Description
Technical field
The utility model relates to a kind of securing means, is specifically related to a kind of securing means for wind power generating set.
Background technique
Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 109MW, and wherein available wind energy is 2 × 107MW, than the water energy total amount that the earth can develop also large 10 times.Wind Energy In China reserves are very large, it is wide to distribute, and only the wind energy content of land just has an appointment 2.53 hundred million kilowatts.
The Wind Power Generation Industry of China has also stepped into high speed development track.2014, national Wind Power Generation Industry continued to keep the strong growth impetus, annual wind-powered electricity generation adding new capacity 1,981 ten thousand kilowatts, adding new capacity records high, accumulative grid-connected electric motor power reaches 9,637 ten thousand kilowatts, accounts for 7% of whole capacity of installed generator, accounts for 27% of the installation of global wind-powered electricity generation.Wind-powered electricity generation electricity volume 1,534 hundred million kilowatt hour in 2014, accounts for 2.78% of whole generated energy.Wind power equipment manufacturing capacity also strengthen continuously, technical merit significantly promotes, and the newly-increased wind power equipment lifting in whole nation capacity 2,335 ten thousand kilowatts, increase by 45% on a year-on-year basis, national wind power equipment adds up lifting capacity and reaches 1.15 hundred million kilowatts, increases by 25.5% on a year-on-year basis.
The equipment of wind power generating set seems simple, actually bulky, technical sophistication, and making and installation difficulty is very large.Existing wind driven generation set main shaft bearing after mounting more uses a kind of tightening nut, limits bearing change in location by the pretightening force of screw-thread fit.The problem of securing means dismounting difficulty, complex procedures when motor bearings being axially fastened in order to solve, the patent No. be 201120424110.2 Chinese utility model patent propose a kind of Simple demountable self-locking-type locknut, comprise nut body and the screw running through nut body, the outer side surface of nut body has the distortion gap with screw axes normal, and the end face of nut body has the backing-up screw mounting hole running through distortion gap.Tighten backing-up screw, the screw thread in the screw thread of screw and rotating shaft is extruded mutually produce to rub, locking object can be reached.
But technique scheme is only axially extruding the screw thread nut body and the screw thread in rotating shaft from rotating shaft, produces frictional force.And be not very large at the pressure of its radial direction, corresponding radial frictional force is also very little, is only difficult to effectively lock securing means by axial extruding in a lot of situation.In addition, when the diameter of bolt of Wind turbines is larger, nut seems heavy, and carrying fastened tools is also very inconvenience.
Therefore, how the securing means of more effective wind power generating set is those skilled in the art's problems urgently to be resolved hurrily.
Model utility content
Main purpose of the present utility model is to provide the purpose of this utility model to be to provide one can carry out axis and radial locking to Wind turbines rotating shaft simultaneously, and easy installation and removal, operation is simply for the securing means of wind power generating set; Meanwhile, this securing means can also carry out axially and radial locking the larger bolt of other volumes or screw.
For reaching above object, the technical solution adopted in the utility model is: a kind of securing means for wind power generating set, comprise the main body nut be threaded with Wind turbines parts, it is characterized in that: inside described main body nut, offer the axial deformation groove parallel with described main body nut end face, described main body nut one end face to offer through described axial deformation groove and perpendicular to the axial threaded hole of described axial deformation groove, described main body nut one end face also offers vertical described main body nut end face and is parallel to the radial deformation groove in described main body nut inner arc face, offer outside described main body nut and extend to described radial deformation groove and the radial screw bore being parallel to described main body nut end face, axial locking bolt is installed in described axial threaded hole, in described radial screw bore, radial lock bolt is installed, described axial locking bolt can pass described axial deformation groove, and the length of described axial locking bolt is less than the length of described axial threaded hole, described radial lock bolt can extend to described radial deformation groove inner side surface, and the length of described radial lock bolt is greater than the length of described radial screw bore.This structure can ensure, when tightening axial locking bolt, make main body nut end face produce small distortion, the screw thread on the screw thread on causative subject nut and Wind turbines parts produces frictional force axially mutually extruding, reach axial locking, prevent the object loosened; When tightening radial lock bolt, make main body nut inner side surface produces small distortion, the screw thread on the screw thread on causative subject nut and Wind turbines parts extrudes generation frictional force mutually in radial direction, reaches radial locking, prevents the object loosened.
As preferably, described axial deformation groove is four, and is uniformly distributed along described main body nut circumference direction; Corresponding described axial threaded hole is four, and all through the neutral position of four described axial deformation grooves.Four for comparatively reasonably to arrange.
As a step is preferred again, described radial deformation groove is four, and is uniformly distributed along described main body nut circumference direction; Corresponding described radial screw bore is four, and all through the neutral position of four described radial deformation grooves.Same four for comparatively reasonably to arrange.
As preferred further, four described axial deformation grooves and four described radial deformation groove intervals are arranged, and described axial deformation groove and described radial deformation groove are without common factor.Interval arranges and makes between the two without the intensity that ensure that securing means of occuring simultaneously, and the interaction between the two avoided produces not expected consequence.
Compared with prior art, the utility model has the advantage of: by coordinating of axial locking bolt and axial deformation groove and axial threaded hole, and the coordinating of radial lock bolt and radial deformation groove and radial screw bore, reaching can simultaneously to Wind turbines rotating shaft and the larger bolt of other volumes or screw carries out axially and the object of radial locking, and this securing means easy installation and removal, operation are simple.
