The gears of the servo planetary reducer are divided into straight teeth and helical teeth. The main differences are: the high precision of straight teeth and the helical noise of helical teeth.
As far as the structure of the planetary reducer is concerned, the planet carrier of the helical gear planetary reducer must be supported by a double support structure.
The planet carrier of the servo planetary reducer can be used for single support or double support.
However, the accuracy, noise and efficiency of the spur gear on a single support are much lower than that of the spur gear on a double support.
The double-support spur gear planetary reducer is compared with the helical gear planetary reducer.
Since the precision of the helical gear of the servo planetary reducer is higher than that of the spur gear, the precision of the helical planetary reducer will be higher.
