Abstract
The utility model relates to a bearing, in particular to a conical plane thrust bearing with simple structure and good application effect, which comprises an outer ring, an inner ring and a conical roller between the inner ring and the outer ring, wherein the raceway surface on the outer ring for mounting conical roller is provided with a convex arc surface. The conical plane thrust bearing is characterized in that the raceway surface on the outer ring of the bearing is an arc surface, therefore, when bears high axial force, the force on the raceway surface is uniformly distributed, to reduce the effect of stress concentration and obtain good fatigue performance.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of circular cone plain thrust bearing.
Background technique
Bearing is widely used in the machinery rotation equipment, can be radial force according to the different bearings of use occasion, also can be axially loaded.When axially loaded is big, the roller of bearing, the roller surface of outer ring all will be received than galling, influence its anti-fatigue performance.The circular cone plain thrust bearing is exactly the bigger bearing type of axially loaded, and its roller surface is generally plane shape, and when receiving bigger bearing capacity, the stress concentration phenomenon is comparatively serious, has influenced the working life of whole bearing.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, circular cone plain thrust bearing that using effect is good.
The technological scheme that realizes the utility model purpose is:
A kind of circular cone plain thrust bearing has the tapered roller between outer ring, inner ring and the Internal and external cycle, and the lobed arc shaped surface of roller surface of tapered roller is installed on the above-mentioned outer ring.
The arc shaped surface of above-mentioned projection and the outside, outer ring intermediate location have curve bath.
Characteristics of the present utility model are that the roller surface of bearing outer ring is an arc shaped surface, and when bearing larger axis to power, the power effect that roller surface bears distributes comparatively even, have reduced the influence that stress is concentrated, and anti-fatigue performance is better; Because this novel arc shaped surface designs with the outside, outer ring transition zone curve bath, reduced the stress concentration phenomenon of this position under stressing conditions equally in addition, strong improvement the fatigue resistance of race way.
Description of drawings
Fig. 1 is the structural representation of the utility model outer ring part.
Fig. 2 is the enlarged diagram of A part among Fig. 1.
Embodiment
See shown in Fig. 1,2, the lobed arc shaped surface 1 of outer ring raceway face that this is novel, and transition zone is provided with curve bath 11 outside this arc shaped surface and the outer ring.The existence of above-mentioned arc shaped surface, power distributes comparatively evenly when making it bear axial force, has reduced the influence that stress is concentrated, and the existence of curve bath has reduced the stress concentration of roller surface and outer ring intermediate location equally, strengthen its anti-fatigue performance, prolonged the working life of bearing.This novel bearing relatively is applicable to the occasion that rotating speed is higher, axially locating is accurate, axial impact force is bigger.
Claims (2)
1, a kind of circular cone plain thrust bearing has the tapered roller between outer ring, inner ring and the Internal and external cycle, it is characterized in that: the lobed arc shaped surface of roller surface (1) that tapered roller is installed on the above-mentioned outer ring.
2, according to the described circular cone plain thrust bearing of claim 1, it is characterized in that: the arc shaped surface of above-mentioned projection and the outside, outer ring intermediate location have curve bath (11).
