Abstract
The utility model relates to a combined structure for slidingly assembling a stator punching sheet and a motor cylinder. The combined structure comprises a stator (1), buckle piece grooves (2) and a motor cylinder (4), wherein at least two positioning grooves (3) are formed in the outer wall of the stator (1) along the axial direction of the stator (1), the buckle piece grooves (2) and the positioning grooves (3) are evenly distributed on the outer wall of the stator (1) at intervals, the inner wall of the motor cylinder (4) is provided with a plurality of positioning bosses (5), and the positioning bosses (5) are matched with the positioning grooves (3); and the inner diameter of the stator (1) ranges from 63mm to 65mm, and the diameter of the circumference of the bottom part of a plurality of notches ranges from 84mm to 86.4mm. The combined structure has the advantages that: the structure is simple, the size of the notches is reduced, the copper consumption of the stator is significantly decreased, and the manufacturing cost of the stator is reduced; and the stator can be installed with the motor cylinder in a pressed manner through the outer diameter, and can realize the sliding assembly with the motor cylinder provided with the positioning bosses through the positioning grooves, thereby achieving dual purposes of the stator.
Description
Technical field
The utility model relates to machine field, particularly the combining structure of a kind of stator punching and machine barrel slidable fit.
Background technology
Motor is widely used in the various electric equipments of industrial production and life, existing motor has stator and rotor, position relationship classification by rotor and stator has two kinds: inner rotor type motor and external rotor electric machine, the rotor of inner rotor type motor is arranged in stator, and external rotor electric machine is that stator is arranged in rotor.Conventionally the end cap that inner rotor type motor has housing and is positioned at housing two ends, a cavity of housing and end cap besieged city, stator and rotor are arranged in cavity, and stator is fixedly mounted on housing inner side, traditional stator and housing employing interference fit, directly by stator press-loading in enclosure interior, its installation form is single, and installation difficulty is larger, in installation process, easily damage stator.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple in structure, low cost of manufacture and stator can realize the combining structure of dual-purpose stator punching and machine barrel slidable fit.
The purpose of this utility model is achieved through the following technical solutions: the combining structure of a kind of stator punching and machine barrel slidable fit, it comprises stator, the cramp groove arranging along stator shaft orientation and the machine barrel coordinating with stator, the cross section of described stator is cirque structure, the inner side of stator offers a plurality of notches on same circumference, along stator, axially on the outer wall of stator, offer at least two location notchs, on described machine tube inner wall, be provided with a plurality of positioning boss, positioning boss coordinates with location notch.
The cross section of described location notch is rectangle structure.
Described cramp groove and location notch are distributed on the outer wall of stator evenly and at intervals.
The inside diameter ranges of described stator is 63mm～65mm, and the diameter range of the circumference at the place, bottom of a plurality of notches is 84mm～86.4mm.
The utlity model has following advantage:
1, the utility model is along the equal location notch of its axially spaced-apart and cramp groove on the outer wall of stator, and it is simple in structure, and notch size decreases, and the copper consumption of stator significantly reduces, and reduces its manufacturing cost.
2, stator both can directly press-fit with machine barrel with its external diameter, can and realize slidable fit with the machine barrel of positioning boss with location notch again, had realized the dual-purpose of stator.
Accompanying drawing explanation
Fig. 1 is the structural representation of the assembling of stator and machine barrel;
Fig. 2 is the structural representation of stator;
Fig. 3 is the structural representation of machine barrel;
In figure: 1-stator, 2-cramp groove, 3-location notch, 4-machine barrel, 5-positioning boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, Figure 2 and Figure 3, the combining structure of a kind of stator punching and machine barrel slidable fit, it comprises stator 1, the cramp groove 2 axially arranging along stator 1 and the machine barrel 4 coordinating with stator 1, the cross section of described stator 1 is cirque structure, the inner side of stator 1 offers a plurality of notches 6 on same circumference, along the axial of stator 1, offer at least two location notchs 3 on the outer wall of stator 1, on described machine barrel 4 inwalls, be provided with a plurality of positioning boss 5, positioning boss 5 coordinates with location notch 3.
As shown in Figure 2, the cross section of described location notch 3 is rectangle structure, and cramp groove 2 is distributed on the outer wall of stator 1 evenly and at intervals with location notch 3.
The inside diameter ranges of described stator 1 is 63mm～65mm, and the diameter range of the circumference at the place, bottom of a plurality of notch 6 is 84mm～86.4mm, and the sectional area of notch 6 is less than the sectional area of traditional notch 6, reduces copper consumption, saves cost of manufacture.
