Description

Technical Field

[0001] This utility model relates to the field of tooling and provides a gearbox bearing disassembly device. Background Technology

[0002] During the maintenance of high-speed train gearboxes, removing the bearings on both sides of the drive gear is one of the most crucial steps.

[0003] Currently, the common method of unloading is to fix the drive gear on the unloading fixture, first unload the bearing on one side of the motor, then manually flip the gear and re-clamp it, and finally unload the wheel bearing on the other side.

[0004] Because the drive gear weighs approximately 30 kg, loading, unloading, clamping, and gear flipping are all done manually. While this method can accomplish the unloading task, it has significant drawbacks:

[0005] First, the operation is quite strenuous, and repeating these actions for a long time will have an adverse effect on the operator's physical health.

[0006] Secondly, the uncertainty of manual operation increases the safety risks during the operation process and may cause accidental injuries;

[0007] Finally, because all steps are completed manually, the work efficiency is low and cannot meet production requirements, especially in situations where frequent maintenance and repairs are required. Utility Model Content

[0008] This utility model provides a gearbox bearing disassembly device to solve the defects of difficult disassembly of gearbox bearings in related technologies.

[0009] This utility model embodiment provides a gearbox bearing disassembly device, including:

[0010] Support base;

[0011] The first snap-fit ​​plate is used to abut against the end face of the wheel-side bearing that is away from the motor-side bearing;

[0012] The second snap-fit ​​plate is disposed above the first snap-fit ​​plate and overlaps the support base along the height direction of the support base. The second snap-fit ​​plate is used to abut against the end face of the motor side bearing that is away from the wheel side bearing.

[0013] An extrusion column is provided along the height direction of the support base. The first end of the extrusion column is connected to the first snap-fit ​​plate, and the height of the second end of the extrusion column is different from the height of the shaft end of the gearbox.

[0014] A pressure-applying component is disposed above the extrusion column. During the application of pressure by the pressure-applying component, the pressure-applying component is used to apply pressure to at least one of the second end of the extrusion column and the shaft end.

[0015] According to one embodiment of the present invention, a pad is further included, the pad being detachably mounted on the end of the shaft facing the pressure member.

[0016] According to one embodiment of the present invention, an elastic recovery member is sleeved on the extrusion column, and the two ends of the elastic recovery member abut against the second end of the extrusion column and the second snap-fit ​​plate.

[0017] According to one embodiment of the present invention, a limiting member is provided at the second end of the extrusion column, and the two ends of the elastic recovery member abut against the limiting member and the second snap-fit ​​plate.

[0018] According to one embodiment of the present invention, a through hole is provided on the second snap-fit ​​plate, and the extrusion post passes through the through hole.

[0019] According to one embodiment of the present invention, a first receiving groove is provided on the first snap-fit ​​plate, and the shape of the first receiving groove is adapted to the shape of the wheel side bearing;

[0020] The second snap-fit ​​plate is provided with a second receiving groove, the shape of which is adapted to the shape of the motor side bearing.

[0021] According to one embodiment of the present invention, the edge of the first snap-fit ​​plate is provided with a first mounting groove, and the wheel side bearing is adapted to be mounted on the first snap-fit ​​plate through the first mounting groove.

[0022] The edge of the second snap-fit ​​plate is provided with a second mounting groove, and the motor-side bearing is adapted to be mounted on the second snap-fit ​​plate through the second mounting groove.

[0023] According to one embodiment of the present invention, a third snap-fit ​​plate is further included. The third snap-fit ​​plate is disposed on the side of the first snap-fit ​​plate facing the second snap-fit ​​plate. During the pressing process of the pressure-applying member, the third snap-fit ​​plate is used to snap the drive gear.

[0024] According to one embodiment of the present invention, a limiting platform is provided on the support base. During the pressure application process of the pressure-applying component, the limiting platform is adapted to cooperate with the third snap-fit ​​plate to limit the removal of the drive gear.

[0025] According to one embodiment of the present invention, a positioning element is provided on the support base, and the third snap-fit ​​plate is adapted to limit its relative position with the support base by means of the positioning element along the height direction of the support base.

