Description
Technical field
This utility model relates to a kind of auger dustproof construction not using oil sealing.
Background technology
In foodstuff drying device field, the working environment of auger bearing is very severe, high temperature and dust content is high, the working life of bearing is the shortest, often damage, maintenance work just can must be completed by professional and technical personnel again, and dehydrator user generally requires the technical support waiting producer, largely effects on the drying operation of grain.
Currently, the dustproof construction of auger mainly uses oil sealing to add the sealing means of dust cap.The sealing of oil sealing is to be formed by the interference fit between a flexible seal (leather, rubber, politef, polytrifluorochloroethylene or polyimides etc.) and rotary shaft.Its sealing mechanism is: in the contact surface between oil sealing lip and axle simultaneously and deposit dry friction, boundary lubrication and three kinds of situations of fluid lubrication, be constantly alternately produced.Dry friction produces abrasion, and fluid lubrication produces leakage, under boundary lubrication, forms one layer of stable hydrodynamic oil film, oil film thickness about 0.0025mm between oil sealing lip and the interface of axle；This layer of oil film, in addition to being used as lubrication, also seals.Oil film is the thickest, and fluid will leak；Oil film is the thinnest, cannot form fluid lubrication film, and lip will wear and tear.Therefore, in order to obtain good sealing property and long working life, will ask for help oil sealing structure design, design for rubber formulation and installing and using, condition will be provided for forming thin and stable borderline oil film, wherein design in structure, install and use aspect, the condition of domestic conventional oil sealing defined is the harshest, auger bearing in foodstuff drying device field, it is particularly at the lower auger of grain heat-drying motor spindle, because of working environment very severe, with oil enveloping structure, bearing can not be sealed, therefore the working life of bearing is extremely short, lower auger type foodstuff drying device is caused normally to use.
Summary of the invention
In place of overcoming the deficiencies in the prior art, this utility model provides a kind of auger dustproof construction, to solve existing the problems referred to above.
This utility model be the technical scheme is that a kind of auger dustproof construction, including auger main shaft, this auger main shaft one end couples with the bearing being arranged in a suspended axle bearing, wherein said bearing is sequentially provided with dustproof gasket and protection catch towards described auger main shaft side, described dustproof gasket uses elastic abrasion-proof material to make, middle porose, be set on described auger main shaft and with its interference fit；Described protection catch uses metal to make, and it is fastened by screws together with described dustproof gasket on the side of described suspended axle bearing.
This utility model have employed Double-protection structure in auger the inner, wherein the protection catch of outer end effectively stops corn to enter Bearing inner in course of conveying, protect the dustproof gasket inside it not clashed into breakage by hard thing simultaneously, dustproof gasket is enclosed within auger main shaft with interference fit, the advantage of this structure is the degree of eccentricity to auger main shaft, dimensional discrepancy, out-of-roundness, surface roughness requirements is the loosest, contact surface between dustproof gasket lip and axle is dry friction, elastic abrasion-proof material owing to using has preferable wearability (such as elastic polyurethane high-abrasive material, anti-wear performance is 8 times of hard alloy steel, it it is 7 times of vulcanite, it it is 3 times of ultra high molecular polyethylene), therefore dustproof gasket has longer service life.
Further, described dustproof gasket uses high temperature resistant type elastic abrasion-proof material to make.Due to the working environment very severe of some auger, being particularly at the lower auger of grain heat-drying motor spindle, need dustproof gasket to have preferable high-temperature stability, the elastic polyurethane high-abrasive material heatproof of special type can reach 170 DEG C.
Further, described dustproof gasket preferred version uses high density polyethylene (HDPE) to make.High density polyethylene (HDPE) has high-density polyethylene olefinic environmental-protecting material, chemical stability is good, high temperature resistant, anti-wear performance is superior, with in auger main shaft friction process, as bigger in some position frictional force, the heating of friction position starts to melt after reaching fusing point, can form self-lubricating effect, it is not necessary to add machine oil, most suitable closure size is automatically formed after cooled and solidified, so that the gap of the two minimizes, form optimal sealing structure, there is the effect of self-forming.
Further, the opposite side of described bearing is provided with an outer end dust cover, and this outer end dust cover is fastened by screws on the side of described suspended axle bearing, and the outer end dust cover of auger can effectively prevent cereal-granules and dust from entering Bearing inner.
Beneficial effect: this utility model uses Double-protection structure in auger the inner; wherein the protection catch of outer end effectively stops corn to enter Bearing inner in course of conveying; protect the dustproof gasket inside it not clashed into breakage by hard thing simultaneously; dustproof gasket uses high-density polyethylene material wear-resisting, corrosion-resistant, resistant to elevated temperatures; fine particle and dust can be effectively prevented to enter between bearing inner race and roller; substantially increase the working life of bearing, reduce the fault rate of equipment.
Accompanying drawing explanation
The utility model will be further described the most in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
In figure: 1 auger main shaft, 2 suspended axle bearings, 3 bearings, 4 dustproof gaskets, 5 protection catch, 6 outer end dust covers, 7 suspension strut plates.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
