The principle of plan鐵懂etary reducer is a power transmissio學歌n mechanism, which uses the sp嗎長eed converter of gears to南要 reduce the rotation number of th妹鄉e motor to the desired rotation nu鐘資mber and obtain a me業月chanism with large torque.務資 The gears with fewer動哥 teeth on the transmi他子ssion shaft of the planetary reducer me視靜sh with the big gears on the outp城著ut shaft to reduce speed. Ordin得我ary reducers also have sever書暗al pairs of gears with the same p光學rinciple engaged to achieve the 術能ideal reduction effect. The r科藍atio of the number of teeth of big an媽道d small gears is the transmission 國著ratio.
Series: number of sets of planetar說暗y gears. As one set of plane西紙tary gears cannot meet the醫民 requirements of large transmission rat了厭io, sometimes two or th業工ree sets are required to meet th服員e user's requirements of lar能懂ge transmission ratio As the 民說number of planetary gears is in火去creased, the length o分海f the two-stage or three-stage reducer 新做will increase and the efficiency w厭窗ill decrease. Return clearan刀光ce: when the output end is fixed器制 and the input end rot生得ates clockwise and counter票女clockwise to make the吃遠 input end produce - 2% of the r醫冷ated torque, there is a small angular d通分isplacement at the input end of t讀嗎he reducer. This angular displac我睡ement is the return clearance. The 爸日unit is "minute&qu頻爸ot;, which is one sixtieth of one deg笑刀ree Some people call it ba爸制ck space. With the continuous develo睡業pment of the gear reducer in鐵我dustry, more and more enterprises have 吧低applied the gear reducer. The pla市紙netary gear reducer is an in光低dustrial product, and 喝著the planetary gear reduc作些er is a transmission mechanism. It生身s structure is closely connec雪坐ted to the gearbox housing by我和 an internal gear ring.體也 There is a sun gear driven by厭廠 external dynamic force in the ce舞輛nter of the gear ring. Be匠微tween the two, there is a gr雨劇oup of planetary gear sets 黑間which are composed of 河拍three gears equally on the tray, Thi雨白s group of planetary gears is support有廠ed by the output shaft, internal ge廠音ar ring and sun gear dur拿和ing the floating perio能照d; When the power at the input side dr弟可ives the sun gear, it can drive the pl女木anetary gear to rotate, and f城是ollow the path of the inner gear ring 微土to revolve along the center. The ro銀錢tation of the planet drive視民s the output shaft connec是小ted to the tray to outp會紙ut power. The speed 大鐵converter of the gear is use紙雪d to reduce the rotation numbe算劇r of the motor (motor) to the d農東esired rotation numbe笑通r, and a mechanism with large torque i是煙s obtained. Among the gear reduc窗讀er mechanisms used to transmit po作多wer and motion, the planetary gea答也r reducer is a precision讀銀 type gear reducer, and the reduction和信 ratio can be accurate to 0.1 r村路pm - 0.5 rpm.
