Abstract
The invention discloses a dynamic balancing structure for a permanent magnet synchronous motor rotor. The dynamic balancing structure comprises dynamic balancing nails and a rotor sheet. A plurality of dynamic balancing holes are formed in the two sides of the rotor sheet. The dynamic balancing nails are arranged in the dynamic balancing holes. A plurality of magnets are uniformly arranged on an outer ring of the rotor sheet. A rotating shaft penetrates through a center hole of the rotor sheet. The dynamic balancing holes are round through holes. The dynamic balancing nails of novel structures and the rotor sheet can be corrected in a dynamic balancing mode, and the exceeding unbalanced amount can be balanced easily, fast and effectively.
Description
Technical field
The present invention relates to electronics rotor technology field, be specifically related to a kind of permanent-magnetic synchronous motor rotor dynamic balance structure.
Background technology
In traditional motor, rotor increases the weight of dynamic balancing and uses dynamic balancing mud bar none, but uses dynamic balancing mud more loaded down with trivial details:
1. by good for 2 kinds of composition 1 to 1 proportionings, then mutually need mix to rub and crush up;
2. dynamic balancing mud itself is very hard when the temperature is low not easily mixes, and dynamic balancing mud need be dried to 40 ~ 50 DEG C in advance, preliminary drying time is 20 ~ 30 minutes;
3. during dynamic balancing, dynamic balancing machine shows quantitative interpolation dynamic balancing mud, but the quantitative dynamic balancing mud of each interpolation need claim to measure by miniature amount, very loaded down with trivial details.
Summary of the invention
Because the above-mentioned defect of prior art, the invention provides permanent-magnetic synchronous motor rotor dynamic balance structure, new construction dynamic balancing nail, the rotor punching of dynamic balance calibration can be carried out, thus balance the amount of unbalance exceeded standard simply, fast and effectively.
For achieving the above object, the invention provides permanent-magnetic synchronous motor rotor dynamic balance structure, comprise dynamic balancing nail and rotor punching, rotor punching both sides are provided with multiple dynamic balancing hole, dynamic balancing nail is provided with in described dynamic balancing hole, rotor punching outer ring is evenly provided with multiple magnet, is equipped with rotating shaft in rotor punching centre bore.
As preferably, described dynamic balancing hole is manhole.
As preferably, described dynamic balancing nail is for being opening elastic cylindrical pin.
As preferably, the dynamic balancing nail of described different size mates with the rotor of different model.
As preferably, the same position in the dynamic balancing hole of described rotor punching arranges multiple dynamic balancing nail.
Beneficial effect of the present invention: structure is simple, easy to use, can carry out new construction dynamic balancing nail, the rotor punching of dynamic balance calibration, thus balance the amount of unbalance exceeded standard simply, fast and effectively.
Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand object of the present invention, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the structural representation of rotor punching of the present invention;
Fig. 3 is the structural representation of dynamic balancing of the present invention nail.
Embodiment
With reference to Fig. 1-3, this embodiment is by the following technical solutions: permanent-magnetic synchronous motor rotor dynamic balance structure, comprise dynamic balancing nail 1 and rotor punching 2, rotor punching 2 both sides are provided with multiple dynamic balancing hole 3, dynamic balancing nail 1 is provided with in described dynamic balancing hole 3, rotor punching 2 outer ring is evenly provided with multiple magnet 4, is equipped with rotating shaft 5 in rotor punching 2 centre bore.
It should be noted that described dynamic balancing hole 3 is manhole.
It should be noted that described dynamic balancing nail 1 is for being opening elastic cylindrical pin.
It should be noted that the dynamic balancing nail 1 of described different size mates with the rotor of different model.
In addition, the same position in the dynamic balancing hole 3 of described rotor punching 2 arranges multiple dynamic balancing nail 1.
Designing rotor dynamic balancing of the present invention nail and rotor punching, first primary Calculation goes out the maximum amount of unbalance of rotor, then produces model machine rotor, and according to the multiple rotor of same specification, test of many times determination amount of unbalance exceeds standard numerical value, forms statistics; Adopt " weightening finish " method to carry out balance correction in consideration, determine that single quality is followed closely in counterweigh.
Embodiment 1: go out the maximum amount of unbalance of rotor according to primary Calculation
E=allows maximum amount of unbalance (μm)
K=constant 1000
G=accuracy class 2.5
ω=angular speed (π/60 ,=rotating speed × 2) (rad/s)
M=allows maximum amount of unbalance (g)
R=adds duplicate removal radius (mm)
M=workpiece quality (kg)
Going out the maximum amount of unbalance of rotor according to formulae discovery is 0.3g
The analysis of statistical data of same specification 10 rotors 20 times test, substantially also basic at about 0.9g at about 1g, the B end face amount of unbalance numerical value that exceeds standard at the A end face amount of unbalance numerical value that exceeds standard, therefore the quality of balanced nail is determined at about 1g.
Embodiment 2: go out the maximum amount of unbalance of rotor according to primary Calculation, goes out the maximum amount of unbalance of rotor according to primary Calculation
E=allows maximum amount of unbalance (μm)
K=constant 1000
G=accuracy class 2.5
ω=angular speed (π/60 ,=rotating speed × 2) (rad/s)
M=allows maximum amount of unbalance (g)
R=adds duplicate removal radius (mm)
M=workpiece quality (kg)
Going out the maximum amount of unbalance of rotor according to formulae discovery is 0.7g
The analysis of statistical data of same specification 10 rotors 20 times test, substantially also basic at about 1.6g at about 2g, the B end face amount of unbalance numerical value that exceeds standard at the A end face amount of unbalance numerical value that exceeds standard, therefore the quality of balanced nail is determined at about 2g.
By plurality of specifications rotor test, reach a conclusion and different size rotors all in our company need can be covered with 2 specification balanced nails, quality is 0.5g, 1g respectively.
According to the dynamic balancing nail specification of quality calculated, designing balanced nail shape size is: Φ 4.1x8mm, Φ 4.1x16mm, as Fig. 3.
According to dynamic balancing nail size, design rotor punching shape (as Fig. 2).
Rotor is uniformly distributed 32
manhole, wherein outer ring is 16 manholes, and be that the concentric circle of 23.5mm is uniformly distributed with radius R, inner ring is also 16 manholes, is that the concentric circle of 18.5mm is uniformly distributed with radius R, and rotor core length is 35mm.
A kind of new construction carrying out dynamic balance calibration provided by the present invention, its mentality of designing is also applicable to the structural design of the similar revolving parts of miscellaneous equipment, thus the amount of unbalance eliminated easily.
