Abstract
The utility model relates to a direct current motor convenient for being assembled, which belongs to the technical field of motor production and manufacture, and comprises a casing, and a front end cap and a rear end cap which are arranged on two ends of the casing, wherein a plurality of magnetic steels are evenly distributed on the inner wall of the casing, a circlip is arranged between adjacentmagnetic steels, and is in an elongated structure, the cross 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, a screw penetrates through the casing through a zone surrounded by the two first oblique portions and the cross portion of the circlip, thereby connecting the front end cap and the rear end cap. The direct current motor is convenient for assembling the casing, the front end cap and the rear end cap, can effectively utilize the space between adjacent magnetic steel, has compact structure, and can lower the manufacture cost of the motor.
Description
Technical field
The utility model relates to a kind of direct current machine of being convenient to assemble, and 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 direct current machine of being convenient to assemble 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 comprises casing and is located at the front end housing and the rear end cap at casing two ends, described casing inner wall is evenly distributed with several magnet steel, be provided with jump ring between the adjacent magnet steel, described jump ring 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, the oblique outside of symmetry, the end of described two first oblique portions extends to form two second oblique portions, and the zone that screw surrounds via two the first oblique portions and the transverse part of jump ring is run through casing front end housing and rear end cap are linked together.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.
