Description
Technical field
The utility model relates to a kind of sealing ring, it is close to belong to Power generator fan for specifically a kind of ladder V-shaped ring
Seal structure technical field.
Background technique
It is well known that the stator of generator, rotor, bearing (ball) cover and bearing are different modular unit.It generates electricity in assembly
When machine, son is first set, then rotor is protruded into together with fan and axis from driving end, finally installs bearing (ball) cover and bearing.Bearing
Major function first is that supporting mechanical rotary body (rotor), only bearing (ball) cover and bearing assembles simultaneously, and rotor could be supported
Get up.
When fan running, due to internal and external pressure difference, the lubricating oil in bearing can be sucked inside machine by fan, it is necessary to be arranged
Sealing structure is isolated, and cannot have interference with bearing and fan.Marine generator contracts as far as possible since space is limited
Small length, improving space utilization rate is the task of top priority.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, so that a kind of ladder V-shaped ring is provided, it being capable of shape
At effective sealing between bearing (ball) cover and fan, avoid bearing oil by inside fan sucking machine, seal ring structure is tight
Reason is gathered together, space utilization rate is improved.
According to technical solution provided by the utility model, a kind of ladder V-shaped ring include outer ring ring body, intermediate ring body and
Inner ring ring body, it is characterized in that: intermediate ring body, the seal face side weldering of intermediate ring body are welded in the seal face side of outer ring ring body
Inner ring ring body is connect, outer ring ring body, intermediate ring body and inner ring ring body are arranged concentrically；The race diameter of outer ring ring body is greater than intermediate ring body
Race diameter, the race diameter of intermediate ring body is greater than the race diameter of inner ring ring body, so that outer ring ring body, intermediate ring body
Stair-stepping seal face is formed between inner ring ring body.
Further, ring body center in outer ring is equipped with outer ring annular distance, and intermediate ring body center is equipped with intermediate annular distance, in inner ring ring body
The heart is equipped with inner ring annular distance, and the diameter of outer ring annular distance is greater than the diameter of intermediate annular distance, and the diameter of intermediate annular distance is greater than inner ring annular distance
Diameter.
Further, it is equipped with multiple sealing ring annular grooves in inner ring annular distance, is embedded in rubber seal in each sealing ring annular groove.
Further, the installation end face side of outer ring ring body is equipped with installation base.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, and sealing ring is capable of forming effective close between bearing (ball) cover and fan
Envelope avoids bearing oil by inside fan sucking machine, and seal ring structure compact and reasonable improves space utilization rate；Sealing
Ring plays the role of bearing.
Detailed description of the invention
Fig. 1 is the utility model main view.
Fig. 2 is A-A cross-sectional view in Fig. 1.
Description of symbols: ring body, 3- inner ring ring body, 4- sealing ring annular groove, 5- rubber seal among the outer ring 1- ring body, 2-
Annular distance, 8- inner ring annular distance, 9- installation base among circle, the outer ring 6- annular distance, 7-.
Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1 and 2, the utility model mainly includes outer ring ring body 1, intermediate ring body 2 and inner ring ring body 3, outer ring ring body
The 1 intermediate ring body 2 of seal face side welding, the seal face side welding inner ring ring body 3 of intermediate ring body 2, outer ring ring body 1,
Intermediate ring body 2 and inner ring ring body 3 are arranged concentrically.
The race diameter of outer ring ring body 1 is greater than the race diameter of intermediate ring body 2, and the race diameter of intermediate ring body 2 is greater than interior
The race diameter of ring body 3, so that forming stair-stepping sealing between outer ring ring body 1, intermediate ring body 2 and inner ring ring body 3
End face.
Ring body 1 center in outer ring is equipped with outer ring annular distance 6, and intermediate 2 center of ring body is equipped with intermediate annular distance 7, and 3 center of inner ring ring body is set
There is inner ring annular distance 8, the diameter of outer ring annular distance 6 is greater than the diameter of intermediate annular distance 7, and the diameter of intermediate annular distance 7 is greater than inner ring annular distance 8
Diameter.
It is equipped with multiple sealing ring annular grooves 4 in the inner ring annular distance 8, is embedded in rubber seal 5 in each sealing ring annular groove 4,
Rubber seal 5 contacts to form sealing with axis.
The installation end face side of the outer ring ring body 1 is equipped with installation base 9, and the utility model is installed by installation base 9
On bearing (ball) cover.
The working principle of the utility model is: the sealing ring of the utility model is mounted on bearing (ball) cover and fan when in use
Between, sealing ring is done into a ladder, the interference with other elements can be cleverly avoided, save space, effectively shortens machine
Device length, rubber seal have good sealing function, and air can be blocked to enter in machine outside machine, prevent the oil of bearing
It is sucked by fan.In addition, installation axle brought forward, this sealing ring can play temporary supporting role after installing rotor.
