Abstract
The utility model belongs to the technical field of mechanical manufacture and is a bearing used for the steering main pin of the front wheel of a truck. The utility model adopts a thrust column roller bearing under the premise of not altering the installation dimension and the bearing capacity of the bearing to meet a host machine; the dimension of the internal structure of the bearing is altered and the wall thickness of a ferrule is reduced; the diameter of the roller is increased; the quantity of the rollers is reduced. Thereby, the minimum width of the lintel of a cage is widened, and compared with the original thrust circular cone roller bearing, the utility model reduces the internal friction of the bearing, enhances the rotating flexibility of the host machine and extends the service life of the bearing by a plurality of times.
Description
The utility model belongs to machine-building spare part in common use field of bearings, is used for the positioning support of truck foresteerage gear stub, mainly bears axial load.
Present domestic truck such as Jiefang brand, Dongfeng brand and its front-wheel steer stub of Shanghai traffic board truck generally use 129908 or 229908 tapered roller thrust bearings.(the bearing size structure of these two kinds of models is basic identical) these bearing structure characteristics are that tapered roller is filled in inside, no retainer, thrusting plate raceway and roller have cone angle up and down, difficulty of processing is big, the cone angle machining error influences the stress of bearing inside, therefore the bearing internal friction is big, rotates very flexible, and bearing is short working life.External truck major part also adopts tapered roller thrust bearing, but because process equipment can guarantee the bearing parts quality of processing with technology, and the inner stressed even and wear problem of bearing does not seem very outstanding.The also useful cylindrical roller thrust bearing of domestic automobile maintenance department replaces tapered roller thrust bearing to be applied on the vehicle front pivot stud, but the internal structure of bearing is unreasonable, and it is low that retainer is crossed beam strength, influenced working life.
The purpose of this utility model is by to bearing internal structure and size-modify, to reduce internal friction not changing under the prerequisite of main frame to the requirement of bearing external dimension, improves lubricating condition, improves bearing load carrying capacity, rotates flexibility and working life.
Be the employing cylindrical roller thrust bearing that achieves the above object, compare with 229908 cylindrical roller thrust bearings that auto repair department adopts that lasso thickness reduces 1mm, roller diameter increases 2mm, and roller quantity reduces 4, crosses beam width thereby increased retainer.
This bearing 409908K is of a size of: internal diameter * external diameter * wide=φ 66.7 * φ 38.5 * 17mm
3, thrusting plate (blowout patche, seat ring) thickness is 4.5mm, short columnar roller is of a size of: diameter * length=φ 8 * 8mm
2, roller quantity is 14.The axial carrying capacity dynamic load rating is 57.9KN, and basic static capacity (BSC) rating is 74.7KN.
The utility model bearing 409908KN and known bearing 229908 tapered roller thrust bearings and cylindrical roller thrust bearing are compared as follows table:
Accompanying drawing is the utility model bearing 409908K sectional view.By blowout patche 1, seat ring 2, retainer 3, cylindrical roller 4 and case 5 are formed, and each size is seen in the accompanying drawing.
The utility model bearing 409908K is on probation and No. 2 Automobile Factory's test car installation operation by some auto repair units, respond well, the steering wheel moment of rotation evenly, flexibly, bearing has reached 3-8 kilometer (still in use) working life, improves several times working life than former tapered roller thrust bearing.
Claims (3)
1, the truck pivot stud comprises inner ring, outer ring, retainer, case each one and a row roller with cylindrical roller thrust bearing, it is characterized in that: reduce blowout patche, seat ring wall thickness, increase roller diameter, reduce roller quantity, thereby increased the minimum beam width of crossing of retainer.
2,, it is characterized in that inside and outside circle wall thickness reduces to 4.5mm according to the described bearing of claim 1.
3, according to claim 1,2 described bearings, it is characterized in that roller is of a size of: diameter * length=φ 8 * 8mm
2, roller quantity reduces to 14.
