Abstract
The utility model discloses a tool for disassembling a cylindrical roller bearing outer ring of a wind driven generator, which comprises a fixing ring, a nut and screw rods, wherein a plurality of hole sites are uniformly distributed on the fixing ring along the circumferential direction of the fixing ring, the number of the screw rods is consistent with that of the hole sites, one screw rod penetrates through one hole site, a hook is processed at one end of each screw rod, the fixing ring is arranged on the end surface of a hollow shaft, the axis of the fixing ring is aligned with that of the hollow shaft, the hook extends into a gap between the bearing outer ring and a bearing roller and hooks the bearing outer ring, the nut is screwed into the other end of each screw rod, the nut is abutted against the fixing ring, and the nut is sequentially screwed so as to pull out the bearing outer ring. The utility model solves the problem that the outer ring of the large cylindrical roller bearing on the generator which is horizontally arranged on the tower of the wind driven generator is difficult to disassemble.
Description
Technical Field
The utility model relates to the technical field of wind driven generators, in particular to a tool for disassembling an outer ring of a cylindrical roller bearing of a wind driven generator.
Background
Along with the continuous increase of the single machine capacity of the wind generating set, the bearing used by the generator is larger and larger, the semi-direct-drive wind driven generator is horizontally installed on the site, the cylindrical roller bearing is positioned between the hollow shaft and the bearing sleeve and cannot be directly detached by hand, and therefore a certain tool is needed to be used.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, provides a tool for disassembling an outer ring of a cylindrical roller bearing of a wind driven generator, and solves the problem that the outer ring of a large cylindrical roller bearing on a generator which is horizontally arranged on a tower of the wind driven generator is difficult to disassemble.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the utility model provides a frock is dismantled to aerogenerator cylinder roller bearing outer lane, includes solid fixed ring, nut and screw rod, gu fixed ring goes up along its circumference equipartition has a plurality of hole sites, the quantity of screw rod is unanimous with the quantity of hole site, a screw rod passes a hole site, and the one end of every screw rod all processes the hook, will gu fixed ring adorns on the terminal surface of hollow shaft, and its axis aligns with the axis of hollow shaft, the hook stretches into the clearance department of bearing outer lane and bearing roller to catch on the bearing outer lane, the nut is all twisted to the other end of every screw rod, the nut is contradicted solid fixed ring, thereby screws up the nut in proper order and extracts the bearing outer lane.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the tool has the advantages of simple structure, convenience in operation, high dismounting efficiency and the like, can be used for dismounting the outer ring of the large cylindrical roller bearing on the generator which is horizontally arranged on the wind driven generator tower, avoids the situation that the bearing is damaged and cannot be replaced, and greatly improves the dismounting efficiency compared with the existing dismounting tool.
