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.
Claims18
A rolling stand for rolling a metallic rolling stock, comprising:
- a roll having two roll journals;
- two chocks each having a cylindrical receiving space for rotationally supporting the respective roll journal of the roll, wherein the receiving space has at least one high-pressure inlet for coolant and/or lubricant at least in one of the two chocks in a region of a maximum load;
- at least one high-pressure pump associated with the at least one of the two chocks, wherein the at least one high-pressure pump has a drive shaft;
- a high-pressure conduit for connecting an outlet side of the high-pressure pump with the at least one high-pressure inlet for feeding the coolant and/or lubricant into the receiving space;
- and
- drive means provided on a side of the at least one of the two chocks remote from a roll face, wherein the drive means connect the drive shaft of the at least one high-pressure pump with the respective roll journal, such that rotation of the roll journal causes a rotation of the drive shaft of the at least one high-pressure pump, wherein the drive means comprises a gear drive having a pinion and a drive gear connected with the respective roll journal for joint rotation therewith and rotationally connected directly or indirectly with each other, and in that the pinion is mounted on a free end of the drive shaft of the high-pressure pump for joint rotation therewith, or the free end of the drive shaft is formed as the pinion, and
- the drive gear is an externally toothed ring gear connected with the respective roll journal or with a bearing sleeve fixedly mounted on the respective roll journal for joint rotation therewith on the side thereof remote from the roll face, and the high-pressure pump is arranged that the drive shaft pinion directly engages the externally toothed ring gear.
