Abstract
The invention discloses a low-noise gear box. The low-noise gear box comprises a gear box body, a plurality of gear shafts arranged inside the gear box body and a plurality of gears penetrating through the gear shafts, and further comprises sound absorption cotton located on the periphery of the gear box body. The two end faces of each gear are provided with gear grooves, wherein the two gear grooves are not communicated with each other. The gear grooves are provided with the sound absorption cotton. The sound absorption cotton adheres to the gear grooves. Due to the fact that the periphery of the gear box body and the gear grooves are provided with the sound absorption cotton, the noise produced in the gear transmission process is effectively lowered; by means of a C-shaped check ring and a spring, no gap exists in the radial direction in the gear transmission process, and the noise produced through the gear transmission is effectively reduced.
Description
Technical field
The present invention relates to a kind of gear-box, relate in particular to a kind of gear-box of low noise.
Background technique
Gear uses extensively, multiple fields such as toy, elevator, lathe, subway, wind energy industry, wrist-watch are used, mainly bear transmission, change direction, deceleration or accelerating function, gear transmission is the mechanical transmission of utilizing the intermeshing transferring power of the gear teeth of two gears and motion, divide parallel axes column gear transmission, concurrent aces Bevel Gear Drive and alternating axis helical gear drive by the relative position of Gear axis, there is the features such as compact structure, efficiency is high, the life-span is long.Gear transmission refers to the device that directly transmits motion and power with the driven wheel gear teeth, in all mechanical transmission, gear transmission is most widely used, can be used to transmit motion and the power between the not far diaxon of relative position, gear-driven feature is: gear transmission is steady, and velocity ratio is accurate, and reliable operation, compact structure, efficiency is high, the life-span is long, the power, speed and the dimensional range that use are large, and for example transmitted power can be from very little to hundreds of thousands kilowatt; Speed reaches as high as 300m/s; Gear diameter can be from several millimeters to more than 20 meters, but can produce noise in gear transmission, and while running up, noise is larger, affects surrounding environment, and human body is damaged.
In view of above-mentioned defect, be necessary to design a kind of low noise in fact and improve.
Summary of the invention
Technical problem to be solved by this invention is: the problem that acoustical cotton is set in gear-box solves the generation noise of gear operation.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of gear-box of low noise, comprise gear case body, be arranged on several gear shafts in gear housing and several gears through gear shaft, also comprise acoustical cotton, acoustical cotton is positioned at gear case body surrounding.
Further, described gear both ends of the surface are provided with gear groove, between two gear grooves, do not communicate.
Further, described gear groove is provided with acoustical cotton, and acoustical cotton is by bonding in gear groove.
Further, described gear shaft is provided with ring toothing wheel shaft groove, and gear is positioned in the middle of two gear shaft grooves.
Further, described gear shaft groove is provided with C type back-up ring, C type back-up ring respectively with gear face mutually in succession.
Further, described gear shaft groove is provided with spring, and spring is positioned at C type ring washer another side.
Further, described C type ring washer and number of springs several.
By in gear housing surrounding and gear groove, acoustical cotton being set, effectively reduce the noise in gear transmission, ensure that by C type ring washer and spring gear is when the transmission, radial direction is very close to each other, effectively reduces gear-driven noise.

Embodiment
As depicted in figs. 1 and 2, comprise gear case body 1, be arranged on several gear shafts 2 in gear housing 1 and several gears 3 through gear shaft 2, also comprise acoustical cotton 4, acoustical cotton 4 is positioned at gear case body 1 surrounding, described gear 3 both ends of the surface are provided with gear groove 5, between two gear grooves 5, do not communicate, described gear groove 5 is provided with acoustical cotton 4, acoustical cotton 4 is by bonding in gear groove 5, be that described gear shaft 2 is provided with ring toothing wheel shaft groove 6, gear 3 is positioned in the middle of two gear shaft grooves 6, be that described gear shaft groove 6 is provided with C type back-up ring 7, C type back-up ring 7 respectively with gear 3 end faces mutually in succession, described gear shaft groove 6 is provided with spring 8, spring 8 is positioned at C type ring washer 7 another sides, be described C type ring washer 7 and spring 8 quantity several.
The noise producing in the time that gear 3 rotates absorbs by the acoustical cotton 4 of the acoustical cotton 4 above gear 3 and gear case body 1, in order to ensure axle vibration, adopts spring 8 and C type ring washer 7 fastening.
By acoustical cotton 4 being set in gear housing 1 surrounding and gear groove 5, effectively reduce the noise in gear 3 transmissions, ensure that by C type ring washer 7 and spring 8 gear 3 is when the transmission, radial direction is very close to each other, effectively reduces gear-driven noise.
The present invention is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection scope of the present invention.
