Description

Technical Field

[0001] This invention belongs to the field of motor technology, specifically relating to a washer structure and a motor, which are energy-saving starter motors and energy-saving electric motors. Background Technology

[0002] During motor installation, traditional I-beam type vibration damping washers often suffer from installation difficulties, inaccurate positioning, and poor damping performance due to their simple structure and limited installation space. Especially between the motor bracket and the mounting surface, if the washer cannot achieve good contact and cushioning, it can easily lead to vibration transmission, structural fatigue, and even equipment damage. Existing technologies employ I-beam type washer structures for vibration damping design; however, because the edges of the I-beam washer are thin and lack flexibility, they are prone to twisting, tearing, or localized crushing during insertion due to localized stress concentration. Therefore, there is an urgent need for a washer assembly with a reasonable structure, convenient installation, and excellent vibration damping performance to meet the needs of different motor installation scenarios.

[0003] Due to the technical problems of easy damage and difficult installation of I-shaped washers in the existing technology, this invention studies and designs a washer structure and motor, which belong to the category of energy-saving starter motors and energy-saving electric motors. Summary of the Invention

[0004] Therefore, the present invention provides a washer structure and a motor, which belong to the category of energy-saving starter motors and energy-saving electric motors, and can solve the technical problem of difficult installation of I-shaped washers in the prior art.

[0005] To solve the above problems, the present invention provides a washer structure, comprising: a first part and a second part, wherein the first part is provided with a first through hole and the second part is provided with a second through hole, and a portion of the second part can pass through a motor mounting hole and be inserted into the first part. When the second part is inserted into the first part, the motor mounting hole, the first through hole and the second through hole are arranged coaxially.

[0006] In some embodiments, the first part includes a first body, one end of which is provided with a first protrusion and a second protrusion, and one end of which is provided with a first through hole. The first protrusion and the second protrusion are annular, the second protrusion is located inside the first protrusion, the first protrusion, the second protrusion and the first through hole are arranged coaxially, and a portion of the second part can be inserted between the first protrusion and the second protrusion.

[0007] In some embodiments, one end of the first body is provided with a plurality of third protrusions, which are located radially outward of the first protrusions along the radial direction of the first body.

[0008] In some embodiments, the peripheral wall of the first protrusion is provided with a plurality of fifth protrusions, and the outer peripheral wall of the second protrusion is provided with a plurality of fourth protrusions.

[0009] In some embodiments, a plurality of the fifth protrusions are arranged circumferentially spaced along the first protrusion, and a plurality of the fourth protrusions are arranged circumferentially spaced along the second protrusion.

[0010] In some embodiments, the fifth protrusion extends axially along the first protrusion to form a wavy structure on the inner peripheral wall of the first protrusion, and the fourth protrusion extends axially along the second protrusion to form a wavy structure on the outer peripheral wall of the second protrusion.

[0011] In some embodiments, the inner and outer peripheral walls of the portion into which the second part can be inserted are both wavy structures, the wavy structure of the second part is asymmetrical with the fifth protrusion, and the wavy structure of the second part is asymmetrical with the fourth protrusion.

[0012] In some embodiments, the number of the fifth protrusion and the number of the fourth protrusion are integer multiples of the number of waveforms in the wave-shaped structure of the second part.

[0013] In some embodiments, the second part includes a second body, one end of which is provided with a second through hole, and another end of which is provided with a sixth protrusion. The sixth protrusion is annular and coaxially arranged with the second through hole, and the sixth protrusion can be inserted into the first part.

[0014] In some embodiments, the inner peripheral wall of the sixth protrusion is provided with a plurality of eighth protrusions, and the outer peripheral wall of the sixth protrusion is provided with a plurality of seventh protrusions.

[0015] In some embodiments, a plurality of the seventh protrusions are arranged circumferentially spaced along the sixth protrusion, and a plurality of the eighth protrusions are arranged circumferentially spaced along the sixth protrusion.

The mounting plate is provided with a boss, the first part matches the boss, the feet are provided with motor mounting holes, the second part passes through the motor mounting holes and is inserted into the first part, and a fastener passes through the first through hole and the second through hole and is fixedly connected to the boss.

