Wind power ring blank capable of reducing stress concentration and preparation process thereof

Abstract

The invention discloses a wind power ring blank capable of reducing stress concentration and a preparation process thereof. An inner sleeve is connected with the inner wall of a ring body in an interference fit mode, so that the assembled wind power ring blank is connected more tightly, positioning holes are matched with first threaded holes, locking bolts installed at the positioning holes guarantee the connection tightness of the wind power ring blank and can effectively reduce stress concentration, when the wind power ring blank is prepared, the ring body and an inner sleeve blank are prepared firstly, then rough turning is conducted on the ring body and the inner sleeve blank, hardening and tempering are conducted, then finish machining is carried out, stress relief annealing is performed on the inner sleeve blank, stress relief annealing can relieve stress and ensure the hardness of the inner sleeve, then, natural cooling and assembly of the inner sleeve are carried out, the windpower ring blank is connected more tightly through interference fit, and the whole wind power ring blank has obviously reduced stress concentration phenomenon and high strength as compared with traditional parts after installation; and meanwhile, the preparation process of the wind power ring blank is relatively simple.

Description

technical field [0001] The invention relates to a wind power component, in particular to a wind power ring blank with reduced stress concentration and a preparation process thereof. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Although there are many kinds of wind turbines, they can be summarized into two categories: ①Horizontal axis wind turbines, the rotation axis of the wind rotor is parallel to the wind direction; ②Vertical axis wind turbines, the rotation axis of the wind rotor is perpendicular to the ground or air flow direction. [0003] Both horizontal axis wind turbines and vertical axis wind turbines used in wind power generation require special wind power rings. Win...

Problems solved by technology

Wind power rings play an important role in wind power systems, and their stability is particularly important. Wind power rings are subject to enormous torque during equipment operation, and the strength of existing wind power rings is difficult to meet the requirements. At the same time, wind power rings are There is a large stress concentration phenomenon during preparation, which affects the stability of wind power equipment
