[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] like Figures 1 to 6As shown, the utility model provides a rotor baffle, which is used to be sleeved on the rotor shaft 100 of the rotor, and the rotor baffle comprises: a baffle body 1, the baffle body 1 is a circular ring structure, a slideway 11 is arranged on the baffle body 1, and the extension track of the slideway 11 is a circular ring track arranged around the central axis of the baffle body 1, and the slideway 11 comprises a connected slot body 111 and an opening 112, and the opening 112 is located on a side of the slot body 111 away from the rotor core 200 of the rotor, and the width of the slot body 111 is large. The balancing slider 2 comprises a pull rod 21 and a base 22, an elastic member 23 and a gasket 24 located in the slide 11. The base 22, the elastic member 23 and the gasket 24 are sequentially sleeved on the pull rod 21. The base 22 is located on the side of the elastic member 23 away from the opening 112. One end of the pull rod 21 is fixedly connected to the base 22, and the other end of the pull rod 21 extends out of the baffle body 1 through the opening 112. The balancing slider 2 is movably arranged relative to the slide 11.

[0035] In this way, the rotor baffle of the utility model is provided with a slideway 11 and a balancing slider 2. It only needs to pull the pull rod 21 to make the base 22 compress the elastic member 23 so as to quickly move the balancing slider 2 to any unbalanced position on the slideway 11, so as to achieve the purpose of dynamic balancing of the rotor, and realize a new dynamic balancing method. It solves the problem that the rotor baffle in the motor in the prior art needs to be provided with a welding ring or a round nut for axial limiting, resulting in more production processes and higher costs for the rotor, solves the problem that the rotor baffle in the motor in the prior art has a threaded hole and uses a copper screw counterweight and has a high dynamic balancing cost, solves the problem that the rotor baffle in the motor in the prior art needs to paste the balancing glue for many times during dynamic balancing due to the uncontrollable amount of balancing glue and the pasting position, and reduces the filling and repeated calibration, which leads to the problem of low efficiency and high cost of balancing work, solves the problem that the dynamic balancing glue in the prior art cannot be used in high-speed motors and there is a risk of falling off, and also solves the problem that the rotor baffle of the motor in the prior art needs a lower speed during dynamic balancing, thereby expanding the application of balancing glue in high-speed motors.

[0036] Preferably, the pull rod 21 is a cylinder, the base 22 and the gasket 24 are both rings, the outer diameter of the base 22 and the outer diameter of the gasket 24 are both smaller than the width of the groove body 111 and larger than the width of the opening 112; and / or the elastic member 23 is a compression spring; and / or there are multiple gaskets 24, and multiple gaskets 24 can be selectively arranged on the pull rod 21 in sequence; and / or there are multiple balancing sliders 2, and multiple balancing sliders 2 are arranged at intervals in the slide 11.

[0037] Among them, the width of the groove body 111 refers to the size of the cross section of the groove body 111 in the radial direction parallel to the baffle body 1, and the width of the opening 112 refers to the size of the cross section of the opening 112 in the radial direction parallel to the baffle body 1; the outer diameter of the base 22 and the outer diameter of the gasket 24 are set to be smaller than the width of the groove body 111 and larger than the width of the opening 112, which can ensure that the base 22, the elastic member 23 and the gasket 24 will not fall off the slide 11.

[0038] The number of gaskets 24 on each balancing slider 2 of the rotor baffle of the utility model can be adjusted to change the weight of the corresponding balancing slider 2. When calibrating the dynamic balance, it is only necessary to quickly and accurately move the balancing slider 2 to the unbalanced position, thereby improving the adjustment efficiency of the dynamic balance.

[0039] Specifically, when performing dynamic balancing, it is first necessary to measure the initial imbalance of the rotor, then adjust the number of gaskets 24 on each balancing slider 2, and finally install each balancing slider 2 into the slideway 11 in turn and move it to a suitable position.

[0040] In addition, the rotor baffle of the utility model is advantageous for adjusting multiple unbalanced positions by arranging multiple balancing sliders 2 in the slideway 11 .

