Abstract
The utility model relates to a dicyclo labyrinth seal structure for gear box, dicyclo labyrinth seal structure pass through approximately and sealing between the axis body on being used for the gear box, the movive seal ring on the axis body is established to the static seal ring that includes and cover outer end facial features rigid coupling with thoroughlying and fixed cover, and cross -section that the static seal encircled is first flute profile, and cross -section that the movive seal encircled is the second flute profile, and notches first, two flute profiles arrange in opposite directions, and in a cell wall of first flute profile extended to the second flute profile, a cell wall of second flute profile extended to in the first flute profile. The utility model provides a labyrinth seal structure mainly comprises two sealing rings, and the movive seal ring is installed epaxial, and the during operation rotates along with the axle, static seal ring is installed and is being covered thoroughly, the during operation with pass through the lid and keep static. The gear box during operation, two sealing rings rotate relatively, form the peak, the anxious maze passageway that turns round, and lubricating oil is during through this maze passageway, locally grinds that to hinder the effect big, sealed effectual, leaves the clearance between two sealing rings, does not have wearing and tearing, does not need the periodic replacement.
Description
Technical field
The utility model relates to field of sealing technology, is specifically related to a kind of dicyclo labyrinth seal structure for gear-box.
Background technique
Existing gearbox seals technology has soft packing seal, mechanical seal, skeleton oil seal and labyrinth seal etc.All there are wearing and tearing in wherein soft packing seal, mechanical seal, outside framework oil seal, needs periodic replacement, and existing common labyrinth seal structure generally takes up room comparatively large, and sealing effect is general, often occurs mist of oil, gets rid of wet goods phenomenon.
Model utility content
The purpose of this utility model is just to provide a kind of dicyclo labyrinth seal structure for gear-box, and it can effectively solve the problem, and can realize good gearbox seals in less space.
For achieving the above object, the utility model have employed following technological scheme:
A kind of dicyclo labyrinth seal structure for gear-box, it is characterized in that: the sealing of dicyclo labyrinth seal structure on gear-box between transparent cover and axis body, comprise the rotary packing ring be located at the stationary seal ring of transparent cover exterior edge face Joint and fixed cover on axis body, the cross section of stationary seal ring is the first flute profile, the cross section of rotary packing ring is the second flute profile, the notch of first and second flute profile is arranged in opposite directions, a cell wall of the first flute profile extends in the second flute profile, and a cell wall of the second flute profile extends in the first flute profile.
Concrete scheme is: the notch of first and second flute profile is closing in shape.First flute profile is U-shaped, first flute profile carries out turnover formation flanging near the cell wall of axis body to the side away from axis body, second flute profile is that angle is arranged near the cell wall of axis body side and the heart yearn of axis body, and angle points to static sealing ring side, first flute profile extends in the second flute profile away from the cell wall of axis body side, and the cell wall of the second flute profile near axis body side extends in the first flute profile.The groove width of the second flute profile first increases gradually along groove depth direction, after reduce gradually.
The dicyclo labyrinth seal structure provided in technique scheme:
1, in less space, multiple tracks labyrinth seal is realized;
2, two seal rings form peak, turn round anxious labyrinth channel, good sealing effect;
3, two seal ring thickness is thin, quality light, saves material;
4, do not need to regularly replace Sealing.
Accompanying drawing explanation
Fig. 1 is the utility model assembling schematic diagram;
Fig. 2 is the A place enlarged diagram in Fig. 1;
Fig. 3 is the structural representation of stationary seal ring;
Fig. 4 is the structural representation of rotary packing ring.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete mode of executions of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technological scheme that the utility model is taked is as Fig. 1, shown in 2, a kind of dicyclo labyrinth seal structure for gear-box, the sealing of dicyclo labyrinth seal structure on gear-box between transparent cover 12 and axis body 11, comprise the rotary packing ring 22 be located at the stationary seal ring of transparent cover 12 exterior edge face Joint and fixed cover on axis body 11, the cross section of stationary seal ring 21 is the first flute profile 211, the cross section of rotary packing ring 22 is the second flute profile 221, first, the notch of two flute profiles is arranged in opposite directions, a cell wall of the first flute profile 211 extends in the second flute profile 221, a cell wall of the second flute profile 221 extends in the first flute profile 211.Axis body 11 is output shafts of gear-box, and transparent cover 12 pairs of axis bodies 11 carry out axially locating and compression, and coordinate stationary seal ring and rotary packing ring to seal.The labyrinth seal structure that the utility model provides forms primarily of two seal rings, and rotary packing ring 22 is arranged on axle, rotates during work with axle; Stationary seal ring 21 is arranged in transparent cover 12, during work and transparent cover 12 keep static.During gear-box work, two seal rings relatively rotate, and form peak, turn round anxious labyrinth channel, and when lubricant oil is by this labyrinth channel, local mill inhibition effect is large, and good sealing effect, leaves gap between two seal rings, without wearing and tearing, does not need periodic replacement.
Concrete scheme is, as shown in Figure 2,3, 4, the notch of first and second flute profile is closing in shape.First flute profile 211 is U-shaped, first flute profile 211 carries out turnover formation flanging 212 near the cell wall of axis body 11 to the side away from axis body 11, second flute profile 221 is that angle is arranged near the cell wall of axis body 11 side and the heart yearn of axis body 11, and angle points to static sealing ring side, first flute profile 211 extends in the second flute profile 221 away from the cell wall of axis body 11 side, and the cell wall of the second flute profile 221 near axis body 11 side extends in the first flute profile 211.The groove width of the second flute profile 221 first increases gradually along groove depth direction, after reduce gradually.By the enforcement of above-mentioned concrete mode, its sealing effect is better.
Above-mentioned labyrinth seal structure may be used for the sealing of the high speed shaft of wind turbine gearbox, and rotary packing ring 22 is arranged on high speed shaft, rotates during work with high speed shaft; Stationary seal ring 21 is arranged in transparent cover 12, during work and transparent cover 12 keep static, when wind turbine gearbox works, two seal rings form labyrinth seals, through actual tests checking, have good sealing effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
