Description

Technical Field

[0001] This utility model relates to a bearing mounting structure, specifically a novel bearing mounting structure for a transformer oil pump, belonging to the field of bearing mounting technology. Background Technology

[0002] The oil pump of the traction transformer in electric locomotives is a key component of the transformer's forced circulation cooling system, employing an internal circulation cooling mode. It consists of a pump body, impeller, motor, base, end cover, bearing assembly, and sealing connections. Currently, the assembly of the bearings and bearing housings in this oil pump mostly uses an interference fit.

[0003] In existing technologies, the assembly of bearings and bearing housings mostly uses interference fits. However, when installing the bearing, it is difficult to apply pressure to the bearing perpendicular to the bearing housing, which will result in uneven stress on different parts of the bearing and increase the difficulty of installation. Therefore, a novel bearing mounting structure for transformer oil pumps is proposed here. Utility Model Content

[0004] This utility model proposes a novel transformer oil pump front bearing mounting structure, which can apply a force perpendicular to the bearing housing to the bearing, facilitating installation.

[0005] This utility model is achieved through the following technical solution: a novel transformer oil pump front bearing mounting structure, including a fixing component. The fixing component includes a fixing frame, which serves as a basic frame and provides a support structure for the installation and fixing of other components, thus stabilizing the overall structure. A bidirectional lead screw is provided on the fixing frame, and the bidirectional lead screw is rotatably connected to the fixing frame through a bearing. Both ends of the fixing frame extend to the outside of the fixing frame and are fixed with rotating rods. The bidirectional lead screw achieves transmission through rotation, which can drive two fixing blocks to move along the length direction of the bidirectional lead screw. The clamping and loosening operations of the bearing are realized through the two fixing blocks. The rotating rod is used to manually rotate the bidirectional lead screw, providing an operating component for the rotation of the bidirectional lead screw, making it convenient for operators to perform fixing and loosening operations.

[0006] Two symmetrical fixing blocks are installed on the bidirectional lead screw. Driven by the bidirectional lead screw, the fixing blocks move closer to or further away from the oil pump bearing to fix the oil pump bearing and ensure that the oil pump bearing is stable during installation. Protective pads are fixed on the side of the two fixing blocks that are close to each other. The protective pads prevent the fixing blocks from damaging the surface of the oil pump bearing and increase friction to improve the fixing effect. The two fixing blocks are set on a fixed frame, and a guide rod is fixed on the fixed frame. The guide rod is slidably connected to the two fixing blocks. The fixing blocks are slidably connected to the fixed frame through the guide rod. The guide rod provides guidance for the movement of the fixing blocks and ensures that the fixing blocks maintain linear motion during movement.

[0007] It also includes a directional component, which is mounted on a fixed component. The directional component includes a mounting plate, which serves as the basic mounting carrier for the directional component and provides structural support. A fixing sleeve is provided on the mounting plate to limit the movement of the column. A fixing plate is fixed to the upper end of the fixing sleeve. The fixing plate is fixed to the mounting plate, and the fixing sleeve is fixed to the mounting plate through the fixing plate. The fixing plate is fixed to the mounting plate with bolts to facilitate subsequent maintenance or replacement of the fixing sleeve.

[0008] A movable column is provided inside the fixed sleeve. Guide grooves are provided on both the fixed plate and the fixed sleeve. A guide strip is fixed on the movable column. The guide groove and the guide strip cooperate to provide a guide track for the movement of the movable column, limit the movement direction of the movable column, and ensure the accuracy of orientation. The guide strip is slidably disposed in the guide groove. A striking block is fixed at the upper end of the movable column. During the installation of the oil pump bearing, the striking block can be struck by external force to push the movable column and the contact block to apply a force perpendicular to the bearing seat to the oil pump bearing, thereby assisting in the installation of the oil pump bearing.

[0009] The lower end of the movable column is fixed with a contact block, which directly contacts the oil pump bearing. This ensures that the force transmitted by the striking block is evenly applied to the oil pump bearing, thus facilitating installation.

[0010] This utility model provides a novel transformer oil pump front bearing mounting structure, which has the following beneficial effects:

[0011] 1. In this new transformer oil pump front bearing mounting structure, when installing the oil pump bearing, the two fixed blocks are brought closer together by rotating the double-acting screw, thereby fixing the fixing frame and mounting plate onto the transformer oil pump. At this time, the moving column and the contact block are located directly above the center of the transformer oil pump and the oil pump bearing. The moving direction of the moving column is perpendicular to the bearing seat on the transformer oil pump. At this time, the force perpendicular to the bearing seat can be applied to the oil pump bearing by hammering the striking block, which facilitates installation. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0021] Please see Figures 1-4 The present invention proposes the following implementation scheme: a novel transformer oil pump front bearing mounting structure, including a fixing component 1, the fixing component 1 including a fixing frame 101, the fixing frame 101 serving as a basic frame, providing a support structure for the installation and fixing of other components, and playing a stabilizing role in the overall structure, the fixing frame 101 is provided with a bidirectional lead screw 102, the bidirectional lead screw 102 being rotatably connected to the fixing frame 101 through a bearing.

