The invention relates to an edge pressure mitigation groove shaft. A main rotor shaft of a wind turbine configured to reduce contact pressure at a hub-joint junction includes a flange portion and a rod portion. The flange portion includes an outer circumferential edge, an outer radial region, and an inner radial region. The outer radial region includes an aperture disposed about the outer radial region for attachment to a wind turbine hub. The outer circumferential edge includes a groove disposed atop the outer circumferential edge. The rod portion is formed with the inner radial region and is configured for connection to a gearbox of a wind turbine. 本发明涉及边缘压力减轻凹槽轴。一种构造成减小毂-接头连接处的接触压力的风力涡轮的主转子轴包括凸缘部分和杆部分。凸缘部分包括外周向边缘、外径向区域以及内径向区域。外径向区域包括围绕外径向区域安置的孔，以用于附接到风力涡轮毂。外周向边缘包括安置在外周向边缘的顶上的凹槽。杆部分与内径向区域一起形成，并且构造成用于连接到风力涡轮的齿轮箱。
