Further, the power transmission shaft of Single-Cylinder Hydraulic Cone Crusher is arranged in drive shaft mount by bearing, one end of power transmission shaft is fixed with the first conical gear, and the other end is fixed with belt pulley or shaft coupling, and the first conical gear engages with the second conical gear being fixed on eccentric bushing.
The utility model also provides a kind of Single-Cylinder Hydraulic Cone Crusher that comprises above-mentioned Single-Cylinder Hydraulic Cone Crusher overload protection arrangement.
The beneficial effects of the utility model are: the parts that can effectively prevent Single-Cylinder Hydraulic Cone Crusher damage because of overload, improve disintegrating machine operating rate, reduce production costs.
Brief description of the drawings
Fig. 1 is the part schematic diagram that the Single-Cylinder Hydraulic Cone Crusher of Single-Cylinder Hydraulic Cone Crusher overload protection arrangement of the present utility model has been installed;
Fig. 2 is the part enlarged diagram of Fig. 1.
Detailed description of the invention
Technical scheme in the utility model embodiment is carried out to clear, complete description below.
Fig. 1 is the part schematic diagram that the Single-Cylinder Hydraulic Cone Crusher of Single-Cylinder Hydraulic Cone Crusher overload protection arrangement of the present utility model has been installed.Fig. 2 is the part enlarged diagram of Fig. 1.As depicted in figs. 1 and 2, the power transmission shaft 12 of Single-Cylinder Hydraulic Cone Crusher is arranged in drive shaft mount 11 by (or rolling) bearing that slides, and one end of power transmission shaft 12 is fixed with the first conical gear 14, and the other end is fixed with belt pulley 13(or shaft coupling).The first conical gear 14 engages with the second conical gear 6 being fixed on eccentric bushing 15.Eccentric bushing 15 is sleeved on main shaft 4.At Single-Cylinder Hydraulic Cone Crusher, under erectility, the top of main shaft 4 is by the axle sleeve horizontal support on upper frame 8.The bottom of main shaft 4 is supported on the top of cylinder plunger 1 by thrust bearing 16.Mantle 7 is fixedly mounted on the middle part of main shaft 4.The center line of the external cylindrical surface of the center line of the inner cylinder face of eccentric bushing 15 and eccentric bushing 15 intersects with a special angle.In the time that eccentric bushing 15 rotates, can drive the main shaft 4 that is arranged in eccentric bushing 15 inner chambers to carry out swing campaign together with mantle 7, realize crushing action.
The rolled mortar wall 9 matching with mantle 7 is fixedly mounted in upper frame 8, and upper frame 8 is arranged on lower frame 10.The interior cylinder plunger 1 that arranges of hydraulic cylinder 3, has formed the hydraulic fluid chamber 18 that is positioned at hydraulic cylinder 3 bottoms and the lubricant reservoir 17 that is positioned at hydraulic cylinder 3 middle parts.The hydraulic fluid chamber 18 of hydraulic cylinder 3 bottoms is communicated with accumulator 5 by high pressure resistant pipe, and the lubricant reservoir 17 at hydraulic cylinder 3 middle parts was both communicated with the oil-in (not shown) of hydraulic cylinder 3 sides, is communicated with again with the oil leab of thrust bearing 16.
The utility model is communicated with by the unloader (being called again pressure-reducing valve, overflow valve or safety valve) 2 that can make liquid flow to lubricant reservoir 17 from hydraulic fluid chamber 18 between the hydraulic fluid chamber 18 of hydraulic cylinder 3 and lubricant reservoir 17, in the time that hydraulic fluid chamber 18 pressure exceed setting value, part high pressure liquid force feed enters the lubricant reservoir 17 of low pressure by the unloader 2 being arranged in cylinder plunger 1, and the hydraulic coupling peak value of hydraulic fluid chamber 18 reduces greatly.
In disintegrating machine overload, that is:, when the hydraulic coupling of hydraulic fluid chamber 18 exceedes setting value, unloader 2 is opened, and the hydraulic fluid chamber of hydraulic cylinder 3 18 is communicated with lubricant reservoir 17, and hydraulic oil is arranged into lubricant reservoir 17 from hydraulic fluid chamber 18.
Accumulator 5 is for overload protection, and in the time that the hydraulic coupling of hydraulic fluid chamber 18 improves, part hydraulic oil enters into accumulator 5, realizes overload protection; In accumulator 5, be filled with gases at high pressure (for example, nitrogen), enter the further compressing high pressure gas of hydraulic oil of accumulator 5; Over time, the hydraulic oil in accumulator 5 can flow back to hydraulic fluid chamber 18 under pressure.
