Document Type and Number:
WIPO Patent Application WO/2017/045316
Kind Code:
A1
Abstract:
A reduction gear device, comprising a base (1) and transmission groups (2,3), the bases (1) being provided with a guide bar (12) connected to a baseplate (11), the transmission groups being provided with a first transmission shaft (21) and a second transmission shaft (22) that are pivotally connected to the baseplate, and a displacing plate (23) sleeved and connected to the circumference of the guide bar by means of a through hole such that the displacing plate (23) is moveable back and forth transversely on the guide bar (12), a first outer screw (211) and a second outer screw (221) being provided, in different pitches, on the surfaces of the first transmission shaft (21) and the second transmission shaft (22) respectively, the displacing plate (23) being provided inside with a first inner screw (231) and a second inner screw (231) screwed to the first outer screw (211) and the second outer screw (221), respectively, such that the first transmission shaft (21) is rotated and drives the displacing plate (23) to translate on the guide bar (12), enabling the displacing plate (23) to displace so as to drive the second transmission shaft (22) to rotate. The speed is switched by means of the screws, thereby simplifying the reduction gear device, facilitating maintenance, and reducing usage costs.
