As preferably, also including guide collar, described connector is located in guide collar, and can move up and down along guide collar.
As preferably, the periphery of described balance ring set is additionally provided with liner as water tank, generally adopts and directly forms water tank on the peripheral solder iron plate of balance ring set, thus each parts are cooled down.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein, axostylus axostyle 1, lining the 2, first roller surface bearing the 3, second roller surface bearing 4, balance ring set 5, compression spring 6, oil sealing end cap 7, connector 8, oil fuel tube 9, annular boss 10, oil circuit through hole 11, guide collar 12, water tank 13.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention, after having read the present invention, the amendment of the various equivalent form of values of the present invention is all fallen within the application claims limited range by those skilled in the art.
nullAs shown in Figure 1，A kind of engineering machine balancing controls system，Including axostylus axostyle，Lining、First roller surface bearing、Second roller surface bearing、Balance ring set、Compression spring、Bearing (ball) cover、Oil sealing end cap、Connector and oil fuel tube，Described balance ring set is fixed on the bottom of connector and inwall is provided with the annular boss for fixing bearing，The blind hole being provided with accommodation compression spring that the upper and lower surface of described annular boss is corresponding respectively，Described lining is enclosed within axostylus axostyle，And between lining and axostylus axostyle, it is provided with oil-sealing sleeve，Described first roller surface bearing is located on lining and is positioned at annular boss upper surface，Described second roller surface bearing is located on lining and is positioned at the lower surface of annular boss，It is respectively provided with compression spring in two blind holes of described annular boss upper and lower surface，This compression spring is corresponding first roller surface bearing and the second roller surface bearing respectively，Described bearing (ball) cover is located at the upper end of the first roller surface bearing，Described oil sealing end cap is fixed on the bottom of balance ring set and cooperatively forms sealing with oil-sealing sleeve，Described annular boss、Bearing (ball) cover and lining are equipped with oil circuit through hole，Described oil fuel tube connection oil sealing end cap，Lubricating oil is made to flow through each oil circuit through hole successively，Thus providing lubrication to the contact surface of parts each in balance adjustment assembly；Described axostylus axostyle and described compression spring all adopt high-strength stainless steel material, and described oil fuel tube selects pvc material to make.As preferably, also including guide collar, described connector is located in guide collar, and can move up and down along guide collar.As preferably, the periphery of described balance ring set is additionally provided with liner as water tank, generally adopts and directly forms water tank on the peripheral solder iron plate of balance ring set, thus each parts are cooled down.
Connector moves up and down so that balance ring set and moving up and down along guide collar under the effect of driving mechanism, thus position is adjusted in real time.Axostylus axostyle generally connects impeller unit, but starting moment, axostylus axostyle is affected by liquid stream can produce instantaneous deboost, thus axostylus axostyle is produced skew, now in the compression bolt of balance ring set annular boss upper and lower surface, roller surface bearing is played buffering Accommodation, adopting upper and lower two groups of plane bearings in the present invention is utilize plane bearing tyrannical to resistance to compression offset behavior, and both direction all can play cushioning effect up and down, thus strengthening its self-balancing ability.It addition, the lubricating system of the present invention is more exquisite, the lubricating oil of oil fuel tube filling flows upwardly through successively to two plane bearings lubrications along the oil circuit through hole of balance ring set, then through the oil circuit through hole of bearing headkerchief and to the contact surface offer lubricating oil between lining and axostylus axostyle.
Above-mentioned detailed description of the invention is used for illustrating the present invention, rather than limits the invention, in the spirit and scope of the claims of the present invention, and any amendment that the present invention is made and change, both fall within protection scope of the present invention.
