Embodiment Construction

[0018] refer to figure 1 , which shows a mill coupling comprising a mandrel 10 having a motor or driven end 12 at which drive rotation is applied to the shaft; and a roll end 16 for coupling to the roll. The roller end of the shaft drives a hub gear which in turn interacts with and drives a coupling gear. In the illustrated embodiment, the driven end of the shaft includes a U-joint assembly 14 to be coupled to a drive. However, in a typical spindle application, the driven end of the shaft will include a hub gearing similar to the roller end. In this regard, and by way of example only, refer to figure 2 , which shows a complete rolling mill drive in which the oil recirculation system and seals that are the subject of the present application can be implemented. In particular, a rolling mill drive train 20 , eg for rolling metal such as steel, is shown. Mill drive train 20 includes motor 22 operatively connected to work rolls 24 and 26 through a drive train power transmissi...

Abstract

A gear spindle includes a shaft having a first gear cavity at a first end, an oil delivery path for delivering oil to the first gear cavity and an oil return path for carrying oil away from the first gear cavity. A first seal assembly is associated with the first end of the shaft for limiting leakage of oil from the first gear cavity, the first seal assembly including a sealing interface having one side in fluid communication with the first gear cavity and an opposite side in fluid communication with a fluid delivery path. The fluid delivery path may be connected to a source of pressurized air for reducing pressure differential across the sealing interface.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Application No. 61 / 160864, ​​filed March 17, 2009. technical field [0003] The present application relates generally to rolling mill drives, and more particularly to recirculating oil systems for shafts of rolling mill drives. Background technique [0004] Oil recirculation systems have been used in the past in conjunction with mill drives. One problem associated with such devices is that of oil leakage. Accordingly, it would be desirable to provide a drive that limits or prevents such oil leakage. Contents of the invention [0005] In one aspect, a gear spindle includes: a shaft having a first gear cavity at a first end; an oil delivery path for delivering oil to the first gear cavity; and an oil return path, the oil return path is used to carry oil away from the first gear cavity. A first seal assembly is associated with the first end of the shaft for limiting oil leakage from the ...
