Description

Technical Field

[0001] This invention relates to the field of motor pulley technology, and in particular to a method and apparatus for decoupling a power pulley. Background Technology

[0002] Motor pulleys, belonging to the hub category, are crucial components for power transmission in motors. During long-term operation, motor pulleys are susceptible to wear, cracks, or localized damage due to friction, vibration, and environmental factors. Traditional disassembly methods for damaged pulleys rely on manual labor using various tools, which is not only laborious and time-consuming but also prone to secondary damage to the drive shaft and other related components, potentially even posing safety hazards. Especially in confined spaces or complex equipment installation locations, manual disassembly is often difficult, resulting in extremely low efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the problems of traditional manual disassembly of damaged pulleys, which is laborious, time-consuming, prone to component damage, poses safety hazards, and is particularly inefficient in confined and complex environments. The invention proposes a power pulley decoupling method and device.

[0004] On one hand, this application provides a power pulley decoupling device, including a motor, an output shaft and a pulley mounted on the output shaft, and further including: a support base disposed at the bottom of the motor, one end of the support base being connected to a connecting plate, and a pair of support rods fixedly connected to the side of the connecting plate away from the support base; a pair of retaining rings sleeved on the motor, the retaining rings being provided with a sliding mechanism for moving the motor horizontally; and a pair of support plates fixedly connected to the middle of the support rods, the support plates being provided with a pushing mechanism for disengaging the pulley from the output shaft.

[0005] Optionally, the sliding mechanism includes a U-shaped frame fixedly connected to the retaining ring, a limiting rod fixedly connected inside the U-shaped frame, a return spring movably sleeved on the limiting rod, a pair of support blocks fixedly connected to the upper surface of the support and slidably sleeved with the corresponding limiting rod, one end of the return spring fixedly connected to the inner wall of the U-shaped frame, and the other end of the return spring fixedly connected to the support block.

[0006] Optionally, the pushing mechanism includes a pair of support rods, with a pair of support plates fixedly connected inside the support rods. Each support plate has a slot, and a cylinder is fixedly connected inside the slot. The end of the output shaft away from the motor has a T-shaped slot, and a T-shaped pin is engaged inside the T-shaped slot. The pulley has a mounting hole in the middle that is movably connected to the output shaft. The mounting hole has a positioning groove engaged by the T-shaped pin. The pulley has multiple belt grooves arranged linearly to hold the belt.

[0007] Optionally, the top of the support has an arc-shaped groove that fits tightly against the retaining ring and allows it to slide.

[0008] Optionally, an end frame is fixedly connected to one end of the pair of support rods away from the connecting plate, and support legs are fixedly connected to the bottom of both ends of the end frame.

[0009] Optionally, the top of the end frame is fixedly connected with a plurality of reinforcing plates arranged in a linear pattern.

[0010] Optionally, the side of the connecting plate near the pulley is bolted to a mounting base, and the side of the mounting base away from the connecting plate is fixedly connected to a retaining sleeve that abuts against the retaining ring.

[0011] Optionally, a tray that receives the pulley is fixedly connected to the side of the connecting plate away from the support, and an arc-shaped groove is provided on the top of the tray.

[0012] On the other hand, this application provides a decoupling method for a power pulley decoupling device, applied to a power pulley decoupling device as described above, comprising the following steps:

[0013] S1. When a thrust is applied to the output shaft to start disassembling the pulley, the cylinder is activated, and its piston rod pushes the output shaft so that the pulley abuts against the end of the ferrule.

[0014] S2. When the pulley and output shaft are separated and the old pulley is collected, the output shaft continues to move and disengage from the pulley. The pulley falls onto the piston rod, and after the cylinder retracts, it falls into the tray.

[0015] S3. When the cylinder is reset and ready to install the new pulley, until the motor output shaft is no longer under force, the U-shaped bracket, under the action of the reset spring, drives the retaining ring and the motor to reset.

