PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

FIELD OF THE INVENTION:
This invention relates to the field of mechanical assemblies and mechanical engineering.
Particularly, this invention relates to bearing assemblies.
More particularly, this invention relates to a supplementary lubricant based runner element for bearing assembly.
BACKGROUND OF THE INVENTION:
A motor is an electromechanical assembly which comprises stator, rotor, and commutator. While the stator is the stationary part of a rotor motor system, the rotor is the non-stationary part of a rotary motor.
This invention specifically relates to axial bearings which are co-axially located with respect to a motor rotor shaft. The rotor is the non-stationary part of a rotary electric motor, electric generator or alternator, which rotates because the wires and magnetic field of the motor are arranged so that a torque is developed about the rotor's axis. In some designs, the rotor can act to serve as the motor's armature, across which the input voltage is supplied. The stationary part of an electric motor is the stator.

These bearings are placed axially with respect to a shaft which is placed co-axial to a bearing bracket or bearing housing. The bearing bracket or bearing housing is substantially a disc shaped assembly.
Each bearing is preloaded with grease or a lubricant and is defined for operation for a determined number of cycles of operation. However, there are possibilities that the grease or lubricant may be used up before the defined number of cycles due to variations in load or aberrant usage of the motor which departs from its rated use. In such an instance, non-availability of grease or a lubricant may result in excessive wear and tear of the bearing and subsequently the shaft, thereby resulting in damage to the motor itself. In high tension motors, the temperatures of operation of the motor are high. The lubricant also provides for cooling. Therefore, lack of lubrication results in inadvertent temperature rise.
Hence, there is a need for a tool or an equipment which provides for additional lubrication.
PRIOR ART:
JP 11030240 discloses a grease supplying means provided inside the space of inner bearing cover.
WO2004001242 discloses a double-row ball bearing for supporting a pulley. Chamfered portion are provided at portions that are on the inner periphery of an outer ring and close to both ends of the ring to ensure that grease is sealed in inside space and realize a structure capable of effectively using the grease.

Though, means for continuous supply of grease to bearing assembly is known, a supplementary tool or an element which aids in continuous grease supply and which acts as supplementary grease to bearing assembly while in operation is not
known.
OBJECTS OF THE INVENTION:
An object of the invention is to provide an additional lubrication mechanism to a bearing.
Another object of the invention is to prevent wear and tear or damage to a mechanical equipment due to lack or expiration of lubrication.
Yet another object of the invention is to provide a supplementary lubricant based cooling equipment.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS:
Figure 1 illustrates an operative front isometric view of shaft and bearing housing.
A shaft (12) extending from a drive end of a motor includes a co-axial bearing (21) in an outer bearing cover (20). The bearing is a revolving assembly and needs lubrication by means of a lubricant. The bearing (21) borrows support from a bearing housing (26) which is a disk shaped assembly. The lubricant may be grease or any industrial grade lubricant. The bearing includes an inlet hole (22) and an outlet chute (24) which allows for lubricant entry and exit, thereby lubricating the bearing. However, this lubrication is not sufficient. And inadvertent temperature rise needs to be curtailed by provisioning a supplementary lubricating element.
According to this invention, there is provided a supplementary lubricant based runner element for bearing assembly.
Figure 2 illustrates an operative back isometric view of shaft and bearing housing along with supplementary lubricant based runner element, with outer bearing cover, for bearing assembly.
Figure 3 illustrates an operative back close-up view of shaft and bearing housing along with supplementary lubricant based runner element for bearing assembly.

Figure 4 illustrates an operative back isometric view of shaft and bearing housing along with supplementary lubricant based runner element for bearing assembly.
Figures 5 to 8 illustrates various views of supplementary lubricant based runner element for bearing assembly.
Figure 9 illustrates a cross sectional isometric view of shaft and bearing housing along with supplementary lubricant based runner element, with outer bearing cover, for bearing assembly.
In accordance with an embodiment of this invention, there is provided a first annular ring (52) spaced apart from a co-axial second annular ring (54) with the first annular ring being connected to the second annular ring by means of a bridge element (56) in a spaced apart manner. This makes up the supplementary lubricant based runner element (100). This supplementary lubricant based runner element is a machined element.
The first annular ring (52) is preferably a solid annular ring.
The second annular ring (54) comprises holes (58) throughout the rim, each hole being spaced apart from an adjacent hole. The second annular ring is fixed to the bearing housing (26). The holes (58) in the runner element (100) are in contact with bearing gap such that the holes facilitate a pathway for lubricant directly to ball / rollers of the bearing assembly.

In accordance with another embodiment of this invention, there is provided an inner bearing cover (60) adapted to envelope the supplementary lubricant based runner element (100).
This runner element works as grease filler and rotates with the shaft. The circular holes (58) are for grease churning while rotating bearing inner race.
Ball / Rollers of the bearing assembly move / rotate in an opposite side of the actual shaft directions so that this runner element (100) has grease and also moves along with shaft, hence grease is available in the spaced apart region between the first and second rings. This grease is churned in the bearing and contact area is more for heat dissipation.
This runner element is fitted between bearing and inner bearing cover and it is, preferably, mounted on shaft with shrink fit.
