Abstract
The utility model provides a prevent that circle nut is not hard up card dead structure rotor, which comprises a rotating shaft, the rotor core who sets up rotor end plate at the epaxial both ends of commentaries on classics, set gradually at the rotor clamping ring of the wherein one end of pivot, lock washer and circle nut for the circle nut, the bearing of setting at the pivot both ends, its characterized in that pivot wherein is provided with the changeover portion between the screw thread section of connecing circle nut soon and fixing bearing's the bearing canned paragraph, the diameter of this changeover portion is less than the diameter of screw thread section, and simultaneously, the diameter of this changeover portion is greater than the diameter of bearing canned paragraph, the length of this changeover portion is greater than the thickness of circle nut. Compared with the application technology, the utility model, have and avoid round nut pine to take off the back card and make the bearing can not pivoted advantage on the bearing.
Description
Technical Field
The utility model relates to a motor technology.
Background
The permanent magnet synchronous motor rotor is used as a rotating mechanism supported by a left bearing and a right bearing, and threads are loosened during rotation, so that the thread structures on the rotor need to adopt anti-loosening measures.
At present, the matching section of the round nut on the rotor shaft of the permanent magnet synchronous motor is full thread, and the round nut is prevented from loosening through deformation of the stop washer for the round nut. However, in case of special situations such as missing installation of the stop washer, deformation of the stop washer and the like, the round nut is loosened, the rotor core is scattered and lengthened in the axial direction after the loosening, the round nut is abutted against the right-end bearing, the rotation of the round nut is limited due to the fact that the round nut is in full-thread fit with the rotor shaft, the rotation of the bearing is limited while the round nut is abutted against the bearing, and finally the motor rotor cannot rotate and is locked. If the locking fault occurs when the automobile runs at a high speed, accidents such as serious traffic accidents can happen due to instant locking of wheels.
Disclosure of Invention
The utility model aims at providing an it prevents that round nut not hard up card of dead structure rotor makes the bearing can not pivoted to block on the bearing to avoid round nut pine to take off the back card.
The utility model discloses a realize like this: the rotary shaft comprises a rotary shaft, rotor iron cores arranged at two ends of the rotary shaft and provided with rotor end plates, rotor pressing rings sequentially arranged at one end of the rotary shaft, a stop washer and a round nut for the round nut, and bearings arranged at two ends of the rotary shaft.
Like this, in case the round nut comes out from the screw thread section pine, because the diameter of changeover portion is less than the diameter of screw thread section, in case the round nut gets into the changeover portion, will be in the free rotation state, even touch the bearing, also can only rotate under the drive of bearing, and can not block the bearing, make the bearing can not rotate.
Compared with the application technology, the utility model, have and avoid round nut pine to take off the back card and make the bearing can not pivoted advantage on the bearing.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in the figure, the utility model discloses a pivot 1, the setting has rotor core 3 of rotor end plate 2 at the both ends in pivot 1, set gradually at the rotor clamping ring 4 of pivot 1 wherein one end, lock washer 5 and round nut 6 for the round nut, the setting is at the bearing 7 at pivot 1 both ends, its special character lies in that the pivot 1 wherein one end connect soon the screw thread section 1a of round nut 6 and be provided with changeover portion 1c between the bearing canned paragraph 1b of fixing bearing 7, this changeover portion 1 c's diameter is less than screw thread section 1 a's diameter, and simultaneously, this changeover portion 1 c's diameter is greater than bearing canned paragraph 1 b's diameter, this changeover portion 1 b's length is greater than round nut 6's thickness.
Claims (1)
