Description

2 75 378 Gdyby korba mechanizmu byla polaczona na stale z krzywka walcowa, to w stosunku do 1 cyklu (1 obrotu) podzial trwal by: ^r= 0,375 cyklu Dla zmniejszenia czasu podzialu, stanowiacego w cyklu czas pomocniczy, korba dzieki przekladni zebatej (kola Za, Z4, Z5, Z6) posiada 4-krotnie wieksze obroty niz krzywka walcowa; co 4-ty obrót korba obraca glowice wielopozycyjna 8. Stosunek obrotów korby mechanizmu maltanskiego do obrotów krzywki musi byc wielkoscia calkowicie podzielna. . _^_ZA Z6 T Z3 Z5 /c - przelozenie nk - obroty korby mechanizmu «b — obroty krzywki walcowej W przypadku omawianym: ic = 4 Zmiana pozycji glowicy odbywa sie po jej wycofaniu do tylu, co oznacza jednoczesnie wycofanie wiertel z otworów. Im ic jest wieksze, tym czas podzialu jest krótszy. PL2 75 378 If the mechanism crank was permanently connected with the cylindrical cam, then in relation to 1 cycle (1 revolution) the division would be as follows: ^ r = 0.375 cycle Za, Z4, Z5, Z6) has 4 times the rotation speed than a cylindrical cam; every 4th revolution the crank turns the multi-position head 8. The ratio of the crank turns of the Maltese mechanism to the rotation of the cam must be a quantity that is completely divisible. . _ ^ _ ZA Z6 T Z3 Z5 / c - ratio nk - rotation of the crank mechanism «b - rotation of the cylindrical cam In the case in question: ic = 4 The head is moved backwards, which means that the drill is withdrawn from the holes at the same time. The greater the value, the shorter the partition time. PL
