Abstract
A motor with one-step punch forming and easy-to-install end covers, a front end cover and a rear end cover are all provided with a bearing bowl with holes at one end, a small block extending inwards, a boss with holes at the other end, an end cover with a dent and a reverse fin, and four corners of a stator core are trimmed into concentric arcs matched with the inner diameter of the boss of the end cover. During the equipment, both ends lid boss cover is on the iron core, and under the indenture was just in time arranged in to the iron core four corners, by bolt, nut fastening, this utility model has end cover one-time stamping forming, uses manpower sparingly, material resources, management convenience, and economic benefits is high, and the position is accurate when the equipment does not have the mistake, and easy installation is favorable to guaranteeing product quality.
Description
The utility model belongs to motor type, relates generally to the improvement of standing electric fan with electric motor structure.
People know, and the stator of motor, rotor always are assembled in the particular shell.Usually standing electric fan is inequality with two sections shell mechanisms of motor, need with so not only mould investment increase of two mold machine-shapings, and the production management inconvenience, and be difficult to centering, assembling is inconvenient.
For overcoming the prior art existing problems, it is identical to seek a kind of two sections shells (hereinafter to be referred as end cap), and the one-shot forming of end cap energy, guarantees that the installation position heart is accurate, installs and is easy to motor, and the spy has proposed the utility model.
For finishing the proposed invention task, adopted following technical scheme:
1, front and rear cover is made same structure, be that front and rear cover all makes an end and has and can pass main shaft, hold bearing and oil cup with holes and the fastening bearing cap in stretch fritter, the other end has big boss with holes, and four holes are uniform on the boss, is pressed with the indenture that width and stator core foursquare arc length match in outer, four holes, and be provided with anti-wing in the lower edge of boss, make front and rear cover can use same mould, one time punching molded, need not deburring.
2, the isocentric circular arc that matches with end cap boss internal diameter is accomplished in four jiaos of stator cores, stator core can directly be enclosed within the end cap boss, and foursquare arc just placing on the boss under four sections indentures, accurate when guaranteeing to install to the heart, and easy to assembly.
Below in conjunction with embodiment the utility model is described in detail:
Fig. 1, the utility model structural representation;
Fig. 2, end cap boss with holes, indenture, anti-wing enlarged diagram;
Fig. 3, stator core cooperate schematic diagram with the end cap boss.
In Fig. 1, (1) main shaft, (2) bearing, (3) liner, (4) collar, (5) bearing cap, (6) packing ring, (7) rotor, (8) bolt, nut, (9) stator, (10) end cap, (11) cup, (12) stretch fritter in, (13) stator coil, (14) indenture, (15) anti-wing, (16) boss, (17) stator core.
As can be seen from Figure 1, this motor is symmetric figure, and its front and rear cover and assembly are all identical, and end cap (10) is by the sheet metal punch forming, an end have cup with holes (11) and in stretch fritter (12).Cup is made running in bearings, and supporting spindle is used.In stretch fritter and be positioned at the cup periphery, be slightly larger than on the concentric circumferences of bearing cap, establish 3~4 usually and get final product, when the end cap punch forming, stretch shape in this fritter is, during installation, fritter is withheld on bearing cap by hydraulic press.The other end of end cap has big boss with holes (16), four holes are uniform on the boss, be pressed with four sections indentures (14) (as shown in Figure 2) in the outer in hole, the foursquare arc of the width of four sections indentures and stator core matches on the boss, the height of boss is slightly less than half of stator core thickness, to guarantee leaving ventilation gap after the assembling.In addition, be provided with anti-wing (15) in the lower edge of boss, because anti-wing has solved the problem of Sheet Metal Forming Technology requirement reservation allowance, designed anti-wing not only can increase the rigidity of end cap, improve intensity, and need not the deburring processing, save trimming process step, make front and rear cover can use same mould, one time punching molded.The same with existing end cap, be provided with the mounting support bar in the side of end cap or introduce the hole that electric wire is used, and be provided with ventilation macropore and some assembling apertures in interior outer of stretching fritter, (not drawing among the figure), its size and quantity are decided by actual needs.
As can be seen from Figure 3, stator core is accomplished the isocentric circular arc that the boss internal diameter matches for four jiaos, and stator core can directly be enclosed within the end cap boss, and four jiaos just in time place on the boss under four sections indentures (14).
Above three figure of combination can find out, rotor (7) is installed on the main shaft (1), the main shaft two ends are by the bearing (2) in the cup that is contained in end cap (10) (11) supporting, and bearing is by liner (3), collar (4), stretch fritter (12) on bearing cap (5) and the end cap to compress, block the jail.Cup and bearing cap are formed the oil sealing cavity, are in the work of oil sealing shape to keep bearing.The boss of two end cap (16) is enclosed within on the stator core (17) that installs stator (9), under four jiaos of four sections indentures (14) that just in time place on the boss of stator core, fastening by bolt, nut (8), because the height of end cap boss is slightly less than stator core thickness half, thereby during fastening nut, can guarantee to press appropriateness, can reserve ventilation gap again, improve the thermal diffusivity of motor.
Therefore, improvements of the present utility model are that the motor front and rear cover is identical, and the end at end cap is provided with boss with holes, indenture and anti-wing, and stator core is accomplished the isocentric circular arc that matches with end cap boss internal diameter for four jiaos, all the other are identical with original product, promptly, improved installation quality guaranteeing to have improved processability under the constant situation of motor performance.
Through the advanced development probationary certificate, the novel performance of this usefulness is identical with former motor, can save a cover diel when producing but organize, the trimming process step after the punching out of minimizing end cap, and during installation, the position heart is accurate, is easy to assembled formation, more helps guaranteeing product quality.
This shows, the utlity model has following advantage:
1, owing to can save a mold, saved trimming process step and can save a large amount of human and material resources, convenient management, remarkable in economical benefits.
The position heart is accurate when 2, assembling, and installs easily, is conducive to guarantee the raising of product quality.