[0026] According to the gearbox bearing disassembly device provided in this embodiment, the upper and lower arrangement of the first and second clamping plates enables simultaneous clamping of the wheel-side bearing and the motor-side bearing, reducing the time spent on repeated installation and positioning of the wheel-side bearing and the motor-side bearing. The height difference design between the end face of the extrusion column and the shaft end avoids direct impact on the shaft end during pressure application, reducing the risk of gearbox main shaft deformation. Furthermore, the height difference design between the end face of the extrusion column and the shaft end allows the pressure-applying component to initially contact only the end face of the extrusion column or only the end face of the shaft end. When the end face of the extrusion column is higher, the pressure-applying component, through contact with the end face of the extrusion column, drives the first clamping plate to move, thus preferentially pressing out the wheel-side bearing. When the end face of the extrusion column is flush with the end face of the shaft end, the pressure-applying component, through contact with the end face of the shaft end, drives the second clamping plate to move, pressing out the gear-side bearing, thereby improving the disassembly efficiency of the gearbox bearing. Conversely, if the end face of the extrusion column is lower, the pressure-applying component will preferentially contact the end face of the shaft during the pressure application process. The pressure-applying component will drive the second snap-fit ​​plate to move, which can preferentially press out the gear side bearing. When the end face of the shaft is flush with the end face of the extrusion column, the pressure-applying component can contact the end face of the extrusion column to drive the first snap-fit ​​plate to move, thereby pressing out the wheel side bearing.

[0031] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0032] like Figure 1 As shown, this utility model embodiment provides a gearbox bearing disassembly device, including:

[0033] Support base 100;

[0034] The first snap-fit ​​plate 102 is used to abut against the end face of the wheel-side bearing 104 that is away from the motor-side bearing 108.

[0035] The second snap-fit ​​plate 106 is positioned above the first snap-fit ​​plate 102 and overlaps the support base 100 along the height direction of the support base 100. The second snap-fit ​​plate 106 is used to abut against the end face of the motor side bearing 108 that is away from the wheel side bearing 104.

[0036] The extrusion column 110 is arranged along the height direction of the support base 100. The first end of the extrusion column 110 is connected to the first snap plate 102. The height of the second end of the extrusion column 110 is different from the height of the shaft end 128 of the gearbox.

[0037] A pressure-applying element is disposed above the extrusion column 110. During the application of pressure by the pressure-applying element, the pressure-applying element is used to apply pressure to at least one of the second end and the shaft end 128 of the extrusion column 110.

[0038] According to the gearbox bearing disassembly device provided in this embodiment of the present invention, the upper and lower arrangement of the first clamping plate 102 and the second clamping plate 106 enables the synchronous clamping of the wheel-side bearing 104 and the motor-side bearing 108, reducing the time spent on repeated installation and positioning of the wheel-side bearing 104 and the motor-side bearing 108. The height difference design between the end face of the pressing column 110 and the shaft end 128 avoids direct impact on the shaft end 128 during pressure application, reducing the risk of gearbox main shaft deformation. Furthermore, the height difference design between the end face of the pressing column 110 and the shaft end 128 allows the pressure-applying component to contact only the end face of the pressing column 110 or only the end face of the shaft end 128 during the initial stage of pressure application. When the end face of the extrusion column 110 is high, the pressure-applying component contacts the end face of the extrusion column 110, causing the first retaining plate 102 to move, thereby preferentially pressing out the wheel-side bearing 104. When the end face of the extrusion column 110 is flush with the end face of the shaft end 128, the pressure-applying component contacts the end face of the shaft end 128, causing the second retaining plate 106 to move, thus pressing out the gear-side bearing, thereby improving the disassembly efficiency of the gearbox bearing. Conversely, if the end face of the extrusion column 110 is low, the pressure-applying component preferentially contacts the end face of the shaft end 128 during the pressure process. The pressure-applying component causes the second retaining plate 106 to move, preferentially pressing out the gear-side bearing. When the end face of the shaft end 128 is flush with the end face of the extrusion column 110, the pressure-applying component contacts the end face of the extrusion column 110, causing the first retaining plate 102 to move, thus pressing out the wheel-side bearing.

[0039] Please continue reading Figure 1 The gearbox bearing disassembly device provided in this embodiment of the utility model has a core structure that unfolds around the support base 100, and achieves efficient disassembly of the bearing through modular design.

[0040] The support base 100 serves as the basic frame of the gearbox bearing disassembly device. The support base 100 is cast from high-strength materials (such as alloy steel) and has anti-slip textures or anti-slip pads on the bottom to ensure stable support of the gearbox bearing disassembly device during disassembly.

[0041] The support 100 has an internal cavity designed to accommodate the bearing components of the wheel side bearing 104 that are removed during disassembly.

