Description

Technical Field

[0001] This utility model relates to the field of automotive utility tools, specifically to a belt mounting device. Background Technology

[0002] With the continuous development of automotive engine technology, more and more automotive engines are beginning to use elastic belts. Elastic belts can reduce the number of tensioner parts while ensuring functionality.

[0003] However, since the single-strand belt used is a wear part, it needs to be replaced after a certain period of use in order to ensure engine performance.

[0004] Because elastic belts have a certain degree of elasticity, they are tightly installed on the pulleys to ensure the stability of transmission between them and prevent slippage. Therefore, belts are typically assembled using belt mounting devices.

[0005] Currently, commonly used belt mounting devices include a main body and a first limiting part and a second limiting part. The main body has a mounting surface, and the first and second limiting parts are arranged parallel to each other and spaced apart on the mounting surface of the main body. In use, the first and second limiting parts are respectively secured to both sides of the pulley to ensure that the belt mounting device is stably fixed to the pulley when installing the belt.

[0006] However, the structure is complex and requires fixing of the first and second limiting parts, making operation complicated. This belt mounting device is only suitable for working conditions where there is installation space on both sides of the pulley, and its application range is limited. Utility Model Content

[0007] The purpose of this invention is to at least solve some of the problems mentioned above.

[0008] To achieve this objective, the present invention provides a belt mounting device, comprising:

[0009] The body has a bearing surface and a mounting surface, the mounting surface being configured to abut against the outer peripheral surface of the pulley, and the bearing surface being configured to support the belt;

[0010] A fixing part, which is connected to the body at an angle, is configured to constrain the axial displacement of the body along the pulley; and

[0011] A limiting protrusion is connected to the body. The limiting protrusion has a first limiting surface, which is configured to drive the belt to mesh with the pulley when the pulley rotates.

[0012] This belt mounting device only requires a fixing part to limit the position of the main body, without the need for other structures to fix the main body to both sides of the pulley. The structure is simple and easy to operate, and the simplified structure helps to reduce the weight of the belt mounting device, making it easy to carry.

[0013] In use, the belt mounting device is fixed on the pulley, so that the bearing surface abuts against the outer circumferential surface of the pulley. Then, a portion of the belt is fitted onto the bearing surface. At this time, the pulley rotates mechanically, and the first limiting surface can gradually install the belt to be installed onto the pulley, realizing the engagement of the belt and the pulley, which helps to reduce the labor intensity of maintenance personnel.

[0014] Compared to belt mounting devices that need to be fixed to both sides of the pulley, the belt mounting device of this embodiment only needs to be fixed to one side of the pulley. It can be applied to working conditions where the pulley installation space is narrow or the pulley only has installation space on one side, which helps to expand the applicability of the belt mounting device.

[0015] In some embodiments, the fixing part is configured to abut against the second limiting surface of the pulley, and the fixing part is provided with a first fixing hole for fixed connection with the second limiting surface.

[0016] When installing the belt, simply use fasteners to pass through the first and second fixing holes to connect the belt mounting device and the pulley to fix the belt mounting device. This prevents the belt mounting device from falling off during the limiting protrusion's belt-limiting process, thus improving the stability during use.

[0017] In some embodiments, there is one first fixing hole.

[0018] Maintenance personnel only need to operate one fastener to fix the belt mounting device to the pulley for easy belt installation. This method is simple to operate, reduces the workload of maintenance personnel, improves maintenance efficiency, and reduces maintenance costs.

[0019] In some embodiments, the cross-sections of the body and the fixing part are arc-shaped, and the central angles corresponding to the arc-shaped body and the fixing part are between 15° and 40°.

[0020] This structure helps to ensure that the circumferential curvature of the belt mounting device along the pulley is small, which helps to reduce the weight of the belt mounting device, making it easier to carry, operate and install, and thus reducing the cost of the belt mounting device.

[0021] In some embodiments, the central angle corresponding to the arc-shaped body and the fixing part is 20°.

[0022] This angle reduces the size of the belt mounting device, which helps to reduce its weight and ensures its structural stability.

[0023] In some embodiments, the fixing part has at least one weight-reducing inclined surface, an inner ring surface, and a side surface. The inner ring surface is the end face of the fixing part facing the pulley, and the two sides of the fixing part along the circumference of the pulley are the side surfaces. The weight-reducing inclined surface is inclined from the inner ring surface to the side surface.

[0024] Compared to the direct right-angle connection between the inner ring surface and the side surface, this fixing part reduces the weight of the belt installation device by removing some material, which in turn makes the belt installation device easier to carry, operate and install, and helps to reduce the cost of the belt installation device.

[0025] In some embodiments, the fixing part is a single-arm structure, so that a weight-reducing space is formed between the side of the fixing part away from the mounting surface and the body.

[0026] Compared to the direct right-angle connection between the inner ring surface and the side surface, this fixing part reduces the weight of the belt installation device by removing some material, which in turn makes the belt installation device easier to carry, operate and install, and helps to reduce the cost of the belt installation device.

