Analysis and treatment method of planetary gear box noise

     Planetary gear box is the important components widely used in mechanical transmission, a pair of gear meshing, becauseinevitably pitch, tooth shape error, in the operation can be generated in the process of meshing impact and noisecorresponding to the gear mesh frequency, between the tooth surface due to phase noise on the sliding friction. The gear is basic part of gear box drive, reduce gear noise control ofgearbox noise is very necessary. Generally speaking, the causes of gear noise occurred mainly in the following aspects:

     1.Gear design. Improper choice of parameter, coincidence is too small, the tooth profile modification of inappropriate or nomodification, the gear box structure is not reasonable. Gear processing base pitch error and tooth profile error is too large,the tooth side clearance is too large, the surface rough.

     2.Gears and gear box. The contact assembly eccentricity, low precision, parallel shaft, shaft, bearing, bearing stiffness, rotaryaccuracy of the bearing is not high and the gap of inappropriate.

    3.Other aspects of input torque. The load torque fluctuation,torsional vibration, electric motors and other gearing balanceetc.

Planetary Gearbox

     After many years of efforts and continuous exploration, the United States successfully introduced the world's advanced Blu-Goosuper lubricant, a lubricant is a special kind of inert materialshave a variety of applications, mainly used to reduce the metal to metal contact. As a kind of thread sealing compound, the productform a contact surface between the external and internal threads,can protect the joints from friction and wear, and can withstand 1407 kg / cm2 pressure, and even wear, corrosion or the wrongthread surface machining. 

     Gear box additive this product is alsoan excellent, can form a layer of film in the interior to pieces. To reduce friction, gear noise and leakage. It also significantly reduce the torque stress to meet the power demand,decompression. It can be used for gasket faces or as a filler added, the seal to prevent leakage of fluid, can be applied at the temperature of 316 DEG C success, to reduce the noise of thegear box.
