Abstract
The utility model discloses a long-lifetime main cone bearing for a commercial automobile belonging to the technical field of rolling bearings and mainly solving the technical problems that a large flange of a steel inner ring, which is made of ordinary material, of a conical roller bearing for a conventional automobile main cone is easily broken, while the cost is too high if the whole set is made of high-strength material. The long-lifetime main cone bearing for the commercial automobile is mainly characterized by comprising a conical roller bearing consisting of an outer ring, an inner ring with a large flange, a roller and a retaining rack, wherein only the inner ring is made of carburized steel; and the depth of an effective carburizing layer of the carburized steel of the inner ring is 0.8-1.3 mm. The long-lifetime main cone bearing for the commercial automobile has the characteristics of low manufacturing cost and long service life and is mainly applicable to supporting a driving bevel gear of automobile axles.
Description
Technical field
The utility model belongs to technical field of rolling bearings.Be specifically related to a kind of commercial car main cone and use tapered roller bearing, be used for the automotive axle drive bevel gear and support.
Background technique
Commercial car main cone bearing in use can receive very strong axial impact, and promptly bearing is in operation process; Master bevel gear can have very big axial force to the bearing inner sleeve large-flange, if interior cover rib insufficient strength, in use; Be easy to crushed, thereby reduce bearing working life.
At present,, two kinds of ways are arranged usually: 1, strengthen inner ring large-flange thickness, will certainly take like this that roller is former to have living space, reduce roller diameter at butt end and length, thereby reduce the specified bearing capacity of bearing in order to strengthen rib intensity; 2, bearing is selected non-Bearing Steel (GCr15) material for use, and promptly a complete set of bearing is selected the steel for carburizing material of toughness height, surface abrasion resistance for use, and this material price can be high more a lot of than Bearing Steel, increase the bearing manufacture cost greatly.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned deficiency, provides a kind of low cost, long-life automobile main cone to use tapered roller bearing.
The technical solution of the utility model is: a kind of commercial car long lifetime main cone bearing; Comprise the tapered roller bearing that constitutes of inner ring, roller and retainer by outer ring, band large-flange; It is characterized in that: only inner ring is the inner ring of being processed by steel for carburizing, and the effective case depth of inner ring steel for carburizing is 0.8～1.3mm.
The outer ring of outer ring described in the technical solution of the utility model for processing by the plain bearing steel.
The roller of roller described in the technical solution of the utility model for processing by the plain bearing steel.
The retainer of retainer described in the technical solution of the utility model for processing by general steel plate.
The effective carburized case of inner ring steel for carburizing described in the technical solution of the utility model is the carburized case that is made up of G20CrMo (A), G20CrNiMo (A), G20CrNi2Mo (A), G20Cr2Ni4 (A), G10Cr Ni3Mo (A), G20Cr2Mn2Mo (A) or its combination ingredient.
The utlity model has following good effect:
Because inner ring selects steel for carburizing for use, inner ring large-flange intensity is enhanced, thereby need not to increase inner ring large-flange thickness, also can satisfy the load usage requirement, can improve bearing working life.Since in a complete set of bearing only inner ring select the steel for carburizing material for use, and other parts are selected the plain bearing steel for use, thereby can greatly reduce the manufacture cost of bearing.
The utlity model has the characteristics of low cost of manufacture, long service life.The utility model is mainly used in the automotive axle drive bevel gear and supports.
Description of drawings
Fig. 1 is the structural representation of the utility model and automobile main cone part.
Fig. 2 is the effective case depth schematic representation of the utility model inner ring.
Embodiment
Like Fig. 1, shown in Figure 2.Commercial car main cone 3 is provided with main cone fore bearing 2 and main cone rear bearing 1.The utility model is main cone fore bearing 2 or main cone rear bearing 1, is to use tapered roller bearing by the automobile main cone that the inner ring 6 of an outer ring 4, a band large-flange 7 and the roller 5 between outer ring 4 and the inner ring 6 and retainer 8 constitute.Outer ring 4, outer ring, the roller of roller 5 for processing by the plain bearing steel, the retainer of retainer 8 for being processed by general steel plate is identical with existing technology.Only inner ring 6 is the inner ring of being processed by steel for carburizing; And the effective case depth d of inner ring 6 steel for carburizing is 0.8～1.3mm, and the effective carburized case of inner ring 6 steel for carburizing is the carburized case that is made up of G20CrMo (A), G20CrNiMo (A), G20CrNi2Mo (A), G20Cr2Ni4 (A), G10Cr Ni3Mo (A), G20Cr2Mn2Mo (A) or its combination ingredient.
Claims (5)
