Description

Technical Field

[0001] The utility model relates to a starting generator motor, in particular to a water-cooled starting generator motor. Background Art

[0002] The starter generator motor is a device used to start the motor and generate electricity after the motor is started. During the operation of the starter generator motor, the rotor assembly will generate heat during the rotation relative to the stator assembly, thereby affecting the overall working efficiency of the motor;

[0003] The conventional solution is to achieve heat dissipation of the motor through a water-cooling shell. However, due to the bent water cooling channel of the water-cooling shell, the processing of the water-cooling shell is difficult, and short circuits are prone to occur between the water-cooling shells, resulting in only partial cooling of the motor.

[0004] In summary, how to realize the setting of cooling channels in the starting generator motor to facilitate processing and forming has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to realize the setting of the cooling channel in the starter generator motor to facilitate processing and forming;

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model discloses a water-cooled starting generator motor, comprising: a casing, in which a stator assembly is arranged; a rotor assembly, which is rotatably arranged in the stator assembly; a water-cooling assembly, which is arranged at a gap between the casing and the stator assembly; the water-cooling assembly comprises an extended cooling groove extending to the bottom of the stator assembly; a cover plate, which is fixedly connected to the casing and limits the water-cooling assembly in the casing; a water inlet pipe and a water outlet pipe, the top surface of the water-cooling assembly is provided with the water inlet pipe and the water outlet pipe; when the motor needs to be cooled, cooling water enters the water-cooling assembly through the water inlet pipe, and after heat exchange is achieved, the cooling water is discharged from the water outlet pipe;

[0008] In this solution, cooling water enters the water-cooling assembly, and heat exchange is achieved for the stator assembly and the rotor assembly through the water-cooling assembly. After the heat exchange is completed, the cooling water is discharged from the water-cooling assembly to cool the starting generator motor. By setting an extended cooling groove, the bottom of the stator assembly can be cooled, thereby improving the cooling efficiency of the starting motor.

[0009] In addition, the cover plate confines the water cooling assembly within the housing, restricting the axial movement of the water cooling assembly relative to the housing, and the inner wall of the water cooling assembly provides a rotation position for the rotation of the main shaft in the rotor assembly;

[0010] Cooling water is one of the cooling media, and cooling water can also be replaced by insulating oil for cooling.

[0011] In order to illustrate the specific structure of the water cooling component, the utility model adopts a water cooling component, including: a body; a plurality of cooling channels, a plurality of cooling channels are opened along the axial direction of the body; the plurality of cooling channels are clockwise or counterclockwise denoted as 1, 2, 3, ...a, ....n, where a and n are both positive integers; wherein, if a first reversing cavity is formed between the top of the ath cooling channel and the top of the a+1th cooling channel and the cover plate, a second reversing cavity is formed between the bottom of the ath cooling channel and the bottom of the a-1th cooling channel and the support plate of the housing;

[0012] In this solution, cooling water enters from the top of the first cooling channel, and enters the second reversing cavity, the second cooling channel, the first reversing cavity, the third cooling channel, the second reversing cavity, the fourth cooling channel, the first reversing cavity..., and so on, and finally is discharged from the water outlet pipe; the cooling water flows unidirectionally in the cooling channel in a serpentine shape; with this solution, only the axial cooling channel and the first reversing cavity and the second reversing cavity on the end face of the body need to be opened, and the cooling channel is opened in a straight line, which reduces the processing difficulty compared with the traditional water cooling components;

[0013] A water inlet pipe and a water outlet pipe are arranged on the same side of the water cooling component in order to save space, but this places a number requirement on the cooling channels in the water cooling component, and the number of cooling channels must be an even multiple.

[0014] In order to facilitate the installation of the stator assembly, the utility model adopts the body to be divided into an upper body and a lower body; the cooling channels of the upper body and the lower body are coaxially arranged; the inner walls of the upper body and the lower body form an installation groove for installing the stator assembly;

[0015] In this solution, the main body is a split structure. The lower body is first installed in the casing, the rotor assembly is installed in the casing, and then the stator assembly, the rotor assembly, and the cover plate are installed, thus realizing the installation of the stator assembly.

[0016] In order to specifically explain the specific installation position of the extended cooling groove, the utility model adopts the bottom of the second reversing groove to extend the extended cooling groove inward along the radial direction of the body;

[0017] The bottom of the stator assembly can be cooled by providing an extended cooling groove.

[0018] In order to prevent cooling water from entering the rotor assembly, the utility model adopts a sealing ring disposed between the top of the water cooling assembly and the cover plate; the sealing ring limits the cooling water from entering the stator assembly;

[0019] The sealing ring is provided to limit the cooling water from entering the stator assembly.

