Description
Technical field
The utility model relates to a kind of gyratory crusher parts, particularly relates to the eccentric bushing on a kind of gyratory crusher.
Background technology
Gyratory crusher is a kind of mining machinery for broken building stones, and its principle drives the eccentric swing of mantle main shaft group by eccentric stiffener, mantle and fixed bore between to cooperatively interact broken building stones.The eccentric stiffener of existing gyratory crusher specifically comprises bearing block, eccentric bushing and eccentric bush, and eccentric bushing is positioned in bearing block by bearing, and eccentric bush is arranged on eccentric bushing inside; But its weak point is: 1, existing eccentric bushing, by the shape constraining of its outer side surface, causes it not enough by the stability after bearing location and installation, particularly eccentric bushing be easy to axial dipole field, affect the normal use of equipment; 2, existing eccentric bushing, by the shape constraining of its interior sidewall surface, makes eccentric bush can only be fixed on eccentric bushing inside, eccentric bush and eccentric bushing coaxial rotation, and the wearing and tearing thus between eccentric bush and mantle main shaft group are comparatively large, reduce the service life of equipment.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide the eccentric bushing on a kind of gyratory crusher, and this eccentric bushing is convenient to the installation location of himself and eccentric bush, and extends the service life of eccentric bush.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
Eccentric bushing on a kind of gyratory crusher, described eccentric bushing is is integrally connected and composed by bottom the positive heart, in the middle part of bias and eccentric top from bottom to up successively, the diameter of eccentric top outer wall, and the diameter of positive heart bottom outside wall, be all less than the diameter of eccentric middle part outer side surface; Interior sidewall surface bottom the described positive heart is provided with step surface, positive heart bottom inside through hole above step surface and eccentric inside middle portion through hole, and eccentric inside top through hole measure-alike and coaxially arranging, the interior side through hole above step surface is configured for the bushing mounting holes of setting-up eccentricity lining.
The utility model adopts technique scheme, this eccentric bushing has the advantage of following two aspects: 1, eccentric bushing is is integrally connected and composed by bottom the positive heart, in the middle part of bias and eccentric top from bottom to up successively, and the diameter of eccentric middle part outer side surface is all greater than eccentric top outer wall and positive heart bottom outside wall; During installation, bottom the positive heart of eccentric bushing and eccentric top all can be located by bearing, eccentric middle part is between two bearings; So namely, the circumference of the upper and lower both sides of Absorbable organic halogens eccentric bushing is stressed, also can axial restraint eccentric bushing.2, the interior sidewall surface bottom the positive heart of eccentric bushing is provided with step surface, and the interior side through hole above step surface is configured for the bushing mounting holes of setting-up eccentricity lining; During installation, can be arranged in bushing mounting holes by eccentric bush, eccentric bush lower end frame is located on step surface, thus eccentric bush is connected with the Contact of eccentric bushing, non-rigid connection; In use eccentric bush only can produce deflection and can not with eccentric bushing coaxial rotation, reduce the wearing and tearing between eccentric bush and mantle main shaft group, extend the service life of equipment.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is that the utility model is for being arranged on the structural representation on gyratory crusher.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
Eccentric bushing 52 on a kind of gyratory crusher as shown in Figure 1, from bottom to up successively by bottom the positive heart 521, eccentric middle part 522 and eccentric top 523 integrally connect and compose, the eccentric middle part 522 of eccentric bushing 52 and the eccentric top 523 column annular all in width gradual change, the diameter of eccentric middle part 522 outer side surfaces is greater than the diameter of eccentric top 523 outer side surface; Bottom the positive heart of eccentric bushing 52,521 in annular, bottom the positive heart, the diameter of 521 outer side surfaces is less than the diameter of the outer side surface at eccentric middle part 522, bottom the positive heart, the interior sidewall surface of 521 is provided with step surface 521a, side through hole and the eccentric middle part interior side through hole of 522 and the interior side through hole at eccentric top 523 measure-alike and coaxially arranging in 521 bottom the positive heart above step surface 521a, and the interior side through hole above step surface 521a is configured for the bushing mounting holes 58 of setting-up eccentricity lining.
As shown in Figure 2, the eccentric stiffener 5 of gyratory crusher comprises bearing block 51, eccentric bushing 52 and eccentric bush 53, bearing block 51 inner top side is provided with location bearing 54, the top of upper location bearing 54 is provided with top bearing cover 541 and positions, bearing block 51 inside lower end is provided with lower location bearing 55, the below of lower location bearing 55 is provided with end ring 551 and positions, and end ring 551 is fixed on the lower surface of bearing block 51; Bearing block 51 interior sidewall surface between upper location bearing 54 and lower location bearing 55 is provided with bearing spacer ring 56, upper location bearing 54 and lower location bearing 55 location is separated by bearing spacer ring 56.Eccentric bushing 52 by upper location bearing 54 and lower location bearing 55 location and installation in bearing block 51, bottom the positive heart of specifically eccentric bushing, 521 are in lower location bearing 55, eccentric top 523 is in location bearing 54, and eccentric middle part 522 is in bearing spacer ring 56.Described eccentric bush 53 is arranged in bushing mounting holes 58, eccentric bush 53 is cylinder ring body, the inside of eccentric bush 53 is for installing the bottom of mantle main shaft group 3, during equipment work, eccentric bushing 52 is transmitted mechanism and drives, eccentric bushing 52 rotates and drives eccentric bush 53 and the mantle main shaft group 3 of its inside, and finally makes mantle main shaft group 3 do swing campaign.
In sum, this eccentric bushing has the advantage of following two aspects: 1, eccentric bushing is is integrally connected and composed by bottom the positive heart, in the middle part of bias and eccentric top from bottom to up successively, and the diameter of eccentric middle part outer side surface is all greater than eccentric top outer wall and positive heart bottom outside wall; During installation, bottom the positive heart of eccentric bushing and eccentric top all can be located by bearing, eccentric middle part is between two bearings; So namely, the circumference of the upper and lower both sides of Absorbable organic halogens eccentric bushing is stressed, also can axial restraint eccentric bushing.2, the interior sidewall surface bottom the positive heart of eccentric bushing is provided with step surface, and the interior side through hole above step surface is configured for the bushing mounting holes of setting-up eccentricity lining; During installation, can be arranged in bushing mounting holes by eccentric bush, eccentric bush lower end frame is located on step surface, thus eccentric bush is connected with the Contact of eccentric bushing, non-rigid connection; In use eccentric bush only can produce deflection and can not with eccentric bushing coaxial rotation, reduce the wearing and tearing between eccentric bush and mantle main shaft group, extend the service life of equipment.
