Abstract

The utility model relates to a raster encoder code wheel; the code wheel body is made of SUS 304 stainless steel; a positioning hole (1) and a raster (2) formed by two circles of rectangle holes are machined on the code wheel body; the rectangle holes are arranged annularly taking the circular center of the code wheel body as center; wherein, the outer circle raster is composed of 370-400 rectangle holes and the inner circle raster is composed of 130-150 rectangle holes. The raster encoder code wheel has simple structure principle, uses good material and realizes the average service life of tens of thousands of hours, has strong anti-interference performance and high stability.

Description

The grating encoder code-disc
Technical field
The utility model belongs to the grating encoder field, particularly relates to a kind of grating encoder code-disc.
Background technology
Photoelectric encoder is a kind of sensor that the geometry of machinery displacement on the output shaft is converted to pulse or digital quantity by opto-electronic conversion.This is to use maximum sensors at present, and photoelectric encoder is made up of grating dish and photoelectric detection system.The grating dish is to open several slots on the plectane of certain diameter five equilibrium.Because photoelectric code disk is coaxial with motor, during the motor rotation, grating dish and motor are with the speed rotation, the pick-up unit of forming through electronic components such as light emitting diodes detects the some pulse signals of output, the rotating speed that just can reflect current motor by the number of calculating per second photoelectric encoder output pulse, but because the rotating speed height is easy to damage, serviceable life is short when being to use.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of grating encoder code-disc, to solve the defective that lack serviceable life in the prior art.
A kind of grating encoder code-disc, disk body is made by the SUS304 stainless steel, have the grating (2) that pilot hole (1) and two circles are formed by slot on the disk body, rectangle is the center annular array with the center of circle of disk body, wherein the outer ring grating is made of 370~400 slots, and the inner ring grating is made of 130~150 slots.
Described outer ring grating is made of 389 slots, and the inner ring grating is made of 139 slots.
Beneficial effect
The utility model principles of construction is simple, and practical after the excellent material, mechanical mean lifetime can be more than several ten thousand hours, and antijamming capability is strong, the reliability height.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of grating encoder code-disc, disk body is made by the SUS304 stainless steel, thickness: 0.05mm, the corrosion precision is ± 1/30T surface planarity:<0.1mm; Have the grating 2 that pilot hole 1 and two circles are formed by slot on the disk body, rectangle is the center annular array with the center of circle of disk body, and wherein the outer ring grating is made of 389 slots, and the inner ring grating is made of 139 slots.

Claims (2)
