Abstract
The utility model relates to a bearing retainer, in particular to a one-piece entity retainer structure of a high-speed end bearing for a booster engine of a wind driven generator. The retainer is a one-piece structure, a plurality of pockets are arranged on the retainer, and slope structures are adopted at the lower ends of the pockets. Compared with other similar technical products, the retainer enables the bearing adopting the retainer to well bear axial loads under the high-end high speed condition of the booster engine; and meanwhile, the retainer has light weight, which is beneficial to high-speed rotation, and the reliability of the fan booster engine is increased.
Description
Technical fieldThe utility model relates to a kind of retainer, specifically relates to be applied to the integral type solid cage structure of a kind of wind-driven generator speed increasing engine speed end bearing of wind power generation driving system.
Background techniqueWind 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 obvious with the application of 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.
At present, all rely on external import from 1.5MW to 5.0MW blower fan booster engine speed end bearing, produce blower fan in enormous quantities, key components and parts does not have the core technology of oneself, and Chinese blower fan development cost will be huge.So the research and development ability deficiency of booster engine speed end bearing is a major obstacle of current state inner blower gear-box development.
Summary of the inventionThe utility model is in order to remedy above-mentioned technological deficiency, a kind of integral type solid cage structure of wind-driven generator speed increasing engine speed end bearing to be provided.
To achieve these goals; The technological scheme of the utility model is: the integral type solid cage structure of wind-driven generator speed increasing engine speed end bearing; It is characterized in that described retainer adopts integral type entity copper retainer; Comprise some pockets hole on the retainer, ramp structure is adopted in lower end, described pocket hole.
This model utility is simple in structure, adopts integral type, and retainer is selected copper material for use, makes to adopt the bearing of this retainer under the situation of the high-end high speed of booster engine, well to bear thrust load; Simultaneously, this retainer is in light weight, more helps high speed rotating, improves the reliability of blower fan booster engine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, retainer, 2, the pocket hole.
Embodiment
Fig. 1 shows a kind of integral type solid cage structural representation of wind-driven generator speed increasing engine speed end bearing.Among the figure, described retainer adopts integral type entity copper retainer structure, and in light weight, external diameter is made the oblique angle, more helps the formation of oil film under the fast state; Comprise some pockets hole on the retainer, ramp structure is adopted in lower end, described pocket hole, helps installing and the bearing high speed rotating.
Described retainer assembly process is:
The outer assembly of first cover at first is installed: the outer ring is lain on the mountion plate, retainer is contained on the raceway of outer ring, the composition rolling element is packed in the pocket hole of retainer; Then, inner ring is lain on the platform, outer assembly is packed into from the upper end; Again inner ring is installed to the outer assembly outside.
Claims (2)