[0042] The first snap-fit ​​plate 102 is mounted on the support base 100. A snap-fit ​​groove matching the outer ring of the wheel-side bearing 104 is provided on the surface of the first snap-fit ​​plate 102. The side of the first snap-fit ​​plate 102 facing the bottom of the support base 100 is used to snap the wheel-side bearing 104. Along the height direction of the support base 100, a second snap-fit ​​plate 106 is disposed above the first snap-fit ​​plate 102 and overlaps the support base 100. The side of the second snap-fit ​​plate 106 facing away from the first snap-fit ​​plate 102 is used to snap the motor-side bearing 108.

[0043] At least two extrusion columns 110 are provided, and the at least two extrusion columns 110 are arranged vertically along the center line of the support base 100, and the at least two extrusion columns 110 are parallel to each other. The first end of the extrusion column 110 (i.e., as shown in the figure) Figure 1 The lower end of the extrusion column 110 shown can be threaded to the first snap-fit ​​plate 102 to ensure that the extrusion column 110 can move synchronously with the first snap-fit ​​plate 102 in the vertical direction of the center line of the support base 100.

[0044] The second end of the extrusion column 110 (i.e., as shown) Figure 1 A height difference is formed between the upper end of the extrusion column 110 (as shown) and the shaft end 128 of the gearbox. It is understood that the second end of the extrusion column 110 can be configured as follows: Figure 1 The form shown above the shaft end 128 of the gearbox can also be configured such that the second end of the extrusion column 110 is below the shaft end 128 of the gearbox.

[0045] The pressure-applying component (not shown in the figure) can be a hydraulic cylinder or a press, and is mounted directly above the extrusion column 110. Initially, the pressure-applying component can only contact one of the second end and the shaft end 128 of the extrusion column 110.

[0046] Taking the second end of the extrusion column 110 being higher than the shaft end 128 as an example, when the pressure member presses down, the pressure member first contacts the second end of the extrusion column 110. As the pressure member continues to apply pressure, it can drive the extrusion column 110 to move downward, and then drive the first locking plate 102 to move through the extrusion column 110. Since the second locking plate 106 abuts against the support seat 100, the wheel side bearing 104 will be disassembled under the drive of the first locking plate 102. When the second end of the extrusion column 110 is flush with the shaft end 128, the pressure member can apply pressure to both the extrusion column 110 and the shaft end 128 at the same time. As the pressure member continues to apply pressure, since the second locking plate 106 remains stationary, the motor side bearing 108 can be disassembled.

[0047] Taking the second end of the extrusion column 110 being lower than the shaft end 128 as an example, when the pressure member presses down, the pressure member first contacts the shaft end 128. As the pressure member continues to apply pressure, it can drive the gear shaft to move downward. Since the second snap plate 106 is fixed, the motor side bearing 108 will be removed first. When the shaft end 128 is flush with the second end of the extrusion column 110, the pressure member can apply pressure to both the shaft end 128 and the extrusion column 110 at the same time. As the pressure member continues to apply pressure, the wheel side bearing 104 can be removed because the extrusion column 110 is continuously pressed down.

[0048] According to one embodiment of the present invention, a pad 112 is also included, which is used for detachably mounting on the end of the shaft end 128 facing the pressure member.

[0049] In one embodiment of this utility model, the pad 112 may be frustum shaped, and the pad 112 may be detachably installed on the shaft end 128 by means of threaded connection; or the pad 112 may adopt an adhesive structure, and in actual use, the pad 112 may be directly glued to the shaft end 128.

[0050] The use of threaded or adhesive connections facilitates quick installation and removal of the pad 112. Different thicknesses of pads 112 can be flexibly selected to fit the actual height difference between the shaft end 128 and the pressure-applying component, ensuring that the pressure-applying component accurately and effectively applies pressure to the shaft end 128 or the second end of the extrusion column 110, thus improving the versatility and applicability of the device. Furthermore, the pad 112 prevents damage to the extrusion column 110 during pressure application, effectively guaranteeing its service life.

[0051] According to one embodiment of the present invention, an elastic recovery member 114 is sleeved on the extrusion column 110, and the two ends of the elastic recovery member 114 abut against the second end of the extrusion column 110 and the second snap-fit ​​plate 106.

