Abstract
The utility model relates to a rotor of a DC motor with a bush, which is composed of a shaft, an iron core, a front sleeve barrel, a rear sleeve barrel and a commutator, wherein, the shaft passes through the iron core, the front sleeve barrel and the rear sleeve barrel are respectively arranged at both ends of the iron core, the commutator is installed near the front sleeve barrel, and the iron core is completely wraped by plastic. Because the iron core is completely wraped by the plastic, and plastic used for insulation is arranged between the iron core and the shaft; insulation effect is favorable. Meanwhile, the utility model does not need to be respectively provided with a slot for insulation and an insulation end plate, but the utility model is completely wraped by the plastic. Therefore, the utility model has the advantages of simple structure, simple machining and high productive efficiency.
Description
1. technical field
The utility model relates to a kind of motor component, especially a kind of DC electromotor with brush rotor.
2. background technology
Existing its insulation system of DC electromotor with brush rotor generally is that internal circular surfaces, side, the groove face at iron core adopts the electrostatic coating insulating material, or adopting slot liner to add insulating end plate covers, and the insulation effect of electrostatic coating insulating material is not good enough and occur crackle easily; And that slot liner adds structural manufacturing process complexity, production efficiency that insulating end plate covers is low; Simultaneously, the iron core of above-mentioned two kinds of traditional structures and between centers all do not have insulation, and leaky takes place on axle easily.
3. summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, handling ease, production efficiency height, DC electromotor with brush rotor that insulation effect is good are provided.
The technical scheme that realizes the utility model purpose is: the utility model is made up of axle, iron core, front sleeve, back sleeve and commutator, and axle passes iron core, and forward and backward sleeve branch is located at the iron core two ends, the forward sleeve setting of commutator, and iron core is wrapped up fully by plastics.
Good effect of the present utility model is: because iron core is wrapped up fully by plastics, iron core and between centers also have plastic insulation, and therefore, its insulation effect is good; Simultaneously, it need not to establish slot liner and insulating end plate respectively, but once wraps entirely with plastics, so it is simple in structure, handling ease, production efficiency height.
4. description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the cross sectional representation of iron core in the utility model.
5. embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in drawings, the utility model is made up of axle 5, iron core 3, front sleeve 2, back sleeve 4 and commutator 1, and axle 5 passes iron core 3, and forward and backward sleeve was located at iron core 3 two ends in 2,4 minutes, and commutator 1 forward sleeve 2 is provided with, and iron core 3 is wrapped up fully by plastics 6.When the utility model is manufactured in processing, in advance iron core 3 is carried out plasticly entirely, make iron core 3 internal circular surfaces, end face and groove face all be enclosed with plastics 6, then axle 5 is compressed into 3 li of iron cores, be pressed into forward and backward sleeve 2,4 again, load onto commutator 1 at last.
