Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a motor vibration reduction installation structure. Background Art

[0002] For motors with upper and lower shells locked and installed, the existing motor installation method is usually to directly connect and fix the motor on the shell. The motor is in contact with the shell, and the vibration is transmitted to the shell when the motor rotates, which is prone to resonance and leads to increased noise and vibration.

[0003] In order to reduce vibration, when installing the motor, it is usually locked to the housing with screws directly or through rubber pads, or buffered by a shock-absorbing ring. Since the cross-section of the shock-absorbing ring is circular, the thickness of the shock-absorbing ring becomes much smaller after assembly and compression, and the shock-absorbing effect will be greatly reduced; and because there are dimensional tolerances on the outer body of the motor, the thickness of the shock-absorbing ring after compression is different around the housing, and the shock-absorbing effect in each direction is different, and the shock-absorbing effect is unstable. Summary of the invention

[0004] The purpose of the utility model is to provide a motor damping installation structure to solve the problems raised in the above background technology. To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A motor damping installation structure comprises a housing, a damping ring and a motor installed in the housing; the damping ring is arranged between the housing and the motor; and the cross section of the damping ring is rectangular.

[0006] Furthermore, the inner wall of the shell is provided with a mounting groove, and the shock absorbing ring is installed in the mounting groove.

[0007] Furthermore, the width of the notch of the mounting groove close to the motor is greater than the width of the shock absorbing ring.

[0008] Further, the shell includes a first shell and a second shell, and the inner wall of the first shell and the inner wall of the second shell are respectively provided with installation grooves; the shock-absorbing ring includes a first half ring and a second half ring, the first half ring is installed in the installation groove of the inner wall of the first shell, and the second half ring is installed in the installation groove of the inner wall of the second shell.

[0009] Furthermore, the motor shock-absorbing mounting structure also includes a shock-absorbing pad arranged on the motor and having one end of the motor shaft, and the outer periphery of the shock-absorbing pad is provided with an inner groove; a limiting portion is provided in the outer shell, and the limiting portion is engaged in the inner groove.

[0010] Furthermore, the motor has a threaded hole at one end of the motor shaft, and the shock-absorbing pad is axially provided with a connecting hole, through which a screw passes through the connecting hole and is screwed to the threaded hole to achieve fixed connection between the shock-absorbing pad and the motor.

[0011] The beneficial effect of the utility model is that the utility model sets the cross-section of the shock-absorbing ring to a rectangle, which can increase the contact area between the shock-absorbing ring and the motor and the housing on the one hand, and on the other hand, the thickness of the shock-absorbing ring after being pressed by the motor and the housing changes little, which can retain a longer buffer distance and ensure a good shock-absorbing effect, thereby making the shock-absorbing effect of the motor shock-absorbing mounting structure better and more stable.

[0025] like Figures 1 to 3 As shown, a motor shock-absorbing installation structure includes a housing 1, a shock-absorbing ring 2 and a motor 3 installed in the housing 1; the shock-absorbing ring 2 is arranged between the housing 1 and the motor 3; the cross-section of the shock-absorbing ring 2 is rectangular.

[0026] As an example, the shock absorbing ring 2 is wrapped around the outside of the motor 3, and the outside of the shock absorbing ring 2 contacts the inner wall of the housing 1, so that the shock absorbing ring 2 is pressed between the housing 1 and the motor 3, playing a role of shock absorption and buffering, and reducing the vibration generated by the motor 3 during operation from being transmitted to the housing 1. At the same time, compared with the shock absorbing ring 2 of the prior art with a circular cross section, since the cross section of the shock absorbing ring 2 is rectangular, on the one hand, the shock absorbing contact area of ​​the shock absorbing ring 2 is relatively large, and the shock absorbing effect is better and more stable; on the other hand, after the shock absorbing ring 2 is pressed by the motor 3 and the housing 1, the thickness of the shock absorbing ring 2 changes little, so a longer buffer distance can be retained to ensure a good shock absorbing effect.

[0027] In one embodiment, a mounting groove 101 is provided on the inner wall of the housing 1 , and the shock absorbing ring 2 is installed in the mounting groove 101 .

[0028] As an example, the bottom of the mounting groove 101 is adapted to the shape of the shock-absorbing ring 2, so that the shock-absorbing ring 2 is embedded and clamped in the mounting groove 101 to prevent the shock-absorbing ring 2 from loosening, and the shock-absorbing ring 2 is fit with the bottom of the mounting groove 101 to ensure the contact area between the shock-absorbing ring 2 and the outer shell 1, thereby achieving a stable shock-absorbing effect.