[0052] In one embodiment of this utility model, the elastic recovery member 114 can be a high-strength helical spring, the inner diameter of which is slightly larger than the outer diameter of the extrusion column 110, and it is tightly fitted onto the extrusion column 110. The two ends of the spring are in close contact with the boss at the second end of the extrusion column 110 and the bottom surface of the second snap-fit ​​plate 106, respectively. Alternatively, an elastic washer made of rubber can be used as the elastic recovery member 114. The washer has a hole in the middle, the hole diameter of which is adapted to the outer diameter of the extrusion column 110, and the thickness of the washer is selected according to the required elastic support force.

[0053] A helical spring or rubber elastic washer can provide cushioning during the pressure application process, preventing damage to the bearing, extrusion column 110 and second snap plate 106 caused by excessive impact force generated during the pressure application. At the same time, after the pressure is applied and the external force is removed, the elastic recovery member 114 can quickly reset the extrusion column 110, which is convenient for the next operation and improves the service life and operating efficiency of the device.

[0054] According to one embodiment of the present invention, a limiting member 116 is provided at the second end of the extrusion column 110, and the two ends of the elastic recovery member 114 abut against the limiting member 116 and the second snap plate 106.

[0055] In one embodiment of this utility model, the limiting member 116 can be a nut, with an external thread provided at the second end of the extrusion column 110. By tightening the nut, the elastic recovery member 114 is pressed between the nut and the second snap-fit ​​plate 106; or the limiting member 116 can be an annular boss welded to the second end of the extrusion column 110, with the outer diameter of the boss being larger than the inner diameter of the elastic recovery member 114, and the elastic recovery member 114 is installed between the boss and the second snap-fit ​​plate 106.

[0056] The nut or annular boss acts as a limiting element 116, which can effectively prevent the elastic recovery element 114 from axial displacement during the pressure application process, ensuring that the elastic recovery element 114 always plays a stable role in buffering and resetting, thus guaranteeing the stability and reliability of the device structure.

[0057] According to one embodiment of the present invention, a through hole is provided on the second snap plate 106, and the extrusion post 110 passes through the through hole.

[0058] In one embodiment of this utility model, the through hole is circular, and its diameter is about 1 to 2 millimeters larger than the outer diameter of the extrusion column 110, so as to ensure that the extrusion column 110 can pass through the through hole smoothly without excessive shaking; a friction-reducing bushing can also be provided on the inner wall of the through hole. The friction-reducing bushing can be made of a material with a low coefficient of friction such as polytetrafluoroethylene to reduce the friction between the extrusion column 110 and the through hole.

[0059] The appropriate through-hole diameter and friction-reducing bushing configuration make the extrusion column 110 move more smoothly during up and down movement, reducing the impact of friction on the pressure application effect. At the same time, it reduces the wear of the extrusion column 110 and the second snap plate 106, improving the accuracy and service life of the device.

[0060] According to one embodiment of the present invention, a first receiving groove 118 is provided on the first snap-fit ​​plate 102, the shape of which is adapted to the shape of the wheel side bearing 104; a second receiving groove 120 is provided on the second snap-fit ​​plate 106, the shape of which is adapted to the shape of the motor side bearing 108.

[0061] In one embodiment of this utility model, the first receiving groove 118 and the second receiving groove 120 are both semi-circular grooves. The radii of the first receiving groove 118 and the second receiving groove 120 are equal to the outer diameter of the corresponding bearing. Furthermore, several anti-slip protrusions can be provided at the bottom of the first receiving groove 118 and the second receiving groove 120 to increase the friction with the corresponding bearing. The depth of the first receiving groove 118 and the second receiving groove 120 can be set to one-third to one-half of the thickness of the corresponding bearing, which can ensure the stability of the installation of the corresponding bearing and facilitate the disassembly of the corresponding bearing.

[0062] The receiving groove and anti-slip protrusions that are adapted to the shape of the bearing enable the wheel-side bearing 104 and the motor-side bearing 108 to be quickly positioned during installation and remain stable during disassembly, preventing the bearing from shifting or rotating on the snap-fit ​​plate, thus improving the accuracy and safety of bearing disassembly.

[0063] According to one embodiment of the present invention, a first mounting groove is provided on the edge of the first snap-fit ​​plate 102, and the wheel-side bearing 104 is adapted to be mounted on the first snap-fit ​​plate 102 through the first mounting groove; a second mounting groove is provided on the edge of the second snap-fit ​​plate 106, and the motor-side bearing 108 is adapted to be mounted on the second snap-fit ​​plate 106 through the second mounting groove.

