Description

Technical Field

[0001] This utility model belongs to the technical field of bearing disassembly devices, specifically relating to a bearing disassembly device for a hydraulic motor. Background Technology

[0002] Hydraulic motors, as key devices converting hydraulic energy into mechanical energy, are widely used in engineering machinery, shipbuilding, aerospace, and other fields. During the long-term use of hydraulic motors, bearings, as their core supporting components, require periodic replacement or maintenance due to wear and fatigue. However, hydraulic motor bearings are typically installed in relatively compact spaces and have tight fits with shafts, housings, and other components, making disassembly difficult. Existing bearing disassembly methods mainly include hammering and pulling. Hammering involves manually striking the outer ring of the bearing with tools such as hammers, using impact force to remove the bearing from the shaft. However, this method easily damages the bearing and shaft, is physically demanding for operators, and has low disassembly efficiency. Pulling typically uses specialized pullers, employing threaded connections or hydraulic stretching to remove the bearing. However, existing pullers are complex in structure, inconvenient to operate, have poor adaptability to different bearing specifications, and are prone to slippage and bearing damage during disassembly. Therefore, bearing removal devices for disassembling hydraulic motors have emerged. For example, Chinese patent publication number "CN 215748956 U" discloses a bearing removal device for hydraulic motors. This device, through the design of a bracket, connecting cylinder, and crossbar, allows for adjustment of the device's angle and position according to the location of the bearing being disassembled. Simultaneously, the portion above the crossbar can be directly removed for operation, improving portability. While this device can disassemble the motor, it is inconvenient to secure it, requiring manual fixation, resulting in low fixing efficiency for hydraulic motors. Furthermore, the device's cylindrical structure limits its application, making it unsuitable for adjusting to bearing specifications. Additionally, the bearing may fall directly after being pushed, potentially causing excessive damage and hindering bearing recycling. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 As shown, this utility model provides the following technical solution:

[0028] A bearing disassembly device for a hydraulic motor includes a fixing component 1 and a disassembly component 3. The fixing component 1 includes a support portion, on which two lead screws 16 are symmetrically rotatably connected. A movable moving plate 17 is sleeved between the two lead screws 16. A positioning frame 18 is fixedly connected to one side of the moving plate 17 and the inner wall of the support portion. A fixed cavity that abuts against the hydraulic motor is formed between the two positioning frames 18. The disassembly component 3 includes a pushing portion for pushing the bearing and a telescopic portion for driving the pushing portion to reciprocate. Two through holes 14 are formed horizontally on the support portion. The fixed cavity is located between the two through holes 14. The pushing portion moves horizontally between the two through holes 14.

[0029] With the above technical solution, when personnel need to disassemble the bearing of the hydraulic motor, the hydraulic motor to be fixed is placed between two positioning frames 18. The screw 16 on the support part rotates, thereby causing the moving plate 17 to move along the length direction of the two screws 16. When the moving plate 17 moves, it will synchronously drive one of the positioning frames 18 to move, causing the positioning frame 18 to move towards the other positioning frame 18 until the two positioning frames 18 clamp the hydraulic motor. After the hydraulic motor is fixed, the telescopic part works, causing the telescopic part to drive the pushing part to move, so that the pushing part enters through one of the through holes 14. The pushing part pushes the bearing inside the hydraulic motor, causing the bearing to be discharged from the other through hole 14, thereby completing the disassembly of the bearing.

[0030] Specifically, in one embodiment, regarding the aforementioned pushing portion, as... Figures 1-3 and Figure 6 As shown, the pushing part includes a side rod 34, one end of which is fixedly connected to a tapered rod 35, which gradually tapers from one end near the side rod 34 to the other end.

[0031] In this embodiment, after the bearing is fixed, the telescopic part works to drive the side rod 34 to move, which in turn drives the tapered rod 35 to move. The tapered rod 35 pushes the bearing in the hydraulic motor, thereby separating the bearing from the hydraulic motor and completing the disassembly of the bearing. When disassembling the bearing through the tapered rod 35, the device can be adjusted according to the bearing specifications, thus improving the applicability of the device.

[0032] Furthermore, in this utility model, regarding the aforementioned telescopic portion, as follows: Figures 1-3 As shown, the telescopic part includes a top plate 36, which is fixedly connected to the top of the support part, and an electric push rod 32 is fixedly connected to the bottom of the top plate 36. The telescopic end of the electric push rod 32 is connected to a telescopic rod 33, and a connecting plate 31 is fixedly connected between the free end of the telescopic rod 33 and the free end of the side rod 34.

