The present disclosure relates to a sealing arrangement for a bearing, wherein the sealing arrangement includes an O-ring for preventing the leakage of a lubricating fluid from an interface of at least one rotating element of the bearing and a secondary rotating body.
BACKGROUND
A bearing is a machine element that constrains the relative motion and reduces friction between the moving parts so as to allow the desired motion. Generally, the bearing consists of an inner race, an outer race, a roller, and a cage. During the operation of the bearing, either one of the inner race or outer race rotates while other remains stationary. The inner race of the bearing is in contact with a shaft, and there are chances of the lubricating fluids emanating from an interface of the inner race and the shaft. Due to this, there are chances of mixing of the lubricating fluid with other lubricating fluid in surrounding of the bearing, resulting in subsequent failure of a lubrication system, and the bearing of a vehicle.
Figure 1 illustrates a schematic view of a conventional bearing 100, the conventional bearing 100 comprises
• an inner race 10;
• an outer race 16;
• at least one rolling element 12; and
• a cage 14 is the housing of the rolling element 12.
Further, the conventional bearing 100 is provided with a chamfered inner edge ‘B’ that facilitates in receiving the shaft. Due to the leakage of lubricating fluids from in and around an area between an interface of the inner race 10 of the conventional bearing 100 and the shaft, mixing of the lubricating fluid emanating from the interface with the lubricating fluid present in surrounding of the conventional bearing 100 may occur resulting in reduction in performance and service life of the conventional bearing 100 and hence of the vehicles.
Hence, there is a need to provide an arrangement inside the bearing so as to eliminate the above mentioned drawbacks.

DETAILED DESCRIPTION
A sealing arrangement of a bearing of the present disclosure will now be described with reference to the embodiments which do not limit the scope and ambit of the disclosure.
The embodiments herein, the various features and the advantageous details thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known components and processing techniques are omitted so that there is no unnecessarily confusion about the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
The description hereinafter, of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.
Figure 2 illustrates a sealing arrangement of a bearing 200 in accordance with the present disclosure. The bearing 200 comprises
• an inner race 24;
• at least one rolling element 26;
• a cage 28 is the housing of the rolling element 26; and
• an outer race 30.
According to the present disclosure, the sealing arrangement for configuring seal between an interface of at least one rotating element (inner race 24 and/or outer race 30) of a bearing 200 and a secondary rotating body comprises
• an inwardly extending groove 22 configured on the inner race 24 of the bearing 200; and
• a sealing element 20 that is at least partially received and press-fitted within the groove 22 to configure sealing.
According to one embodiment of the present disclosure, the groove 22 is inwardly tapered such that width of the groove 22 inwardly decreases from a front face 24a. As the groove 22 is inwardly tapered, the sealing element 20 press-fits within the groove 22.
It is observed that the tapered groove 22 exerts the pressure on the sealing element 20 that facilitates sealing of a gap that is formed at an interface of the inner race 24 of the bearing 200 and the secondary rotating body (for e.g. a shaft, rolling elements 26). Due to sealing of the gap, leakage of the lubricating fluid from the interface of the inner race 24 and the secondary rotating body can be averted resulting in improved performance of the vehicles and increased service life of the vehicles.
In accordance with one embodiment of the present disclosure, the sealing element is an ‘O-ring’ made of an elastomeric material.
In accordance with another embodiment of the present disclosure, if a groove configured is not tapered then an ‘O-ring’ or a sealing element would require an additional arrangement for completely disposing the O-ring in the groove so as to facilitate sealing and avert the leakage of the lubricating fluid.
The tapered groove 22 of the present disclosure does not require an additional arrangement for fitting the sealing element (‘O-ring’) 20 in the groove 22, rather the tapered groove facilitates press-fitting of the sealing element 20 in the groove 22 and thereby facilitating effective sealing. Due to this leakage of the lubricating fluid from the interface of the inner race 24 and the secondary rotating body can be prevented. Also, the tapered groove 22 does not allow the sealing element 20 to pop-out from an open face of the tapered groove 22 or from the front face 24a of the inner race 24 of the bearing 200.
Further, the present disclosure shows that it overcomes the problems faced by the conventional bearing 100. Though the present disclosure describes about configuring seal between the interface of the inner race 24 and the secondary rotating body, but, the seal can also be configured between the interface of the outer race 30 and the secondary rotating element.
TECHNICAL ADVANCEMENTS
The technical advancements of the sealing arrangement of the bearing of the present disclosure are as follows:
• a tapered groove exerts pressure on an ‘O-ring’ that facilitates effective sealing and prevents leakage of a lubricating fluid from an interface of an inner race and a secondary rotating body (for e.g. a shaft).
• a tapered groove does not require an additional arrangement to press-fit an ‘O-ring’ in the tapered groove;
• a tapered groove exerts pressure on an ‘O-ring’ due to which the ‘O-ring’ does not pop-out from an open face of the tapered groove; and
