Connecting axle 6 two ends are separately installed with the guide runner 61 suitable with gathering sill 31.
Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion or oscillating motion by hydraulic cylinder.Its structure is simple, reliable operation.When realizing moving back and forth with it, can deceleration device be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.The pressure reduction on hydraulic cylinder power output and piston effective area and both sides thereof is directly proportional.
According to the version of conventional hydraulic cylinder, following several types can be divided into:
1, piston type single-piston-rod hydraulic cylinder only has one end to have piston rod.
2, plunger-type cylinder is a kind of single-acting formula hydraulic cylinder, and can only realize the motion in a direction by hydraulic coupling, plunger backhaul will lean on the deadweight of other external force or plunger.Plunger only supports by cylinder sleeve and does not contact with cylinder sleeve, and such cylinder sleeve is very easily processed, therefore is suitable for doing Long travel hydraulic cylinder; Plunger total pressurized during work, thus it must have enough rigidity; Plunger weight is often comparatively large, easily sagging because of deadweight during horizontal positioned, cause seal and guiding uneven wear, therefore it vertically uses more favourable.
3, telescoping hydraulic cylinder has secondary or multi-level piston, and the order that in telescoping hydraulic cylinder, piston stretches out is from big to small, and unloaded order of retracting is generally then from small to large.Telescoping hydraulic cylinder can realize longer stroke, and when retracting, length is shorter, and structure is comparatively compact.This kind of hydraulic cylinder is usually used on engineering machinery and agricultural machinery.
4, spiral swing hydranlic pressure jar is output torque and realizes reciprocating executive component, also claims oscillatory motor.There are single blade and twayblade two kinds of forms.
The quality of the crudy of piston rod directly affects the life and reliability of whole product.Piston rod processing request is high, and its surface roughness requirements is Ra0.4 ~ 0.8um, requires strict to axiality, wearability.
