[0001] The invention relates to the technical field of bearing disassembly and assembly, and in particular to a connecting piece, a bearing disassembly tool and a bearing installation tool. Background Art

[0002] Bearings are common in the industrial field. For example, the end bearings of motors. The inner ring of the bearing is usually installed on the motor shaft through an interference fit, and the outer ring of the bearing is usually installed on the motor end cover through an interference fit.

[0003] Due to the lack of force points on the bearings, it is difficult to remove and install the bearings by pulling and pushing. In the prior art, violent cutting is usually used to remove the bearings, and direct knocking is usually chosen for installation. Since the bearings have no guide structure, direct knocking may cause the bearings to skew and affect the coaxiality. Summary of the invention

[0010] In an optional embodiment of the present invention, the first direction is perpendicular to the second direction.

[0011] In an optional embodiment of the present invention, a side of the second connecting portion close to the connecting rod is an arc-shaped surface, and the arc-shaped surface is used to fit the inner wall of the accommodating cavity.

[0012] In an optional embodiment of the present invention, the first connecting portion is a threaded structure.

[0013] In an optional embodiment of the present invention, a central hole for accommodating a pin on the retaining frame is formed on a side of the second connecting portion away from the connecting rod.

[0037] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] As the country promotes the application of high-efficiency and energy-saving motors, deep groove ball bearings, as the most commonly used type of rolling bearings, are widely used in high-efficiency motors and have become an important component to support the operation of motors. The application of deep groove ball bearings in motors involves some key issues in the operation of motors, especially the installation difficulties and the impact and collision inside the bearings when the bearings are replaced on site. These problems not only affect the running stability of the motor, but also shorten the service life of the bearings, thereby increasing the cost of repair and maintenance.

[0039] like Figure 1 As shown, the inner ring of the bearing 1 is usually installed on the motor shaft through an interference fit, and the outer ring is installed on the motor end cover through an interference fit. In the case of such an interference fit, the contact between the bearing 1 and the shaft or the end cover is very close, and very precise operations are required during the installation process. In the prior art, when installing the bearing 1, direct knocking or external force is often chosen. Although these methods are simple and economical, they may bring the following problems:

[0040] Since there is no effective guide structure, the bearing 1 may be subjected to uneven force during the knocking process, causing the bearing 1 to tilt, which may affect the coaxiality of the motor and even cause damage to the bearing 1.

[0041] If the bearing 1 is not accurately aligned with the axis of the shaft and the end cover during installation, it may cause deviation between the bearing 1 and the motor shaft or the end cover, resulting in coaxiality error, affecting the rotation accuracy and running stability of the motor.

[0042] When disassembling the bearing 1, since there is no special force point, violent cutting and other methods are usually required during the disassembly process. Although this method can forcibly remove the bearing 1 from the shaft or end cover, it also has many disadvantages:

[0043] Violent disassembly methods may cause damage to the inner and outer rings of the bearing 1, or even damage the motor shaft or end cover, increasing maintenance costs.

[0044] Without the right tools, the disassembly process is often laborious, requiring additional time and effort.

[0045] The bearing 1 comprises an inner ring and an outer ring, wherein the inner ring and the outer ring are spaced apart from each other in the radial direction to form an accommodating cavity for accommodating rolling elements and a retaining cage.

[0046] The inner ring is usually the core part of the bearing 1, which is directly connected to the shaft to transmit the rotational motion. The inner diameter of the inner ring is usually the diameter of the shaft or slightly larger to ensure that the bearing 1 can run smoothly on the shaft. The material of the inner ring is usually selected from high-hardness, high-wear-resistant steel to ensure that it will not deform after long-term use.

[0047] The outer ring is usually the external structure of the bearing 1, connected to the bearing 1 seat or machine housing, and fixed to the equipment. The design of the outer ring needs to be rigid enough to withstand external loads and maintain stable dimensions during long-term use.

