Planetary reducers have very high precision, with accuracy within 3 arc minutes, and there is room for further improvement.
Planetary reducers are classified into three grades. The precision of planetary reducers from Grade 1 to Grade 3 ranges from 3 arc minutes to 8 arc minutes. The lower the grade, the higher the precision. With the continuous advancement of research and development technology, planetary reducers can achieve even higher precision, with the potential to reach 1 arc minute or even higher.
Many factors can affect the precision of a planetary reducers. These include the dimensional accuracy of machine parts, the compliance of operators during installation, the spacing and geometric precision between guide rails, and the dimensional accuracy of parts used for transmission. If the parts of a planetary reducers are not standardized, they can hinder bearing rotation, increase resistance, and affect the machine's precision. The precision of the guidance system is affected by the gaps and geometric precision between the guide rails, so it is important to calibrate the gaps between the guide rails. The parts used for transmission must also meet high-quality standards; otherwise, they will affect the precision of the transmission system.
