Abstract
Description
Technical Field
[0001] This utility model relates to the field of synchronous belt technology, specifically a high-strength synchronous belt with shock absorption function. Background Technology
[0002] Synchronous belts consist of a steel wire rope or fiberglass rope as the reinforcing layer, covered with polyurethane or neoprene rubber. The inner circumference of the belt is toothed to mesh with toothed pulleys. Because the reinforcing layer deforms little under load, it maintains a constant pitch, preventing relative slippage between the belt and pulleys and ensuring synchronous transmission with a constant transmission ratio. In the field of mechanical transmission, synchronous belts are widely used in new energy vehicle motors, industrial automation equipment, and precision instruments as a core component for achieving precise transmission. However, current high-strength synchronous belts lack vibration damping capabilities and have limited elastic deformation capacity. Under high-speed transmission or sudden load changes, synchronous belts cannot effectively absorb vibration energy, resulting in large vibration amplitudes and easy breakage. Therefore, we propose a high-strength synchronous belt with vibration damping function. Utility Model Content
[0003] The purpose of this invention is to provide a high-strength synchronous belt with shock absorption function. It has the advantage of shock absorption function and solves the problem that current high-strength synchronous belts do not have shock absorption function, have limited elastic deformation capacity, and cannot effectively absorb vibration energy during high-speed transmission or sudden load changes, resulting in large vibration amplitude and easy breakage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength synchronous belt with shock absorption function, comprising a synchronous belt body, wherein the synchronous belt body comprises a wear-resistant rubber layer, a high-temperature resistant protective layer, an antistatic layer, a shock-absorbing layer, a tensile reinforcement layer, and a thermally conductive layer, wherein the shock-absorbing layer comprises a sponge-like EVA elastomer layer and a honeycomb polyurethane elastomer layer, wherein the sponge-like EVA elastomer layer is located outside the honeycomb polyurethane elastomer layer.
[0005] Preferably, the wear-resistant rubber layer is a silicone rubber-based composite material, the high-temperature resistant protective layer is ceramic fiber reinforced silicone rubber, and the antistatic layer is conductive carbon black filled rubber.
[0006] Preferably, the tensile reinforcing layer is a blended mesh of glass fiber and aramid fiber, and the thermally conductive layer is graphene-modified rubber.
[0007] Preferably, the wear-resistant rubber layer is located outside the high-temperature resistant protective layer, and the high-temperature resistant protective layer is located outside the antistatic layer.
[0008] Preferably, the antistatic layer is located outside the damping layer, the damping layer is located outside the tensile reinforcement layer, and the tensile reinforcement layer is located outside the thermally conductive layer.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This utility model uses a shock-absorbing layer composed of a sponge-like EVA elastomer layer and a honeycomb-like polyurethane elastomer layer. The sponge-like EVA elastomer layer preferentially absorbs low-frequency vibrations, while the honeycomb-like polyurethane elastomer layer attenuates high-frequency vibrations through air damping effect, effectively suppressing synchronous belt body resonance, significantly improving transmission stability, and reducing equipment failure rate.
[0011] 2. This utility model utilizes a silicone rubber-based composite material for the wear-resistant rubber layer, which enables the synchronous belt body to have excellent wear resistance. The tensile reinforcement layer employs a hybrid mesh structure of glass fiber and aramid fiber, balancing high strength and tear resistance to effectively withstand transmission loads, reduce belt elongation and deformation, and extend service life. The high-temperature protective layer uses a ceramic fiber-reinforced silicone rubber structure to resist thermo-oxidative aging under high-temperature environments and maintain the stability of the belt's mechanical properties. The antistatic layer uses conductive carbon black-filled rubber to quickly discharge transmission static electricity, avoiding dust adsorption and static electricity hazards. The thermally conductive layer uses graphene-modified rubber to accelerate heat dissipation, reduce belt temperature, and delay material degradation. Attached Figure Description

The wear-resistant rubber layer 2 uses a silicone rubber-based composite material, which enables the synchronous belt body 1 to have good wear resistance. The tensile reinforcement layer 6 uses a glass fiber and aramid fiber mixed mesh structure, which takes into account both high strength and tear resistance, effectively bearing transmission loads, reducing belt elongation deformation, and extending service life. The high-temperature resistant protective layer 3 uses a ceramic fiber reinforced silicone rubber structure to resist thermo-oxidative aging under high-temperature environment and maintain the stability of the belt's mechanical properties.
