What is the reduction ratio of a planetary gearbox?
The number of stages, also called segments, of an ordinary planetary gearbox is indicated by L1 and L2.
Some of the reduction ratios represented by L1 are as follows:
2 ratio, 3 ratio, 4 ratio, 5 ratio, 7 ratio, 10 ratio
L2 represents some of the following reduction ratios:
12 ratios, 15 ratios, 20 ratios, 25 ratios, 30 ratios, 35 ratios, 40 ratios, 50 ratios 70 ratios, and 100 ratios.
Example: Model PLF060-10-S2-P2
PLF: Standard series model designation
060: Box number designation
10: reduction ratio
S2: Standard output shaft.
P2: Standard factory accuracy.