[0048] Rolling elements are the key components in bearings 1. They roll between the inner and outer rings, providing low-friction motion. Rolling elements are usually made of steel balls, rollers or cylinders. Depending on the type of bearing 1, the shape and arrangement of the rolling elements vary.

[0049] The function of the cage is to evenly space the rolling elements to prevent them from colliding and to maintain the structural stability of the bearing 1. The cage is usually made of metal or engineering plastics, and the choice of the material depends on the use environment of the bearing 1.

[0050] The housing cavity is the gap area between the inner ring and the outer ring, which is specially used to accommodate the rolling elements and the cage. The size and shape of the housing cavity have a significant impact on the load capacity, performance and life of the bearing 1. The design of the housing cavity should ensure that the rolling elements can roll freely and minimize friction and wear.

[0051] To solve the above problems, Figure 1-3 As shown, the present invention provides a connecting member, which is applied to a bearing 1, and the connecting member includes a first connecting portion 10, a connecting rod 30 and a second connecting portion 20. The first connecting portion 10 is the starting end of the connecting member, and is used for physical connection with other components.

[0052] One end of the connecting rod 30 is connected to the first connecting part 10. The connecting rod 30 connects the first connecting part 10 and the second connecting part 20. The connecting rod 30 plays an intermediary role here, connecting the first connecting part 10 and the second connecting part 20. Its structure is equivalent to a bridge for transmitting force and motion in the bearing 1 system.

[0053] The second connecting portion 20 is connected to the other end of the connecting rod 30, and the second connecting portion 20 is used to be inserted into the gap between the retaining frame and the accommodating cavity. The second connecting portion 20 is used to connect the bearing 1,

[0054] like Figure 3As shown, the maximum dimension of the second connecting part 20 in the first direction is smaller than the minimum spacing between the inner ring and the outer ring, ensuring that the connecting part can be smoothly inserted between the inner ring and the outer ring of the bearing 1. This dimension design ensures that the bearing 1 will not be obstructed during operation, thereby not affecting the normal operation of the bearing 1. The maximum dimension of the second connecting part 20 in the second direction is larger than the minimum spacing between the inner ring and the outer ring, and this design ensures that it can have enough contact surface in the accommodating cavity of the bearing 1 to withstand a certain force transmission. It must not only adapt to the structure of the bearing 1, but also ensure that it provides sufficient and stable support during operation. The maximum dimension of the second connecting part 20 in the axial direction of the connecting rod 30 is smaller than the axial spacing between the retaining frame and the accommodating cavity, ensuring that the second connecting part 20 will not interfere with the retaining frame. The first direction and the second direction are both radial directions of the connecting rod 30.

[0055] like Figure 3 As shown, the first direction is perpendicular to the second direction. In this way, the second connection part 20 can be inserted into the accommodating cavity and then rotated 90 degrees to form a limit. After rotating 90 degrees, the maximum dimension of the second connection part 20 in the second direction is greater than the minimum spacing between the inner ring and the outer ring, which ensures that the second connection part 20 can be fixed in the accommodating cavity to form a limit structure. Through the 90-degree rotation, the cross-section of the connector changes, limiting its further movement in the accommodating cavity. In this way, the second connection part 20 of the connector is locked inside the bearing 1, forming a stable mechanical connection.

[0056] like Figure 2 As shown, the side of the second connecting portion 20 close to the connecting rod 30 is an arc-shaped surface, and the arc-shaped surface is used to fit the inner wall of the accommodating cavity. The surface contour of the arc-shaped surface can better fit the inner wall of the accommodating cavity, so that the force of the connecting piece is evenly distributed. This helps to reduce the situation where the local stress on the contact surface is too large and avoids excessive local wear. The design of the arc-shaped surface can effectively disperse the force transmitted from the connecting piece to the inner wall of the accommodating cavity, prevent the inner wall from being directly impacted or subjected to high stress concentration, and protect the accommodating cavity from damage. Over time, this design helps to extend the service life of the accommodating cavity.

