Abstract
A thermally stressed rotary connection of two coaxially aligned shafts includes two metallic coupling sleeves which are connected with the shafts by way of elastic intermediate layers. The two metallic sleeves engage one another. A ceramic centering sleeve is provided radially around the outside of the coupling sleeves and is shrunk onto the two shafts. The arrangement has the advantage of an effective connectability of different shafts such as ceramic or metal, in which case the two shafts may be connected with one another during the mounting. This allows undivided housings to be used.
Claims18
A thermally and mechanically stressed, torsional rigid connection between two coaxially aligned shafts, comprising:
- a first shaft shoulder formed on an end of one of said two coaxially aligned shafts,
- a second shaft shoulder formed on an end of the other of said two coaxially aligned shafts, said first and second shaft shoulders being situated opposite one another;
- first and second elastic intermediate layers formed on said first and second shaft shoulders, respectively;
- two metallic coupling sleeves engaging one another, one of said two metallic coupling sleeves being fastened to said one coaxially aligned shaft through said first intermediate layer and the other metallic coupling sleeve being fastened to said other coaxially aligned shaft through said second intermediate layer;
- and
- a ceramic centering sleeve surrounding said two metallic coupling sleeves and shrunk onto said two coaxially aligned shafts.
