Motor stator need carry out the encapsulating to the stator in production assembling process to the winding coil in the fixed stator can also play the insulation to the winding coil simultaneously, with the heat that the winding coil produced to functions such as casing conduction. In a traditional glue pouring method for a motor stator, glue is usually poured into the stator by gravity from the upper part of the motor stator, and the glue flows downwards between the stator and a base under the action of gravity. However, because the inner surface of the base is rough, the glue solution directly flows into the base and is easy to adhere to the base, the volume of the glue solution is reduced after being immobilized, the base is pulled, the deformation of the base is easily caused, and then the bearing cavity on the base is difficult to be matched with the bearing. In addition, follow-up needs are dismantled the base and are in order to maintain motor stator, because the base is in the same place with the colloid adhesion that the glue solution solidification back formed, greatly increased dismantles the degree of difficulty that gets off the base alone, is unfavorable for the later maintenance.
Referring to fig. 1 to fig. 3, in view of the above problems, the present invention provides an embodiment of a motor stator, which is configured with a glue filling rubber pad 200 on a base 110 to separate a glue filling glue from the base 110, so as to reduce the occurrence of the situation that the glue filling glue adheres to the base 110, and further avoid the deformation of the base 110 due to pulling of the solidified glue 140, and reduce the difficulty of subsequently detaching the base 110. The specific structure of the motor stator 100 will be described in detail below.
Referring to fig. 3 and 4, in an embodiment of the motor stator provided by the present invention, the motor stator 100 includes a housing and a glue-pouring cushion 200; the housing comprises a base 110 and a shell 120 arranged on the base 110, and the base 110 and the shell 120 enclose to form an accommodating cavity for mounting the stator assembly 130; the glue-pouring pad 200 is disposed on the base 110. Wherein, the inner surface of the base 110 is convexly provided with a bearing part 112 corresponding to the inner cavity 131 of the stator assembly 130; the rubber insert 200 is fitted around the outer periphery of the bearing portion 112.
Specifically, the base 110 and the shell 120 of the housing enclose to form an accommodating cavity; the stator assembly 130 of the motor stator 100 is arranged in the accommodating cavity, and the stator assembly 130 is located above the glue-pouring rubber mat 200 and is fixedly connected with the shell 120; the stator assembly 130 has an inner cavity 131 through which the spindle 400 passes for insertion into the bearing portion 112.
Referring to fig. 5 and 6, before the potting, the mandrel 400 is inserted through the inner cavity 131 of the stator assembly 130 and is inserted into the bearing portion 112 of the base 110, so that a space for installing the rotor 300 is formed at a position where the mandrel 400 is drawn out after the potting is completed. After the mandrel 400 is installed, the motor stator 100 may be potted. Here, two glue filling schemes may be used to fill the motor stator 100. One of the glue filling schemes is to perform gravity glue filling on the stator from the upper part of the motor stator 100, the glue flows downwards between the stator assembly 130 and the base 110 under the action of gravity, and after the glue filling is completed, the air bubble gap is exhausted by vacuumizing.
Another glue filling scheme is that a glue filling nozzle is arranged on the glue filling rubber mat 200, the glue filling nozzle penetrates through the shell, glue is filled into the glue filling rubber mat 200 through the glue filling nozzle, then the glue fills the bottom of the stator assembly 130 and the gap around the stator assembly 130 from bottom to top, and in the process of filling the gap, the air in the gap is upwards expelled by the glue. The two glue filling schemes can be selected alternatively, and are not particularly limited. Specifically, in the present embodiment, the latter embodiment is adopted, that is, a glue filling nozzle is disposed on the glue filling rubber pad 200 for feeding the glue solution into the glue filling rubber pad 200 from the outside to the inside.
During the encapsulating process, because encapsulating cushion 200 foreshadowing at the internal surface of base 110, encapsulating cushion 200 is smooth and have elasticity, encapsulating cushion 200 separates the internal surface interval of glue solution and base 110, and the glue solution in the encapsulating process can only fall on encapsulating cushion 200, and the glue solution is difficult to cross encapsulating cushion 200 and contacts base 110 to the glue solution is also difficult for gluing base 110, and then the condition that reducible encapsulating glue solution adhered base 110 appears. As for the shape and structure of the glue-pouring pad 200, it can be designed according to the inner surface structure of the base 110, and will be described in detail later.
