The utility model discloses have can auscultation mechanical transmission the abnormal sound, accurately judge the mechanical transmission trouble, simple structure, convenient to use's positive effect.
Description
Technical field
This utility model relates to mechanically operated maintenance tool technical field, particularly relates to a kind of machine driving abnormal sound detection assistor.
Background technology
When at present break down in machine driving position, it is necessary first to judge whether drive disk assembly has abnormal sound according to sound, as being against on certain machine driving position of automobile, careful auscultated sound has no abnormal sound significant change.Traditional way is directly ear to be leaned against the machine driving position auscultated sound broken down to have no abnormal sound.Owing to, in mechanical transmission course, a lot of noise signal frequency can be produced, disturb people's auscultation to abnormal sound sound, thus affect the judgement to machine driving fault.
Summary of the invention
The purpose of this utility model is to provide a kind of machine driving abnormal sound detection assistor, with reach can the mechanically operated abnormal sound of auscultation, accurately judge machine driving fault, simple in construction, purpose easy to use.
Machine driving abnormal sound provided by the utility model detection assistor, the sound conductive bar surveyed end and connect therewith is touched including sound source, it is characterized in that: described sound source is touched the front end of survey end and is provided with circular arc tip, the other end of described sound conductive bar is provided with groove, and the cross-sectional area of described groove is less than the cross-sectional area of sound conductive bar.
Machine driving abnormal sound provided by the utility model detection assistor, the other end of sound conductive bar is provided with groove, when whether needs auscultation mechanical transmission component has abnormal sound, sound source is touched and is surveyed end in contact at mechanical transmission component, human ear leans against in the groove of sound conductive bar, and groove is fastened in human ear, is possible to prevent the interference of other noise signal frequencies, enable people to accurate auscultation abnormal sound sound, accurately judge machine driving fault.Therefore, this utility model have can the mechanically operated abnormal sound of auscultation, accurately judge machine driving fault, simple in construction, good effect easy to use.
Accompanying drawing explanation
Accompanying drawing part discloses this utility model specific embodiment, wherein,
Fig. 1, structural representation of the present utility model；
Fig. 2, structure top view of the present utility model；
Fig. 3, the structural representation of groove of the present utility model.
Detailed description of the invention
As it is shown in figure 1, machine driving abnormal sound provided by the utility model detection assistor, touching the sound conductive bar 2 surveyed end 1 and connect therewith including sound source, the other end of sound conductive bar 2 is provided with groove 3.
This utility model is in use, when whether needs auscultation mechanical transmission component has abnormal sound, sound source is touched survey end 1 and is contacted at mechanical transmission component, human ear leans against in the groove 3 of sound conductive bar 2, groove 3 is fastened in human ear, it is possible to prevent the interference of other noise signal frequencies, enables people to accurate auscultation abnormal sound sound, accurately judge machine driving fault.Under mechanical transmission component normal operation, sound is the most soft, not vibration；When mechanical transmission component breaks down, there is oscillation phenomenon, sound is ear-piercing, irregular, with the abnormal sound of " click " etc.Therefore, it can according to whether mechanical transmission component has abnormal sound, accurately judge whether machine driving breaks down.
Above-mentioned sound source is touched the tip of survey end 1 and is provided with circular arc tip 4.Circular arc tip 4 can soft with mechanical transmission component contact, with anti-scratch or damage mechanical transmission component.
As in figure 2 it is shown, the cross-sectional area of above-mentioned groove 3 is less than the cross-sectional area of sound conductive bar 2.The horizontal contact face 203 of one week is had between cross section and the cross section of sound conductive bar 2 of groove 3, when groove 3 is fastened on human ear, horizontal contact face 203 is enclosed in around human ear, prevents the auscultation of other noise effect abnormal sound sound, can accurately judge machine driving fault.If not having horizontal contact face 203 or horizontal contact face 203 too small, then groove 3 and sound conductive bar 2 are point cantact, form a contact tip, and when human ear auscultation abnormal sound sound, contact tip easily hurts human body.
As it is shown on figure 3, groove 3 can be the hemispherical caved inward, it is also possible to for the trapezoidal column caved inward, the size of groove 3 is preferred with bigger about human ear.
Above-mentioned sound source is touched survey end 1 and sound conductive bar 2 and is made up of alloy one cast.Sound is in different media, and spread speed is different, the most especially the fastest to propagate in solids, and the most especially propagates the fastest with metal.In nature, simple metal quantity is little, and great majority are alloy.Therefore, sound source is touched and is surveyed end 1 and sound conductive bar 2 and be made up of alloy one cast, and not only sound propagation velocity is fast, and one cast, not welding or assemble, and propagation medium is uniform, be convenient for people to can accurate auscultation abnormal sound sound, accurately judge machine driving fault.
Above-mentioned sound source is touched survey end 1 and sound conductive bar 2 and is made up of the one cast of solid rustless steel.Stainless steel, quality is hard, is unlikely to deform, acoustic excellent effect, it is possible to accurately judge machine driving fault.
It is provided with anti-slip veins 5 in above-mentioned sound conductive bar 2.When people's auscultation abnormal sound sound, need to hold with a hand or help sound conductive bar 2, anti-slip veins 5 to be possible to prevent hands to skid, reduce the external interference judging machine driving fault.
Claims (4)
