Planetary Gearheads

World Association of planetary gear reducer main structure: planetary gear, sun gear, a planetary ring gear reducer World Association because structural reasons, a minimum of three single-stage reduction, the maximum is generally not more than 10, a common reduction ratio is: 3.4.5.6 .8.10, gear progression is generally not more than three. Compared to other gear, World Association planetary gear with high rigidity, high precision (single stage can be done within three points), high transmission efficiency (single stage in 97% -98%), high torque / volume ratio, lifetime free maintenance and so on. Because of these characteristics, the World Association of planetary gear is installed on the majority of stepper motors and servo motors, used to reduce the speed, improve torque, matched inertia. reducer rated input speed can reach 18000rpm (with reducer itself the size, the greater the reduction gear, rated input speed is smaller) than the industrial stage planetary gearbox output torque is generally not more than 2000Nm, special large planetary gear torque can be achieved over 10000Nm working temperature is generally -25 ℃ to 100 ℃ so, by changing its operating temperature grease can change several concepts about planetary gearhead: series: the number of sets of planetary gears can not be met due to a larger star gear ratios, sometimes two or three sets to sets. support to meet the requirements of the larger gear ratio gear due to the increased number of stars, so the length of two or three gear will increase the efficiency will decline backlash: the output of fixed inputs along clockwise and counterclockwise rotation, so that the input terminal to produce rated torque + -2% when the torque, speed reducer input terminal there is a slight angular displacement, the angular displacement is the backlash. The unit is divided ¨ ¨, that is, once very six one. It was also known as backlash. World Association of planetary reducer is a widely used industrial product, its performance with other military-grade gear comparable products, but has a price of industrial products, is applied to a wide range of industrial applications.
