Optimized technical scheme, said bearing are provided with two, and two bearings lay respectively at the mandrel two ends, are provided with the space that is used to admit fan between two bearings, and two bearings are connected on the same base through bolt; The rolling bearing rotational support that said mandrel is provided with through two ends is on two bearings, and mandrel forms rotating speed such as coaxial cable and is connected with the motor shaft of frequency control motor, and frequency control motor is fixedly connected on the base through electric machine support.Mandrel and fan are by the seat supports at two ends, and mandrel is difficult for taking place deflection deformation, and test bench running is steady, little, the long service life of vibrations; The bearing of frequency control motor and support mandrel and fan is fixed on the same base, and simple in structure, compact, is beneficial to the reduction manufacturing cost, and is beneficial to the integral rigidity that improves testing table, increases the service life.
Further optimized technical scheme; Said bearing forms the structure of split up and down by first bearing and second bearing; Second bearing is fixedly connected with base; First bearing is fixedly connected through coupling bolt with second bearing, and the axial line of said mandrel is positioned on the faying face of first bearing and second bearing formation, and mandrel and motor shaft form transverse splicing through the convex-concave fit structure that is provided with between the two.Mandrel and motor shaft through between transverse splicing be convenient to install or when dismantling mandrel and fan, but the vertical direction lifting is easy to operate, is beneficial to shorten test setup time, reduces experimentation cost, is applicable to the fan test that weight is heavier.
Optimized technical scheme, said mandrel are provided with the shaft shoulder through the axial play of bearing inner race restriction rolling bearing, are provided with the gland through the axial play of bearing outer ring restriction rolling bearing at the other end of rolling bearing, and gland is connected through screw retention with bearing.Do not produce axial float through restriction bearing axial float respective limits mandrel yet, and then guarantee that axial float does not take place fan, guarantees accuracy of experimental results in process of the test.
Further optimized technical scheme, said testing table also is provided with safty shield, and safty shield covers on frequency control motor and fan is outside.Safty shield can be guaranteed testing crew and external unit safety.
The utility model beneficial effect compared with prior art is, the limit speed that can be used for the unpowered cooling fan of logical machine changes and following bench tests at per minute 12000, and simple in structure, easy to operate, experimentation cost is low, safe in utilization.
