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
The present invention relates to a kind of cantilevered axle support device of bearing load.
Background technique
The cantilevered axle support device is extensive use of in a plurality of fields such as machinery, metallurgy, water power water conservancy, mining machinery, railway, building machinery, iron and steel, packing, petrochemical industry, instrument and apparatus, precision type instrument.At present the cantilevered axle support device that uses mainly comprise the bearing support that is used to support, as the axle and the bearing of cantilever, always need during bearing lubrication bearing is pulled down lubricated, inconvenience very.And most bearing load carrying capacity all is very limited, has the place of temporary impact load for some, and the life-span of bearing often has a greatly reduced quality.
Summary of the invention
In order to overcome the inconvenience of bearing lubrication, and the defective of carrying transient load scarce capacity, it is a kind of not only lubricated very convenient to the purpose of this invention is to provide, and bears the cantilevered axle support device that the transient load ability is also strengthened greatly.
Cantilevered axle support device of the present invention comprises axle, bearing support, bearing cap, at least four rolling bearings, two sleeves, two seal rings and two pressure rings.Rolling bearing is positioned at bearing support, the inner ring of rolling bearing is fastening with axle, outer ring and bearing support are fastening, have two on the bearing support and be in same plane, orthogonal radial direction through hole, two radial direction through hole are positioned at the end of rolling bearing, and be communicated with the inner chamber of rolling bearing, side at bearing support is equipped with first sleeve, the inner ring of first sleeve is fastening with axle, outer ring and bearing support relatively rotate, be provided with first seal ring between first sleeve and the bearing support, first seal ring is by the first pressure ring axial compression, and is gapped at the end face of first sleeve and rolling bearing; The opposite side of bearing support is equipped with second sleeve, the inner ring of second sleeve is fastening with axle, and outer ring and bearing cap relatively rotate, and are provided with second seal ring between second sleeve and the bearing cap, second seal ring is by the second pressure ring axial compression, and is gapped at the end face of bearing cap and rolling bearing.
Cantilevered axle support device of the present invention, lubricant oil enters rolling bearing by two through holes on the bearing support, even also can be lubricated under the working state like this, the gap at rolling bearing two ends simultaneously can guarantee the perfect lubrication of ball bearing outer.Use at least four rolling bearings that bearing capacity is strengthened greatly, make bearing support bear temporary impact load realization buffering to a certain degree simultaneously, strengthened the bearing capacity of rolling bearing greatly.
The present invention is simple in structure, and is lubricated convenient and swift, can realize continuous lubrication; Axial carrying capacity strengthens greatly, and also can increase greatly the fatigue life of bearing; During one-sided support, can bear bigger radial force, good stability.
