Description
[technical field]
The utility model relates to the bearing test of mechanical field, relates in particular to a kind of staring torque after the wind-power electricity generation pivoting support assembles and assembles and pivoting support torsion-testing machine that moment of friction detects, play detects of being used for.
[background technology]
The quick growth of wind-powered electricity generation industry is for the development of wind power equipment provides strong guarantee.Over nearly 10 years, Chinese large-sized wind-powered electricity generation unit manufacturing industry starts from scratch, and begins to take shape at present.Country has more put into effect some concrete industrialization support policies, wherein proposes the wind power equipment localization rate of parts and components and will reach more than 70%, and the wind energy turbine set that does not satisfy the requirement of home-made equipment rate does not allow to build.Under this policy guide, more domestic large enterprises march the wind power equipment industry one after another, and the enterprise that was engaged in the wind power equipment manufacturing in 2006 has reached 30 families, have large quantities of enterprises to enter wherein again in 2007.The localization rate of parts and components of wind power equipment also improves constantly, 2004 be 25%, 2005 year nearly 30%, 2006 year be 40%, the Eleventh Five-Year Plan end is expected to reach more than 70%.
The pivoting support loading amount of minimum needs in every typhoon power generator group: driftage bearing 1 cover, pitch variable bearings 3 covers.Because the stressing conditions complexity of wind power bearing (driftage bearing, pitch variable bearings), and the shock and vibration that bearing bears are bigger, therefore, require bearing to withstand shocks, and can bear big load again.Aerogenerator main frame life requirements 20 years, the cost of Bearing Installation is bigger, and each dismounting need spend the expense of hundreds thousand of units, therefore requires driftage, pitch variable bearings life-span also will reach 20 years.Aerogenerator may be operated in extremely cold area, and environment temperature is low to moderate about-40 ℃, and the working temperature of bearing is low to moderate about-20 ℃, and bearing must can bear big shock load under cryogenic conditions.(bearing clearance is called the bearing clearance again, is meant bearing when not being installed on axle or bearing housing, and a side of its inner ring or outer ring is fixing, the amount of movement when then a loose side being done radially or moving axially at play for driftage, pitch variable bearings.) there is special requirement the aspect.With respect to the driftage bearing, the shock load of pitch variable bearings is bigger, and wind vibrations to the blade are also big, so require the play of pitch variable bearings to should be zero windage or negative gap value a little, can reduce the fretting wear of bearing like this under the situation of vibrations.The driftage bearing requires to be little play value.
