Title

Abstract
(EN)

A device for coupling members such as driving and driven members so as to permit limited relative angular movement therebetween including a first member having an end with a bore extending thereinto, the bore having a polygonal shaped bore portion formed by a plurality of flat surfaces, a coupling portion on the other member having a polygonal shaped head formed by a plurality of side surfaces which are rounded axially and an end surface, the respective rounded surfaces on the head being engageable with respective flat surfaces of the polygonal shaped bore portion, a cross-bore through the first member intersecting the bore therein, and a cross-bore through the coupling portion in position to register with the cross-bore in the first member, a pin member extending through the registered bores to hold the members together and yet permit some relative angular movement therebetween, a bearing member positioned in the bore in the first member in position to engage the end surface of the head on the coupling portion when the members are connected together, the diameter of the coupling portion being somewhat smaller than the diameter of the bore in the first member so that the space formed therebetween limits the amount of possible relative angular movement therebetween.
