Abstract
The utility model discloses a motor rotor which comprises an output shaft and a magnet ring. An elastic jack catch is arranged at one end of the output shaft, and an output shaft gear is arranged at the other end of the output shaft. A limiting block is arranged on the root portion of the elastic jack catch. And the magnet ring is connected between the elastic jack catch of the output shaft and the limiting block in a clamping mode. The motor rotor is simple in structure, reduces requirements of mould accuracy, is convenient to process, improves production efficiency, and reduces production cost.
Description
Technical field
The utility model relates to a kind of rotor.
Background technology
Rotor by output shaft and magnet ring combine mainly processes through the inserts Shooting Technique at present.Add man-hour, earlier the processing powder metallurgical gear is pressed into powder metallurgical gear in the mould of plastic gear then as inserts, at last injection moulding processing plastic gear again.In the existing technology during injection moulding mould must fit like a glove with powder metallurgical gear as inserts, otherwise just have the surface of plastic covered to powder metallurgical gear, to having relatively high expectations of mould and die accuracy, production efficiency is low, cost is high.
The utility model content
The utility model technical problem to be solved provides a kind of rotor simple in structure, easy to process, enhances productivity, and reduces production costs.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provided is: a kind of rotor comprises output shaft and magnet ring; One end of said output shaft is provided with elastic card claw, and the other end is provided with output shaft gear; The root of said elastic card claw is provided with positive stop; Said magnet ring is connected between the elastic card claw and positive stop of output shaft.
The inwall of said magnet ring is provided with the claw groove; Said claw groove matches with the elastic card claw of output shaft.
After having adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model magnet ring is connected between the elastic card claw and positive stop of output shaft, and is simple in structure; Reduced requirement to mould and die accuracy; Easy to process, improved production efficiency, reduced production cost.
(2) the claw groove of the magnet ring of the utility model matches with the elastic card claw of output shaft; During assembling the elastic card claw of the output shaft claw groove along magnet ring is inserted in the endoporus of magnet ring; Magnet ring is connected between the elastic card claw and positive stop of output shaft; Effectively improved assembly precision, can prevent effectively that magnet ring and output shaft from relatively rotating simultaneously.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of output shaft and the magnet ring of the utility model when unassembled.
Label in the accompanying drawing is:
Embodiment
(embodiment 1)
See Fig. 1, the rotor of present embodiment comprises output shaft 1 and magnet ring 2.
One end of output shaft 1 is provided with elastic card claw 11, and the other end is provided with output shaft gear 12.The root of elastic card claw 11 is provided with positive stop 13.Magnet ring 2 is connected between the elastic card claw 11 and positive stop 13 of output shaft 1.The inwall of magnet ring 2 is provided with claw groove 21, and claw groove 21 matches with the elastic card claw 11 of output shaft 1.
During assembling, the elastic card claw 11 of the output shaft 1 claw groove 21 along magnet ring 2 is inserted in the endoporus of magnet rings 2.When the head of elastic card claw 11 passed magnet ring 2, an end of magnet ring 2 was fastened by the head of elastic card claw 11, and the other end is close to positive stop 13, thereby realized the axial restraint of magnet ring 2.And this moment, the middle part of the elastic card claw 11 of output shaft 1 will fall into the claw groove 21 of magnet ring 2, prevents that magnet ring 2 and output shaft 1 from relatively rotating.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
Claims (2)
1. a rotor is characterized in that: comprise output shaft (1) and magnet ring (2); One end of said output shaft (1) is provided with elastic card claw (11), and the other end is provided with output shaft gear (12); The root of said elastic card claw (11) is provided with positive stop (13); Said magnet ring (2) is connected between the elastic card claw (11) and positive stop (13) of output shaft (1).
2. a kind of rotor according to claim 1 is characterized in that: the inwall of said magnet ring (2) is provided with claw groove (21); Said claw groove (21) matches with the elastic card claw (11) of output shaft (1).
