Description
Technical field
The present invention relates to jaw crusher technical field, is more particularly that a kind of twin shaft for jaw crusher exempts from flywheel motion mechanism.
Background technology
Jaw crusher, being commonly called as jaw and breaking, is one of with the longest history, most popular disintegrating apparatus.
Jaw breaks equipment and there is a distinct surface, and namely the flywheel of a pair heaviness is housed, and this is unique in all disintegrating machine types.This flywheel has following features: 1. heavy (weight accounts for 15% of complete machine); 2. in pairs and be arranged symmetrically with (each one of left and right, wherein is provided with V belt groove, motor-driven driven pulley of holding concurrently); 3. edge is respectively provided with an eccentric balance pouring weight.
It is closely bound up with these parts of eccentric shaft wherein that jaw breaks equipment configuration flywheel.Eccentric shaft is that jaw breaks parts most crucial in equipment, and the jaw jaw broken in crushing pair comes from the bias design of eccentric shaft once the crushing motion of a tight pine when broken material.
The structure that prior art jaw is broken is as follows: connect shelves and be arranged in the middle of eccentric shaft, be followed successively by capacity eccentric bearing shelves, concentric bearings shelves, locking shelves, benchmark shelves from inside to outside, and both sides is arranged symmetrically with; Capacity eccentric bearing shelves are arranged with bearing, and bearing is arranged on dynamic jaw; Concentric bearings shelves are also arranged with bearing, and bearing is arranged in frame; The swing tooth plate of crushing pair and fixed tooth plate are contained in dynamic jaw and frame respectively; When eccentric shaft operates centered by rotation centerline, the swing tooth plate be contained on dynamic jaw carries out the broken work done of a tight pine with eccentric motion.
The bias design of eccentric shaft, while meeting the broken work done of jaw, also brings the problem such as " rotation eccentric moment of inertia ", " the reciprocal eccentric moment of inertia of gravity " and " the eccentric moment of inertia of work done ".
" rotation eccentric moment of inertia " is because eccentric shaft has eccentric shelves, when the eccentric weight of the eccentric shelves of eccentric shaft time rotational will produce eccentric moment of inertia, is called rotation eccentric moment of inertia.
" the reciprocal eccentric moment of inertia of gravity " is sheathed dynamic jaw on the eccentric shelves because of eccentric shaft, and dynamic jaw has gravity, when eccentric shaft time rotational will pull dynamic jaw to pump, produces eccentric moment of inertia, is called the reciprocal eccentric moment of inertia of gravity.
" work done eccentric moment of inertia " causes by load during work done is uneven, and traditional jaw is broken is the type (flywheel turns around, half way work done, another half way backhaul not work done) of typical half way work done.When jaw breaks work done because of the moment of inertia of the uneven generation of load, be called the eccentric moment of inertia of work done.
Above-mentioned produced eccentric moment of inertia must manage to eliminate, otherwise tight very harmful to the normal operation of machinery, totally unfavorable to disintegrating machine.
In order to overcome above-mentioned defect, prior art jaw is broken, and by setting up a pair flywheel, (wherein one is provided with V belt groove, have power transmission effect concurrently, also known as sheave), and a balance weight is set on flywheel, its balance weight is used for balancing the eccentric moment of inertia (orientation, balance weight place on flywheel is contrary with the eccentric centerline direction on eccentric shaft, and eccentric moment is equal) of eccentric shaft; The rotating inertia force of heavy flywheel is then for overcoming " eccentric gravity reciprocal inertia force square " and " eccentric work done moment of inertia " (utilize the corresponding quality of flywheel, on-stream kinetic energy store function to balance the moment of inertia of discontinuity).
The method that above-mentioned prior art solves eccentric vibrating has following deficiency:
If 1. rotation eccentric moment of inertia can also solve with self-balance method, so the reciprocal eccentric moment of inertia of gravity is congenital incurable disease in single eccentric shaft mechanism, cannot solve at all.
2. the half way work done characteristic that traditional jaw breaks also is that jaw breaks intrinsic congenital drawback, is also at all insurmountable under unit eccentric shaft mechanism.
3. rotation eccentric moment of inertia need balance with the counterweight block on flywheel, eccentric gravity reciprocal inertia force square and eccentric work done moment of inertia need balance with a pair heavy flywheel increased, Shi Epo mechanism is complicated, increases material cost, manufacturing cost and operation wasted work;
4. break in device fabrication at jaw, be difficult to the levels of precision (eccentric block shortage in weight or exceed and the error in eccentric orientation all can produce eccentric vibrating) detecting its moment of inertia balance, therefore all do not make balance when general jaw breaks product export and detect.Therefore, prior art jaw is broken in use, and eccentric vibrating can make related components produce fatigue damage, reduces its service life, and the bolt wherein connecting disintegrating machine and stand easily ruptures, and changes frequent; Eccentric moment of inertia then increases wasted work and produces noise because of vibration.
Prior art eccentric shaft has two center lines, i.e. rotation centerline and eccentric center line.Be in eccentric shaft centre position, and be connected to the connection gear of the capacity eccentric bearing gear on both sides, be perhaps for easy to process or custom, its center line connecting gear is all arranged on the eccentric center line of capacity eccentric bearing gear.Connection gear and capacity eccentric bearing gear all produce eccentric moment of inertia, and are jointly balanced by the flywheel eccentric balancing blocks of outer setting.
Technical scheme of the present invention is: the first, first realizes eccentric shaft homeostasis with self-balancing eccentric shaft, i.e. rotation eccentric inertia balance; The second, then combine with double-eccentric shaft, and make both eccentric reverse design, realize the reciprocal eccentric inertia force anomaly weighing apparatus of gravity; 3rd, finally with dual-crank-rocker mechanism design, former and later two crank and rocker mechanisms are staggered motion, realize the eccentric inertia force anomaly of work done and weigh.
After achieving three eccentric moments of inertia balances such as above-mentioned " rotations, gravity back and forth and work done ", then can exempt the flywheel of a pair heaviness.
Architectural feature of the present invention is: 1. internal feature (three): connecting the offside that the barycenter of shelves is arranged on eccentric center line is first remarkable architectural feature of the present invention; It is second remarkable architectural feature of the present invention that double-eccentric shaft oppositely engages running by a pair synchromesh gear; The motion of staggering of former and later two crank and rocker mechanisms in dual-spindle dual-crank rocker mechanism is the 3rd remarkable architectural feature of the present invention.2. surface: the 4th remarkable architectural feature of the present invention be eliminate flywheel and on eccentric balancing blocks.
Core technology of the present invention is: adopt " two that eccentric shaft is contrary eccentric center line designs ", " two self-balancing eccentric shaft combination and make its eccentric contradictory design scheme " and " former and later two crank and rocker mechanisms in dual-crank-rocker mechanism stagger work done design ", and above-mentioned three schemes are combined into one, realize the comprehensive eccentric moment of inertia self-balancing of disintegrating machine.
Jaw is broken establishes flywheel, is typical feature (other disintegrating machines are such as strikeed back brokenly, hammer broken, impact cutting, roll-type are broken and circular cone is broken does not all arrange flywheel).Allow jaw break taking leave of flywheel is use the remarkable effect after core technology of the present invention, is the last important technical revolution of jaw crusher development history, is also an important milestone.
