Causes for the shaping of the gear noise

There are numerous causes for the shaping of the gear noise, especially high burden and high speed of process, noise and shaking is ever pressing trouble to be overtake. The aims and countermeasures to bring down the noise of finish in accord with this description Cheung added attending to the noise trouble could be greatly bettered.

(1) choice of the fine accuracy of the gear pitch error, profile error and divergences of tooth, tooth error piecemeal, noise by nature get littler. Grinding tooth surface, as well the gear and the varied precision can[2] be improved, just as well changed tooth surface roughness. Therefore, to bring down noise of.

(2) enquiry Morocco smooth the tooth surface, rub (lapping up), Tobe mill (Honing) can[2] accomplish a actually satisfactory tooth surface roughness warm operation for some time, and the other in the oil may also improve the tooth surface rowdiness, noise were brought down part.

(3) adjust tooth contact drum treating execution of the tooth surface (Crowning) or cut-end treating (Relieving) to keep monumental adjoin, will by nature bring down the noise. Suitable toothed dressing out is likewise efficient in bringing down noise. Evacuation of the tooth surface bumps or arrive at the mark.

(4) The suitable backlash pulsing nature of the revolution, the littler the backlash of noise reducing assist. Commonly greater than the balance of load, backlash is slimly bigger than the reducing in noise. Favourable.

(5) the littler the greater occlusal range occlusion range the bigger the noise, thus bringing down the pressing angle, or enhancing teeth deep bite rate could gain. The overlap rate increase could likewise bring down the noise, and so the helical gear is littler than the spur gear noise.

(6) a less gear lower modulus and littler external diameter.

(7) a greater rigidness broadened teeth parcels, the high up rigidness of the shape of the advantage of decreased noise. Fortify the gear box and axle rigid

(8) with quivering little decay rate of the material for easy burden low revolution of gear, plastic gear is a fine selection, but pay attending to the temperature arise. Cast iron gear than steel gears bring down noise.

(9) the suitable lubrication execution sufficient lubrication of high viscousness oil quieter.cycloid gearbox

(10) rotations of the low-speed procedure and low load gear downward as far as possible, to minimise the load could bring down the noise
