Abstract
The utility model relates to a circlip structure for magnetic steel positioning, which belongs to the technical field of motor production and manufacture. The circlip is in an elongated structure, thecross section of the circlip comprises a cross portion, two ends of the cross portion are symmetrically and aslant extended towards the inner side to form two first oblique parts, and the end portions of the two first oblique parts are symmetrically and aslant extended towards the outer side to form two second oblique parts. The circlip structure is convenient for a casing to be assembled with afront end cap and a rear end cap, can effectively utilize space between adjacent magnetic steel, has compact structure, can lower manufacture cost of the motor, solves the problems in the prior art that the distance requirement between adjacent magnetic steel is bigger, or a screw can not penetrate through the circlip, thereby causing bigger casing volume, high manufacture cost of the motor and the like.
Description
Technical field
The utility model relates to a kind of jump ring structure that is used for the magnet steel location, belongs to the technical field that motor is manufactured.
Technical background
Magnet steel positions by the jump ring between adjacent magnet steel in motor case usually, and then by the glue bonding, the front end housing at casing two ends and rear end cap then link together by screw and the casing that runs through casing between magnet steel and the casing inner wall.Existing jump ring requires bigger to the spacing between the adjacent magnet steel, otherwise will cause screw to pass in the middle of jump ring, thereby has caused the casing volume bigger, and the manufacturing cost of motor is than problems such as height.
Summary of the invention
The utility model purpose is to provide a kind of be convenient to casing and front end housing and rear end cap assembling, can effectively utilize the space between the adjacent magnet steel, compact conformation, can reduce the jump ring structure that is used for the magnet steel location of the manufacturing cost of motor, solved the bigger of prior art existence to the requirement of the spacing between the adjacent magnet steel, otherwise will cause screw to pass in the middle of jump ring, thereby cause the casing volume bigger, the manufacturing cost of motor is than problems such as height.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it is strip structure, the cross section of jump ring comprises transverse part, the oblique inboard of symmetry, described transverse part two ends extends to form two first oblique portions, and the oblique outside of symmetry, end of described two first oblique portions extends to form two second oblique portions.After jump ring assembling magnet steel, jump ring of the present utility model can make full use of the space between the adjacent magnet steel, passes and be convenient to screw, thereby makes the structure of motor more compact, and reduced the manufacturing cost of motor.
As preferably, the angle between the described first oblique portion and the transverse part is 50 °-70 °, the angle between the first oblique portion and the transverse part is controlled in the suitable scope, thereby screw can be passed easily.
As preferably, the angle between the described first oblique portion and the second oblique portion is 95 °-115 °.
As preferably, the distance L between the junction of described two first oblique portions and two second oblique portions is the 2/5-4/5 of the length M of transverse part.
Therefore, the utlity model has and be convenient to casing and front end housing and rear end cap assembling, can effectively utilize the space between the adjacent magnet steel, compact conformation can reduce the characteristics such as manufacturing cost of motor.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figures 2 and 3, jump ring 1 is strip structure, the cross section of jump ring 1 comprises transverse part 2, the oblique inboard of symmetry, two ends of transverse part 2 extends to form two first oblique portions 3, angle β between the first oblique portion 3 and the transverse part 2 is 63 °, the oblique outside of symmetry, end of two first oblique portions 3 extends to form two second oblique portions 4, angle between the first oblique portion 3 and the second oblique portion 4 is 105 °, distance L between the junction of two first oblique portions and two second oblique portions is 13mm, the 19mm of the length M of transverse part.
As shown in Figure 1, four magnet steel 5 are evenly distributed on the inwall of casing 6, fixing between magnet steel 5 and the casing 6 by the glue bonding, between the adjacent magnet steel 5 jump ring 1 is set, the end of magnet steel 5 circumferencial directions is engaged between the first oblique portion 3 and the second oblique portion 4 of jump ring 1, and in the zone 7 that the two first oblique portions 3 and the transverse part 2 of jump ring 1 surrounds, screw is passed through easily, thereby made full use of the space between the adjacent magnet steel.
Claims (4)
1, a kind of jump ring structure that is used for the magnet steel location, be strip structure, it is characterized in that: the cross section of jump ring comprises transverse part, and the oblique inboard of symmetry, described transverse part two ends extends to form two first oblique portions, and the oblique outside of symmetry, end of described two first oblique portions extends to form two second oblique portions.
