關(guān)于行星齒輪減速機(jī)的結(jié)構(gòu)及概念英文翻譯 |
The planetary gear reducer drive structure: the planetary gear, sun gear, internal gear.Planetary gear because of structural reasons, single-stage deceleration minimum 3, maximum is generally not more than 10 common reduction ratio: 3.4.5.6.8.10 reducer series is generally not more than three, but there are some large reduction ratio custom reducer 4 deceleration. Compared to other speed reducer, planetary reducer with high rigidity, high accuracy (single level can be achieved within 1 minute), high transmission efficiency (single stage in 97% -98%), high torque / volume ratio, life-long maintenance-free and so on. Because of these characteristics, the majority of the planetary gear is installed on the stepper motor and servo motor to reduce speed, increase torque, matching the inertia.Planetary gear rated input speed to a maximum reach 18000rpm (with reducer the size, the greater the speed reducer, the smaller the rated input speed) or more, industrial-grade planetary reducer machine output torque is generally no more than 2000Nm, the specially designed super-torque planetary reducer machine do 10000Nm. Working temperature -25 ℃ to 100 ℃, its operating temperature can be changed by changing the grease.Precision planetary gear backlash rating (arc minutes) is very important, backlash level price difference is quite large, planetary reducer can do multi-gear box links the maximum reduction ratio up to 100,000 with the servo motor so.Series: the number of sets of planetary gears. A star gear can not meet the large transmission ratio is sometimes necessary to support large transmission ratio requirements to meet two sets or three sets due to the increase of the number of stars in gear, so the two or 3 the length of the reducer will increase in efficiency will decline. backlash: will output the fixed input clockwise and counterclockwise rotation, the input to generate the rated torque of + -2% torque , a slight angular displacement of the input end of the reducer, this angular displacement is the backlash unit is the "points", that is, once the sixtieth was also known as backlash.
