Appl. No.:

09/736965

Inventors:

Ronald Plesh - Orchard Park NY, US

International Classification:

F16C019/54

US Classification:

384/490000, 384/454000

Abstract:

A bearing cartridge which is constructed not to be disassembled for re-packing with grease or otherwise and which may be quickly and easily replaced in the field. For high temperature applications such as sinter or pellet car wheels, the bearing cartridge is lubricated by a high temperature solid lubricant, and the rolling elements preferably comprise cylindrical rolling elements for bearing radial loads and spherical rolling elements for bearing axial loads. For ultra high temperature applications such as furnace car wheels, the bearing cartridge is lubricated by a ultra high temperature lubricant composed of a graphite and molydenum paste. In order to economically provide small furnace car bearing cartridges, a two-piece bearing cartridge is provided with rolling elements, preferably having cylindrical central portions for bearing radial loads and conically shaped axially outer end portions for bearing axial loads, between the races, the rolling elements insertable by means of a feeder slot.

Inventors:

Ronald Plesh - Orchard Park NY, US

International Classification:

B21B013/14

US Classification:

072/241200

Abstract:

A roller assembly for use as a back-up roller for work rolls. The roller assembly comprises an axle, a roller rotatably mounted on the axle, a plurality of bearing elements rotatably positioned between the axle and roller, and at least one bushing which is eccentric to the axle and which is fixedly mounted on the axle. The eccentric bushing is rotatable for translating the roller in a radial direction thereof. In order to rotate the bushing in one of opposite circumferential directions, preferably, force is applied to a respective one of a pair of terminal ends of a groove which extends circumferentially in a radially outer surface of the eccentric bushing. Each of the axle and roller, which serve as inner and outer races respectively, preferably has a thickness radially of at least about 1 inch to provide high bearing capacity.

US Classification:

Abstract:

A roller assembly for use as a back-up roller for work rolls. The roller assembly comprises an axle, a roller rotatably mounted on the axle, a plurality of bearing elements rotatably positioned between the axle and roller, at least one bushing which is eccentric relative to the axle and which is fixedly mounted on the axle by a dowel which passes through holes in the axle and eccentric bushing, and a housing for the bushing. The eccentric bushing is rotatable for translating the roller in a radial direction thereof. In order to rotate the bushing in one of opposite circumferential directions, force is applied to a respective one of a pair of terminal ends of grooving, preferably a single groove, which extends circumferentially in a radially outer surface of the eccentric bushing and which is adapted to allow unimpeded movement of adjustment screws in apertures in the housing to adjustably engage the grooving terminal ends thereby to maximize roller translation effected by the apertures and screws and positions of the terminal ends. The eccentric bushing passages (and/or the axle passages) through which the dowel passes are oblong to allow each bushing to independently move circumferentially relative to the other bushing within the limits of the oblong passages, to enable compensation for slight misalignment between the work roll and the back-up roller for the purpose of achieving near perfect contact.

International Classification:

B65G013/00

US Classification:

193/03500R, 193/037000, 193/0350SS

Abstract:

An inexpensive, high capacity, and easy to install roller () for engaging hot metal plates being transferred over a cooling bed plate transfer grid. An invertible block which may have a bearing is provided at each end of the axle () for the roller. The bearing block () is received in a cut-out in the upper edge of a respective elongate parallel grid member. The bearing block () is clamped in the cut-out by a plate which is received in a pair of slots in forward and aft edges of the cut-out to clampingly overlie the bearing block ().

An inexpensive, high capacity, and easy to install roller for engaging hot metal plates being transferred over a cooling bed plate transfer grid. An invertible block which may have a bearing is provided at each end of the axle for the roller. The bearing block is received in a cut-out in the upper edge of a respective elongate parallel grid member. The bearing block is clamped in the cut-out by a plate which is received in a pair of slots in forward and aft edges of the cut-out to clampingly overlie the bearing block. A lip on each of the bearing blocks is positioned and sized to abut a lateral surface of a respective grid member and a shoulder on the axle engages the bearing block for preventing movement laterally of the bearing, whereby the roller is restrained from movement axially. The aperture in the bearing block for receiving the axle has a center which is offset from the bearing block center to allow the roller height to be quickly and easily adjusted by removing the bearing block, rotating it, and re-inserting it.

Appl. No.:

8/034911

Inventors:

Ronald L. Plesh - Orchard Park NY

International Classification:

B65G 1300

US Classification:

193 35R

Abstract:

A method for cooling hot metal plates formed in a plate mill and inserts therefor. The metal plates are slid over a cooling bed plate transfer grid having a plurality of inserts supporting rollers wherein the metal plates are in contact with the rollers for decreased friction and reduced marring of the metal plates. The insert is clamped to the transfer grid so that it is easily and quickly removable and replaceable for cost effective plate cooling.

International Classification:

B65G 1300

US Classification:

193 35R

Abstract:

An insert to be removably and replaceably mounted in a pocket of a plate transfer grid for a cooling bed. The insert supports a roller to project above the members of the grid to engage plates for movement along the grid so as to reduce transfer grid wear and marring of the plates.

Appl. No.:

Inventors:

Ronald L. Plesh - Orchard Park NY

International Classification:

B65G 1312

US Classification:

193 35R

Abstract:

A cooling bed plate transfer grid insert which is height adjustable independently of its mounting to the grid. The insert has an outer frame which is clampable to the grid and an inner frame supporting a roller and which is clampable to the outer frame and height adjustable relative to the outer frame so that the mounting of the outer frame to the grid need not be disturbed when adjusting the height of the roller or when replacing the inner frame and roller assembly for repair of the insert. The inner frame is thus easily and inexpensively replaceable without the necessity of replacing the outer frame. The replaceable inner frame includes stationary bearings for the rotating roller shaft to provide improvement in wear life of perhaps about 200 per cent. Springs are provided to allow the roller to flexibly move downwardly under load of plates being moved thereover so that each of the rollers underlying a plate bears its share of the load, but the rollers are biased to the desired unloaded height. A ramp is provided on the inner frame for deflecting the plates being transferred onto the roller and thereby eliminating or reducing "catch points" which may cause thin plates to bend.
