Abstract
The utility model discloses a thrust taper roller bearing used for the heavy-duty automobile front hanging frame angle steering burl, a seat ring and an axis ring support a list of taper rollers, the outer of the seat ring and the axis ring are tightly fixed with an outer cover, the side of the taper roller extends towards to the center axis direction of the bearing and then a cone angle Alpha with 18 degrees 45 minute is formed, the seat ring and the axis ring matching with the taper roller have the same cone angle Alpha. The utility model can simultaneously bear axial loads and radial loads, the carrying capacity reaches 5560 Ib, the carrying capacity and the service life of the bearing are improved, the utility model has better rotating flexibility and radial positioning function.
Description
Affiliated technical field
The utility model belongs to the automobile field of bearings, is specially adapted to the thrust stub bearing that heavy-load automobile front suspension angle knuckle is used.
Background technique
At present, the automobile front suspension angle turns to the thrust stub bearing of usefulness, the anterior weight of bearing body, front-wheel can be turned to, and its structure is to fill roller two lasso inside, and the roller of the inside of bearing does not have angle, can only bear thrust load, load only is 1750Ib, and this structure makes the stressed axial direction that concentrates on of bearing inside, has influenced the working life of bearing.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, and under the situation that does not change the Bearing Installation size, the axially loaded decomposition with bearing obtains the better tapered roller thrust bearing of a kind of performance, can substitute present thrust stub bearing fully.
The technological scheme that the utility model adopted is: seat ring and blowout patche are supporting a row tapered roller, fastening overcoat outside seat ring and blowout patche, the side of described tapered roller to the bearing centre axle direction extend the back form a cone angle be 18 ° 45 ', the seat ring and the blowout patche that cooperate with tapered roller also have identical cone angle.
After the utility model adopted such scheme, bearing can bear thrust load and radial load simultaneously, and bearing capacity reaches 5560Ib, has improved the bearing capacity and the working life of bearing, has flexibility of revolution and radial location function preferably.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Embodiment
As shown in Figure 1, the seat ring 1 of bearing and blowout patche 2 are supporting a row tapered roller 3, the outer wall of present Fig. 1 and blowout patche 2 fastening an overcoat 4, compare with thrust stub bearing commonly used at present, the structure of tapered roller 3 has been done improvement, be designed to the tapered roller of big cone angle, made the side of described tapered roller extend back formation one cone angle to the bearing centre axle direction, cone angle be 18 ° 45 ', simultaneously also be designed to have identical cone angle with seat ring 1 and the blowout patche 2 that tapered roller 3 cooperates.
In addition, general bearing uses the GCr15 high-carbon-chromium bearing steel, hardness is 60-65HRC, has higher fatigue strength and wear resistance, and the utility model adopts the G20CrNiMo carburizing bearing steel, hardness is 58-64HRC, centre hardness is 35-45HRC, and case depth 1.02-1.05mm, core structure have high-strength tenacity again, the load that can withstand shocks has high wear resistance, high antifatigue.So the impulsive load that the utility model can bear is bigger than general thrust stub bearing, and flexibility of revolution is strong, and can improve more than 2 times working life.
Installation of the present utility model is consistent with common thrust stub bearing with processing method.
Claims (3)
1, a kind of tapered roller thrust bearing, seat ring (1) and blowout patche (2) are supporting a row tapered roller (3), fastening an overcoat (4) outside seat ring (1) and blowout patche (2), it is characterized in that: the side of described tapered roller (3) is extended the back to the bearing centre axle direction and is formed a cone angle, and the seat ring (1) and the blowout patche (2) that cooperate with tapered roller (3) also have identical cone angle.
2, a kind of thrust roller bearing according to claim 1 is characterized in that: described cone angle be 18 ° 45 '.
