Abstract
The utility model discloses a non-contact torque sensor which is composed of a linear Hall sensor, a signal processing circuit board, a magnet, a magnet ring, a rotatable pedestal, a swing shaft and a housing. The linear Hall sensor is arranged in the center of the signal processing circuit board. The signal processing circuit board is fixed on the housing. The magnet is fixed on the magnet ring. The magnet ring is fixed on the rotatable pedestal. The swing shaft is connected on the rotatable pedestal. The rotatable pedestal is arranged inside the housing. The non-contact torque sensor is simple in structure, high in compatibility, high in precision, wide in temperature use scope and high in anti-interference, and has no AC high frequency noise.
Description
Technical field
The utility model relates to a kind of non-contact torque sensor.
Background technology
Torque sensor be on various rotations or the non-rotary mechanical part to the detection of torsional moment perception.Torque sensor converts the physical change of torsion to accurate electric signal, can be applied in the manufacturing viscosity meter, electronic (pneumatic and fluid power) torque spanner, advantage such as it has, and precision height, frequency response are fast, good reliability and life-span are long.
In the prior art, the contact torque sensor that has used in a large number exists that serviceability temperature is restricted, anti-interference is poor, exchange the big defective of high frequency noise.Although existing multiple in the industry at present non-contact torque sensor technology is come out, related patent U.S. Patent No. also has a lot,, various non-contact torque sensors still can not solve the defective that above-mentioned contact torque sensor exists fully.
The base this, the inventor studies this, develops a kind of new non-contact torque sensor, this case produces thus.
The utility model content
The purpose of the utility model is to provide a kind of non-contact torque sensor, simple in structure to have, compatible strong, precision is higher, the temperature usable range is wideer, strong interference immunity with do not have the advantage that exchanges high frequency noise.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of non-contact torque sensor; Be made up of linear hall sensor, signal processing circuit board, magnet, magnet ring, rotatable pedestal, balance staff and shell, linear hall sensor is installed in signal processing circuit board central authorities, and signal processing circuit board is fixed on the shell; Magnet is fixed on the magnet ring; Magnet ring is fixed on the rotatable pedestal, and balance staff is connected on the rotatable pedestal, and rotatable pedestal is installed in the shell.
Offer perforation on the said shell, an end of balance staff passes perforation and is fixed on the rotatable pedestal.
Said balance staff is a Z font crank.
After adopting such scheme; The utility model is transmitted in rotatable pedestal by balance staff; Detect the magnetic field intensity of rotatable pedestal the different angles time through linear hall sensor; Provide through signal processing circuit board that the angle voltage signal is to the user accurately, the user can carry out converting effective torque signal to after the specific calculation process according to this voltage signal.
The utility model structural design is simple, and is compatible strong, can directly substitute the touch sensor that has used in a large number in the market, has higher precision and temperature usable range simultaneously; Magnet ring can effectively be isolated internal magnetic field and external magnetic field, makes product have higher anti-interference; Owing to adopt contactless signals collecting mode, can not produce the interchange high frequency noise of traditional touch sensor; By the special-purpose magnet that magnetic is processed, ability and linear hall sensor close fit reach lower temperature drift amount.

Label declaration
Shell 7 perforation 8.
Embodiment
A kind of non-contact torque sensor as shown in Figure 1, that the utility model discloses is made up of linear hall sensor 1, signal processing circuit board 2, magnet 3, magnet ring 4, rotatable pedestal 5, balance staff 6 and shell 7.
During the utility model work; Be transmitted in rotatable pedestal 5 by balance staff 6; Detect the magnetic field intensity of rotatable pedestal 5 the different angles time through linear hall sensor 1; Provide through signal processing circuit board 2 that the angle voltage signal is to the user accurately, the user can carry out converting effective torque signal to after the specific calculation process according to this voltage signal.
The above is merely the preferred embodiment of the utility model, is not the qualification to the utility model practical range, and all variation and modifications of doing according to the key points in design of the utility model all fall into its protection domain.