[0018] The washer structure and motor provided by this invention have the following beneficial effects:

[0019] When installing the washer structure, simply insert the second part through the motor's mounting hole into the first part, thus providing protection on both sides of the motor's mounting portion. The motor is then fixed to the mounting surface using screws, creating a soft contact between the motor bracket and the mounting surface for effective vibration damping. The insertion of the first and second parts forms an I-beam structure, avoiding problems such as twisting, tearing, or localized crushing caused by localized stress concentration during the insertion process of existing I-beam structures. This soft contact between the motor bracket and the mounting surface, along with the first and second parts, makes washer installation more convenient, effectively aligning the mounting holes. Each part can be replaced independently to adapt to the installation needs of different motors, providing an energy-saving starter motor and energy-saving electric motor. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0035] See also Figure 1-8 As shown in the embodiment of the present invention, a washer structure is provided, comprising: a first part and a second part. The first part is provided with a first through hole 4, and the second part is provided with a second through hole 10. A portion of the second part can pass through a motor mounting hole and be inserted into the first part. When the second part is inserted into the first part, the motor mounting hole, the first through hole 4, and the second through hole 10 are coaxially arranged. In this technical solution, when the washer structure is installed, only a portion of the second part needs to pass through the motor mounting hole and be inserted into the first part, thereby forming protection on both sides of the motor mounting portion. The motor is fixed to the mounting surface of the whole machine by screw connectors, so that a soft contact is formed between the motor bracket and the mounting surface, thereby achieving a good vibration damping effect. The first and second parts, when inserted together, form an I-shaped structure, avoiding problems such as twisting, tearing, or local crushing caused by local stress concentration during the insertion of existing I-shaped structures. This allows for soft contact between the motor bracket and the mounting surface. Furthermore, the first and second parts make it easier to install the gasket and effectively align the mounting holes. Each part can be replaced independently to adapt to the installation requirements of different motors, providing an energy-saving starter motor and an energy-saving electric motor.

[0036] In some embodiments, the first part includes a first body 1, one end of which is provided with a first protrusion 2 and a second protrusion 3, and one end of which is provided with a first through hole 4. The first protrusion 2 and the second protrusion 3 are annular, the second protrusion 3 is located inside the first protrusion 2, the first protrusion 2, the second protrusion 3 and the first through hole 4 are arranged coaxially, and a portion of the second part can be inserted between the first protrusion 2 and the second protrusion 3.

[0037] In this technical solution, the first body 1, the first protrusion 2, and the second protrusion 3 are made of relatively soft and elastic materials, preferably with a Shore hardness between 20 and 50, such as silicone or nitrile rubber. The first body 1 has a T-shaped structure, and the first protrusion 2 and the second protrusion 3 can clamp the second part, facilitating the installation of the first and second parts and making the fit between the first and second parts more stable.

[0038] In some embodiments, the diameter of the first through hole 4 is not greater than the inner diameter of the second protrusion 3. Preferably, the diameter of the first through hole 4 is the same as the inner diameter of the second protrusion 3. When the screw passes through the first through hole 4, the inner peripheral wall of the second protrusion 3 can fix the screw and dampen vibration, further improving the vibration damping effect.

[0039] In some embodiments, the outer diameter of the first protrusion 2 is not greater than the diameter of the mounting hole, that is, the first protrusion 2 can pass through the mounting hole, making the first part and the second part more securely installed. The first protrusion 2, the second part and the second protrusion 3 form a triple vibration reduction effect between the inner wall of the mounting hole and the fixing screw, thereby improving the vibration reduction effect of the motor.

[0040] In some embodiments, the first protrusion 2 and the second protrusion 3 have the same height. In this technical solution, when the first protrusion 2 and the second protrusion 3 have the same height, the first protrusion 2 and the second protrusion 3 can simultaneously abut against the end face of the second part, providing support for the second part and making the force on the second part more even.

[0041] In some embodiments, the first protrusion 2 and the second protrusion 3 are arranged at intervals along the radial direction of the first protrusion 2, and the second protrusion 3 is located radially inside the first protrusion 2. This allows the second portion to be inserted between the first protrusion 2 and the second protrusion 3.

