The assembling tool is applied to assembly between a spherical self-aligning roller bearing, an adjusting sleeve and the main shaft of the large permanent magnet direct-driven wind driven generator, and can provide positioning to assemble the bearing to an appointed position of the main shaft and obtain an appropriate bearing play. The tool is simple in structure, low in manufacturing cost, simple to use and beneficial to adjustment, and can ensure the demands of assembly effectively to meet the technical effect needed.
Description
Technical field
The present invention relates to technical field of wind power generation, particularly relate to a kind of bearing and spindle mounted frock of permanent magnet direct-driving aerogenerator.
Background technology
At present, wind-power electricity generation generator special forward high reliability, low maintenance, low cost, high efficiency future development.Following development trend has been become apart from the direct-drive permanent magnet wind power generator of adjustment, the slow-speed of revolution, high efficiency, High Power Factor based on variable-speed operation, change slurry.But direct-drive permanent magnet wind power generator is owing to being directly connected with wind energy conversion system, and its rotating speed is low, number of poles is many, stator, rotor, bearing size are large, bring the assembly problem of the heavy motor that can not be ignored thus.
For the large size bearing of clearance adjustable type, general with the assembling of dedicated hydraulic frock, by pressure, bearing is moved on taper sheath, to reach required play.This kind of scheme shortcoming to have special tooling, and costly, and different bearings will join different frocks.
As can be seen here, in prior art there is significantly not enough and defect in the assembly tooling of generator large size bearing in structure and use procedure, urgently improves further.Therefore, how to found and a kind ofly make bearing location and installation obtain suitable bearing clearance and the simple assembly tooling of structure, belong to one of important topic of current research and development in fact.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of bearing and spindle mounted frock of permanent magnet direct-driving aerogenerator, bearing orientation assemble can be made convenient, simple, and the manufacturing cost of frock is lower, thus overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above, the bearing of a kind of permanent magnet direct-driving aerogenerator of the present invention and spindle mounted frock, comprise base plate, location-plate and lower end and be fixedly connected with the supporter that upper end is fixedly connected with location-plate with base plate.
As a further improvement on the present invention, described supporter comprises pair of side plates and is fixed on the gripper shoe between biside plate.
Described location-plate comprises upper and lower one-sided arc plate, and wherein, the arc-shaped edges of upper and lower one-sided arc plate is all towards the inner side of assembly tooling, and upper one-sided arc plate is positioned at the upper outer of lower one-sided arc plate.
Described base plate is provided with two or more and installs through hole.
Described base plate outer edge is arc.
Described assembly tooling adopts Plate Welding to form.
After the present invention adopts above design, there is following beneficial effect compared with the prior art:
1, the present invention is applied to the spherical aligning roller bearing of large directly driven permanent magnet wind generating and the assembling between adjusting sleeve and main shaft, can provide location, and bearing assemble is obtained suitable bearing clearance to the assigned address of main shaft;
2, the present invention includes a whole set of frock of some groups of single-piece tooling combination compositions, single-piece tooling combination structure is simple, low cost of manufacture; Easy to use, be beneficial to adjustment, effectively can meet matching requirements, reach required technique effect.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solution of the present invention, and in order to better understand the present invention, below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Fig. 1 is the bearing of permanent magnet direct-driving aerogenerator of the present invention and the structural representation of spindle mounted frock.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the schematic diagram that the present invention is applied to the assembling of large-scale direct wind-driven generator group spherical aligning roller bearing.
Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2, the bearing of a kind of permanent magnet direct-driving aerogenerator of the present invention and spindle mounted frock, comprise base plate, location-plate and lower end and be fixedly connected with the supporter that upper end is fixedly connected with location-plate with base plate.
Further specifically, base plate 1 preferably outer edge is the shape of arc, and is arranged with two or more installation through hole at arc two ends.Supporter comprises pair of side plates 2 and is fixed on the gripper shoe 3 between biside plate 2, and the whole height of supporter adapts with needing the bearing axial location assembled.Location-plate comprises upper and lower one-sided arc plate, wherein, the arc-shaped edges of upper and lower one-sided arc plate is all towards the inner side of assembly tooling, and upper one-sided arc plate 4 is positioned at the upper outer of lower one-sided arc plate 5, the internal diameter of the bearing inner ring that the circular arc of upper one-sided arc plate 4 and needs assemble is suitable, and the circular arc of lower one-sided arc plate 5 is suitable with the external diameter of main shaft.Above-mentioned base plate 1, side plate 2, gripper shoe 3 and one-sided arc plate 4,5 all can adopt steel plate to make, and is welded to each other and is integrated, and do preservative treatment.
Shown in Fig. 3, when needing bearing holder (housing, cover) to be loaded on main shaft, need the bearing of multiple permanent magnet direct-driving aerogenerator of the present invention and spindle mounted frock with the use of.
First, main shaft 7 is vertically positioned over assigned address, then the circumference equal dividing of several assembly toolings of the present invention along main shaft 7 is arranged, and with the installation through hole on assembly tooling base plate 1, assembly tooling is fixedly connected with main shaft 7 by standard bolt 6.In installation process, the circular arc side of lower one-sided arc plate 5 contacts with the external diameter of main shaft 7.
Afterwards, coordinated with main shaft by taper sheath 8(internal diameter supporting for bearing, external diameter is taper) be sleeved on main shaft 7, the base of taper sheath 8 and the upper flat face of upper one-sided arc plate 5 touch.Be the conical surface by the bearing 9(bearing inner ring internal diameter being heated to suitable temperature again) be sleeved on taper sheath 8, make bearing 9 drop on above one-sided arc plate 4, bearing 9 can be fastened on bearing inner ring 8 after cooling, thus obtains the suitable axial location of bearing and play.
The adjustable axle that the present invention is applicable to satisfactory all high-rating generators to band of position cone locking overlap spherical roller self-aligning bearing and main shaft between orientation assemble, the external diameter size of the bearing that can assemble as required and main shaft chooses required frock size and number of combinations.