[0041] like Figure 4 In the illustrated embodiment, a spacer 24 is provided on the balancing slider 2 .

[0042] like Figure 5 In the illustrated embodiment, two spacers 24 are provided on the balancing slider 2 .

[0043] like Figure 1 and Figure 2 As shown, a mounting channel 12 is provided on the baffle body 1 , the mounting channel 12 is connected to the slideway 11 and the outer peripheral surface of the baffle body 1 , and the balancing slider 2 is installed in the slideway 11 through the mounting channel 12 .

[0044] Specifically, the elastic member 23 and the gasket 24 are sleeved on the pull rod 21 connected to the base 22, the gasket 24 is pressed to compress the elastic member 23, and then the balancing slider 2 is installed in the slide 11 through the installation channel 12, the pull rod 21 is pulled to compress the elastic member 23, so that the balancing slider 2 moves to an unbalanced position in the slide 11, and the pull rod 21 is loosened to allow the base 22 to be inserted into the groove 13 facing the base 22 under the elastic action of the elastic member 23.

[0045] Preferably, there are a plurality of slideways 11 , which are sequentially spaced apart in a direction away from the central axis of the baffle body 1 , and the mounting channel 12 is connected to each of the slideways 11 .

[0046] like Figures 1 to 6As shown, there are two slides 11, namely a first slide 101 and a second slide 102 located on one side of the first slide 101 close to the central axis of the baffle body 1. The first slide 101 can balance the situation where the initial imbalance is large, and the second slide 102 can balance the situation where the initial imbalance is small.

[0047] Specifically, when the initial imbalance during the dynamic balancing process is too large, the number of balancing sliders 2 and the number of gaskets 24 in the balancing sliders 2 can be increased to form a larger total weight; when the initial imbalance during the dynamic balancing process is very small, the balancing slider 2 can be moved to the second slide 102 for dynamic balancing, and the accuracy of the dynamic balancing can be further adjusted by increasing or decreasing the number of gaskets 24 in the balancing slider 2.

[0048] In this way, by providing two first slideways 101 to adjust the unbalance amount, the balance of the rotor can have a higher adjustment accuracy, and the addition and movement operations of the balancing slider 2 can be performed quickly and accurately.

[0049] Preferably, there are multiple installation channels 12, which are spaced apart around the central axis of the baffle body 1, and the extension direction of each installation channel 12 is parallel to the radial direction of the baffle body 1, and the angle between the extension directions of two adjacent installation channels 12 is an obtuse angle or an acute angle.

[0050] In this way, the balancing slider 2 can be installed more quickly, thereby improving the working efficiency of dynamic balancing.

[0051] like Figures 1 to 4 As shown, the groove body 111 has a groove bottom surface 113 and a groove top surface 114 on opposite sides, and both ends of the opening portion 112 are respectively connected to the groove top surface 114 and the end surface of the baffle body 1 close to the groove top surface 114.

[0052] like Figures 1 to 4 As shown, a groove 13 is provided on the groove bottom surface 113 , and the inner wall surface of the groove 13 is clearance-matched with the outer peripheral surface of the base 22 , so that the base 22 can be movably arranged relative to the groove 13 .

[0053] Preferably, there are multiple grooves 13 , and the multiple grooves 13 are arranged at intervals around the central axis of the baffle body 1 ; wherein the grooves 13 are cylindrical hollow bodies and the grooves 13 are blind holes.

[0054] Specifically, each slideway 11 is provided with a plurality of grooves 13, and the number of the grooves 13 can be adjusted according to the size of the baffle body 1 and the base 22. When the base 22 of the balancing slider 2 is inserted into the groove 13 of the slideway 11, the groove 13 can limit the tangential movement and radial movement of the balancing slider 2 (the tangential and radial directions are respectively Figure 2A and B directions in the diagram).

[0055] like Figure 3 As shown, when the rotor rotates, the centrifugal force exerted on the balancing slider 2 causes it to have a tendency to deviate from the central axis of the baffle body 1. Since there is a large friction between the gasket 24 and the groove top surface 114 of the slideway 11 of the baffle body 1 and the base 22 is pressed into the groove 13 by the pressure of the elastic member 23, the tangential movement of the balancing slider 2 is limited, so that the balancing slider 2 will not deviate from the unbalanced position in the slideway 11, and can be used even in motors with higher speeds, thereby expanding the use range of the rotor baffle.

