Abstract
The utility model relates to a photoelectric speed-measuring code wheel, which comprises a boss and a code wheel sheathed on a rotary shaft, wherein, the code wheel is a circular ring, and is sheathed on the rotary shaft; the inner edge of the circular wall of the code wheel is fixed at the rear part of the boss, and the shaft cores are mutually overlapped; the circumference of the outer edge of the circular wall of the code wheel is circularly printed with uniform raster-shaped stripes having certain width and chromatism contrast. The utility model has the advantages of no need of complicated gullet processsing procedure, the reduction of speed-measuring device processing cost, metal material saving, and light weight.
Description
The utility model relates to a kind of device of measuring the rotating shaft rotating speed, especially a kind of by optoelectronic induction, produce the novel code-disc that tests the speed easy, with low cost.
At present, in industrial automatic control, especially motor drags control, generally all needs to measure the rotating speed of rotating shaft in operational process, so that can access the rotating shaft real-time status, and this status signal is fed back to control device, and form closed-loop control.Existing speed measuring device is a sheathed boss in rotating shaft, and a disk is extended in outer ring, boss rear portion, and the periphery of disk utilizes milling cutter to mill out many teeth groove, and is in service in rotating shaft, utilizes electrooptical device to read the number of teeth groove, obtains corresponding revolution.When needs provide measuring accuracy, must increase the number of teeth groove, on circumference, increase the teeth groove number, need utilize fine-processing technique just can mill out more thinner teeth groove, complex process, difficulty of processing is big.Because the disk overall volume of boss and extension thereof is big, need mould also just big in addition, waste of material is also big, and production cost significantly rises.
The purpose of this utility model is to provide a kind of luminous point code-disc that tests the speed, and it does not use the teeth groove code-disc, whole speed measuring device manufacture easily and cost lower.
The purpose of this utility model is achieved in that a kind of photoelectric velocity measurement code-disc, it comprises boss and the code-disc that is set in the rotating shaft, wherein said code-disc is an annulus, be set in the rotating shaft vertically, the edge is fixed in the boss rear portion in the code-disc ring wall, the axle center is overlapped, and code-disc ring wall outer Zhou Bianhuan is printed on the uniform grating shape striped of certain width and aberration contrast.
Described code-disc can be film or the paper of certain degree of hardness is arranged.
Described film can be sticked and constitute code-disc jointly on a hard material.
Described code-disc can fix or adhere to or be screwed on the boss.
The utility model not only no longer needs complicated teeth groove machining process, greatly reduces the production cost of speed measuring device, and has saved metal material, has alleviated weight.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural profile synoptic diagram;
Fig. 2 faces structural representation for the utility model code-disc.
Referring to Fig. 1,2, a kind of photoelectric velocity measurement code-disc, it comprises boss 2 and the code-disc 3 that is set in the rotating shaft 1, and wherein code-disc 3 is two independently parts with boss 2, and boss 2 only plays the effect of supporting the location, and code-disc 3 is used for reading.Code-disc 3 of the present utility model is an annulus, is set in vertically in the rotating shaft 1, and the edge is fixed in boss rear portion, code-disc 3, rotating shaft 1, overlapped location, boss 2 axle center in code-disc 3 ring walls.Code-disc 3 ring wall outer circumferential annular are printed with the uniform grating shape striped 4 of certain width and aberration contrast.The material of code-disc 3 can be film or certain thickness paper is arranged.Uniform grating shape striped can once print by 4 usefulness laser printers, and manufacturing is the simplest like this, and cost is also cheap, almost can't mention in the same breath with the cost of prior art.In addition, for improving the hardness of code-disc 3, the good film plaster of system striped can be located on the hard material 5 (for example organic glass), constitute code-disc 3 jointly, satisfy different needs in some occasions.Code-disc 3 fixes or adheres to or be screwed together with boss 2.During engaging, can be at boss 2 conduit of getting on the bus out, code-disc 3 directly snapped in get final product; Be screwed together, can screw on screw on the code-disc 3 and the boss 2 is involutory, insert bolt.
Claims (4)
1, a kind of photoelectric velocity measurement code-disc, it comprises boss and the code-disc that is set in the rotating shaft, it is characterized in that: described code-disc is an annulus, be set in the rotating shaft vertically, the edge is fixed in the boss rear portion in the code-disc ring wall, the axle center is overlapped, and code-disc ring wall outer Zhou Bianhuan is printed on the uniform grating shape striped of certain width and aberration contrast.
2, photoelectric velocity measurement code-disc according to claim 1 is characterized in that: described code-disc can be film or the paper of certain degree of hardness is arranged.
3, photoelectric velocity measurement code-disc according to claim 1 is characterized in that: described film can be sticked and constitute code-disc jointly on a hard material.