[0016] S4. When the new pulley is replaced, simply install the new pulley onto the output shaft to restore the function.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] This invention, through the design of a motor, pulley, connecting plate, support rod, sliding mechanism, and pushing mechanism, enables pulley disassembly to be completed by cylinder drive, replacing manual operation. This not only allows for rapid pulley removal and improves disassembly efficiency but also avoids hard contact between components, reducing the risk of damage. The automated operation keeps personnel away from the disassembly site, ensuring safety. Finally, its compact structure allows for efficient operation even in confined and complex environments, effectively solving the problems of traditional disassembly methods, such as being labor-intensive and time-consuming, having easily damaged components, posing safety hazards, and having poor environmental adaptability.

[0032] Example

[0033] like Figures 1 to 6As shown, the present invention proposes a power pulley decoupling device, including a motor 9, an output shaft 91 on the motor 9, and a pulley 94 mounted on the output shaft 91. A retaining sleeve is fixedly fitted on the output shaft 91, and the retaining sleeve is positioned between the pulley 94 and the retaining sleeve 71. Its function is that after the cylinder 62 presses against the output shaft 91, the force applied to the output shaft 91 is distributed to one end of the entire motor 9, preventing damage to the internal components of the motor from the piston rod of the cylinder 62 pressing against the output shaft 91. A support 3 is provided at the bottom of the motor 9. The top of the support 3 has an arc-shaped groove 31 that fits tightly against and allows the retaining ring 4 to slide. The arc-shaped groove 31 supports the sliding of the retaining ring 4. A connecting plate 2 is connected to one end of the support 3. A tray 8 that catches the pulley 94 is fixedly connected to the side of the connecting plate 2 away from the support 3. The tray 8 is installed directly below the pulley 94. When the piston rod of the cylinder 62 retracts, the pulley 94 completely disengages from the piston rod and falls into the tray 8. The top of the tray 8 has an arc-shaped groove. The arc-shaped groove is designed to prevent the pulley 94 from wobbling when it falls into it. Its shape is used to lock the pulley 94 in place, ensuring that it can be locked after falling in. A pair of support rods 1 are fixedly connected to the side of the connecting plate 2 away from the support 3. A pair of retaining rings 4 are fitted on the motor 9. A pair of support plates 6 are fixedly connected to the middle of the support rods 1.

[0034] In addition, such as Figure 1 , Figure 2 and Figure 4 As shown, the retaining ring 4 is provided with a sliding mechanism that allows the motor 9 to move horizontally. The sliding mechanism includes a U-shaped frame 41 fixedly connected to the retaining ring 4. A limit rod 42 is fixedly connected inside the U-shaped frame 41. A return spring 43 is movably sleeved on the limit rod 42. A pair of support blocks 44 that are slidably sleeved with the corresponding limit rods 42 are fixedly connected to the upper surface of the support 3. One end of the return spring 43 is fixedly connected to the inner wall of the U-shaped frame 41, and the other end of the return spring 43 is fixedly connected to the support block 44.

[0035] It is worth noting that, such as Figures 2 to 6As shown, the support plate 6 is equipped with a pushing mechanism that disengages the pulley 94 from the output shaft 91. The pushing mechanism includes a pair of support rods 1, with a pair of support plates 6 fixedly connected inside the support rods 1. Each support plate 6 has a slot 61, which is fixedly connected to a cylinder 62. The cylinder 62 is fixedly connected inside the slot 61. A T-shaped slot 92 is provided at the end of the output shaft 91 away from the motor 9. A T-shaped pin 93 is engaged inside the T-shaped slot 92. The T-shaped pin 93 is used to hold the pulley 94 installed inside the output shaft 91, ensuring that the output shaft 91 can drive the pulley 94 after rotation without slippage. A mounting hole 95 is provided in the middle of the pulley 94, which is movably fitted with the output shaft 91. A positioning groove 96 is provided inside the mounting hole 95, which is engaged by the T-shaped pin 93. The positioning groove 96 and the T-shaped pin 93 engage with each other, thereby ensuring that the output shaft 91 can drive the pulley 94 after rotation without slippage. The pulley 94 has multiple linearly arranged belt grooves 941 for securing the belt. As a key component for fixing the pulley, the belt grooves 941 are designed to ensure sufficient and uniform contact area when fixing the belt, thereby enhancing the fixing effect and reducing secondary damage to the pulley caused by uneven local stress.

