Abstract
The utility model discloses a single-loop encoder, which comprises a top cover, a transmission shaft, and a pedestal sleeved on the transmission shaft, wherein the top cover and the pedestal are in fixed connection and form an encoder internal cavity. The single-loop encoder is characterized in that a magnetic steel pedestal is sleeved on one transmission shaft end positioned in the encoder internal cavity, the magnetic steel pedestal is provided with a magnetic steel, the magnetic steel is connected with the transmission shaft, a circuit board is arranged on the top wall of the encoder internal cavity, a magnetic inductor is arranged on the circuit board and relative to the magnetic steel, and the magnetic inductor and the magnetic steel are in interval arrangement. The single-loop encoder has long service lifetime and high measuring precision.
Description
Technical field
The utility model relates to a kind of scrambler, relates in particular to a kind of single-ring encoder, specifically is applicable to the measurement to the mechanical rotation angular displacement.
Background technology
At present, in modern electro-mechanical system, usually need to use scrambler that mechanical motion is measured, quantized after, thereby finish accurate control to mechanism system.
The Chinese patent Granted publication number is CN2731403Y, and Granted publication day is that the utility model patent on October 5th, 2005 discloses a kind of scrambler, includes a pedestal, and this base bottom surface is provided with the metallic brush plate that is loop shaped; One folding moving plate, it is arranged on the pedestal; This folding moving plate is provided with and is equally spaced conducting strip, and this conducting strip is just conflicted on the metallic brush plate; One rotating disk, it is to be set on the folding moving plate, the face of this turntable surface doubling moving plate is provided with the first bayonet socket spare; One pressure part, it is to be pressed against on the rotating disk, this pressure part one end just is set on the pedestal, and this pressure part is provided with a ring frame; One housing is coated togather pedestal, folding moving plate, rotating disk and pressure part.Though but this utility model reduce wear not only increases life of components, and can also increase the convenience of assembling.But because the employed brush plate of this utility model is easy to wear, serviceable life is shorter, and in addition, brush plate causes the measuring accuracy of scrambler lower after wearing and tearing.
Summary of the invention
The objective of the invention is to overcome defective and the problem that serviceable life is short, measuring accuracy is lower that exist in the prior art, provide a kind of serviceable life long, the higher single-ring encoder of measuring accuracy.
For realizing above purpose, the technology used in the present invention solution is: a kind of single-ring encoder, comprise top cover, transmission shaft and be set in base on the described transmission shaft, after fixedlying connected with described base, described top cover forms the scrambler inner chamber, it is characterized in that: the end that described transmission shaft is positioned at described scrambler inner chamber is arranged with the magnet steel base, described magnet steel base is provided with magnet steel, described magnet steel is connected with described transmission shaft, the roof of described scrambler inner chamber is provided with a circuit board, be relatively set with magnetic inductor with described magnet steel on the described circuit board, described magnetic inductor and described magnet steel are provided with at interval.
Be provided with a scrambler base between described top cover and the described base, described top cover is fixedlyed connected by described scrambler base with described base.
Compared with prior art, effect intentionally of the present utility model is: 1. because a kind of single-ring encoder of the present utility model is connected with magnet steel on transmission shaft, above magnet steel, be provided with magnetic inductor, the magnetic signal that after transmission shaft rotates in the use magnet steel is produced changes, inductor finally converts thereof into digital quantity after gathering current magnetic signal in real time by certain frequency, thereby finish measurement to the mechanical rotation angle, because transmission shaft, do not produce mechanical wear when magnet steel and magnetic inductor work, performance is more stable, so the utility model is longer serviceable life, measuring accuracy is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: top cover 10, transmission shaft 12, base 14, scrambler base 16, scrambler inner chamber 18, magnet steel base 20, magnet steel 22, circuit board 24, magnetic inductor 26.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details
Referring to shown in Figure 1, a kind of single-ring encoder, the circular top cover 10, transmission shaft 12 and the base 14 that comprise lower ending opening, base 14 is set on the transmission shaft 12, be fixedly connected with a scrambler base 16 on the base 14, form scrambler inner chamber 18 after the openend of top cover 10 is fixedlyed connected with scrambler base 16.The end that transmission shaft 12 is positioned at scrambler inner chamber 18 is arranged with magnet steel base 20, magnet steel base 20 is provided with magnet steel 22, magnet steel 22 is connected with transmission shaft 12, the roof of scrambler inner chamber 18 is provided with a circuit board 24, be relatively set with magnetic inductor 26 with magnet steel 22 on the circuit board 24, magnetic inductor 26 and magnet steel 22 noncontact setting at interval.
The magnetic signal that after transmission shaft 12 rotates in the use magnet steel 22 is radially being changed, magnetic inductor 26 finally converts thereof into digital quantity after gathering the current magnetic signal that magnet steel 22 produces in real time by certain frequency, thereby finish measurement to the mechanical rotation angle, because transmission shaft, magnet steel and magnetic inductor do not produce mechanical wear when working, so performance is more stable.
Therefore the utility model serviceable life is long, measuring accuracy is higher.
The above only is a better embodiment of the present utility model; protection domain of the present utility model does not exceed with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (2)
1. single-ring encoder, comprise top cover, transmission shaft and be set in base on the described transmission shaft, after fixedlying connected with described base, described top cover forms the scrambler inner chamber, it is characterized in that: the end that described transmission shaft is positioned at described scrambler inner chamber is arranged with the magnet steel base, described magnet steel base is provided with magnet steel, described magnet steel is connected with described transmission shaft, the roof of described scrambler inner chamber is provided with a circuit board, be relatively set with magnetic inductor with described magnet steel on the described circuit board, described magnetic inductor and described magnet steel are provided with at interval.
