Abstract
A turnplate bearing of three-line equant cylindrical roller type disclosed by the utility model relates to the technical field of the bearing of a wind-driven generator, which comprises a seat ring, a first shaft ring, a second shaft ring, a sealing ring, rolling bodies, a first cage seat, a first cage cover and a second cage, wherein the first cage seat is connected with the first cage covert through a bolt; the first cage seat and the first cage cover are arranged on a raceway of the second shaft ring; the first cage seat and the first cage cover form a first cage; the rolling bodies are respectively arranged in pockets of the first cage and the second cage; the first cage is arranged onto the upper raceway of a seat ring; the first shaft ring is arranged on the second shaft ring; and the sealing ring is arranged between the seat ring and the first shaft ring. The bearing disclosed by the utility model can bear the weight of blades and a hub and the axial force, the radial force and the upsetting moment, which are generated when wind blows the blades.
Description
Technical field
The utility model relates to the wind-driven generator technical field of bearings, is specifically related to the isometrical cylindrical roller formula turntable bearing of a kind of three rows.
Background technique
Wind energy power is as green energy resource and renewable energy sources, is to improve energy resource structure, preserve the ecological environment, and implements the effective means of energy field sustainable development.The components supplying chain of whole world blower fan is tending towards nervous, wherein nervous with bearing and blade again, state outer bearing price is high and supply untimelyly, and domestic manufacturers still fail self-sufficient, and the price of imported bearing and lead time have all seriously restricted China's blower fan process of localization.
Along with the continuous development of China's wind-power electricity generation cause, high-power direct-drive aerogenerator becomes development trend, and it has avoided the problem of double-feedback aerogenerator speedup box rate of fault height and electric quantity loss
Therefore,, be badly in need of a kind of novel driftage bearing is provided, supporting the whole cabin of wind-driven generator, bearing axial force, radial force and tilting moment that the inswept blade of wind produces simultaneously in order to satisfy the requirement of 3MW direct-drive aerogenerator.
The model utility content
The purpose of this utility model provides the isometrical cylindrical roller formula turntable bearing of a kind of three rows, and it can bear axial force, radial force and tilting moment that the inswept blade of wind produces.
In order to achieve the above object, the technical solution of the utility model is as follows:
The isometrical cylindrical roller formula turntable bearing of a kind of three rows, this bearing comprises seat ring, first blowout patche, second blowout patche, seal ring, rolling element, first keeps stand, first retainer lid and second retainer, first keeps stand to be connected by screw with first retainer lid, first keeps stand and first retainer lid to be placed on the raceway of second blowout patche, first keeps stand and first retainer lid to form first retainer, rolling element is installed in respectively in the pocket hole of first retainer and second retainer, first retainer is placed on the top raceway of seat ring, first blowout patche places above second blowout patche, and seal ring places between the seat ring and first blowout patche.
The beneficial effects of the utility model are: this bearing can bear the weight and common huge axial force, radial force and the tilting moment that produces of the inswept blade of wind of wind power generator oar blade, wheel hub.The utility model is mainly used in high-power direct-drive aerogenerator yaw system.
Description of drawings
Fig. 1 is the structural representation of the isometrical cylindrical roller formula turntable bearing of the utility model three rows.
Wherein: 1, seat ring, 2, first blowout patche, 3, second blowout patche, 4, seal ring, 5, rolling element, 6, first keeps stand, 7, first retainer lid, 8, second retainer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in Figure 1, the isometrical cylindrical roller formula turntable bearing of three rows of the present utility model mainly keeps stand 6, first retainer lid, 7 and second retainer 8 to form by seat ring 1, first blowout patche 2, second blowout patche 3, seal ring 4, rolling element 5, first.
The rolling element 5 of three row's raceways of the present utility model all is made up of the double cylindrical roller of isometrical equal length, and the cylindrical roller of two isometrical equal lengths all is housed in each retainer pocket hole.
The assembly process of the isometrical cylindrical roller formula turntable bearing of the utility model three rows is as follows:
At first, keep stand 6 and first retainer lid, 7 usefulness screws to link into an integrated entity with first, again second blowout patche 3 is placed on the mountion plate, first keeps stand 6 and first retainer lid, 7 retainers that link into an integrated entity to be placed on the raceway of second blowout patche 3, two row rolling elements 5 is installed in first keeps in the pocket hole of stand 6; Then second retainer 8 and two row rolling elements 5 are formed an assembly, rolling element 5 need from top, below be installed in successively in the pocket hole of retainer, and position shown in the figure is installed; Again seat ring 1 is installed in shown position, then keeps stand 6 and first retainer lid, 7 retainers that link into an integrated entity to be placed on the top raceway of seat ring 1, two row rolling elements 5 are installed in first keep in the pocket hole of stand 6 first; First blowout patche 2 is installed at last at shown position.
One row's rolling element on bearing top is used to bear axial force and tilting moment, and row's rolling element of bottom is used to bear axial force, and middle radial rolling body is used for bearing radial force.
The cylindrical roller of double isometrical equal length all is housed respectively on the raceway of thrust up and down of the utility model bearing, has avoided single long cylinder roller when bearing heavy duty, to produce warpage, cause the bearing premature damage, can bear huge axial force and tilting moment; Radially raceway is equipped with the cylindrical roller of double isometrical equal length, can bear huge radial force.
