Description

Technical Field

[0001] This utility model relates to the field of synchronous pulley technology, specifically a high-safety synchronous pulley structure with stable meshing. Background Technology

[0002] A synchronous pulley is a transmission device that transmits power through a synchronous belt. It is also called a synchronous belt pulley or belt pulley. It consists of a closed annular rubber belt with equally spaced teeth on its inner circumference and a corresponding pulley. Motion and power are transmitted by the meshing of the belt teeth with the grooves of the pulley teeth.

[0003] For example, Chinese patent CN203548798U (Aluminum Alloy Synchronous Pulley) includes an integrally structured mounting wheel and pulley. The inner diameters of the mounting wheel and pulley are equal, and their edges are provided with grooves 7mm deep. The outer diameter of the mounting wheel is 3-6cm smaller than that of the pulley. Three internally threaded mounting holes perpendicular to the axial direction of the synchronous pulley are evenly distributed on the outer circumference of the mounting wheel. 24-32 slots parallel to the axial direction are evenly distributed on the surface of the pulley. This utility model's aluminum alloy synchronous pulley has a relatively simple structure. The integrally structured mounting wheel and the grooves on it allow for smoother rotation of the synchronous pulley. The slots ensure a tighter and more secure connection between the synchronous pulley and the belt, making it convenient and practical. It can effectively improve energy-saving and emission-reduction efficiency and is suitable for large-scale promotion and use.

[0004] However, existing synchronous pulleys rely on single side limit baffles for positioning after meshing with the belt, lacking external limiting structures, resulting in poor limiting effect. They are prone to loosening and separation from the synchronous pulley, leading to shift in meshing position and poor stability and safety. Therefore, they do not meet current requirements. To address this, we propose a high-safety synchronous pulley structure for stable meshing. Utility Model Content

[0005] The purpose of this invention is to provide a stable and safe synchronous pulley structure to solve the problems mentioned in the background art, where existing synchronous pulleys rely on single side limit baffles for positioning after meshing with the belt, lack external limiting structures, have poor limiting effect, and are prone to loosening and separation from the synchronous pulley, resulting in shifting of the meshing position and poor stability and safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable meshing, high-safety synchronous pulley structure, including a pulley, the outer surface of which is provided with teeth, both ends of which are provided with external protrusions, a connecting seat is provided on one side of the external protrusion at one end of the pulley, a second limiting plate is provided outside the external protrusion with the connecting seat, a first limiting plate is provided outside the external protrusion at the other end of the pulley, an external protective component is provided between the first limiting plate and the second limiting plate, and the external protective component is located outside one side of the pulley, and there is a gap between the external protective component and the outer wall of the pulley.

[0007] Preferably, the first limiting plate and the second limiting plate are rotatably connected to the outer protrusion via ball bearings, the inside of the rotating wheel is provided with a connecting groove, and the connecting groove passes through the outer protrusion and the connecting seat, and the outer surface of the connecting seat is provided with a fixing groove.

[0008] Preferably, a stabilizing hole is provided on one side surface of both the first limiting plate and the second limiting plate, and the stabilizing hole penetrates through the first limiting plate and the second limiting plate.

[0009] Preferably, the external protective component includes an external protective plate, the inner wall of which is provided with an inner groove, and a rotating component is provided inside the inner groove, and a plurality of rotating components are provided.

[0010] Preferably, the rotating assembly includes a rotating column, the interior of which is provided with a shaft groove, and the interior of which is provided with a column shaft. After the column shaft passes through the shaft groove, its two ends are respectively heat-fused and fixed to the inner walls of the two sides of the inner groove.

[0011] Preferably, both ends of the outer protective plate are heat-fused with fixing plates, one side of the fixing plate is provided with fixing bolts, and both sides of the outer protective plate are fixed to the first limiting plate and the second limiting plate respectively by fixing bolts connected to the fixing plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides an external protective component between the first and second limiting plates. The first and second limiting plates are fixed to the motor's mounting plate via external fasteners through stabilizing holes. Furthermore, the first and second limiting plates rotate with the outer protrusion via ball bearings, ensuring that their positions remain unchanged when the wheel rotates. This prevents the external protective component from rotating. The wheel is connected to the belt via a toothed meshing connection. When the wheel rotates, the belt rotates together, and the external protective plate of the external protective component provides a limiting effect, preventing the belt from separating from the wheel along its outer direction. This improves meshing stability and solves the problem that existing synchronous pulleys, after meshing with the belt, rely on a single pair of side limiting baffles for limiting, lacking an external limiting structure, resulting in poor limiting effect and easy separation from the synchronous pulley due to loosening, leading to meshing position deviation and poor stability and safety.

