The utility model content
The purpose of this utility model is to design a kind of high-speed electric main shaft bearing performance multi-function test stand, so that further improve the performance index of electric mainshaft bearing, improves the greasy property of lubricant medium to movable body, prolongs the serviceable life of movable body.
The scheme that provides according to the utility model, one end of rotating shaft is connected with high-frequency motor spindle, the other end stretches in the housing, cushion is set in housing, the inner chamber of housing is divided into test portion and exerts pressure part, on the housing wall of part of exerting pressure, pressure oil is set and imports and exports, the pressure block that contacts with cushion is set in test portion.
Exert pressure the part housing wall on lubricating oil inlet is set, acceleration is taken into account thermopair.End at housing is provided with end cap, between end cap and housing cushion is set, and pressure oil is imported and exported and is positioned on the end cap.Rotating shaft utilizes flexible coupling to be connected with high-frequency motor spindle.On high-frequency motor spindle, connect cooling device and lubricating oil inlet.The oil return interface is set on housing.
The utility model has the advantages that: after using this testing table, can carry out electric steel for main shaft system bearing and ceramic bearing under all kinds of lubricating systems such as grease lubrication, oil lubrication, oil spray lubrication and oil-air lubrication lubrication mechanism and the technical research of life-saving, the projects such as dynamic property that simultaneously can test electric mainshaft bearing, so that further improve every performance index of electric mainshaft bearing, improve the greasy property of lubricant medium, prolong the serviceable life of movable body movable body.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As shown in the figure: an end of rotating shaft 2 is connected with high-frequency motor spindle 11, the other end stretches in the housing 14, cushion 6 is set in housing 14, the inner chamber of housing 14 is divided into test portion 18 and exerts pressure part 17, pressure oil is set on housing 14 walls of the part 17 of exerting pressure imports and exports 8, the pressure block 16 that contacts with cushion 6 is set in test portion 18.During work, earlier be positioned at installation bearing 3 to be tested on a section of the part 18 of exerting pressure, and bearing 3 is contacted with pressure block 16 in rotating shaft 2, actuating motor, give rotating shaft 2 by electric main shaft 11 with transmission of power, drive bearing 3 rotations, simultaneously, pressure oil enters in the part 17 of exerting pressure, under the effect of pressure, cushion 6 produces distortion, is moved to the left, promote pressure block 16 and move to left, bearing 3 is exerted pressure.According to different pressure and rotating speed, can detect the various mechanical performance index of bearing 3.
Lubricating oil inlet and condensing mouth 4, accelerometer 5 and thermopair are set on the housing wall of test portion 18.Lubricating oil inlet is connected with oil gas generator 13, so that bearing 3 is applied various lubricant medium, checks the lubricant effect of various lubricant medium to bearing 3; Accelerometer 5 is connected with vibration analyzer 7, is used for the vibratory output of check bearing 3, and thermopair is connected with temperature measurer 9, is used for the temperature rise situation of check bearing 3, and the temperature of bearing 3 and vibratory output are the major parameters of evaluation high-speed bearing greasy property.
In the end of housing 14 end cap 15 is set, at end cap 15 and 14 of housings cushion 6 is set, pressure oil is imported and exported 8 and is positioned on the end cap 15.When needs test bearing 3, can earlier end cap 15 be pulled down, again bearing 3 is installed in the rotating shaft 2, with end cap 15 pressure block 16 and cushion 6 are fixed again.Rotating shaft 2 can utilize flexible coupling 1 to be connected with high-frequency motor spindle 11, to avoid damaging high-frequency motor spindle.On high-frequency motor spindle 11, can connect cooling device 12 and lubricating oil inlet 13, so that high-frequency motor spindle 11 is implemented cooling with lubricated.Oil return interface 10 is set, so that in needs, the lubricating oil of accumulation in housing 14 is bled off on housing 14.
