Description
Technical field
The present invention relates to a kind of driftage bearing on the aerogenerator and the measurement mechanism and measuring method of pitch variable bearings of being used for, be specifically related to a kind of measurement mechanism and measuring method of position of mounting hole of large slewing bearing.
Background technology
China is marching this piece of wind-power electricity generation brand-new " pollution-free industry ", in order to make aerogenerator promote generating efficiency, increase generated energy, the size at positions such as the length of blade, main shaft, speed-increasing gear, generator is also in continuous expansion, but the loading that the while bearing is born also increases gradually, and this technical requirement to wind power bearing is very high.Pitch variable bearings on the aerogenerator and driftage bearing are four-point contact ball formula ball bearing and double-row angular contact bal bearing, channel dimensions, position accuracy demand height, and it has higher quiescent load ability.Pitch variable bearings is mainly used in the adjusting vane angle and guarantees that blade rotational speed is constant, and band internal tooth and anodontia two kinds of structures are arranged, and slewing area is at 0～90 °, normally in 0～25 ° of scope.The driftage bearing is the assurance that aerogenerator is followed the trail of wind direction levelling head-on wind, bearing outer ring band tooth, and 360 ° of slewing areas, rotational frequency is the highest on 90 ° of scopes.To about the 3500mm, the pitch variable bearings and the driftage bearing that are used on the aerogenerator surmount this size to the diameter of the general usable range of super-huge pivoting support greatly, belong to supersize pivoting support bearing at 1000mm.Driftage and pitch variable bearings are according to installation requirement, and the position degree of general mounting hole requires about 0.05～0.06mm.The measurement of position of mounting hole can realize on three-coordinates measuring machine on the existing pivoting support bearing.Because wind-power generating yaw and pitch variable bearings diameter dimension are excessive: the yaw axis bearing outer-ring mounting hole center circle diameter on the 1.5MW aerogenerator is Φ 2436mm, inner ring mounting hole center circle diameter is Φ 2215mm, 1.5MW the pitch variable bearings outer ring mounting hole center circle diameter on the aerogenerator is Φ 2000mm, inner ring mounting hole center circle diameter is Φ 1800mm.Whether so large-scale pivoting support bearing is as if still adopting three-coordinates measuring machine to measure, and then the price of surveying instrument is very expensive, makes production cost rise, and adopt the three-coordinates measuring machine measurement can not measure single mounting hole and tilt.For this reason, needing to demand the measurement mechanism of a kind of special use of development urgently.
Summary of the invention
