BACKGROUND
A bearing cone is fitted within a trumpet housing of the tractor. Conventionally, the technique employed for fitting the bearing cone in the trumpet housing requires a blind operation due to which it is difficult to determine the presence of bearing cone once the trumpet housing has been assembled on the axle of the tractor. Typically, a mirror is used for detecting the presence of the bearing cone. However, the mirror used for detecting the bearing cone often gets stained due to bearing oil, which makes it cumbersome and irritating for service personnel to inspect the trumpet housing. Moreover, the process of inspecting the trumpet housing, using the mirror, is an operator dependent process which is not mandatory and can be dodged by the operator.

The absence of the bearing cone within the trumpet housing can result in a major breakdown which may require tremendous human effort to identify the reason of failure, i.e., missing bearing cone. Additionally, the absence of the bearing cone results in clattering noise from the differential box at an early operational stage which is not desired and is also very difficult to be observed during the testing process.
Therefore, there is felt a need to provide an apparatus for fitting a bearing cone within a trumpet housing of a tractor that alleviates the abovementioned drawbacks of the conventional techniques.

DETAILED DESCRIPTION
Conventionally, a bearing cone is fitted within a trumpet housing by means of a blind process. The blind process often results in failure of an operator to detect the presence of the bearing cone or inadvertent failure of the operator to fit the bearing cone within the trumpet housing. It is difficult to check the presence of the bearing cone on a bottom portion of the trumpet housing as it is placed vertically by means of a lifting arrangement. Typically, a mirror is used for detecting the presence of the bearing cone within the trumpet housing. However, the mirror used for detecting the bearing cone often gets stained due to bearing oil, which makes it cumbersome and irritating for service personnel to inspect the trumpet housing.
An apparatus 100 for fitting a bearing cone 300 within a trumpet housing 400 of a tractor, of the present disclosure, is now being described with reference to Figure 1 through Figure 7.
Referring to Figure 1-5, the apparatus 100 comprises a platform 102, a support structure 104, a dolly 106, at least one sensor 108, an input means 110, a control unit 112, and a hydraulic press 114. The support structure 104 extends vertically from the platform 102. In an embodiment, the platform 102 is supported on a plurality of support legs (not specifically labelled in the figures).
The dolly 106 is mounted on the platform 102, and is configured to receive the bearing cone 300 and subsequently the trumpet housing 400. In an embodiment, a guiding slot 116 is configured on the platform 102 to guide the movement of the dolly 106 on the platform 102. In another embodiment, a plurality of wheels (not shown in figures) is configured on an operative bottom surface of the dolly 106 to

facilitate movement of the dolly 106 on the platform 102. In still another embodiment, a rod (not shown in figures) extends from an operative bottom surface of the dolly 106 and passes though the guiding slot 116 to provide restricted movement to the dolly 106 along the guiding slot 116.
The sensor 108 is disposed on the dolly 106. The sensor 108 is configured to detect the reception of the bearing cone 300, on the dolly 106, to be inserted within the trumpet housing 400. In an embodiment, the material used for manufacturing the bearing cone is iron or steel. The sensor 108 is further configured to generate a detection signal upon detecting the reception of the bearing cone 300. In an embodiment, the sensor 108 is an inductive proximity sensor. The usage of the inductive proximity sensor ensures that the detection of the presence of the bearing cone 300 is not hindered due to dust and dirt as the inductive proximity sensor works on changing magnetic flux which is almost unaffected with a thin layer of non-inductive materials.
In an embodiment, a recess 118 is configured on the dolly 106 to facilitate housing of the sensor 108 therewithin. In another embodiment, the sensor 108 has a detection range of 1 mm.
Further, the input means 110 is configured to receive an operating command from an operator, and is further configured to generate an operating signal. In an embodiment, the input means 110 is selected from the group consisting of a push button, a touch interface, and a keypad.
The control unit 112 is configured to cooperate with the sensor and the input means. The control unit 112 is further configured to generate an actuation signal based on the detection signal and the operating signal. More specifically, the control unit 112 is configured to generate the actuation signal upon receiving the detection signal and the operating signal.

The hydraulic press 114 is mounted on the support structure 104. The hydraulic press 114 is configured to receive the actuating signal from the control unit 112. The hydraulic press 114 is further configured to apply pressure on the trumpet housing 400, against the dolly 106, to facilitate fitment of the bearing cone 300 within the trumpet housing 400. Further, referring to Figure 7, the trumpet housing 400 fitted with the bearing cone 300 is assembled with an axle 500 of the tractor.
In an embodiment, the dolly 106 has a base portion 106a, an intermediate tapered portion 106b, and a top portion 106c. The base portion 106a is configured to support the bearing cone 300. The intermediate tapered portion 106b extends from the base portion 106a and has a profile that is complementary to the profile of the bearing cone 300. More specifically, the profile of the base portion 106a is complementary to an internal profile of the bearing cone 300. The top portion 106c extends from the intermediate tapered portion 106b.
The apparatus 100 of the present disclosure employs the sensor 108 that suitably addresses the issues caused due to the conventional blind process of fitting the bearing cone 300 within the trumpet housing 400.
The apparatus 100 of the present disclosure prevents the trumpet housing 400 without the bearing cone 300 from being assembled with the axle 500 of the tractor, thereby eliminating the errors caused due to missing of the bearing cone 300 from the trumpet housing and axle assembly. The apparatus 100 averts the scenarios depicted in Figure 6, wherein the trumpet housing 400 without the bearing cone 300 is assembled with the axle 500 of the tractor.
