Abstract
The utility model relates to the technical field of escalators, in particular to a noise-reducing device for an escalator drive chain wheel, which includes a drive chain wheel body, wherein polyurethane blocks are arranged in the tooth sockets of the drive chain wheel body. The noise-reducing device for the escalator drive chain wheel can effectively reduce the noise in the transmission process.
Description
Technical field:
The utility model relates to the staircase technical field, relates in particular to a kind of staircase driving sprocket wheel denoising device.
Background technique:
Staircase is a kind of circular flow step that has; The fixedly electric drive equipment of conveying people is used for tilting up or down; Its structure is mainly by step, step driving unit, driving host, transmission part, nervous device, balustrades, Structural Hardware, step roller track, cover plate, comb floor plate, safety installations and the electrical part parts that grade are formed up and down; Has continuous operation; The characteristics that transport volume is big are widely used in the vertical transportation of the public places such as subway, light rail, station, airport, harbour, shop and mansion that the stream of people concentrates.
Existing staircase, its driving sprocket wheel are when the chain drive-belt transmission, because the frictional impact between driving sprocket wheel and the chain drive-belt can produce bigger noise.
The model utility content:
The purpose of the utility model is to the deficiency of existing technology a kind of staircase driving sprocket wheel denoising device to be provided, and can effectively reduce the noise in the transmission process.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of staircase driving sprocket wheel denoising device, it comprises the driving sprocket wheel body, is provided with polyurethane block in the teeth groove of said driving sprocket wheel body.
Offer fixed groove in the teeth groove of said driving sprocket wheel body, said polyurethane block is flush-mounted in the fixed groove.
Said polyurethane block is positioned at the neutral position of teeth groove.
The utility model beneficial effect is:
The said a kind of staircase driving sprocket wheel denoising device of the utility model, it comprises the driving sprocket wheel body, is provided with polyurethane block in the teeth groove of said driving sprocket wheel body, the utility model can effectively reduce the noise in the transmission process.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the described a kind of staircase driving sprocket wheel denoising device of the utility model, its structure is that it comprises driving sprocket wheel body 1, is provided with polyurethane block 2 in the teeth groove 10 of said driving sprocket wheel body 1.
Further, offer fixed groove 3 in the teeth groove 10 of said driving sprocket wheel body 1, said polyurethane block 2 is flush-mounted in the fixed groove 3, installs and fixes simple.Preferably, said polyurethane block 2 is positioned at the neutral position of teeth groove 10, can play the effect of best noise reduction.
The described a kind of staircase driving sprocket wheel denoising device of the utility model; Owing in the teeth groove 10 of driving sprocket wheel body 1, polyurethane block 2 is set; When driving sprocket wheel during in the chain drive-belt transmission; Can reduce, reduce the frictional impact between driving sprocket wheel and the chain drive-belt, thus the noise that is produced when reducing transmission.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
