Abstract
The utility model provides a taper bearing made of a series of combined materials. The taper bearing belongs to the technical field of a rolling bearing. The taper bearing mainly settles the following problems in the taper roller bearing for automotive wheel hub, gearbox and driving axle main cone: breakage of an inner-ring large rib and early-period failure of raceway if common-material bearing steel is adopted, and overhigh cost if cemented steel material is adopted for the whole set of taper roller bearing. The taper bearing provided by the utility model is mainly characterized in that: the taper bearing comprises a taper roller bearing which is used for an automotive main cone and is composed of an outer ring, an inner ring with a large rib, and a roller and a holding frame between the outer ring and the inner ring. Only the inner ring is made of cemented steel. Furthermore the thickness of the effective carburized layer of the cemented steel of the inner layer is 0.8-2.3mm. The taper bearing made of a series of combined materials has the characteristics of low fabricating cost and long service life. The taper bearing is mainly used for supporting a plurality of components such as automotive wheel hub, gearbox and driving axle main cone.
Description
Technical field
The utility model belongs to technical field of rolling bearings, is specifically related to a kind of commercial car tapered roller bearing, is used for series such as automotive hub, gearbox, ransaxle main cone and supports.
Background technique
Commercial car (particularly engineering truck) wheel hub, gearbox, ransaxle main cone conical bearing in use are subjected to very strong impulsive load through regular meeting.At present, American TI MKEN bearing material is still based on steel for carburizing, and main purpose is exactly protecting against shock load, improves bearing life.The material of China's rolling bearing is based on Bearing Steel, and the wear resistance of bearing is good but protecting against shock is poor.
A complete set of bearing is selected for use the steel for carburizing material of toughness height, surface abrasion resistance can increase the material of bearing greatly and is improved manufacture cost greatly.From the failure mode of the tapered roller bearing of bearing steel material processing, the tired and early damage of inner ring is the thing of big probability.How to reduce cost and can improve the reliability of conical bearing and life-span people are long-term just and consider and urgent problem.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned deficiency, and a kind of low cost is provided, the automotive hub of long lifetime and high reliability, gearbox, ransaxle main cone series conical bearing.
Technical solution of the present utility model is: a kind of conical bearing of series of combination material, be used for automotive hub, gearbox, the supporting of ransaxle main cone, comprise the tapered roller bearing that is constituted by an outer ring, band inner ring of large-flange and the roller between outer ring and the inner ring and retainer, it is characterized in that: only described inner ring is the inner ring of being made by steel for carburizing, and the effective case depth of inner ring steel for carburizing is 0.8～2.3mm.
The effective carburized case of inner ring steel for carburizing described in the technical solution of the present utility model is the carburized case that is made of G20CrMo (A), G20CrNiMo (A), G20CrNi2Mo (A), G20Cr2Ni4 (A), G10Cr Ni3Mo (A), G20Cr2Mn2Mo (A) or its combination ingredient.
Outer ring described in the technical solution of the present utility model is the outer ring by GCr15-the GB/T18254 Bearing Steel is made.
Roller described in the technical solution of the present utility model is the roller by GCr15-the GB/T18254 Bearing Steel is made.
Retainer described in the technical solution of the present utility model is for by 10 or retainer that 08-II-P-the GB/T13237 steel plate is made.
Outer ring outside dimension described in the technical solution of the present utility model is φ 50 ~ 250mm.
The utlity model has following good effect:
Because inner ring is selected steel for carburizing for use, inner ring large-flange, raceway impact strength is enhanced, thereby need not to increase inner ring large-flange thickness, also can satisfy the load usage requirement, can improve bearing working life and reliability.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 low cost of manufacture, long service life and high reliability features.The utility model is mainly used in commercial car (particularly engineering truck) wheel hub, gearbox, the supporting of ransaxle main cone series.
Description of drawings
Fig. 1 is the effective case depth schematic representation of the utility model inner ring.
Embodiment
It is the automobile main cone tapered roller bearing of being with the inner ring 2 of large-flange 3 and the roller 4 between outer ring 1 and the inner ring 2 and retainer 7 to constitute by an outer ring 1, one with bearing that the utility model is automotive hub, gearbox, ransaxle main cone series.Outer ring 1, outer ring, the roller of roller 4 for being made by the plain bearing steel, the retainer of retainer 7 for being made by general steel plate, the plain bearing steel is GCr15-GB/T18254 Bearing Steel, and general steel plate is steel plate 10 or 08-II-P-GB/T13237, and is same as the prior art.Only inner ring 2 is the inner ring of being made by steel for carburizing, and the effective case depth D of inner ring 2 steel for carburizing is 0.8～2.3mm, and the effective carburized case of inner ring 2 steel for carburizing is the carburized case that is made of G20CrMo (A), G20CrNiMo (A), G20CrNi2Mo (A), G20Cr2Ni4 (A), G10Cr Ni3Mo (A), G20Cr2Mn2Mo (A) or its combination ingredient.Just become the steel for carburizing with carburized case after the carburizing of steel for carburizing process heat treatment process.The Carburization Treatment technical specifications of steel for carburizing are carried out by the JB/T8881 requirement, carburizing heat treatment process: temperature 880 degree ~ 930 degree, carburizing time is by the carburizing efficient concrete decision of depth of penetration requirement and casehardening furnace.Outer ring 1 outside dimension is φ 50 ~ 250mm.