[0057] like Figure 2 As shown, the first connection part 10 is a threaded structure. A threaded structure is a mechanical method of connecting objects by meshing of threads. By screwing a component with an external thread (usually a bolt or a screw) into another component with an internal thread (such as a nut or a hole groove), a very strong and stable connection can be achieved. The threaded connection maintains the stability of the connection through the meshing force and friction of the two components.

[0058] like Figure 2As shown, a center hole for accommodating the pin on the retainer is provided on the side of the second connecting part 20 away from the connecting rod 30. The retainer is usually provided with a pin. By providing a center hole on the side of the second connecting part 20 away from the connecting rod 30, the pin on the retainer does not conflict with the inserted portion of the second connecting part 20. In this way, the second connecting part 20 can be smoothly inserted to a sufficient depth, thereby ensuring the stability and strength of the structural connection. By providing a center hole on the side of the second connecting part 20 away from the connecting rod 30, the pin on the retainer does not conflict with the inserted portion of the second connecting part 20. In this way, the second connecting part 20 can be smoothly inserted to a sufficient depth, thereby ensuring the stability and strength of the structural connection.

[0059] like Figure 4-5 As shown, the present invention further proposes a bearing 1 disassembly tool, which is applied to the bearing 1 installed on the rotating shaft 2, including a connecting piece, a pull rod 40, an adapter seat 50 and a push unit 60.

[0060] There are multiple connectors. The multiple connectors can ensure that the tooling does not loosen or shift during use, ensure the stability of the entire disassembly process, and avoid accidental damage during the disassembly process due to loose connections. Through multiple connectors, the external force applied to the bearing 1 can be effectively dispersed to reduce local stress concentration.

[0061] The pull rod 40 is connected to the first connecting portion 10. The pull rod 40 is connected to the first connecting portion 10, and its main function is to connect the adapter 50 and the connecting member to bear the force applied during the disassembly process. The pull rod 40 is usually used to transmit external force to ensure that the relative positions of the components remain unchanged during the disassembly process.

[0062] The adapter 50 is connected to the pull rod 40. The adapter 50 is a component connecting the pull rod 40 and the push unit 60. Its function is to transmit the force of the push unit 60 to the pull rod 40 and help remove the bearing 1 from the rotating shaft 2. The adapter 50 is usually used to support the push unit 60 to ensure more accurate force transmission during the disassembly process. The adapter 50 is specifically a turntable structure.

[0063] The pushing unit 60 is connected to the adapter seat 50, and the pushing unit 60 is used to push the end of the rotating shaft 2 to make the adapter seat 50 away from the rotating shaft 2. The pushing unit 60 can be a pneumatic push rod, a hydraulic push rod or the like. Specifically, the pushing unit 60 is a pushing screw threadedly connected to the adapter seat 50. The pushing unit 60 is the core operating part of the entire disassembly tool. The pushing screw is threadedly connected to the adapter seat 50, and is used to directly push the end of the rotating shaft 2 to remove the bearing 1 from the rotating shaft 2. Since the pushing unit 60 is usually threaded, the pushing force can be finely adjusted to ensure that the disassembly process can be carried out smoothly and evenly, especially when disassembling a tight or stuck bearing 1, it can effectively avoid damage to the rotating shaft 2 or the bearing 1 caused by excessive force.

[0064] How to use the disassembly tool

[0065] Connecting piece and rotating shaft:

[0066] The connector can help to firmly connect the entire tool to the shaft 2 or bearing 1. This step ensures that the force in the subsequent operation can be stably transmitted to the shaft 2 to prevent the tool from loosening or misaligning during the disassembly process. The connection between the connector and the shaft 2 ensures that the bearing 1 disassembly tool will not slip or deviate during operation, thereby enhancing the safety and stability of the disassembly process.

[0067] Install bearing 1 disassembly tool:

[0068] When installing the bearing 1 disassembly tool, the other parts of the tool, such as the tie rod 40, adapter 50 and push unit 60, will maintain a stable fit with the connector. The installation of the tool usually requires ensuring that the tie rod 40, adapter 50 and push unit 60 can maintain a proper position between the bearing 1 and the shaft 2 to ensure that no damage is caused to other parts during the disassembly process. After the bearing 1 disassembly tool is installed, the tool is in working condition and can directly act on the bearing 1 and the shaft 2. This step ensures that the various parts of the tool are correctly connected to the disassembly target and ensures the smooth progress of the disassembly operation.

