The technical solution adopted in the present invention is as follows:
A kind of rotor bearing mold insert, comprise integral formula structure mold insert, described mold insert structure in the arc-shaped, the outer surface of described mold insert is cylindrical, and its inner surface is endoporus; The two ends being positioned at mold insert are formed with the first inclined-plane and the second inclined-plane respectively, and described mold insert cylindrical has parallel notch, and the two ends of described notch are formed with inclined-plane respectively, coordinate and install magnetic part, the cylindrical of described mold insert also has tank filler sleeve in described notch.
Further improvement as technique scheme:
Also comprise the rotor bearing coordinating with mold insert and install, the outer ring of described rotor bearing is provided with inclined-plane, outer ring first and inclined-plane, outer ring second; Inclined-plane, described outer ring first coordinates with the second inclined-plane of mold insert and abuts, and inclined-plane, described outer ring second coordinates with the first inclined-plane of mold insert and abuts;
Described mold insert cylindrical has three parallel notches, be respectively the first notch, the second notch and the 3rd notch, the two ends of described first notch are formed with the 3rd inclined-plane respectively, the two ends of described second notch are formed with the 4th inclined-plane respectively, and the two ends of described 3rd notch are formed with the 5th inclined-plane respectively;
The length of described three parallel notches is equal, the inclined-plane that every bar notch two ends are formed is consistent, its angle of inclination is consistent with incline direction, and described first notch is consistent with the width of the 3rd notch, and the width of described second notch is greater than the width of the first notch and the 3rd notch.
Described mold insert adopts plastics.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, rationally; The material that mold insert adopts is plastics, adopt one-shaping technique, easy to make, the uniformity of three notches can be ensured simultaneously, magnetic part is fit in three notches, coordinate with the inclined-plane of three notches respectively and abut, its registration is high, thus three minim gaps between three bottom surfaces to flux sleeve that ensure that the magnetic part of insertion three notches are all equal; Owing to not allowing magnetic conduction between magnetic part and mold insert, this insert material adopts non-magnetic plastics to be also very reasonable; Rotor bearing outer ring of the present invention is designed with ramp structure, and the both ends of the surface of mold insert also adopt ramp structure, and that can coincide very much when assembling is combined together, and plays locking effect; In addition, the interchangeability of mold insert and outer ring is also very good, and mold insert and outer ring can dismounting and change at any time; Bearing, after a period of time that runs up, can be undertaken supplementing by tank filler sleeve and refuel.The present invention can improve open-end spinning rotor bearing rotary speed, extend the life-span of rotor bearing, improves the quality of spinning.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the rotor bearing mold insert of the present embodiment, comprises integral formula structure mold insert 15, mold insert 15 structure in the arc-shaped, and the outer surface of mold insert 15 is cylindrical 10, and its inner surface is endoporus 11; The two ends being positioned at mold insert 15 are formed with the first inclined-plane 1 and the second inclined-plane 9 respectively, and mold insert 15 cylindrical 10 has parallel notch, and the two ends of notch are formed with inclined-plane respectively, coordinate and install magnetic part, the cylindrical 10 of mold insert 15 also has tank filler sleeve 5 in notch.
As shown in Figure 5 and Figure 6, also comprise and coordinate with mold insert 15 rotor bearing installed, the outer ring 12 of rotor bearing is provided with inclined-plane, outer ring first 13 and inclined-plane, outer ring second 14; Inclined-plane, outer ring first 13 coordinates with the second inclined-plane 9 of mold insert 15 and abuts, and inclined-plane, outer ring second 14 coordinates with the first inclined-plane 1 of mold insert 15 and abuts.
