Abstract
Obrotowy nóż kombajnowy charakteryzuje się tym, że w kołnierzu oporowym (1b) trzonka (1c) noża (1) wykonane jest wycięcie (1a) o promieniu przejścia R korzystnie większym lub co najmniej równym 0,25 • (D - d), w którym osadzona jest trwale wkładka odciążająca (2) w postaci pierścienia wykonanego korzystnie z materiału odpornego na naciski i zużycie ścierne. Sposób zwiększenia trwałości noża kombajnowego polega na tym, że nóż (1) z wykonanym wycięciem (1a) umieszcza się częścią stożkową w gnieździe (9) podstawy (3) z wysokocierną wykładziną (6), następnie wsuwa się wkładkę odciążającą (2) w wycięcie (1a) kołnierza oporowego (1b) trzonka (1c) noża (1) od strony jego części chwytowej, po czym opuszcza się głowicę (4) z rolkami (5) do styku z krawędzią kołnierza oporowego (1b) tak, aby nacisk wzdłużny głowicy (4) oraz jej ruch obrotowy wokół osi (10) formował kształtowo krawędź kołnierza oporowego (1b), aż do jej zaciśnięcia na wkładce odciążającej (2).The rotary combine knife is characterized in that a cutout (1a) with a transition radius R preferably greater than or at least equal to 0.25 • (D - d) in the stop collar (1b) of the knife shaft (1c) the relieving insert (2) is permanently mounted in the form of a ring made preferably of a material resistant to pressure and abrasive wear. The way to increase the durability of the combine knife is that the knife (1) with the cutout (1a) is placed in the conical part in the socket (9) of the base (3) with the high-friction lining (6), then the strain relief insert (2) is inserted into the cutout (1a) the stop flange (1b) the shank (1c) of the knife (1) from its grip side, then the head (4) with rollers (5) is lowered to contact the edge of the stop flange (1b) so that the longitudinal pressure of the head (4) and its rotational movement around the axis (10) formed the edge of the stop collar (1b), until it was tightened on the relief insert (2).
