Technical field
The utility model relates to reducer technology field more particularly to a kind of underground scratch board conveyor speed reducer sealing knots
Structure.
Background technique
Underground coal mine bad environments, underground scratch board conveyor and its speed reducer are equally run under severe operating condition, generally
Common output end of reducer is the sealing means of outside framework oil seal or single float grease seal, although the work of sealing can be played
With, but since downhole powder dust impurity is more, running environment is severe, now Packed persistence reduction is caused, causes often to go out
The occurrence of existing oil leak, however underground narrow space, inconvenient maintenance, and frequently maintenance also reduces production efficiency.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of underground scratch board conveyor speed reducer sealing knot
Structure.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of underground scratch board conveyor speed reducer sealing structure, including float grease seal, the end of speed reducer output shaft are fixed
There is end cap, the end cap of speed reducer output shaft is embedded in the end cap slot at the top of decelerator shell, the end cap side of speed reducer output shaft
Edge is installed with rubber seal, and rubber seal is equipped with oil groove, the top of rubber seal away from the side of speed reducer output shaft
It is bonded with decelerator shell and between bottom and decelerator shell there are gap, decelerator shell is interior to be equipped with grease lubrication oil circuit, rouge
The output end of lubricant passage way is connected to oil groove,
Annular recess one, speed reducer output are coaxially provided at the top of decelerator shell with the speed reducer output shaft of scratch board conveyor
The position that the end cap bottom of axis corresponds to annular recess one is equipped with annular recess two, and float grease seal includes by annular recess one and ring-type
The floating seat that groove two serves as is equipped with sealing ring in two floating seats and is equipped between floating seat and corresponding sealing ring soft
Sealing ring, two sealing rings contact with each other and contact surface is equipped with oil film.
Preferably, soft sealing ring uses section for circular hydrogenated nitrile-butadiene rubber O-ring seals.
Preferably, the section of oil groove is V-arrangement, is bonded at the top of oil groove with decelerator shell and bottom and decelerator shell divide
From.
Preferably, rubber seal uses V-Ring type sealing ring.
The beneficial effects of the utility model are: the utility model can effectively completely cut off the impurity such as dust and float grease seal,
The service life of float grease seal is extended, sealing effect is ensure that, reduces frequency of maintenance to improve production efficiency, simultaneously
Grease lubrication oil circuit is to rubber seal sufficient lubrication, to reduce friction, reduce output temperature.
Detailed description of the invention
Fig. 1 is the partial sectional view of speed reducer；
Fig. 2 is the enlarged drawing in Fig. 1 at A；
In figure: 1- float grease seal；2- speed reducer output shaft；3- decelerator shell；4- rubber seal；5- oil groove；6- rouge
Lubricant passage way；11- floating seat；12- sealing ring；The soft sealing ring of 13-；
It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown, a kind of underground scratch board conveyor speed reducer sealing structure, including float grease seal 1, speed reducer output shaft 2
End be installed with end cap, the end cap of speed reducer output shaft 2 is embedded in the end cap slot at 3 top of decelerator shell, and speed reducer is defeated
The end cap edge of shaft 2 is installed with rubber seal 4, and rubber seal 4 is equipped with oil groove 5 away from the side of speed reducer output shaft 2,
The top of rubber seal 4 is bonded with decelerator shell 3 and there are gap, decelerator shells 3 between bottom and decelerator shell 3
Interior to be equipped with grease lubrication oil circuit 6, the output end of grease lubrication oil circuit 6 is connected to oil groove 5,
3 top of decelerator shell and the speed reducer output shaft 2 of scratch board conveyor are coaxially provided with annular recess one, and speed reducer is defeated
The position that the end cap bottom of shaft 2 corresponds to annular recess one is equipped with annular recess two, and float grease seal 1 includes by one He of annular recess
The floating seat 11 that annular recess two serves as is equipped with sealing ring 12 in two floating seats 11 and floating seat 11 and corresponding sealing ring 12
Between be equipped with soft sealing ring 13, two sealing rings 12 contact with each other and contact surface is equipped with oil film.
Preferably, soft sealing ring 13 uses section for circular hydrogenated nitrile-butadiene rubber O-ring seals.
Preferably, the section of oil groove 5 is V-arrangement, and the top of oil groove 5 is bonded with decelerator shell 3 and bottom and decelerator shell 3
Separation.
Preferably, rubber seal 4 uses V-Ring type sealing ring.
When scratch board conveyor operates, the end cap of speed reducer output shaft 2 presses soft sealing ring 13 for by axial pressure
Tightly in the sealing ring 12 on top, while soft sealing ring 13 seals by the stiction of two sides make the sealing ring 12 on top with
