The utility model discloses a walking built-in transmission mechanism, which comprises a clamp-shaped crawler rack with one end open and another end closed. The opening end of the crawler rack is a head, the head of the crawler rack is a parallel side plate of the crawler rack, the side plates of the crawler rack on both sides are symmetrically provided with through holes, and the driving wheels are installed through the central holes between the side plates of the crawler rack. The planetary gear reducer is connected and driven, and the motor is connected with the planetary gear reducer through the external spline shaft of the coupling. The other side of the planetary gear reducer is supported by a half-shaft connection. The half-shaft is supported by a bearing installed on the through hole of the side plate of the crawler rack on one side. The flange at the end of the shell of the planetary gear reducer is fixed with the side plate of the crawler rack on the other side. Fixed connection. The walking mechanism cancels the drive shaft and adopts the structure of the built-in planetary gear reducer. It has compact overall structure, small size, light weight, low production cost, stable transmission, long service life, and reduces the maintenance cost and use cost of users.
