The specific embodiment
The utility model provides a kind of positioner, is applicable to assembling wind-powered electricity generation gear-box, or has other products of similar structures.
The structural representation of the positioner that Fig. 2 provides for the utility model embodiment one.The utility model embodiment one provides a kind of positioner, comprising substrate 5, positioning core axle 6 and supporting seat 7; Positioning core axle 6 is fixedly connected with substrate 5, and positioning core axle 6 is used to wear the fixedly endoporus of wind-powered electricity generation gearbox input shaft; The quantity of supporting seat 7 is two, disperses to be fixed on the substrate 5, is used to support two toggles of wind-powered electricity generation gear-box.
It is understandable that positioning core axle is used to wear the fixedly endoporus of wind-powered electricity generation gearbox input shaft, so the size of positioning core axle should be complementary with the size of endoporus, so-called coupling is meant that the gap between positioning core axle and the endoporus is 0.2mm-1mm.The position of supporting seat on substrate also is by two toggle determining positions of wind-powered electricity generation gear-box.Through hole can also be offered in the middle part of positioning core axle, with loss of weight.
The positioner that the utility model embodiment one provides; The endoporus of going forward to offer on the casing with the wind-powered electricity generation gear-box is as main locating surface; As the acting surface that supports the whole wind electrical gearbox, the slip that occurs in the assembling process because of the wind-powered electricity generation gear-box, the mobile rigging error that produces have been prevented with toggle effectively.The positioner that the utility model embodiment one provides has realized that not only the strong fix of wind-powered electricity generation gear-box supports, and has protected the bearing of input shaft of wind-powered electricity generation gear-box, has also improved the precision of wind-powered electricity generation gear-box assembling and the security of assembling work.
The structural representation of the positioner that Fig. 3 provides for the utility model embodiment two.The utility model embodiment two is on the technical scheme basis of the utility model embodiment one, and further, each supporting seat 7 top also is equipped with gland 8, and gland 8 is provided with groove 81, and groove 81 is used for ccontaining toggle.
Gland can circumferentially coat toggle, and is spacing so that the top of toggle and side are carried out, and through the free degree of further restriction toggle, realizes the purpose of the limiting gear case free degree.Gland is set to make to the location of toggle more accurately and reliably.
In the practical application, can preceding casing be placed on the supporting seat and afterwards gland be installed again, so alternatively: gland 8 is connected with supporting seat 7 bolts.Bolt connects simple and reliable, and is convenient to dismounting.
The positioner that the utility model embodiment two provides further defines the free degree of wind-powered electricity generation gear-box toggle, and location and the effect that supports are more reliable, and the security of use is also higher.
Fig. 4 a is the sketch map of the positioner that provides of the utility model embodiment three; Fig. 4 b looks sketch map for the master of Fig. 4 a; Fig. 4 c is the schematic top plan view of Fig. 4 a; Fig. 4 d looks sketch map for the left side of Fig. 4 a, and the positioner that Fig. 4 e provides for use the utility model embodiment three is located the sketch map of the preceding casing of wind-powered electricity generation gear-box.The utility model embodiment three preferably, also is equipped with support column 9 on the substrate 5 on the technical scheme basis of the foregoing description; Support column comprises foundation 91 and threaded rod 92, and foundation 91 is fixed on the substrate 5, and foundation 91 middle parts vertically offer screwed hole 93, is used for cooperating with threaded rod 92.Wind-powered electricity generation gear-box total quality is very big, support column is set can alleviates the load of bearing on the supporting seat.
Support column is set to above-mentioned Height Adjustable form, can reduce the requirement on machining accuracy of parts, reduces manufacturing cost.Need to prove, also can select for use other Height Adjustable devices to replace above-mentioned form.
The size of threaded rod is limited, for the ease of the height of adjustable support post, and reduces the stress of threaded rod to preceding casing, and preferably, threaded rod 92 is set with top board 94 away from an end of substrate 5, top board 94 circumferentially evenly be fixed with several swingles 95.Swingle is set, can be so that rotate threaded rod.
Consider the weight of wind-powered electricity generation gear-box, several support columns can be set to strengthen support effect: the quantity of support column 9 is several, disperses to be installed on the substrate 5 more.Present embodiment is the signal that example is carried out so that three support columns to be set, but is not limited in this.
Positioner possibly assembled stand with movable type and be used in practical application, so the substrate of positioner should be assembled the work top and the industrial castor of stand with avoiding movable type, any interference can not occur.In the present embodiment, substrate is set to octagon, has not only alleviated the weight of substrate, can also guarantee positioner and good the cooperating of portable assembling stand, to accomplish the assembling of wind-powered electricity generation gear-box.
The positioner that the utility model embodiment three provides; Supporting seat and gland mating reaction; Can carry out reliable and stable support to whole gear-box effectively; And realized safe and reliable the fixing of gear-box prevented that effectively the generation of situation such as rotation, upset from appearring in gear-box in assembling process.The volume and weight of considering gear-box is all big, and supporting seat is little to the Area of bearing of toggle, and the stress that toggle receives is big, on positioner, has designed support column with the supplemental support as preceding casing.In addition, support column can freely be adjusted height, after the toggle of preceding casing is placed on the supporting seat; Support column has upwards been revolved the height of casing to the wind-powered electricity generation gear-box; Can realize assist location to preceding casing, increased the location area of gear-box, make and locate firm, stable more.The positioner that the utility model embodiment three provides has effectively been protected the parts such as fore bearing on the wind-powered electricity generation gearbox input shaft, has improved the packaging efficiency and the assembly precision of wind-powered electricity generation gear-box, has prolonged the service life of wind-powered electricity generation gear-box.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
