Description

Technical Field

[0001] The utility model relates to the field of stator winding packages, in particular to a stator winding package structure. Background Art

[0002] The coils in the stator winding package will form a magnetic field, which will form a rotating magnetic field when superimposed on each other. The magnetic fields are superimposed on each other to form a strong magnetic field. When the motor is connected to the power supply, the wires in the winding package will form a magnetic field due to the current in the wires. This magnetic field is constantly converted and then interacts with the rotor to generate the torque required by the motor to make the motor work normally. The motor is widely used, so the stator winding package is also crucial.

[0003] At present, the existing stator winding package is mostly installed by bolt installation. When placing the stator winding package in the lower motor casing, the stator winding package is first placed horizontally in the lower motor casing, and then the threaded holes on the outer wall of the stator winding package are matched with the threaded grooves at the end of the lower motor casing, and the stator winding package is fixed with bolts, so that when the motor is in use, the stator winding package can be stably fixed on the inner wall of the lower motor casing, so that the motor can work better.

[0004] However, the above-mentioned stator winding package still has certain shortcomings, because it is fixed to the lower motor casing by bolts, and the fixing structure of the stator winding package and the inner wall of the lower motor casing is relatively tight, so it is necessary to manually align the threaded holes on the outside of the stator winding package after placement, and it is necessary to use some items such as hammers and pliers to assist in aligning the stator winding package through vibration. This process is relatively cumbersome and takes a long time, affecting work efficiency. Therefore, it is urgently needed to improve the existing stator winding package installation. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a stator winding structure to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stator winding package structure, comprising a stator winding package main body, wherein the stator winding package main body is fixed in a lower motor casing, and the lower motor casing and the upper motor casing are detachably composed, and a second through hole for bolt installation is provided at the connection between the upper motor casing and the lower motor casing, a fixing ring is fixedly installed on the outer wall of the stator winding package main body, and a mounting frame for fixing the stator winding package main body is fixedly installed on the outer wall of the fixing ring, and a protrusion is fixedly installed on the outer wall of the end of the mounting frame, a first through hole is provided at the end of the mounting frame for fixing to the end of the lower motor casing, and a support block for supporting the stator winding package main body is fixedly installed on the inner wall of the lower motor casing.

[0007] By adopting the above technical solution, under the action of the mounting frame, when the stator winding body is installed in the lower motor casing, as the stator winding is moved, the mounting frame gradually squeezes the inner wall of the lower motor casing, so that the stator winding is better fixed in the lower motor casing. Under the action of the protrusion and the first through hole, the inclined surface of the outer wall of the protrusion cooperates with the inclined surface of the outer wall of the second through hole, so that the first through hole at the end of the mounting frame is aligned with the second through hole at the end of the lower motor casing. During the installation of the upper motor casing and the lower motor casing, the stator winding can be installed together. Compared with the method of aligning the holes by knocking on the lower motor casing, the more cumbersome installation steps are reduced, thereby making it more convenient for workers to install and improving work efficiency.

[0008] The utility model is further configured that the mounting frame is designed to be gradually inclined outward, and a plurality of mounting frames are symmetrically installed on the outer wall of the fixing ring.

[0009] By adopting the above technical solution and the inclined design of the mounting frame, when the stator winding body moves into the lower motor casing, the interior of the lower motor casing will squeeze the mounting frame, so that the mounting frame exerts the same force on the inner wall of the lower motor casing. Under the same force of the mounting frame, the stator winding body can be better fixed in the lower motor casing.

[0010] The utility model is further configured such that the edge of the end of the second through hole is designed as a bevel, and the edge of the outer wall of the end of the first through hole is designed as a bevel corresponding to the second through hole.

[0011] By adopting the above technical solution, under the guidance of the inclined surface of the second through hole, when the mounting frame moves toward the end of the lower motor housing, it is convenient to align and fix the first through hole at the end of the mounting frame with the second through hole, thereby reducing the steps of aligning the stator coil body with the lower motor housing.

[0012] The utility model is further configured that a sealing ring is provided at the connection between the upper motor housing and the lower motor housing, and the mounting frame is made of elastic metal.

[0013] By adopting the above technical solution, when the mounting frame moves into the lower motor casing along with the stator winding body, the mounting frame is elastically set so that while the inner wall of the lower motor casing squeezes the mounting frame, the mounting frame generates a relative force, thereby better fixing the stator winding body in the lower motor casing.

[0014] The utility model is further configured such that the center of the first through hole and the center of the second through hole are on the same vertical line, and a plurality of support blocks are symmetrically installed on the inner wall of the lower motor housing.

[0015] By adopting the above technical solution and setting the number of support blocks, when the stator winding package body moves into the lower motor housing, the support blocks will support the stator winding package body, thereby better fixing the stator winding package body in the lower motor housing.

[0016] The utility model is further configured that the outer wall of the end of the stator winding body is fixedly mounted with electric wires, and the outer wall of the end of the stator winding body is fixedly mounted with a protection frame for protecting the electric wires, and the protection frame is located on one side of the electric wires.

