While maintaining the original weight, the engagement area of the ratchet—assuming an identical tooth count—has been increased by approximately 20%. This significantly enhances the load-bearing capacity of the planetary gear system, rendering power transmission more stable and reliable. Furthermore, this enlarged engagement area provides a higher degree of redundancy in the ratchet's engagement state, thereby substantially bolstering operational stability. This specific guide design enables the pawls to engage with the gear more smoothly and precisely, resulting in a faster engagement process, significantly reduced backlash, and a more direct power response.
