Abstract
The utility model discloses a new tapered roller which comprises a tapered body; and the new tapered roller is characterized in that the surrounding edge of the upper end part of the tapered body is formed into a circular arc part, and the radian of the circular arc part is 40-160 degrees; and the surrounding edge of the lower end part of the tapered body is formed into a circular arc part, and the radian of the circular arc part is 50-150 degrees. According to the utility model, the service life is prolonged, and the safety performance of car traveling is greatly improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially relates to a kind of new tapered roller.
Background technique
Tapered roller bearing belongs to the divergence type bearing, the inside and outside circle of bearing all has cone row raceway, can bear radial load and single direction axial load, when bearing bears radial load, will produce an axial thrust load, so come in addition balance when needing another can bear in the other direction bearing of axial force.
all must be equipped with tapered roller in tapered roller bearing and roller wheel hub, the special load that the parts that form bear in transmission, bear simultaneously axial force and radial force, the life-span of constituent elements and quality, tapered roller is one of crucial part, there is simultaneously weak deficiency, except the material of tapered roller, also have the rolling surface of roller work in-process and the cusped edge of chamfering boundary, the shape of generatrix of rolling surface, shape of roller working standard end face etc., the existence of these problems has a strong impact on working life, especially use and have potential life safety in automotive hub, therefore must improve.
As from the foregoing, the problem that exists in present product is badly in need of solving.
In view of this, the inventor has done deep research to this, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of new tapered roller, can solve above-mentioned the deficiencies in the prior art part, increase the service life, greatly improve the Safety performance of automobile running, this case produces thus.
The model utility content
The purpose of this utility model is to provide a kind of new tapered roller, can solve above-mentioned the deficiencies in the prior art part, increases the service life, and greatly improves the Safety performance of automobile running.
To achieve these goals, the technical solution of the utility model is as follows:
New tapered roller, comprise conical body, it is characterized in that: the edge, upper end portion of described conical body forms circular arc part, and the radian of described circular arc part is the 40-160 degree, the edge, underpart of described conical body forms circular arc part, and the radian of described circular arc part is the 50-150 degree.
Further, the outer surface of described conical body is cambered surface, and the radian of described cambered surface is the 130-75 degree.
Further, described cambered surface evagination 0.1-1mm.
The beneficial effects of the utility model: the edge, upper end portion of the utility model conical body forms circular arc part, the edge, underpart of described conical body forms circular arc part, the outer surface of described conical body is sphere, such setting, make and reach best coordinating between tapered roller and wheel hub, make overall structure greatly be simplified, and increase meeting also of can bear, guarantee the driving safety of vehicle.
The stress distribution that the rolling surface of whole tapered roller of while bears is even, and ensemble average is stressed, so just greatly increases the service life, and reduces the probability of concentrated wear.
The beneficial effects of the utility model: the utility model increases the service life, and greatly improves the Safety performance of automobile running.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model relates to a kind of new tapered roller, comprise conical body 1, it is characterized in that: 2 edges, upper end portion of described conical body 1 form circular arc part 4, the radian of described circular arc part 4 is the 40-160 degree, 3 edges, underpart of described conical body 1 form circular arc part 4, and the radian of described circular arc part 4 is the 50-150 degree.
Further arrange, the outer surface of described conical body 1 is cambered surface 5, and the radian of described cambered surface 5 is the 130-75 degree.
Described cambered surface 5 evagination 0.1-1mm further are set.
The above is only an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
