The objective of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of dust seal type AC permanent-magnet synchronous electric main shaft.Dust seal of the present invention is good, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: the synchronous electric main shaft of a kind of dust seal type AC permanent-magnet, comprise shell, the p-m rotor assembly, stator module, rotating shaft, preceding gland and rear pressing cover, the front and back end of described shell is respectively arranged with front-end bearing pedestal and rear bearing block, gland is positioned at the outer end of front-end bearing pedestal before described, described rear pressing cover is positioned at the outer end of rear bearing block, described rotating shaft setting in the enclosure, and described rotating shaft is respectively by being arranged on fore bearing and the location of the rear bearing on the rear bearing block on the front-end bearing pedestal, described p-m rotor assembly is arranged on outer casing inner wall, described stator module is installed on the rotating shaft, and the position of described p-m rotor assembly and stator module is corresponding, the front end of described rotating shaft gland in the past stretches out, the rear end of described rotating shaft is provided with encoder, be provided with between locking nut that moving axially of fore bearing limited and described locking nut and preceding gland gapped between described front-end bearing pedestal and the preceding gland, it is characterized in that: be provided with a plurality of annular grooves on the described locking nut and around described one week of locking nut, be provided with high temperature cloth in the described groove, be provided with the high temperature cloth chuck that high temperature cloth is carried out clamping in the described groove.
The above-mentioned synchronous electric main shaft of a kind of dust seal type AC permanent-magnet, described high temperature cloth are a kind of in Teflon high temperature varnished cloth, Teflon adhesive tape and the Kevlar tetrafluoro screen cloth.
The present invention compared with prior art has the following advantages: the synchronous electric main shaft of a kind of dust seal type AC permanent-magnet of the present invention, by a plurality of annular grooves on the locking nut, and high temperature cloth is set in groove, high temperature cloth is very soft when being heated, it forms the same thing of similar hairbrush of a lot of at the gap location of locking nut and preceding gland, it contacts with preceding gland constantly, and these multi-turn high temperature cloth are just formed a sealing that the labyrinth is the same, the very effective dustproof effect that plays.Good seal performance of the present invention, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
