[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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 utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model. The directional terms "inner" and "outer" refer to the inner and outer contours 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 cannot be construed as limiting the scope of protection of this utility model.

[0035] This utility model provides a rotating shaft bracket and a motor, which can solve the technical problem of low installation efficiency between the motor and the bracket in the prior art.

[0036] See also Figure 1-12As shown, this utility model provides a rotating shaft bracket for supporting a rotating shaft 1. The rotating shaft bracket includes a first vibration damping component and a base 2. The first vibration damping component is sleeved on the rotating shaft 1. The base 2 includes a first support plate 201. The first support plate 201 is provided with a mounting groove 203 that penetrates its own surface. The mounting groove 203 has an upward-facing mounting opening. The inner wall of the mounting groove 203 is provided with a retaining groove 6. The first vibration damping component includes a vibration damping ring 5 directly sleeved on the rotating shaft 1 and a retaining spring 4 sleeved on the vibration damping ring 5. The retaining spring 4 includes a C-shaped elastic segment 401. Both ends of the elastic segment 401 are respectively provided with mounting protrusions 402 protruding away from the rotating shaft 1. When the elastic segment 401 is engaged in the mounting groove 203, the mounting protrusions 402 can be engaged in the retaining groove 6.

[0037] When supporting the rotating shaft 1, the damping ring 5 is first fitted onto the rotating shaft 1 to dampen vibration. Furthermore, a bearing can be installed between the damping ring 5 and the rotating shaft 1 to reduce friction. Then, the retaining ring 4 is fitted onto the damping ring 5. (Because the retaining ring 4 is elastic, in specific operation, external force is applied to both sides from the opening of the retaining ring 4 to open it, so that the retaining ring 4 fits onto the damping ring 5. The retaining ring 4, under its own elasticity, is tightly fitted onto the damping ring 5.) Then, the C-shaped elastic segment 401 is inserted into the mounting groove 203 from the mounting opening. To prevent the C-shaped elastic segment 401 from falling out of the mounting opening, the mounting protrusion 402 is inserted into the slot 6 to fix the elastic segment 401. Fixing the first damping component by inserting the mounting protrusion 402 into the slot 6 eliminates the need for existing screw fixing, improves the efficiency of supporting and fixing the rotating shaft 1, and is beneficial for improving the degree of automation.

[0038] Furthermore, the surface of the first support plate 201 is substantially perpendicular to the rotating shaft 1.

[0039] Furthermore, the inner wall of the mounting groove 203 is arc-shaped; the vibration damping ring 5 is provided with a shaft hole 3 for fitting onto the rotating shaft 1.

[0040] Furthermore, the damping ring 5 is made of rubber as a rubber ring; the retaining spring 4 is made of steel and has elasticity.

[0041] Preferred, such as Figure 3-6 , Figure 10-11 As shown, in the circumferential direction of the rotating shaft 1, the opening size of the slot 6 is smaller than the inner cavity size of the slot 6; the two mounting protrusions 402 form a V-shape with the opening facing away from the rotating shaft 1.

[0042] By having the opening size of the slot 6 smaller than the inner cavity size of the slot 6 in the circumferential direction of the rotating shaft 1, and the two mounting protrusions 402 forming a flared V-shape facing away from the rotating shaft 1, when the two mounting protrusions 402 are inserted into the slot 6, the mounting protrusions 402 are difficult to dislodge from the slot 6, thus improving the stability of the bracket installation.

[0043] The V-shape is equivalent to a swallowtail shape, with an flare angle α less than 90°.

[0044] Preferred, such as Figure 3-6 , Figure 10-11 As shown, the retaining ring 4 has a first state when it is not subjected to external force and a second state when the two mounting protrusions 402 are squeezed and move closer to each other; the opening size of the retaining groove 6 is L1, when the retaining ring 4 is in the first state, the minimum distance between the relative outer sides of the two mounting protrusions 402 is L2, and when the retaining ring 4 is in the second state, the minimum distance between the relative outer sides of the two mounting protrusions 402 is L3. Therefore, L2 > L1 > L3.

[0045] Since L2 > L1 > L3, when an external force is applied to put the retaining spring 4 in the second state, the mounting protrusion 402 can be inserted into the retaining groove 6. When the external force is removed, the retaining spring 4 is in the first state, and the mounting protrusion 402 can be firmly inserted into the inner cavity of the retaining groove 6.

