The utility model discloses a fastening structure of a transmission wheel, which comprises a transmission shaft and a transmission wheel sleeved on the transmission shaft. The utility model is characterized in that an inner cone sleeve is arranged on the transmission shaft, an outer cone sleeve is arranged on the outer part of the inner cone sleeve, the inner cone sleeve and the outer cone sleeve are arranged in the installation hole of the transmission shaft, and the outer wall of the outer cone sleeve and the installation hole are arranged on the transmission shaft. When the side wall contacts, the transmission wheel is fastened on the transmission shaft through the mutual extrusion between the inner cone sleeve and the outer cone sleeve, and the mounting hole of the transmission wheel is a step hole. A thrust inner cone sleeve or an outer cone sleeve is installed on the end face of the non-step end of the mounting hole, so that the two cone sleeves have a radial expansion tendency, and the compression parts are set on the transmission shaft through screws. The wheel is on the moving wheel. The fastening structure of the driving wheel of the utility model adopts the conical expansion sleeve structure to replace the pin connection and fastening screw fastening connection, thereby reducing the workload of assembly, simple operation and reliable installation, convenient disassembly, simple maintenance, and greatly reducing the maintenance time and cost.
