Description

Technical Field

[0001] This utility model relates to the field of engineering machinery maintenance tools, and in particular to a bulldozer drive gear bearing separation tool. Background Technology

[0002] Separating the drive gears and bearings is a common and challenging task in bulldozer maintenance. Traditional separation methods often have several problems. For example, using simple tools like pry bars is not only laborious but also prone to damaging the drive gears and bearings, affecting their lifespan and the overall performance of the equipment. Furthermore, some existing separation tools are not specifically designed for bulldozer drive gears and bearings and cannot adequately adapt to their structural characteristics, resulting in low separation efficiency and increased maintenance costs. Therefore, there is an urgent need for a tool specifically designed for separating bulldozer drive gears and bearings to address the problems of inconvenient operation, easy damage to components, and low separation efficiency in existing technologies. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bulldozer drive gear bearing separation tool. This tool can conveniently and efficiently separate the bulldozer drive gear from the bearing, avoiding damage to the drive gear and bearing during the separation process, and improving the efficiency and quality of maintenance work.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bulldozer drive gear bearing separation tool, comprising:

[0006] Top plate: As the basic support component of the entire tool, it plays a role in connecting and transmitting force;

[0007] Jack: Movable between the bearing and the top plate, its main function is to generate an upward thrust to press against the top plate and bearing, thereby separating the drive gear from the bearing. The selection of the jack can be determined according to the specifications of the drive gear and bearing that need to be separated. For example, a hydraulic jack with a rated load of [X] tons can be selected to ensure sufficient separation force.

[0008] Connecting rod: Located between the top plate and the drive gear, it is used for detachable connection between the top plate and the drive gear. The connecting rod securely connects the top plate to the drive gear, allowing the thrust generated by the jack to be effectively transmitted to the drive gear, thereby achieving separation from the bearing.

[0009] Furthermore, the top plate is provided with several mounting holes arranged in a ring. The connecting rod passes sequentially through the process hole of the drive gear and the mounting hole of the top plate. Limiting elements are provided at both ends of the connecting rod to constrain the top plate and the drive gear onto the connecting rod. This design makes the connection between the connecting rod and the top plate and the drive gear more stable, ensuring uniform force transmission during separation and preventing loosening or displacement.

[0010] Furthermore, the limiting components are a stop block and a limiting pin. The stop block is fixed to one end of the connecting rod, and the other end of the connecting rod has a connecting hole into which the limiting pin is inserted. The stop block acts as a barrier to prevent the drive gear from falling off the connecting rod during the separation process, while the limiting pin further ensures the stability of the connection between the connecting rod and the drive gear.

[0011] Furthermore, to facilitate adjustment of the position of the limiting pin, the connecting hole is designed as an elongated hole. This allows for flexible adjustment of the insertion position of the limiting pin according to the specific location of the process hole in the drive gear during actual operation, improving the tool's versatility and adaptability.

[0012] Furthermore, the stop block is a circular block, centrally located. The circular design allows for the even distribution of force from the drive gear, preventing damage to the stop block or the drive gear due to uneven force distribution. Central positioning further ensures balanced force transmission.

[0013] Furthermore, to improve the robustness of the connection between the stop block and the connecting rod, the stop block and the connecting rod are integrally connected. This integral connection reduces weak points at the connection point and enhances the overall structural strength and stability.

[0014] Furthermore, the limiting pin is designed in an L-shape. The L-shaped limiting pin facilitates operation, making insertion and removal from the connecting hole more convenient and quick, while also providing a better limiting function.

[0015] Furthermore, to protect the jack and bearing, a pad is placed at the bottom of the jack, positioned between the jack and the bearing. The pad disperses the pressure of the jack on the bearing, preventing damage to the bearing due to excessive local pressure.

[0016] Furthermore, the pad is a cylindrical wooden block. Cylindrical wooden blocks have good compressive strength and cushioning effect, while being low in cost and easy to obtain and replace.

