The measuring device and the measuring method of the operation temperature of the motor bearing are a fastening and positioning device and the measuring method of the operation temperature of the bearing, which utilize a thermoelectric couple to measure the operation temperature of the bearing through the oil filling hole; the measuring device of the operation temperature of the motor bearing is formed by a pressing screw sleeve, a fastening rubber ring, a pressing nut and a connecting rod, and is the fastening and positioning device for measuring the operation temperature of the motor bearing. The measuring device and the measuring method are characterized in that 1, the measuring device utilizes the pressing nut, the pressing rubber ring and the pressing screw nut to position and fasten a temperature measuring rod of the thermoelectric couple; and 2, the bottom end of the temperature measuring rod is better contacted with the inner wall of the oil filling holt through the temperature measuring device and an oil filling pipe to measure the operation temperature of the bearing.
Description
Technical field
The present invention relates to the electromechanical testing field, be specially adapted to H280～560 with the bearing operation temperature survey of oil hole motor.
Background technology
It is existing historical for many years that our company produces middle-size and small-size threephase asynchronous, and motor performance is good, firmly gets user's trust.But the test of the bearing temperature rise of threephase asynchronous is the measurement mechanism of special use never, any temperature of the outer tegillum of the warm instrumentation examination of point commonly used motor is as bearing temperature during test, cause that error reaches 5～10 ℃ between probe temperature and the actual temperature, this problem perplexs us for many years always, by designing this device, adopt thermopair, by oil hole close-in measurement motor bearings outer ring temperature, make and measure that error is controlled at 2 ℃ between temperature and the actual temperature, improve the accuracy of test, solved this difficult problem:
1) to the measurement mechanism of motor bearings operating temperature without special use, motor is with any temperature of the outer tegillum of the warm instrumentation amount motor of point during as bearing temperature, because the position chosen is different and the impact of extraneous factor, cause between measurement data and the real data deviation larger.
When 2) directly measuring the bearing operation temperature with thermopair by oil pipe, the vibration during owing to motor rotation and the impact of fan, the easy and oil hole bottom disengaging in tempilstick bottom causes measurement data inaccurate.
For above weak point, we absorb all the useful ideas, and invention has designed motor bearings operating temperature measurement mechanism and measuring method, have improved the accuracy of test, have solved problem, have guaranteed the controllability of product quality.
Summary of the invention
Measure problem for solving the motor bearings operating temperature, invented a kind of delicate structure, easy for installation, the easy motor bearings operating temperature measurement mechanism of operation.And provide a kind of bearing oil hole inner wall temperature of measuring as the bearing operation thermometry of bearing temperature by this device.
The technical scheme that technical solution problem of the present invention adopts is:
Motor bearings operating temperature measurement mechanism and measuring method are to utilize thermopair, carry out the thermometric fastening positioning device of bearing operation and bearing operation thermometry by oil hole, motor bearings operating temperature measurement mechanism is by gland nut, fastening cushion rubber, gland nut and connecting link form, and are the measurement and positioning fasteners of motor bearings operating temperature.It is characterized in that: 1. measurement mechanism utilizes gland nut, and fastening cushion rubber and gland nut position with fastening the tempilstick of thermopair.2. tempilstick is by temperature measuring equipment and oil fuel tube, and bottom and oil hole inwall good contact are measured the bearing operation temperature.
The invention has the beneficial effects as follows:
1) motor bearings operating temperature measurement mechanism can directly be tested H250～560 seat No. by oil hole, with the bearing temperature of oil hole motor, does not need in addition machining bearing thermometer hole again.
2) measurement mechanism plays radial location and axially fastens double action tempilstick, and the tempilstick bottom is contacted well with the oil hole inwall, guarantees the accuracy of measuring.
3) motor bearings operating temperature measuring method is measured the motor bearings operating temperature by oil hole.During bearing operation, temperature is directly transferred to the outer tegillum of bearing by bearing outer ring and bearing with end cover chamber.The inboard bottom of oil hole tegillum outside bearing, little with bearing outer ring and bearing with end cover chamber distance, be subjected to the external environment factor affecting little, the bearing temperature in the time of well reacting bearing operation.
