Detailed description of the invention
Fig. 2 is the instrumentation plan of wind turbine gearbox flexible pin shaft conical ring measurement leveling tool of the present invention, and Fig. 3 is wind turbine gearbox flexible pin shaft conical ring measurement leveling tool structural representation of the present invention, and Fig. 4 is the sectional view of the adjusting rod in Fig. 3.In conjunction with Fig. 2 to Fig. 4, the wind turbine gearbox flexible pin shaft conical ring measurement leveling tool that the present embodiment provides, including: horizontally disposed pressing plate 201, pressing plate 201 center offers the installation through hole 202 for wearing planet bearing pin；Being fixedly installed the vertically extending adjusting rod of at least three 203 around through hole 202 respectively on pressing plate 201 and installing, at least three adjusting rod 203 is all equal to the distance installing through hole 202 center, and the distance of adjacent two adjusting rods 203 is equal；The end of adjusting rod 203 is provided with the hold-down head 205 for supporting on the end face to be grinding 210 of conical ring 213, and hold-down head 205 can move along adjusting rod 203 towards pressing plate 201；Being arranged with an elastic component 204 on adjusting rod 203, the two ends of elastic component 204 are supported respectively on pressing plate 201 and hold-down head 205.
Specifically, this pressing plate 201 offering installation through hole 202, the size installing the aperture of through hole 202 can be that the diameter than the pin 212a in Assembly of pin 212 is bigger, and wherein, Assembly of pin 212 is made up of pin 212a and axle 212b；The adjusting rod 203 that can wear at least three, vertically extend around through hole 202 is being installed, and at least three adjusting rod 203 lays respectively at each apex of same regular polygon, adjusting rod 203 is arranged with elastic component 204, the end of adjusting rod 203 is provided with hold-down head 205, and hold-down head 205 can move along adjusting rod 203 towards pressing plate 201.
Preferably, this pressing plate 201 can be circular slab, offers groove 207 respectively at the edge of pressing plate 201 and between two adjacent adjusting rods 203.The shape of pressing plate 201 is not limited by the present embodiment.
Preferably, the sum of adjusting rod 203 and hold-down head 205 all can respectively four, and certainly, the sum of adjusting rod 203 and hold-down head 205 is it can also be provided that three or five, and the present embodiment is not limited thereto.
Further, pressing plate 201 can being offered four tapped through holes, the top of four adjusting rods 203 is bolted in four tapped through holes respectively and runs through pressing plate 201, and is fastened on pressing plate 201 by adjusting rod 203 by the nut on the top of the adjusting rod 203 that is spirally connected.
Specifically, the distance between adjacent two tapped through holes is equal, thus four adjusting rods 203 can be distributed uniformly and be fixed on pressing plate 201, and by being spirally connected the locking nut 206 on adjusting rod 203 top, makes what adjusting rod 203 more fastened to be fixed on pressing plate 201.The present embodiment is not limiting as the fixing connected mode between adjusting rod 203 and pressing plate 201, in other embodiments, for instance, it is possible to it is by interference fit, adjusting rod 203 and pressing plate 201 are assembled together.
Preferably, above-mentioned elastic component 204 can be compression spring.After locking due to locking nut 206, pressing plate 201 can be pressed downward against, make pressing plate 201 and convex annular appear laminating closely, and then make compression spring can be in compressive state at the beginning, but be not compressed to compression limit.One end owing to compressing spring withstands on pressing plate 201, and the other end withstands on hold-down head 205, when compressing spring and being in compressive state, it is possible to 205 1 downward power of hold-down head, so that hold-down head 205 can be supported on the end face to be grinding 210 of conical ring 213.
The wind turbine gearbox flexible pin shaft conical ring 213 measurement leveling tool that the present embodiment provides is when carrying out leveling to conical ring 213, first conical ring 213 set is set on Assembly of pin 212, then wind turbine gearbox flexible pin shaft conical ring 213 measurement leveling tool set is set on Assembly of pin 212, the hold-down head 205 of adjusting rod 203 end can be supported on the end face to be grinding 210 of conical ring 213, owing to adjusting rod 203 is uniformly distributed, and elastic component 204 meeting being set on adjusting rod 203 apply a downward power to hold-down head 205, thus conical ring 213 can be made to be substantially at level, by reading the registration of the dial gauge 208 being fixed in two grooves 207 relative on pressing plate 201 edge, can determine whether whether conical ring 213 is in level, if conical ring 213 is not in level, need conical ring 213 is finely tuned, by higher while the instrument of use clouting gently, read the registration of relative two piece dial gauge 208 again, until conical ring 213 is in level.
From the foregoing, the wind turbine gearbox flexible pin shaft conical ring measurement leveling tool that the present embodiment provides, by the setting of hold-down head and elastic component on adjusting rod and adjusting rod, ensure that the accurate, reliable of measurement result, and simple in construction, it is easy to operation, improves measurement work efficiency.
Further, above-mentioned respective slot 207 place is additionally provided with for measuring groove 207 position dial gauge 208 to the vertical dimension of the end face to be grinding 210 of conical ring 213.Alternatively, dial gauge 208 is fixed in the groove 207 on the edge of pressing plate 201 by connecting fixture block 209.
Specifically, dial gauge 208 is used for facilitating staff whether to observe conical ring to be measured 213 already at level.Staff is before measuring conical ring 213, by reading the registration of relative two piece dial gauge 208 and calculating the difference between the two registration, if this difference is less than or equal to 0.05mm, then illustrates that conical ring 213 is horizontal, and meets design requirement；If this difference is more than 0.05mm, illustrate that conical ring 213 is not on horizontal level, for meeting design requirement, it is necessary to again finely tune, so that conical ring 213 is in level.In the present embodiment, if the curtailment measuring bar of dial gauge 208 is so that measuring the end face to be grinding 210 of head contact conical ring 213, four contour posts 211 can also be placed between head and the end face to be grinding 210 of conical ring 213 measuring of dial gauge 208, the head of measuring making dial gauge 208 is against the upper surface of contour post 211, thus shortening the end face to be grinding 210 of conical ring 213 and the distance measured between head of dial gauge 208.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein some or all of technical characteristic is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