[0027] In some embodiments, the limiting protrusion protrudes toward the side of the body away from the fixing part, and along the rotation direction of the pulley, the limiting protrusion gradually decreases in axial dimension along the pulley, so that the first limiting surface is an inclined surface.

[0028] During belt assembly, rotating the pulley gradually pushes the belt onto the pulley using the inclined surface of the first limiting surface, thus achieving belt-pulley engagement. After belt assembly, the maintenance personnel remove the fasteners. Rotating the pulley at this point, the belt's reaction force pushes the belt mounting device away from the pulley, causing it to detach. This process achieves disassembly of the belt mounting device through mechanical movement, resulting in lower labor intensity, higher accuracy, and eliminating the need for manual disassembly by maintenance personnel, thereby reducing their workload.

[0029] In some embodiments, the body, the fixing part, and the limiting protrusion are an integral structure.

[0030] The integrated structure helps improve the structural stability of the connection between the main body, the fixing part, and the limiting protrusion.

[0031] In some embodiments, the body has a weight-reducing groove located on the mounting surface and disposed near the fixing portion.

[0032] This belt installation device reduces its weight through a weight-reducing groove, making it easier to carry, operate, and install, and thus reducing its cost. Attached Figure Description

[0050] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0051] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. The terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0052] like Figure 1 and Figure 2 As shown, this embodiment provides a belt mounting device, which includes a body 1, a fixing part 10, and a limiting protrusion 12. The body 1 has a bearing surface 7 and a mounting surface 9. The mounting surface 9 is configured to abut against the outer peripheral surface of the pulley 2. The bearing surface 7 is configured to support the belt. The fixing part 10 is connected to the body 1 at an angle and is configured to constrain the axial displacement of the body 1 along the pulley 2. The limiting protrusion 12 is connected to the body 1 and has a first limiting surface 6. The first limiting surface 6 is configured to drive the belt to mesh with the pulley 2 when the pulley 2 rotates.

[0053] The belt mounting device only requires the fixing part 10 to limit the main body 1. No other structure is needed to fix the main body 1 to both sides of the pulley 2. The structure is simple and easy to operate. The simplified structure also helps to reduce the weight of the belt mounting device and makes it easy to carry.

[0054] In use, the belt mounting device is fixed on the pulley 2, so that the bearing surface 7 abuts against the outer circumferential surface of the pulley 2. Then, a portion of the belt is fitted onto the bearing surface 7. At this time, the pulley 2 rotates mechanically, and the first limiting surface 6 can gradually install the belt to be installed onto the pulley 2, so that the belt and the pulley 2 mesh, which helps to reduce the labor intensity of maintenance personnel.

[0055] Furthermore, compared to belt mounting devices that need to be fixed on both sides of the pulley 2, the belt mounting device of this embodiment only needs to be fixed on one side of the pulley 2. It can be applied to working conditions where the installation space of the pulley 2 is narrow or the pulley 2 only has installation space on one side, which helps to expand the applicability of the belt mounting device.

[0056] The main body 1 is an arc-shaped plate, which helps to reduce the overall weight of the belt mounting device while ensuring structural strength. At the same time, the mounting surface 9 of the arc-shaped main body 1 has at least two contact points with the outer peripheral surface of the pulley 2, which helps to ensure the stability of the belt mounting device when it is fixed on the pulley 2.

[0057] In some embodiments, such as Figure 3 and Figure 4 As shown, the fixing part 10 is configured to abut against the second limiting surface 4 of the pulley 2, and the fixing part 10 is provided with a first fixing hole 5 for fixed connection with the second limiting surface 4. A second fixing hole 3 may be provided on the first limiting surface 6. When installing the belt, the belt mounting device and the pulley 2 can be fixed by simply using fasteners passing through the first fixing hole 5 and the second fixing hole 3, thus preventing the belt mounting device from falling off during the limiting process of the limiting protrusion 12, which helps to improve the stability during use.

[0058] For example, please see Figures 2-4 The first fixing hole 5 can be a through hole, and the second fixing hole 3 is a threaded hole. The fasteners are screws or bolts. Maintenance personnel can fix the belt mounting device simply by using screws or bolts, which is convenient to operate and helps to improve work efficiency.

[0059] Screws or bolts are universal components, making them simpler and easier to understand to operate, which helps reduce tool training costs.

[0060] In some embodiments, the first fixing hole 5 is one, and the maintenance personnel only need to operate one fastener to fix the belt mounting device on the pulley 2 so as to install the belt. This method is simple to operate, reduces the workload of maintenance personnel in the maintenance process, and helps to improve maintenance efficiency and reduce maintenance personnel costs.

[0061] In some embodiments, the cross-sections of the body 1 and the fixing part 10 are arc-shaped. The end face with a larger diameter of the fixing part 10 is the outer annular surface, and the side face 103 with a smaller diameter facing the end face of the pulley 2 is the inner annular surface 102. When the pulley 2 has another pulley 2 with a smaller diameter coaxially arranged, the inner annular surface 102 can abut against the outer peripheral surface of the pulley 2 with a smaller diameter, or avoid interference with the outer peripheral surface of the pulley 2 with a smaller diameter.