[0014] 2. By setting an inner groove on the inner wall of the outer protective plate, and setting several rotating components inside the inner groove, the rotating components consist of a rotating column and a column shaft. When the wheel and the tire are meshing and rotating, the rotating column rotates under the force, avoiding friction between the tire and the inner wall of the outer protective plate, reducing friction, and improving service life and movement stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4This utility model provides an embodiment of a high-safety synchronous pulley structure with stable meshing, including a pulley 1. The outer surface of the pulley 1 is provided with teeth 9. Both ends of the pulley 1 are provided with external protrusions 10. A connecting seat 5 is provided on one side of the external protrusion 10 at one end of the pulley 1. A second limiting plate 3 is provided outside the external protrusion 10 with the connecting seat 5. A first limiting plate 2 is provided outside the external protrusion 10 at the other end of the pulley 1. An external protective component 4 is provided between the first limiting plate 2 and the second limiting plate 3, and the external protective component 4 is located at... The outer side of one side of the rotating wheel 1, and the outer protective component 4 has a gap with the outer wall of the rotating wheel 1. The first limiting plate 2 and the second limiting plate 3 are rotatably connected to the outer protrusion 10 through the ball bearing 11. The rotating wheel 1 is provided with a connecting groove 6, and the connecting groove 6 passes through the outer protrusion 10 and the connecting seat 5. The outer surface of the connecting seat 5 is provided with a fixing groove 7. The first limiting plate 2 and the second limiting plate 3 are both provided with a stabilizing hole 8 on one side surface, and the stabilizing hole 8 passes through the first limiting plate 2 and the second limiting plate 3. The outer protective component 4 includes an outer protective plate 12.

[0022] The first limiting plate 2 and the second limiting plate 3 are fixed to the motor fixing plate (not shown in the figure) by external fasteners through the stabilizing hole 8. When the wheel 1 rotates, the first limiting plate 2 and the second limiting plate 3 rotate with the outer protrusion 10 through the ball bearing 11, keeping their positions unchanged, thereby driving the external protective component 4 to not rotate. The wheel 1 is connected to the tire (not shown in the figure) through the toothed 9. When the wheel 1 rotates, the tire rotates together. It is limited by the external protective plate 12 of the external protective component 4 to prevent the tire from separating and falling off the wheel 1 along the external direction of the wheel 1, thereby improving the stability of the meshing.

[0023] Please see Figure 3 , 4 The outer protective plate 12 has an inner groove 13 on its inner wall. A rotating assembly 14 is provided inside the inner groove 13. Several rotating assemblies 14 are provided. Each rotating assembly 14 includes a rotating column 17. A shaft groove 19 is provided through the rotating column 17. A column shaft 18 is provided inside the shaft groove 19. After the column shaft 18 passes through the shaft groove 19, its two ends are respectively heat-fused to the inner walls of the inner groove 13. The outer protective plate 12 of the outer protective assembly 4 provides a limit to prevent the tire from falling off when it is connected to the wheel 1, thereby improving the stability of the meshing. Furthermore, the rotating column 17 rotates under force, preventing the tire from rubbing against the inner wall of the outer protective plate 12, reducing friction, and improving service life and movement stability.

[0024] Please see Figure 1 , 23. Both ends of the outer protective plate 12 are heat-fused with fixing plates 15. One side of the fixing plate 15 is provided with fixing bolts 16. The two sides of the outer protective plate 12 are fixed to the first limiting plate 2 and the second limiting plate 3 respectively through the fixing bolts 16 on the fixing plate 15. This facilitates the installation and disassembly of the outer protective plate 12, and also facilitates the installation and disassembly of the outer protective component 4, thereby facilitating replacement and improving convenience.

[0025] Working principle: In use, the side of the outer protective plate 12 with the inner groove 13 faces the rotating wheel 1. The two sides of the outer protective plate 12 are fixed to the first limiting plate 2 and the second limiting plate 3 respectively by fixing plates 15 and external fixing bolts 16. The rotating wheel 1 is connected to the motor shaft (not shown in the figure) through the connecting groove 6 and fixed by the fasteners connected to the fixing groove 7. The rotating wheel 1 is driven to rotate by the motor shaft of the motor. This is the prior art.

[0026] The first limiting plate 2 and the second limiting plate 3 are fixed to the motor mounting plate (not shown in the figure) by external fasteners connected to the stabilizing hole 8. When the wheel 1 rotates, the first limiting plate 2 and the second limiting plate 3 rotate with the outer protrusion 10 through the ball bearing 11, keeping their positions unchanged, thereby preventing the external protective component 4 from rotating. The wheel 1 is connected to the tire (not shown in the figure) by meshing with the toothed belt 9. When the wheel 1 rotates, the tire rotates together. It is limited by the external protective plate 12 of the external protective component 4 to prevent the tire from separating from the wheel 1 along the external direction of the wheel 1, thereby improving the stability of meshing. Furthermore, it rotates by the force of the rotating column 17 to prevent the tire from rubbing against the inner wall of the external protective plate 12, reducing friction and improving service life and movement stability.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
