Abstract

The invention relates to a cantilever shaft supporting device which comprises a shaft, a bearing seat, a bearing cap, at least four rolling bearings, two sleeve barrels, two sealing rings and two compression rings, wherein the rolling bearings are positioned in the bearing seat; the inner ring of each rolling bearing is tightly fixed with the shaft, and the outer ring of each rolling bearing is tightly fixed with the bearing seat; two orthogonal radial through holes which are positioned in the same plane are formed on the bearing seat; the two radial through holes are positioned at the end part of each rolling bearing and are communicated with the inner cavity of each rolling bearing; a gap is formed between the first sleeve barrel and the end surface of each rolling bearing; and a gap is formed between the bearing cap and the end surface of each rolling bearing. In the cantilever shaft supporting device, lubricating oil enters the rolling bearings through the two through holes on the bearing seat; and the cantilever shaft supporting device not only has the advantages of the traditional supporting device but also has strong bearing capacity, small friction loss and convenient and quick lubrication, and can realize continuous lubrication.

Description

technical field [0001] The invention relates to a load-carrying cantilever shaft supporting device. Background technique [0002] Cantilever shaft support devices are widely used in many fields such as mechanical equipment, metallurgy, hydropower and water conservancy, mining machinery, railways, construction machinery, steel, packaging, petrochemical, instrumentation, and precision instruments. The currently used cantilever shaft supporting device mainly includes a bearing seat for support, a cantilever shaft and a bearing. When lubricating the bearing, it is always necessary to remove the bearing for lubrication, which is very inconvenient. Moreover, most of the bearing capacity is very limited, and for some places where there are instantaneous impact loads, the service life of the bearings is often greatly reduced. Contents of the invention [0003] In order to overcome the inconvenience of bearing lubrication and the shortcoming of insufficient instantaneous load carr...
