Abstract
The utility model discloses a guide wheel, thrust wheel and bearing chain wheel axle bed life's structure can prolong, including axle, axle bed, wheel body, turn -ups axle sleeve and fixed mounting at the baffle of turn -ups axle sleeve with axle bed faying face department, spool install in the axle bed, the wheel body is installed epaxial, turn -ups bushing installation between wheel body, axle and axle bed, interference fit between wheel body and the turn -ups axle sleeve. The utility model discloses an add the baffle between turn -ups axle sleeve and axle bed for turn -ups axle sleeve and axle bed contactless, when the wheel body rotated, the friction produced at the faying face of turn -ups axle sleeve with the baffle, makes axle bed and wheel body avoid friction and wear, has improved the life of axle bed with the wheel body. Treat that the baffle weares and teares after the certain degree, directly change the baffle can, need not to change the axle bed, reduced the cost of renewal part.
Description
Technical field
This utility model is related to a kind of structure that can extend guide wheel, thrust wheel and support sprocket wheel axle bed service life, category
In technical field of engineering machinery.
Background technology
In large-scale and ultra-large type engineering machinery guide wheel, thrust wheel and support sprocket wheel, existing structural representation such as Fig. 3
It is shown, wherein, the effect of axle bed 2 is that, for fixing whole wheel body 5, when wheel body 5 is rotated, axle bed 2 is fixed.So
Relative motion will be produced at wheel body 5 and the faying face of axle bed 2, so as to produce friction, abrasion is caused.If in 5 faying face of wheel body
Place press-fits flanger bearing bush 4, and wheel body 5 can be protected not frayed at faying face, the flange face of the flanger bearing bush 4 that only weares and teares, and works as mill
When damaging serious, flanger bearing bush 4 is directly changed.But in actual use, axle bed 2 is not accordingly protected at faying face
Shield, abrasion can be relatively serious, and the expense for changing whole axle bed completely is higher, can so bring some unnecessary losses.
The content of the invention
For above-mentioned prior art exist problem, this utility model provide one kind can extend guide wheel, thrust wheel and
The structure of support sprocket wheel axle bed service life, can reduce the abrasion at axle bed faying face, reduce the cost of renewal part.
To achieve these goals, one kind that this utility model is adopted can extend guide wheel, thrust wheel and support sprocket shaft
The structure of seat service life, including axle, axle bed, wheel body and flanger bearing bush, axle are arranged in axle bed, and wheel body is mounted on an axle,
Flanger bearing bush is arranged between wheel body, axle and axle bed, and interference fit between wheel body and flanger bearing bush is also turned over including being fixedly mounted on
Dividing plate at side axle sleeve and axle bed faying face, when wheeling thereof, flanger bearing bush is also rotated together, and dividing plate and axle bed are fixed not
It is dynamic, relative motion can be produced at flanger bearing bush and membrane engaging surface, friction is produced, rub suffered by axle bed so as to be reduced.
Preferably, the dividing plate is arranged on axle bed by alignment pin.
Preferably, the material of the dividing plate is high-abrasive material.
This utility model makes axle bed with flanger bearing bush without directly contact by dividing plate is increased on original structure.Work as wheel
When body is rotated, flanger bearing bush is also rotated together, and now axle bed and dividing plate are fixed.Exist between dividing plate and flanger bearing bush
Relative motion, at the faying face of the two, has friction, but flanger bearing bush belongs to high-abrasive material, can be very good protection wheel
Body is from abrasion.Meanwhile, the setting of dividing plate can be protected to axle bed so as to from friction, reduced the abrasion of axle bed, carried
High service life of the axle bed with wheel body.After dividing plate wears up to a certain degree, dividing plate is directly changed, axle need not be changed
Seat, reduces the cost of renewal part.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at Y in Fig. 1；
Fig. 3 is existing structural representation.
In figure：1st, alignment pin, 2, axle bed, 3, dividing plate, 4, flanger bearing bush, 5, wheel body.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of structure that can extend guide wheel, thrust wheel and support sprocket wheel axle bed service life, bag
Axle, axle bed 2, wheel body 5 and flanger bearing bush 4 are included, axle is arranged in axle bed 2, and wheel body 5 is mounted on an axle, and flanger bearing bush 4 is arranged on
Between wheel body 5, axle and axle bed 2, interference fit between wheel body 5 and flanger bearing bush 4, also including be fixedly mounted on flanger bearing bush 4 with
Dividing plate 3 at 2 faying face of axle bed, when wheel body 5 is rotated, flanger bearing bush 4 is also rotated together, and dividing plate 3 and axle bed 2 are maintained static,
Relative motion can be produced at flanger bearing bush 4 and 3 faying face of dividing plate, friction is produced, rub suffered by axle bed so as to be reduced.5 turns of wheel body
When dynamic, friction is produced in flanger bearing bush 4 and the faying face of dividing plate 3, is made axle bed 2 and wheel body 5 from fretting wear, is improve axle bed
With the service life of wheel body.After dividing plate or flanger bearing bush wear up to a certain degree, directly change, need not change axle bed with
Wheel body, reduces the cost of renewal part.Wherein, floating seal can be provided between wheel body and axle bed.
Preferably, the dividing plate 3 is arranged on axle bed 2 by alignment pin 1.As shown in figure 1, each on dividing plate 3 and axle bed 4
Four holes are bored, alignment pin 1 is fixed in 2 hole of axle bed, and then dividing plate 3 is fixed with axle bed 2.
Preferably, the material of the dividing plate 3 is high-abrasive material.
From said structure, this utility model makes axle bed and flanger bearing bush by dividing plate is increased on original structure
Without directly contact.When wheeling thereof, flanger bearing bush is also rotated together, and now axle bed and dividing plate are fixed.Dividing plate with
There is relative motion between flanger bearing bush, at the faying face of the two, have friction, but flanger bearing bush belongs to high-abrasive material,
Can be very good to protect wheel body from abrasion.Meanwhile, the setting of dividing plate can be protected to axle bed so as to from friction, reduced
The abrasion of axle bed, improves the service life of axle bed and wheel body.After dividing plate wears up to a certain degree, directly changing dividing plate is
Can, axle bed need not be changed, the cost of renewal part is reduced.
