How It Works<\/h2>\n

At 1:1 ratio, the output shaft rotates at exactly the same speed as the input. The precision of this speed correspondence depends on gear manufacturing accuracy – Grade 5-6 ensures pitch error below 6 microns, translating to angular transmission error well within the 20 Arcmin backlash specification. For tighter applications, the factory low-backlash option achieves <=10 Arcmin through selective gear pair assembly.<\/p>\n

Structure and Material Details<\/h2>\n

The commutator housing is precision-bored on a horizontal machining center in one setup to ensure strict perpendicularity between input and output shaft bores – critical for minimal transmission error. Gear sets use selective fit: pairs are measured and matched to achieve closest possible contact pattern. Bearings are precision class P5 (ABEC5 equivalent). Shaft runout controlled to <0.01 mm TIR after assembly.<\/p>\n
