Technical problem to be solved in the utility model is: the provision for disengagement that is used for the universal mill roll bearing that a kind of simple in structure, disassembling section is convenient, removal efficiency is high is provided.
The technical scheme that solves the problems of the technologies described above is: be used for the provision for disengagement of universal mill roll bearing, comprise pressure-bearing round platform, force transferring structure and actuating unit; Paste mutually the lower surface of the described bearing demolition that the upper surface of described pressure-bearing round platform is interior with being installed in described bearing demolition seat; One end of described force transferring structure is connected with described pressure-bearing round platform; One end of described actuating unit is supported on the end face of described bearing demolition seat, this end face and described bearing demolition upper surface homonymy, and the other end of described actuating unit and the other end of described force transferring structure hold out against.
Further be, described force transferring structure be one by base-plate be installed in the frame supporter that the door type force transmission rack on this base-plate constitutes, the lower surface of described pressure-bearing round platform is supported on the described base-plate, and the other end of described actuating unit holds out against on the crossbeam of described door type force transmission rack.
Further be, described force transferring structure is the drawing support plate of a T font structure, the length of the horizontal sides of described T font structure drawing support plate is greater than the race diameter of described bearing demolition, the inner ring that the free end of the vertical edges of described T font structure drawing support plate passes described bearing demolition is connected with described pressure-bearing round platform, and the other end of described actuating unit holds out against on the lower edge of described drawing support plate horizontal sides.
Further be that the contacted end face of described pressure-bearing round platform and described bearing demolition is provided with the location dome circle of external diameter less than described bearing demolition internal diameter.
Further be that described location dome circle is provided with guide.
Further be that described actuating unit is a jack.
The beneficial effects of the utility model are: by on an end face of described bearing demolition a pressure-bearing round platform being set; The upper surface of described pressure-bearing round platform is pasted mutually with the lower surface of described bearing demolition, thereby will pass to bearing demolition by the external force that described bearing demolition is withdrawed from that force transferring structure applies from inner hole of bearing seat by actuating unit, in order to offset the dismounting resistance between bearing outer ring and the inner hole of bearing seat, and then reach the more convenient purpose that described bearing demolition is dismantled from inner hole of bearing seat, this apparatus structure is simple, disassembling section is convenient, the removal efficiency height of dismounting roll bearing from roll chock, avoided simultaneously forcing dismounting, bigger application value has been arranged the damage that bearing causes.

Fig. 2 is the A-A cutaway view of the utility model Fig. 1;
Fig. 3 is used for the another kind of structural representation of roll bearing provision for disengagement for the utility model.
Be labeled as among the figure: pressure-bearing round platform 1, location dome platform 11, guide 12, drawing support plate 2, bearing block 3, bearing 4, actuating unit 5, base-plate 6, door type pass frame 7.
The specific embodiment
Be the provision for disengagement that is used for the universal mill roll bearing that a kind of simple in structure, disassembling section is convenient, removal efficiency is high that the utility model provides as shown in Figure 1 and Figure 2.Described provision for disengagement comprises pressure-bearing round platform 1, force transferring structure and actuating unit 5; Paste mutually with the lower surface of described bearing demolition 4 in being installed in described bearing demolition seat 3 upper surface of described pressure-bearing round platform 1; One end of described force transferring structure is connected with described pressure-bearing round platform 1; One end of described actuating unit 5 is supported on the end face of described bearing demolition seat 3, this end face and described bearing demolition 4 upper surface homonymies, and the other end of described actuating unit 5 and the other end of described force transferring structure hold out against.After adopting the provision for disengagement of described structure, when my position need split out bearing 4 from bearing block 3, only need starting actuating unit 5 to apply the external force that described bearing demolition 4 is withdrawed from from bearing block 3 endoporus by force transferring structure, in order to offset the dismounting resistance between bearing demolition 4 outer rings and bearing block 3 endoporus, just can very easily described bearing demolition 4 be split out from bearing block 3 endoporus.This apparatus structure is simple, disassembling section is convenient, from roll chock the removal efficiency height of dismounting roll bearing, avoided simultaneously forcing dismounting to the damage that bearing causes, bigger application value is arranged.
Described force transferring structure be one by base-plate 6 be installed in the frame supporter that the door type force transmission rack 7 on this base-plate 6 constitutes, the lower surface of described pressure-bearing round platform 1 is supported on the described base-plate 6, and the other end of described actuating unit 5 holds out against on the crossbeam of described door type force transmission rack 7.The characteristics of this force transferring structure are: the part that constitutes described force transferring structure is more, make complicated, but described force transferring structure in use stability under loading is reliable, it is bigger to be particularly suited for volume, need apply in the bearing that big external force could dismantle to use.The utility model also provides the force transferring structure of another structure, be that described force transferring structure is the drawing support plate 2 of a T font structure, the length of the horizontal sides of described T font structure drawing support plate 2 is greater than the race diameter of described bearing demolition 4, the inner ring that the free end of the vertical edges of described T font structure drawing support plate 2 passes described bearing demolition 4 is connected with described pressure-bearing round platform 1, and the other end of described actuating unit 5 holds out against the lower edge in described drawing support plate 2 horizontal sides.The characteristics of this force transferring structure are: the part that constitutes described force transferring structure is few, makes simply, but in use stability under loading is relatively poor, and it is less mainly to be suitable for the body kind, uses in the less bearing arrangement of the dismounting external force that need apply.
Generally speaking, the weight that bearing demolition 4 adds top chock 3 is bigger, and when dismounting pressure-bearing round platform 1 very crucial with the mated condition of bearing demolition 4, in order to make pressure-bearing round platform 1 and cooperating of bearing demolition 4 reach optimum efficiency, described pressure-bearing round platform 1 is provided with the location dome circle 11 of external diameter less than described bearing demolition 4 internal diameters with described bearing demolition 4 contacted end faces; Described location dome circle 11 is provided with guide 12.So just, can very easily bearing demolition 4 be lifted with pressure-bearing round platform 1 and cooperate the raising removal efficiency.
Described actuating unit 5 can be a hydraulic cylinder, but the purchase cost height of hydraulic cylinder, and structure is complicated, uses inconvenience, actuating unit 5 described in the utility model for this reason is a jack, can be hydraulic jack, also can be mechanism's tool jack.
