Abstract
The utility model discloses a kind of rotor trim ring with gimbal function, comprise trim ring body, described trim ring body side offers the balance weight mounting groove of annular, the cross section of this mounting groove is swallowtail-shaped structure, and symmetry offers breach on mounting groove, be provided with the balance weight of the swallowtail-shaped structure matched in described mounting groove, this balance weight is provided with tapped through hole, also push up through balance weight the bottom being pressed in mounting groove by screw and balance weight is fixed in mounting groove.Effectively can reduce the axial space of rotor, labor and material saving, enhances productivity, and reduce production cost, structure is simple, fitting operation is easy, efficiency is high, and balance weight is fixed solid and reliable, can the stability of equilibrium of effective guarantee trim ring when High Rotation Speed.
Description
Technical field
The utility model belongs to motor component technical field, particularly relates to a kind of rotor trim ring with gimbal function.
Background technology
At present, traditional electric rotating machine, special high-speed rotary motor, for the ease of realizing the active balance of rotor, ensureing the stability of High Rotation Speed rotor, often independent gimbal being set respectively in the both sides of rotor, though also meet requirement, achieve to rotor effectively steadily, but occupy the rotor axial useful space, cause motor volume larger, and when producing installation, very inconvenient, time-consuming, affect production efficiency.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of structure simple, easy for installation, efficiency is high, in the dynamically balanced situation of effective guarantee rotor, effectively reduces the rotor trim ring with gimbal function that roller axial space takies.
The technical scheme adopted for realizing the purpose of this utility model is: this rotor pressing ring comprises trim ring body, described trim ring body side offers the balance weight mounting groove of annular, the cross section of this mounting groove is swallowtail-shaped structure, and symmetry offers breach on mounting groove, the balance weight of the swallowtail-shaped structure matched is provided with in described mounting groove, this balance weight is provided with tapped through hole, also pushes up through balance weight the bottom being pressed in mounting groove by screw and balance weight is fixed in mounting groove.
Some grooves or tapped blind hole is laid in described mounting groove.
Described balance weight is that two ends are swallowtail-shaped structure
Adopt rotor trim ring of the present utility model, there is following beneficial effect:
1) reduce the axial space hold of rotor, thus reduce motor volume, labor and material saving, reduce production cost;
2) simple installation, avoids traditional approach to need to install rotor pressing ring and gimbal respectively, can enhance productivity;
3) adopt mounting groove and the balance weight of swallowtail-shaped structure, and by screw, balance weight is fixed, can effectively avoid balance weight in high-band rotary course, be subjected to displacement the generation with slippage situation;
4) balance weight two ends all adopt swallowtail-shaped structure, easy for installation, and fast, no matter balance weight can be installed in mounting groove by which end easily hand-held.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the section structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment two;
Fig. 4 is the structural representation of balance weight in the utility model embodiment two.
Embodiment
Embodiment one
As shown in Figure 1 and Figure 2: a kind of rotor trim ring with gimbal function, comprise trim ring body 1, the side opening of described trim ring body 1 is provided with the balance weight mounting groove 2 of annular, the cross section of this mounting groove 2 is swallowtail-shaped structure, and symmetry offers breach 3 on mounting groove 2, the balance weight 4 of the swallowtail-shaped structure matched is provided with in described mounting groove 2, this balance weight 4 is provided with tapped through hole, also pushes up through balance weight 2 bottom being pressed in mounting groove 2 by screw 5 and balance weight 4 is fixed in mounting groove 2.
Embodiment two
As shown in Figure 3, Figure 4, the difference part of the present embodiment and embodiment one is: lay some grooves or tapped blind hole 7 in described mounting groove 2.Described balance weight 4 is swallowtail-shaped structure for two ends, and central shaft is to being provided with tapped through hole 6.
When balance weight 4 is installed, balance weight 4 is inserted in mounting groove 2 from the breach 3 of mounting groove 2 by parallel block, and slide onto correct position or suitable groove or tapped blind hole 7 place along mounting groove 2, be pressed in the bottom of mounting groove 2 or groove or tapped blind hole 7 by tightening screw 5.The utility model structure is simple, fitting operation is easy, efficiency is high, and balance weight is fixed solid and reliable, can the stability of equilibrium of effective guarantee trim ring when High Rotation Speed.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The technology contents of the not detailed description of the utility model is known technology.
