The sealing structure is simple and easy to mount and dismount, the oil leakage and oil seepage problems of the spider arm mechanism conveying arm transmission shaft are well solved, and production requirements are met.
Description
Technical field:
The utility model relates to a kind of sealing configuration of rolling connection unit spider transferring arm transmission shaft.
Background technique:
In process of production,, often there is leakage of oil, oil impregnate phenomenon in eight transferring arm parts on spider hand mechanism to PROTOS70 rolling connection unit, and the lubricant oil leaking out can easily pollute cigarette, thereby causes cigarette surface to have oil stain phenomenon, has directly affected quality of product.Eight transferring arms of spider are in maintenance simultaneously, backbone sealing ring on the transferring arm transmission shaft of most employing local replacing oil impregnate or replacing assembly, dismounting is extremely inconvenient, and change continually backbone sealing ring, the wearing and tearing to transmission shaft have been increased, also increase labor intensity and cost of production, affected equipment efficiency.
Spider hand mechanism is mainly that the cigarette of Double Length that cigarette-cutting system is transported is steadily sent on the smoke inlet wheel of spicing machine.
During machine operation, spider hand mechanism is revolution in the direction of the clock under the driving of main transmission, and eight transferring arms are along the circumferential direction installed in mechanism, and suction socket is all housed on every transferring arm.Transferring arm is by the gyration center turning anticlockwise of self, and the suction socket on transferring arm also turns round clockwise by the gyration center of self.Spider hand mechanism, transferring arm, suction socket equate with respect to the angular velocity of self gyration center, so no matter transferring arm where, suction socket is horizontal all the time.When transferring arm forwards lowest part to, suction socket holds cigarette from pass cigarette guide rail, when transferring arm forwards high order end position to, the cigarette that suction socket holds just in time aligns YJ27 type spicing machine and enters a wheel grain on cigarette drum, suction socket puts down cigarette, cigarette is drawn onto on cigarette drum, completes cigarette course of conveying.
For spider hand mechanism leakage of oil, oil impregnate phenomenon, after having been carried out analyzing, it finds that the easy oil impregnate of backbone sealing ring of two φ 28 * φ 20 * 5 on transferring arm transmission shaft causes the reason of leakage to mainly contain two aspects: the one, and gapped on sealing surface; The 2nd, there is pressure difference sealing both sides.Owing on equipment, running shaft being adopted to backbone sealing ring (nitrile butadiene rubber) mostly at present, and backbone sealing ring short-term cost performance is high, but long-time running comprehensive cost is very high; Simultaneously working life short (3000h), leak-down rate is high, and the axle journal that easily weares and teares causes the easily defect such as loss or pollution of lubricant oil.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of sealing configuration of rolling connection unit spider transferring arm transmission shaft, adopt the closed of new material, new technology, by the improvement to backbone sealing ring, design, reduced the efficiency that labor intensity and cost of production have improved equipment, guarantee quality of product, thereby obtained good economic benefit.
The utility model technical solution problem adopts following technological scheme:
A sealing configuration for rolling connection unit spider transferring arm transmission shaft, arranges the polyoxymethylene seal carrier of Step Shaft shape, and the small end excircle of described seal carrier is provided with outside thread; The large end internal chamber wall of seal carrier is along the circumferential direction provided with twice groove, is respectively equipped with this special envelope in described groove, and the large end outer wall of seal carrier is along the circumferential direction provided with groove, in described groove, is provided with fluororubber O-type ring.
On spatial position, described fluororubber O-type ring is between described in two, this spy seals.
Described in each, this special envelope is combined by a rubber o-ring and teflon circle, and rubber o-ring is tightly connected with seal carrier in groove inner side, and teflon circle protrudes from groove outside and forms sealing with transmission shaft outer wall.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The outside seal mechanism Environmental Conditions of transmission shaft is 80 ℃ of left and right, so carrier adopts polyoxymethylene (POM) making, this special envelope (fluororubber O-type ring adds teflon circle, is commercially available prod) of inner twice, outside one fluororubber O-type ring.This combination seal form is mainly from actual demand, the integral combined installation and removal of being convenient to seal ring position, minimizing maintenance man's workload; Adopt this special envelope form, be mainly that this special envelope has frictional force low, without creeping, the advantage such as tripping force is little, high pressure resistant, and groove structure is simple, apply two groups before and after after series connection this special envelope almost can reach hermetic effect.Novel sealing ring has following characteristics:
With the high polyoxymethylene of intensity (POM), as seal carrier, realize integral type assembling, for easy to assembly, on the small end excircle of seal carrier, designed screw thread, be equipped with the Assembly And Disassembly that corresponding screw thread cutting ferrule facilitates seal carrier;
Teflon (+20% carbon fiber+5% graphite) has good compressive strength, friction factor and friction factor are all very little, improve sealing self lubricity and reduce the wearing and tearing of seal ring to axle working life, seal ring is controlled effectively to the extent of injury of axle.
O type circle is most widely used a kind of Sealing in sealing industry always, its good airproof performance, and the life-span is long, kinetic friction resistance; Adopt fluorine rubber, mainly due to fluorine rubber, there is the characteristic of very high high temperature resistant, weather proof, anti-oxidant and resist chemical, be comparatively applicable to actual applying working condition.
This apparatus structure is simple, is easy to dismounting, has solved well the phenomenon of spider hand mechanism transferring arm transmission shaft leakage of oil, oil impregnate, has met the needs of producing.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 seal carrier, 2 outside threads, 3 these special envelopes, 4 fluororubber O-type rings.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: by reference to the accompanying drawings, the sealing configuration of the rolling connection unit spider transferring arm transmission shaft of the present embodiment, the polyoxymethylene seal carrier 1 of the Step Shaft shape of hollow is set, the small end excircle of seal carrier is provided with outside thread 2 (specification M24 * 1), be used in conjunction with the screw thread cutting ferrule mating with this outside thread, can easily seal carrier be fitted in the annular gap between transmission shaft and external casing, when changing, also be convenient to dismounting simultaneously.The large end internal chamber wall of Step Shaft shape seal carrier 1 is along the circumferential direction provided with twice groove (inner groovy), in groove, be respectively equipped with this special envelope 3, the large end outer wall of seal carrier 1 is along the circumferential direction provided with groove (outer groove) equally, is provided with fluororubber O-type ring 4 in groove.From spatial position, fluororubber O-type ring 4 is between two these special envelopes 3.In concrete application, each this special envelope is concentric circles state combination by a rubber o-ring and teflon circle and forms, and rubber o-ring is tightly connected with seal carrier in groove inner side, and teflon circle protrudes from that groove is outside forms sealing with transmission shaft outer wall.