[0062] The central angle of the annular fixing part 10 is between 15° and 40°, which helps to ensure that the curvature of the belt mounting device along the circumference of the pulley 2 is small, which helps to reduce the weight of the belt mounting device, making the belt mounting device easy to carry, operate and install, and reducing the cost of the belt mounting device.

[0063] Preferably, the central angle corresponding to the annular fixing part 10 is 20°. This angle reduces the size of the belt mounting device, which helps to reduce the weight of the belt mounting device and also helps to ensure the structural stability of the belt mounting device.

[0064] The fixing part 10 has at least one weight-reducing inclined surface 101, an inner ring surface 102 and a side surface 103. The inner ring surface 102 is the end face of the fixing part 10 facing the pulley 2. The two sides of the fixing part 10 along the circumference of the pulley 2 are the side surfaces 103. The weight-reducing inclined surface 101 is inclined from the inner ring surface 102 to the side surface 103.

[0065] The fixing part 10 is directly connected to the inner ring surface 102 and the side surface 103 at a right angle. By removing some material, the weight of the belt installation device is reduced, which makes the belt installation device easier to carry, operate and install, and helps to reduce the cost of the belt installation device.

[0066] like Figure 3 and Figure 4 The fixing part 10 is a single-arm structure, which forms a weight reduction space 11 between the side of the fixing part 10 away from the mounting surface 9 and the body 1. This removes some material corresponding to the weight reduction space 11, thereby reducing the weight of the belt installation device. This makes the belt installation device easier to carry, operate and install, and helps to reduce the cost of the belt installation device.

[0067] Specifically, the fixing part 10 of the single-arm structure is perpendicular to the body 1 and connected to the mounting surface 9 of the body 1, which serves as the second limiting surface 4 of the pulley 2 to abut against, thereby improving the stability of the fixed belt mounting device. It can also reduce the overall weight by reducing the thickness of the fixing part 10.

[0068] The limiting protrusion 12 protrudes towards the side of the body 1 away from the fixing part 10. Along the rotation direction of the pulley 2, the axial dimension of the limiting protrusion 12 gradually decreases, making the first limiting surface 6 an inclined surface.

[0069] When assembling the belt, rotating the pulley 2 can gradually push the belt onto the pulley 2 using the inclined surface of the first limiting surface 6, so as to achieve the meshing of the belt and the pulley 2.

[0070] After the belt assembly is completed, the maintenance personnel remove the fasteners. At this time, rotating pulley 2 will cause the belt mounting device to move away from pulley 2 under the reaction force of the belt, thus detaching the belt mounting device. This process achieves disassembly of the belt mounting device through mechanical movement, which reduces labor intensity, increases efficiency, and eliminates the need for manual operation by maintenance personnel, thereby reducing their workload.

[0071] The main body 1, the fixing part 10 and the limiting protrusion 12 are integrated into one structure, which helps to improve the structural stability of the connection between the main body 1, the fixing part 10 and the limiting protrusion 12.

[0072] The main body 1 has a weight reduction groove 8, which is located on the mounting surface 9 and is disposed near the fixing part 10.

[0073] The belt installation device reduces its weight through the weight reduction groove 8, which makes it easier to carry, operate and install, and reduces the cost of the belt installation device.

[0074] The belt installation device works together through the weight reduction space 11, the weight reduction groove 8, and the weight reduction inclined surface 101 to control the degree of the central angle corresponding to the fixing part 10 and the main body 1. This helps to control the overall weight of the belt installation device, which greatly reduces the cost of purchasing and storing maintenance tools. At the same time, it helps to greatly reduce the size of the belt installation device, making the device lighter, the working space smaller, and the supply chain operating costs lower.

[0075] Specifically, the belt mounting device weighs less than 0.1 kg, making it easy to carry, operate, and install. This significantly reduces the cost of the device and consequently, maintenance costs.

[0076] Now combined with the appendix Figures 1-4 The operation process of the belt installation device is explained.

[0077] First, such as Figures 1-4As shown, the belt mounting device is placed on the outer side 103 of the pulley 2, so that the mounting surface 9 is placed on the outer circumferential surface of the pulley 2. While maintaining the position without deflection, the maintenance personnel use bolts to pass through the first fixing hole 5 and the second fixing hole 3 to fix the belt mounting device on the pulley 2.

[0078] Then, the maintenance personnel placed the belt on the bearing surface 7, rotated the pulley 2, and under the limiting action of the first limiting surface 6, the belt gradually extended radially along the pulley 2, thus completing the belt assembly.

[0079] Finally, the maintenance personnel removed the bolts and continued to rotate the pulley 2, causing the belt mounting device to gradually move away from the belt under the reaction force of the belt acting on the first limiting surface 6 until it was completely disengaged from the belt.

[0080] The above process completes the installation of the belt.
