Abstract
The invention relates to an impeller, which comprises a hub, vanes and positioning keys. The vanes are arrayed on the hub around the axis of the hub circularly, and the positioning keys arranged between the hub and the vanes are used for fixing the vanes onto the hub. The root of each vane is cylindrical, a first positioning groove is arranged on the side wall of the root of the vane, a second positioning groove is arranged in the first positioning groove, and the width of the second positioning groove is smaller than that of the first positioning groove. Each positioning key comprises a first clamp block and a second clamp block, wherein the first clamp block is matched with the first positioning groove, and the second clamp block is fixedly connected with one side of the first clamp block and matched with the second positioning groove. Since the first clamp blocks and the second clamp blocks of the positioning keys are respectively embedded in the first positioning grooves and the second positioning grooves of the roots of the vanes, the connection strength between the vanes and the hub is enhanced greatly by double-layer interference-fit connection.
