Embodiment
The utility model embodiment provides a kind of non-contact type high speed shaft seal mechanism, simple in construction, easy for installation, and anti-
Corrosion, sealing protection can not only be carried out to bearing, avoid bearing oil leak from breaking ring slurry, and can solve contact type sealing structure appearance
It is also easy to produce problem of temperature rise.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 2 to Fig. 3, a kind of particular technique side of non-contact type high speed shaft seal mechanism of the utility model embodiment
Case is：
Non-contact type sealing mechanism includes high speed shaft 3, bearing block 1, bearing 2, fisrt feature part 6, second feature part 7, the
Three features 8 and batch mixing pan 9, wherein the concrete shape of above-mentioned each part, structure and annexation are as follows：
High speed shaft 3, high speed shaft 3 are arranged on inside bearing block 1 by bearing 2.
Fisrt feature part 6, the one side of fisrt feature part 6 is located at the lower section of bearing 2 and compresses bearing 2, and fisrt feature part 6
It is fixed on bearing block 1, fisrt feature part 6 is fixed on bearing block 1 using mode connects for screw.
Third feature part 8, third feature part 8 are fixed on fisrt feature part 6, and third feature part 8 is consolidated using mode connects for screw
It is scheduled on fisrt feature part 6.
Second feature part 7, second feature part 7 are located in the hollow cavity that fisrt feature part 6 and third feature part 8 surround,
And second feature part 7 is connected with high speed shaft 3, as second feature part 7 is fixed on high speed shaft 3 and therewith by holding screw
Rotate together.Be provided with sealing ring at the endoporus that second feature part 7 and high speed shaft 3 coordinate, prevent lubricating oil by high speed shaft 3 and
Space between second feature part 7 enters among slurry.
It should be noted that fisrt feature part 6 and second feature part 7 are a pair of dresses for being not in contact with each other and being mutually embedded in
Put, as fisrt feature part 6 is provided with tongue and groove, second feature part 7 is embedded in tongue and groove and has gap between tongue and groove, when
When there are several tongue and grooves, the labyrinth channel of S-shaped can be formed, is sealed by labyrinth channel, and bearing 2 is from cover
Sealing type bearings, the lubricating oil of reduction Bearing inner as far as possible is thrown away and foreign matter enters bearing.Due to long-time at a high speed
Operation, still suffer from minimal amount lubricating oil and be thrown out of, a small amount of lubricating oil being now thrown out of can by more than labyrinth channel it
Between gap enter third feature part 8 cavity at store.In addition, between what is formed between fisrt feature part 6 and second feature part 7 has
The labyrinth channel of gap can effectively prevent external dust impurity etc. from entering bearing 2.
Third feature part 8 is a pair of devices for being not in contact with each other and being mutually embedded in second feature part 7, such as third feature part
8 are provided with tongue and groove, and second feature part 7 is embedded in tongue and groove and has gap between tongue and groove, when there is several tongue and grooves
When, the labyrinth channel of S-shaped can be formed, is sealed by labyrinth channel, the labyrinth channel both effectively prevented foreign matter from entering
Bearing 2, a small amount of lubricating oil that can also prevent to flow at the cavity of third feature part 8 are thrown away at slurry.Due to second feature part 7
Forming first layer with fisrt feature part 6 has the labyrinth channel in gap, and the bottom of second feature part 7 forms second with third feature part 8
Layer has the labyrinth channel in gap, and two layers of labyrinth channel is with the use of both preventing lubricating oil from throwing away outside, prevented also from external dust
Impurity enters bearing.
Batch mixing pan 9, batch mixing pan 9 is located at below third feature part 8 and is connected with high speed shaft 3, as batch mixing pan 9 passes through
Holding screw is fixed on high speed shaft 3 to be rotated together therewith.When batch mixing pan 9 is fixed on high speed shaft 3 by holding screw, the
Three features 8 and batch mixing pan 9 are setting up and down and have gap between the two, and gap is about 1mm between both.Batch mixing pan 9 is
Turbine type blade construction,, can be by the warm of output at bearing 2 toward external exhaust gas when with 3 one superhigh speed rotate counterclockwise of high speed shaft
Amount takes outside out of, plays radiating and cooling effect.Batch mixing pan 9, which rotates at a high speed, simultaneously makes gas be blown outward, effectively outside prevention
Powder impurity enters in labyrinth channel and bearing 2.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those within the art that：It still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and model of various embodiments of the utility model technical scheme
Enclose.
