Abstract
The invention discloses a guide cylindrical bearing of a hybrid power main reducer, and belongs to the technical field of rolling bearings. The bearing mainly solves the problems that according to a guide cylindrical bearing of an existing hybrid power main reducer, an inner ring is prone to fatigue, and the inner ring is prone to being damaged early. The guide cylindrical bearing is mainly characterized by comprising a full-cylindrical roller bearing composed of an outer ring, an inner ring, a blocking piece and a roller between the outer ring and the inner ring, the s blocking piece and the roller are made of bearing steel materials, only the inner ring or the inner ring and the outer ring are made of carburizing steel materials, the effective carburized layer depth of the inner ring or the inner ring and the outer ring is 0.8 mm to 2.3 mm, and the center hardness HRC is 30 to 45. The guide cylindrical bearing has the advantages of being low in manufacturing cost, long in service life and high in reliability, and is mainly used for main cone guide series bearing of a hybrid power commercial vehicle main reducing gear.
Description
Technical field
The invention belongs to technical field of rolling bearings, be specifically related to a kind of mixed powered car roller bearing, support for main reducing gear of drive axle main cone guiding series.
Background technique
Mixed mixed power commercial car main reducing gear guide cylinder bearing, be subject to continually in the course of the work very strong impulsive load, the bearing of conventional bearing steel material manufacture can not meet the requirement (as Fig. 2) of practical application, life-span can only reach 1 ~ 20,000 kilometer, with the above life requirements of 50,000 kilometers of the main frame clients distance that differs greatly.
The material of China's rolling bearing is taking Bearing Steel as main, and the wear resistance of bearing is good but protecting against shock is poor.Steel for carburizing material heat treatment rear surface hard-core portion is soft, can effectively prevent impulsive load, improves bearing life.
If a complete set of Selection of Bearings toughness is high, the steel for carburizing material of surface abrasion resistance can significantly increase bearing material and manufacture cost.The failure mode of mixed powered car owner's retarder guide cylinder bearing of processing from bearing steel material, inner ring fatigue and early damage are principal modes.At present, only have imported bearing just to meet customer requirement.How to reduce costs and can improve reliability and the life-span engineers problem in urgent need to solve just of guide cylinder bearing.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, provides a kind of cost performance good guide cylinder bearing, improves bearing life and reliability, replace imported.
Technical solution of the present invention is: a kind of mixed power main reducing gear guide cylinder bearing, support for mixed powered car main reducing gear of drive axle main cone guiding series, comprise the full roller bearing being formed by the roller between an outer ring, inner ring, catch and an outer ring and inner ring, outer ring, catch, roller that outer ring, catch, roller are On The Quality of Bearing Steels, it is characterized in that: only described inner ring is the inner ring by steel for carburizing material, and the effective case depth of inner ring steel for carburizing is 0.8～2.3mm, centre hardness is HRC30 ~ 45.
Technical solution of the present invention can also be: a kind of mixed power main reducing gear guide cylinder bearing, support for mixed powered car main reducing gear of drive axle main cone guiding series, comprise the full roller bearing being formed by the roller between an outer ring, inner ring, catch and an outer ring and inner ring, catch, roller that catch, roller are On The Quality of Bearing Steels, it is characterized in that: only described inner ring, outer ring are inner ring, the outer ring of steel for carburizing material, and inner ring, the effective case depth of outer ring steel for carburizing are 0.8～2.3mm, and centre hardness is HRC30 ~ 45.
The effective carburized case of steel for carburizing described in technical solution of the present invention is that grade of steel is the effective carburized case of steel for carburizing of G20CrMo (A), G20CrNiMo (A), G20CrNi2Mo (A), G20Cr2Ni4 (A), G10Cr Ni3Mo (A) or G20Cr2Mn2Mo (A).
Cylindrical bearing described in technical solution of the present invention or outer ring outside dimension are φ 50 ~ 200mm.
The present invention has following good effect:
Because inner ring is selected steel for carburizing, or inside and outside circle all selects steel for carburizing, thereby raceway impact strength is enhanced, and adds rational centre hardness, and general HRC30 ~ 45, can improve guide cylinder roller bearing working life and reliability.Due in a complete set of bearing only inner ring or only inside and outside circle select steel for carburizing material, and other parts are selected plain bearing steel, thereby have reduced the manufacture cost of bearing.
The present invention has the advantages that low cost of manufacture, long service life and reliability are high.The present invention is mainly used in the supporting of mixed powered car owner's retarder main cone guiding series.