[0022] Both ends of the fixed frame 101 extend to the outside of the fixed frame 101 and are fixed with rotating rods 106. The bidirectional lead screw 102 achieves transmission by rotation, which can drive the two fixed blocks 103 to move along the length direction of the bidirectional lead screw 102. The clamping and loosening operations of the bearing are realized through the two fixed blocks 103. The rotating rod 106 is used to manually rotate the bidirectional lead screw 102, providing an operating component for the rotation of the bidirectional lead screw 102, making it convenient for the staff to perform fixing and loosening operations.

[0023] Please refer to this carefully. Figure 1 and Figure 2 Two symmetrical fixing blocks 103 are installed on the double-acting screw 102. Driven by the double-acting screw 102, the fixing blocks 103 move closer to or further away from the oil pump bearing 4 to complete the fixing work of the oil pump bearing 4 and ensure that the oil pump bearing 4 is stable in position during installation. Protective pads 104 are fixed on the side of the two fixing blocks 103 that are close to each other. The protective pads 104 prevent the fixing blocks 103 from damaging the surface of the oil pump bearing 4, and at the same time increase the friction and improve the fixing effect.

[0024] Two fixed blocks 103 are set on the fixed frame 101. A guide rod 105 is fixed on the fixed frame 101. The guide rod 105 is slidably connected to the two fixed blocks 103. The fixed blocks 103 are slidably connected to the fixed frame 101 through the guide rod 105. The guide rod 105 provides guidance for the movement of the fixed blocks 103, ensuring that the fixed blocks 103 maintain linear motion during the movement.

[0025] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 It also includes a directional component 2, which is mounted on the fixed component 1. The directional component 2 includes a mounting plate 201, which serves as the basic mounting carrier for the directional component 2 and provides structural support.

[0026] The mounting plate 201 is provided with a fixing sleeve 202, which can limit the movement of the column 203. A fixing plate 204 is fixed to the upper end of the fixing sleeve 202. The fixing plate 204 is fixed to the mounting plate 201. The fixing sleeve 202 is fixed to the mounting plate 201 through the fixing plate 204. The fixing plate 204 is fixed to the mounting plate 201 by bolts, so as to facilitate the subsequent maintenance or replacement of the fixing sleeve 202.

[0027] A movable column 203 is provided inside the fixed sleeve 202. Guide grooves 205 are provided on both the fixed plate 204 and the fixed sleeve 202. A guide strip 206 is fixed on the movable column 203. The guide groove 205 cooperates with the guide strip 206 to provide a guide track for the movement of the movable column 203, limit the movement direction of the movable column 203, and ensure the accuracy of orientation.

[0028] The guide bar 206 is slidably disposed in the guide groove 205. The upper end of the moving column 203 is fixed with a striking block 207. During the installation of the oil pump bearing 4, the striking block 207 can be struck by external force to push the moving column 203 and the contact block 208 to apply a force perpendicular to the bearing seat to the oil pump bearing 4, thereby assisting in the installation of the oil pump bearing 4.

[0029] The lower end of the movable column 203 is fixed with a contact block 208, which directly contacts the oil pump bearing 4. The force transmitted by the striking block 207 is evenly applied to the oil pump bearing 4, ensuring that the oil pump bearing 4 is subjected to uniform force and facilitating installation.

[0030] Working principle: When installing the oil pump bearing 4, firstly, the two fixing blocks 103 on the fixing frame 101 are fitted onto the transformer oil pump 3. Then, the bidirectional screw 102 is rotated by the rotating rod 106. Since the two fixing blocks 103 are limited by the guide rod 105, the rotation of the bidirectional screw 102 will cause the two fixing blocks 103 to move closer to each other, thereby fixing the fixing frame 101 and the mounting plate 201 onto the transformer oil pump 3. At this time, the moving column 203 and the contact block 208 are located directly above the center of the transformer oil pump 3 and the oil pump bearing 4, and the direction in which the moving column 203 can move on the fixing sleeve 202 is perpendicular to the bearing seat on the transformer oil pump 3. At this time, the force perpendicular to the bearing seat can be applied to the oil pump bearing 4 by hammering the striking block 207, which facilitates installation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
