Description

Technical Field

[0001] The utility model relates to the technical field of synchronous belts, in particular to a herringbone synchronous belt with reduced noise. Background Art

[0002] The herringbone synchronous belts commonly seen on the market are prone to generate loud noise during high-speed operation due to the friction and vibration between the belt body and the pulley, which has an adverse effect on the working environment and operators. Although there are some synchronous belt design solutions for reducing noise, these solutions often have the disadvantages of complex structure, high manufacturing cost or insignificant noise reduction effect. Therefore, we propose a herringbone synchronous belt with simple structure and low manufacturing cost to reduce noise. Utility Model Content

[0003] In order to overcome the shortcomings of the existing noise reduction synchronous belts, such as complex structure, high manufacturing cost or insignificant noise reduction effect, the utility model provides a noise reduction herringbone synchronous belt with simple structure and low manufacturing cost.

[0004] A noise-reducing herringbone synchronous belt comprises a thin plate layer, the top of the thin plate layer is fixedly connected with equidistantly distributed oblique teeth, the oblique teeth are provided with a center hole, the bottom of the thin plate layer is fixedly connected with a reinforcement layer, the bottom of the reinforcement layer is fixedly connected with a covering layer, the inside of the thin plate layer is fixedly connected with equidistantly distributed connecting strips, and the inside of the reinforcement layer is fixedly connected with a grid frame.

[0005] Furthermore, the helical teeth are made of a low-friction, high-wear-resistant material, such as rubber or polyurethane.

[0006] Furthermore, the tooth shape of the helical teeth is an arc structure, which is used to reduce the impact force during meshing.

[0007] Furthermore, the connection surface between the thin plate layer and the reinforcement layer is a wavy surface composed of multiple inclined surfaces at different angles, which is used to increase the contact area and thus increase the stability of the connection.

[0008] Furthermore, the connection surface between the reinforcement layer and the coating layer is a concave-convex interlaced structure, which is used to increase the contact area to increase the stability of the connection.

[0009] Furthermore, the coating layer is made of a high elasticity and high damping material, such as rubber or silicone.

[0010] The utility model has the following advantages: 1. The hollow structure, the helical teeth of the flexible material meshing with the pulley can reduce vibration and thus reduce noise. At the same time, under the action of the high elasticity and high damping material of the coating layer, it can effectively absorb and disperse the vibration energy generated by the belt body during operation, further reducing noise.

[0011] 2. When the synchronous belt is running, the grid frame of the reinforcement layer and the connecting strips of the thin plate layer can enhance the structural stability, and at the same time improve the stress distribution, prevent the synchronous belt from premature fatigue or local damage, and extend the service life of the synchronous belt.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1: A herringbone timing belt with reduced noise, such as Figure 1-Figure 4 As shown, it includes a thin plate layer 1, oblique teeth 2, a reinforcement layer 3, a covering layer 4, a connecting strip 5 and a grid frame 6. The left and right parts of the upper side of the thin plate layer 1 are fixedly connected with equally spaced oblique teeth 2. The oblique teeth 2 are made of low-friction, high-wear-resistant materials such as rubber or polyurethane. The tooth shape of the oblique teeth 2 is an arc structure, which is used to reduce the impact force during meshing. A center hole 7 is opened in the oblique teeth 2. The lower side of the thin plate layer 1 is fixedly connected with the reinforcement layer 3. The connecting surface of the thin plate layer 1 and the reinforcement layer 3 is a wavy surface composed of multiple oblique surfaces at different angles. Used to increase the contact area to increase the stability of the connection. The coating layer 4 is fixedly connected to the lower side of the reinforcement layer 3. The connecting surface between the reinforcement layer 3 and the coating layer 4 is a concave-convex interlaced structure, which is used to increase the contact area to increase the stability of the connection. The coating layer 4 is made of high-elasticity and high-damping materials, such as rubber or silicone, which can effectively absorb and disperse the vibration energy generated by the belt during operation, thereby reducing the generation of noise. Equidistantly distributed connecting strips 5 are fixedly connected in the thin plate layer 1, and a grid frame 6 is fixedly connected in the reinforcement layer 3.

[0019] When the device is used, the pulley meshes with the bevel teeth 2 on the thin plate layer 1 to drive the thin plate layer 1 to move. When the bevel teeth 2 mesh with the pulley, since the tooth shape of the bevel teeth 2 is an arc structure, the impact force when the pulley and the bevel teeth 2 mesh can be reduced, thereby reducing vibration and noise. Moreover, since the bevel teeth 2 are a hollow structure and the material has low friction and high wear resistance, the friction of the bevel teeth 2 being squeezed by the pulley can also be reduced, reducing the generation of vibration and further reducing noise. At the same time, under the action of the high elasticity and high damping material of the coating layer 4, the vibration energy generated by the belt body during operation can be effectively absorbed and dispersed, further reducing the generation of noise. When the synchronous belt is running, under the action of the grid frame 6 of the reinforcement layer 3 and the connecting strip 5 embedded in the thin plate layer 1, the structural stability can be enhanced to ensure that the synchronous belt has sufficient rigidity and stability to avoid deformation or breakage when running at high speed or bearing a large load. At the same time, the stress distribution can also be improved to prevent the synchronous belt from premature fatigue or local damage, thereby extending the service life of the synchronous belt.
