Description
Technical field
The present invention relates to a kind of cone crushers, and in particular to a kind of cone crusher degree of eccentricity regulating mechanism.
Background technology
Cone crusher is suitable for operation fine crushing in middle high rigidity material, is widely used in all kinds of minings and makees
Industry.The degree of eccentricity of cone crusher and stroke are crusher Specifeca tion speeification, and the degree of eccentricity influences its stroke, Jin Erying
Ring its crushing performance.For this purpose, the international mainstreams such as Sandvik producer uses double eccentric sleeves regulating mechanism.Pass through eccentric bushing in adjusting
Spindle eccentricity degree is adjusted with the fit angle of outer eccentric bushing, and then adjusts its stroke, to meet the needs of different operating modes.However,
Since axially bored line and outer circle axis are not parallel in interior eccentric bushing, the fit angle of inside and outside eccentric bushing is adjusted, main shaft will be caused
Different with complete machine axial space, main shaft can not be bonded with upper arm support bushing, and main shaft is point contact with upper arm support bushing, influences its master
Axis and upper arm support bushing stress.
Existing regulating mechanism includes：Outer eccentric bushing, lower bearing bracket, interior eccentric bushing, main shaft and upper arm support bushing, wherein interior eccentric
Set and upper arm support bushing are sliding bearing.The inner hole of the periphery of interior eccentric bushing and outer eccentric bushing, and transmitted by key
Power.Main shaft epimere is inserted into upper arm support bushing endoporus, and interior eccentric bushing endoporus is inserted into lower end.Pass through eccentric bushing in adjusting and outer bias
The fit keyway of set converts main shaft angle, adjusts cone crusher stroke.
Outer eccentric bushing is the interior axially bored line eccentric bushing parallel with outer circle axis.The endoporus of eccentric bushing is furnished with keyway.
Interior eccentric bushing is interior axially bored line and the not parallel eccentric bushing of outer circle axis.The periphery of interior eccentric bushing is furnished with multiple keys
Slot.
When not adjusting stroke, broken host main shaft intersects with complete machine axis.In shattering process, upper arm support bushing and main shaft
Line contacts, and stress is preferable.
But when adjusting stroke, broken host main shaft is different with complete machine axis.In shattering process, upper arm support bushing and master
Axis point contact, contact point stress are larger.Stress is excessive to be caused to fail to avoid contact with, the adjustable range of the stroke of existing scheme compared with
It is small.
Since axially bored line in eccentric bushing and outer circle axis are not parallel, its main shaft and complete machine axis will be led to by adjusting its inclination angle
Line is non-intersecting, and main shaft can not be bonded with upper arm support bushing, becomes point contact from line contact, and then influence its main shaft and upper arm support lining
Cover stress.Therefore, stroke adjustable range is typically small.
Invention content
Purpose：In order to overcome the deficiencies in the prior art, the present invention to provide a kind of cone crusher degree of eccentricity tune
Save mechanism.
Technical solution：In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of cone crusher degree of eccentricity regulating mechanism, it is characterised in that：Including outer eccentric bushing, key one, middle eccentric bushing, key
Two, interior eccentric bushing, main shaft, upper arm support bushing；
At least one keyway of arrangement, interior axially bored line are parallel with outer circle axis in outer eccentric bushing；
Middle eccentric bushing endoporus and periphery arrange that multiple keyways, interior axially bored line intersect with outer circle axis；
Interior eccentric bushing periphery arranges that at least one keyway, interior axially bored line intersect with outer circle axis；
The periphery of middle eccentric bushing is matched with the endoporus of outer eccentric bushing, and middle eccentric bushing endoporus and interior eccentric bushing periphery match
It closes；
Middle eccentric bushing is inserted into outer eccentric bushing endoporus, and is driven by key one；Eccentric bushing endoporus during interior eccentric bushing is inserted into, and passed by key two
It is dynamic；
When adjusting stroke, axis both clockwise or counterclockwise rotation of the middle eccentric bushing along outer eccentric bushing arrive assignment key groove location；It is interior inclined
Heart set is reversely rotated along the axis of middle eccentric bushing, arrives setting key groove location.
Adjust stroke（The degree of eccentricity）It need to synchronize and replace mating upper arm support bushing.
The main shaft epimere is inserted into upper arm support bushing endoporus, and interior eccentric bushing endoporus is inserted into lower end.
Preferably, the cone crusher degree of eccentricity regulating mechanism, it is characterised in that：The outer eccentric bushing
One keyway of interior arrangement.
Preferably, the cone crusher degree of eccentricity regulating mechanism, it is characterised in that：The interior eccentric bushing
Periphery arranges a keyway.
Further, the both sides of the key one keyway card with keyway and middle eccentric bushing periphery in outer eccentric bushing respectively
Connect cooperation.
Further, the both sides of the key two keyway with the keyway of middle eccentric bushing endoporus and interior eccentric bushing periphery respectively
It is engaged by clamping.
Advantageous effect：Cone crusher degree of eccentricity regulating mechanism provided by the invention can realize larger stroke tune
Adjusting range keeps main shaft and the contact of upper arm support bushing line, stress in adjustment process more reasonable.1., should in degree of eccentricity adjustment process
Mechanism realizes that crusher axis remains that line contacts with upper arm support bushing, and stress is evenly reasonable；2. the degree of eccentricity and stroke
Adjustable range bigger.