[0046] Preferred, such as Figure 3-6 , Figure 10-11 As shown, when the retaining ring 4 is in the second state, the maximum distance between the relative outer sides of the two mounting protrusions 402 is L4, where L4 < L1.

[0047] The retaining ring 4 is put into the second state by pressing the mounting protrusions 402 from both sides (the two mounting protrusions 402 are close to each other). Since L1 > L4, the two mounting protrusions 402 of the retaining ring 4 are inserted into the retaining groove 6 from the opening of the retaining groove 6, which improves the convenience of the mounting protrusions 402 being inserted into the retaining groove 6.

[0048] In the axial projection, the inner cavity of the slot 6 is one of the following shapes: rectangular, elliptical, circular, triangular, or trapezoidal. The inner cavity of the slot 6 is preferably rectangular.

[0049] Furthermore, when the snap ring 4 is in the first state, the maximum distance between the relative outer sides of the two mounting protrusions 402 is L5, where L5 > L1.

[0050] Preferred, such as Figure 2-6 As shown, the opening of the slot 6 is provided with a locking head 601 extending close to each other, and at least one end of the retaining spring 4 is provided with a groove or through hole 405 facing the locking head 601. When the mounting protrusion 402 is engaged in the slot 6, the locking head 601 is engaged in the groove or the through hole 405.

[0051] By providing grooves or through holes 405 at both ends of the retaining ring 4, when the mounting protrusion 402 is inserted into the retaining groove 6, the retaining head 601 can be inserted into the groove or through hole 405 to further improve the firmness of the retaining ring 4 in the retaining groove 6, thereby improving the stability and firmness of the support for the rotating shaft 1.

[0052] Preferred, such as Figure 7 As shown, the outer circumferential surface of the damping ring 5 is provided with an annular groove, and the inner circumferential surface of the elastic segment 401 is arc-shaped and fits into the annular groove.

[0053] By providing an annular groove on the outer circumferential surface of the damping ring 5, and making the inner circumferential surface of the retaining spring 4 arc-shaped and fitting into the annular groove, the firmness of the connection between the retaining spring 4 and the damping ring 5 is improved, thereby enhancing the stability of the rotating shaft 1 during rotation.

[0054] In another embodiment, the damping ring 5 is injection molded and wrapped around the snap ring 4 (excluding the mounting protrusion 402).

[0055] Preferred, such as Figure 8-9 As shown, the outer peripheral surface of the elastic segment 401 is provided with a guard edge 403 extending along the axial direction of the rotating shaft 1. In the axial direction, the length of the guard edge 403 is not less than the length of the damping ring 5.

[0056] By setting a protective edge 403 and ensuring that the length of the protective edge 403 is not less than the length of the damping ring 5, the protective plate can provide full support for the damping ring 5, thus preventing uneven pressure on the damping ring 5.

[0057] Preferred, such as Figure 8 As shown, the elastic segment 401 is provided with an annular groove 404 with an opening facing away from the rotating shaft 1. In the axial direction, the width of the annular groove 404 is greater than or equal to the thickness of the first support plate 201, and the first support plate 201 is inserted into the annular groove 404.

[0058] An annular groove 404 is provided on the elastic section 401 and is engaged with the first support plate 201, which prevents the first support plate 201 from cutting the vibration damping ring 5 and ensures the service life of the vibration damping ring 5.

[0059] Preferred, such as Figure 8 As shown, in the axial direction of the rotating shaft 1, the annular groove 404 is located in the middle of the annular groove.

[0060] The annular groove 404 is set in the middle of the annular groove so that when the rotating shaft 1 is subjected to an axial force, the two sides of the damping ring 5 can achieve a relatively balanced damping effect.

[0061] This utility model also provides a motor, including an output shaft and the aforementioned shaft support, wherein the shaft 1 constitutes the output shaft.

[0062] This motor is easy to install and runs stably.

[0063] Furthermore, the motor has an output shaft at each of its axial ends, and the motor also includes a second vibration damping component, which is the same as the first vibration damping component. The first vibration damping component and the second vibration damping component support the two output shafts respectively.

[0064] Furthermore, the base 2 also includes a second support plate 202, which is the same as the first support plate 201. The second support plate 202 and the first support plate 201 are connected together by a connecting plate. The first support plate 201, the second support plate 202 and the connecting plate form a U-shape. This motor has low installation cost and a high degree of automation.

[0065] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
