Description

Technical Field

[0001] This utility model relates to the field of motor installation technology, and in particular to a vibration damping installation structure for an AC induction geared motor. Background Technology

[0002] In modern life, AC motors are machines used to convert mechanical energy into alternating current electrical energy. Due to the massive development of AC power systems, AC motors have become the most commonly used type of motor. Compared to DC motors, AC motors are simpler in structure, easier to manufacture, more robust, and easier to produce high-speed, high-voltage, high-current, and high-capacity motors because they do not have a commutator. The power range of AC motors is very wide, from a few watts to hundreds of thousands or even millions of kilowatts. In the early 1980s, the largest steam turbine generators reached 1.5 million kilowatts.

[0003] The existing patent (publication number: CN214314897U) discloses an anti-vibration AC motor, which is simple and convenient to operate, highly practical, and improves the vibration reduction efficiency of the AC motor by setting a limit block and a first spring. The limit assembly further enhances the vibration reduction of the AC motor. The first mounting bracket and guide wheel improve the overall stability of the device. The second anti-slip pad facilitates better installation of the housing. The shock-absorbing airbag further improves the device's vibration resistance, significantly improving the work quality and efficiency compared to traditional devices. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] AC motors generate heat during use, requiring a cooling fan to continuously blow air to dissipate heat. However, the cooling fan produces considerable noise, affecting the working environment. Furthermore, it is not possible to limit and fix different motors during use; only a single model of motor can be fixed, which greatly limits its application. Utility Model Content

[0005] To address the aforementioned issues of excessive noise and the limitation to fixing only motor housings of fixed sizes, this invention provides a vibration damping mounting structure for an AC induction geared motor.

[0006] This utility model provides a vibration damping mounting structure for an AC induction geared motor, employing the following technical solution:

[0007] An AC induction geared motor vibration damping mounting structure includes an equipment housing, a top cover connected to the top of the equipment housing, a vibration damping airbag connected to the bottom of the top cover, a motor housing located below the vibration damping airbag, a filter screen connected to the left side of the equipment housing, a first sound-absorbing cotton disposed inside the filter screen, and a mounting block connected to the outside of the first sound-absorbing cotton.

[0008] A base plate is connected to the bottom of the motor housing. Insertion slots are provided on both sides of the base plate. An insertion block is connected inside the insertion slot. A movable block is connected to the center of the insertion block. A clamping block is connected above the movable block. A second sound-absorbing cotton is connected to the center of the clamping block.

[0009] The above technical solution facilitates the use of the first and second sound-absorbing cotton to reduce the noise generated by the cooling fan during operation, ensuring the equipment's usability. Furthermore, an insertion block and a movable block are provided above the base plate to limit the movement of motor housings of different sizes, improving adaptability and ensuring that the second sound-absorbing cotton adheres to one side of the motor to complete the noise reduction work.

[0010] Optionally, in the above-mentioned AC induction geared motor vibration damping installation structure, the equipment shell and the top cover are in a snap-fit ​​structure, the connection between the equipment shell and the filter screen is evenly and equidistantly distributed with threaded nails, and the top cover and the vibration damping airbag are installed as an integrated unit.

[0011] The above technical solution facilitates the use of the top cover and shock-absorbing airbags to limit the top and prevent it from moving.

[0012] Optionally, in the above-mentioned AC induction geared motor vibration damping mounting structure, the center of the motor housing coincides with the center of the base plate, and clamping blocks are symmetrically distributed on both sides of the motor housing. The clamping blocks and the insertion blocks are connected by heat fusion.

[0013] The above technical solution facilitates the use of clamping blocks and insertion blocks to limit and fix the motor housing, preventing it from moving.

[0014] Optionally, in the above-mentioned AC induction geared motor vibration damping mounting structure, the first sound-absorbing cotton has a conical structure, and mounting blocks are evenly and equidistantly distributed around the first sound-absorbing cotton. The mounting blocks are connected to the equipment shell by heat fusion connection.

[0015] The above technical solution facilitates the quick and easy installation of the first sound-absorbing cotton by cooperating with the mounting block.

[0016] Optionally, in the above-mentioned AC induction geared motor vibration damping installation structure, the connection between the movable block and the insertion block is a sliding connection, the insertion block passes through the insertion slot and engages with the base plate, and the base plate has insertion slots evenly distributed on both sides of the center.

[0017] The above technical solution facilitates the use of the insertion block to limit the movement of the moving block, and makes it easy to quickly adjust the position of the moving block.

[0018] Optionally, in the above-mentioned AC induction geared motor vibration damping installation structure, the clamping block and the second sound-absorbing cotton are connected by a sliding connection, and the clamping block on the right side has a slot in the center, and the clamping block on the right side does not directly contact the motor rod.

