Description

Novel gear cover sealing labyrinth structure

Technical Field

The utility model relates to a novel gear cover seals maze, mechano-electronic structure field.

Background

The gear cover is a rain-proof protection structure commonly used in the antenna pedestal. The gear cover is usually a thin-walled housing with flanges covering the gear, and it can be made by splicing or be an integral body. Usually, one end of the gear cover is fixed on the antenna pedestal base, and a circle of relative movement gap is formed between the other end of the gear cover and the rotary table, or one end of the gear cover is fixed on the rotary table, and a circle of relative movement gap is formed between the other end of the gear cover and the antenna pedestal base. The gap of the relative movement needs to be sealed, and the common method is to seal a sealing ring between the relatively moving components or form a rain-eaves type structure between the relatively moving components. The seal ring added between the relatively moving components can be worn after long-time movement, so that the problem of unreliable sealing is caused. Rain eaves formula rain-proof protection architecture, when strong wind and rainwater angle are more, can appear taking the rainwater into the problem in the gear cover.

SUMMERY OF THE UTILITY MODEL

To above problem, the utility model provides a have simple structure, with low costs, sealed reliable, install and remove convenient novel sealed maze of gear cover, the utility model discloses can solve the rain-proof problem in gap between position gear wheel and the gear cover.

In order to solve the above problem, the utility model adopts the following technical scheme: a novel gear cover seal labyrinth structure is characterized by comprising a gear cover and a labyrinth cover plate; the gear cover is fixed with the antenna pedestal base, the labyrinth cover plate is fixed with the azimuth large gear, labyrinth seals are adopted between the labyrinth cover plate and the gear cover, and the labyrinth cover plate and the gear cover are convenient to mount and dismount.

The gear cover is the lower part of the sealed labyrinth, and a concentric labyrinth ring II and a labyrinth groove II are arranged on the gear cover; the bottom of the labyrinth groove II is gradually increased from outside to inside, the innermost labyrinth ring II is a non-notched labyrinth ring to prevent rainwater from flowing into the gear cover, and staggered notches are formed in other labyrinth rings II; the bottom of the labyrinth groove II is gradually increased from outside to inside, so that rainwater on the gear cover can be prevented from flowing into the labyrinth; the labyrinth ring gap can make the water rushing into the labyrinth flow out of the labyrinth.

The labyrinth cover plate is the upper part of the sealed labyrinth, and a concentric labyrinth ring I and a labyrinth groove I are arranged on the labyrinth cover plate; the height of labyrinth circle I is by outer diminishing gradually inwards, and the height of every circle is less than the height of corresponding labyrinth groove II, and the width of labyrinth circle I is less than the width of corresponding labyrinth groove II, and the width of labyrinth groove I is greater than the width of corresponding labyrinth circle II, and the design of this structure can be further for rivers provide the passageway to avoid producing ponding.

The labyrinth cover plate and the azimuth gearwheel are sealed by a sealing ring.

Compared with the prior art, the utility model, following beneficial effect has: the utility model has the advantages of simple structure, with low costs, sealed reliable, install and remove the convenience.

Detailed Description

The present invention will be described in further detail below.

As shown in fig. 1 to 5, the utility model provides a novel gear cover seal labyrinth structure, which comprises a gear cover 1 and a labyrinth cover plate 2; the gear cover 1 is fixed with the antenna pedestal base 7, the labyrinth cover plate 2 is fixed with the azimuth big gear 5, labyrinth sealing is adopted between the labyrinth cover plate 2 and the gear cover 1, and the labyrinth cover plate 2 and the azimuth big gear 5 are sealed by a sealing ring 6.

As shown in fig. 2 and 3, the gear cover 1 is a lower part of the seal labyrinth, and the gear cover 1 is provided with a concentric labyrinth ring ii 8 and a labyrinth groove ii 9. The bottom of the labyrinth groove II 9 is gradually increased from outside to inside, the innermost labyrinth ring II 8 is a non-notched labyrinth ring, and staggered notches 10 are formed in other labyrinth rings II 8;

as shown in fig. 4 and 5, the labyrinth cover 2 is an upper part of the seal labyrinth, and a concentric labyrinth ring i 3 and a labyrinth groove i 4 are provided on the labyrinth cover 2. The height of the labyrinth ring I3 is gradually reduced from outside to inside, the height of each ring is smaller than the height of the corresponding labyrinth groove II 9, the width of the labyrinth ring I3 is smaller than the width of the corresponding labyrinth groove II 9, and the width of the labyrinth groove I4 is larger than the width of the corresponding labyrinth ring II 8.