[0042] In some embodiments, the outer diameter of the first protrusion 2 is smaller than the outer diameter of the first body 1. This allows the end face of the first body 1 to support the mounting surface of the mounting leg when the first protrusion 2 passes through the mounting hole, thereby increasing the vibration damping area.

[0043] In some embodiments, the first body 1 is circular, with a first through hole 4 in the center, and a first protrusion 2 and a second protrusion 3 located on one end face of the first body 1. This allows the fixing screw to be located inside the second protrusion 3, facilitating the installation of the washer structure.

[0044] In some embodiments, one end of the first body 1 is provided with a plurality of third protrusions 5, which are located radially outward of the first protrusions 2 along the radial direction of the first body 1.

[0045] In this technical solution, the third protrusion 5 is a hemispherical protrusion, and one end of the first body 1 is provided with multiple third protrusions 5, which enhances the friction and shock absorption capacity between the first body 1 and the mounting surface.

[0046] In some embodiments, the peripheral wall of the first protrusion 2 is provided with a plurality of fifth protrusions 7, and the outer peripheral wall of the second protrusion 3 is provided with a plurality of fourth protrusions 6.

[0047] In this technical solution, by providing multiple fifth protrusions 7 on the peripheral wall of the first protrusion 2 and multiple fourth protrusions 6 on the outer peripheral wall of the second protrusion 3, the first protrusion 2 and the second protrusion 3 have good deformation adaptability and buffering performance, and further enable the first protrusion 2 and the second protrusion 3 to provide multi-point contact with the inserted second part, preventing rotation and reducing stress concentration.

[0048] In some embodiments, a plurality of the fifth protrusions 7 are arranged circumferentially spaced along the first protrusion 2, and a plurality of the fourth protrusions 6 are arranged circumferentially spaced along the second protrusion 3.

[0049] In this technical solution, multiple fifth protrusions 7 are arranged at intervals along the circumference of the first protrusion 2, and multiple fourth protrusions 6 are arranged at intervals along the circumference of the second protrusion 3, so that the inner and outer peripheral walls of the second part are uniformly contacted in the circumferential direction, thereby improving the deformation adaptability and buffering performance of the first protrusion 2 and the second protrusion 3 and improving the vibration reduction effect.

[0050] In some embodiments, the fifth protrusion 7 extends along the axial direction of the first protrusion 2 to form a wave-like structure on the inner peripheral wall of the first protrusion 2, and the fourth protrusion 6 extends along the axial direction of the second protrusion 3 to form a wave-like structure on the outer peripheral wall of the second protrusion 3.

[0051] In this technical solution, the outer peripheral wall of the second protrusion 3 forms a wave-like structure and the inner peripheral wall of the first protrusion 2 forms a wave-like structure, so that the second protrusion 3 and the first protrusion 2 have good deformation adaptability and buffering properties.

[0052] In some embodiments, the inner and outer peripheral walls of the portion into which the second part can be inserted are both wavy structures. The wavy structure of the second part is asymmetrical with the fifth protrusion 7 and the wavy structure of the second part is asymmetrical with the fourth protrusion 6.

[0053] In this technical solution, the wave-shaped structure of the second part is asymmetrical with the fifth protrusion 7, and the wave-shaped structure of the second part is asymmetrical with the fourth protrusion 6, which avoids the resonance risk that is easy to be generated by the traditional "symmetrical fit", and makes the stress form a gradient distribution on the contact surface.

[0054] In some embodiments, the number of the fifth protrusion 7 and the number of the fourth protrusion 6 are integer multiples of the number of waveforms in the wave-shaped structure of the second part.

[0055] In this technical solution, the number of the fifth protrusion 7 and the number of the fourth protrusion 6 are integer multiples of the number of waveforms in the wave-shaped structure of the second part, so as to ensure the stability and consistency of the fit.

[0056] In some embodiments, the second part includes a second body 8, one end of which is provided with a second through hole 10, and another end of which is provided with a sixth protrusion 9. The sixth protrusion 9 is annular and coaxially arranged with the second through hole 10. The sixth protrusion 9 can be inserted into the first part.

