Technical Field
The invention belongs to the technical field of motors, and particularly relates to a damping ring assembly and a motor with the same.
Background
When the motor works, the motor needs to rotate continuously, and the rotation can cause vibration and noise. In order to reduce noise and absorb shock, a damping ring is usually provided inside the motor.
The damping ring is generally installed to current motor, and the damping ring passes through the tight fit to be fixed on the motor, and its main function is when avoiding the motor operation, will shake and transmit to the load, causes the noise problem, also can guarantee the mounting dimension of motor simultaneously, strengthens the commonality of same money motor.
Generally, the appearance of the damping ring is mainly determined by load, and the appearance of the load is slightly changed, such as the change of the installation direction, the change of the installation axial length and the like, so that the existing damping ring cannot be used. In general, the die needs to be redesigned to manufacture a new damping ring. This increases the process and labor costs.
The invention designs a damping ring assembly with better universality in a motor, and the damping ring assembly can not be replaced when only the appearance of a load changes.

In view of the above technical problems in the prior art, an object of the present invention is to design a damping ring assembly, which can solve the problem of the universality of the existing damping ring under the condition of insubstantial load change, and the problem that the damping effect is not optimal because the existing damping ring is only fixed by a tight fit to ensure the reliable fixation with the motor.
The invention also aims to provide a motor, and the damping ring assembly is arranged on the motor.
In order to achieve the above purpose, the present invention adopts the following technical scheme.
The invention provides a damping ring assembly which comprises an upper rubber ring and a lower rubber ring, wherein the upper rubber ring and the lower rubber ring respectively comprise a central hole, an upper surface, a lower surface and an outer surface.
The central holes of the upper rubber ring and the lower rubber ring are coaxially arranged and have the same size. And the outer surfaces of the upper rubber ring and the lower rubber ring are respectively provided with corresponding angle matching marks. The lower surface of the upper rubber ring and the upper surface of the lower rubber ring are respectively provided with a protrusion and a groove which are matched with each other and are distributed uniformly.
Furthermore, the damping ring assembly further comprises a rubber ring, and an assembling hole matched with the protrusion is formed in the rubber ring. The damper ring assembly may include one or more rubber rings.
Furthermore, the upper surface of the upper rubber ring is also provided with an angle matching mark.
Further, the protrusion is slightly larger than the groove, i.e. the two are in interference fit.
Further, the shape of the protrusion may be a cylinder, a triangular column, a square column, an irregular polygonal column, or the like. The corresponding shapes of the groove and the assembling hole are round, triangular, square, irregular polygon and the like.
Further, the number of the grooves is equal to or more than the number of the protrusions.
Furthermore, the upper rubber ring, the rubber ring and the lower rubber ring can be made of rubber with different hardness. When the damping ring assembly does not comprise a rubber ring, the upper rubber ring and the lower rubber ring can be made of rubber with different hardness. In practice, the lower rubber ring with lower hardness can be adopted to be matched with the upper rubber ring with higher hardness (the specific hardness matching is based on the difference value between the actual load and the natural frequency of the used rubber ring), namely, the hardness of the upper rubber ring is greater than that of the lower rubber ring, so that the damping ring assembly has better damping effect. The upper rubber ring with lower hardness can also be adopted to be matched with the lower rubber ring with higher hardness, namely, the hardness of the lower rubber ring is greater than that of the upper rubber ring, so that the damping ring assembly can achieve the same damping effect.
The invention further provides a motor, and the motor is provided with the damping ring assembly.
When the motor is assembled, the lower surface of the lower rubber ring is matched with the end cover of the motor. The upper surface of the lower rubber ring is matched with the rubber ring, the assembling holes on the rubber ring are aligned with the bulges or the grooves of the lower rubber ring for assembly, and the length in the axial direction can be adjusted by adjusting the number of the rubber rings. And installing an upper rubber ring on the rubber ring, and aligning and assembling the groove or the bulge of the upper rubber ring and the bulge or the groove of the lower rubber ring according to the corresponding angle.
In the invention, the damping ring assembly is installed at any angle by matching the protrusion and the groove between the upper rubber ring and the lower rubber ring. The bulges and the grooves are uniformly and regularly arranged on the upper rubber ring or the lower rubber ring, the number of the grooves is equal to or more than that of the bulges, and when any one bulge is matched with any one groove, other bulges can be matched with other corresponding grooves. Therefore, when the upper rubber ring rotates by an angle occupied by the bulge, the upper rubber ring and the lower rubber ring can be matched together; when the upper rubber ring rotates by an angle occupied by two or more protrusions, the upper rubber ring and the lower rubber ring can also be matched together. Thus, the upper rubber ring and the lower rubber ring can be installed by rotating the angle occupied by one or more protrusions. The upper surface and the outer surface of the upper rubber ring are both provided with angle matching marks, and the outer surface of the lower rubber ring is provided with angle matching marks. According to the change of the angles and the positions of the marks, the rotation angle of the load can be known. Through the reasonable shape and distribution of the design protrusion and the groove, the damping ring assembly can obtain excessive matching angles, so that the requirement of the change of the matching angles of the upper rubber ring and the lower rubber ring of the damping ring assembly when the load matching angle changes is met.
In practice, both can set up the arch on last rubber ring, set up the recess on rubber ring down, also can set up the recess on last rubber ring, set up the arch on rubber ring down.
Meanwhile, in the invention, the lower rubber ring is matched with a thinner rubber ring (the thickness is usually 1-2mm) and then matched with the upper rubber ring, so that any axial installation size is realized. The number of the rubber rings can be changed, so that the damping ring assembly can be installed at any angle and at any axial length, and the universality is improved. Moreover, by adopting the damping ring assembly, the natural frequency of the damping ring assembly can be changed, the vibration is reduced, and the damping effect is further enhanced.
The upper rubber ring, the rubber ring and the lower rubber ring with different hardness can be used for combining the damping ring assembly. This kind of damping ring subassembly, hardness structure that is little slightly has better inhaling the shake effect, and hardness structure that is big slightly can provide intensity, like this, can strengthen the shock attenuation effect, structural strength when guaranteeing the motor operation again guarantees the security.
The invention has the following beneficial effects:
1. the damping ring assembly can be used for randomly changing the installation angle on the premise of not reducing the production efficiency.
2. At least two rubber rings with different hardness can be used for matching to enhance the damping effect.
3. Various rubber rings are freely combined and matched with different loads, so that the production cost is reduced, and the production efficiency is improved.

