3. PREMABLE TO THE DESCRIPTION
þ COMPLETE

The following specification particularly describes the invention and the manner in which it is to be performed.

Field of the invention
The present invention relates to field of bearing and its assembly arrangement in the mechanical machines. More particularly, it relates to a piston having bearing plate position control arrangement operatively disposed to avoid unwanted displacement of bearing plate caused due to the occurrence of vibration while back and forth movement of piston.
Background and prior art of the invention
A mechanical machine for example baler machine is a compacting device that uses a ram to compact and compress materials into rectangular bales that can be shipped, stored, sent on for further processing, or recycled. They are designed to take similar and dissimilar waste and change them into configurations that are easy to handle and organize. The end result is a maximization of space and optimization of assets. Agricultural products and waste are baled to preserve their value and make them capable of either being properly removed or used as raw material.
Balers are chosen depending on the type of material to be baled, material loading methods, required purity, required dimensions for transport and milling, and throughput. There are many baling machines available on the market that serves particular materials and specifications.
Now referring to the types of baler machines, some manufacturers offer heavy-duty balers that have powerful pistons actuated by high-power reciprocating pumps. Their robust construction allows them to compact scraps into dense, standard-size bales. To provide back and forth movement to the piston, bearing arrangement has been provided.
Anti-friction bearings are often used in a variety of applications in which the bearing assemblies experience high external loads during operation. Externally applied loads generate contact stress between the raceways and the loaded rolling elements. Excessive radial loads on bearings are detrimental to bearing life. In some applications, bearing assembly misalignment can develop under certain loading conditions. Unwanted operational destruction and noises can be experienced, particularly during these types of high loading conditions.
One such application during which high loads are developed is on agricultural equipment. Agricultural equipment must effectively process a high volume of agricultural product in short times during harvests under conditions characterized by a high concentration of particulate matter, such as dirt, dust, moisture and plant particles. Some current balers utilize bearings which are mounted through bolts on the piston channels.
Fig. 1A & 1B depicts the conventional piston arrangement being employed in the machine like baler. Now as shown in Fig. 1A & 1B, said piston assembly (1) is provided with a side plate (1a) and a bearing mounting plate (2) being fastened with the side plate. Said side plate (1a) and the bearing mounting plate (2) are formed with a pair of vertically elongated slots (5). Each slot of side plate (6) is aligned with the respective slot (5) of the bearing mounting plate (2). Further, a bearing (3) is mounted on the mounting plate (2) between the bearing mounting slot (5). Said bearing mounting plate (2) is fastened with the side plate (1a) by providing bolts (4) within the slot. Now during to and fro movement of the piston within the chamber of the baler machine, the bolts (4) gets loosen over a period of time due to high vibration generation caused by back and forth movement of the piston. This results into sliding of bolts within the slots which cause the bearing mounting plate to move down. When said fastening means like bolts (4) and the bearing mounting plate (2) gets fallen out during the operation, fallen parts comes in between the movement of the piston which may stop the operation of piston or due to high speed movement of the piston, said fallen parts may collide with the other parts of piston, hence provide unwanted damages to the other parts of the machinery.
Further, due to generation of vibration during movement of piston may displace or misalign the bearing mounting plate from it predefined position because of loosen bolts. This may leads to separation of bearing from the rail whereon said piston movement which indirectly conducts false operation or non operation of machine.
In baler applications, but not limited to, in all those mechanical machines operated on high RPM and utilizes bearing to provide movement in machines, it is desirable provide some locking arrangement to the bearing plate. Hence, it is desperately needed to solve this technical problem by providing bearing plate position control arrangement that overcomes the difficulties as described above.
