Abstract
The utility model relates to a fatigue testing device of a wind power generator variable pitch bearing. According to the fatigue testing device, a testing table (7) is installed on the upper portion of a base (1), a bearing seat (6) is installed on the side surface of the testing table (7), and a movable gear (5) is installed in the bearing seat (6). By means of a structure imitating a field industrial and mining load, load fatigue performances of the variable pitch bearing can be conveniently detected, manufacture, installation and using are convenient, the operation is simple and rapid during detection, the operation is stable and safe, performances are reliable, and the fatigue testing device is durable.
Description
Technical field
The utility model relates to big-diameter bearing proving installation technology, especially the wind-driven generator pitching bearing fatigue proving installation in wind power plant manufacturing field.
Background technology
The wind energy power technology development rapidly, unit manufactures and designs and day by day tends to high-power, the bearing that wind-driven generator is heavily used belongs to indispensable critical component too, its diameter is generally also larger, because bearing belongs to precise part, so, before dispatching from the factory, processing and manufacturing needs constantly detect and test, for example, the pitch variable bearings cycle of operation is long, load is large, so, the load testing fatigue of pitch variable bearings is very important, but, in prior art, find that not yet the isolated plant technology that is exclusively used in this class testing discloses.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of wind-driven generator pitching bearing fatigue proving installation, is convenient to pitch variable bearings is tested.
Realize that goal of the invention measure of the present utility model is: pedestal top installation testing platform, test board side installation shaft bearing is installed moving gear in bearing seat.
The utility model has the advantage of, adopt simulated field industrial and mineral support structures, the convenient load fatigue behaviour that detects pitch variable bearings, manufacturing, installation, easy to use, simple to operation during detection, operate steadily, safety, dependable performance is durable.
Description of drawings
Fig. 1 is structural representation of the present utility model
Mark comprises: pedestal 1, control device 2, load 3, pitch variable bearings 4, moving gear 5, bearing seat 6, test board 7.
Embodiment
As shown in Figure 1, pedestal 1 top installation testing platform 7, test board 7 side installation shaft bearings 6 are at the interior installation moving gear 5 of bearing seat 6.
In aforementioned, control device 2 is installed on pedestal 1.
In aforementioned, pedestal 1 top fixing test platform 7, bearing seat 6 axis and horizontal plane angle are less than 45
o
In aforementioned, pedestal 1 upper axis connecting test platform 7.
The utility model is when using, first with pitch variable bearings 4, be fixed on bearing seat 6, and with moving gear 5 and pitch variable bearings 4 inner ring gear engagements, then, then load 3 is installed to pitch variable bearings 4 outsides, starts control device 2, according to pitch variable bearings 4 performance change after setting test run one-period, to determine pitch variable bearings 4 load fatigue behaviours.
In above embodiment, do not reach the employing prior aries such as other necessary technologies that relate to enforcement of narration, enumerate no longer successively detailed description.
