As described in the background section, typically, the bearing housing B in the belt conveyor is fixedly connected to the support plate (a plate-like structure for supporting and fixing the bearing housing or other related components to ensure that the bearing housing or other related components are in the correct positions and bear the corresponding loads) by bolts. In the prior art, when the bearing needs to be disassembled, the bolts between the bearing seat B and the supporting plate need to be disassembled firstly, and then the bearing seat B is disassembled from the rotating shaft C. The whole disassembly process is complicated, and the disassembly is inconvenient because the disassembly process is possibly limited by space.

Therefore, referring to fig. 1 to 5, the bearing dismounting device of the present application includes a main plate 1, a connecting rod 3, and an abutment screw 2. The main plate 1 has a first threaded hole 11 and a through hole 12. The first screw hole 11 and the through hole 12 each extend in the thickness direction of the main plate 1 and penetrate the main plate 1. The connecting rod 3 is configured to be inserted into the through hole 12 and fixedly connected with the bearing housing B of the bearing a to be disassembled. The abutment screw 2 is threadedly engaged with the first threaded hole 11 so as to be movable relative to the main plate 1. The abutment screw 2 is used for abutting against the rotating shaft C and exerting force on the rotating shaft C. The bearing A to be disassembled is arranged on the rotating shaft C. When dismantling bearing A, need not to dismantle the fixing bolt between bearing frame B and the backup pad, directly with connecting rod 3 and the bolt fastening back that is used for being connected with the backup pad on bearing frame B, pull out bearing frame B together with the backup pad from pivot C, the dismantlement process is comparatively convenient, improves and dismantles efficiency, and bearing dismounting device simple and convenient structure, occupation space is little, and maneuverability is high.

Specifically, after the connecting rod 3 is connected to the bearing seat B, a certain distance is provided between one end of the abutment screw 2 for abutting against the rotating shaft C and the rotating shaft C, an external force is applied to the abutment screw 2, so that the abutment screw 2 moves towards the rotating shaft C and abuts against the end surface of the rotating shaft C, at this time, the external force is continuously applied to the abutment screw 2, and since the abutment screw 2 cannot continuously move, the connecting rod 3 drives the bearing seat B and the bearing a to move together relative to the rotating shaft C under a reaction force (i.e., the distance between the bearing a and the bearing seat B and the main board 1 is gradually shortened), so as to detach the bearing a. Referring to fig. 2, in some embodiments, the through hole 12 includes a long hole. The connecting rod 3 is penetrated in the long hole so that the position of the connecting rod 3 can be adjusted. Through making connecting rod 3 remove in the slot hole, adjust the position of connecting rod 3, make bearing dismounting device can match with the bearing frame of different specifications, increase the suitability.

Referring to fig. 2, in some embodiments, the motherboard 1 includes a plurality of through holes 12. The plurality of through holes 12 are spaced apart in the circumferential direction centering on the first screw hole 11. The bearing dismounting device comprises a plurality of connecting rods 3. The plurality of connecting rods 12 distributed at intervals are arranged to be connected with a plurality of bolts on the bearing seat B, so that stability of the bearing seat B during fixing is improved, stress uniformity of the bearing seat B in the disassembling process is improved, and the disassembling process is smoother.

Still further, in some embodiments, the motherboard 1 includes four through holes 12. The bearing dismounting device comprises at least two connecting rods 3 which are selectively arranged in the four through holes in a penetrating way. For example, the bearing dismounting device includes two connecting rods 3, and two connecting rods 3 are provided to penetrate in some two of the four through holes 12. Or comprises four connecting rods 3, and the four connecting rods 3 are respectively penetrated in the four through holes 12.

Referring to fig. 3, in some embodiments, the abutment screw 2 comprises a first body section 21 and a force receiving portion 22. The outer surface of the first body section 21 is provided with an external thread. The first end of the first body section 21 is adapted to abut the spindle C. The force receiving portion 22 is provided at the second end of the first body section 21. The force-receiving portion 22 is used for being acted by an external force to drive the first main body section 21 to rotate through the first threaded hole 11 so as to move relative to the main board 1. The provision of the force receiving portion 22 facilitates the application of force to the abutment screw 2, facilitating the rotation of the first body section 21.

Referring to fig. 3, in some embodiments, the force-receiving portion 22 includes a hex head. Thus, the universal tool is convenient to use to be matched with the stress part 22, for example, the wrench is clamped with the hexagonal head, and the screw rod 2 can be rotated and abutted by applying the acting force to the wrench.

Referring to fig. 4, in some embodiments, the connecting rod 3 includes a second body section 31 and a connector 32. The second body section 31 is disposed through the through bore 12. A connector 32 is provided at an end of the second body section 31, the connector 32 being for connection with the bearing housing B. The radial dimension of the connector 32 is larger than the radial dimension of the second body section 31 to improve the stress stability of the connector 32 when connected with the bearing seat B.

Referring to fig. 4, in some embodiments, the connecting rod 3 includes a second threaded hole 33 provided on the connecting head 32. The second threaded hole 33 is for connection with a fixing bolt on the bearing housing B. Specifically, in this embodiment, the fixing bolt refers to a fixing bolt that the bearing housing B is connected to the support plate, and the second screw hole 33 is engaged with the fixing bolt, so that the bearing a can be removed without removing the bearing housing B from the support plate in advance.

Referring to fig. 1, in some embodiments, the bearing removal device further comprises a fastener 4. The fastener 4 is used for fastening the second body section 31 after the connector 33 is matched with the fixing bolt, so that the second body section 31 is relatively fixed with the main board 1. Specifically, the fastener 4 includes a lock nut, an external thread is provided on the second main body section 31, and an internal thread of the lock nut is matched with an external thread on the second main body section 31, so that the lock nut moves on the second main body section 31 toward the main board 1 by rotating the tightening nut until the lock nut is tightly attached to the main board 1, and fastening of the second main body section 31 is completed.

In some embodiments, the length of the abutment screw 2 is greater than the length of the connecting rod 3. Specifically, after the abutment screw 2 abuts against the rotating shaft C, as shown in fig. 5, the abutment screw 2 continues to be applied with a force in this state, since the abutment screw 2 cannot continue to move, the connecting rod 3 and the main plate 1 remain relatively fixed and move together with respect to the abutment screw 2, and the length of the abutment screw 2 is greater than the length of the connecting rod 3 on the side of the main plate 1 away from the bearing a, thereby leaving a space for the connecting rod 3 to move with respect to the abutment screw 2 with respect to the main plate 1, and further pulling the bearing a and the bearing housing B from the rotating shaft C as the force continues to be applied to the abutment screw 2.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same; while the application has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present application or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the application, it is intended to cover the scope of the application as claimed.
