However, in the above solution, the gears are connected together through pins or links. When force is applied to the gears or gear shafts, the tension of the pins will increase, causing the shaft connection point to bear greater stress. Therefore, the utility model proposes a high-torque new energy gear shaft. Utility Model Content

[0005] The utility model mainly provides a high-torque new energy gear shaft which can distribute stress more evenly and thus reduce point stress.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a high-torque new energy gear shaft, comprising a shaft body and a gear body, the outer side of the gear body is fixedly connected with a connecting component, and the inner wall of the connecting component is provided with a reinforcing component;

The hardness layer provides wear resistance and anti-friction protection, while the strength layer ensures the stability of the connection under high load conditions, thereby reducing the risk of breakage or loosening during system operation.

[0010] Preferably, the outer side of the concave surface is slidably connected to the connecting groove.

[0011] The technical effect of adopting the above further solution is: ensuring the tightness and stability of the connection, making it difficult for the connection point to loosen or deviate, thereby ensuring the stable transmission of the gear shaft system.

[0012] Preferably, the bottom end of the connecting block is engaged with the slot.

[0013] The technical effect of adopting the above further solution is that the connecting block can be firmly fixed on the chassis to prevent it from loosening or falling off during operation, thereby ensuring the stable transmission of the gear shaft system.

[0014] Preferably, the outer side of the convex surface is slidably connected to the connecting groove.

[0015] The technical effect of adopting the above further solution is that a tighter and more stable mechanical connection can be achieved. Due to the matching of the convex shape and the connection groove, the pressure can be better dispersed when subjected to external force.

[0016] Preferably, the bottom end of the connecting block is engaged with the chassis.

[0017] The technical effect of adopting the above further solution is that the snap-fit ​​design can make the assembly process simpler and faster, and the connecting block can be directly snapped into the preset position of the chassis during installation.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, by setting a connection component, the outer sides of the concave and convex surfaces in the connection component are slidably connected to the connection groove, thereby achieving a stable connection. This design allows the connection block to be tightly fixed on the shaft body, ensuring the stability and reliability of the connection. When the gear shaft system is running, the sliding connection of the concave and convex surfaces on the connection groove can effectively transmit torque, achieve the stability and reliability of the connection, reduce friction loss, ensure the effective transmission of torque, effectively prevent the loosening of the connection parts during operation, and reduce the failure and damage caused by loosening. At the same time, through the sliding connection of the concave and convex surfaces on the connection groove, the friction loss is reduced and the energy utilization rate is improved.

[0020] 2. In the utility model, by setting a reinforcement component, the reinforcement component uses titanium alloy material as the strength layer of the connecting component, and the design of adding a hardness layer and a strength layer inside the connecting component, the stability, durability and performance of the gear shaft system under high load and harsh environment are improved.
