Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of double-row conical bearing of being convenient to installation.
For achieving the above object, the utility model provides following technological scheme: a kind of double-row conical bearing, comprise the outer ring, retainer and the inner ring that set gradually, described retainer is provided with the tapered roller of some quantity, described outer ring is provided with positioning step, relative positioning step one end, described outer ring is provided with the supporting post being wholely set with outer ring, and described supporting post is provided with outside thread.
By adopting technique scheme, on outer ring, be provided with positioning step, surface, the outstanding outer ring of this positioning step, contribute to operator bearing to be fixed on the parts that match when double-row conical bearing is installed, play the effect of location double-row conical bearing, improve the degree of accuracy that double-row conical bearing is installed; And on outer ring, be provided with externally threaded supporting post, can by the supporting post on rotation double-row conical bearing, to the parts that match, fix double-row conical bearing when mounted, reduce the operation easier that double-row conical bearing is installed.
The utility model is further set to: on the surface of contact of described retainer and described tapered roller, be provided with wearing layer.
By adopting technique scheme, on the surface of contact of retainer and tapered roller, be provided with wearing layer, when double-row conical bearing is worn or destroys owing to being subject to the surface of contact that frictional loss causes retainer and tapered roller in when work, wearing layer the degree of wear that can slow down between retainer and tapered roller is set, reduce frictional loss simultaneously, extended the working life of double-row conical bearing.
The utility model is further set to: described wearing layer is carburized case, nitriding layer or electrodeposited coating.
By adopting technique scheme, on the surface of contact of retainer and tapered roller, be provided with wearing layer, wearing layer can be carburized case, nitriding layer or electrodeposited coating, can slow down the degree of wear between retainer and tapered roller, reduce frictional loss, extended the working life of double-row conical bearing.
The utility model is further set to: the surface uniform of described outer ring, inner ring and tapered roller is coated with oil lamella.
By adopting on the surface of technique scheme ， outer ring, inner ring and tapered roller, be evenly coated with oil lamella, oil lamella is to take bearing oil to make as raw material adopts titanium nitride physical vapor deposition surface coating technology, has the effect of lubricated double-row conical bearing; And bearing oil is that employing refined mineral oil is base oil, add appropriate antioxygen, the multiple additives such as antirust, wear-resistant modulation to form, adopt oil lamella to reduce the friction factor between outer ring, inner ring and tapered roller, reduce frictional loss, and improved the rustless property of double-row conical bearing.
The utlity model has following advantage: by be provided with positioning step on outer ring, while contributing to install, position, improve the degree of accuracy that double-row conical bearing is installed; On outer ring, be provided with externally threaded supporting post, can be used for fixing when mounted double-row conical bearing, reduce the operation easier of installing.