[0056] like Figure 4 As shown, the adjustment process of the balancing slider 2 is: first, pull the pull rod 21 of the balancing slider 2 in the away direction to drive the base 22 to separate from the groove 13, then pull the pull rod 21 to move along the extension trajectory of the slide 11, so that the balancing slider 2 moves to an unbalanced position in the slide 11, and finally release the pull rod 21 so that the base 22 is pressed into the corresponding groove 13 by the elastic member 23.

[0057] Preferably, the baffle body 1 is an integrally formed casting; and / or the inner wall surface of the baffle body 1 is interference fit with the outer circumferential surface of the rotor shaft 100; and / or an insertion protrusion 14 is provided on the inner wall surface of the baffle body 1, and an insertion groove for plugging with the insertion protrusion 14 is provided on the outer circumferential surface of the rotor shaft 100.

[0058] The baffle body 1 of the rotor baffle of the utility model is an integrally formed casting, which solves the problems that the rotor baffle of the motor in the prior art is manufactured by machining, which has many processing steps, high processing costs and complicated rotor assembly process.

[0059] The inner wall surface of the baffle body 1 of the rotor baffle of the utility model is interference-fitted with the outer peripheral surface of the rotor shaft 100 and is installed by shrink-fitting. The baffle body 1 generates a large friction force with the rotor shaft 100 by relying on the interference, thereby limiting the axial movement of the baffle body 1 and the rotor core 200, and there is no need to use a locking nut or a welding ring for axial limiting, so that the structure of the rotor is simpler, and the required processing time and production cost are also lower.

[0060] like Figure 6 As shown, the utility model provides a rotor, including: a rotor shaft 100; a rotor core 200, the rotor core 200 is sleeved on the rotor shaft 100; the above-mentioned rotor baffle 300, the rotor baffle 300 is sleeved on the rotor shaft 100 and is located on one side of the rotor core 200.

[0061] The utility model also provides a motor, comprising the above-mentioned rotor.

[0062] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

The width of the part 112; the balancing slider 2, the balancing slider 2 includes a pull rod 21 and a base 22, an elastic member 23 and a gasket 24 located in the slide 11, the elastic member 23 and the gasket 24 are sequentially sleeved on the pull rod 21, the base 22 is located on the side of the elastic member 23 away from the opening 112, one end of the pull rod 21 is fixedly connected to the base 22, and the other end of the pull rod 21 extends out of the baffle body 1 through the opening 112; wherein the balancing slider 2 is movably arranged relative to the slide 11. In this way, the rotor baffle of the utility model is provided with the slideway 11 and the balancing slider 2, and the balancing slider 2 can be quickly moved to any unbalanced position on the slideway 11 by only pulling the pull rod 21 to make the base 22 compress the elastic member 23, so as to achieve the purpose of dynamic balancing of the rotor, realizing a new dynamic balancing method, solving the problem that the rotor baffle in the motor in the prior art needs to be provided with a welding ring or a round nut for axial limiting, resulting in more production processes and higher costs for the rotor, solving the problem that the rotor baffle in the motor in the prior art has a threaded hole and uses a copper screw counterweight and has a high dynamic balancing cost, solving the problem that the prior art The invention relates to a motor having a rotor baffle which is provided with a plurality of balancing pastes and a plurality of balancing pastes, and a plurality of balancing pastes are provided for the motor, and the balancing work is repeated because the amount of balancing paste and the pasting position are uncontrollable during dynamic balancing.

The problem that the dynamic balancing paste in the prior art is not able to be used in high-speed motors and there is a risk of falling off is solved, thereby solving the problem that the dynamic balancing cost of the rotor baffle of the motor in the prior art is high, improving the work efficiency of dynamic balancing, and solving the problem that the rotor baffle of the motor in the prior art requires a lower speed during dynamic balancing, thereby expanding the application of balancing paste in high-speed motors.
