Gear transmission noise has more than 30% of the causes from the burr, knock against injury. Some factories in front of the gear box assembly, remove burrs and knocked wounded, is a passive way. Comparative claims the following approach:

(1) gear shaft parts, gear hobbing gear department immediately after put on special plastic cases transferred after the procedure, and with a special plastic storage and shipment.

(2) the gear honing process, reduce the tooth surface roughness, deburring, and prevent the knock against, can effectively reduce gear noise

Appropriate to 1, the Sprocket wheel of firmness, too tight will increase power consumption, bearing wear and tear; Too loose Sprocket wheel easy to beat and take off the chain. Tightness of Sprocket wheel is: from the Sprocket wheel in the middle of the filed or under pressure, is about two Sprocket wheel center distance between 2% and 3%.

2, Sprocket wheel is installed on the shaft should not swing and skew. Two in the same transmission components Sprocket wheel face should be located on the same plane, Sprocket wheel center distance in 0.5 meters the following, to 1 mm deviation; Sprocket wheel center distance over 0.5 meters, can be deviation of 2 mm. But you can't have friction Sprocket wheel tooth flank phenomenon, if the two rounds of offset too prone to take off the chain and accelerated wear and tear. When changing the Sprocket wheel must pay attention to check and adjust the offset.

After 3, Sprocket wheel wear serious, should be replaced at the same time the new Sprocket wheel and the new Sprocket wheel, to ensure good contact. Can not only separate new Sprocket wheel or new Sprocket wheel. Otherwise it will cause bad meshing speed new Sprocket wheel or new Sprocket wheel wear. Sprocket wheel tooth surface wear to a certain degree to flip timely after using (Sprocket used adjustable surface), to extend the using time.
