[0039] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.
[0040] In the related art, dynamic balance adjustment of the impeller is performed by mounting a balance clip on the blade of the impeller. The balance clip not only increases the cost of the impeller, but also has the risk of failure caused by the balance clip falling off.
[0041] The impeller of the embodiment of the present disclosure reduces the risk of failure caused by the falling of parts by setting a balance adjustment area on the impeller and adjusting the balance of the impeller through the balance adjustment area without increasing the cost of the impeller.
[0042] As shown in Figures 1 to 5 The impeller 100 of the embodiment of the present disclosure includes a plurality of blades 2 and at least two balance adjustment areas, the balance adjustment areas are arranged between adjacent two blades 2 or on the blades 2, and the balance adjustment areas are provided with balance adjustment portions 3 or balance notches.
[0043] The impeller 100 of the embodiment of the present disclosure realizes dynamic balance adjustment of the impeller 100 by setting the balance adjustment areas between adjacent two blades 2 or on the blades 2 and providing the balance adjustment areas with the balance adjustment portions 3 or the balance notches. Not only can the cost of the impeller 100 be reduced by avoiding the additional setting of the components for dynamic balance adjustment of the impeller 100, but also the risk of failure caused by the falling of the balance adjustment portions 3 can be reduced. Thus, the cost of the impeller 100 can be reduced and the reliability of the impeller 100 can be improved.
[0044] In some embodiments, the balance notches are formed by removing the balance adjustment portions 3.
[0045] For example, when the impeller 100 is dynamically balanced, the balance adjustment portions 3 can be removed as needed to realize the balance adjustment of the impeller 100. The balance adjustment portions 3 can be manually snapped off or cut off by an auxiliary tool.
[0046] It should be noted that before the impeller 100 is dynamically balanced, the balance adjustment portions 3 are integrally connected with the blades 2, at this time, the impeller 100 has the balance adjustment portions 3. During the dynamic balance adjustment of the impeller 100, part of the balance adjustment portions 3 is removed as needed, at this time, the impeller 100 has the balance adjustment portions 3 and the balance notches 43, or all of the balance adjustment portions 3 are removed, at this time, the impeller 100 has no balance adjustment portions 3 and only has the balance notches 43.
[0047] Optionally, the weight of the balance adjustment portion 3 is 0.3g-0.6g.
[0048] For example, the weight of the balance adjustment portion 3 is 0.5g.
[0049] When the weight of the balance adjustment portion 3 is light, the dynamic balance of the impeller 100 is less affected by the removal of the balance adjustment portion 3, which is not conducive to the rapid dynamic balance adjustment of the impeller 100; when the weight of the balance adjustment portion 3 is heavy, the dynamic balance of the impeller 100 is greatly affected by the removal of the balance adjustment portion 3, which is also not conducive to the rapid dynamic balance adjustment of the impeller 100.
[0050] By setting the weight of the balance adjusting part 3 to 0.3g-0.6g, the weight of the balance adjusting part 3 is not too light or too heavy, and the dynamic balance adjusting efficiency of the impeller 100 is improved.
[0051] Optionally, as shown in Figure 1 and Figure 3 , the impeller 100 further comprises an impeller body 1, the blade 2 is connected with the impeller body 1, the balance adjusting part 3 is connected with at least one of the impeller body 1 and the blade 2 through the weakening part 4, and the weakening part 4, the balance adjusting part 3 and the at least one are integrally formed.
[0052] Among them, the structural strength of the weakening part 4 is lower than the strength of the balance adjusting part 3 and the at least one, so as to disconnect the connection between the balance adjusting part 3 and the at least one at the weakening part 4, and remove the balance adjusting part 3 from the at least one.
[0053] By setting the weakening part 4, the balance adjusting part 3 is removed from the at least one, so as to further improve the dynamic balance adjusting efficiency of the impeller 100.
[0054] In some embodiments, as shown in Figure 2 , the weakening part 4 is a thinning part 41, and the thickness of the thinning part 41 is less than the thickness of the balance adjusting part 3 and the at least one.
[0055] For example, as shown in Figure 2 , the balance adjusting part 3 is arranged on the impeller body 1, the thickness of the thinning part 41 is L1, the thickness of the balance adjusting part 3 is L2, the thickness of the impeller body 1 is L3, and L1 is less than L2 and L3.
[0056] The thickness of the thinning part 41 is set to be less than the thickness of the balance adjusting part 3 and the at least one, so that the structural strength of the weakening part 4 is lower than the strength of the balance adjusting part 3 and the at least one, thereby facilitating the disconnection of the connection between the balance adjusting part 3 and the at least one at the weakening part 4.
[0057] By setting the weakening part 4 as the thinning part 41, the structure of the weakening part 4 is simple, and the processing and manufacturing of the impeller 100 are facilitated.
[0058] Optionally, the thinning part 41 is formed by forming a groove 42 on the at least one.
[0059] For example, as shown in Figure 2 , the balance adjusting part 3 is arranged on the impeller body 1, and the thinning part 41 is formed by forming a groove 42 on the impeller body 1. Among them, the balance adjusting part 3 is connected with the impeller body 1 through the groove bottom wall of the groove 42.
