The utility model discloses simple structure, the easy expense of preparation are hanged down, adopt threaded connection, and loading and unloading are stored conveniently, and occupation space is little, use easy operation, and the security is good, hydraulic drive, labour saving and time saving has reduced the intensity of labour that the bearing was dismantled, also can not harm the bearing, has improved the maintainability and the life of bearing, has reduced the production run cost of enterprise, and economic nature is good.

Description

A kind of planet wheel bearing disassembling fixture
Technical field
The utility model relates to a kind of extracting tool, is specifically related to a kind of planet wheel bearing disassembling fixture for planetary wheel of wind turbine gearbox bearing.
Background technology
As everyone knows at wind turbine gearbox transmission field, especially when planetary wheeling assembly breaks down, need analyzing failure cause, dismounting planet wheel bearing.Because planet wheel spindle bearing outer-ring and planetary gear endoporus are that interference is connected, be that assembling or dismounting planet wheel bearing are all very difficult.Current dismounting planet wheel bearing adopts hydraulic press to force pressure to split out mostly, tears open in process, due to pressurized bearing enclose end face unbalance stress, usually cause planetary gear endoporus to pull in pressure, makes planetary gear cannot continue to use.When having two row bearings in planetary gear and axial opposed direction is located all, then cannot tear open by hydraulic press pressure, as forced pressure to be torn open, must be that destructive pressure is torn open, this pressure be torn open also without saying in all senses.
Summary of the invention
It is simple, easy to operate that the purpose of this utility model is to provide a kind of structure, can not damage again the planet wheel bearing disassembling fixture of planetary gear during dismounting.
Planetary gear disassembling fixture of the present utility model, comprise hydraulic drive mechanism and bearing pushing mechanism, it is characterized in that: described hydraulic drive mechanism is made up of gripper shoe and hydraulic cylinder, the center of gripper shoe is provided with the screwed hole of connecting fluid cylinder pressure, and hydraulic cylinder is threaded with gripper shoe; Described bearing pushing mechanism is made up of the sleeve of upper plate, base plate and connection upper plate and base plate, and upper plate, base plate are connected by screw with sleeve; The lower end of described sleeve is provided with annular flange, and annular flange is connected with bush whorl; Described upper plate and base plate are provided with central through hole; Described gripper shoe is connected by connecting screw rod with annular flange.
In order to better realize above-mentioned purpose:
Described upper plate, base plate and sleeve have identical external diameter.
Described annular flange is also provided with and adds large circle, add large circle and be connected by screw with annular flange.
The utility model structure is simple, it is low to make easy expense, and employing is threaded, and handling store convenient, and take up room little, use simple to operate, security is good; Hydraulic-driven, time saving and energy saving, reduce the labour intensity of bearing removal, also can not damage bearing, improve maintainability and the service life of bearing, reduce the operating cost of enterprise, good economy performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, gripper shoe, 2, double threaded screw, 3, sleeve, 4, add large circle, 5, base plate, 6, upper plate, 7, hydraulic cylinder, 8, annular flange.
Detailed description of the invention
Planetary gear disassembling fixture of the present utility model, is made up of hydraulic drive mechanism and bearing pushing mechanism.Hydraulic drive mechanism is made up of gripper shoe 1 and hydraulic cylinder 7.The center of gripper shoe 1 is provided with the screwed hole of connecting fluid cylinder pressure 7, and hydraulic cylinder 7 is threaded with gripper shoe 1.Bearing pushing mechanism is by upper plate 6, base plate 5 and be connected upper plate 6 and form with the sleeve 3 of base plate 5, and upper plate, base plate and sleeve have identical external diameter, upper plate 6, base plate 5 with sleeve 3 by screws tighten.The lower end of sleeve 3 is provided with annular flange 8, and annular flange 8 is threaded with sleeve 3, and annular flange 8 is provided with and adds large circle 4, adds large circle 4 and is connected by screw with annular flange 8.Upper plate 6 and base plate 5 are provided with central through hole.Hydraulic cylinder 7 is threaded with gripper shoe 1, and the axle of hydraulic cylinder 7 passes the centre bore of upper plate 6 and base plate 5, and gripper shoe 1 is connected by double threaded screw 2 with annular flange 8, hydraulic drive mechanism and bearing pushing mechanism is connected as a single entity.
During use, rotate double threaded screw 2, the adjustment position of upper plate 6 on hydraulic cylinder 7 axial direction, end face and the planet wheel bearing Internal and external cycle end face of base plate 5 are fitted.Under the effect of the hydraulic coupling of hydraulic cylinder 7, the responsive to axial force upwards pushed away by base plate 5 pairs of planet wheel bearings, thus planet wheel bearing is ejected come.
