Abstract
Both there is good wearability, lubricity, absorb shock resistance and higher compression strength the present invention relates to a kind of, the Single-Cylinder Hydraulic Cone Crusher excentric sleeve for seizing phenomenon generation can be effectively eliminated again, excentric sleeve is covered for hollow eccentric shaft and is cast using gray cast iron, excentric sleeve upper end is provided with positioning compression slot, excentric sleeve lower end is provided with support bracket, and excentric sleeve inner wall is provided with oil groove.Advantage：First, the purpose of excentric sleeve self-lubricating was both realized, play the role of again from shock absorbing, and in the case of becoming smaller in inside and outside copper sheathing gap or in the case that machining accuracy can not ensure, avoid the generation for seizing phenomenon, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher；Second is that processing cost is low, easily replaces, achieve unexpected economic benefit and social benefit.
Description
Technical field
Not only there is good wearability, lubricity, absorb shock resistance and higher compression strength, but also can the present invention relates to a kind of
The Single-Cylinder Hydraulic Cone Crusher excentric sleeve for seizing phenomenon generation is effectively eliminated, belongs to Special Eccentric axle sleeve manufacturing field.
Background technology
At present in Single-Cylinder Hydraulic Cone Crusher, excentric sleeve is made of steel, i.e. ZG270-500.Its deficiency
Place：Although steel has high and uniform hardness and wearability, since steel does not have lubricity and absorb shock resistance in itself,
When making the excentric sleeve of single cylinder gyratory crusher, it can not both realize self-lubricating, can not also play the role of from shock absorbing, thus pole
The damage of excentric sleeve is easily caused, and replacement cost is high；Secondly as the coefficient of expansion of steel is big, become in inside and outside copper sheathing gap
In the case of small or in the case that machining accuracy can not ensure, easily generate and seize, cause Single-Cylinder Hydraulic Cone Crusher can not
Normal work.
Invention content
Purpose of design：Avoid the shortcoming in background technology, design is a kind of both had good wearability, lubricity,
Absorb shock resistance and higher compression strength, and will not cause to seize the Single-Cylinder Hydraulic Cone Crusher excentric sleeve of phenomenon generation.
Designing scheme：In order to realize above-mentioned purpose of design.The present invention is in structure design：1st, excentric sleeve uses gray cast iron
The design formed is cast, is one of the technical characteristic of the present invention.The purpose designed in this way is：Since the carbon in gray cast iron is main
With the formal distribution of flake graphite in metallic matrix, fracture is in dark gray, thus gray cast iron can be regarded as the base of steel
Body is formed plus flake graphite, and graphite is with existing for sheet in gray cast iron, thus it not only has good wearability, lubrication
Property, absorb shock resistance, machinability and higher compression strength, and processing cost is low, and it is convenient to replace.More importantly：Due to
Expansion Coefficient of Cast Iron is small, therefore has both made the situation that in the case of becoming smaller in inside and outside copper sheathing gap or machining accuracy can not ensure
Under, it will not cause to seize phenomenon, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher.2nd, excentric sleeve upper end is provided with fixed
Position pressing groove lower end is provided with the design that bracket, inner wall is supported to be provided with oil circuit, is the two of the technical characteristic of the present invention.It designs in this way
Purpose is：First, the design of positioning compression slot, makes the excentric sleeve between inner sleeve and housing realize reliable location, keeps away
Damage of the excentric sleeve to inside and outside copper sheathing is exempted from；Second is that the design of support bracket, makes interior copper sheathing be in supporting in dynamic duty
State, the generation of sinkage caused by avoiding interior copper sheathing under the action of the alternating load；Third, the design of oil circuit, it is ensured that
The recycling of lubricating oil and good cycle between inside and outside copper sheathing.
Technical solution：A kind of Single-Cylinder Hydraulic Cone Crusher excentric sleeve, excentric sleeve are covered and are used for hollow eccentric shaft
Gray cast iron is cast, and excentric sleeve upper end is provided with positioning compression slot, excentric sleeve lower end is provided with support bracket, in excentric sleeve
Wall is provided with oil groove.
The present invention is compared with background technology, first, not only having realized the purpose of excentric sleeve self-lubricating, but also plays the work from shock absorbing
With, and in the case of becoming smaller in inside and outside copper sheathing gap or in the case that machining accuracy can not ensure, avoid the production for seizing phenomenon
It is raw, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher；Second is that processing cost is low, easily replaces, achieve unexpected
Economic benefit and social benefit.

Specific embodiment
Embodiment 1：With reference to attached drawing 1-3.A kind of Single-Cylinder Hydraulic Cone Crusher excentric sleeve, excentric sleeve 1 are hollow inclined
It spindle sleeve and is cast using gray cast iron, gray cast iron uses HT250, and HT250 fractures are in dark gray.1 upper end of excentric sleeve
Be provided with positioning compression slot 2, excentric sleeve lower end is provided with support bracket 3,1 inner wall of excentric sleeve is provided with oil groove 4.Hollow eccentric shaft set
The degree of eccentricity of inner wall be 0.700---0.750 degree, best 0.732 degree.2 slot bottom of positioning compression slot is provided with and the matched screw thread of bolt
Wire hole, support 3 slot bottom of bracket are provided with and the matched thread filament hole of bolt.1 outer wall of excentric sleeve has concave arc shape slot 5 from top to bottom,
The concave arc shape slot 5 forms plug-in lubricant reservoir with outer copper sheathing inner wall, so as to play external copper sheathing during eccentric rotary
The forced lubrication of inner wall and itself wall.
It is to be understood that：Although above-described embodiment contrasts to the mentality of designing of the present invention, detailed word is retouched
It states, but these word descriptions, only the simple text of mentality of designing of the present invention is described rather than to mentality of designing of the present invention
Limitation, any combination, increase or modification without departing from mentality of designing of the present invention each fallen in protection scope of the present invention.