The outer surfaces of the upper rubber ring 1 and the lower rubber ring 2 are provided with corresponding angle matching marks 4. The lower surface of the upper rubber ring 1 and the upper surface of the lower rubber ring 2 are respectively provided with a protrusion 6 and a groove 5 which are matched with each other and are distributed evenly. The projection 6 is slightly larger than the recess 5, i.e. an interference fit. The shape of the protrusion 6 can be a cylinder, a triangular column, a square column, an irregular polygonal column, and the like. The corresponding shape of the groove 5 is round, triangular, square, irregular polygon and the like. The number of said grooves 5 is equal to or greater than the number of projections 6.

Thus, when the upper rubber ring 1 rotates by an angle (about 30 degrees) occupied by the bulge 6, the upper rubber ring 1 and the lower rubber ring 2 can be matched together; when the upper rubber ring 1 rotates by an angle (about 60 degrees) occupied by the two bulges, the upper rubber ring 1 and the lower rubber ring 2 can also be matched together. Thus, the upper rubber ring 1 and the lower rubber ring 2 can be installed at an angle occupied by rotating one or more protrusions 6. The upper surface and the outer surface of the upper rubber ring 1 are both provided with angle matching marks 4, and the outer surface of the lower rubber ring 2 is provided with angle matching marks 4. After the upper rubber ring 1 rotates, the load can be known by the rotation angle according to the position between the angle matching marks 4 of the upper rubber ring 1 and the lower rubber ring 2. In this embodiment, the angle of rotation between the upper and lower rubber rings 2, 2 is 30 ° or a multiple thereof (clockwise, and less than 360 °).
The lower rubber ring 2 is matched with a thinner rubber ring 3 (the thickness is usually 1-2mm), and then is matched with the upper rubber ring 1, so that any axial installation size is realized. The number of glue rings 3 may vary.
Example 2
The damping ring assembly of the present embodiment is different from embodiment 1 in that the upper rubber ring 1 is provided with protrusions 6, and the lower rubber ring 2 is provided with grooves 5.
Thus, the upper rubber ring 1, the rubber ring 3 and the lower rubber ring 2 are combined together, and the installation at any angle of rotation and the installation at any length of the axial direction can be realized.
