Description
Technical field
The invention belongs to mining machinery and manufacture field, especially belong to hydro cone-crusher and manufacture field, particularly hydro cone-crusher spherical bearing material selection.
Background technique
Single-Cylinder Hydraulic Cone Crusher is the broken common equipment of mining.Main frame broken material be by main shaft assembly eccentric bushing forced to move under around a stationary axle swing campaign, thus leave the rolling mortar wall surface be packed in frame time close when making the crushing wall of gyratory crusher, ore is constantly impacted in crusher chamber, extruding and flecition and realize the fragmentation of ore.Material enters crusher chamber by the feeding funnel being installed on top, is discharged after fragmentation by below discharge gate.
Assembling spherical bearing top, main shaft assembly bottom, relies on the spherical bearing bottom on piston body top, spherical bearing midfoot support.Main shaft assembly is when doing swing campaign, and spherical bearing top forms coordinating of dynamic pressure plain thrust bearing form with in the middle part of spherical bearing, between spherical bearing bottom.
Single-Cylinder Hydraulic Cone Crusher spherical bearing adopts cast bronze alloy and Alloy Constructional Steel to coordinate usually.Because Cu alloy material is rare, manufacture cost is higher.And bronze material Young's modulus higher (103GPa), be not easy after being subject to active force produce elasto plastic deformation, therefore during spherical bearing sliding movement to processing dimensional accuracy, form and position tolerance and surface roughness requirements higher.

Technological scheme is: a kind of installation method of Single-Cylinder Hydraulic Cone Crusher, comprises the following steps:
Above-mentioned spherical bearing top is adopted locating stud location, the fastening main shaft underpart that is assemblied in of high-strength bolt forms main shaft assembly;
Locating stud location and installation is adopted above-mentioned spherical bearing bottom to form piston assembly in end on the piston body;
Piston assembly is loaded oil hydraulic cylinder;
To be arranged on spherical bearing lower spherical in the middle part of above-mentioned spherical bearing;
Load main shaft assembly.
Compared with prior art, beneficial effect of the present invention is:
After spherical bearing top of the present invention, spherical bearing bottom adopt nylon material, because having lower melt viscosity, flowing fast.Be easy to mold filling, mold filling after coagulation point is high, energy rapid shaping, therefore molding cycle is short, and manufacturing efficiency is high.Nylon is that Maranyl is made, and material is also more conventional, and therefore the spherical bearing cost of raw material of nylon material is very cheap relative to Cuprum alloy.On the other hand, the running-in ability of nylon is good, can reduce the impact because of machining error, coaxiality error, surface roughness in the period of adjustment, and make contact even, area of contact increases, thus reduces frictional force, wear intensity.The embeddability of nylon is good, and energy good embedding Tibetan extraneous particles is to reduce the wearing and tearing of axle journal.The Young's modulus of nylon is little, and it self elasto plastic deformation can be relied on to compensate the bad friction compliance of slip surface initial engagement.Because these characteristics of nylon, so also can meet usage requirement adding can suitably to reduce tolerance of size and form and position tolerance man-hour, manufacture cost is corresponding reduction also.And Alloy Constructional Steel is quenched, temper number is high, intensity is high, is highly resistant to abrasive wear, fatigue wear and tribochemical wear.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-4, a kind of Single-Cylinder Hydraulic Cone Crusher spherical bearing, to comprise in the middle part of spherical bearing top 4, spherical bearing 5 and spherical bearing bottom 6.
Spherical bearing top 4 is Maranyl spherical bearing top, and spherical bearing bottom 6 is Maranyl spherical bearing bottom, in the middle part of the Alloy Constructional Steel spherical bearing in the middle part of spherical bearing 5 for quenching, after tempering.
Spherical bearing top 4 is second convex spherical shape, and medium position has high-strength bolt mounting hole 21.
In the middle part of spherical bearing, 5 is symmetrical concave spherical up and down, has axially lubrication main oil-hole 51 and radial oilhole 52 in 5 in the middle part of spherical bearing.
Spherical bearing bottom 6 is first convex spherical shape, and spherical bearing bottom 6 lower left quarter has locating stud mounting hole 61, and centre is provided with oilhole 63, and bottom is provided with positioning step 64.
During making, spherical bearing top 4 and spherical bearing bottom 6 adopt Maranyl casting respectively or use that then Maranyl bar is first rough turn processes sphere, last processing oil groove, boring on numerically controlled lathe.
In the middle part of spherical bearing, 5 adopt Alloy Constructional Steel first rough turn, then quench, temper after quenching, last finish turning sphere, boring.
Assembling is entered after above-mentioned machining.
During assembling, first adopt locating stud 8 to locate on spherical bearing top 4, fastening main shaft 1 underpart that is assemblied in of high-strength bolt 2 forms main shaft assembly.Spherical bearing bottom 6 adopts locating stud 8 location and installation to form piston assembly in piston body 7 upper end portion.During general assembly, first piston assembly is loaded oil hydraulic cylinder 3; 5 will to be arranged on the sphere of spherical bearing bottom 6 in the middle part of spherical bearing again.Finally, main shaft assembly is loaded.
When Single-Cylinder Hydraulic Cone Crusher after installing uses in the middle part of spherical bearing top 4, spherical bearing 5 and spherical bearing bottom 6 form the cooperation of dynamic pressure plain thrust bearing form.
Adopt nylon material due to spherical bearing of the present invention and quench, alloyed steel after tempering with the use of rear, the Yin Nilong cost of raw material is cheap, also not high to requirement on machining accuracy, so the spherical bearing price of often overlapping nylon material saves more than 500 yuan.And, spherical bearing of the present invention adopt nylon material and quench, alloyed steel after tempering with the use of rear, the running-in ability of Yin Nilong is good, self have self lubricity, and therefore between spherical bearing, friction factor is little, and heating value reduces, and bearing wear resistance improves.Nylon material embeddability is good, to the impurity in lubricant oil and dirt insensitive, can good embedding Tibetan extraneous particles, to reduce the wearing and tearing to bearing itself.Because these characteristics of nylon, the spherical bearing made of nylon is after production and application, and working life coordinated the spherical bearing made to be enhanced about more than once than former Cuprum alloy with alloyed steel.
