The invention discloses a milling wheel and belongs to the technical field of engineering machines. The milling wheel comprises a wheel hub and a plurality of milling tooth assemblies. The milling tooth assemblies are distributed on the outer circumferential surface of the wheel hub in a spiral line shape. Each milling tooth assembly comprises a tooth base plate and a milling tooth arranged on thetooth base plate. Projections of the adjacent milling teeth on the wheel hub in the outer circumference expanding direction overlap with one another. The milling wheel provided by the invention is high in slag carrying capability, a rock wall can be prevented from being formed, abrasion is less, and the service life is long.