[0017] Furthermore, to further improve the stability of the tool and its guiding effect on the jack, a limiting cylinder is fixedly connected to the center of the top plate. The limiting cylinder cooperates with the telescopic shaft of the jack. The limiting cylinder ensures that the jack remains vertical during operation, avoiding uneven separation force caused by jack tilt, which would affect the separation effect.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The separation force is provided by a jack, which is easy to operate, greatly reduces the labor intensity of maintenance personnel, and improves the efficiency of separation work.

[0020] 2. The combination design of connecting rod, top plate and limiting component can stably connect drive gear and tool, ensure uniform force transmission during separation, effectively avoid damage to drive gear and bearing, extend the service life of components and reduce maintenance costs.

[0021] 3. The tool's components are designed reasonably, giving it good versatility and adaptability, making it suitable for separating drive gears and bearings of various bulldozers.

[0022] 4. The cooperation between the limiting cylinder at the center of the top plate and the telescopic shaft of the jack improves the stability of the jack during operation, further ensuring the smooth progress of the separation work and the reliability of the separation effect.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a bulldozer drive gear bearing separation tool includes components such as a top plate 1, a jack 2, and a connecting rod 3. The top plate 1 is placed in a suitable position so that it can correspond to the drive gear 8 and the bearing 9.

[0029] The jack 2 is positioned between the bearing 9 and the top plate 1 to ensure that the jack 2 is in a stable position and can work normally.

[0030] The connecting rod 3 is passed through the process hole of the drive gear 8 and the mounting hole 11 of the top plate 1 in sequence. At this time, the drive gear 8 and the top plate 1 are initially connected through the connecting rod 3.

[0031] A stop block 4 is fixed at one end of the connecting rod 3. The stop block 4 is a circular block and is integrally connected with the connecting rod 3. It is centrally located at the end of the connecting rod 3.

[0032] A connecting hole is made at the other end of the connecting rod 3, and an L-shaped limiting pin 5 is inserted into the connecting hole 31, thereby firmly fixing the top plate 1 and the drive gear 8 on the connecting rod 3, completing the connection and installation of the tool and the drive gear 8.

[0033] When jack 2 is activated, it generates an upward thrust that presses against top plate 1 and bearing 9. As jack 2 continues to rise, drive gear 8 gradually separates from bearing 9, achieving efficient separation of drive gear 8 and bearing 9.

[0034] Example 2

[0035] Following the steps of Example 1, complete the preparation of the tool and the initial connection with the drive gear 8.

[0036] Since the process hole position of the drive gear 8 in this embodiment is different from that in embodiment one, the design feature of the connecting hole being an elongated hole is utilized. Based on the actual position of the process hole of the drive gear 8, the insertion position of the limiting pin 5 in the connecting hole is adjusted to ensure that the connecting rod 3 and the drive gear 8 are firmly connected.

[0037] A cylindrical wooden block 6 is placed at the bottom of the jack 2. The block 6 is located between the jack 2 and the bearing 9 to protect the bearing 9 from excessive pressure.

[0038] Start jack 2 and, following the operating procedure of Example 1, separate drive gear 8 from bearing 9. During the separation process, the cushioning effect of pad 6 effectively protects bearing 9, preventing damage due to excessive local pressure.

[0039] Example 3

[0040] Similarly, tools are prepared and initial connections are made. Unlike the previous two embodiments, the drive gear 8 and bearing 9 are larger in size and require greater separation force.

[0041] Check whether the limiting cylinder 7 fixedly connected to the center of the top plate 1 and the telescopic shaft of the jack 2 are properly matched to ensure that the jack 2 can maintain a vertical state during operation.

[0042] Following the operating steps of Embodiments 1 and 2, the separation of the drive gear 8 and bearing 9 was completed. Throughout the process, the guiding effect of the limiting cylinder 7 on the jack 2 made the jack 2 work more stably and the separation force more uniform, successfully completing the separation task of the large-size drive gear 8 and bearing 9.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
