AI Technical Summary
In traditional tracked walking mechanisms, fretting wear and concentrated impact loads are prone to occur between the drive shaft and the flange, leading to loose connections and deterioration of fit accuracy, affecting power transmission efficiency, and in severe cases, causing transmission failure.
By setting a limiting part and a limiting groove on the drive shaft, combined with the fixed connection of the limiting baffle and the flange, the connection method between the flange and the drive shaft is optimized, and its stability is enhanced.
It improves the connection stability between the flange and the drive shaft, reduces the impact of long-term high load or frequent start-stop operation on the connection, and improves power transmission efficiency and running smoothness.

Abstract
Claims
1. A track walkway characterized by, include: Track assembly, including the drive sprocket; A drive assembly includes a drive shaft, a flange, and a limiting baffle. The drive shaft has a shaft body and a plurality of limiting parts. The plurality of limiting parts are circumferentially spaced on the shaft body, and each limiting part protrudes radially from the shaft body. The shaft body is provided with a mounting groove that extends circumferentially and is located axially close to the plurality of limiting parts. The flange and the drive wheel are both sleeved on the shaft body, and the drive wheel is fixedly connected to the flange. The flange has multiple limiting grooves on its inner wall. The multiple limiting grooves are spaced apart along the circumference of the inner wall. Each limiting part passes through a limiting groove and abuts against the groove wall. The limiting baffle is embedded in the mounting groove and is connected to the flange.
2. The track according to claim 1, characterized in that The tracked traveling mechanism further includes an end assembly, which is disposed at one end of the shaft portion close to the drive wheel along the axial direction of the shaft portion and abuts against the end of the drive wheel away from the flange along the axial direction of the shaft portion.
3. The track according to claim 2, characterized in that The end assembly includes a limiting sleeve, which is sleeved on the shaft portion, and one end of the limiting sleeve along the axial direction of the shaft portion abuts against the drive wheel.
