Abstract
The utility model relates to a kind of bearing roller, is specifically related to a kind of tapered roller with resistance to shock.A kind of outer surface with the tapered roller of resistance to shock proposed is conical surface; The center of described tapered roller (1) has the axial hole (2) along axis processing; Tapered roller center there is axial hole (2) internal face be hyperboloid (3).The utility model when do not affect coordinate with bearing ring, retainer, add the elastic deformation amount of roller, when roller runs into stronger vibration or larger impulsive load, Absorbable rod part impact shock energy, reduce the impact vibrated bearing and main frame, thus improve the vibration resistance of bearing.
Description
Technical field
The utility model relates to a kind of bearing roller, is specifically related to a kind of tapered roller with resistance to shock.
Background technique
The tapered roller used in present tapered roller bearing is solid rigid body, is adapted at stability under loading, works without when judder; Due to the tapered roller poor flexibility in existing tapered roller bearing, lack the ability absorbing vibration, when running into strong impulsive load, dither can cause the nearly surface of tapered roller to produce plastic deformation, thus reduce the precision of bearing, affect bearing working performance, even can cause bearing failure.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model proposes a kind of tapered roller with resistance to shock.
The utility model adopts following technological scheme for completing above-mentioned purpose:
Have a tapered roller for resistance to shock, the outer surface of described tapered roller is conical surface; The center of described tapered roller has the axial hole along axis processing.
Tapered roller center there is axial hole internal face be hyperboloid.
A kind of tapered roller with resistance to shock that the utility model proposes, has the function identical with existing tapered roller and feature; Processing an internal surface at the center of tapered roller is bi-curved axial hole, when do not affect coordinate with bearing ring, retainer, add the elastic deformation amount of roller, when roller runs into stronger vibration or larger impulsive load, Absorbable rod part impact shock energy, reduce the impact vibrated bearing and main frame, thus improve the vibration resistance of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. tapered roller, 2. axial hole, 3. hyperboloid.
Embodiment
In conjunction with the drawings and Examples provided, the utility model is illustrated.
As shown in Figure 1, a kind of tapered roller with resistance to shock, the outer surface of described tapered roller 1 is conical surface; The center of described tapered roller 1 has the axial hole 2 along axis processing; Tapered roller center there is axial hole internal face be hyperboloid 3.
Claims (2)
1. have a tapered roller for resistance to shock, the outer surface of described tapered roller (1) is conical surface; It is characterized in that: the center of described tapered roller (1) has the axial hole (2) along axis processing.
2. a kind of tapered roller with resistance to shock according to claim 1, is characterized in that: tapered roller center there is axial hole (2) internal face be hyperboloid (3).
