Description
Technical field
This utility model relates to nondestructive demounting device field, particularly relates to a kind of wind turbine gearbox planet carrier bearing nondestructive demounting device.
Background technology
In the O&M operation process of wind turbine gearbox, passing judgment on after testing and later stage verification experimental verification, the bearing not lost efficacy can recycle after nondestructive demounting. Thus, the nondestructive demounting of gearbox planetary frame bearing is particularly important, and gearbox planetary frame bearing is generally relatively conventional with taper roll bearing, cylinder roller bearing etc.
Summary of the invention
This utility model provides a kind of wind turbine gearbox planet carrier bearing nondestructive demounting device, including top board and screw rod, top board is connected to hook by three screw rods, and three screw rods are uniform in top board horizontal circle circumferential direction, and fasten with nut, hook outside set limited location annulus; Having jack below top board, have lower platen below jack, the diameter of lower platen is less than the diameter of top board.
Described screw rod and nut are M30 screw rod and M30 nut.
Described jack is hydraulic jack.
The beneficial effects of the utility model are: a kind of wind turbine gearbox planet carrier bearing nondestructive demounting device described in the utility model, easy to use, it is possible to realize the nondestructive demounting of gearbox planetary frame front and back bearings smoothly.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of wind turbine gearbox planet carrier bearing nondestructive demounting device described in the utility model;
Fig. 2 is the schematic perspective view of a kind of wind turbine gearbox planet carrier bearing nondestructive demounting device described in the utility model;
Wherein: 1-screw rod; 2-nut; 3-top board; The spacing annulus of 4-; 5-links up with; 6-jack; 7-lower platen; The bearing that 8-is to be removed.
Detailed description of the invention
Detailed narration is will make reference to below with reference to embodiment of the present utility model.
A kind of wind turbine gearbox planet carrier bearing nondestructive demounting device, including top board 3 and screw rod 1, top board 3 is connected to hook 5 by three screw rods 1, and three screw rods 1 are uniform in top board 3 horizontal circle circumferential direction, and fasten with nut 2, set limited location annulus 4 outside hook 5;Having jack 6 below top board 3, have lower platen 7 below jack 6, the diameter of lower platen 7 is less than the diameter of top board 3.
Described screw rod 1 and nut 2 are M30 screw rod and M30 nut.
Described jack 6 is hydraulic jack.
Lower platen 7 is placed on the end face of planet carrier upper bearing (metal) position, and jack 6 is placed on lower platen 7 center position. When jack 6 applies pressure, top board 3 drives screw rod 1 up to move, and screw rod 1 drives hook 5 up to move, and spacing annulus 4 limits three hooks 5 and is subjected to displacement in radial direction, thus three hook 5 band dynamic bearing 8 inner rings up move, bearing 8 is taken apart.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
