Cardan-type joint including supportive compression bars

A joint for connection of two shafts with one another which is axially and/or angularly movable within certain limits comprising:

• flanges which are, in each case, arranged at ends of the two shafts connected by the joint,
• three driving pins axially projecting in the direction of the joint on each of the flanges to provide six mutually staggered driving pins uniformly arranged on a circumference of a common graduated circle,
• a flexible, regularly polygon-type, joint ring which connects the driving pins with one another, and which is provided with sockets at corner points, said joint ring being axially elastically deformable between the sockets,
• the joint ring, in turn, being formed in several parts by several closed oval driving loops, each winding around two adjacent sockets, and each of which can be radially swivelled on the sockets so that a shape of the joint ring can be changed in a flexible manner, and
• one linear compression bar respectively mounted in an interior of each of the oval driving loops, said compression bar being provided on two ends thereof with a supporting surface adapted to the sockets,
• wherein an effective length of the compression bars is dimensioned such that the compression bars fill a clear space between two adjacent sockets with play.

A joint for flexible connection of two shafts with one another comprising:

• flanges arranged at ends of the shafts connected by the joint,
• a plurality of driving pins projecting from each of the flanges to provide mutually staggered driving pins uniformly arranged on a circumference of a common graduated circle,
• a flexible polygonal joint ring which connects the driving pins with one another by sockets received by the pins at corner points, said joint ring being axially elastically deformable between the sockets, the joint ring being formed by closed oval driving loops, each of said loops winding around two adjacent sockets and radially swivelling on the sockets as a shape of the joint ring is changed, and
• a compression bar respectively mounted within each of the oval driving loops, said compression bar being provided on opposite ends thereof with supporting surfaces engageable with the adjacent sockets,
• wherein each compression bar absorbs load only after a load-caused elastic lengthening of a plurality of said driving loops.