[0029] In one embodiment, see Figure 1 and Figure 3 The width of the slot of the mounting slot 101 close to the motor 3 is greater than the width of the damping ring 2 .

[0030] As an example, the width of the slot of the installation slot 101 close to the motor 3 is greater than the width of the shock-absorbing ring 2, so that a certain gap is retained between the installation slot 101 and the shock-absorbing ring 2, which is used to reserve a certain compression space for the shock-absorbing ring 2. After being pressed by the motor 3 and the housing 1, the shock-absorbing ring 2 is deformed and filled in the gap, which can also increase the contact area between the shock-absorbing ring 2 and the motor 3, making the shock-absorbing effect more stable.

[0031] In one embodiment, the housing 1 includes a first shell 11 and a second shell 12, and the inner walls of the first shell 11 and the second shell 12 are respectively provided with mounting grooves 101; the shock-absorbing ring 2 includes a first half ring 21 and a second half ring 22, the first half ring 21 is installed in the mounting groove 101 on the inner wall of the first shell 11, and the second half ring 22 is installed in the mounting groove 101 on the inner wall of the second shell 12.

[0032] As an example, the installation groove on the inner wall of the first shell 11 and the installation groove on the inner wall of the second shell 12 are connected to each other to form a circle, so that the first half ring 21 and the second half ring 22 can be connected to form a relatively closed circle when installed therein. When assembling the motor shock-absorbing installation structure of this embodiment, the first half ring 21 and the second half ring 22 are pre-installed in the first shell 11 and the second shell 12 respectively, so that the first half ring 21 and the second half ring 22 are respectively embedded and clamped in the corresponding installation groove 101; then the first shell 11 and the second shell 12 are covered, fixed and locked, at which time the first half ring 21 and the second half ring 22 are connected to form a relatively closed circle and wrapped around the outer periphery of the motor 3 to achieve the shock-absorbing effect. The shock-absorbing ring 2 of the present embodiment is composed of two split half rings, which is convenient for directly pre-installing the two half rings into the corresponding installation grooves 101 accurately, and the operation is simple and convenient; while when installing the one-piece circular shock-absorbing ring 2 structure of the prior art, it is necessary to first put the shock-absorbing ring 2 on the motor 3, and then clamp one side of the shock-absorbing ring 2 into the installation groove 101 of a shell. Finally, when closing the other shell, it is difficult to make the other side of the shock-absorbing ring 2 accurately clamped in the corresponding installation groove 101. The present embodiment solves this problem.

[0033] In one embodiment, the motor shock-absorbing mounting structure also includes a shock-absorbing pad 4 arranged on the motor 3 and having one end of the motor 3 shaft, and the outer periphery of the shock-absorbing pad 4 is provided with an inner groove 401; a limiting portion 102 is provided in the outer shell 1, and the limiting portion 102 is engaged in the inner groove 401.

[0034] As an example, the shock-absorbing pad 4 is fixedly connected to the motor 3 and has one end of the motor 3 shaft. When the motor 3 is installed in the housing 1, the inner groove 401 of the shock-absorbing pad 4 is aligned with the limiting portion 102 in the housing 1, so that the limiting portion 102 and the inner groove 401 are snap-fitted and fastened, which can not only play a shock-absorbing role, but also limit the forward and backward movement of the motor 3 along the direction of the motor 3 axis during operation, making the motor 3 more stable.

[0035] In one embodiment, see Figure 4 The motor 3 has a threaded hole 301 at one end of the motor 3 shaft, and the shock-absorbing pad 4 has a connecting hole 402 axially opened, through which a screw 5 passes through the connecting hole 402 and is screwed to the threaded hole 301 to achieve a fixed connection between the shock-absorbing pad 4 and the motor 3.

[0036] As an example, before the motor 3 is installed into the housing 1, the screw 5 is first passed through the connecting hole 402 of the shock-absorbing pad 4, and then the screw 5 is screwed and fastened with the threaded hole 301 on the motor 3 to achieve the assembly and fixation of the shock-absorbing pad 4 and the motor 3. Finally, the motor 3 is assembled with the housing 1. The connection between the shock-absorbing pad 4 and the motor 3 is fixed and not easy to loosen, thereby ensuring the stable shock-absorbing effect.

[0037] Regarding the embodiments of the present utility model, it should also be noted that, in the absence of conflict, the embodiments of the present utility model and the features therein can be combined with each other to obtain new embodiments.
