Description
Technical field
The utility model relates to a kind of epicyclic gearbox supporting base, more specifically to a kind of combined support seat of wind-powered electricity generation bracket loading test platform epicyclic gearbox.
Background technique
Wind power speed-increasing gearbox is the core component of wind power generating set, be arranged on the air port places such as high mountain, wilderness, seabeach, island due to wind power generating set, impacted by irregular break-in, the effect of varying duty wind-force and strong gusts of wind, the requirement in its reliability and working life is more high than common mechanical.Because wind-powered electricity generation unit load condition is complicated and changeable, when wind turbine gearbox operation, operating mode is very complicated.Wind-powered electricity generation industry is emerging industry, and industry starting and technical research time are all more late, and correlation technique theory is all gone back imperfection, and basic data data deficiencies does not have ripe especially high-power wind turbine gear-box product both at home and abroad.Load test is the necessary means of gear-box research and development and quality testing, and high-power bracket loading test platform almost becomes the bottleneck of restriction high-power wind turbine gear-box research and development.Research and development for high-power wind turbine gear box test table will contribute to the research and development of domestic megawatt wind power gear case and the raising of quality of product.For the strict demand in the reliability to wind turbine gearbox and life-span, gear-box is carried out to the important step that load test test is wind turbine gearbox exploitation, design and production.Wind turbine gearbox bracket loading test platform can be realized driving and the loading to wind turbine gearbox, completes the various tests of gear-box, the working state of simulation gear-box in the time of wind-power electricity generation.Along with the rapid growth of wind-powered electricity generation capacity of power unit, also rapid growth of the rated power of wind turbine gearbox and test stand thereof, therefore stricter to the requirement of wind turbine gearbox test stand, the development difficulty of test stand also further improves.This has higher requirement to the supporting base that supports high-power planet main-gear box on test stand and use, require supporting base good rigidity, be not easy distortion, wear-resistant, can bear wind turbine gearbox complete machine weight and dynamic load, and be convenient to repeatedly to install, the adjustment of dismounting and all directions.But existing supporting base can not meet these requirements.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of combined support seat of epicyclic gearbox, and to solve repeatedly attaching/detaching of prior art middle gear case supporting base inconvenience, easily wearing and tearing, distortion, be difficult for carrying out the problems such as centering adjustment in all directions.
To achieve these goals, the technical solution of the utility model is:
A combined support seat for epicyclic gearbox, comprising: base plate, undersetting, upper bracket, lining and baffle plate.Described base plate is packed on the support of test stand; Described undersetting is interval with two, is all welded on base plate, is all formed with semi-circular hole on each undersetting top; On each undersetting, be respectively installed with a upper bracket by link, the bottom of upper bracket is formed with semi-circular hole, and this semi-circular hole is corresponding with the semi-circular hole on undersetting top, and hanger is installed on upper bracket; In each described semi-circular hole, lining is all installed, is all provided with at the semi-circular hole two ends of upper and lower bearing and prevents the lining baffle plate of semicircle annular in axial sliding.
Preferably, the compound rubber pad of a semicircular high strength is also installed in each lining.
Preferably, between described undersetting and upper bracket, locate finger setting by one.
The utility model is compared with the advantage of prior art: epicyclic gearbox supporting base adopts fabricated structure, mainly combined by upper undersetting, can repeatedly mount and dismount easily, dynamic load when can bearing the gear-box complete machine weight being transmitted by gear-box toggle and testing, the good lining of wear resistance is installed respectively in the semicircle orifice of upper undersetting, even if go through like this after test of many times, wearing and tearing also only may there will be on lining instead of in the semicircle orifice of undersetting.Can ensure by resleeve more shape and the positional accuracy of upper and lower bearing hole.In addition, adopt the structure of combined support seat can in semicircular bush hole, place semicircle high-intensity compounded rubber pad, can be according to stressed automatic adjustment distortion, can effectively improve the installation precision of gear-box, and vibration-absorbing denoising, prevents the mechanical deterioration causing because local compression is excessive.On base plate four direction, be all processed with tapped hole, for passing through screw thread driving belt moving gear case supporting base integrated moving, so that after gear-box is arranged on supporting base, can be in the enterprising line position fine setting of all directions, to increase the centering in all directions between high speed shaft of gearbox and electric machine main shaft.

Embodiment
Below in conjunction with accompanying drawing, the structure of supporting base of the present utility model is elaborated.
As shown in the figure, this supporting base comprises: base plate 1, undersetting 2, upper bracket 3, lining 4 and baffle plate 5.Described base plate 1 is fixed on by fastening piece 9 on the support of test stand; Two undersettings 2 are all welded on base plate 1; Be formed with corresponding semi-circular hole on undersetting 2 tops and upper bracket 3 bottoms, in two semi-circular hole, lining 4 be all installed, the baffle plate 9 of semicircle annular is all installed at the semi-circular hole two ends of upper and lower bearing 2,3, to prevent sliding axially of lining 4.The both ends of the surface of undersetting 4, upper bracket 3 are all provided with baffle plate 5 by screw 8, to ensure the axially locating of lining 4.A compound rubber pad of semicircular high strength can also be installed, to guarantee the accuracy of installing and to prevent mechanical deterioration in the hole of each lining 4.Hanger 10 is installed on upper bracket 3; Between undersetting 2 and upper bracket 3, locate by locating stud 6, guarantee installation precision.Upper bracket 3 by link 7, for example, is packed on undersetting 2 by connecting screw rod, pad and nut.As shown in Figure 4, when test stand work, need two such gear-box supporting bases to carry out the corresponding part of support teeth roller box toggle.