[0060] The thinning portion 41 is formed by forming the groove 42 on the at least one, facilitating the formation of the thinning portion 41, and further facilitating the machining and manufacturing of the impeller 100.
[0061] In addition, when the balancing adjusting portion 3 is cut by a tool, the tool can extend into the interior of the groove 42, i.e., the position of the tool is limited by the groove 42, so as to quickly remove the balancing adjusting portion 3, and further improve the dynamic balancing adjusting efficiency of the impeller 100. The tool can be a sculptured tool or a pliers, etc.
[0062] In other embodiments, the thickness of the thinning portion 41 can also be gradually changed, for example, the thickness of the thinning portion 41 gradually decreases along the direction away from the center of the balancing adjusting portion 3, so that the thickness of the thinning portion 41 at the connection with the at least one is the smallest, and the thickness of the thinning portion 41 at the connection with the balancing adjusting portion 3 is the largest. At this time, the thinning portion 41 does not form a groove on the at least one.
[0063] In other embodiments, the weakening portion 4 includes a plurality of connection strips, two adjacent connection strips are arranged at intervals, the connection strips are connected between the balancing adjusting portion 3 and the at least one, and the connection strips, the balancing adjusting portion 3 and the at least one are integrally formed.
[0064] For example, the balancing adjusting portion 3 is arranged on the impeller body 1, and the balancing adjusting portion 3 and the impeller body 1 are connected by a plurality of connection strips. The structural strength of the connection strips is lower than that of the balancing adjusting portion 3 and the at least one, so as to facilitate the disconnection of the balancing adjusting portion 3 and the at least one at the weakening portion 4.
[0065] By arranging the weakening portion 4 to include a plurality of connection strips, the structural strength of the weakening portion 4 is relatively weak, facilitating the removal of the balancing adjusting portion 3 from the at least one, and further improving the dynamic balancing adjusting efficiency of the impeller 100.
[0066] Optionally, a plurality of through holes are formed between the balancing adjusting portion 3 and the at least one, and a connection strip is formed between two adjacent through holes.
[0067] For example, the balancing adjusting portion 3 is arranged on the impeller body 1, and the part between the balancing adjusting portion 3 and the impeller body 1 has a plurality of through holes, and a connection strip is formed between adjacent through holes.
[0068] By forming a plurality of through holes between the balancing adjusting portion 3 and the at least one, and forming a connection strip between two adjacent through holes, the formation of the connection strip is facilitated, and the machining and manufacturing of the impeller 100 are facilitated.
[0069] In other embodiments, the balancing adjusting portion 3 and the at least one are connected by a breakpoint structure, and the breakpoint structure forms the weakening portion 4.
[0070] In some embodiments, the balancing adjusting portion is arranged on the impeller body 1.
[0071] The geometry of the blade 2 affects the performance of the impeller 100, and if the balance adjustment region is arranged on the blade 2, the geometry of the blade 2 will change before and after the balance adjustment part 3 is removed, thereby affecting the performance of the impeller 100.
[0072] By arranging the balance adjustment part 3 on the impeller body 1, the influence of the balance adjustment part 3 on the performance of the impeller 100 before and after the balance adjustment part 3 is removed can be avoided, thereby facilitating the guarantee of the performance of the impeller 100.
[0073] In some embodiments, the impeller body 1 includes a hub 11, and the balance adjustment region is arranged on the hub 11.
[0074] The hub 11 of the impeller 100 mainly plays a supporting role, and the structural strength is usually good. By arranging the balance adjustment region on the hub 11, the influence of the balance adjustment part 3 on the structural strength of the impeller body 1 can be reduced, thereby facilitating the guarantee of the structural strength of the impeller 100 and the reliability of the impeller 100.
[0075] In other embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the impeller body 1 includes a hub 11 and a connecting ring 12, a plurality of blades 2 are uniformly and spaced apart around the circumference of the hub 11, the first end 21 of the blade 2 is connected to the hub 11, the second end 22 of the blade 2 is connected to the connecting ring 12, and the balance adjustment region is arranged on at least one of the hub 11 and the connecting ring 12.
[0076] The balance adjustment region arranged on at least one of the hub 11 and the connecting ring 12 can be understood as: the balance adjustment region is arranged only on the hub 11, i.e., only the hub 11 is provided with the balance adjustment region; or the balance adjustment region is arranged only on the connecting ring 12, i.e., only the connecting ring 12 is provided with the balance adjustment region; or the balance adjustment region is arranged on both the hub 11 and the connecting ring 12, i.e., both the hub 11 and the connecting ring 12 are provided with the balance adjustment region.
[0077] By arranging the balance adjustment region on at least one of the hub 11 and the connecting ring 12, the influence of the balance adjustment region on the performance of the impeller 100 before and after the balance adjustment region is removed can be avoided, thereby facilitating the guarantee of the performance of the impeller 100.
[0078] Optionally, as shown in Figure 3 , the hub 11 includes a cylinder body 111, one end of the cylinder body 111 provided with a flange 112, the first end 21 of the blade 2 is connected to the flange 112, and the balance adjustment region is arranged on the flange 112.
