Embodiment
The utility model embodiment discloses a kind of bascule of rotor, provides larger balance mass with realization, and reduces the purpose of bascule own wt, the invention also discloses a kind of motor.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The bascule that the utility model embodiment discloses a kind of rotor comprises balancing frame 1 and balance weight 2, please refer to Fig. 2.Balancing frame 1 comprises wheel hub 10 and spoke 11 two parts, wherein, is provided with the axis hole that links to each other for rotating shaft on the wheel hub 10, and the spoke 11 that is arranged on the wheel hub 10 has many, and is on the radial plane that evenly is arranged on perpendicular to balancing frame 1 axis; Balance weight 2 can be arranged on the spoke 11.
When the bascule that uses present embodiment to provide is adjusted the center of gravity of rotor, determine first the size and location of rotor unbalance quality by experiment of dynamic balancing, according to experimental result, between corresponding adjacent spoke balance weight is being installed on the bascule that present embodiment provides, balance block size, thickness, quality are by the equilibrium radius of present embodiment and need the size of the amount of unbalance of balance to determine.Then continue to do experiment of dynamic balancing, can finely tune the quality of mounted balance weight according to experimental result, until residual unbalance, satisfies in the scope of design.
In the bascule that present embodiment provides, balance weight is arranged on the spoke of stabilizer, and therefore, size that can be by changing balance weight 2 and profile to be changing its quality, and then make bascule that larger balance mass can be provided.Simultaneously, balancing frame 1 comprises wheel hub 10 and the spoke 11 that links to each other with wheel hub 10, it is openwork part between the adjacent spokes 11, compare with the balancing frame of rosette profile in the existing bascule, when the two overall dimension is identical, the balancing frame quality that provides in the present embodiment is less, thereby the load that has alleviated machine shaft has prolonged its useful life.
Further, in the bascule that present embodiment provides, balance weight 2 comprises the first balance weight 20 and the second balance weight 21.Wherein the first balance weight 20 can be arranged on the spoke 11, and the second balance weight 21 both can be arranged on the spoke 11, also can be arranged on the first balance weight 20.By balance weight 2 being divided into the first balance weight 20 and the second balance weight 21, the user can not carry out under the prerequisite of manual setting the quality of balance weight 2, obtains required balance mass by flexible collocation the first balance weight 21 and the second balance weight 20.
When the bascule that uses present embodiment to provide is adjusted the center of gravity of rotor, determine unbalance mass, and position by experiment of dynamic balancing first, according to experimental result, the first balance weight 20 is being installed between corresponding adjacent spoke on the bascule that present embodiment provides.The first balance block size, thickness, quality are by the equilibrium radius of present embodiment and need the amount of unbalance of balance to determine.Then continue to do experiment of dynamic balancing, can the second balance weight that the polylith quality does not wait be installed at mounted the first balance weight 20 according to experimental result, with the fine setting residual unbalance,, until residual unbalance, satisfies in the scope of design.
For the position of centre of gravity to rotor is adjusted accurately, the user is when the bascule regulating rotary quantum balancing that utilizes above-described embodiment to provide, can suitably process balance weight 2, thereby increase or reduce the quality of balance weight 2, thereby utilize the adjusting of the balance weight realization rotor balancing of minimum number.
Provide in the bascule at above-described embodiment, between spoke 11 and the balance weight 2, can adopt welding, riveted joint or adopt securing member to link to each other between the first balance weight 20 and the second balance weight 21, preferably, be provided with screwed hole at spoke 11 and balance weight 2, all adopt securing member removably to be fixedly linked between spoke 11 and the balance weight 2 and between the first balance weight 20 and the second balance weight 21.
Preferably, the first balance weight 20 in above-described embodiment is the balance weight of arc, and the angle of adjacent two spokes equates on the central angle of its arc size and the balancing frame.By the first balance weight 20 is set to arc, can on the first balance weight 20, screwed hole evenly be set the central angle along arc, the user can take the screwed hole of even setting as reference, judge the installation site of the second balance weight 21, thereby simplify the using method of bascule.
Concrete, in the bascule that above-described embodiment provides, be provided with altogether six spokes 11 on the balancing frame 2, as shown in Figure 3, six spokes 11 be radial evenly be arranged on wheel hub 10 around.What can expect is, the quantity of spoke is fewer on the balancing frame, and the width of spoke is less, and the quality of balancing frame is less, also just more is conducive to alleviate the load that balancing frame brings to rotating shaft; But the quantity of minimizing spoke has increased the difficulty when utilizing balancing frame regulating rotary quantum balancing simultaneously, so the quantity of spoke can not be very few.Through the practical operation checking, the balancing frame that is provided with six spokes can satisfy the demand of utilizing bascule to adjust rotor balancing.
Simultaneously, those skilled in the art can arrange the quantity of spoke according to the actual needs flexibly, as seven, eight or more spoke are set at balancing frame.
In the bascule that above-described embodiment provides, only be provided with screwed hole in the end of spoke 11, balance weight 2 can only be arranged on the end of spoke 11.Further, in the bascule that present embodiment provides, on spoke 11, also be provided with many group screwed holes.As shown in Figure 4, organize screwed hole along the length direction setting of spoke 11, the needs that the user can be actual are installed the balance weight 2 of suitable weight in suitable place more, thereby realize the balance of rotor with the bascule gross mass of minimum.
The utility model also provides a kind of motor, is provided with above-mentioned bascule in this motor, has realized alleviating the purpose of motor weight.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
