Abstract
The utility model relates to a sealing device of an auger mechanism. The sealing device of the auger mechanism comprises a rotating shaft, the rotating shaft is a stepped shaft, a bearing is mounted on the stepped part of the rotating shaft, a cylindrical outer shell is mounted at one end of the rotating shaft, a pressing plate is mounted at one end of the outer shell, the pressing plate is of a boss-shaped structure, the protruding part of the pressing plate stretches into the outer shell, packing is mounted between the inner wall face of the outer shell and the outer wall face of the rotating shaft, and the packing is arranged tightly. A base plate is mounted on the peripheral surface of the outer shell, the base plate is connected with the pressing plate through a fastener, and a gasket is mounted between the base plate and the outer ring of the bearing through a fastener. The sealing device of the auger mechanism is compact and reasonable in structure, and convenient to manufacture and mount, the packing is made to generate radial expanding movement by squeezing the packing to achieve a sealing function, and the sealing device of the auger mechanism is simple in structure, low in cost, good in sealing effect, and capable of protecting the bearing and prolonging the service life of the bearing.
Description
Technical field
The utility model relates to sealing arrangement, especially a kind of sealing arrangement of auger mechanism.
Background technology
In the feeder of helical feed, the end float misalignment phenomenon of screw shaft is serious, the fine materials of higher order number particularly, as french talc (be white or off-white color, fine, without the powder of grittiness, hand touches with soapy feeling.Odorless, tasteless.This product is not all dissolved in water, the acid of rare ore deposit or rare alkali hydroxide solution.Can do medicinal.), its fineness is 400 orders, and granularity is 38um only, and its physical property is dry smooth, good flowing properties, its physical property is dry smooth, good flowing properties, has gap to scurry out.
Spiral feeder structure of the prior art, by helicallobe, rotate material is constantly carried, the rotating shaft two ends of helicallobe are installed installs by bearings, the sealing of bearing adopts seal ring or tightening seal washer sealing, in use, fine powder easily enters in bearing, causes grease emulsion deterioration, inefficacy, thereby cause bearing because of bad lubricated damage, shorten bearing service life.
Utility model content
The applicant in above-mentioned existing production technology etc. shortcoming, a kind of sealing arrangement of auger mechanism rational in infrastructure is provided, thereby reaches sealing effectiveness by the extruding of packing, good sealing effect, extends bearing service life, reduces costs.
The technical scheme that the utility model adopts is as follows:
A kind of sealing arrangement of auger mechanism, comprise rotating shaft, described rotating shaft is stepped shaft, the ladder place of described rotating shaft is provided with bearing, and one end of described rotating shaft is provided with cylindrical housing, and pressing plate is installed in one end of described shell, described pressing plate becomes boss shape structure, the projection of described pressing plate stretches in shell, between the internal face of shell and the outside wall surface of rotating shaft, packing is installed, described packing close-packed arrays; Be positioned on the outer circumference surface of shell substrate is installed, described substrate is connected with pressing plate by fastener, between described substrate and outside race, by fastener, packing ring is installed.
Further improvement as technique scheme:
Distance between the cascaded surface of described rotating shaft and pressing plate end face is 20mm-30mm.
The beneficial effects of the utility model are as follows:
The utility model compact conformation is reasonable, makes with easy for installation, utilizes the extruding to packing, thereby makes packing produce the motion of radial dilatation, realizes sealing function, and it is simple in structure, and cost is low, good sealing effect, and protection bearing, extends bearing service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, bearing; 2, packing ring; 3, substrate; 4, pressing plate; 5, shell; 6, packing; 7, rotating shaft.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the sealing arrangement of the auger mechanism of the present embodiment, comprise the rotating shaft 7 of auger mechanism, rotating shaft 7 is stepped shaft, and the ladder place of rotating shaft 7 is provided with bearing 1, one end of rotating shaft 7 is provided with cylindrical housing 5, pressing plate 4 is installed in one end of shell 5,4 one-tenth boss shape structures of pressing plate, and the projection of pressing plate 4 stretches in shell 5, between the internal face of shell 5 and the outside wall surface of rotating shaft 7, packing 6 is installed, packing 6 close-packed arrays; Be positioned on the outer circumference surface of shell 5 substrate 3 is installed, substrate 3 is connected with pressing plate 4 by fastener, between substrate 3 and bearing 1 outer ring, by fastener, packing ring 2 is installed.
Distance between the cascaded surface of rotating shaft 7 and pressing plate 4 end faces is 20mm-30mm.
In actual use procedure; because pressing plate 4 is under the effect of fastener; can push with packing 6; push compact arranged packing 6; packing 6 is toward the radial direction expansion of rotating shaft 7, and packing 6 can pack tightly rotating shaft 7, thereby reaches the effect of sealing; the powder entering in auger mechanism is blocked in outside rotating shaft 7, actv. protection bearing 1.Even in use, there is the tiny dust of part to enter in rotating shaft 7, also can between the cascaded surface of rotating shaft 7 and pressing plate 4 end faces, gap, flow away, further protect bearing 1.Its good sealing effect.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