[0019] The above technical solution facilitates the movement of the second sound-absorbing cotton by the second clamping block, ensuring that the second sound-absorbing cotton adheres to the surface of the motor housing.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] The first sound-absorbing cotton is installed on the left side of the equipment casing to initially filter the noise emitted by the motor's cooling fan. At the same time, the clamping block will also move the second sound-absorbing cotton, so that the second sound-absorbing cotton is close to the side of the motor, ensuring secondary absorption of the noise emitted by the cooling fan, thereby reducing noise and improving the working environment.

[0022] By having movable clamping blocks and movable blocks on both sides of the motor housing cooperate with each other, the clamping blocks can move left and right, thereby limiting and fixing motor housings of different sizes. This allows the equipment housing to be adapted to any AC motor, improving the applicability of the equipment. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1-4This utility model provides an embodiment of an AC induction geared motor vibration damping mounting structure, including a device housing 1, a top cover 2 connected to the top of the device housing 1, which cooperates with a vibration damping airbag 3 to fix the top of the motor housing 4, a vibration damping airbag 3 connected to the bottom of the top cover 2, and a motor housing 4 disposed below the vibration damping airbag 3, a filter screen 6 connected to the left side of the device housing 1, the filter screen 6 is used to prevent debris from entering the interior of the device housing 1 and to ensure ventilation, a first sound-absorbing cotton 5 is disposed inside the filter screen 6, and a mounting block 7 is connected to the outside of the first sound-absorbing cotton 5, the first sound-absorbing cotton 5 is fixed by the mounting block 7 to initially reduce noise.

[0030] A base plate 8 is connected to the bottom of the motor housing 4. Insertion slots 11 are provided on both sides of the base plate 8. The insertion slots 11 cooperate with the insertion block 10 to limit and fix the movable block 9. The insertion block 10 is connected inside the insertion slot 11. The movable block 9 is connected to the center of the insertion block 10. A clamping block 12 is connected above the movable block 9. The second sound-absorbing cotton 13 is connected to the center of the clamping block 12. The clamping block 12 is used to fix the motor housing 4 and at the same time change the position of the second sound-absorbing cotton 13 to ensure the noise reduction effect of the second sound-absorbing cotton 13.

[0031] Working principle: When in use, first, open the top cover 2, place the motor housing 4 that needs to be damped above the bottom plate 8, then move the clamping block 12 so that it fits against both sides of the motor housing 4, then insert the insertion block 10 into the insertion slot 11 to complete the limiting and fixing work of the movable block 9. At this time, close the top cover 2 so that the shock-absorbing airbag 3 fits against the top of the motor housing 4 to complete the fixing work. During use, the shock-absorbing damping under the bottom plate 8 provides shock absorption and buffering.

[0032] As mentioned above, during use, the clamping block 12 moves the second sound-absorbing cotton 13 to the left side of the motor housing 4. When the heat is too high, the cooling fan works, and the airflow flows through the second sound-absorbing cotton 13 and its central hole to dissipate heat. At the same time, the second sound-absorbing cotton 13 performs initial noise reduction, and performs secondary noise reduction when the gas flows through the first sound-absorbing cotton 5.

[0033] It should be further explained that the outer casing 1 and the top cover 2 are interlocking, and the connection between the outer casing 1 and the filter screen 6 is evenly and equidistantly distributed with threaded nails. The top cover 2 and the shock-absorbing airbag 3 are installed as a whole. The top cover 2 and the shock-absorbing airbag 3 work together to limit the top and prevent it from moving.

[0034] It should be noted that the center of the motor housing 4 coincides with the center of the base plate 8. Clamping blocks 12 are symmetrically distributed on both sides of the motor housing 4. The clamping blocks 12 and the insertion blocks 10 are connected by heat fusion. The clamping blocks 12 and the insertion blocks 10 cooperate to limit and fix the motor housing 4 to prevent it from moving.

[0035] It should be further explained that the first sound-absorbing cotton 5 has a conical structure, and mounting blocks 7 are evenly distributed around the first sound-absorbing cotton 5. The mounting blocks 7 are connected to the equipment shell 1 by heat fusion. The first sound-absorbing cotton 5 is quickly fixed and installed by cooperating with the mounting blocks 7.

[0036] It should be noted that the connection between the movable block 9 and the insertion block 10 is a sliding connection. The insertion block 10 passes through the insertion groove 11 and engages with the base plate 8. The insertion grooves 11 are evenly distributed on both sides of the center of the base plate 8. The insertion block 10 is used to limit the position of the movable block 9, which facilitates the quick adjustment of the position of the movable block 9.

[0037] It should be noted that the clamping block 12 and the second sound-absorbing cotton 13 are connected by a sliding connection, and the clamping block 12 on the right side has a slot in the center. The clamping block 12 on the right side does not directly contact the motor rod. The second sound-absorbing cotton 13 is moved by the second clamping block 12 to ensure that the second sound-absorbing cotton 13 is attached to the surface of the motor housing 4.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
