Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 to Fig. 3, on a diameter is the center circle of d and d ', be provided with some mounting holes 10 in uniform way respectively on the inner ring of pivoting support bearing 1 and the cycle surface.
The measurement mechanism of the position of mounting hole of large slewing bearing of the present utility model comprises a template 2 and some measurements rod 3, wherein,
The quantity of measuring rod 3 is identical with the quantity of measured hole 20, each measurement rod 3 all contains a pole cap 30 and a bar portion 31, the outside surface of this bar portion 31 is the little stepped appearance in big bottom, a top, and the length of this bar portion 31 is greater than the inner ring of template 1 thickness and bearing 1 or the height sum of outer ring; The diameter coupling of the measured hole 21 of bar portion 31 upper part diameter and template 2, promptly the diameter of bar portion 31 upper diameter and template measured hole 20 is a wringing fit; The diameter of bar portion 31 bottoms is less than the diameter of template measured hole 20, and illustrated embodiments is the diameter 0.5～0.6mm of the diameter of the excellent bar of measurement portion 31 bottoms less than template measured hole 20.
The measuring method of the measurement mechanism of the position of mounting hole of large slewing bearing of the present utility model is: elder generation is nested with the locating sleeve 21 of the template 2 of measurement mechanism on the inner ring or outer ring of bearing 1, the inner ring or the cycle surface of template 2 lower surfaces and bearing 1 are attached, and the measured hole 20 on the template 2 is aimed at the inner ring or the mounting hole on the cycle surface 10 of bearing 1; To measure again rod 3 seriatim the measured hole on the template 2 20 insert the mounting hole 10 of bearings 1, can successfully be plugged in measured hole 20 and the mounting hole 10 fully until whole measurement rods 3; Measure in the mounting hole 10 that rod 3 can successfully be plugged on the inner ring of the measured hole 20 of template 2 and bearing 1 or outer ring fully is can be attached to fully with the upper surface of template 2 and exceed to measure pole cap 30 bottom surfaces on the rod 3.
Because the diameter of bar portion 31 bottoms of measurement rod 3 is less than the diameter 0.5～0.6mm of template measured hole 20, if all mounting holes 10 meet the requirements on the inner ring of bearing 1 or the outer ring, measuring rod 3 should just can insert at an easy rate fully, the position degree that promptly shows mounting hole 10 requires at 0.5～0.6mm, and there is not tilt phenomenon in each mounting hole 10 yet.
Template that the measurement mechanism of the position of mounting hole of large slewing bearing of the present utility model is simple and reasonable for structure and measurement rod replace traditional three-coordinates measuring machine, the position of mounting hole that has solved traditional pivoting support bearing need adopt expensive three-coordinates measuring machine to measure, both saved production cost, and it is simple to adopt this measurement mechanism to measure the method for position of mounting hole, has higher measuring accuracy and stability, whether this measuring method can also detect single mounting hole simultaneously and tilt, and has realized the quality of production control to the wind-power electricity generation machine bearing.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
