Abstract
The invention discloses a transmission mechanism driven by a unidirectional rotating lead screw to move back and forth, and belongs to the field of mechanical transmission. The back and forth linear movement is an important movement mode of many machines, and the back and forth linear movements achieved through existing methods such as crank-connecting rod mechanisms have advantages and disadvantages respectively. According to the transmission mechanism driven by the unidirectional rotating lead screw to move back and forth, staggered forward and reverse lead screw sliding grooves are formed in the lead screw, return grooves are formed in the fixed back-and-forth positions, and a special transmission assembly is mounted on a back-and-forth sliding block, are inserted into the sliding grooves to drive the sliding block to do constant-speed unidirectional movement along with rotation of the lead screw, returns at the return groove to do reverse constant-speed movement along the reverse sliding groove, and repeats the back-and-forth actions through the return in the other end. In this way, the transmission mechanism of which the lead screw unidirectionally rotates to drive an object to do constant-speed back-and-forth movement in a long distance can be realized.

Specific embodiment
It is described in detail below in conjunction with the accompanying drawings and to embodiments of the invention, a kind of single direction rotation leading screw can promote round
The transmission mechanism of motion, by leading screw（2）On process with positive and negative two kinds leading screw sliding grooves staggeredly（6）（7）, fixed past
Return position and open left and right return slot（1）（5）, in round slide block（3）It is upper that special transmission component is installed（4）, transmission component（4）Insert
Enter in chute, with the slide block that rotarily drives of leading screw at the uniform velocity one-way movement is done, and in left return slot（1）Place returns, with reverse slide
The reverse uniform motion of groove, and by right return slot（5）Reciprocating action.
A kind of described single direction rotation leading screw can promote the transmission mechanism of back and forth movement, according to fixed round distance, plus
