Description
Technical field
The invention belongs to technical field of wind power generation, particularly relate to a kind of can the disassembly and assembly structure of spot replace motor bearings.
Background technology
Generator of wind generating set is positioned at set engine room inside, and on-the-spot cabin is stood on the high tower cylinder of 70m or 80m.Because the factor such as load, friction causes dynamo bearing to damage during unit running.The objective factor restrictions such as on-the-spot height and space, to observing the degree of wear of dynamo bearing and changing dynamo bearing generation great difficulty, cannot change in high-altitude and narrow space, even again lift generator sometimes, workload is large, and wastes a large amount of manpower and financial resources.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of can the disassembly and assembly structure of spot replace motor bearings.It can dismounting motor bearings in high-altitude and narrow and small cabin at the scene, is convenient to observe its degree of wear.
The object of the invention is to be achieved through the following technical solutions:
The present invention is a kind of can the disassembly and assembly structure of spot replace motor bearings, comprise temporary support, split type ring-type parallels and the dismantled and assembled motor of bearing, the dismantled and assembled motor of described bearing comprises generator ' s cover, main shaft, bearing, bearing pedestal, it is interference fit between its main shaft and bearing, when dismounting, temporary support one end is sleeved on main shaft, and the other end is connected with generator ' s cover, after dismounting bearing and bearing pedestal, the split type ring-type parallels arranging suit between generator ' s cover and main shaft supports generator ' s cover.
Further, described split type ring-type parallels forms circular ring structure by least 2 sector structures are assembled, and the annulus radical length of its ring-type parallels is identical to the distance of generator ' s cover end with main shaft.
Further, described temporary support is circular platform type tube-in-tube structure, respectively fixed main shaft horizontal direction and the vertical direction between generator ' s cover and main shaft.
Further, described circular platform type tube-in-tube structure is spoke type structure.
Beneficial effect of the present invention is:
1. the present invention can carry out on-the-spot disassembling, assembling and replacing to the front and back end bearing of generator, and can change dynamo bearing in high-altitude and narrow and small cabin at the scene, is convenient to observe its degree of wear, saves resource greatly, decrease labour intensity and the lifting fund of workman.
2. the present invention is by fixed generator end cap and main shaft, dismounting and installation bearing process, causes this work of spot replace dynamo bearing to be accomplished.While reduction labor strength and resource, solve on-the-spot difficulty easily and fast.
Accompanying drawing explanation
Fig. 1 is disassembly and assembly structure of the present invention and unloading process schematic diagram.
Fig. 2 is generator mounting structure schematic diagram in the present invention.
In figure: 1. temporary support, 2. generator ' s cover, 3. main shaft, 4. bearing pedestal, 5. ring-type parallels, 6. bearing, 7. bolt hole, 8. bearing inner ring, 9. bearing (ball) cover.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment: the present invention includes temporary support 1, split type ring-type parallels 5 and the dismantled and assembled motor of bearing, the dismantled and assembled motor of described bearing comprises generator ' s cover 2, main shaft 3, bearing 6 and bearing pedestal 4, be interference fit between its main shaft 3 and bearing 6, when dismounting, temporary support 1 is sleeved on main shaft 3, the other end is connected with generator ' s cover 2, and after dismounting bearing 6 and bearing pedestal 4, the split type ring-type parallels 5 arranging suit between generator ' s cover 2 and main shaft 3 supports generator ' s cover 2.
As shown in Figure 2, split type ring-type parallels 5 described in the present invention forms circular ring structure by least 2 sector structures are assembled, and the annulus radical length of its ring-type parallels 5 is identical to the distance of generator ' s cover 2 end with main shaft 3.As shown in Figure 1, described temporary support is circular platform type tube-in-tube structure or spoke type circular platform type tube-in-tube structure; Fixed main shaft horizontal direction and the vertical direction between generator ' s cover 2 and main shaft 3 respectively.Temporary support 1 is provided with multiple screw, and the bolt hole 7 reserved with generator ' s cover 2 is connected.
As shown in Figure 1, when on-site generated power machine bearing 6 needs dismounting, first, be set with in one end of temporary support 1 and main shaft 3, the other end adopts with generator ' s cover 2 and is threaded, thus reach to make when laying down motor bearings 6 main shaft 3 and generator ' s cover 2 temporary fixed.Secondly, bearing 6, bearing pedestal 4 and bearing (ball) cover 9 are moved integrally exit, then, pull down bearing inner ring 8 to exit, after bearing 6 exits completely, in order to more firmly support, the corresponding split type ring-type parallels 5 of size be set between main shaft 3 and generator ' s cover 2 and substitute, completing the unloading process of bearing.
As shown in Figure 2, during mounted motor bearing 6, get out bearing 6 to be installed, dismantle split type ring-type parallels 5, according to normal procedure, bearing 6 is installed fixing, after bearing 6 integral installation, lay down temporary support 1, complete the replacing installation process of bearing 6.
