Abstract
The invention discloses a speed-measuring reflecting device, which relates to the technical field of rotating shaft measuring mechanisms and comprises a rotating part, wherein at least one reflecting area and at least one non-reflecting area are arranged outside the rotating part along the circumferential direction. Through setting up reflection of light district and non-reflection of light district on same reflection of light strip product, ensure that reflection of light district and non-reflection of light district have unanimous size and interval, solved when pasting a plurality of reflection of light pieces because posting homogeneity, positional deviation etc. lead to the inaccurate problem of measuring result.
Description
Technical Field
The invention relates to the technical field of rotating shaft measuring mechanisms, in particular to a speed measuring and reflecting device.
Background
The existing method for providing the reflected light intensity difference is to paste a single reflector on a shaft, when the light intensity measured by a measuring device at the position of the reflector of the rotating shaft is different from that without the reflector, the light intensity is used as pulse distinction, and the rotating speed of the rotating shaft is measured by counting and analyzing the number of pulses and intervals.
The method is simple and easy to use, but the measurement precision is not high, only one reflector is generally pasted on one shaft, and when a plurality of reflectors are pasted, the measurement result is inaccurate due to pasting uniformity, position deviation and the like.
Disclosure of Invention
In order to solve the technical problems, the invention provides a speed measurement reflecting device which is used for improving the precision of rotating speed measurement and related analysis.
In order to achieve the purpose, the invention provides the following scheme:
the invention provides a speed measurement reflecting device which comprises a rotating part, wherein at least one reflecting area and at least one non-reflecting area are arranged outside the rotating part along the circumferential direction.
Optionally, a plurality of reflective areas and non-reflective areas are alternately arranged outside the rotating portion.
Optionally, the sizes of the plurality of light-reflecting areas are the same, and the sizes of the plurality of non-light-reflecting areas are the same.
Optionally, the reflective area and the non-reflective area are reflective parts and non-reflective parts on the reflective strip.
Optionally, the reflective strips are bonded or welded to the outside of the rotating portion.
Compared with the prior art, the invention has the following technical effects:
according to the speed-measuring reflecting device, the reflecting area and the non-reflecting area are arranged on the same reflecting strip product, so that the reflecting area and the non-reflecting area are ensured to have consistent size and interval, and the problem of inaccurate measuring results caused by pasting uniformity, position deviation and the like when a plurality of reflecting pieces are pasted is solved.

Description of reference numerals: 1. a light reflecting means; 2. a rotating shaft; 3. and a rotating speed measuring device.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 2, the present embodiment provides a speed measurement reflecting device, which includes a rotating portion, and eight reflecting areas and eight non-reflecting areas are arranged outside the rotating portion along a circumferential direction.
In this embodiment, the rotating portion includes a rotating shaft 2 driven by a power mechanism, the power mechanism may be a motor, and the rotating shaft 2 is in transmission connection with a driving shaft of the motor.
The reflection of light district and non-reflection of light district are reflection of light position and non-reflection of light position on the same reflection of light strip to guarantee that reflection of light district and non-reflection of light district have fixed size and proportion, make the reflection of light signal have better periodicity, and be convenient for direct use, solved because posting homogeneity, positional deviation etc. and lead to the inaccurate problem of measuring result.
When the rotating shaft 2 rotates, the reflecting device 1 is fixed in the circumferential direction of the rotating shaft 2, and when the rotating shaft 2 rotates, the reflecting area and the non-reflecting area of the reflecting device 1 alternately appear at the measuring point of the rotating speed measuring device. The rotation speed measuring device 3 can thereby obtain a plurality of light intensity variation pulses in one rotation cycle.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
