DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] like Figures 1-7 As shown, a water cooler for an electric motor includes a connecting ring 1, a cooling cover 2, and a connecting assembly 3. The connecting ring 1 consists of two connecting half-rings 10, which are fixedly connected to each other. During installation, the two connecting half-rings 10 are fixedly connected by the two connecting half-rings, clamping the motor housing. The cooling cover 2 is provided with a base for installation, i.e., corresponding connecting ears 11 are provided on the connecting half-rings 10.

[0026] The cooling cover 2 includes a first cooling cover 20 and a second cooling cover 21; both the first cooling cover 20 and the second cooling cover 21 are hollow structures. Both the first cooling cover 20 and the second cooling cover 21 are provided with an inlet pipe 22 and an outlet pipe 23. Cooling water enters the hollow structure through the inlet pipe 22 and then flows out through the outlet pipe 23.

[0027] The first cooling cover 20 and the second cooling cover 21 are combined to form a disc-shaped structure with a through hole in the middle. That is, the cooling cover 2 adopts a split-combination structure, which ensures that the cooling cover 2 can be installed without stopping the motor and disassembling it.

[0028] Two wedge-shaped blocks 24 are fixed on the first cooling cover 20 and the second cooling cover 21 respectively; specifically, two wedge-shaped blocks 24 are fixed on the first cooling cover 20 and the second cooling cover 21 respectively, located at the upper and lower ends.

[0029] The connecting assembly 3 includes a connecting cover 30 and a connecting bolt 31. The connecting cover 30 has an inclined surface 300 that engages with the wedge block 24. One end of the connecting bolt 31 passes through the connecting cover 30 and the connecting lug 11 and connects to the nut. During the tightening of the connecting bolt 31, the connecting cover 30 moves towards the connecting lug 11, and the inclined surface 300 engages with the wedge block 24, shortening the distance between the opposing wedge blocks 24 fixed on the first cooling cover 20 and the second cooling cover 21 until they are in contact. At the same time, the connecting cover 30 also drives the first cooling cover 20 and the second cooling cover 21 to move towards the connecting lug 11. That is, by simply tightening the connecting bolt 31, the combination of the first cooling cover 20 and the second cooling cover 21, as well as the contact between the first cooling cover 20 and the second cooling cover 21 and the motor end cover, can be achieved.

[0030] The specific installation process is as follows: First, fix the two connecting half rings 10 to the outer casing of the motor; then, assemble the first connecting cover 30 and the second connecting cover 30 at the end cover of the motor; finally, tighten the connecting bolts 31.

[0031] The specific cooling process is as follows: cooling water enters the cavity structure through the water inlet pipe 22, and then flows out through the water outlet pipe 23, thereby taking away the heat at the motor end cover (and the bearing), and achieving the purpose of cooling.

[0032] Further, an arc-shaped through hole is arranged on the connecting lug 11, that is, the connecting bolt 31 can have a certain range of movement during installation, thereby facilitating installation.

[0033] Further, a semicircular limiting hole 240 is arranged on the wedge-shaped block 24; after the connecting bolt 31 is screwed, the semicircular limiting holes 240 on the two opposite wedge-shaped blocks 24 form a complete circular through hole. The structure arrangement can ensure that the connecting bolt 31 can pass through the wedge-shaped block 24 during installation.

[0034] Further, the above structure arrangement is mainly for cooling the end cover where the bearing is located, so as to avoid high temperature at the bearing; and the above installation method does not need to disassemble the already installed motor, and can directly be added. However, the temperature of the rotor of the motor will also rise during actual operation, and thus the temperature of the output shaft will also rise. Therefore, the water cooler further comprises a shaft sleeve 4.

[0035] The shaft sleeve 4 is fixedly connected with the cooling cover 2, a protrusion 40 is arranged on the shaft sleeve 4, and a corresponding recess 25 is arranged on the cooling cover 2 (that is, a corresponding half recess 25 is arranged on the first cooling cover 20 and the second cooling cover 21, and the complete recess 25 is formed after combination); the shaft sleeve 4 is rotatably connected with the output shaft of the motor. Therefore, after the shaft sleeve 4 is installed, the heat at the output shaft is transmitted to the cooling cover 2 through the shaft sleeve 4.

[0036] When the shaft sleeve 4 is installed, the already installed motor needs to be disassembled, so that the shaft sleeve 4 can be installed on the output shaft of the motor. Therefore, the case is suitable for use when the output shaft needs to be cooled.

[0037] Further, the two connecting half rings 10 are fixedly connected through the fixing bolt 12.

[0038] Further, a plurality of staggered partition plates 26 are arranged in the first cooling cover 20 and the second cooling cover 21, so that water flow channels are formed in the first cooling cover 20 and the second cooling cover 21. The water inlet pipe 22 and the water outlet pipe 23 of the first cooling cover 20 and the second cooling cover 21 can be connected through a three-way pipe; that is, the cooling water flows into the water inlet pipe 22 of the first cooling cover 20 and the second cooling cover 21 through the three-way pipe, and the cooling water (after heat absorption) flowing out of the water outlet pipe 23 of the first cooling cover 20 and the second cooling cover 21 is discharged through the three-way pipe.

[0039] The above only describes the preferred embodiments of the utility model in detail, but the utility model is not limited to the above embodiments.
