Abstract
The utility model discloses a phase output magneto-electric speed sensor, which consists of two or more speed measuring magnetic heads. The magnetic heads are assembled on a bracket. When the rotary body rotates, the pulse signals put out by the magnetic heads have different phases. By calculating and comparing the many pulse signals put out by the magnetic heads, the rotation speed and direction of the rotary body can be measured out.
Description
One, technical field
The utility model belongs to a kind of magnetoelectric transducer, especially for the magnetoelectric transducer of measuring rotary body speed of rotation and sense of rotation.
Two, background technology
At present, be widely used in the tachometric survey magnetoelectric transducer of vehicle and all kinds of slewings, all have only a tachometer head.When the tooth top of the gear that tested the speed, when teeth groove replaces inswept transducer magnetic head, sensor output near sinusoidal pulse signal, its output frequency is directly proportional with tested rotary body rotating speed, can obtain speed of rotation after calculating, but can't measure the sense of rotation of rotary body.
Three, summary of the invention
Goal of the invention of the present utility model provides a kind ofly both can measure the rotary body speed of rotation, can measure the phase place output magnetoelectricity speed pickup of sense of rotation again.In order to realize goal of the invention of the present utility model, the technical solution adopted in the utility model is: this sensor is made up of mounting bracket and two or more tachometer head, and tachometer head is fixed on the mounting bracket.When rotary body rotated, the pulse signal of tachometer head output had different phase places, by the pulse signal that calculates and more a plurality of tachometer head is exported, can measure the speed of rotation and the sense of rotation of tested rotary body.
Four, description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the output waveform figure of the utility model measurement when being rotated in the forward.
Output waveform figure when Fig. 3 is the utility model measurement reverse rotation.
Five, concrete embodiment
The utility model is made up of mounting bracket 1 and two tachometer head T1, T2, and two tachometer head T1, T2 are fixed on the mounting bracket 1, and the distance between two tachometer head T1, the T2 is 3/4 of the tooth pitch Δ of the gear 2 that tested the speed.
When being tested the speed gear 3 when being rotated in the forward, the output pulse signal of two tachometer head T1, T2 as shown in Figure 2, the phase place of the pulse signal of tachometer head T1 output is than leading 90 ° of the pulse signal phase place of tachometer head T2 output; When being tested the speed gear 3 reverse rotations, the output pulse signal of two tachometer head T1, T2 as shown in Figure 3, the phase place of the pulse signal of tachometer head T1 output is than 90 ° of the pulse signal phase lags of tachometer head T2 output.By calculating and compare the pulse signal of the output of two tachometer head T1, T2, can measure the speed of rotation and the sense of rotation of the gear 2 that tested the speed.
Claims (2)
1, a kind of phase place output magnetoelectricity speed pickup is made up of mounting bracket (1), tachometer head (T), and tachometer head (T) is fixed on the mounting bracket (1), it is characterized in that tachometer head (T) is two or more.
2, a kind of phase place output magnetoelectricity speed pickup according to claim 1 is characterized in that described tachometer head (T) is two, and the distance between two tachometer heads (T1, T2) is 3/4 of the tooth pitch of the gear (2) that tested the speed.
