Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
A kind of balance mechanism for single-phase eddy current motor of the invention, as shown in Figure 1, include fixed plate 1, balance pipe 2,
Guide rod 3, balancing patch 4, balance weight 5 and locking piece 6, balance pipe 2 are vertically set in fixed plate 1, in fixed plate 1 with balance pipe
2 corresponding through-holes, balance pipe 2 are sleeved in the shaft of rotor, and fixed plate 1 is fixed with rotor.Guide rod 3 is inclined at
In fixed plate 1 and balance pipe 2；Balance weight 5 is slidably arranged on guide rod 3, and then position of the adjustment block 5 on guide rod 3
It sets, i.e. the distance of adjustment block 5 to rotor shaft.After adjusting, balance weight 5 and guide rod 3 are consolidated by locking piece 6
It is fixed.When being increased weight, balancing patch 4 is arranged in fixed plate 1, balance can be determined according to required increased weight
The quantity of piece 4.Balance pipe 2 is obliquely installed, and then it is upward to guarantee that either fixed plate 1 can be arranged in balancing patch 4.
In one embodiment, as shown in figure 3, guide rod 3 includes screw rod 31, i.e. one end of screw rod 31 is fixed at fixation
On plate 1, the other end is arranged on balance pipe 2, and then makes 31 slant setting of screw rod.Balance weight 5 is threadedly engaged with screw rod 31.It is first
First, screw rod 31 is threadedly engaged with balance weight 5, and the rotary motion of balance weight 5 is changed linear movement, is realized to balance weight 5
Micro axial movement；In addition, as shown in Figure 1-3, passing through the screw rod 31 being obliquely installed, according to the mutual pass on three side of right angled triangle
System, the angle between screw rod 31 and fixed plate 1 is α, i.e., adjacent side is cos α than bevel edge, according to formula, x=ycos α, wherein x is
The distance of 1 radiai adjustment of fixed plate, y are the distance that balance weight 5 is adjusted on screw rod 31；As it can be seen that by the way that screw rod to be obliquely installed,
Balance weight 5 is enabled to adjust more fine.
In one embodiment, as in Figure 3-5, screw hole 51 is set on balance weight 5, screw rod 31 is placed in screw hole 51, and
The screw thread of screw hole 51 is threadedly engaged with screw rod 31.Wherein, locking piece 6 can be nut, and nut is threadedly engaged with screw rod 31, when
After the position of balance weight 5 is adjusted, rotating screw cap, so that the both ends of nut compressing balance weight 5, and then 5 axis of limiting balance block
To movement.In a preferred embodiment, the first groove 32,51 inner wall extension axis of screw hole are axially set along it on the side wall of screw rod 31
To nonpenerative second groove 52 is arranged, the non-through end of the second groove 52 is close to the distal end of fixed plate 1.When balance weight 5 and silk
When bar 31 locks, the first groove 32 and the second groove 52 will lock its (the first groove 32 and the second groove 52 are open relatively)
Part 6 is placed in the first groove 32 and the second groove 52, is realized and is fixed to the first groove 32 and the second groove 52, prevents balance weight 5
Rotate and then change the relative position of balance weight 5 and screw rod 31.It will be appreciated that, due to rotor rotation when, centrifugation can be generated
Power, blocking of the locking piece 6 by 52 non-through end of the second groove, always in the first groove 32 and the second groove 52.Wherein,
Locking piece 6 and the first groove 32 and the second groove 52 are interference fitted, and overcome locking piece 6 by the frictional force of locking piece 6 and side wall
The gravity of itself, so that locking piece 6 will not leave the first groove 32 and the second groove 52 when static.
In another preferred embodiment, the attractable layer that setting can be attracted by magnet in the second groove 52 of balance weight 5, such as
Iron, cobalt, nickel；Locking piece 4 is magnet.It will be appreciated that, when locking piece is placed in the first groove 22 and the second groove 32, magnet with
Attractable layer is fixed, and prevents 4 free-falling of locking piece by magnet and attractable layer, and clump weight 3 and screw rod 21 is caused to unlock.Certainly,
Balance weight 5 can also be directly by that can be made by the material that magnet attracts, such as iron block.
In one embodiment, balance pipe 2 is by bearing holder (housing, cover) in the shaft of rotor.In electric motor starting, prevent from balancing
Pipe 2 shakes, and collides with shaft, causes the abrasion of shaft and balance pipe 2, and then influences to turn shaft balancing.
In one embodiment, as shown in fig. 6, several the first fixations are arranged in the circumferential direction that fixed plate 1 is provided with balance pipe 2
Hole 11.By the first fixation hole 11 by fixed plate 1 on rotor.And on the same circumference by the setting of the first fixation hole 11, it can
Change the direction that balance weight 5 balances by rotation fixed plate 1.
In one embodiment, as Figure 7-8,41 He of buttonhole is respectively set in the upper surface of balancing patch 4 and following corresponding position
Button point 42, and be that several buttonholes 41 are circumferentially arranged in the center of circle with balance pipe 2 in fixed plate 1, the button point 42 on balancing patch 4 and solid
41 position of buttonhole on fixed board 1 is corresponding.In addition, 42 matching of buttonhole 41 and button point on balancing patch 4.When seated, as long as will put down
The button point 42 of weighing apparatus piece is placed in the buttonhole 41 of fixed plate 1, and the button point 42 of balancing patch 4 is placed in the buttonhole 41 of another balancing patch 4.And
It is afterwards that balancing patch 4 and fixinig plate 1 is fixed, complete the installation to balancing patch 4.Preferably, buttonhole 41 and button point on every balancing patch 4
42 quantity is two or more.Stack balancing patch 4 to it.
In one embodiment, the second fixation hole 43 for installation is provided on balancing patch 4.Balancing patch 4 is solid by second
Determine hole 43 to be fixedly connected with fixed plate 1, can be fixed by rivet.Preferably, the second fixation hole 43 and first is fixed
11 position of hole is corresponding, after balancing patch 4 is mounted in fixed plate 1, rivet pass through the and fixation hole 43 and the first fixation hole 11 with
Rotor is fixed, and then fixed plate 1 and balancing patch 4 is fixed.
In one embodiment, guide rod 3 is at least arranged two, and is symmetrically arranged in fixed plate 1；It plays first solid
The balance of fixed board itself, secondly, being reinforced to fixed plate 1 and balance pipe 2.Preferably, guide rod 3 is arranged four or more, around
Balance pipe 2 is equal angular to be arranged in fixed plate 1.
In the use of the present invention, as shown in figures 1-8, increased balance required for being calculated according to dynamic balance test of rotor
The weight of block determines the quantity of balancing patch 4 according to the weight, and then balancing patch 4 is mounted in fixed plate 1, and selection pair
Fixed plate 1 is mounted on the rotor by the fixation hole 11 answered.Then take out locking piece 6, rotary balance block 5, the position of adjustment block 5
It sets, after the completion of adjusting, locking piece 6 is inserted into the first groove 32 and the second groove 52, and balance weight 5 is fixed.Then continue
Dynamic balancing measurement, if balance, adjusting is finished；If uneven, continue above-mentioned steps until adjustment.Wherein, it locks
The method for dismounting for determining part 6 is as follows, is inserted by pole from the first groove 32, withstands locking piece 6, pushes locking piece 6 to balance pipe 2
It pushes, locking piece 6 is made to leave the second groove 52, realize the unlock to guide rod 3 and balance weight 5.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
