Title:
REDUCTION DRIVE MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/117692
Kind Code:
A1
Abstract:
A reduction drive mechanism comprises a base set (1), a drive rod (2), a displacement base (3, 5), and a drive gear (4, 6). The base set (1) comprises a base (11). The drive rod (2) is connected to the base (11). A first external thread (21) is disposed at a surface of the drive rod (2). A first internal thread (31, 51) is disposed internally in the displacement base (3, 5), and a second external thread (33, 53) is disposed on a surface of the displacement base (3, 5). The pitch of the second external thread (33, 53) exceeds that of the first internal thread (31, 51). The first external thread (21) of the drive rod (2) is screwed into the first internal thread (31, 51). The drive gear (4, 6) comprises a second internal thread (41, 61). The second external thread (33, 53) of the displacement base (3, 5) is screwed into the second internal thread (41, 61). When the drive rod (2) rotates, since the pitch of the second external thread (33, 53) exceeds that of the first internal thread (31, 51), a rotation speed of the drive gear (4, 6) is less than that of the drive rod (2).
