Understand for technical characterictic, purpose and effect to utility model have more clearly, contrast the specific embodiment of description of drawings the utility model at present, identical label is represented identical part in each figure.In the accompanying drawing of each embodiment of expression, the identical or structural similarity of identical numeral structure but the identical parts of function.
For making drawing succinct, only schematically shown out the part relevant among each figure with the utility model, they do not represent its practical structures as product.In addition, so that drawing succinctly is convenient to understand, the parts that in some figure, have same structure or function have only schematically illustrated one of them, or have only marked one of them.
In the unloading process of box bearing, at first utilize bearing outer ring and roller disassembly mechanism to remove the roller and the outer ring of bearing simultaneously, utilize the bearing inner race disassembly mechanism to remove the inner ring of bearing again.For clarity sake, hereinafter will be described bearing outer ring and roller disassembly mechanism and bearing inner race disassembly mechanism respectively.
Fig. 1 is used for explaining the exemplary embodiment of the bearing outer ring and the roller disassembly mechanism of bearing disassembling device.As shown in the figure, a pair of gear 40,50 is arranged in the gear-box 38 (only local signal), and gear 40 is installed on the sheathed axle 36, and sheathed axle 36 is arranged on the gear-box 38 through bearing.Bearing generally includes a bearing inner race 34, some rollers 32 and a bearing outer ring 30.In exemplary embodiment shown in Figure 1, bearing outer ring and roller disassembly mechanism 10 comprise a pressing plate group 16, three connecting screw rods 18 (one of them connecting screw rod is not blocked with lifting mechanism 19 by sheathed axle 36 and shows), a top board 17 and a lifting mechanism 19.
In the demolishing process of bearing outer ring and roller; At first use the slit of connecting screw rod 18 via 32 on roller; First pressure head 162 and second pressure head 164 are withheld axial relative two ends at roller 32; And first pressure head 162 is connected with second pressure head 164 is fixed as one, the other end of connecting screw rod 18 is connected fixing with top board 17; The lifting mechanism 19 of between the axle head of sheathed 36 of top board 17 and dismounting bearing institute, packing into then.
After lifting mechanism 19 starts; Lifting top board 17 makes progress; The connecting screw rod 18 that is connected on the top board 17 moves upward thereupon; And then drive pressing plate group 16 and move up, can drive roller 32 and bearing outer ring 30 like this and produce with respect to the moving axially of bearing inner race 34, up to pulling down roller 32 and bearing outer ring 30.After remove the bearing roller of sheathed axle 36 1 ends and outer ring, use the same method again and remove the bearing roller and the outer ring of sheathed axle 36 other ends.
In order to improve the connecting screw rod installation flexibility; Can connecting screw rod be divided into two sections; Wherein one section is used to connect first pressure head and second pressure head, and another section selects the pressing plate group after suitable installation site will connect to be connected with top board, avoids and other constructive interferences of gear-box.
As shown in Figure 1; In the bearing outer ring and roller disassembly mechanism of box bearing provision for disengagement; Two end faces of semicircle pressing plate group 16 can be positioned at the opposite end of being torn open a diameter of bearing, avoid the process middle (center) bearing unbalance stress in dismounting, improve outer ring and roller and dismantle move steady.It will be understood by those skilled in the art that the quantity (like two pressing plate groups and six connecting screw rods) of the connecting screw rod 18 that increases pressing plate group 16 and cooperate with it, make in the demolishing process of bearing roller and inner ring stressed more evenly, move more steady.
In the exemplary embodiment of box bearing provision for disengagement, the lifting mechanism 19 in bearing outer ring and the roller disassembly mechanism can be a jack, or like other lifting mechanism such as crane.
Fig. 2 is used to explain the exemplary embodiment of the bearing inner race disassembly mechanism of bearing disassembling device.As shown in Figure 2, bearing inner race disassembly mechanism 20 comprises the heater 21 of a heating bearing inner race 34.Heater 21 heating bearing inner races 34 make its back of expanding remove from sheathed axle 36.In like manner can remove the bearing inner race of the sheathed axle other end.
As shown in Figure 2, can also comprise a derricking gear 22, a single head double-screw bolt 24 and a gripper shoe 26 in the bearing inner race disassembly mechanism 20.Wherein, One end of derricking gear 22 is connected in an axle head of sheathed axle 36; And derricking gear 22 can drive sheathed axle 36 edges and move with its axial perpendicular direction; The no end of thread 242 of single head double-screw bolt 24 supports another axle head of sheathed axle 36, and the middle part of gripper shoe 26 offers gathering sill 262, and the end of thread 244 of single head double-screw bolt 24 passes gathering sill 262; And can move in gathering sill 262 with the axially perpendicular direction of single head double-screw bolt 24 on the edge, and the end of thread 244 of single head double-screw bolt 24 can be screwed on the gear-box 38.
As shown in Figure 2, derricking gear 22 supports sheathed axle 36 with gripper shoe 26, when derricking gear 26 can drive the direction shown in sheathed axle 36 arrows and moves; Sheathed axle 36 can steadily move at gathering sill 262, moves to the position shown in the figure, and the gear of installing on the sheathed axle 36 40 breaks away from the engagement with gear 50; Make formation is enough between overcoat 34 and the gear-box 38 space so that heater to be set, like this in the process of heating bearing inner race 34, sheathed axle 36 can rotate simultaneously; To regulate cog 40 position of sheathed axle 36; With the contact force of sheathed axle 36 with gripper shoe 26, can avoid bearing inner race 34 hot-spots, also made things convenient for the dismounting of bearing inner race 34.
In a kind of exemplary embodiment of box bearing provision for disengagement, be connected by bolt between gripper shoe 26 and the gear-box 38, to make things convenient for the installation of gripper shoe 26.
In the another kind of exemplary embodiment of box bearing provision for disengagement, derricking gear 22 is a hanging bolt, with the installation that makes things convenient for derricking gear 22 be connected.
Use the bearing disassembling device of gear-box, can reduce bearing is born when removing axial force and dismounting difficulty, avoided bearing surface to be damaged, improved the utilizability behind the bearing removal.
