FIELD: mechanical engineering. SUBSTANCE: invention relates to earth-moving machines, namely, to buckets of excavators, scrapers, posts of rippers, teeth of milling machines and machines for making slits in soil, etc. proposed method includes inter-connection of different elements of tooth made of materials of different wear resistance. Each tooth component is fitted one into the other in sequence and welded over perimeter of extreme mated components of tooth. Connection of inner part of one surface of tooth element with the other following the outer part of adjoining surface of other element of tooth is made by heating. EFFECT: improved efficiency of connection of contacting surfaces. 2 dwg |
