AI Technical Summary

Technical Problem

In wind power generation equipment, the installation of the shaft system and bearing housing structure presents problems with shaft concentricity and bearing clearance. Conventional adjustment methods are difficult to guarantee high precision, and the radial force caused by gravity when the shaft system is horizontally set affects the installation accuracy.

Method used

A platform shaft system electric turning machine tooling is adopted, including a base, a slewing support, a drive motor, a transmission gear set, a slewing worktable, and a multi-turn mounting hole set. The drive motor drives the slewing worktable to rotate, and precise adjustment is achieved by combining Hall sensors and torque sensors to adapt to the fixed positioning of bearing seat structures of different specifications.

Benefits of technology

It achieves high-precision adjustment of the shaft system within the bearing housing structure, is easy to operate, has strong applicability, can meet the fixed positioning requirements of bearing housings of different specifications, and improves installation accuracy and adjustment efficiency.

Abstract

A rotary support is rotatably supported on a base, a driving motor in the base is meshed with a rotary inner gear ring of an inner ring of the rotary support through a transmission gear set, a rotary worktable is positioned, locked and supported on the rotary support, and a plurality of circles of mounting hole sets are arranged on the rotary worktable around the same rotary center. Each mounting hole group comprises a plurality of mounting holes which are formed around the circumference and are used for locking and connecting a shaft system end flange ring, the base is externally connected with an abutting fixed seat, an adjusting track seat is locked and supported on the abutting fixed seat, an abutting frame is adjustably positioned and supported on the adjusting track seat, and a rotation stopping locking bolt is connected to the abutting frame in a penetrating manner. According to the tool, a rotating table is adopted to drive a shafting to rotate, meanwhile, a bearing seat structure outside the shafting is positioned through a connecting frame, monitoring of torque, rotating speed and the number of turns is combined, and the mounting precision of the shafting is adjusted through turning operation.
