Abstract
The invention discloses a kind of serial elevator lower sprocket bearing seal structures of NE, belong to technical field of mechanical, its structure includes bearing, watt seat and end cap, sealing ring is provided with watt between seat and elevator housing, described watt is provided with a labyrinth end covers between seat and sealing ring, described labyrinth end covers include the annular projection bar concentric with pipe is distributed with the pipe and disk linked together, disk, and watt seat is provided with the annular recess being engaged with the raised item.The present invention is provided with end cover, prevents material, dust from entering in bearing so that the useful life of bearing is greatly prolonged.
Description
Technical field
The present invention relates to a kind of bearing seal structure, specifically a kind of serial elevator lower sprocket bearing seal knots of NE
Structure, belongs to technical field of mechanical.
Background technology
At present, the chain of the serial elevators of NE is plate chain, and when only weight pushes down lower sprocket, elevator chain is in lower chain
It could be operated in wheel gear.Because chain pitch is big, elevator lower sprocket will be moved frequently, because major part is granular material,
Very big difficulty is brought to bearing seal.
The serial elevator lower sprocket bearing seal structures of existing NE are as shown in Fig. 1 of Figure of description, and its structure includes
Bearing 5, watt seat 4 and end cap 6, bearing 5 are located at the end of lower sprocket axle 1, and watt seat 4 covers bearing 5, and end cap 6 is fixed with watt seat 4
Connection, is provided with sealing ring 3 between watt seat 4 and elevator housing 2.It is high due to going out to grind cement temperatures in said structure, lift casing
Slide plate movement on body 2 is frequent, and bearing 5 is easily damaged.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of serial elevator lower sprocket bearing seal structures of NE,
The sealing structure prevents material, dust from entering in bearing so that the useful life of bearing is greatly prolonged.
The technical scheme adopted by the invention to solve the technical problem is that：A kind of serial elevator lower sprocket bearing seals of NE
Structure, including bearing, watt seat and end cap, bearing are located at the end of lower sprocket axle, and a watt seat covers bearing, and end cap is fixed with a watt seat
Connection, is provided with sealing ring between watt seat and elevator housing, described watt is provided with a labyrinth end covers between seat and sealing ring, described
Labyrinth end covers include the pipe and disk that link together, and the pipe is fixed and is nested with lower sprocket axle, the disk with watt
Seat is engaged；The annular projection bar concentric with pipe is distributed with disk, watt seat is provided with the ring being engaged with the raised item
Shape groove；Sealing ring is nested with the outer surface of side of circular pipe wall and positioned between disk and elevator housing.
It is preferred that, the raised item on the disk is provided with three.
The beneficial effects of the invention are as follows：Mazy end cover is together added, it is reinforced on lower sprocket axle, makes it
Operated simultaneously with lower sprocket axle, mazy end cover is provided with raised item on disk, watt seat being matched therewith is provided with
Groove, labyrinth end covers is buckled on corresponding watt seat labyrinth, prevents material, dust from entering in bearing, such validity period
It will extend, none damage in 2~3 years in actual experiment.
Brief description of the drawings
Fig. 1 is the structural representation of the serial elevator lower sprocket bearing seals of current NE；
Fig. 2 is the structural representation of the embodiment of the present invention；
Fig. 3 is the dimensional structure diagram of labyrinth end covers in the embodiment of the present invention；
In figure：1 lower sprocket axle, 2 elevator housings, 3 sealing rings, 4 watts of seats, 5 bearings, 6 end caps, 7 labyrinth end covers, 71 circles
Pipe, 72 disks.
Embodiment
With reference to Figure of description and specific embodiment, the invention will be further described：
As shown in Figure 2 and Figure 3.A kind of serial elevator lower sprocket bearing seal structures of NE, including bearing 5, watt seat 4 and end
Lid 6, bearing 5 is located at the end of lower sprocket axle 1, and watt seat 4 covers bearing 5, and end cap 6 is fixedly connected with watt seat 4, and watt seat 4 is with carrying
Sealing ring 3 is provided between liter casing body 2, a labyrinth end covers 7, described labyrinth end covers are provided between described watt of seat 4 and sealing ring 3
7 include the pipes 71 and disk 72 that link together, and the pipe 71 is fixed and is nested with lower sprocket axle 1, the disk 72 with
Watt seat 4 is engaged；The annular projection bar concentric with pipe 71 is distributed with disk 72, watt seat 4 is provided with and the raised item phase
The annular recess of cooperation；Sealing ring 3 be nested with the outer surface of the side wall of pipe 71 and positioned at disk 72 and elevator housing 2 it
Between.
In view of sealing effectiveness and processing cost, the raised item on the disk 72 is provided with three.
The present invention has added mazy end cover together on the basis of current bearing seal structure, and it is reinforced under
On sprocket shaft 1, it is set to be operated simultaneously with lower sprocket axle 1, mazy end cover is provided with raised item on disk 72, with its phase
Watt seat 4 coordinated is provided with groove, labyrinth end covers 7 is buckled on corresponding watt seat labyrinth, prevents material, dust from entering
In bearing 5, such validity period will extend, none damage in 2~3 years in actual experiment.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not the whole embodiments of the present invention, not to limit
The system present invention, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in
Within protection scope of the present invention.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art, in order to prominent
Go out the innovative characteristicses of the present invention, will not be repeated here.