[0020] The beneficial effects of the utility model are as follows: the utility model is a water-cooled starting generator motor, cooling water enters into the water-cooling component, and heat exchange of the stator component and the rotor component is realized through the water-cooling component. The cooling water after the heat exchange is completed is discharged from the water-cooling component to realize cooling of the starting generator motor. By setting an extended cooling groove, the bottom of the stator component can be cooled, thereby improving the cooling efficiency. In addition, the cooling channel is opened in a straight line along the axial direction of the main body, and the processing difficulty is reduced compared with the traditional water-cooling component.

DETAILED DESCRIPTION

[0027] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0028] like Figure 1-2As shown, the utility model is a water-cooled starting generator motor, comprising: a casing 1, in which a stator assembly 2 is arranged; a rotor assembly 3, which is rotatably arranged in the stator assembly 2; a water-cooling assembly 4, which is arranged at the gap between the casing 1 and the stator assembly 2; the water-cooling assembly 4 includes an extended cooling groove 45 extending to the bottom of the stator assembly 2; a cover plate 5, which is fixedly connected to the casing 1 and limits the water-cooling assembly 4 in the casing 1; a water inlet pipe 6 and a water outlet pipe 7, both of which are arranged on the same side of the water-cooling assembly 4 and are located on the top surface of the water-cooling assembly 4; when the motor needs to be cooled, cooling water enters the water-cooling assembly 4 through the water inlet pipe 6, and after heat exchange is achieved, the cooling water is discharged from the water outlet pipe 7;

[0029] In this solution, cooling water enters the water-cooling assembly, and heat exchange is achieved between the stator assembly and the rotor assembly through the water-cooling assembly. After the heat exchange is completed, the cooling water is discharged from the water-cooling assembly to cool the starting generator motor. By setting an extended cooling groove, the bottom of the stator assembly can be cooled, thereby improving the cooling efficiency.

[0030] In addition, the cover plate confines the water cooling assembly within the housing, restricting the axial movement of the water cooling assembly relative to the housing, and the inner wall of the water cooling assembly provides a rotation position for the rotation of the main shaft in the rotor assembly;

[0031] like Figure 2-4 As shown, in order to illustrate the specific structure of the water cooling component, the utility model adopts a water cooling component 4, including: a body 41; a plurality of cooling channels 42, a plurality of cooling channels 42 are opened along the axial direction of the body 41; the plurality of cooling channels 42 are clockwise or counterclockwise denoted as 1, 2, 3, ...a, ....n, wherein a and n are both positive integers; wherein, if a first reversing cavity 43 is formed between the top of the ath cooling channel 42 and the top of the a+1th cooling channel 42 and the cover plate 5, a second reversing cavity 44 is formed between the bottom of the ath cooling channel 42 and the bottom of the a-1th cooling channel 42 and the support plate 11 of the housing 1;

[0032] In this solution, cooling water enters from the top of the first cooling channel, and enters the second reversing cavity, the second cooling channel, the first reversing cavity, the third cooling channel, the second reversing cavity, the fourth cooling channel, the first reversing cavity, and so on in sequence, and finally is discharged from the water outlet pipe; the cooling water flows unidirectionally in the cooling channel in a serpentine shape; with this solution, only the axial cooling channel and the first reversing cavity and the second reversing cavity on the end face of the body need to be opened, and the cooling channel is opened in a straight line, which reduces the processing difficulty compared with the traditional water cooling components;

[0033] The water inlet pipe and the water outlet pipe are arranged on the top surface of the water-cooling component in order to save the installation space of the water-cooling component. Water enters the cold water component on the same side and exits the water on the same side after heat exchange. In other words, the water inlet pipe and the water outlet pipe are arranged on the same side of the water-cooling component in order to save space, but this provides a quantity requirement for the cooling channels in the water-cooling component, and the number of cooling channels must be an even multiple.

[0035] In this solution, the main body is a split structure. The lower body is first installed in the casing, the rotor assembly is installed in the casing, and then the stator assembly, the rotor assembly, and the cover plate are installed, thus realizing the installation of the stator assembly.

[0036] like Figure 4 As shown, in order to specifically illustrate the specific installation position of the extended cooling groove, the utility model adopts the bottom of the second reversing groove 44 extending inward along the body diameter 41 to extend the extended cooling groove 45

[0037] The bottom of the stator assembly can be cooled by providing an extended cooling groove.

[0038] like Figure 3 As shown, in order to prevent cooling water from entering the rotor assembly, the utility model uses a sealing ring 8 disposed between the top of the water cooling assembly 4 and the cover plate 5; the sealing ring 8 limits the cooling water from entering the stator assembly 2;

[0039] The sealing ring is provided to limit the cooling water from entering the stator assembly.
