Description

A kind of high frequency rotation power transformation pivot and its winding fixing means

Technical field

The present invention relates to a kind of high frequency rotation power transformation pivot and its winding fixing means.

Background technique

Rotary transformer is as position, the sensing element of revolving speed, it is desirable that precision and reliability with higher.In addition to tradition , except the military, aerospace field for requiring high reliablity, in recent years, also obtained in industry, traffic and civil field It is widely applied.In general, to become enameled wire line footpath used all very small for rotation, it is even more small that some reaches 0.1mm, processed in armature Easily cause enameled wire injured in journey or broken string, therefore, processing technology difficulty is very big.In addition, for distributed winding Rotation becomes stator armature, needs when offline across several slots, and enameled wire line footpath as used in it is small, thus can only hand insertion, end Portion's enameled wire is more open, needs to be fixed with special method.Conventional distributed-winding stator armature technical process is： Slot insulation is assigned into iron core slot first, then will be bound under enameled wire in iron core slot, then by end enameled wire line, Slot wedge is finally squeezed into iron core slot.The purpose for squeezing into slot wedge is that slot insulation is prevented to be higher by iron core inner hole, is interfered with rest part, It prevents enameled wire from deviating from from slot simultaneously, causes motor to sweep hall with rotor interference, using above-mentioned technical process, due to core material Softer, slot wedge may cause notch deformation, and be easy to cause iron core injured, cause its performance impacted, then since iron core is shorter, Slot wedge is easy to loosen and drop out, and the purpose of fixed coil is not achieved.

Summary of the invention

In order to solve the above technical problems, the present invention provides a kind of high frequency rotation power transformation pivot and its winding fixing means.

The present invention is achieved by the following technical programs.

A kind of high frequency rotation provided by the invention becomes armature winding, including winding and iron core；On the cup inner wall of the iron core It is even to be connected with several iron core teeths, tooth socket is machined between adjacent iron core teeth, the winding is embedded in each tooth socket, the winding It is tightened by binding wire and is fixed in iron core by binding wire.

The binding wire is cotton thread or bright and beautiful silk thread.

A kind of high frequency rotation change armature winding fixing means, is fixed, step is by binding wire：

1. being passed through on the inside of the adjacent winding of tooth socket using binding wire, along the A when front winding to spiral winding winding one week；

2. binding wire turn to the A to winding to reverse acting spiral wind winding one week；

It passes through 3. binding wire is drawn to after one circle of other side winding winding to changing the A of winding to winding with one circuit；

4. the A that traction binding wire turns to ipsilateral winding is wound winding one week to reverse acting spiral；

5. drawing on binding wire winding adjacent iron cores tooth far from when then winding one end in front side winds the another of adjacent iron cores tooth One end successively winds each iron core teeth on iron core；

6. binding wire continues forward to continue step 5. behind its continuous two side after winding the last one iron core teeth；

7. the end of traction is fixed after completing binding.

The step 1. -4. in spiral winding spiral spacing and two adjacent iron core teeths between with side spacing.

The step 7. in draught line is involved from the initial position of binding and is mutually bound with initial end after it is fixed.

The step 7. in the end of draught line and initial end are fixed on adjacent binding wire.

The beneficial effects of the present invention are：By the cabling mode of binding wire, can only be realized with single line by armature The winding of both ends winding and each iron core slot of iron core is fixed；Binding wire is mutually drawn on each fixed point, fixed effect More preferably；Binding wire on the tooth of iron core when winding, by slot insulation gear behind binding wire, it is therefore prevented that slot insulation is higher by iron core Hole, while slot insulation being made to push down the enameled wire in iron core slot.

Specific embodiment

Be described further below technical solution of the present invention, but claimed range be not limited to it is described.

A kind of high frequency rotation change armature winding, including winding 1 and iron core 2；If being uniformly connected on the cup inner wall of the iron core 2 Iron core teeth 21 is done, is machined with tooth socket 22 between adjacent iron core teeth 21, the winding 1 is embedded in each tooth socket 22, the winding 1 It is tightened by binding wire and is fixed in iron core 2 by binding wire.

The binding wire is cotton thread or bright and beautiful silk thread.

1. being passed through on the inside of the adjacent winding of tooth socket 22 using binding wire, along the A when front winding to spiral winding winding one week；

5. drawing on binding wire winding adjacent iron cores tooth 21 far from when then winding one end in front side winds adjacent iron cores tooth 21 The other end, successively wind iron core 2 on each iron core teeth 21；

6. binding wire continues forward to continue step 5. behind its continuous two side after winding the last one iron core teeth 21；

7. the end of traction is fixed after completing binding.

The step 1. -4. in spiral winding spiral spacing and two adjacent iron core teeths 21 between between side Away from.

As shown in Figure 2：

Fig. 2 is armature binding wire cabling schematic diagram after inner hole expansion, and winding 1 is the dotted portion in figure, and solid line is to tie up Binding；

Each serial number 3~10 indicates the position of binding wire in Fig. 2, and arrow direction indicates the direction of routing of binding wire；

Specific implementation step is：

(1) binding wire is initially entered from position 3, and in the direction of the arrow to diagram right-hand direction coiling, winding is fixed；

(2) after around a circle, in-position 4 starts reversely, starts coiling to diagram left hand direction in the direction of the arrow, around Cross one circle after in-position 5；

(3) behind in-position 5, the other end of armature is entered along the slot of iron core 2, in the direction of the arrow to diagram right hand side To coiling, around complete in-position 6 after a week；

(4) start reversed behind in-position 6, start coiling to diagram left hand direction in the direction of the arrow, around it is complete after a week, arrive Up to position 7；

(5) behind in-position 7, link position 8 enters iron core slot in the direction of the arrow, is successively wound on iron core in the direction of the arrow On each tooth, start in the direction of the arrow reversely in position 9 after a week around complete；

(6) after position 9 is reversed, each tooth of iron core 2 is bypassed in the direction of the arrow, is finally drawn and is consolidated from position 10 It is fixed.
