Description
Technical field
The utility model is new to be related to conveying worm transportation art, particularly belongs to be applied to food, chemical industry, medicine, grain
Eat the conveying worm Anti-powder-leakage associated sealing arrangement for bearings of industry.
Background technology
In chemical industry, food, medicine, Grain Trade, material is required for the conveying of distance, and conveying worm is in this feelings
The mode of movement commonly used under condition.When in use, often there is both ends seal receptacle because poorly sealed, sealed end in existing conveying worm
Material reveals serious material leakage, and leakage is penetrated into bearing, will result in the bearing of conveying worm operating a period of time bearing block
Will be stuck.Material waste is will also result in simultaneously, pollutes environment.
Utility model content
The purpose of this utility model is to provide a kind of conveying worm Anti-powder-leakage associated sealing arrangement for bearings, be chemical industry, medicine,
The conveying worm that grain, food service industry use provides a kind of sealing device simple and reasonable for structure, solves spiral material leakage, prevents
The problem of dust.
In order to achieve the above object, the technical solution of the utility model is as follows：
A kind of conveying worm Anti-powder-leakage associated sealing arrangement for bearings, includes the axle sleeve being installed on helical axis, tune of usheing to seat
Mandrel is held, and end cover is gripped between axle sleeve and self-aligning bearing of usheing to seat, and end cover is fixedly connected with seal receptacle, spiral casing pressure
Seal receptacle outer wall is placed in, it is pressed between seal receptacle inwall and axle sleeve outer wall to have the oil-containing sliding shaft sleeve, several being laterally arranged in order
Packing, sealing shroud, sealing ring, sealing ring end face mutually press with end cover, are provided with sealing ring dust-proof with helical axis cooperation
Circle.
Coordinate between described axle sleeve and helical axis for interference fits or small―gap suture, and use holding screw axially position.
Described sealing shroud, the material of sealing ring are polytetrafluoroethylene (PTFE), form axial seal.
Described packing has three, and sectional dimension is 10 × 10mm, forms first of sealing.
Advantageous effects of the present utility model are as follows：
1st, solves the problems, such as helical axis abrasion, axle sleeve coordinates with helical axis interference fits or small―gap suture, and main function prevents
Helical axis spindle nose surface abrasion；
2nd, helical axis both ends away from it is big cause assembling when two axial ends concentricity it is larger, the problem of accelerating both ends ring wear.
Axle both ends dress oil-containing sliding bearing is the installation fulcrum of closed chamber front end, prevents indoor sealing ring from damaging；
3rd, material leakage problem, packing are first of sealing, and sealing shroud opens axial seal effect；Sealing shroud opens radial seal
Effect；End cover opens spacing left and right, and dust ring opens sealing and dustproof effect；Spherical outside surface is usherd to seat, and self-aligning bearing opens carrying, aligning fills
With effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of conveying worm Anti-powder-leakage associated sealing arrangement for bearings, include the axle being installed on helical axis 1
Set 3, self-aligning bearing 10 of usheing to seat is gripped with end cover 8 between axle sleeve 3 and self-aligning bearing 10 of usheing to seat, end cover 8 is fixedly connected
Have seal receptacle 11, screw-casing 2 is pressed on the outer wall of seal receptacle 11, between the inwall of seal receptacle 11 and the outer wall of axle sleeve 3 it is pressed have laterally according to
Oil-containing sliding shaft sleeve 4, several packings 5, sealing shroud 6, the sealing ring 7 of secondary arrangement, the end face of sealing ring 7 press with the phase of end cover 8,
The dust ring coordinated with helical axis 1 is provided with sealing ring 7.Coordinate between axle sleeve 3 and helical axis 1 for interference fits or small―gap suture,
And use the axially position of holding screw 12.Sealing shroud 6, the material of sealing ring 7 are polytetrafluoroethylene (PTFE), form axial seal.Packing
There are three, and sectional dimension is 10 × 10mm, forms first of sealing.
Oil-containing sliding shaft sleeve is used to prevent axle sleeve from wearing, and dust ring is used to prevent dust from revealing, and self-aligning bearing of usheing to seat is used for
Helical axis end fixed pivot.
The utility model is for helical feed powdery or small microparticle material material leakage and damage bearing situation.Pacify in outside
Fill spherical outside surface and provoke bearing, be i.e. bearing is installed as open type assembling.Whole device includes seal receptacle and spherical outside surface and usherd to seat self-aligning bearing,
Wherein contain axle sleeve in seal receptacle, contain sliding shaft sleeve, packing, sealing shroud, sealing ring, end cover, dust ring, holding screw
Deng.Material from leakage in anti-helix tube, also can anti-extraneous nuisance contaminated food products to food service industry.
