DEVICE FOR CONVERTING RECIPROCATING RECTILINEAR MOTION INTO UNIDIRECTIONAL CIRCULAR MOTION AND TRANSPORTATION VEHICLE USING DEVICE

摘要

A device for converting a reciprocating rectilinear motion into a one-way circular motion. A hand-driven rectilinear motion mode can be converted into a one-way circular motion mode by a combination of a rack and a gear or a combination of a chain and a chain wheel or a combination of a belt and a belt wheel, and conversion between multiple gear sets and one-way bearings. The device is simple and compact in structure. Each gear set comprises a large gear, an intermediate gear and a small gear, so a mode of transforming an output torque and rotating speed can be achieved by transverse sliding engagement of the gear sets, and the speed is conveniently adjusted. Besides, the gear sets in a device main body are randomly arrayed according to actual requirements, such as linear arrangement and triangular arrangement, or the combination quantity of the gear sets and the number of gears in the gear sets can be increased or decreased according to actual requirements. In addition, the gears in the gear sets can be arrayed according to the size sequence of large, medium and small, can realize step-by-step variable-speed transmission, or can be arrayed according to the mode of small, medium and large and realizes jump variable-speed transmission. Moreover, also provided is a transportation vehicle using a device.
