Abstract
The invention discloses a magnetic coupling comprising a magnetic rotor with an infrared temperature dynamic detection alarms. The magnetic coupling comprises the magnetic rotor (1), a copper rotor (2) and a permanent magnet (4) arranged in the magnetic rotor (1). The infrared temperature dynamic detection alarm is arranged outside the magnetic rotor (1). In the magnetic coupling comprising the magnetic rotor with the infrared temperature dynamic detection alarm, after being arranged outside the magnetic rotor, the infrared temperature dynamic detection alarm can detect the temperature of the magnetic rotor at any time, and when the temperature of the magnetic rotor reaches a set value, the infrared temperature dynamic detection alarm gives an alarm and a system can be powered off according to the alarm or a worker can deal with the problem of the system to ensure that the temperature of the permanent magnet in the magnetic coupling may not exceed a Curie point to avoid the demagnetization and working incapability of the magnetic coupling.
Description
Technical field
The present invention relates to a kind of magnet rotor has the magnetic coupling of infrared temperature detection of dynamic alarm.
Background technology
With permanent magnetism power can transfer torque be the technology of knowing altogether, magnetic coupling is based on the actuated element of a kind of transferring power of this technology, one side of magnetic coupling is the permanent magnet (title magnet rotor) that polarity arranges according to certain rules to be installed and opposite side is equipped with copper dish (title copper rotor), when power drives the copper rotor rotation, the magnetic line of force by copper dish cutting permanent magnet, on the copper dish, produce eddy current, and the magnetic field interaction of the magnetic field of eddy current and permanent magnet makes magnet rotor rotate with copper rotor, gapped between them without any mechanical connection, they respectively with engine, working machine connects, just can give engine with the transmission of power of engine, in the process of transferring power, between magnet rotor and the copper rotor speed discrepancy is arranged, its speed discrepancy can produce heat, permanent magnet is a rare earth metal, it has a Curie point, and the heat that produces when speed discrepancy can not balance and when making the temperature of permanent magnet surpass Curie point, permanent magnet is with loss of excitation.
Summary of the invention
The purpose of this invention is to provide a kind of magnet rotor has the magnetic coupling of infrared temperature detection of dynamic alarm.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of magnet rotor has the magnetic coupling of infrared temperature detection of dynamic alarm, comprise magnet rotor (1), copper rotor (2) and be arranged on permanent magnet (4) in the magnet rotor (1), it is characterized in that: described magnet rotor (1) is outside equipped with infrared temperature detection of dynamic alarm.
When rotated, the copper dish of copper rotor (2) cuts the magnetic line of force of permanent magnet (4) in the magnet rotor (1) respectively.
Be provided with gap (3) between described magnet rotor (1) and the copper rotor (2).
A kind of magnet rotor of the present invention has the magnetic coupling of infrared temperature detection of dynamic alarm; when the copper dish cuts the magnetic line of force of permanent magnet in the magnet rotor by the engine driven rotary; just on the copper dish, produce eddy current; and the magnetic field interaction of the magnetic field of eddy current and permanent magnet makes magnet rotor rotate with copper rotor; in the process of transferring power, between magnet rotor and the copper rotor speed discrepancy is arranged; if the heat that speed discrepancy produces can not balance then can make the temperature of permanent magnet raise; after infrared temperature detection of dynamic alarm is set outside magnet rotor; infrared temperature detection of dynamic alarm can detect the temperature of magnet rotor at any time; infrared temperature detection of dynamic alarm can be reported to the police when the temperature of magnet rotor reaches set point; system can shut down according to reporting to the police or by the problem that staff's disposal system occurs, guarantee that the temperature of permanent magnet in the magnetic coupling can and can't not be worked above the Curie point loss of excitation.