[0064] In one embodiment of this utility model, both the first mounting groove and the second mounting groove can be configured as U-shaped grooves. The width of the U-shaped groove is smaller than the outer ring diameter of the corresponding bearing. When it is necessary to install the wheel-side bearing 104 onto the first snap-fit ​​plate 102, the first snap-fit ​​plate 102 can be directly inserted into the side of the wheel-side bearing 104 facing the motor-side bearing 108 by means of insertion. Similarly, when it is necessary to install the motor-side bearing 108 onto the second snap-fit ​​plate 106, the second snap-fit ​​plate 106 can be directly inserted into the side of the motor-side bearing 108 facing the wheel-side bearing 104 by means of insertion.

[0065] The design of the first and second mounting slots facilitates the installation and removal of the corresponding bearings. Operators can accurately install the bearings onto the snap-fit ​​plate without complicated operations, thus improving work efficiency.

[0066] According to one embodiment of the present invention, a third snap-fit ​​plate 122 is also included. The third snap-fit ​​plate 122 is disposed on the side of the first snap-fit ​​plate 102 facing the second snap-fit ​​plate 106. During the pressing process of the pressure-applying component, the third snap-fit ​​plate 122 is used to snap the drive gear.

[0067] In one embodiment of this utility model, the third snap-fit ​​plate 122 is generally U-shaped, and its inner diameter is adapted to the outer diameter of the extrusion column 110. In the actual disassembly process, the third snap-fit ​​plate 122 is disposed on the side of the first snap-fit ​​plate 102 facing the second snap-fit ​​plate 106. The function of the third snap-fit ​​plate 122 is to prevent the driving gear from being pressed out synchronously with the first snap-fit ​​plate 102 when disassembling the wheel side bearing 104 and the motor side bearing 108, in order to facilitate the removal of the driven gear.

[0068] The third locking plate 122 can tightly lock the drive gear, and during the pressure application process, the drive gear and the bearing are subjected to force synchronously, which prevents the drive gear from rotating or displacing during disassembly, ensuring the smooth progress of disassembly work, improving the accuracy and efficiency of disassembly, and facilitating the disassembly of the driven gear.

[0069] According to one embodiment of the present invention, a limiting platform 124 is provided on the support base 100. During the pressure application process of the pressure-applying component, the limiting platform 124 is adapted to cooperate with the third snap-fit ​​plate 122 to limit the removal of the drive gear.

[0070] In one embodiment of the present invention, the limiting platform 124 can be a rectangular boss and is disposed on the support base 100. The limiting platform 124 is disposed on the support base 100 on the side of the first snap-fit ​​plate 102 away from the third snap-fit ​​plate 122.

[0071] In addition, a rubber buffer pad can be provided on the surface where the limiting platform 124 and the third snap plate 122 contact each other to reduce rigid collisions between them.

[0072] The limiting action of the limiting platform 124 and the third locking plate 122 accurately controls the travel of the drive gear, preventing damage during disassembly due to excessive pressure. The rubber buffer pad acts as a buffer, reducing the impact force during disassembly and protecting the drive gear and other components of the device. It is understood that when the pressure-applying component moves the extrusion column 110 and the gearbox shaft downwards, the limiting action of the limiting platform 124 prevents the third locking plate 122 from continuing to move downwards. With continued pressure from the pressure-applying component, the driven gear can be accurately disassembled.

[0073] According to one embodiment of the present invention, a positioning member 126 is provided on the support base 100, and along the height direction of the support base 100, the third snap-fit ​​plate 122 is adapted to limit the relative position with the support base 100 by the positioning member 126.

[0074] In one embodiment of this utility model, the positioning member 126 can be two guide posts arranged radially along the support base 100. When the first locking plate 102 moves upward under the elastic restoring force of the elastic restoring member 114, the contact between the first locking plate 102 and the third locking plate 122 can synchronously drive the third locking plate 122 to move upward. When the third locking plate 122 contacts the positioning member 126, the third locking plate 122 can prevent the third locking plate 122 from continuing to move upward, thereby providing an accurate installation position for the subsequent disassembly process.

[0075] The guide post or positioning pin serves as the positioning element 126, which can precisely define the position of the third snap plate 122 on the support base 100, ensuring that the drive gear is always in the correct position during disassembly, thereby improving the accuracy and stability of disassembly and avoiding disassembly failure or component damage due to positional deviation of the third snap plate 122.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
