Abstract
The invention provides a noise reduction outer shell box used for an engine and belongs to the field of noise reduction environmental protection materials. The outmost side of the outer shell box is an outer guard plate, the outer shell box is arranged outside the engine, a noise reduction fiber layer and a noise absorbing cotton layer are arranged in the outer guard plate and bound by binding agent, and a noise reduction hole is formed in the outer guard plate. The noise reduction outer shell box used for the engine has the advantages that the noise reduction outer shell is arranged outside the engine so as to absorb and reduce noise which is produced in process of working of a brake device, reduce environmental noise, and prevent auditory health of an operator from not being affected in process of working of the engine.
Description
Technical fieldThe present invention relates to a kind of noise reduction casing box for motor, belong to noise reduction environment-friendly materials fields.
Background techniqueMotor (Engine) is called again engine, be a kind of can being converted into of other form another kind of can machine, normally be converted into mechanical energy to chemical energy.Sometimes it both had been applicable to power generating apparatus, also can refer to comprise the whole machine of power plant, such as petrol engine, and aeroengine.Motor is born the earliest in Britain, so the concept of motor also comes from English, its literal sense refers to the sort of " producing the mechanical device of power ".Motor is divided into piston engine, pressed engine, rocket motor, turbogenerator.Its working procedure is: air inlet-compression-oil spout-burning-expansion acting-exhaust, and due to these a series of processes, cause motor noise when work huge, produce noise pollution, unfavorable to people's sense of hearing health.
Summary of the invention
Defective in view of prior art exists the purpose of this invention is to provide a kind of noise reduction casing box for motor.
For achieving the above object; the technology used in the present invention solution is: a kind of noise reduction casing box for motor; the outermost of casing box is outer protecting sheet; casing box is arranged on outside motor; it is characterized in that: be provided with noise elimination layer of fibers and acoustical cotton layer in described outer protecting sheet; and bonding by tackiness agent, protecting sheet is provided with bloop outside.
Described noise elimination fiber layer thickness is 2-15mm.
Described acoustical cotton layer thickness is 2-15mm.
A kind of noise reduction casing box for motor, its beneficial effect is: the noise reduction shell is installed outside motor, is absorbed and reduce the noise that sends when braking device is worked, reduce ambient noise, Protection personnel sense of hearing health when engine operation is unaffected.
Description of drawings
Fig. 1 is a kind of structure diagram of the noise reduction casing box for motor.
Fig. 1 reference character is as follows: 1, outer protecting sheet, 2, the noise elimination layer of fibers, 3, the acoustical cotton layer, 4, tackiness agent, 5, bloop.
Embodiment
The below is described as follows a kind of noise reduction casing box for motor: a kind of noise reduction casing box for motor; the outermost of casing box is outer protecting sheet 1; casing box is arranged on outside motor; in described outer protecting sheet, 1 is provided with noise elimination layer of fibers 2 and acoustical cotton layer 3; and bonding by tackiness agent 4, protecting sheet 1 is provided with bloop 5 outside.
Claims (3)
1. noise reduction casing box that is used for motor; the outermost of casing box is outer protecting sheet (1); casing box is arranged on outside motor; in described outer protecting sheet, (1) is provided with noise elimination layer of fibers (2) and acoustical cotton layer (3); and bonding by tackiness agent (4), protecting sheet (1) is provided with bloop (5) outside.
