Abstract
The utility model relates to a novel precise chain transmitting in a gapless mode. The novel precise chain transmitting in the gapless mode comprises a plurality of connecting pieces, wherein the connecting pieces are mutually connected to form the chain, and are installed on a transmission shaft of the chain. The structures of the connecting pieces are symmetrical about the center; the connecting pieces comprise connecting shafts; the center of each connecting shaft is provided with three bearings; a nut, a first shaft sleeve, a transverse positioning bearing, a second shaft sleeve, a first plane thrust bearing, a big connecting sheet, a second plane thrust bearing, a small connecting sheet and a third plane thrust bearing are sequentially arranged from the end position of one end of each connecting shaft to the three bearings in the center, and are sequentially attached to each other, and the third plane thrust bearing is attached to the bearings. The novel precise chain transmitting in the gapless mode is reasonable in structure, and can bear large loads and accurately carry out positioning.
