Abstract
The utility model relates to a high stability wind power bearing, which comprises an outer ring (1), a roller (2) and an inner ring (3). The bearing inner ring (3) is provided with two integral flanges. One side of the outer ring (1) is provided with an integral flange. The high stability wind power bearing is characterized in that the other side of the outer ring (1) is provided with a stop ring (4); and an angle between the flanges and a raceway is between 90.05 and 90.1 degrees. The wind power bearing has high stability and long service life and can be suitable for harsh using working condition of a wind generating set. The roller is designed to be of a logarithm bus shape and provides the optimum stress distribution in a contact area of the wind power bearing so as to prolong the service life of the wind power bearing.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of wind power bearing of high stability.
Background technique
Wind power generating set generally is installed in wind-force such as inside and outside, wilderness, mountain pass, the seashore area of have no occluder more greatly and on every side, unit and inner Bearing Installation are in the high-altitude of tens meters or even 100 meters overhead, be subjected to the influence of the heat and the extreme temperature difference, running environment is abominable throughout the year.Have inconvenient traffic, maintenance is difficulty and with high costs very.In a single day bearing breaks down, and whole wind power generating set will be paralysed, and has a strong impact on the economic benefit of wind field.Generally all stable bad at the mal-condition lower bearing at present, working life is very short.
Summary of the invention
Bad for solving wind power bearing stability under mal-condition, the problem that working life is short, the utility model provides a kind of can adapt to abominable applying working condition, long-life high stability wind power bearing.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of high stability wind power bearing, comprise outer ring, roller, inner ring, bearing inner race has two whole ribs, and outer ring one side has a whole rib, it is characterized in that: described outer ring opposite side is provided with stop ring, and angle is between 90.05 degree are spent to 90.1 between rib and the raceway.Described roller is a logarithm shape shape.
The beneficial effects of the utility model are: this wind power bearing good stability, and working life is very long, can bear very heavy radial load, can adapt to the abominable applying working condition of wind power generating set; Roller designs becomes logarithm shape shape, provides optimum stress to distribute in the contact area of bearing, thereby improves bearing working life.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
A kind of high stability wind power bearing comprises outer ring 1, roller 2, inner ring 3, and bearing inner race 3 has two whole ribs, and outer ring 1 one sides have a whole rib, and outer ring 1 opposite side is provided with stop ring 4, by stop ring 4 bearing unit is fixed together.The roller of this wind power bearing adopts cylindrical roller, saves the space of the retainer of isolating roller 2, the more roller 2 of can packing in wind power bearing inside, and roller quantity is many than the roller bearing of normal tape retainer, therefore can bear very heavy radial load.Roller 2 quantity are many, do not isolate between the roller 2, and unidimensional relatively band retainer type roller bearing motion speed reduces, but by angle between research rib and the raceway, are about to it and are controlled between 90.05 to 90.1 °; Contact conditions between roller end face and the lasso rib is that the ball basal plane contacts with the awl rib; This wind power bearing can bear a thrust load on the direction and the axially locating of axle is provided in one direction.By suitable axial internal clearance is provided, be used for satisfying axle with respect to the small axial displacement of bearing support, for example because the axial displacement that the thermal expansion of axle causes etc.Roller 2 is critical components wherein, is designed to so-called logarithm shape shape, provides optimum stress to distribute in the contact area of wind power bearing, thereby improves wind power bearing working life, adapting to abominable applying working condition.
Claims (2)
1. high stability wind power bearing, comprise outer ring (1), roller (2), inner ring (3), bearing inner race (3) has two whole ribs, outer ring (1) one side has a whole rib, it is characterized in that: described outer ring (1) opposite side is provided with stop ring (4), and angle is between 90.05 degree are spent to 90.1 between rib and the raceway.
2. according to the described high stability wind power bearing of claim 1, it is characterized in that: described roller (2) is for logarithm shape shape.
