FIELD: process engineering.SUBSTANCE: rolling mill roll 1 has two necks 2 of which, at least, one is equipped with sleeve locked against turning. Note here that roll neck sleeve is surrounded by bearing bush 9 fixed in pad 10. Note also that polygonal joint between roll neck 2 and neck sleeve 4 allows their relative locking against turning. Besides, thrust ring 11 with collar is arranged between neck sleeve 4 and bearing bush 9. Collar polygonal inner edge enters with geometrical closure the polygonal outer edge of step 5,15 of roll neck 2.EFFECT: new design of rolling mill.6 cl, 3 dwg |
