Abstract

The invention discloses an expansion sleeve synchronous pressing device and an expansion sleeve mounting method. According to the expansion sleeve synchronous pressing device, a part of self-contained bolts on an expansion sleeve are replaced by double-end studs, the double-end studs and the self-contained bolts are mutually spaced, and the rest self-contained bolts are tightened by a wrench; Tensioners are installed on the double-end studs, the tensioners abut against the inner ring of the expansion sleeve, a hydraulic pump is started to drive the tensioners to stretch the double-end studs, the tensioners flatten the expansion sleeve, and the wrench is adopted to tighten the bolts of the tensioners; and the tensioners and the double-end studs are dismantled, the taken-down self-contained bolts are installed, all the self-contained bolts are locked through the wrench, and assembling of the expansion sleeve is completed. According to the expansion sleeve synchronous pressing device and the expansion sleeve mounting method, the expansion sleeve is quick to mount, the working efficiency can be improved, the labor intensity of locking the expansion sleeve is greatly reduced, the bolt stress consistency is better, and the assembly quality can be improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a synchronous compression device for an expansion sleeve and an installation method for the expansion sleeve. Background technique [0002] In the process of connecting the main shaft and the gearbox, the expansion sleeve is a key component used to connect the main shaft and the gearbox. The expansion sleeve is divided into two parts, the inner ring and the outer ring. The outer ring is sleeved on the outer circle of the planetary carrier of the gearbox. Bolts are evenly distributed on the circumference of the inner ring. The outer circle of the inner ring of the expansion sleeve has a tapered surface. The outer ring of the expansion sleeve will squeeze the inner ring, and the inner ring will squeeze the planet carrier of the gearbox, and the planet carrier of the gearbox will clamp the main shaft, and finally achieve the purpose of torque transmission. [0003] At...
