Problems solved by technology

[0002] AGV has been widely used in logistics and robotic flexible manufacturing systems. Most of the motors and reducers are connected to the wheel body in series through the coupling. The axial dimension of the wheel train is too large, thus reducing the transmission accuracy and increasing the structural size, and also increasing the manufacturing cost

Abstract

The invention relates to the technical field of mechanical manufacturing, and provides a high-precision compact AGV driving wheel assembly. According to the structure of an existing AGV driving wheel, mostly, a motor and a speed reducer are coupled to the wheel body of the AGV driving wheel in the multistage link manner through connecting pieces so as to form an intermediate link that generates an accumulated error. Meanwhile, a structure with a large axial size is also formed, so that the transmission precision is reduced. The manufacturing cost is improved. According to the technical scheme of the invention, an RV reducer is applied to the robot technology and is compact in structure and high in precision. The RV reducer is arranged inside the wheel body of the driving wheel, and a high-precision servo motor with a code disc is directly connected with the speed reducer. In this way, the zero redundancy of the axial size is achieved and a transmission chain and the axial size thereof are reduced. Therefore, the accumulation of transmission errors is avoided, and the integrity is improved. The number of parts is reduced. Meanwhile, the frictional resistance between the pedal surface of the driving wheel and the ground is increased. The number of factors that cause the traveling error of the AGV is reduced, so that the AGV driving wheel assembly is high in precision and compact.
