Abstract: The invention relates to a split-type nut assembly. The split-type nut assembly comprises a first nut and a second nut which are completely separated from each other. The first nut and the second nut have identical pitches and leads and are matched with each other or move relative to each other on a threaded shaft. Compared with the prior art, the split-type nut assembly has the advantages of being good in clearance elimination effect, long in service life, convenient to disassemble and the like.

Abstract: A linear stepping motor having anti-rotating screw is disclosed, comprising a stator, a rotor, a front-end cover, a rear-end cover and a screw, wherein the screw is an anti-rotating screw. The anti-rotating screw comprises a screw main body, one end of the screw main body is covered with a layer of plastic anti-rotating structure of injection molding. The front-end cover is provided with a segment of inner cavity, which is of shape matched with the anti-rotating structure, and the anti-rotating structure of the screw is in sleeved connection with the inner cavity of the front-end cover. The linear stepping motor in the present invention has the advantages in that the screw is free from limits in the processing length, has high strength, keeps high concentricity and other accuracy, and is of small error in use and less processing procedures, and saves working time. Less metallic profiles are consumed, energy is saved and the injection molding structure has a self-lubricating function, and when cooperating with the motor to perform linear motion, has a high efficiency and a long service life.

Abstract: A nonreversible anti-backlash nut comprises a first nut body and a second nut which are provided with internal threads, and a shrinkage ring which is capable of shrinking inwards in a radial direction and is disposed between the first nut body and the second nut body. Nut body chamfers are separately arranged on sides, connected with the shrinkage ring, of the first nut body and the second nut body. A shrinkage ring chamfer is arranged at a position, corresponding to the nut body chamfers, of the shrinkage ring. After the nut is assembled, the shrinkage ring provides a shrinkage force to push, via the chamfers, the first nut body and the second nut body away from each other, so that an axial clearance of the nut is eliminated. Compared with the prior art, the nut has a better and more uniform clearance elimination effect.
