Small deceleration motor slowdown motor structure and a fine accuracy requirement, about the gear motor skill manipulation has strict requirements: 1. Casting box after aging treatment is necessary. 2. Base and the lid closed box, not tighten bolts, with 0. 05 mm feeler to see subdivision surface touch and sex, feeler into depth shall not be greater than 1/3 of the width of the subdivision surface. 3. Base and the lid closed box, edge should be flush, chief & gt; 1200 mm, the dislocation is not more than 2 mm per side each other, and general & ge; 1200 mm, the dislocation is not more than 3 mm per side each other. 4. Bearing hole of the ellipse degree and straight degree according to the magnitude 7 GB1184 - precision1996. 5. Bearing hole end face with its axis is not straight degree according to the magnitude 7 GB1184 - precision1996. 6. The axis of the bearing hole and the subdivision surface contact ratio greater than zero. 2 to 0. 3mm. 7. Bearing hole centerline is not parallel, public service center line skew male servants, bearing hole center distance limit error (Cylindrical gear drive), bearing hole centerline disjoint public servants, the Angle of the center line of the limit of error (Cone gear drive), bearing hole centerline skew male servants, bearing hole center distance limit error (Worm drive)Should fit the design requirements.