[0017] By adopting the above technical solution, when installing the stator winding body 1, the wires 9 may be adjusted, which may cause the wires to fall off or break due to the loose connection between the wires and the stator winding body. By setting the protective frame, the wires are wound around the protective frame, thereby effectively protecting the connection between the wires and the end of the stator winding body, making it difficult for the wires to be pulled off or fall off.

[0018] The utility model is further configured that a plurality of protection frames are installed at equal angles on the outer wall of the stator coil body.

[0019] By adopting the above technical solution, since there may be more than one wire at the end of the stator coil body, the protection frame will change with the number of wires, ensuring that the protection frame protects each wire.

[0020] The utility model is further configured that the protection frame is made of elastic rubber.

[0021] By adopting the above technical solution, since the wires need to be bent when they are installed, the material of the protection frame can protect the ends of the wires without affecting the normal bending of the wires, making the protection frame practical.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a mounting frame, a protrusion, and a first through hole. Under the action of the mounting frame, when the stator winding body is installed in the lower motor casing, as the stator winding body moves, the mounting frame gradually squeezes the inner wall of the lower motor casing, so that the stator winding body is better fixed in the lower motor casing. Under the action of the protrusion and the first through hole, the inclined surface of the outer wall of the protrusion cooperates with the inclined surface of the outer wall of the second through hole, so that the first through hole at the end of the mounting frame is aligned with the second through hole at the end of the lower motor casing. During the installation of the upper motor casing and the lower motor casing, the stator winding body can be installed together. Compared with the method of aligning the holes by knocking on the lower motor casing, the more cumbersome installation steps are reduced, thereby making it more convenient for workers to install and improving work efficiency.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1

[0035] A stator winding structure, such as Figure 1 - Figure 5 As shown, it includes a stator winding package body 1, which is fixed in a lower motor housing 101, and the lower motor housing 101 and the upper motor housing 102 are detachably composed, and a second through hole 7 for bolt installation is opened at the connection between the upper motor housing 102 and the lower motor housing 101.

[0036] Specifically, a fixing ring 2 is fixedly installed on the outer wall of the stator winding package body 1, and a mounting frame 3 for fixing the stator winding package body 1 is fixedly installed on the outer wall of the fixing ring 2. When the stator winding package body 1 moves into the lower motor casing 101, the mounting frame 3 moves downward synchronously, so that the mounting frame 3 obtains a sliding force, so that the mounting frame 3 contacts the end of the lower motor casing 101. When the upper motor casing 102 and the lower motor casing 101 are installed, the mounting frame 3 is installed together, so that the stator winding package body 1 is fixed in the lower motor casing 101, and a protrusion 4 is fixedly installed on the outer wall of the end of the mounting frame 3. Under the action of the protrusion 4, when the mounting frame 3 contacts the end of the lower motor casing 101, the mounting frame 3 is better aligned with the second through hole 7 at the end of the lower motor casing 101, so that the stator winding package body 1 is prevented from being stuck in the stator winding package body 1 under the action of the mounting frame 3. After placement, a step of manually rotating the stator winding package body 1 is required. A first through hole 5 for fixing to the end of the lower motor casing 101 is opened at the end of the mounting frame 3. When the stator winding package body 1 moves into the lower motor casing 101, the mounting frame 3 moves downward synchronously, so that the first through hole 5 at the end of the mounting frame 3 is aligned with the second through hole 7 at the end of the lower motor casing 101. Therefore, when the upper motor casing 102 and the lower motor casing 101 are installed, the mounting frame 3 can be fixed synchronously, so that the stator winding package body 1 is fixed in the lower motor casing 101, and a support block 6 for supporting the stator winding package body 1 is fixedly installed on the inner wall of the lower motor casing 101. When the stator winding package body 1 moves into the lower motor casing 101, when it moves down to a suitable position, the support block 6 supports the end of the stator winding package body 1, so that the stator winding package body 1 is better fixed in the lower motor casing 101.

[0037] See also Figure 1 - Figure 5 The mounting bracket 3 is designed to be gradually inclined outward. Through the inclined design of the mounting bracket 3, when the stator winding package body 1 moves into the lower motor casing 101, the interior of the lower motor casing 101 will squeeze the mounting bracket 3, so that the mounting bracket 3 exerts the same force on the inner wall of the lower motor casing 101. Under the same force of the mounting bracket 3, the stator winding package body 1 can be better fixed in the lower motor casing 101, and multiple mounting brackets 3 are symmetrically installed on the outer wall of the fixing ring 2. Through the arrangement of multiple mounting brackets 3, when the stator winding package body 1 moves into the lower motor casing 101, it has multiple relative forces on the inner wall of the lower motor casing 101, which can more effectively fix the stator winding package body 1 in the lower motor casing 101.