[0036] Furthermore, such as Figure 1 As shown, an end frame 5 is fixedly connected to the end of a pair of support rods 1 away from the connecting plate 2. Multiple linearly arranged reinforcing plates 51 are fixedly connected to the top of the end frame 5. The reinforcing plates 51 significantly improve the overall strength of the support by increasing the load-bearing area and dispersing stress. Simultaneously, they effectively limit the relative displacement of the end frame 5 components, enhancing the stability of the support. Furthermore, they help the end frame 5 better distribute the load it bears, avoiding excessive local loads. Support legs 52 are fixedly connected to the bottom of both ends of the end frame 5.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the side of the connecting plate 2 near the pulley 94 is bolted to a mounting base 7. The side of the mounting base 7 away from the connecting plate 2 is fixedly connected to a retaining sleeve 71 that abuts against the retaining ring 4. The retaining sleeve 71 is used to hold the pulley 94, ensuring that the pulley 94 can be easily, safely and quickly disassembled.

[0038] This application provides a decoupling method for a power pulley decoupling device, such as... Figure 1 - Figure 6 As shown, it includes the following steps:

[0039] S1. When a thrust is applied to the output shaft 91 and the pulley 94 begins to disassemble, the cylinder 62 is activated, and its piston rod pushes the output shaft 91 so that the pulley 94 abuts against the end of the sleeve 71.

[0040] S2. When the pulley 94 and the output shaft 91 are separated and the old pulley 94 is collected, the output shaft 91 continues to move and disengages from the pulley 94. The pulley 94 falls to the piston rod, and after the cylinder 62 retracts, it falls into the tray 8.

[0041] S3. When the cylinder 62 is reset and ready to install the new pulley 94, until the output shaft of the motor 9 is no longer under force, the U-shaped bracket 41 drives the retaining ring 4 and the motor 9 to reset under the action of the reset spring 43.

[0042] S4. When the new pulley 94 is replaced, simply install the new pulley 94 onto the output shaft 91 to restore the function.

[0043] In this embodiment, when it is necessary to quickly remove the pulley 94 from the output shaft 91, simply activate the cylinders 62 on the pair of trays 6. After the cylinders 62 are activated, the piston rod pushes the output shaft 91, which in turn drives the motor 9 and the pair of retaining rings 4 to slide within the arc-shaped groove 31. As the output shaft 91 moves, it also drives the pulley 94 to move until the pulley 94 abuts against the end of the retaining sleeve 71. At this point, the output shaft 91 continues to move until it is completely disengaged from the mounting hole 95 in the pulley 94. Then, the pulley 94 falls down onto the piston rod of the cylinder 62 due to gravity, and the cylinder 62 retracts the piston rod, allowing the pulley 94 to fall into the tray 8 for workers to handle.

[0044] When the piston rod of cylinder 62 abuts against the output shaft 91, causing it to disengage from the pulley 94, a pair of retaining rings 4 simultaneously drive a pair of U-shaped brackets 41 to move. The U-shaped brackets 41 then drive the internal limiting rod 42 to slide along the support block 44. This continues until the output shaft 91 is no longer abutted by the piston rod of cylinder 62. At this point, the U-shaped brackets 41, through the elastic thrust of the return spring 43, cause the retaining rings 41 and the internal motor 9 to slide back to their original positions along the arc groove 31. Finally, the new pulley 94 is installed on the output shaft 91, ensuring safety, speed, and efficiency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
