In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a rotor pressing mechanism, which comprises a sheath and a pressing plate, wherein the sheath is made of non-metallic materials, and the pressing plate is used for connecting an external rotating shaft and is matched with a rotor sleeved on the rotating shaft to wrap the rotating shaft; the outer side wall of the pressing plate is provided with first threads, the inner side wall of the sheath is provided with second threads, the first threads are screwed with the second threads, and the sheath is used for being matched with the rotor to wrap the pressing plate.
Further, the sheath is made of zirconia or silicon carbide.
Further, the pressing plate is made of a metal material.
Furthermore, the pressing plate is provided with a plurality of screw holes, and the screw holes are used for installing screws so that the pressing plate is connected with an external rotating shaft.
Further, the sheath is provided with an inner hole, the second thread is arranged on the inner side wall of the inner hole, and the volume of the inner hole is larger than that of the pressing plate.
Furthermore, one end of the sheath, which is used for abutting against the external rotor, is provided with a compensation hole.
Furthermore, the two sides of the sheath are respectively provided with a connecting hole.
The utility model has the advantages that: the utility model discloses a clamp plate and rotor cooperation realize the parcel to the pivot to sheath and clamp plate threaded connection's that make through the nonmetal mode, realized the parcel to the clamp plate, thereby let the pivot that the metal was made can not take place to contact with the material, avoided the material to receive metal contamination.
Drawings
Fig. 1 is a schematic view of the present invention in a use state.
Reference numerals: the novel motor rotor comprises a rotor body, a stator, a rotor, a rotating shaft, a first thread, a second thread, a screw hole, an inner hole, a compensation hole and a connecting hole, wherein the rotor comprises 1 part of a sheath, 2 parts of a pressing plate, 3 parts of a rotor, 4 parts of a rotating shaft, 5 parts of a first thread, 6 parts of a second thread, 7 parts of.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the rotor pressing mechanism provided by the present invention comprises a sheath 1 and a pressing plate 2, wherein the sheath 1 is made of a non-metallic material, and the pressing plate 2 is used for connecting an external rotating shaft 4 and is used for wrapping the rotating shaft 4 in cooperation with a rotor 3 sleeved on the rotating shaft 4; the outer side wall of the pressing plate 2 is provided with first threads 5, the inner side wall of the sheath 1 is provided with second threads 6, the first threads 5 are screwed with the second threads 6, and the sheath 1 is used for being matched with the rotor 3 to wrap the pressing plate 2.
In actual use, the utility model is matched with the rotating shaft 4 and the rotor 3 for use, and the sheath 1 is made of non-metallic materials such as zirconia or silicon carbide, which can avoid metal pollution to materials; in order to ensure strength, the pressure plate 2 is made of a metal material. And when the installation, because rotor 3 overlaps in pivot 4, consequently only the front end of pivot 4 leaks out, come the front end of pivot 4 by clamp plate 2 to cover this moment, and make sheath 1 install on clamp plate 2 through first screw thread 5 and the cooperation of second screw thread 6, let sheath 1 come to cover clamp plate 2 promptly, thereby make the part of rabbling mechanism and material contact make by non-metallic material, avoided the metal to get into in the material and pollute because of wearing and tearing and the granule that drops.
Furthermore the utility model discloses a direction of first screw thread 5 and second screw thread 6, all opposite with the rotation direction of pivot 4 to avoided pivot 4 to make first screw thread 5 and second screw thread 6 take place to rotate and part at the rotation in-process, guaranteed the utility model discloses a reliability.
In this embodiment, the pressing plate 2 is provided with a plurality of screw holes 7, and the screw holes 7 are used for installing screws so that the pressing plate 2 is connected with the external rotating shaft 4, thereby ensuring the stability of the connection between the pressing plate 2 and the rotating shaft 4 and further avoiding the falling of the sheath 1 connected with the pressing plate 2 in a threaded manner.
In this embodiment, the sheath 1 is provided with an inner hole 8, the second thread 6 is arranged on the inner side wall of the inner hole 8, and the volume of the inner hole 8 is larger than that of the pressing plate 2. Through letting 8 volumes in the hole be greater than clamp plate 2 volumes, let leave certain clearance between clamp plate 2 and the sheath 1 and cushion, be favorable to promoting the utility model discloses a life.
In this embodiment, the end of the sheath 1, which is used for abutting against the external rotor 3, is provided with a compensation hole 9 for compensating the volume expanded due to heat generation when heat is generated for a long time.
