Description
Technical field
The present invention relates to the air-bearing field tests, especially a kind of conical air floating shaft holds the axial carrying force test device.
Background technology
Along with the development of science and technology, often adopt gas lubrication to replace common power lubrication, air-bearing is exactly gases at high pressure to be introduced in the object gap of relative motion form air film, and avoiding directly, contact realizes frictionless motion.
Air-bearing has the characteristics such as speed is high, precision is high, low in energy consumption, the life-span is long as a newtype of sliding bearing.Air-bearing not only can be realized axial rotation, also can be applied to axial movement, according to the difference of its application multiple classification is arranged.Because the air film between air-bearing shafts and the air supporting cover is very thin, so very high to the component processing accuracy requirement, therefore it is little that also there is carrying in air-bearing, rigidity is low, the shortcomings such as poor reliability, for satisfying industrial circle to the requirement of air-bearing, need to carry out the properties test to air-bearing, whether meet processing request with the check air-bearing, be that 201010180373.3 " a kind of device for detecting performance of static-pressure air bearing " just proposed a kind of different geometries static-pressure air bearing that can detect under different supply gas pressures and different air-film thicknesses, the pressure distribution of gas in the load-bearing capacity of bearing and rigidity and the bearing such as application number; Application number is that 201010530570.3 " device for testing stiffness of air-bearing " can test the rigidity of single air-bearing and the rigidity of combined air flotation bearing.The load-bearing capacity of air film between two air bearing surface when but these two kinds of proving installations all can only test out static state.
For a kind of taper air supporting without the friction cylinder, air-floatation planar is tapered, Force decomposition between air film is for radially and axial direction, therefore, conical air floating shaft holds the axial float that can prevent air-bearing shafts, therefore but the load-bearing capacity of air film is limited, need to test the axial carrying capacity of air-bearing, do not have in the industry at present a kind of feasible, be applicable to conical air floating shaft and hold axial carrying force test device and testing standard.
Summary of the invention
Can't realize the deficiency of the anti-side direction aptitude tests that conical air floating shaft holds in order to overcome prior art, the load maintainer that the invention provides a kind of power does not directly contact with air-bearing, detection of dynamic, easy to operate conical air floating shaft are held the axial carrying force test device.
The technical solution adopted for the present invention to solve the technical problems is:
The axial test of bearing capacity device of a kind of taper air bearing, comprise electromagnet, power sensor, ferromagnet, moving beam, support and base, described conical air floating shaft holds fixed placement on base, described ferromagnet is sleeved on the upper end of conical air floating shaft, described electromagnet is installed on the moving beam, and described electromagnet is positioned at the top of conical air floating shaft, the installation site of described electromagnet is concentric with conical air floating shaft, strong sensor is installed between described electromagnet and the moving beam, described support vertically is fixed on the base, and described moving beam is fixedly connected with support.
Further, described support is provided with the adjustment hole of adjusting upper-lower position for moving beam.
Further again, described ferromagnet is pig iron head.Also can adopt other can be by the ferromagnet that magnet held.
Technical conceive of the present invention is: do not introduce other external force when conical air floating shaft rotates, produce magnetic fields on pig iron ring by electromagnet, applied the power along its axial direction for the conical air floating shaft top, be not in contact with one another between electromagnet and the conical air floating shaft, do not affect the motion state of conical air floating shaft.Come the slowly size of increasing action power on air-bearing shafts by the size of regulating magnet coil current, range of adjustment is large, precision is high.
This programme has utilized the magnetic force principle to realize, described ferromagnet refers to produce the material of the strong complementary field identical with external magnetic field under magnetic fields, described ferromagnet comprises iron-cobalt-nickel etc., attract behind its magnetic force that can be produced by electromagnet, the electromagnet of described belt coil can change by the size that change passes into electric current the size of magnetic force.
This proving installation is only applicable to the conical air floating shaft that aluminum alloy materials etc. do not affect by electromagnet and holds.
Beneficial effect of the present invention is mainly manifested in: the load maintainer of power does not directly contact with air-bearing, detection of dynamic, easy to operate.
