Root A.When balance weight 200 rotates to tend to transverse shifting, stop plane 252 is against side plane 152 and backstop cambered surface
254 against side cambered surface 154, to (further) transverse shifting of limiting balance block 200 relative to rotor 100.
Preferably, side, that is, side plane 152 of recess portion 150 and side cambered surface 154 can be arranged to mounting post 110 in transverse direction
A distance is spaced apart on direction to form step between side plane 152 and side cambered surface 154 and the peripheral surface of mounting post 110
Thus portion further enhances the structural strength at the root A of mounting post 110.
Fig. 6 shows the force analysis of each section of rotor 100 and balance weight 200.As shown in fig. 6, when balance weight 200 by
When rotation is intended to the transverse shifting (along right direction shown in fig. 6), the stop plane 252 and backstop cambered surface of protrusion 250
254 can bear against the side plane 152 and side cambered surface 154 of recess portion 150, to apply cross to the right to the ontology 120 of rotor 100
To power F2；Correspondingly, side plane 152 and side cambered surface 154 apply cross force F2 ' to the left to the protrusion 250 of balance weight 200.Together
Sample, mounting portion 210 applies cross force F1 to the right to mounting post 110, and mounting post 110 applies to the left to mounting portion 210
Cross force F1 '.Cross force F1 and F2 and cross force F1 ' and F2 ' respective active force and reaction force each other.Cross force F1 ' and F2 '
The centrifugal force F suffered by balance weight 200 can be offset in a lateral direction, so that balance weight 200 (in a lateral direction) is dynamic
State balances.Thus, each power described above should meet following equation 1-3：
F1=F1 ' ... ... ... ... equatioies 1
F2=F2 ' ... ... ... ... equatioies 2
F1 '+F2 '=F ... ... ... equatioies 3
According to content described above and with reference to Fig. 6 it is found that protrusion 250 will be former by applying cross force F2 to ontology 120
The cross force F (=F1+F2) that mounting post 110 should be acted on is decreased to cross force F1, occurs to break to reduce mounting post 110
The risk split.
Preferably, on horizontal direction (horizontal direction as shown in FIG. 6), protrusion 250 can be from the freedom of mounting portion 210
(left transverse end as shown in FIG. 6) (to the right) is held to extend, until making the stop plane 252 of protrusion 250 extend substantially to install
The middle position in hole 230 (see Fig. 4).This can enable the position of above-mentioned cross force F1 and F2 is substantially right in a lateral direction
Standard, to optimize stress configuration.
Preferably, for processing and installation the purpose of, side plane 152 and side cambered surface 154 and stop plane 252 and backstop
Cambered surface 254 can be arranged each parallel to rotation axis X.However, in the other embodiment of the application, side plane 152 and side
Cambered surface 154 and at least one of stop plane 252 and backstop cambered surface 254 can be relative to the angled settings of rotation axis X.
Specifically, as shown in fig. 7, stop plane 252 can be disposed relative to rotation axis X angled and towards balance
220 side of counterweight part of block 200 tilts.It is to be herein pointed out stop plane 252 relative to rotation axis X towards counterweight
220 side of portion tilts and refers to：Towards counterweight part 220, i.e., stop plane 252 is inclined to from the position for being parallel to rotation axis X
The normal vector of stop plane 252 is directed toward counterweight part 220.Correspondingly, side plane 152 can be disposed relative to rotation axis X at
Angle and towards rotor 100 for example its 120 side of ontology tilt, i.e., side plane 152 from be parallel to rotation axis X position tilt
At towards ontology 120, i.e. the normal vector of side plane 152 is directed toward ontology 120.When balance weight 200 is installed to rotor 100, backstop
Plane 252 can be against side plane 152 so that protrusion 250 (also in the axial direction) can be interlocked with recess portion 150.It is this mutual
Lock can reduce the axial tension applied by balance weight 200 that mounting post 110 is born, and (axial tension is along shown in fig. 7
Upward direction), it further reduced the risk that mounting post 110 is broken.In addition, according to the convex of this embodiment of the application
The interlocking of portion 250 and recess portion 150 can also be prevented in use when mounting post 110 fails completely or partially balance weight 200 with
Rotor 100 detaches.
In the other embodiment of the application, can stop plane 252 be only disposed relative to rotation axis X angulations
Degree, and corresponding side plane 152 is aligned parallel to rotation axis X.For example, since the material for constituting side plane 152 is opposite
Often there is smaller intensity in the material for constituting stop plane 252, thus even if side plane 152 is not configured to and stop plane
252 exactly match, and also side plane 152 can be forced to deform upon and realize two when stop plane 252 is engaged with side plane 152
Matching between person.
In addition, in other embodiments, side plane 152 and side cambered surface 154 and stop plane 252 and backstop cambered surface
The feature for increasing friction force, such as wave can be provided at least one of 254, to further prevent rotating
Middle balance weight 200 occurs (axial direction) with rotor 100 and detaches.
In the other embodiment of the application, alternatively or additionally, balance weight may include matching from balance weight
The protrusion that weight portion extends.Since counterweight part usually has the area of section than mounting portion bigger, thus increase the protrusion
Intensity.
It should be pointed out that in the preferred embodiment of the application, balance weight 200 can be integrally formed, for example, can be with
Balance weight 200 is integrally formed by casting and/or turnery processing.But in other embodiments, according to the protrusion of the application
250 can be fixed to the mounting portion 210 and/or counterweight part 220 of balance weight 200 by way of welding or fastener connection.
