Abstract
The utility model provides a kind of motor rotor balance weight, it is characterized in that, described balance weight is provided with two installing holes, and one of them installing hole is fixed installation hole, and another installing hole is adjustable installing hole.The utility model additionally provides a kind of motor comprising above-mentioned rotor balance.By this new structure, one of them installing hole is arranged to adjustable, the installation of balance weight can change within the specific limits across footpath; And keep another one installing hole fixedly to ensure to install reliably, so namely can not change original balance mode fork and facilitate the installation of balance weight and the management of stock.
Description
Technical field
The utility model relates to a kind of motor rotor balance weight, and a kind of motor with rotor balance.
Background technology
Motor, as the power source of electrical equipment or various machinery, is widely used in electric power and engineering goods field.In order to offset the amount of unbalance that rotor produces in the fabrication process, the mode of usually installing rotor balance is at present offset.Usually, balance weight is arranged on balancing frame by two circular holes.Because the quantity in the balancing hole radius on balancing frame and hole can change along with design, so different balancing frames just has different installations across footpath, so just needs to design new balance weight.Like this, the quantity of balance weight will certainly be increased, increase the difficulty of management.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, provides a kind of motor rotor balance weight, it is characterized in that, one of them installing hole is fixed installation hole, and another installing hole is adjustable installing hole.
In one embodiment, described fixed installation hole is circular, and described adjustable installing hole is strip.
In one embodiment, to be selected from the rectangular and linear pattern of circular arc rectangular for described strip.
In one embodiment, the shape of described balance weight is fan-shaped, quadrangle or U-shaped.
The utility model additionally provides a kind of motor, it is characterized in that, comprises the rotor balance as described in aforementioned any one.
By the structure of this new balance weight, one of them installing hole is made into the adjustable orifice of such as elongate holes, the installation of balance weight can change within the specific limits across footpath; And keep another one installing hole fixedly to ensure to install reliably.Because installation dimension is adjustable, not only this balance weight just can be used in different equilibrium radius, the different balancing frame installed across footpath, can not change original balance mode but also facilitate the installation of balance weight and the management of stock.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the rotor balance of a kind of execution mode of the utility model; And
Fig. 2 shows the assembling schematic diagram of the rotor balance of a kind of execution mode of the utility model.
Embodiment
Below with reference to accompanying drawing, give the specific descriptions of Alternate embodiments of the present utility model.
In general, motor includes the parts such as stator, rotor, support.These structures that motor of the present utility model can adopt this area conventional, are therefore not described further, and only describe the structure of rotor balance.
As shown in Figure 1, according to rotor balance of the present utility model, one of them installing hole has been designed to the hole of strip, keeps another one circular hole constant.Be to be understood that, the hole of this strip is not limited to the shape shown in Fig. 1, and should be understood to comprise various elongate in shape and other shapes, such as, this strip can be that circular arc is as shown in the figure rectangular, and can also be that linear pattern is rectangular, it both can along the circular arc being the center of circle with balancing frame center, its installation this circular arc can also be departed from, as long as can meet the purpose of this utility model.For the ease of understanding, they are referred to as " adjustable installing hole ".
As shown in Figure 2, balance weight 20 is arranged on balancing frame 30 scheme of installation.By the structure of this new balance weight, one of them installing hole is made into elongate holes, can change between scope S1 to S2 across footpath originally; And keep constant guarantee of another one installation circular hole to install reliably.Because installation dimension is adjustable, not only this balance weight just can be used in different equilibrium radius R, the different balancing frame installed across footpath, can not change original balance mode but also facilitate the installation of balance weight and the management of stock.
Although of course it is to be understood that aforementioned in mention maintenance installing hole be circular port, its objective is in order to the position of safe stable equilibrium block is to ensure reliable installation.Therefore, other similar modification are all in scope of the present utility model, and such as size can hold triangle or the quadrangle of the large stove bolt of equivalent diameter just, all in scope of the present utility model.For the ease of understanding, they are referred to as " fixed installation hole ".In addition, the shape that should be appreciated that balance weight is not by the restriction shown in figure, and it can adopt various shape, includes but not limited to fan-shaped, quadrangle or U-shaped etc.
Above-described is only principle of the present utility model and preferred embodiment, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
