Abstract
A kind of combined sealing device of speed reducer is related to a kind of combined sealing device of speed reducer, belongs to transmission machinery field.Including rotating ring (4), stationary ring, bearing air cover, outside framework oil seal (5), the bearing air cover forms cavity, portion, rotating ring (4) are mounted on rotary shaft (1) in the cavity for rotating ring (4), stationary ring setting, and the outside framework oil seal (5) is arranged between bearing air cover and rotating ring (4).The utility model can quickly carry out disassembling, assembling and replacing sealing, and everyday devices is facilitated to safeguard, reduce worker's labor intensity, sealing effect.The oil product that reduction is generated by sealing leak consumes and other impurities enter oil pollution caused by box house, and the expense of the manual cleaning saved realizes the clear production of producing line.
Description
Technical field
The utility model relates to a kind of combined sealing device of speed reducer, belong to mechanical transmission fields.
Background technique
In metallurgy, Steel-rolling Industry, speed reducer has extremely important effect.But speed reducer Leakage annoyings always
Production, not only causes the waste of physical resources, but also polluted environment.It is at rotary shaft and the cooperation of bearing air cover sealing element
The main oil leak position of speed reducer.It is primarily due to high speed rotation, long using the time, in addition external environment is more severe.Once grey
Dirt, sundries enter box house, will pollute to lubricating system, and accelerate the abrasion of sealing ring, so as to shorten speed reducer
Service life.
The sealing device of speed reducer can be divided into contact and contactless two types.Conventional contact sealing has structure
Simply, the advantages that leakage rate is smaller, however be affected by rotating shaft surface roughness, and the lip of oil sealing and axis surface
Contact pressure is bigger, and speed of related movement is higher, then by rubbing, caused temperature rise is faster, and temperature is also higher, wears lip
And burn, the seal failure of oil sealing is caused, the service life of oil sealing is shortened.Contactless advantage is it not by circumference speed
The influence of degree and temperature improves the service life of speed reducer without energy loss.However non-contacting seal by rotating ring with
Gap between stationary ring carries out oil sealing, has the shortcomings that leakage rate is larger.
According in the operating conditions of the advantage and disadvantage of both the above pattern sealing and live speed reducer, running speed and cabinet
Portion's pressure size and cost and benefit consider that urgent need, which designs one kind, can gather contact seal and non-contacting seal advantage
Sealer with assembled, realize sealing to speed reducer.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of combined sealing device of speed reducer, realize to speed reducer
Sealing, reduce the leakage of speed reducer lubricating oil, prevent environmental pollution, guarantee normal production.
Solve the technical solution of above-mentioned technical problem are as follows:
A kind of combined sealing device of speed reducer, including rotating ring, stationary ring, bearing air cover, outside framework oil seal, the bearing air cover group
At cavity, portion, rotating ring are installed on the rotary shaft in the cavity for rotating ring, stationary ring setting, and the outside framework oil seal is arranged in bearing air cover
Between rotating ring.
Combined sealing device of speed reducer as described above, the bearing air cover is by transparent cover structure under transparent cover on bearing and bearing
At being bolted to connection.
Combined sealing device of speed reducer as described above, the stationary ring are made of top stationary ring and lower part stationary ring, pass through weldering
The mode connect is separately fixed on bearing under transparent cover and bearing in transparent cover.
Combined sealing device of speed reducer as described above is provided with labyrinth ring on the top stationary ring, lower part stationary ring.
Drain pan and oil leak hole are arranged on the lower part stationary ring for combined sealing device of speed reducer as described above.
The utility model has the following beneficial effects:
The utility model can quickly carry out disassembling, assembling and replacing sealing, and everyday devices is facilitated to safeguard, reduce worker's labor intensity, close
Seal effect.The oil product that reduction is generated by sealing leak consumes and other impurities enter oil pollution caused by box house, saves
Manual cleaning expense, realize the clear production of producing line.
Detailed description of the invention
Fig. 1 is utility model diagram；
Fig. 2 is the utility model side view；
In the figure, it is marked as transparent cover 3 on rotary shaft 1, bearing 2, bearing, rotating ring 4, outside framework oil seal 5, oil leak hole 6, drain pan 7,
Transparent cover 8, top stationary ring 9, lower part stationary ring 10 under bearing.
Specific embodiment
The utility model is described in further details with attached drawing combined with specific embodiments below.
As shown in the picture, a kind of speed reducer novel combined sealing device of the utility model, including transparent cover on rotating ring 4, bearing
3, transparent cover 8, outside framework oil seal 5 under bearing；Rotating ring 4 is fixed in rotary shaft 1 by interference fit, and rotary shaft 1 is followed to rotate；Top
Stationary ring 9, lower part stationary ring 10 and transparent cover 8 under transparent cover 3, bearing on bearing are fixed as one by welding manner respectively, and to axis
It holds and is machined with drain pan 7, oil leak hole 6 on the lower part stationary ring of lower transparent cover 8；Transparent cover 8 forms under transparent cover 3, bearing on rotating ring 4 and bearing
First of sealing --- the non-contacting seal of the combination sealing；In rotary shaft 1 and bearing under transparent cover 3, bearing between transparent cover 8
Design has outside framework oil seal 5, and transparent cover 8, outside framework oil seal 5 form combination sealing second sealing under transparent cover 3, bearing on bearing ---
Contact seal；The lubricating oil taken out of by high-speed rotation shaft 1 passes through non-contact seals, i.e., transparent cover under transparent cover 3, bearing on bearing
Enter drain pan 7, oil leak hole 6, reflux such as box house inside labyrinth ring between 8 and rotating ring 4；The lip of outside framework oil seal 5 by
Box house pressure influence is opened, and the lubricating oil of first of sealing is crossed in block, enables its flow into transparent cover 3, axis on rotating ring 4 and bearing
Inside the labyrinth ring for holding lower transparent cover 8, and then cabinet is passed back by drain pan 7, oil leak hole 6.
