Abstract
The utility model discloses a kind of overall roller breaker roll, including roll shaft, key is connected with two wheel hubs on the roll shaft, global formation has roller on the wheel hub, one of them is provided with fixing device for wheel hub between the wheel hub and the roll shaft, have the free degree moved axially along the roll shaft between another wheel hub and the roll shaft；The utility model is simple in construction, greatly reduces assembly process and processing cost；The damage to element and structure will not be produced after roller expansion simultaneously, the influence of swelling internal stress is greatly reduced.
Description
Technical field
The utility model is related to kibbler roll technical field, more particularly to a kind of overall roller breaker roll.
Background technology
Breaker roll is the important component of kibbler roll, is used existing breaker roll more and wheel is installed between roll shaft and outer roller
The design of hub, such design adds the processing cost of breaker roll and the fussy degree of assembling.In addition, in disintegrating machine work
When, the outer roller of breaker roll be able to can be all deformed because temperature is raised and expands in axially and radially direction, this to become
Shape can produce destruction to fastener axially and radially.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure and assembles simple, effective reduction thermal expansion shadow
A kind of loud overall roller breaker roll.
In order to solve the above technical problems, the technical solution of the utility model is：Overall roller breaker roll, including roll shaft, institute
Stating key on roll shaft and being connected with global formation on two wheel hubs, the wheel hub has roller, one of them described wheel hub and the roll shaft
Between be provided with fixing device for wheel hub, between another wheel hub and the roll shaft have along the roll shaft move axially the free degree.
It is interference as preferred technical scheme, between the wheel hub and the roll shaft provided with the fixing device for wheel hub
Coordinate, with matching somebody with somebody between the wheel hub and the roll shaft along the roll shaft freedom of axial movement for interference fits or gap
Close.
As preferred technical scheme, the fixing device for wheel hub includes being arranged on the roll shaft and in the wheel hub
Locking nut positioned at the wheel hub lateral surface is installed on the positioning shaft shoulder of side, the roll shaft.
As preferred technical scheme, the wheel hub is provided with through hole.
By adopting the above-described technical solution, overall roller breaker roll, including roll shaft, key is connected with two on the roll shaft
Global formation has roller on wheel hub, the wheel hub, and fixing device for wheel hub is provided between one of them described wheel hub and the roll shaft,
There is the free degree moved axially along the roll shaft between another wheel hub and the roll shaft；The beneficial effects of the utility model are：
1. simple in construction, the roller and the wheel hub monoblock cast, main assembling only have the roll shaft and the wheel hub
Assembling, greatly reduce assembly process and processing cost；
2. by the fixation only to the wheel hub at one, the axially and radially internal stress of the roller thermal expansion is not present
Influence to structure or element, is effectively reduced the damage that thermal expansion is brought.

Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As depicted in figs. 1 and 2, key is connected with two wheel hubs 2 on overall roller breaker roll, including roll shaft 1, the roll shaft 1,
Global formation has a roller 3 on the wheel hub 2, the wheel hub 2 and the monoblock cast of roller 3, greatly reduce processing cost and
Assembly process.
One of them is provided with fixing device for wheel hub 4, another wheel hub 2 and the roll shaft between the wheel hub 2 and the roll shaft 1
There is the free degree moved axially along the roll shaft 1 between 1, radial-axial after the guarantee expanded by heating of roller 3 is designed with this
All without generation to element or structural damage.
It is interference fit between the wheel hub 2 and the roll shaft 1 provided with the fixing device for wheel hub 4, this wheel hub 2 is also set
There is fixing device for wheel hub 4, ensure that wheel hub 2 described herein is fixed with double design；With along the roll shaft 1 axial movement from
It is that with interference fits or gap, this wheel hub 2 needs to guarantee to slide, between the wheel hub 2 and the roll shaft 1 spent
Ask cooperation will pine.
The fixing device for wheel hub 4 includes being arranged on the roll shaft 1 and in the positioning shaft shoulder of the medial surface of wheel hub 2
41, the locking nut 42 positioned at the lateral surface of wheel hub 2 is installed, by the positioning shaft shoulder 41 and described on the roll shaft 1
Locking nut 42 clamps a wheel hub 2 to realize fixation, while it is anti-loosening to increase stop washer 43.
The wheel hub 2 is provided with through hole 5, and the setting one of the through hole 5 is the interior space for linking up the roller 3, plays certain
Thermolysis；Two are the reduction of the weight of the roller 3.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