[0033] In this embodiment, the top plate 36 is supported by the support portion, and the electric push rod 32 is supported by the top plate 36. After the hydraulic motor is fixed, the electric push rod 32 works, thereby driving the telescopic rod 33 to move. The telescopic rod 33 drives the connecting plate 31 to move, and the connecting plate 31 drives the tapered rod 35 to move, so that the tapered rod 35 pushes the bearing in the hydraulic motor, thereby completing the disassembly of the bearing.

[0034] Specifically, in one embodiment, regarding the aforementioned support portion, as... Figures 1-4 As shown, the support part includes a base frame 11, and a plurality of feet 12 for supporting itself are fixedly connected to the bottom of the base frame 11. Through holes 14 are horizontally opened on the base frame 11.

[0035] In this embodiment, the base frame 11 is fixed by the base foot 12, and the lead screw 16 is supported by the base frame 11. When it is necessary to drive the moving plate 17 to move, the moving plate 17 can be moved along the lead screw 16 by rotating the lead screw 16.

[0036] After the bearing of the hydraulic motor is removed, in order to facilitate the removal of the hydraulic motor, such as... Figures 1-4 As shown, the bottom of the base frame 11 has a through bottom hole 13, which is located between multiple feet 12.

[0037] In this embodiment, after the bearing on the hydraulic motor is disassembled, the lead screw 16 is reversed, thereby driving the moving plate 17 to move. The moving plate 17 drives one of the positioning frames 18 away from the other positioning frame 18, thereby allowing the hydraulic motor to be disassembled. The hydraulic motor after the bearing is disassembled is discharged from the bottom hole 13, completing the collection of the hydraulic motor.

[0038] Furthermore, regarding how the lead screw 16 rotates in this utility model, as follows: Figures 1-4As shown, a motor 15 is fixedly connected to the base frame 11, and the output end of the motor 15 is connected to one of the lead screws 16.

[0039] In this embodiment, when it is necessary to drive the lead screw 16 to rotate, the motor 15 is activated to drive the lead screw 16 to rotate, thereby making the moving plate 17 easy to move.

[0040] Furthermore, after the hydraulic motor is discharged from the bottom hole 13, in order to facilitate the collection of the hydraulic motor, such as... Figures 1-5 As shown, a storage component 2 is fixedly connected to the bottom of the base frame 11. The top of the storage component 2 is open to form a storage cavity 23 for storing the hydraulic motor. The storage cavity 23 is connected to the bottom hole 13.

[0041] In this embodiment, after the hydraulic motor is discharged from the bottom hole 13, it is received by the storage cavity 23 on the storage component 2, making it easy to collect the hydraulic motor.

[0042] Specifically, in one embodiment, regarding the aforementioned storage component 2, as... Figures 1-3 and Figure 5 As shown, the storage component 2 includes a storage box 21. One side of the storage box 21 is open to form a side groove 22, and a storage cavity 23 is formed on the top of the storage box 21. The storage cavity 23 is connected to the side groove 22. The bottom of the storage cavity 23 is inclined to form a ramp 24. The horizontal height of the ramp 24 near the side groove 22 is lower than the horizontal height of the other side.

[0043] In this embodiment, the hydraulic motor is received by the storage cavity 23 on the storage box 21, and the hydraulic motor is discharged through the side groove 22 by the ramp 24, so that the hydraulic motor can be easily collected and discharged, reducing the difficulty of collecting the hydraulic motor.

[0044] After the bearing is disassembled, in order to guide the bearing out, such as Figures 1-3 , Figures 7-8 As shown, a guide member 4 is fixedly connected to the side of the base frame 11 away from the connecting plate 31. The guide member 4 includes a guide frame 41, the top of which is open to form a guide cavity 42, which is connected to the through hole 14.

[0045] In this embodiment, after the bearing is disassembled, it is received by the guide cavity 42 on the guide frame 41 and guided to be discharged in a concentrated manner through the guide cavity 42.

[0046] When the bearing is discharged from the guide chamber 42, in order to reduce the kinetic energy of the bearing during its fall, such as Figures 7-8 As shown, rubber plates 43 are fixedly connected to both sides of the inner wall of the feed chamber 42 along its own length direction, and multiple rubber plates 43 are arranged alternately.

[0047] In this embodiment, when the bearing is discharged through the guide cavity 42, multiple rubber plates 43 cooperate to prevent the bearing from sliding down directly, thereby reducing the kinetic energy of the bearing during the falling process and avoiding excessive damage to the bearing.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
