Features: The surface coating has been changed to a thicker chromium nitride coating to improve adhesion to the substrate and enhance wear resistance. This guiding design allows the pawl to engage more smoothly and precisely in the tooth groove, accelerating the engagement process, significantly reducing lost motion, and achieving a more direct power response. The new ratchet structure automatically returns to a concentric position, ensuring stable movement along the same axis during transmission, effectively reducing ratchet deflection and improving engagement stability. When a torque of 230 N·m was simulated on the tooth surface, peak stress was reduced by approximately 32%. Under the same equivalent conditions, the service life of 36T bevel gears is significantly longer than that of 36T flat gears. While maintaining the same weight, the meshing area is increased by approximately 38%, significantly improving the planetary gear's load-bearing capacity and ensuring more stable and reliable power transmission. Furthermore, the larger meshing area ensures simultaneous operation of multiple teeth, allowing continued operation even if a single tooth fails. Compared to the previous generation 36-tooth flat gear, the 36-tooth helical gear offers greater redundancy, further improving operational stability and significantly reducing the risk of tooth breakage.
