Being explained as follows in relation to technical term and prior art component in above content:
Torque sensor: also known as torque sensor, torsion sensor, torque sensor or torquemeter are divided into dynamic and static state two
Major class, wherein dynamic torque sensor can be called torque sensor, torque rotary speed sensor, non-contact torque sensor, rotation again
Torque sensor etc.；Wherein static torque sensor mainly has foil gauge torque sensor.Torque sensor is to various rotations
Turn or non-rotary mechanical component on to torsional moment perception detection.The physical change of torsion is converted into accurately by torque sensor
Electric signal.
Foil gauge torque sensor: mainly including the structures such as elastic shaft, measuring bridge, instrumentation amplifier, interface circuit；

Formula measuring device is connect, mechanical, electrical, magnetic, light and the methods of hybrid manufacture can be used；By the difference of signal form, revolution speed sensing
Device can be divided into analog and two kinds digital.
Hall-effect speed sensor: being made of the principle using Hall effect.Hall effect refers in a rectangle half
There is an electric current to pass through in conductor sheet, is also acted on the semiconductor material if any a magnetic field at this time, then perpendicular to electric current side
To semiconductor both ends, the voltage of a very little can be generated, which is known as Hall voltage.It senses made of the magnetic material
Double wedge on device rotor alternately across permanent magnet gap when, just have a changing magnetic field and act on Hall element,
Hall voltage is set to generate pulse signal；It can be detected revolving speed according to generated pulse number.
Shaft coupling: shaft coupling refers to two axis of connection or axis and revolving meber, turns round together in passing movement and dynamic process,
A kind of device not disengaged under normal circumstances.Sometimes also it is used to prevent coupled parts receiving excessive as a kind of safety device
Load, play the role of overload protection.Common shaft coupling has been standardized or standardizes mostly, only needs under normal circumstances just
It really selects the type of shaft coupling, determine the model and size of shaft coupling.Shaft coupling can be divided into positive coupling and flexible coupling
Two major classes.
