As preferably, spacer sleeve (8) design has the 5-8 bar to be used for installing the axial roller groove (12) of steel ball roller (2a).
As preferably, every group of steel ball roller (2a) number is at least 3 in the axial roller groove (12) of spacer sleeve (8).
As preferably, be provided with lining (9) between spacer sleeve (8) and the mobile shell (1).
As preferably, mobile shell (1) is provided with concave arc groove (10), outward together with the step belt.
As preferably, lining (9) two ends are respectively equipped with the inner ring (9a) that is used for locating spacer sleeve (8); Lining (9) shaft end also is provided with back-up ring (3a), forms shoe cream room (9c) between inner ring (9a) and the back-up ring (3a).
As preferably, connect by clamping screw (7a) between back-up ring (3a) and the mobile shell (1).
The utility model has designed a kind of circular shaft line slideway new construction, and compared with prior art, beneficial effect is as follows:
1, precision height in the straight line work, the gap is little between the steel ball roller that the circular shaft guide rail is mated, good response speed and sensitivity are arranged during the mobile shell moving linearly, reliable and stable, especially in the actual use of computerized emboridering machine, can well guarantee the quality of embroidery pattern.
2, be sleeved on steel ball roller on the circular shaft guide rail, load is evenly distributed, and lubricated advantages of simple is set, and it is little to wear and tear, the service life of having strengthened guide rail mechanism.
3, reasonable integral structure, easy accessibility, low cost of manufacture.
