Accompanying drawing explanation
Fig. 1 is the perspective view of bearing disassembling device described in the utility model.
Detailed description of the invention
Below by specific embodiments and the drawings, the utility model is described in further detail.
Bearing disassembling device, as shown in Figure 1, comprise first, second dismounting frame 1,2, be characterized in: first, second dismounting frame 1,2 is evenly provided with several first open-work 11 and several second open-work 21 respectively, first, second open-work 11,21 is mutually corresponding, the front end of first, second dismounting frame 1,2 is also respectively arranged with the first boss 12 and the second boss 22 taking off inside bearing 71, the two ends of position-limited rack 3 are each passed through the first open-work 11 and the second open-work 21 on first, second dismounting frame 1,2, and position-limited rack 3 and driving mechanism are fixedly connected; When bearing disassembling device works, first, second dismounting frame 1,2 mechanism that is locked is locked at the both sides of bearing 7, and first, second boss 12,22 on it to take off inside bearing 71, driving mechanism drives first, second dismounting frame 1,2 to extract bearing 7 to the disassembly direction motion of bearing 7 by position-limited rack 3.In the present embodiment, by regulating the distance between first, second dismounting frame 1,2, can dismantle the bearing 7 of different size; Equally distributed open-work on first, second dismounting frame 1,2, can make position-limited rack 3 position that front and back are different between first, second dismounting frame 1,2, to dismantle the bearing 7 of different fitting depth.In the present embodiment, described retaining mechanism comprises the U-shaped support 5, the pin 8 that straddle on first, second dismounting frame 1,2, first, second side arm 51,52 of U-shaped support 5 is evenly provided with respectively several first pin-and-hole 511 and several second pin-and-hole 521, and first, second pin-and-hole 511, about 521 is mutually corresponding, U-shaped support 5 is locked first, second dismounting frame 1,2 through first, second pin-and-hole 511,521 mutually corresponding on it by pin 8; U-shaped support 5 and pin 8 is used to lock, enormously simplify retaining mechanism on the one hand, pin 8 inserts the pin-and-hole of diverse location on U-shaped support 5 on the other hand, can regulate the distance between pin 8 to U-shaped support linking arm 53, first, second distance dismantled between frame 1,2 that so just can adapt to cause to dismantle different size bearing 7 changes.Further, aforementioned locking mechanism also comprises trimming bolt 54, and trimming bolt 54 is by the screwed hole 541 that screws on U-shaped support linking arm 53 and withstand the first dismounting frame 1 or the second dismounting frame 2 is finely tuned the elasticity between first, second dismounting frame 1,2; Use trimming bolt 54 pairs of elasticities to finely tune, the situation of the not tight reality existed because the pin-and-hole only inserting diverse location on U-shaped support 5 by pin 8 carries out locking can be reduced.
In the present embodiment, the upper surface of first, second boss 12,22 described is respectively arranged with the arc-shaped surface concaved.Such setting, can increase the contact area between first, second boss 12,22 and bearing 7, makes bearing 7 be more prone to be removed by taking off.
In the present embodiment, described driving mechanism is oil cylinder 4, the cylinder body screw thread of position-limited rack 3 and oil cylinder 4 is fixed, when bearing disassembling device works, stretched out forward by the piston rod of oil cylinder 4 and withstand the end face of axle 6 installing bearing 7 side, make the cylinder body of oil cylinder 4 drive position-limited rack 3, retaining mechanism and first, second dismounting frame 1,2 to move to the disassembly direction of bearing 7, finally pull down bearing 7; Oil cylinder 4 can be driven by hand oil pump 9.Oil cylinder 4 is conventional driving mechanisms, is easy to buy; The cylinder body of employing oil cylinder 4 is threaded with position-limited rack 3 and oil cylinder 4 piston rod stretches out forward and withstands the end face of the axle 6 installing bearing 7 side, oil cylinder 4 can be made not need to fix with ground, first, second dismounting frame 1,2 just can be allowed to move to the disassembly direction of bearing 7.
The operation principle of bearing disassembling device described in the present embodiment is: as shown in Figure 1, first first, second dismounting frame 1, 2 both sides being placed on bearing 7, then allow first on it, second boss 12, 22 to take off inside bearing 71, then with straddling first, second stripping attachment 1, U-shaped support 5 on 2 and pin 8 are to first, second dismounting frame 1, 2 tentatively lock, then screw in the screwed hole 541 on U-shaped support linking arm 53 by trimming bolt 54 and withstand the first dismounting frame 1 and come first, second dismounting frame 1, elasticity between 2 is finely tuned, and makes it reach suitable elasticity, then the two ends of position-limited rack 3 is passed first, second open-work 11, 21 and be placed in first, second dismounting frame 1, the centre of 2, the cylinder body of oil cylinder 4 and position-limited rack 3 screw thread are fixed, manually oil cylinder 4 fuel feeding given by oil pump 9 again, oil cylinder 4 piston rod stretched out and withstands the end face of the axle 6 installing bearing 7 side, along with oil cylinder 4 piston rod continue stretch out, the cylinder body of oil cylinder 4 drives position-limited rack 3, retaining mechanism and first, second dismounting frame 1, 2 move to the disassembly direction of bearing 7, finally pull down bearing 7.
The beneficial effects of the utility model are: use bearing disassembling device described in the utility model, while not damaging axle and bearing, bearing can be disassembled quickly and easily from axle, decrease expense and the time of maintenance.
