Abstract

The utility model belongs to the technical field of the gear equipment technique and specifically relates to a gear box of making an uproar falls in just installation type, including the gear box body, gear box body lateral wall is equipped with and falls the board of making an uproar, it includes the casing to fall the board of making an uproar, the amortization groove has been seted up in the casing, and amortization groove one side is located and is equipped with the amortization cotton in the casing. The utility model discloses a gear box of making an uproar falls in just installing type sets gradually the amortization groove and packs the amortization cotton in falling the inboard of making an uproar, then accomplishes the back at the inside equipment of gear box body, falls the board inlay card with it and connects on gear box body lateral wall, and then has realized the absorption and the weakening to this internal noise of gear box, the effectual produced noise of gear box that has reduced.

Description

Just, gear box of making an uproar falls in installation type

Technical Field

The utility model belongs to the technical field of gear equipment technique and specifically relates to a gear box of making an uproar falls in just installation type.

Background

The gear box is widely applied to wind generating sets, is often used in the wind generating sets and is an important mechanical component, and the gear box mainly has the function of transmitting power generated by a wind wheel under the action of wind power to a generator and enabling the generator to obtain corresponding rotating speed. The rotating speed of the wind wheel is usually very low, which is far from the rotating speed required by the power generation of the generator, and the rotating speed is realized by the speed increasing action of the gear pair of the gear box, so the gear box is also called as the speed increasing box, the internal gear meshing transmission can generate larger sound in the running process of the gear box, and the noise can generate radiation and generate the amplification action through the shell, so the influence on the external noise is larger.

SUMMERY OF THE UTILITY MODEL

In order to overcome the big not enough of current gear box noise, the utility model provides a just, gear box of making an uproar falls in installation type sets gradually the amortization groove and packs the amortization cotton in falling the inboard of making an uproar, then accomplishes the back at gear box body internal portion, falls the board inlay card of making an uproar with it and connects on gear box body lateral wall.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a gear box of making an uproar falls in convenient installation type, includes the gear box body, gear box body lateral wall is equipped with and falls the board of making an uproar, it includes the casing to fall the board of making an uproar, seted up the amortization groove in the casing, and amortization groove one side is located the casing and is equipped with the amortization cotton.

Furthermore, a clamping groove is formed in the outer side wall of the gear box body, and a clamping block which is correspondingly matched and connected with the clamping groove is arranged on the side wall of the noise reduction plate.

Furthermore, the silencing grooves are rectangular and are arranged in the noise reduction plate one by one in parallel.

Furthermore, four noise reduction plates are included to cover four side faces of the gear box body, and two ends of the gear box body are connected with the ends of the rotating shafts and are not connected with the noise reduction plates.

The beneficial effects of the utility model are that, the utility model discloses a just, gear box of making an uproar falls in installation type sets gradually the amortization groove and packs the amortization cotton in falling the inboard of making an uproar, then accomplishes the back at the inside equipment of gear box body, falls the board inlay card with it and connects on gear box body lateral wall, and then has realized the absorption and the weakening to this internal noise of gear box, the effectual produced noise of gear box that has reduced.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a cross-sectional view taken at FIG. 1B-B;

fig. 3 is a partially enlarged view of fig. 2A.

In the figure, 1, a gear box body, 2, a noise reduction plate, 3, a shell, 4, a silencing groove, 5, silencing cotton, 6, a clamping groove and 7, a clamping block are arranged.

Detailed Description

Fig. 1 is the utility model discloses a structural schematic diagram, a just, gearbox of making an uproar falls in installation type, including gear box body 1, gear box body 1 lateral wall is equipped with and falls the board 2 of making an uproar, it includes casing 3 to fall the board 2 of making an uproar, the amortization groove 4 has been seted up in casing 3, and amortization groove 4 one side is located casing 3 and is equipped with amortization cotton 5.

As shown in the combined

drawings

1 and 2, a clamping groove 6 is formed in the outer side wall of the gear box body 1, and a clamping block 7 correspondingly connected with the clamping groove 6 in a matched mode is arranged on the side wall of the noise reduction plate 2.

Referring to fig. 2 and 3, the silencing slots 4 are rectangular and are arranged in parallel one by one in the noise reduction plate 2.

Referring to fig. 1 and 2, the noise reduction plates 2 cover four sides of the gear box body 1, and two ends of the gear box body 1 are connected to the rotating shaft and are not connected to the noise reduction plates 2.

During the use, set up amortization groove 4 in proper order and fill amortization cotton 5 in falling board 2 of making an uproar, then all assemble the completion back at 1 inside gears of gear box body, before 1 start-up work of gear box body, fall board 2 inlay card with it and connect on 1 lateral wall of gear box body, and then realized falling the absorption and the weakening of board 2 of making an uproar to 1 internal noise of gear box, the effectual produced noise of gear box that has reduced.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
