Abstract
The air-gap setting process for motor is characterized by that after the motor rotor is mounted in the bore of motor stator, three air-gap setting stopping pieces which are identical in form and size are inserted into the air-gaps between the motor stator bore and excircle of motor rotor, and their space is 120 deg., and after the motor rotor is fixed, those air-gap setting stopping pieces are taken out from the motor. The invented stopping piece is easy to manufacture, low in cost, and the motor installation is labour-saving and time-saving.
Description
The present invention relates to a kind of air gap positioning technology of motor mounting technology, particularly a kind of motor.
In the motor assembling process, the motor gas-gap positioning process has various, as U.S. Pat 4590688 employings are rotor harness construction from parts, circle is shown off in the rotor harness, and is furnished with center pole, its drum diameter is equal to or less than the stator core internal diameter, and center pole penetrates in the dead eye when end cap and stator assembling.When harness is positioned at stator hole, center pole is positioned at dead eye, and stator and end cap attaching have just guaranteed the consistency of dead eye and stator hole concentricity when firm.Simultaneously, when taking out harness, formed fixedly air gap between the rotor.What U.S. Pat 3755889 adopted is caulking iron, and its caulking iron is formed a shim family by a plurality of shims by central shaft, and caulking iron is put into stator, rotor is put into again, and after the air gap between rotor is fixing, caulking iron integral body is shifted out again.And for example U.S. Pat 3719988 is to adopt conducting element to make its air gap location by the principle of expanding with heat and contract with cold.More than three kinds of complex technical process, caulking implement manufacture all more complicated, cost, cost are also all than higher.
The object of the present invention is to provide a kind of technology simple, caulking implement is easy, the air gap positioning technology that the cost cost is low.
The object of the present invention is achieved like this:
Motor includes front end housing assembling, stator, rear end cap assembling, rotor, when assembling motor, when rotor being installed in the stator behind the thorax, the air gap place of thorax and rotor cylindrical inserts three shapes, big or small identical air gap location patch in motor stator, 120 ° at interval of three patches, after the rotor assembling and positioning, again air gap is located patch and from motor, take out.
The present invention has been owing to adopted above-mentioned process, and its caulking implement promptly locatees patch and be convenient to manufacture, and the cost cost is low, so technology economizes merit, saves time, and technical process is easy.
Providing specific embodiment below in conjunction with accompanying drawing further specifies and the present invention seeks to how to realize.
Fig. 1 is motor overall structure figure;
Fig. 2 is the plane graph of front end housing assembling;
Wherein: 1, rear end cap assembling; 2, rotor; 3, stator; 4, rivet; 5, packing ring: 6, front end housing assembling; 7, positioning sleeve; 8, packing ring; 9, patch; 10, ventilation hole; 14, pilot hole.
Fig. 3 a patch front view, Fig. 3 b is the patch end view.
Wherein 11, intermediate plate; 12, inserted sheet 13, rivet;
As shown in Figure 1, 2, motor includes front end housing assembling (6), stator (3), rear end cap assembling (1), rotor (2).At first rotor (2) is inserted in positioning sleeve (7), and adjustment packing ring (8), guarantee the armature spindle spacing, because the electric machine structure of present embodiment adopts rivet to connect, so again rivet (4) is penetrated four pilot holes (14) of rear end cap assembling (1) and stator (3), to put into the thorax of stator (3) by the rotor assembling that positioning sleeve (7) and rotor (2) are formed, and three location patches (9) are inserted respectively in the air gap of the interior thorax of stator (3) and rotor (2) cylindrical, 120 ° at interval of three location patches (9), front end housing assembling (6) then is installed, four pilot holes are corresponding with four pilot holes (14) on the stator on its end cap, three patches (9) expose from the ventilation hole (10) of front end housing assembling (6), adjust three location patches (9), until three patches (9) elasticity unanimity, at this moment motor is put into the riveter riveting, from the good motor of riveting, taken out patch (9) behind the riveting.
Electric machine structure also can adopt bolt to connect or other type of attachment in addition.
Patch (9) is made of intermediate plate (11), inserted sheet (12), rivet (13) as shown in Figure 3, and its inserted sheet shape is a microscler thin slice wide at the top and narrow at the bottom, and there is certain chamfering the junction wide at the top and narrow at the bottom of inserted sheet in the present embodiment (13).Intermediate plate (11) and rivet (13) they are to take out from motor for the ease of patch (9), also can uneasy clamping sheet (11) and rivet (13), directly inserted sheet (12) is used as patch (9).
Claims (4)
1, a kind of air gap positioning technology, be a kind of rotor technology consistent that guarantees when motor is installed with the motor stator concentricity, motor includes front end housing assembling, stator, rear end cap assembling, rotor, it is characterized in that when assembling motor, when rotor being installed in the stator behind the thorax, the air gap place of thorax and rotor cylindrical inserts three shapes, big or small identical air gap location patch in motor stator, 120 ° at patch interval, three location, after the rotor assembling and positioning, again air gap is located patch and from motor, take out.
2, air gap positioning technology according to claim 1 is characterized in that described location patch is a microscler thin slice wide at the top and narrow at the bottom.