The technical scheme of the utility model, through configuration encapsulating cushion 200 on motor stator 100's base 110 to utilize this encapsulating cushion 200 to part base 110 and the glue solution interval of encapsulating, thereby make the glue solution be difficult for adhering base 110, and then the condition that base 110 was adhered to reducible encapsulating glue solution appears. Accordingly, the glue is not adhered to the base 110, so that the glue is not easy to pull the base 110 when being solidified, the base 110 is prevented from being pulled and deformed, and the bearing part 112 on the base 110 can be matched with the bearing 330. In addition, the base 110 is not adhered to the glue 140 formed after the glue solution is cured, so that the base 110 can be easily detached from the shell 120, and the difficulty in detaching the base 110 is greatly reduced.
Referring to fig. 3, 4 and 7, in an embodiment, the base 110 has a groove 115 surrounding the outer circumference of the bearing portion 112; the glue-pouring pad 200 comprises a main body portion 210 embedded in the groove 115, and the main body portion 210 is configured with a glue-pouring groove 213. Specifically, the base 110 includes a bottom plate 111 and a connection portion 113 disposed along an outer periphery of the bottom plate 111; the upper surface of the bottom plate 111 is provided with a bearing portion 112, and a groove 115 is formed between the bearing portion 112 and the connecting portion 113.
Through embedding the main part 210 of the glue filling rubber mat 200 into the groove 115 of the base 110, the movement of the glue filling rubber mat 200 on the base 110 can be limited, so that the glue filling rubber mat 200 is not easy to move and shift. Because the main body part 210 is provided with the glue pouring groove 213, part of glue solution of glue pouring can be filled in the glue pouring groove 213, and the glue 140 formed after the part of glue solution is solidified is embedded in the groove 115 of the base 110 through the main body part 210 of the glue pouring cushion 200, so that the stability of the glue 140 installed on the base 110 can be enhanced; in addition, the stress of the colloid 140 can be dispersed, the excessive concentration of the stress is avoided, and the increased colloid 140 is not easy to break under the pulling action force.
Further, the main body 210 includes a bottom wall 211 attached to the bottom surface of the groove 115, and side walls 212 located at both sides of the bottom wall 211 and attached to the inner side surfaces of the groove 115; the bottom wall 211 of the main body 210 and the two side walls 212 thereof enclose a glue filling groove 213.
Specifically, in the longitudinal section of the glue-pouring pad 200, the bottom wall 211 of the main body portion 210 is U-shaped with the two side walls 212, so that the glue-pouring groove 213 is formed in the U-shape between the bottom wall 211 and the two side walls 212. Because the bottom wall 211 and the two side walls 212 of the main body portion 210 are attached to the surface of the groove 115, the glue-pouring cushion 200 is effectively fixed. Further, the volume of the potting groove 213 in the body 210 can be increased as much as possible.
Referring to fig. 5 and 6, according to any of the above embodiments, the bearing portion 112 of the motor stator 100 is configured with a bearing cavity 112a for mounting the bearing 330 of the rotor 300. During the glue filling process, the mandrel 400 needs to be inserted into the bearing portion 112 of the base 110 of the motor stator 100 to prevent the glue from falling into the bearing cavity 112 a; the spindle 400 has an insertion end 410 inserted into the bearing cavity 112a, and an abutting surface 420 located around the insertion end 410 and abutting against the top surface of the bearing portion 112 (i.e., the periphery of the opening of the bearing cavity 112 a). There may be a gap between the abutting surface 420 and the top surface of the bearing portion 112, so that the glue may penetrate through the gap and adhere to the top surface of the bearing portion 112 or the inside thereof during the glue filling process.
In view of this, in order to solve the above technical problem, in the present embodiment, the glue-pouring pad 200 further includes an inner pad 220 extending inward from the inner periphery of the main body portion 210, and the inner pad 220 is laid on the top surface of the bearing portion 112. Specifically, the inner spacer 220 extends radially inward at an upper end of one of the sidewalls 212 of the body portion 210.
When the mandrel 400 is installed, the mandrel 400 is inserted into the stator assembly 130 from top to bottom, the insertion end 410 is inserted into the bearing cavity 112a of the bearing portion 112, and the abutting surface 420 presses the inner pad 220 of the glue-pouring rubber pad 200 against the top surface of the bearing portion 112. This not only seals the gap between the abutting surface 420 of the stem 400 and the top surface of the bearing portion 112, but also prevents the adhesive from leaking and adhering to the top surface of the bearing portion 112 at this position. Moreover, the inner pad 220 is pressed by the mandrel 400, so that the inner edge of the glue filling rubber pad 200 is fixed and is not easy to displace in the glue filling process.
