Elastic coupling and elastomeric element therefor
View Patent ↗An elastic coupling having two coupling sections is provided. A first coupling section has a plurality of spaced-apart pockets disposed along an arc. Elastomeric elements are positively held in the pockets, and the second coupling section has projections that extend into the first coupling section respectively between two adjacent elastomeric elements. The elastomeric elements comprise two regions having different properties. The first region, which extends radially and is held in the pockets of the first coupling section via its ends, is more inherently stable than is the second region for the transmission of a peripheral force. The second region, which respectively faces one of the projections of the second coupling section, is more yielding than is the first region such that deformations can be introduced into the second region with the effect of a slight restoring force.
1. An elastic coupling comprising:
a first coupling section having a plurality of spaced-part pockets that are disposed along an arc;
a second coupling section having projections; and elastomeric elements that are respectively positively held in said pockets, wherein said projections of said second coupling section respectively extend into said first coupling section between two adjacent ones of said elastomeric elements, wherein each elastomeric element comprises a first region and a second region each having different properties, wherein said first region extends radially and has ends that are held in said pockets, wherein said first region is more inherently stable than is said second region to transmit a peripheral force, wherein said second region faces one of the projections of said second coupling section and is more yielding than is said first region such that deformations can be introduced into said second region, and wherein said second more yielding region of said elastomeric element comprises two protrusions that at a level of said projection of said second coupling section are laterally formed on said first, more inherently stable region.
2. An elastic coupling according to claim 1 , wherein said first region and said second region of said elastomeric element are interconnected in a material-positive manner by means of vulcanization.
3. An elastic coupling according to claim 2 , wherein each of said protrusions of said second region is provided on an inwardly disposed side with in undercut profile, and wherein said second region, in addition to said material-positive connection, positively engages said first region via said undercut profiles in a manner of a toothing.
