Abstract
The invention discloses a transmission shaft rolling type axial supporting device comprising transmission shafts, the supporting device comprises a plurality of rolling components cycle arranging and fixed connecting on the transmission shaft end faces of the same structure, a plurality of rolling components can roll along the same plane and include bearing pedestals fixed connecting with the transmission shafts, supporting shafts arranged on the bearing pedestals and rolling bearings arranged on the supporting shafts, the supporting shafts and the transmission shaft end faces are mounted on the bearing pedestals with inclined shape. When using, a plurality of rolling components are cycle arranged and connected on the transmission shaft end faces to make the taper sleeve of the rolling components joint with the axial force bearing device of the wind motor. The device is composed of a plurality of rolling components which have simple structure, shrort processing cycle, low manufacturing cost, so that, the device has shorter processing cycle and lower manufacturing cost relative to the large scale traditional thrust bearing.
Description
Technical field
The present invention relates to a kind of roller axial supporting device for driving shaft.
Background technology
At present, high-power grid type wind-driven generator is along with continuous advancement in technology, and single-machine capacity is increasing, and the volume and weight of unit increases thereupon, and the diameter of its power transmission shaft is also increasing.In order to bear the axial force of power transmission shaft, need on power transmission shaft, adorn the very big traditional thrust bearing of specification, this big specification thrust bearing complex manufacturing technology, the manufacturing cycle is long, and the cost height is seriously restricting the manufacturing speed and the production cost of large-scale wind driven generator.
Summary of the invention
The technical problem to be solved in the present invention is at above-mentioned defective, and a kind of roller axial supporting device for driving shaft that can replace traditional thrust bearing that the large-scale wind driven generator power transmission shaft is used that is suitable for is provided, and this device can shorten the manufacturing cycle, reduces production costs.
For solving the problems of the technologies described above, the invention provides a kind of roller axial supporting device for driving shaft of following structure, comprise power transmission shaft, its design feature is: this bracing or strutting arrangement comprises the many groups of rolling assemblies that are fixed on the power transmission shaft end face that structure is identical, described many group rolling assemblies are distributed on the identical graduation circle, each group rolling assembly comprises the bearing pedestal affixed with power transmission shaft, be contained in back shaft and the rolling bearing that is contained on the back shaft on the bearing pedestal, back shaft is skewed and is contained on the bearing pedestal, the end that back shaft is far away apart from the power transmission shaft axle center and the distance of power transmission shaft end face are less than the near end in distance power transmission shaft axle center, be set with conical sleeve on the rolling bearing, the tapering of conical sleeve is identical with the angle of inclination of back shaft, and the big end of the diameter of conical sleeve is away from the power transmission shaft axle center.
The roller axial supporting device for driving shaft of said structure during use is periphery many group rolling assemblies and is fixed on the end face of power transmission shaft, the axial force holder of the conical sleeve of many group rolling assemblies and wind-driven generator is adjacent to gets final product.Because this bracing or strutting arrangement is made of many groups rolling assembly, rolling assembly is simple in structure, and the process-cycle is short, low cost of manufacture, thereby can make this bracing or strutting arrangement for traditional thrust bearing of big specification, its process-cycle is short, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
Roller axial supporting device for driving shaft as depicted in figs. 1 and 2 comprises the rolling assembly 1 on many groups of identical power transmission shaft 2 end faces that are periphery and are fixed in of structure, and described many group rolling assemblies 1 can be along same plane rolling.Rolling assembly 1 shown in the figure is six groups, and the number of rolling assembly 1 is decided according to the diameter and the stressing conditions of power transmission shaft 2, and along with the diameter of power transmission shaft and stressed increase, the number of rolling assembly 1 also increases thereupon.Six groups of rolling assemblies 1 are distributed on the identical graduation circle.Each group rolling assembly 1 comprises the bearing pedestal 1-1 affixed with power transmission shaft, is contained in the back shaft 1-2 on the bearing pedestal 1-1 and is contained in rolling bearing 1-3 on the back shaft 1-2, back shaft 1-2 is skewed and is contained on the bearing pedestal 1-1, the distance that is back shaft 1-2 end far away apart from power transmission shaft 2 axle center and power transmission shaft 2 end faces is less than the near end in distance power transmission shaft 2 axle center, be set with conical sleeve 1-4 on the rolling bearing 1-3, the tapering of conical sleeve 14 is identical with the angle of inclination of back shaft 1-2, and the big end of the diameter of conical sleeve 1-4 is away from power transmission shaft 2 axle center.Each group rolling assembly 1 is fixed on power transmission shaft 2 end faces by bolt by bearing pedestal 1-1.Can be provided with axial force receiving plate 3 in the casing of wind-driven generator, will guarantee that the outer surface of conical sleeve 1-4 and receiving plate 3 are adjacent to during assembling power transmission shaft 2, this receiving plate 3 can be provided with the casing inner wall that also can utilize wind-driven generator separately.
The present invention not only can be used for the power transmission shaft of large-scale wind driven generator, also can be used for the power transmission shaft of other main equipments.