Referring to fig. 1 and 2, it is further contemplated that after the potting process is completed, the mandrel 400 is withdrawn and the rotor 300 is assembled to the original position where the mandrel 400 was installed to assemble the motor with the motor stator 100. Generally, the rotor 300 includes a body 310, an output shaft 320 connected to the body 310 and extending outward from the bearing portion 112, and a bearing 330 disposed on the output shaft 320. When assembled, the rotor 300 is installed in the inner cavity 131 of the stator assembly 130 of the motor stator 100, the output shaft 320 of the rotor 300 passes through the bearing cavity 112a of the bearing part 112 to the outside, and the bearing 330 of the rotor 300 is installed in the bearing cavity 112 a.
However, the bearing cavity 112a of the motor stator 100 and the bearing 330 of the rotor 300 are usually in clearance fit, which may cause two problems. One of the problems is that the outer race of the bearing 330 is easily rubbed and collided with the inner wall of the bearing chamber 112a during the operation of the rotor 300, thereby generating vibration and noise. Another problem is that dust or liquid in the external environment is easily introduced into the bearing cavity 112a, and then enters the interior of the stator assembly 130 through the gap, and finally adheres between the stator assembly 130 and the rotor 300, resulting in rusting, seizure, and the like.
Referring to fig. 2 to fig. 4, to solve the above problem, in the present embodiment, the bearing portion 112 has a bearing cavity 112 a; the inner diameter of the inner spacer 220 is smaller than the inner diameter of the bearing cavity 112 a. R in FIG. 41Expressed as the inner diameter, R, of the inner shim 2202Shown as the inner diameter of bearing cavity 112a, and thus has an R1＜R2. That is, the inner pad 220 protrudes inward from the opening peripheral edge of the bearing cavity 112 a. Therefore, after the bearing 330 of the rotor 300 is mounted in the bearing cavity 112a, the outer circumferential surface of the bearing 330 contacts and adheres to the inner gasket 220, so as to close the gap between the bearing 330 and the bearing cavity 112a, thereby preventing the outer ring of the bearing 330 from easily rubbing or colliding with the inner wall of the bearing cavity 112a, and reducing the generation of vibration and noise.
Furthermore, dust or liquid in the external environment is difficult to enter the stator assembly 130 from the bearing cavity 112a, so that the stator assembly 130 and the rotor 300 are prevented from being polluted, rusted, stuck and the like. In addition, in the glue filling process, the inner peripheral edge of the inner gasket 220 of the glue filling rubber pad 200 is attached to the outer circumference of the mandrel 400, so that the inner gasket 220 is extruded by the mandrel 400 along the axial direction, and the gap between the mandrel 400 and the bearing cavity 112a can be sealed, thereby preventing the glue from permeating into the bearing cavity 112 a.
Referring to fig. 2 to 4, according to any of the above embodiments, the base 110 is formed with a connecting portion 113 outside the groove 115 for connecting with the housing 120. The glue during the potting process may also adhere to the top surface of the connector 113 or leak out from the location where the connector 113 and the housing are connected. Therefore, optionally, the glue-pouring pad 200 further includes an outer pad 230 extending outward from the outer periphery of the main body portion 210, and the outer pad 230 is laid on the top surface of the connecting portion 113. The outer gasket 230 extends radially outward, particularly from the upper end of the sidewall 212 of the body portion 210 remote from the inner gasket 220. This prevents the adhesive from adhering to the top surface of the connection portion 113. In addition, the outer gasket 230 can be pressed and fixed on the top surface of the connecting portion 113 by the lower end of the housing 120, so that the outer edge of the glue-pouring pad 200 is fixed and is not easily displaced during the glue-pouring process.
Further, the top surface of the connection portion 113 is configured with a clamping step 114 for clamping the lower end of the housing 120, and the clamping step 114 has a first step surface 114a and a second step surface 114 b; the second step surface 114b is located inside the first step surface 114a and is higher than the first step surface 114 a; the outer pad 230 of the potting adhesive pad 200 is laid on the second step surface 114 b.
Specifically, the lower end of the housing 120 is engaged with the engaging step 114 of the base 110, and the outer pad 230 is pressed and fixed on the second step surface 114b of the engaging step 114, so that the potting adhesive 200 is fixed on the base 110. Therefore, the outer gasket 230 of the glue-pouring rubber mat 200 seals the connection position between the base 110 and the shell 120, and can reduce the leakage of glue at the connection position.
Referring to fig. 1 and 2, the present invention further provides an electric machine, which includes a rotor 300 and a motor stator 100, wherein the rotor 300 is installed in the inner cavity 131 of the stator assembly 130 of the motor stator 100 and is movably connected to the bearing portion 112 of the motor stator 100.

Therefore, the gap between the bearing 330 and the bearing cavity 112a can be blocked, the outer ring of the bearing 330 can be prevented from being easily rubbed or collided with the inner wall of the bearing cavity 112a, and the generation of vibration and noise can be reduced.