[0057] In this technical solution, the second body 8 and the sixth protrusion 9 are made of a material with high hardness, meaning a Shore hardness between 60 and 90, such as polyurethane or modified epoxy resin. The second body 8 and the sixth protrusion 9 create a T-shaped structure for the second part, facilitating its insertion into the first part and achieving a proper fit between them.

[0058] In some embodiments, the second body 8 is circular with a second through hole 10 in the center. This allows the fixing screw to be located inside the sixth protrusion 9, facilitating the installation of the washer structure.

[0059] In some embodiments, the diameter of the second through hole 10 is smaller than the inner diameter of the sixth protrusion 9. Along the radial direction of the first body 1, the second protrusion 3 has a thickness. There is a difference between the inner diameter of the sixth protrusion 9 and the diameter of the second through hole 10, which is equal to the thickness of the second protrusion 3. This allows the second protrusion 3 to abut against the end face of the second body 8 after the second part is inserted into the first part, thereby increasing the support area of ​​the first part and the second part and improving the structural stability.

[0060] Preferably, the inner diameter of the second protrusion 3 is equal to the diameter of the second through hole 10. This ensures that the inner peripheral wall of the second protrusion 3 can dampen the fixing screw and increase the contact area between the washer structure and the fixing screw.

[0061] In some embodiments, the inner peripheral wall of the sixth protrusion 9 is provided with a plurality of eighth protrusions 12, and the outer peripheral wall of the sixth protrusion 9 is provided with a plurality of seventh protrusions 11.

[0062] In this technical solution, by providing multiple eighth protrusions 12 on the inner peripheral wall of the sixth protrusion 9 and multiple seventh protrusions 11 on the outer peripheral wall of the sixth protrusion 9, the sixth protrusion 9 has good deformation adaptability and buffering performance when inserted into the first part, providing multi-point contact to the first part, preventing rotation and reducing stress concentration.

[0063] In some embodiments, a plurality of the seventh protrusions 11 are arranged circumferentially spaced along the sixth protrusion 9, and a plurality of the eighth protrusions 12 are arranged circumferentially spaced along the sixth protrusion 9.

[0064] In this technical solution, multiple seventh protrusions 11 are arranged at intervals along the circumference of the sixth protrusion 9, and multiple eighth protrusions 12 are arranged at intervals along the circumference of the sixth protrusion 9, so that the contact surface of the first part is uniformly contacted in the circumferential direction, thereby improving the deformation adaptability and buffering performance of the sixth protrusion 9 and improving the vibration reduction effect.

[0065] In some embodiments, the eighth protrusion 12 extends axially along the sixth protrusion 9 to form a wavy structure on the inner peripheral wall of the sixth protrusion 9, and the seventh protrusion 11 extends axially along the second protrusion 3 to form a wavy structure on the outer peripheral wall of the sixth protrusion 9. This technical solution results in a wavy contact surface at the insertion portion of the first part and the second part, increasing the contact area between the first part and the second part, increasing the friction area between the first part and the second part, preventing the first part from rotating relative to the second part, and effectively dispersing stress.

