Abstract

The invention relates to a misaligned arc pocket hole structure cage, and belongs to the field of bearings. The misaligned arc pocket hole structure cage consists of a frame and a pocket hole formed in the frame; the arc centers on two sides of the pocket hole and the roller center of a roller in the pocket hole are not in the same position; the arc center on the right side of the pocket hole is on the left side of the roller center; the arc center on the left side of the pocket hole is on the right side of the roller center; and the roller and the pocket hole are linearly contacted. The misaligned arc pocket hole structure cage largely increases oil film forming conditions, reduces the wear between the roller and the cage, and solves the problem of the cage scratching the roller.

Description

One decentraction circular arc pocket hole structure retainer
Technical field
The present invention relates to a kind of one decentraction circular arc pocket hole structure retainer, main application wind-powered electricity generation industry, is applicable on wind turbine gearbox speed end bearing.
Background technique
Wind turbine gearbox is very important parts in whole blower fan, and between wind turbine main shaft and generator, its effect is the high rotating speed slow-speed of revolution of wind wheel being changed into generator needs.Due to the huge spread between wind speed round and generator speed, gear-box is made to become requisite parts in double-feedback aerogenerator group.In the running of wind-driven generator, the force-bearing situation of wind wheel is very severe, needs to run continuously under sharply change-load, and the various load suffered by it are all directly passed to gear-box by main shaft.Gear-box stand under load is severe, and spoilage occupies first place.Therefore the bearing in gear-box is one of very important component in gear-box, especially concerning speed end bearing, must meet the highly reliable life-span of 20 years.
Show in all component of gear-box according to practical situations both domestic and external, bearing is one of the weakest link, and therefore each component of bearing just seem particularly important in structural design, manufacture etc.Wherein gearbox high-speed step bearing retainer in the process of running scratches the importance that roller is research always.
Summary of the invention
In the working environment of complexity, during retainer running, scratching the problem of roller in order to overcome wind turbine gearbox speed end bearing, the invention provides a kind of one decentraction circular arc pocket hole structure retainer.
The technological scheme that the present invention takes: a kind of one decentraction circular arc pocket hole structure retainer, be made up of support body and the pocket hole be located on support body, described Dou Kong both sides center of arc be contained in the roller centre of the roller in pocket hole not at same position, right side Dou Kong center of arc is in the center left of roller, left side Dou Kong center of arc is at the central right of roller, and the contact in roller and pocket hole is linear contact lay.
Beneficial effect of the present invention: the present invention compared with the existing technology has the condition greatly improving oil film and formed, and reduces the wearing and tearing between roller and retainer, solves the problem that retainer scratches roller.

Fig. 2 is the partial sectional view of the embodiment of the present invention;
In figure: 1, support body, 2, pocket hole, 3, roller, 4, right side Dou Kong center of arc, 5, left side Dou Kong center of arc, 6, roller centre.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described: the right side Dou Kong center of arc 4 in pocket hole 2 is in the center left of roller 3, and the left side Dou Kong center of arc 5 in pocket hole 2 is at the central right of roller 3, and roller 3 is linear contact lay with the contact in pocket hole 2.
