FIELD OF THE DISCLOSURE
The present disclosure generally relates to rollers.
Particularly, the present disclosure relates to systems and methods used for
filling of rollers in a cage of a bearing.
BACKGROUND
A rolling element bearing is a bearing that carries load by placing round
elements between two pieces. The relative motion of pieces cause the round
elements to roll with very little rolling resistance and with little sliding. In a
rolling element bearing, rollers are tightly filled between the races. As the shaft
turns, each roller rolls with very little rolling resistance along with little sliding.
However, since the rollers are press fitted in a cage and supported by rings, the
rollers do not fall out under the load. Generally, rolling element bearings are of
small size, small weight, high load carrying capacity, more durability, more
accuracy, and the like.
0 There are various roller filling systems and methods available in prior art.
However, these prior art roller filling systems and methods have numerous
limitations. For example, the prior art roller filling systems and methods are
complex. Further, the prior art roller filling systems and methods are costly.
Furthermore, the prior art roller filling systems and methods are manually
operable.
Accordingly, there is need of a system for roller filling that is simple in
construction. Also, there is need of a method for roller filling that is simple in
operation. Further, there is a need of a system and a method for roller filling that
is cost effective.

Accordingly, the examples should not be construed as limiting the scope of the
embodiments herein.
The description hereinafter, of the specific embodiments will so filly 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.
The present disclosure provides a system and a method of filling of rollers. A
system and a method of roller filling disclosed in accordance with the present
disclosure is automatic and thereby requires less time for filling of rollers.
Further, a method and a system of roller filling disclosed by the present
disclosure is cost effective. Also, a method and a system of roller filling of the
present disclosure reduce labor dependency and labor cost.
Referring to Figures 1 to 6, a system of roller filling is disclosed. The system of
roller filling 100 includes a roller dropping pipe 102, a rotating roller guiding
mechanism 104, a roller pusher 106 and a cage 108 (illustrated in Figures 2 and
3). The roller dropping pipe 102 is adapted to receive rollers. Further, the roller
dropping pipe 102 is also adapted to release the rollers sequentially. In one
0 embodiment, the roller dropping pipe 102 receives rollers of specified size from
a vibrator mechanism 114 (as shown in Figure 4). The vibrator mechanism 114
includes a hopper 120. The roller dropping pipe 102 releases rollers
sequentially from an opening (not shown) configured thereon.
The rotating roller guiding mechanism 104 is adapted to receive the rollers fiom
the roller dropping pipe 102. The cage 108 is disposed at a central portion of the
rotating roller guiding mechanism 104. The rotating roller guiding mechanism
104 includes a plurality of roller fillers 110 and a plurality of recesses 112. The
plurality of roller fillers 110 is adapted to receive the rollers from the roller
dropping pipe 102. In one embodiment, each of the plurality of roller fillers 110
has a spiral shape. The plurality of recesses 112 is configured between the
adjacent roller fillers and adapted to receive the rollers from the roller fillers 110
due to rotation of the rotating roller guiding mechanism 104. In one
embodiment, each of the plurality of recesses 112 has a spiral shape. Further, in
another embodiment, each of the plurality of recesses has a depth equal to half
of the height of the rollers including a pre-determined allowance.
The spiral roller fillers 110 receive the rollers released by the roller dropping
pipe 102. The roller dropping pipe 102 is positioned in such a way that a spiral
roller filler of the plurality of spiral roller fillers 110 receives the roller from the
roller dropping pipe 102 such that half part of the roller is disposed on the spiral
roller fillers 110 and another half part is within the roller dropping pipe 102. As
the spiral roller filler 110 moves, the roller moves down to the spiral recess 112
due to rotation of the rotating roller guiding mechanism 104.
As illustrated in Figures 2 and 3, the roller pusher 106 is functionally connected
to the rotating roller guiding mechanism 104 and adapted to push the rollers
received on the recesses 112 towards cage cavities of the cage 108.
In accordance with one embodiment of the present disclosure and as shown in
Figure 5, the system of roller filling 100 includes a control panel 116 for
facilitating monitoring and control of the system 100. In accordance with
another embodiment of the present disclosure and as shown in Figure 6, the
system of roller filling 100 includes a paddle 118 for facilitating manual settings
of the system 100.
The method for filling rollers in a cage 108 of a bearing, that is centrally
disposed on the roller filling system 100, is carried out by receiving rollers
sequentially in the roller dropping pipe 102. The roller dropping pipe 102 then
I releases the rollers sequentially, wherein the roller gets guided to the spiral
roller filler 110 of the rotating roller guiding mechanism 104. The rotation of
1 the rotating roller guiding mechanism 104 causes the rotation of the spiral roller
I
I filler 110 and thereby the roller received on the spiral roller filler 110 moves
down to the spiral recesses 112. The roller pusher 106 is then actuated. The
actuation of the roller pusher 106 pushes the roller in the particular cage cavity
of the cage 108 of a bearing that is centrally disposed on the roller filling system
100. This process is repeated for a complete cycle so that all the rollers could be
filled in all the cage cavities of the cage 108 of the bearing. The complete cycle
CD is one complete rotation of the rotating roller guiding mechanism 104. More
specifically, in one rotation of the rotating roller guiding mechanism 104, rollers
are fitted in all the cage cavities of the cage 108. Once the rollers are filled in
all the cage cavities of the cage 108, the rotation of the rotating roller guiding
mechanism 104 is stopped till the positioning of another cage of another
bearing.
In one embodiment, the system 100 and the method for filling of rollers in a
cage of a bearing requires time in the range of 3-4 seconds for filling rollers in
the cage of the bearing. Accordingly, the system 100 and the method for roller
0 filling of the present disclosure requires less time for filling of rollers.
