A kind of stud nut pre-embedded sleeve and pre-embedded method

Abstract

The invention discloses an embedding sleeve of a stud and a nut. The embedding sleeve comprises a shell, an inner sleeve and a nut loop, wherein the outer shell is provided with an inner cavity, a boss is arranged on one end of the inner cavity, the inner sleeve is in threaded connection with the inner cavity, and pushes against the boss, the inner sleeve is internally provided with internal threads matched with external threads of the stud, a connector butted with a driving end is arranged on one end, close to the boss, of the outer shell, the nut loop sleeves one end, far away from the boss, of the inner cavity, and a limiting assembly for limiting one-way rotation of the nut loop is arranged between the outer shell and the nut loop. The invention further correspondingly discloses an embedding method of the stud and the nut, in which the embedding sleeve is adopted for synchronously assembling the nut and the stud. The embedding sleeve and the embedding method have the advantages that operation is simple and convenient, the nut and the stud can be rapidly and synchronously assembled, and the like.

Description

technical field [0001] The invention mainly relates to the technical field of wind power generation, in particular to a stud nut embedded sleeve and an embedded method. Background technique [0002] Wind turbines and other large mechanical facilities are assembled from multiple mechanical parts, and the connections between the components are often connected in a detachable way, most of which are connected by studs. For example, in large megawatt wind turbines, the components The large fasteners connected are generally connected by studs and nuts. The installation of pitch bearings, yaw bearings, main bearing housings, and yaw setters of our 2MW and 2.5MW wind turbine generator sets adopts the connection method of studs with nuts, and the number of studs for a single fan reaches 450. [0003] In the fan assembly process, each stud needs to be pre-embedded in the thread of the fixed body. The length of the thread of the stud and the thread of the fixed body is generally about...

AI Technical Summary

Problems solved by technology

After the stud is screwed in, the nut is screwed into the stud until the washer fits. There is often a certain distance between the stud head and the end surface of the nut. The number of studs is large, and it takes a long time to complete the above operations

For example: it takes 1.5h / 2 people to pre-install the pitch bearing studs of a 2WM wind turbine in our company. The whole process takes a long time and repetitive actions make it difficult for the operator to continue to complete the work