[0079] The flange 112 is arranged close to the radial outer side of the hub 11. By arranging the balance adjusting area on the flange 112, the balance adjusting area can be removed conveniently when dynamic balance adjustment is performed, so as to further improve the dynamic balance adjustment efficiency of the impeller 100.
[0080] Optionally, as shown in Figure 2 the outer periphery of the balance adjusting area is located inward of the outer periphery of the flange 112, or the outer periphery of the balance adjusting area is flush with the outer periphery of the flange 112.
[0081] By arranging the outer periphery of the balance adjusting area inward of the outer periphery of the flange 112, or arranging the outer periphery of the balance adjusting area flush with the outer periphery of the flange 112, the outer periphery of the balance adjusting area can be prevented from protruding outward of the outer periphery of the flange 112. In this way, the arrangement of the balance adjusting area can be prevented from affecting the outer periphery contour of the hub 11, the performance of the impeller 100 is reduced, and the performance of the impeller 100 is facilitated to be ensured.
[0082] Optionally, as shown in Figure 2 the balance adjusting part 3 is formed by arranging a groove 42 on the end surface of the flange 112.
[0083] By arranging the groove 42 on the end surface of the flange 112 to form the balance adjusting part 3, the formation of the balance adjusting part 3 is facilitated, and the machining and manufacturing of the impeller 100 are further facilitated.
[0084] When the balance adjusting part 3 is removed by a tool, the tool can be inserted into the interior of the groove 42, i.e. the position of the tool is limited by the groove 42, so as to remove the balance adjusting part 3 quickly, and the dynamic balance adjustment efficiency of the impeller 100 is further improved.
[0085] In some embodiments, as shown in Figure 2 the groove 42 is U-shaped, and the groove 42 is open outward in the radial direction of the flange 112.
[0086] By arranging the groove 42 in the above form, the balance adjusting part 3 can be removed by a tool on the radial outer side of the flange 112, and the dynamic balance adjustment efficiency of the impeller 100 is further improved.
[0087] In other embodiments, the groove 42 is an annular groove, and the annular groove surrounds the balance adjusting part 3.
[0088] The groove 42 can be a rectangular groove, a circular groove, a triangular groove, a rhombic groove, a hexagonal groove, etc.
[0089] By arranging the groove 42 as an annular groove, the position of the tool can be limited by the groove 42, so as to remove the balance adjusting part 3 quickly, and the dynamic balance adjustment efficiency of the impeller 100 is further improved.
[0090] Optionally, as shown in Figure 1 , Figure 3 and Figure 4 , a plurality of blades 2 are arranged at intervals along the circumference of the impeller body 1, and the balance adjusting part 3 is arranged between any two adjacent blades 2.
[0091] By arranging the balance adjusting part 3 between any two adjacent blades 2, the balance adjusting part 3 can be avoided from interfering with the blades 2, facilitating the layout design of the balance adjusting part 3, thereby facilitating the design and manufacture of the impeller 100.
[0092] Of course, in other embodiments, the balance adjusting part 3 can also be arranged radially inward of the blades 2.
[0093] Optionally, as shown in Figure 1 , Figure 3 and Figure 4 , the balance adjusting part 3 is arranged between any two adjacent blades 2.
[0094] By arranging the balance adjusting part 3 between any two adjacent blades 2, it is convenient to remove the balance adjusting part 3 at the corresponding position as needed, so as to quickly realize the dynamic balance of the impeller 100, and further improve the dynamic balance adjusting efficiency of the impeller 100.
[0095] Optionally, as shown in Figure 1 , Figure 3 and Figure 4 , the balance adjusting part 3 and the blade 2 are alternately and interval arranged along the circumference of the hub 11.
[0096] For example, the balance adjusting part 3 and the blade 2 are alternately and interval arranged along the circumference of the hub 11.
[0097] By alternately and interval arranging the balance adjusting part 3 and the blade 2 along the circumference of the hub 11, it is convenient to process and manufacture the impeller 100, which is beneficial to reduce the cost of the impeller 100.
[0098] The impeller 100 of the embodiment of the present disclosure, by arranging the balance adjusting area, and the balance adjusting area being provided with the balance adjusting part 3 or the balance gap 43, after the dynamic balance test is performed on the impeller 100, the balance adjusting part 3 at the corresponding position can be removed by using a profile tool or a pliers and the like, so as to achieve the required balance of the impeller 100 by means of weight reduction of the impeller 100. Not only the cost of the impeller 100 is reduced without additional balance clips and the like, but also the failure problem caused by the balance adjusting part 3 being separated from the impeller 100 is avoided, and the reliability of the impeller 100 is improved.
[0099] The fan of the embodiment of the present disclosure comprises a fan shell and the impeller 100, the impeller 100 being the impeller 100 of any of the above embodiments, and the impeller 100 being arranged inside the fan shell.
[0100] Wherein, before the impeller 100 is installed into the fan shell, the impeller 100 can be dynamically balanced, that is, the dynamic balance of the impeller 100 is achieved by removing the balance adjusting part 3 at the corresponding position.
