The wind-driven generator pitch variable bearings will bear load complicated and changeable when work, and the load ratio of bearing is bigger, 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, under the situation of vibrations, can reduce the fretting wear of bearing like this.
For pitch variable bearings, the requirement of play is zero windage or negative play a little.And for the measuring method of play, never a simple practical again measurement mechanism can be for reference.
Method relatively more commonly used at present is: the bearing that assembles is erected outer collar with cushion block, and the below is detected axial displacement with lifting jack roof pressure inside race with dial gauge, promptly draws the play value; But the method is comparatively loaded down with trivial details, and general moment of torsion detects assembly machine can't satisfy its requirement, need test separately, wastes time with artificial, influences efficient.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of time saving and energy saving, simple in structure feasible aerogenerator bearing clearance measurement mechanism, but the strict guarantee bearing does not have positive play, thereby guarantees that the every performance of bearing meets the demands.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises fuel tank, assembly machine work platform, be arranged on the assembly machine work platform inner ring and with the suitable outer ring of inner ring, be provided with dial gauge between inner ring and the outer ring, the inner ring below is provided with many push rods, one end of push rod is connected with hydraulic cylinder, and it stretches hydraulic cylinder by electric control system controls.Can guarantee that bearing clearance is zero or negative play a little, thereby guarantee that the every performance of bearing meets the demands.
Above-mentioned electric-control system comprises the control panel of oil pump, motor and the positive and negative motion of control motor, and oil pump is connected with motor, and motor is connected with control panel.
Above-mentioned hydraulic cylinder is connected with fuel tank by hydraulic line.
Above-mentioned push rod is provided with three, and is separately positioned on the inner ring trisection posistion.Make the inner ring stress balance.
The gauge stand of above-mentioned dial gauge is arranged on the outer ring upper surface, and the top-of-form set of described dial gauge is at the upper surface of inner ring.
The comparatively easy measurement that just can finish bearing clearance of the utility model mainly is the measurement of end-play, can guarantee that bearing clearance is zero or negative play a little, thereby guarantee that the every performance of bearing meets the demands.And the utility model is measured easy, the simple possible of bearing clearance, does not take that other is artificial, only can finish the measurement of play with a small amount of man-hour, and the strict guarantee bearing does not have positive play.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, the utility model comprises steel ball 11, fuel tank 10, assembly machine work platform 5, is arranged on inner ring 2 and outer ring 1 and electric-control system on the assembly machine work platform 5, on the upper surface of outer ring 1, be provided with the gauge stand 3 of dial gauge, on the upper surface of inner ring 2, be provided with the gauge outfit 4 of dial gauge.
Trisection posistion below inner ring 2 is respectively arranged with a push rod 9, and the lower end of push rod 9 is connected with a hydraulic cylinder 6 respectively; It stretches hydraulic cylinder 6 by electric control system controls.
Electric-control system comprises the control panel (not marking among the figure) of motor (not marking among the figure), oil pump 7 and the positive and negative motion of control motor, and motor is connected with oil pump 7, and control panel is connected with motor by cable; Fuel tank 10 is connected with hydraulic cylinder 6 by hydraulic line 8.Directly control three hydraulic cylinders 6 fuel feeding simultaneously by control panel, rise push rod 9 simultaneously, detect inner ring 2 axial displacements, promptly draw the play value with dial gauge.
But the motor rotating, the break-make of oil pump 7 control oil channel during motor action.When control panel control motor was just changeing, oil pump 7 forwards were connected, and the hydraulic oil in the fuel tank 10 enters hydraulic cylinder 6 by hydraulic line 8, and push rod 9 ejects, can be to the measurement of bearing clearance.
When the counter-rotating of control panel control motor, oil pump 7 is oppositely connected, and the hydraulic oil in the hydraulic cylinder 6 is got back to fuel tank 10 by hydraulic line 8.The utility model is realized Long-distance Control hydraulic cylinder 6 by electric-control system, again the flexible measurement that has realized bearing clearance by hydraulic cylinder 6.
The utility model is measured according to following step:
(A) outer ring 1 is placed on the assembly machine work platform 5, carries out the school circle; Guarantee that 1 center, outer ring overlaps with assembly machine work platform 5 centers.
(B) inner ring 2 is hung on assembly machine work platform 5, and inner ring 2 is connected with outer ring 1 by steel ball 11, and inner ring 2 do not contact with assembly machine work platform 5, adjustment steel ball 11 sizes satisfy the final finished measurement requirement;
(C) trisection posistion is provided with a push rod 9 respectively below inner ring 2, connects a hydraulic cylinder 6 respectively in the lower end of push rod 9, and hydraulic cylinder 6 is flexible by electric control system controls push rod 9;
