Abstract

Tooth holder 1 and tooth 15 for digger buckets, rotating ground-working machinery and the like, where the tooth holder, which is connected to the digger bucket or the like, has a projection 4 intended to be received in a hollow or recess 17 in the root part of the tooth, and the tooth holder has holes for pins fixing the tooth on the tooth holder, and where the projection 4 of the tooth holder is provided with preferably two raised ridges 7, 8 which are located opposite each other, run parallel with the direction of assembly and have inwardly inclined sides 9, 10, which ridges are designed to be received in elongate grooves 20, 21 which are formed in the walls of the tooth recess, with walls sloping outwards from the base of the groove. The novel feature is that the elongate ridges 7, 8 and/or the elongate grooves 20, 21 cooperating with these narrow in the direction of assembly so as to generate a pre- stressing wedging effect when the tooth 15 and tooth holder 1 are driven together. <IMAGE>
