The main transmission structure of the servo planetary reducer is: planetary gear, sun gear, and outer ring gear.
行星减速器因为结构原因,单级减速最小为3,最大一般不超过10,常见减速比为:3.4.5.6.8.10,减速机级数一般不超过3,但有部分大减速比定制减速机有4级减速。
Compared with other reducers, the servo planetary reducer has high rigidity, high precision (single-stage can be within 1 minute), high transmission efficiency (single-stage 97%-98%), high torque/volume ratio, and lifetime maintenance-free Features.
Because of these characteristics, most of the servo planetary reducers are installed on stepper motors and servo motors to reduce the speed, increase the torque, and match the inertia.
减速机额定输入转速最高可达到18000rpm(与减速机本身大小有关,减速机越大,额定输入转速越小)以上,工业级伺服行星减速器输出扭矩一般不超过2000Nm,特制超大扭矩伺服行星减速器可做到10000Nm以上.工作温度一般在-25℃到100℃左右,通过改变润滑脂可改变其工作温度。