[0069] The pushing unit 60 pushes the end of the rotating shaft 2:

[0070] When the push unit 60 starts working, it applies force to the end of the shaft 2 through the threaded push screw. Due to the threaded structure, the push unit 60 can accurately control the force applied. This applied force gradually causes the bearing 1 to be separated from the shaft 2. The pushing action of the push unit 60 is a key part of the removal tool, which helps to push the bearing 1 out through a continuous and uniform force push. This process must be careful and gradual, because excessive thrust may cause damage to the bearing 1, the shaft 2 or the removal tool itself.

[0071] Pull the pull rod 40 to drive the bearing 1 away from the rotating shaft 2:

[0072] When the push unit 60 applies the push force, the pull rod 40 bears the pulling force or pushing force from the push unit 60, and transmits the force to the bearing 1 through the adapter 50. The pull rod 40 guides the push force to the contact surface of the bearing 1. Through the force transmission, the pull rod 40 gradually pulls the bearing 1 and separates it from the rotating shaft 2. The function of the pull rod 40 is to convert the force applied by the push unit 60 into axial pulling force and ensure the smooth pulling process. The design of the pull rod 40 needs to have sufficient rigidity and strength to avoid bending or breaking during the disassembly process.

[0073] In an optional embodiment of the present invention, the adapter 50 is detachably connected to the pull rod 40. Figure 5 As shown, the specific adapter 50 is provided with a through hole for the pull rod 40 to pass through, and the pull rod 40 is a threaded structure. A nut is threadedly connected to the pull rod 40, and the length adjustment function of the pull rod 40 is achieved by changing the position of the nut. When the thread of the pull rod 40 is connected to the nut, the position of the nut can be moved up and down as needed, thereby changing the working length of the pull rod 40. Specifically, adjusting the position of the nut can effectively extend or shorten the effective working length of the pull rod 40. When designing a disassembly tool, it is often considered that it needs to adapt to bearings 1 and rotating shafts 2 of different specifications and sizes. By adjusting the length of the pull rod 40, the disassembly tool can flexibly adapt to workpieces of different sizes to ensure the smooth progress of the disassembly process.

[0074] like Figure 6-8 As shown, the present invention further proposes a bearing 1 installation tool, including a connecting piece and a guide sleeve 70.

[0075] There are multiple connectors. A nut is provided at the first connection end to connect to the guide sleeve 70. The number and configuration of the connectors can be adjusted according to the type and installation requirements of the bearing 1 to ensure the applicability and versatility of the tooling. Different combinations of connectors can achieve different installation angles, support methods and more complex installation tasks.

[0076] like Figure 7 As shown, the guide sleeve 70 is connected to the first connecting portion 10, and the outer diameter of the guide sleeve 70 is equal to the outer diameter of the bearing 1. This ensures that the guide sleeve 70 can perfectly fit the bearing 1, providing a precise guide for the installation process. The guide sleeve 70 can effectively guide the bearing 1 to enter its installation position along the correct trajectory, avoiding problems such as misalignment, tilting or jamming caused by the bearing 1 not being aligned with the installation position.

[0077] like Figure 7As shown, a guide section is provided at the end of the guide sleeve 70 away from the bearing 1, and the outer diameter of the guide section gradually increases from the end away from the bearing 1 to the end close to the bearing 1. In this way, the bearing 1 can be effectively guided to enter the installation position smoothly. During the installation of the bearing 1, the guide section acts like a progressive guide, gradually guiding the bearing 1 from the far end of the guide sleeve 70 to the end close to the bearing 1, so that the guiding process of the bearing 1 is smoother. Traditional bearing 1 installation usually requires a large force to correctly place the bearing 1 into the bearing 1 seat or the bearing 1 hole. By using the guide sleeve 70 and the guide section, not only can the difficulties caused by incorrect angles be avoided during installation, but also smooth guidance can be achieved, making the installation process more labor-saving. This greatly reduces the force required by the operator during the installation process, reducing fatigue or injury caused by improper operation.