[0066] The gasket structure of the present invention includes a first part and a second part. The first part is a large T-shaped soft rubber gasket, and the second part is a small T-shaped hard rubber gasket. The large T-shaped soft rubber gasket is made of a relatively soft and elastic material. (See also...) Figure 3 and Figure 4 As shown, the diameter of the first end face of the large T-shaped soft rubber washer is not less than the diameter of the boss 14. Its thickness is the same as the thickness of the motor mounting foot 17. The second end face of the large T-shaped soft rubber washer has an appropriate number of 1-6 small hemispherical protrusions unevenly distributed. The first protrusion 2 mates with the mounting hole of the motor mounting foot 17, and the outer diameter of the first protrusion 2 is consistent with the diameter of the mounting hole. The thickness of the first protrusion 2 is the same as the thickness of the motor mounting foot 17, so that the upper and lower end faces of the motor mounting foot 17 are in direct contact with the second end face of the large T-shaped soft rubber washer and the second end face of the small T-shaped hard rubber washer, thereby transmitting vibration and energy from the motor mounting foot 17. The outer peripheral wall of the second protrusion 3 and the inner peripheral wall of the first protrusion 2 have respectively mated with the inner and outer peripheral walls of the sixth protrusion 9 of the small T-shaped hard rubber washer during assembly. The third protrusion 5 is a non-uniformly distributed small hemispherical protrusion, with a diameter no greater than 1 / 28 of the outer diameter of the first main body 1. It is used to increase friction with the mounting surface and improve shock absorption stability. The vertical portion of the large T-shaped soft rubber washer is designed as a double-layer cylindrical structure. Both the outer peripheral wall of the second protrusion 3 and the inner peripheral wall of the first protrusion 2 are provided with wavy annular grooves to enhance their compression deformation capacity and cushioning performance. There is a gap between the second protrusion 3 and the first protrusion 2. During assembly, the second end face of the portion in the gap between the second protrusion 3 and the first protrusion 2 abuts against the sixth protrusion 9. The first end face of the large T-shaped soft rubber washer mates with the boss 14. The inner peripheral wall of the second protrusion 3 mates with the middle portion of the internal hexagon screw.

[0067] See also Figure 5 and Figure 6As shown, the small T-shaped hard rubber washer is made of a material with high hardness. The diameter of the second body 8 is slightly smaller than that of the first body 1, and its thickness is slightly smaller than that of the first body 1. During assembly, the first end face of the small T-shaped hard rubber washer mates with the upper end face of the motor mounting bracket 17. The vertical portion of the small T-shaped hard rubber washer has a single-layer corrugated cylindrical structure, and both the inner and outer walls of the sixth protrusion 9 have corrugated structures, forming an asymmetrical concave-convex fit with the corrugated structure of the large T-shaped soft rubber washer. The second end face of the second body 8 is in direct contact with the head of the internal hexagon screw.

[0068] During mating, the single-layer cylindrical portion of the small T-shaped hard rubber washer is inserted into the double-layer cylindrical portion of the large T-shaped soft rubber washer. The wavy structure of the large and small T-shaped washers forms an asymmetrical concave-convex mating structure. (See attached diagram for details.) Figure 2 As shown, this mating method allows for multi-point contact between the two components during assembly, preventing rotation and effectively distributing stress. Furthermore, the number of wave patterns on the soft washer is an integer multiple of that on the hard washer to ensure stability and consistency in the fit.

[0069] Compared with traditional I-beam type shock-absorbing washers, the washer structure of this invention has advantages such as easy installation, uniform stress distribution, and excellent shock absorption effect. In actual use, each washer part can be replaced independently, and T-type washers of different hardness can be flexibly selected for use as needed to adapt to the installation requirements of different motors.

[0070] The washer structure of this invention solves the problems of installation difficulties, stress concentration, and poor damping effect of traditional I-shaped shock-absorbing washers during motor installation.

[0071] The existing washer structure has the following problems:

[0072] 1. Stringent precision requirements. The asymmetry of the I-beam structure, such as the dimensional difference between the central groove and the two side protrusions, makes it extremely easy for the washer to shift or get stuck when inserted into the motor mounting hole. Motor mounting holes are usually standard round holes, but there may be tiny chamfers or burrs on the edge of the hole. It is difficult for the protruding part of the I-beam washer to match the hole precisely. The operator needs to repeatedly adjust the angle; otherwise, the washer will get stuck at the edge of the hole, causing installation interruption or forced deformation.

[0073] 2. High installation resistance and easy damage. Due to the thin edges and insufficient flexibility of the I-shaped gasket, it is prone to twisting, tearing, or local crushing during insertion due to localized stress concentration. Especially in automated assembly lines, if the robotic arm deviates slightly during gripping, the edge of the gasket is easily scratched by the sharp edge of the orifice, leading to initial seal failure, subsequent vibration leakage or abnormal noise, and even accelerated gasket aging.

[0074] 3. Low production efficiency and high cost. In mass production scenarios, the installation of I-beam washers requires precise manual operation, increasing the installation time per unit by an average of over 30%. Operators need to use specialized tools for alignment, such as tapered push rods, but improper use of these tools can exacerbate the risk of deformation. This not only prolongs the assembly cycle but also significantly increases the rework rate, directly driving up manufacturing costs and affecting the overall delivery schedule of the motor.

