Abstract
The invention discloses a transmission mechanism, a steering control device and an agricultural machine, and the transmission mechanism comprises a transmission main shaft which comprises a main shaft main body made of a plastic material, and the main shaft main body is sleeved with a first bearing and a second bearing; the main machine shell is provided with a supporting shaft sleeve, the first bearing and the second bearing are both installed in the supporting shaft sleeve, the central axes of the first bearing and the second bearing coincide, and the transmission main shaft is rotationally installed in the main machine shell. Compared with a traditional metal structure, the plastic main shaft body has the advantages of being light in weight, easy to machine, low in cost and the like. Importantly, according to the scheme, the first bearing and the second bearing which are used for supporting the transmission main shaft are installed in the same supporting shaft sleeve, that is, the transmission main shaft is independently supported through one structural part, and the installation coaxiality of the first bearing and the second bearing is guaranteed; the problem that the main shaft body which is soft in texture is distorted and bent by the first bearing and the second bearing which are low in coaxiality is solved, and it is guaranteed that the transmission main shaft made of plastic materials can stably operate.
