Abstract
The invention relates to a rolling stand for the rolling of metallic rolling stock. The rolling is achieved with the aid of a roll of which the two roll journals (112) are rotatably mounted in recesses (122) of chocks (120). The recesses are supplied with coolant and/or lubricant via a high-pressure inlet (124) and at least one low-pressure inlet (126). The high-pressure inlet is fed via high-pressure conduits (132) from a high-pressure pump (130). To reduce the costs for driving the high-pressure pump in relation to the prior art, the invention provides that the high-pressure pump is rotationally coupled to the roll journal via a gear mechanism in order to be driven thereby.
Claims10
A rolling stand for rolling of, preferably, a metallic rolling stock;
- comprising:
- a roll (100) having two roll journals (112);
- two chocks (120) each having a cylindrical receiving space (122) for rotationally supporting a roll journal (112) of the roll (100), wherein the receiving space has at least one high-pressure inlet (124) for coolant and/or lubricant at least in one of the two chocks (120) in a region of a maximum load;
- at least one high-pressure pump (130) associated with the at least one of the two chocks (120);
- a high-pressure conduit (132) for connecting an outlet side of the high-pressure pump (130) with the at least one high-pressure inlet (124) for feeding the coolant and/or lubricant into the receiving space (122),
- characterized by
- a drive connection (140) provided on a side of the chock (120) remote from a roll face for rotationally connecting the high-pressure pump (130) with the roll journal (112) rotationally supported in the receiving space (122).
