Abstract
The utility model provides a cantilever shaft support device which comprises a shaft, a bearing support, a bearing cover, at least four rolling bearings, two sleeves, two seal rings and two compression rings, wherein the rolling bearings are positioned inside the bearing support, the inner rings of the rolling bearings are closely fixed to the shaft, the outer rings of the rolling bearings are closely fixed to the bearing support, two radial through-holes are formed on the bearing support and positioned on the same plane and perpendicular to each other, the two radial through-holes are positioned at the end part of the rolling bearings and communicated with the inner cavities of the rolling bearings, a first gap is formed between the first sleeve and the end surfaces of the rolling bearings, and a second gap is formed between the bearing cover and the end surfaces of the rolling bearings. Since the lubricating oil enters the rolling bearings through the two through-holes on the bearing support, the cantilever shaft support device maintains the advantages of the present support device, has strong load-carrying ability and less frictional loss, ensures that the lubrication is convenient and rapid, and achieves the continuous lubrication.
Description
Technical field
The utility model 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, the purpose of this utility model provides a kind of not only lubricated very convenient, and bears the cantilevered axle support device that the transient load ability is also strengthened greatly.
Cantilevered axle support device of the present utility model 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 utility model, 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 utility model 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.
