A roll stand for rolling metallic strips includes at least one roll or cylinder which is respectively mounted in a mounting on rolling bearings in the region of its end journals, and at least one distributing device for distributing a lubricant-gas flow. The roll stand according to the invention makes it easily possible in an operationally reliable manner to supply a rolling bearing, provided for mounting a roll or cylinder, with a precisely determined amount of lubricant. This is achieved according to the invention in that a connecting channel for the transport of a lubricant-gas flow to or from the distributing device is molded into the roll or cylinder.

An installation piece for supporting a roller in a roller stand of a roller frame. The installation piece includes a main bore for receiving a journal of the roller, an inlet for a lubricant, an outlet for the lubricant, and a pump device for pumping the lubricant leaving the installation piece through the outlet. The pump device has a housing, an inlet channel, and an outlet channel. The inlet channel communicates with the inlet and the outlet channel communicates with the outlet for the flow of the lubricant. The pump device is driven by the flow of the lubricant in the inlet. The housing of the pump device is equipped with a screw pump and a turbine, which is driven by the pressurized inflowing lubricant, in the inlet channel for driving the screw pump.

The invention relates to a mounting piece (1) for receiving a roll neck of a roll used in steel and non-ferrous metal processing having at least one lubricant- receiving chamber (7) on a roll body side (3) and at least one lubricant- receiving chamber (8) on a discharge side (4) which are located beneath a lowest support point (9), connection bores (10) between the lubricant-receiving chambers (7, 8) on the roll body and discharge sides (3, 4), wherein the lubricant (2) is collected in additional lubricant-receiving chambers (15, 16) in the mounting piece (1).
摘要:
A lubricating structure of a bearing for lubricating a bearing by supplying oil air which is transmitted with pressure through respective distribution passages of an oil air distributor from an oil air supply apparatus to the bearing, comprising a first lubrication route for supplying the oil air to the bearing to lubricate inner portion of the bearing; and a second lubrication route for supplying the oil air to the bearing, and leading this oil air to a fit portion between the internal diameter surface of the inner race and the shaft portion through a seal member having a predetermined void portion, thereby lubricating this fit portion.
摘要:
A hoseless lubrication arrangement for the work rolls of a rolling mill including a pair of cooperating wall portions on an adapter on the balancing piston and on an adapter on the work roll chock, the wall portions being in opposed relation when the work roll chock is supported on the balancing piston within the mill housing. A lubrication passage extends from a supply fitting on the adapter on the balancing piston through the same and across the wall portions which are sealed and through the work roll chock into communication with the work roll bearing therein. The lubrication passage is automatically disconnected from the position interconnecting the fitting and the bearing when the work roll chock is removed from the mill housing and is automatically reconnected when a work roll chock is installed in the mill housing on the balancing piston.
