Aachen with the Carolingia, in Berlin with the Burgundia, now KStV Askania-Burgundia . He later became an honorary philistine of the Saxo-Lusatia KV association in Dresden.

After completing his studies, Kutzbach was initially an assistant to Professor Alois Riedler at the TH Berlin and dealt with piston machines . From 1900 to 1913 he worked as a specialist for combustion engines in a design office at MAN .

The Technical University of Dresden appointed Kutzbach as full professor for machine elements on October 1, 1913 , making him the first person ever to hold this chair in the mechanical department. In 1917, because of the First World War , he was drafted into the aircraft maintenance facility in what is now the Berlin district of Adlershof . It was stationed at the Johannisthal airfield and used the facilities of the German Aviation Research Institute during the war . By the end of his term of service in December 1918, Kutzbach gained experience with aircraft engines , which he also published in 1921.

In 1919, Kutzbach became director of the mechanical engineering department of the materials testing office of the TH Dresden and continued the gear research established at the university by Richard Stribeck . He was primarily concerned with the further development of gears and V-belts and also worked on the improvement of continuously variable transmissions , clutches and universal joints . One of his main achievements is the Kutzbach plan named after him , a graphic process with the help of which the determination of the rotational speed and speed of the components of planetary gears was greatly simplified.

In addition, from 1922 onwards, Kutzbach made great contributions in the field of standardization of springs and gears. Among other things, the DIN standards 870 and 867 go back to him, with which he made a contribution to the further development of involute gearing, for example in bevel gears . The Technical University of Hanover awarded him an honorary doctorate in 1928 . From a correspondence with the Göttingen fluid mechanic Ludwig Prandtl it emerges that Kutzbach began to deal with rocket technology from 1930, and thus very early on .

In November 1933, Karl Kutzbach signed the German professors' commitment to Adolf Hitler . He died in Dresden in 1942 . In 1961 the Kutzbach-Bau was named after him, a building of the TU Dresden erected from 1958 , in which today the institutes for fluid technology as well as for machine tools and control technology are located.