[0078] The steps for using the bearing 1 installation tool are as follows.

[0079] Bearing 1 shrink fit installation:

[0080] Shrink-fit installation refers to heating the bearing 1 to expand it, so that the bearing 1 can be inserted into the shaft 2 or the bearing 1 seat. Usually, after the bearing 1 is heated to an appropriate temperature, its outer diameter will expand, making installation easier. As the temperature drops, the bearing 1 will shrink and be firmly fixed in the shaft 2 or the bearing 1 seat. This process can effectively avoid damage to the bearing 1 due to excessive force during installation, especially when installing a relatively large bearing 1. The shrink-fit method can reduce the risk of damage to the bearing 1 during installation.

[0081] The connecting piece connects the guide sleeve 70 to the bearing 1:

[0082] During the installation process, the connector plays a role in fixing and connecting, ensuring that the guide sleeve 70 can be firmly connected to the end face of the bearing 1. The design of the connector must take into account the precise fixation of the guide sleeve 70 and avoid the bearing 1 from being offset or inaccurately installed due to unstable connection during the installation process. The precise fit of the guide sleeve 70 ensures that the bearing 1 always maintains the correct position during connection.

[0083] The guide sleeve 70 guides the bearing 1 to be installed on the motor end cover:

[0084] After the connector securely fixes the guide sleeve 70 to the end face of the bearing 1, the guiding function of the guide sleeve 70 begins to play a key role. Guided by the guide sleeve 70, the bearing 1 can smoothly slide into the end cover of the motor along the correct path. This process ensures that the mounting holes of the bearing 1 and the motor end cover are coaxial, avoiding the misalignment or oblique insertion that may occur in traditional installation methods, thereby improving the coaxiality and running accuracy of the bearing 1.

[0085] like Figure 2, 8 As shown, the connecting rod 30 is provided with a polygonal block 31, and the guide sleeve 70 is provided with a polygonal hole 71, and the polygonal hole 71 is used to accommodate the polygonal block 31 to form a non-rotation fit. The core purpose of the non-rotation fit is to ensure that the connecting part does not disengage or loosen during the rotation process through the structural fit of the polygonal block 31 and the polygonal hole 71. Prevent the second connecting part 20 from disengaging from the bearing 1 due to rotation. The specific polygonal block 31 and the polygonal hole 71 are square blocks and directional holes.

[0086] In summary, the present invention proposes a connector, a bearing 1 disassembly tool and a bearing 1 installation tool. Through the design of a special connector, the present invention can provide additional support and stability when disassembling and installing the bearing 1. In particular, when the bearing 1 needs to withstand a large disassembly force or installation force, the connector can effectively share and transmit these external forces, avoiding the risk of damage to the bearing 1 or structural deformation that may occur in traditional disassembly and installation. Precision is crucial during disassembly and installation, especially when dealing with high-precision bearings 1, any position deviation may lead to installation failure or equipment failure. The present invention ensures that the bearing 1 can be accurately docked during disassembly and installation through the precise design of a special connector, thereby improving the operating accuracy. The traditional bearing 1 disassembly and installation method may require complex tools and multiple steps, but through the design of a special connector, the present invention can simplify these steps, making the entire process simpler and more efficient. The design of the connector can cooperate with the bearing 1, reducing the dependence on other disassembly and installation tools, saving man-hours and reducing the complexity of the operation. In the traditional disassembly and installation process of the bearing 1, the operator often needs greater strength or relies on complex equipment. The connector design of the present invention makes the whole operation more convenient by improving the adaptability of the disassembly and installation tools. Whether during installation or disassembly, the use of a dedicated connector can simplify the process and enable the operator to complete the task more conveniently and quickly.
