Title:
TRANSLATIONAL TRANSMISSION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/219593
Kind Code:
A1
Abstract:
Disclosed is a translational transmission structure. The main components comprise a direct current electric motor (3), a synchronizing wheel (8), a synchronizing belt (9), a screw rod (4), a nut (5), a translational rail assembly (6), etc. The operation of the direct current electric motor (3) drives the synchronizing wheel (8) and the synchronizing belt (9) to rotate, wherein at the same time, the synchronizing wheel and the synchronizing belt are connected with the translational screw rod (4) to realize a rotation action, and a translational action of a base frame (1) with respect to a square frame (2) is realized by means of the translational screw rod (4) rotating in the relatively fixed nut (5). The structure of the screw rod and the nut (5) can prevent self-disengaging, the space occupied by assembling is smaller, and the requirement of various translational strokes can be easily satisfied by an adjustment in circuit control. The translational transmission structure is suitable for use with most operating beds with a requirement for a translational function.