[0075] The washer structure of this invention, through the adoption of a combined shock-absorbing washer assembly structure, makes washer installation more convenient and can effectively align the mounting holes; through the double-layer cylindrical structure and wave-shaped annular groove design of the large T-shaped soft rubber washer, the washer has good deformation adaptability and buffering performance; through the hemispherical protrusion structure of the second end face of the first body 1, the friction and shock absorption capacity between the washer and the mounting surface are enhanced; through the single-layer wave structure of the small T-shaped hard rubber washer and the asymmetrical wave concave-convex fit of the large T-shaped soft rubber washer, multi-point contact is achieved, preventing washer rotation and reducing stress concentration; through the screw connector, the motor is fixed to the mounting surface of the whole machine, so that a soft contact is formed between the motor bracket and the mounting surface, thereby achieving a good shock absorption effect.

[0076] This invention proposes a combined washer structure, comprising a large T-shaped soft rubber washer and a small T-shaped hard rubber washer. The large T-shaped soft rubber washer has a double-layered cylindrical vertical portion with an internal corrugated annular groove, and a hemispherical protrusion on its horizontal portion. The small T-shaped hard rubber washer has a single-layered corrugated cylindrical vertical portion, with its corrugations asymmetrically matching the corrugations of the soft washer. Furthermore, the number of corrugations in the soft washer is an integer multiple of the number in the hard washer. This structure achieves the technical advantages of convenient installation, uniform stress distribution, and excellent vibration damping.

[0077] This invention proposes a modular washer structure with the following advantages: 1. It adopts a modular, detachable design, solving the problem of difficulty in installing I-beam type shock-absorbing washers into motor mounting holes. Each washer part can be replaced independently to adapt to the installation requirements of different motors.

[0078] 2. Large T-shaped soft rubber washer: The vertical part of the large T-shaped soft rubber washer is a double-layered cylindrical shape with an internal wavy annular groove. The annular surface of the horizontal part has several unevenly distributed small hemispherical protrusions to further improve the shock absorption effect.

[0079] 3. Small T-shaped hard rubber washer: The vertical part of the small T-shaped hard rubber washer is a single-layer cylindrical shape with wavy inner and outer walls. The number of wavy lines in the soft washer is an integer multiple of that in the hard washer.

[0080] 4. An asymmetrical waveform design is adopted to achieve multi-point contact, prevent rotation, reduce stress concentration, and provide directional damping effect by making the heights of the crests and troughs inconsistent.

[0081] The present invention also provides an electric motor, including the washer structure described above.

[0082] In some embodiments, the motor 15 has multiple legs 17, and the motor 15 is mounted on a mounting plate 13 via the legs 17. The mounting plate 13 is provided with a boss 14. The first part matches the boss 14. The legs 17 are provided with motor mounting holes. The second part passes through the motor mounting holes and is inserted into the first part. The fastener 16 passes through the first through hole 4 and the second through hole 10 and is fixedly connected to the boss.

[0083] During installation, the motor of this invention is first inserted vertically into the lower end face of the motor mounting foot 17, with the first end face of the first main body 1 facing the load volute mounting plate 13 and aligned with the small mounting boss 14 of the volute motor. Then, the single-layer cylinder of the small T-shaped hard rubber washer is fitted between the double-layer cylinders of the large T-shaped soft rubber washer, ensuring a proper corrugated fit. Finally, an Allen screw is used to pass through the center of the two washers to fix the motor 15 onto the load volute mounting plate 13. At this point, there is soft contact between the motor mounting foot, the screw, and the load volute mounting plate, effectively achieving vibration damping.

[0084] In some embodiments, the boss 14 is provided with a screw hole, and the fastener is a screw, which passes through the first through hole 4 and is connected to the second through hole 10 in the screw hole.

[0085] In some embodiments, the mounting plate 13 in the motor of the present invention is a motor mounting part in one example. Specifically, depending on the actual installation position of the motor, a boss 14 or other structure can be provided on the mounting surface of the motor to fix the motor.