[0038] See also Figure 1 - Figure 5The edge of the end of the second through hole 7 is designed as a bevel. Under the guidance of the bevel of the second through hole 7, when the mounting frame 3 moves toward the end of the lower motor housing 101, it is convenient to align and fix the first through hole 5 at the end of the mounting frame 3 with the second through hole 7, thereby reducing the steps of aligning the stator winding package main body 1 with the lower motor housing 101, and the edge of the outer wall of the end of the first through hole 5 is designed as a bevel corresponding to the second through hole 7. Through the guidance of the bevel, the alignment efficiency of the first through hole 5 and the second through hole 7 is further improved. When the upper motor housing 102 and the lower motor housing 101 are installed, the mounting frame 3 is fixed synchronously, so that the stator winding package main body 1 is fixed in the lower motor housing 101.

[0039] See also Figure 1 - Figure 5 A sealing ring 8 is provided at the connection between the upper motor casing 102 and the lower motor casing 101. Through the setting of the sealing ring 8, there will be a gap at the connection between the motor casings when the upper motor casing 102 and the lower motor casing 101 are installed. When the motor is working, dust is likely to enter, resulting in potential danger when the motor is running. Therefore, under the action of the sealing ring 8, the dust can be effectively blocked, and the mounting frame 3 is made of elastic metal. When the mounting frame 3 moves into the lower motor casing 101 along with the stator winding body 1, the mounting frame 3 is elastically set, so that when the inner wall of the lower motor casing 101 squeezes the mounting frame 3, the mounting frame 3 generates a relative force, thereby better fixing the stator winding body 1 in the lower motor casing 101.

[0040] See also Figure 1 - Figure 5 The center of the first through hole 5 and the center of the second through hole 7 are on the same vertical line, and a plurality of support blocks 6 are symmetrically installed on the inner wall of the lower motor housing 101. By setting the number of support blocks 6, when the stator winding package body 1 moves into the lower motor housing 101, the support blocks 6 will support the stator winding package body 1, thereby making the stator winding package body 1 better fixed in the lower motor housing 101.

[0041] Embodiment 2

[0042] See also Figure 6 - Figure 7The difference between the second embodiment and the first embodiment is that, on the basis of retaining the first embodiment, the electric wire 9 is fixedly installed on the outer wall of the end of the stator winding package body 1, and a protective frame 10 for protecting the electric wire 9 is fixedly installed on the outer wall of the end of the stator winding package body 1. When installing the stator winding package body 1, the electric wire 9 may be adjusted due to the loose connection between the electric wire 9 and the stator winding package body 1, which may cause the electric wire 9 to fall off or break. By setting the protective frame 10, the electric wire 9 is wound on the protective frame 10, so as to effectively protect the connection between the electric wire 9 and the end of the stator winding package body 1, so that the electric wire 9 is not easily pulled off or falls off, and the protective frame 10 is located on one side of the electric wire 9. By setting the position of the protective frame 10, when the electric wire 9 is connected to the stator winding package body 1, the protective frame 10 will not affect the installation of the electric wire 9, so that it is more convenient for workers to install.

[0043] See also Figure 6 - Figure 7 There are multiple protection frames 10 installed at equal angles on the outer wall of the stator winding body 1. Since there may be more than one wire 9 at the end of the stator winding body 1, the protection frame 10 will change with the number of wires 9 to ensure that the protection frame 10 protects each wire 9.

[0044] See also Figure 6 - Figure 7 The protection frame 10 is made of elastic rubber. Since the wires 9 need to be bent when they are installed, the material of the protection frame 10 allows the protection frame 10 to protect the ends of the wires 9 without affecting the normal bending of the wires 9, making the protection frame 10 practical.

[0045] The working principle of the utility model is as follows: when in use, the stator winding package body 1 is placed in the lower motor housing 101. During the placement process, due to the outwardly inclined setting of the mounting frame 3, the stator winding package body 1 is installed in the lower motor housing 101, and the mounting frame 3 is squeezed by the inner wall of the lower motor housing 101. Since the mounting frame 3 is made of elastic metal material, when the stator winding package body 1 is installed in the lower motor housing 101, the mounting frame 3 simultaneously gives the same force to the lower motor housing 101. Through the mutual force of the mounting frame 3, the stator winding package body 1 is fixed in the lower motor housing 101. When the stator winding package body 1 is installed in the lower motor housing 101, the end of the mounting frame 3 The first through hole 5 at the top is aligned with the second through hole 7 at the end of the lower motor casing 101. As the stator winding body 1 moves into the lower motor casing 101, the mounting frame 3 is driven to move synchronously, so that the protrusion 4 at the end of the mounting frame 3 moves downward synchronously, so that when the protrusion 4 moves downward, the first through hole 5 is better aligned with the second through hole 7 under the guidance of the inclined surface of the outer wall. After the first through hole 5 is aligned with the second through hole 7, the upper motor casing 102 and the lower motor casing 101 are installed. While installing the motor casing, the mounting frame 3 is fixed together, so that the stator winding body 1 is fixed synchronously. When in use, the step of knocking the lower motor casing 101 is eliminated, thereby improving work efficiency.

[0046] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
