Also called the gear box, planetary gear box planetary gearbox gear box (Planetary Gearbox), the structure that a plurality of planetary gear around a sun wheel rotation mechanism, the transmission ratio is reduced, and themotor torque is proportional to increasing mechanism.

Features: compared with other ordinary gear box with physics, transfer smoothly, large bearing capacity, small space with large transmission ratio, especially in life. If the gear is steel, life of up to 1000H, small volume,beautiful appearance

Application: planetary gear box, application is very extensive, initially with a motor, in addition to the micro motorused for sunshade industry, office automation, intelligent Home Furnishing, production automation, medical,financial machinery, computer games and other fields. Such as automatic curtain, counting intelligent closestool,lifting system, machine, advertising light boxes and so on

Currently on the market the planetary gear box are 16MM in diameter, 22MM, 28MM.32MM, 36MM, 42MM, andmotor coordination, its function can achieve load torque load speed: 3-2000RPM: 50KG 1-30W

Planetary gear box: level: i= (internal gear tooth number / sun gear tooth number) +1

Multi level: i=i1Xi2Xi3...

Edit this paragraph noise analysis and processing method

Planetary gear box is the important components widely used in mechanical transmission, a pair of gear meshing,because inevitably pitch, tooth shape error, in the operation can be generated in the process of meshing impactand noise corresponding to the gear mesh frequency, between the tooth surface due to phase noise on thesliding friction. The gear is basic part of gear box drive, reduce gear noise control of gearbox noise is verynecessary. 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 ofinappropriate or no modification, 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, bearingstiffness, rotary accuracy 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 gearingbalance etc..

After many years of efforts and continuous exploration, the United States successfully introduced the world's advanced Blu-Goo super lubricant, a lubricant is a special kind of inert materials have a variety of applications,mainly used to reduce the metal to metal contact. As a kind of thread sealing compound, the product form acontact surface between the external and internal threads, can protect the joints from friction and wear, and canwithstand 1407 kg / cm2 pressure, and even wear, corrosion or the wrong thread surface machining. Gear boxadditive this product is also an 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 the gear box.
