Description
Technical Field
The utility model belongs to the technical field of the bearing assembly, a assembly fixture is related to, especially, relate to a MW level permanent magnetism direct drive generator bearing assembly fixture.
Background
The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. At present, the permanent magnet direct drive generator of megawatt level has the disadvantages that the bearings are large bearings, the assembly steps are more complicated, and the efficiency is lower. Most of the existing bearing assembly methods are a step-by-step assembly method, wherein an outer ring (or an inner ring) of a bearing is assembled in advance, and then the inner ring (or the outer ring) is assembled.
In order to improve the efficiency of the bearing assembly of the MW-level permanent magnet direct-drive generator, people need a tool capable of realizing the integral assembly of the bearing, so that the requirements of production and life are met.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of existence among the prior art, provide a MW level permanent magnetism direct drive generator bearing assembly fixture, have the advantage that assembly efficiency is high.
The purpose of the utility model is realized like this: the utility model provides a MW level permanent magnetism direct drive generator bearing assembly fixture, including the jib, the connecting rod, special-shaped crank, the chuck, the jib upper surface is provided with rings, the rings lower extreme is provided with the connecting rod mount pad, be provided with the connecting seat on the outer face of cylinder of jib, the one end and the connecting rod mount pad of connecting rod are connected, the other end and the articulate one end of special-shaped of connecting rod are connected, special-shaped crank middle part is connected with the connecting seat, special-shaped articulate other end and chuck are connected, circumference equidistance is provided with three screw hole on the face of cylinder of connecting seat.
Preferably, the connecting rod and the connecting rod mounting seat, the connecting rod and the special-shaped crank, the special-shaped crank and the connecting seat, and the special-shaped crank and the chuck are connected through bolts and nuts.
Preferably, the surface of the chuck is provided with a nylon plate.
The utility model has the advantages that:
1. the bearing is integrally assembled, so that the process steps of bearing assembly are simplified, and the assembly efficiency is greatly improved.
2. Connecting rod, special-shaped crank, connecting seat, chuck have constituted a slider-crank mechanism, the three slider-crank mechanism of the even distribution of MW level permanent magnetism direct drive generator bearing assembly fixture circumference for three chuck radially produces even clamping-force, realizes the centre gripping to the bearing, and can guarantee the dead weight auto-lock, ensures the security of assembling process.

Detailed Description
The utility model discloses when using:
1. before operation, the MW-level permanent magnet direct-drive generator bearing assembly tool is hoisted to the axis position of the bearing inner ring by using a gantry crane, and then a hoisting ring at the top of a hoisting rod is hoisted, so that the bearing inner ring is clamped by three chucks.
2. And hoisting the bearing to the position right above the shaft to be mounted, and slowly lowering the bearing to enable the bearing to be coaxial with the mounting surface of the shaft. And continuing to slowly drop the bearing, and rotating the bearing while dropping until the bearing is installed in place.
3. The hoisting ring at the top of the hoisting rod is lightly knocked to separate the chuck from the bearing inner ring, then a hoisting screw of the MW-level permanent magnet direct-drive generator bearing assembly tool is hoisted, and the MW-level permanent magnet direct-drive generator bearing assembly tool is hoisted away from the assembly area until the bearing assembly is finished.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
