Abstract
A kind of AC induction motor coding disk, comprise coding disk main body, the center of described coding disk main body is provided with the installing hole be connected with machine shaft, it is characterized in that: described coding disk main body adopts the one-time formed plate-like ferrule arrangement of sheet metal punching press, form multiple long slot bore in the outer circumference surface side of coding disk main body, form the installing hole of a flange at the center of coding disk main body.Product is by sheet metal punching press one-shot forming, makes structure more reasonable, not only energy-conservation but also environmental protection, decreases labour cost; In addition owing to adopting sheet metal to replace original cast steel or round steel, material cost is made to reduce more than 70%, and handling ease, good product consistency, applicable production in enormous quantities; The present invention is simple and reasonable, the cost of material is low, lightweight and handling ease, also can reduce rotor inertia operationally and noise simultaneously, effectively improves the performance of motor.
Description
Technical field
The present invention relates to machine field, particularly relate to a kind of AC induction motor coding disk by the outside output pulse signal of external encoder.
Background technology
AC induction motor, as a kind of new technology, the industrial vehicle such as electrocar and electri forklift of modern logistics industry is widely applied, is just playing great function.
Along with the continuous progress of motor speed control technology, electric industry vehicle is from rheostatic speed regulation control the earliest, direct current series-excited motor speeds control, direct current separately excited machine speeds control to AC induction motor speeds control future development.
The advantage that AC induction motor is given prominence to the most does not have carbon brush, its feature: efficiency is high, volume is little, lightweight, structure is simple, non-maintaining, good heat dissipation, degree of protection are high and long service life.But in order to the rotating speed that controls AC induction motor with turn to, when needing motor to rotate, export the pulse signal that two phase differences are 90 degree.Current majority adopts the method for external encoder, and as shown in Figure 4, this method needs to install a coding disk on machine shaft, and motor housing installs an encoder, and when motor rotates, encoder is with regard to the pulse signal needed for exporting.
At present, AC induction motor coding disk (as shown in Figure 3) all adopts cast steel or round steel to carry out cutting, Gear Milling, and manufacturing procedure complexity, long processing time, material cost and labour cost are high, is not suitable for producing in enormous quantities.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple and reasonable, the AC induction motor coding disk that the cost of material is low, process velocity is fast, steel sheet material is adopted to replace original cast steel or round steel, not only the cost of material is low, simultaneously handling ease, good product consistency.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of AC induction motor coding disk, it comprises coding disk main body, the center of described coding disk main body is provided with the installing hole be connected with machine shaft, it is characterized in that: described coding disk main body adopts the one-time formed plate-like ferrule arrangement of steel plate punched, be distributed with multiple long slot bore in the outer circumference surface side of coding disk main body, form the installing hole of a flange at the center of coding disk main body.
As improvement, the one end open of described coding disk main body, the other end to center, inwardly in step-like turnover, form the groove of an annular between installing hole and the turnover face of coding disk main body
Improve again, the outer circumference surface of described coding disk main body evenly offers multiple long slot bore, the plane being perpendicular of described long slot bore and described coding disk main body, and be connected with the turnover face of described coding disk main body.
Finally, the length of described long slot bore is 80% ~ 90% of the outer circumference surface width of described coding disk main body, and the quantity of long slot bore needs according to motor and determines.
Compared with prior art, the invention has the advantages that: product forms by steel plate punched is shaping, make structure more reasonable, not only energy-conservation but also environmental protection, decrease labour cost; In addition owing to adopting steel plate to replace original cast steel or round steel, material cost is made to reduce more than 70%, and handling ease, good product consistency, applicable production in enormous quantities; The present invention is simple and reasonable, the cost of material is low, lightweight and handling ease, also can reduce rotor inertia operationally and noise simultaneously, effectively improves the performance of motor.

Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in the figure, a kind of AC induction motor coding disk, on the machine shaft being arranged on AC induction motor 2 on 3, coordinates with the external encoder 4 be arranged on motor 2 shell, when motor 2 rotates encoder 5 just can export needed for pulse signal; Described AC induction motor coding disk, comprises coding disk main body 1, and described coding disk main body 1 adopts the one-time formed ferrule arrangement in plate-like of sheet metal punching press, forms the installing hole 11 of a flange, be connected with machine shaft 3 at the center of coding disk main body 1; The one end open of described coding disk main body 1, the other end to center, inwardly in step-like turnover, form the groove 13 of an annular between installing hole 11 and the turnover face of coding disk main body 1; The outer circumference surface of described coding disk main body 1 evenly offers multiple long slot bore 12 near side, turnover face, the length of described long slot bore 12 is 80% ~ 90% of the outer circumference surface width of described coding disk main body 1, the plane being perpendicular of described long slot bore 12 and described coding disk main body 1, and be connected with the turnover face of described coding disk main body 1; The quantity of long slot bore 12 needs according to motor 1 and determines.
Described coding disk, when adopting sheet metal to produce, first by stamping die punching blanking, then passes through shaping mould punch forming.
The present invention adopts steel sheet material punch forming to replace original cast steel or round steel, makes material cost to reduce by more than 70%, and handling ease, good product consistency, is applicable to producing in enormous quantities.Simultaneously due to lightweight, also can reduce rotor inertia operationally and noise, effectively improve the performance of motor.
