COUPLING FOR EXCAVATOR TEETH AND THE LIKE

摘要

The coupling between the excavator tooth and the tooth-holder is achieved by combining three successive areas from the medial part of the coupling piece to its free end, comprising a first area of straight stepped guides which open at the side external surfaces of the coupling piece followed by an area of guiding by means of revolution surfaces opposite to each other, and a third terminal area formed like a prismatic rod of which the axis coincides with t he piece axis.
