Abstract
The utility model relates to a wind power vane testing device which comprises a frame with a mounting hole, a variable pitch bearing disposed in the mounting hole and a switch over disc connected to an inner ring flange of the variable pitch bearing. The switch over disc is used for being connected with a wind power vane base. An inner ring of the variable pitch bearing is an inner ring gear. An output shaft of a hydraulic motor which is fixedly connected with the frame is meshed with the inner ring gear. During operation, the hydraulic motor drives the variable pitch bearing to rotate through gear transmission, namely pitch variation is performed to the vane. Due to the fact that the hydraulic motor is provided with a brake, pitch variation can be stopped at any position. The wind power vane testing device is simple in structure and high in reliability.
Description
Technical field
The utility model relates to the technical field of carrying out torture test and strength testing facility for the standard specimen that the wind electricity blade material is made, specifically a kind of test unit that is suitable for the wind electricity blade rotation.
Background technology
In prior art, when the standard specimen that the wind electricity blade material is made carries out torture test and strength test, need to overturn to blade.Lack corresponding equipment in prior art.Therefore, how to provide a kind of and be suitable for when carrying out the strength test of wind electricity blade, the device of the blade that is suitable for overturning to realize the related experiment purpose, is the technical matters of this area.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of wind electricity blade test unit of simple in structure, the blade that is suitable for overturning.
For solving the problems of the technologies described above, the utility model provides a kind of wind electricity blade test unit, it comprises: with the frame of mounting hole, be located at the pitch variable bearings in described mounting hole, be connected to transfer panel on the inner ring flange of this pitch variable bearings, that be used for connecting the wind electricity blade base, the inner ring of described pitch variable bearings is ring gear, the output shaft of an oil motor that is fixedly connected with described frame and the engagement of described ring gear.
The utlity model has positive effect: in wind electricity blade test unit of the present utility model, blades installation is on transfer panel, transfer panel is arranged on the inner ring flange of pitch variable bearings, the outer ring flange of pitch variable bearings is bolted and is fixed on frame, the inner ring of pitch variable bearings is a ring gear, and oil motor drives the pitch variable bearings rotation by gear drive, namely blade is become oar,, stop the optional position again so become the oar motion with detent due to oil motor self; Therefore, wind electricity blade test unit of the present utility model has characteristics simple in structure, that reliability is higher.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of the wind electricity blade test unit in embodiment;
Fig. 2 is the end face structure schematic diagram of the pitch variable bearings in Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
See Fig. 1-3, the wind electricity blade test unit of the present embodiment comprises: with the frame 3 of mounting hole, be located at the pitch variable bearings 2 in described mounting hole, be connected to transfer panel 4 on the inner ring flange of this pitch variable bearings 2, that be used for connecting wind electricity blade 1 base, the inner ring of described pitch variable bearings 2 is ring gear, the output shaft of an oil motor that is fixedly connected with described frame 3 and the engagement of described ring gear.
During work, oil motor drives the pitch variable bearings rotation by gear drive, namely blade is become oar,, stops the optional position so become the oar motion with detent due to oil motor self again; Therefore, wind electricity blade test unit of the present utility model has characteristics simple in structure, that reliability is higher.
Above-described embodiment is only for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among protection domain of the present utility model.
