Title:
ANGULAR DISPLACEMENT MICRO-DRIVING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/114869
Kind Code:
A1
Abstract:
An angular displacement micro-driving mechanism, comprising an input shaft (1), a hollow shaft (2), a gear I (3), an elastic retainer ring I (4), an elastic retainer ring II (5), a sleeve I (6), a gear IV (7), a power output shaft (8), a sleeve II (9), a bearing I (10), a bearing end cover I (11), a bolt I (12), a rotary workbench (13), a bearing II (14), a bearing end cover II (15), a bolt II (16), a gear III (17), a shaft sleeve (18), an intermediate shaft (19), a planetary carrier (20), a gear II (21), a sleeve III (22), a support (23), a bearing III (24), a bearing end cover III (25), a bolt III (26), a bearing IV (27), a bearing end cover IV (28), a worm gear (29), a worm (30), a sealing ring (31), a bolt IV (32), a retainer ring (33), an elastic washer (34), a nut (35), and a box (36). The hollow shaft (2) passes through a shaft hole of the box (36), and is fixed on the box (36) by the bolt IV (32) by means of a fixing shaft section (204) and a fixing protrusion (205) on the hollow shaft (2); the bolt IV (32) also fixes the bearing end cover IV (28); the gear I (3) is mounted on a spline II (202) on the hollow shaft (2) by means of a spline, and is pressed against a hollow shaft protrusion (203) on the hollow shaft (2) by means of the elastic retainer ring I (4). Precise angular displacement transmission can be achieved.
