The utility model content
The purpose of this utility model with the defective that exists at prior art, a kind of single span rotor experimental provision is provided, meet the modern teaching requirement, simple in structure, easy to operate.
For achieving the above object, the utility model adopts following technical proposals:
A kind of single span rotor experimental provision comprises by direct current generator and rotating shaft, it is characterized in that:
1) output shaft of described direct current generator connects described rotating shaft through a shaft coupling;
2) described tested rotating disk is fastened in the described rotating shaft by the holding screw that its symmetria bilateralis distributes;
3) described rotating shaft is supported by two connecting base bearing single spans, and described connecting base bearing is fixed on the bearing spider; Described bearing spider is mounted on the T type groove platform by screw;
4) described direct current generator is electrically connected a machine governor;
5) on described T type groove platform, fixedly mount a sensor stand by magnetic force, a current vortex sensor probe is installed near described rotating disk on this support, described electric vortex displacement sensor probe connects the eddy current displacement sensor fore-lying device, and the output of this eddy current displacement sensor fore-lying device is connected to a computing machine through a data capture card.
Above-mentioned direct current generator is fixedly mounted on the T type groove platform by a motor bearing.
The utility model has following conspicuous substantive distinguishing features and advantage compared with prior art:
This single span rotor arrangement has been compared special advantages as experiment device for teaching than some single span rotor experiment table: 1, experiment content horn of plenty more.Can be by changing this experimental system shaft coupling rigidity, rotating shaft diameter and span, supporting way, rotating disk quality, position, quantity etc., can be combined into the experimental system of different critical rotating speed, thereby make the experimenter all can observe, test and analyze multiple experiment condition; 2, can design, select and make up dismounting by the experimenter voluntarily, deepen the understanding of experimenter the critical rotor speed notion.3, can adopt the Labview program to carry out data processing in this single span rotor experimental provision computing machine, make experiment more directly perceived, meet the demand of modern teaching more.This single span rotor experimental provision can be the student and carries out education experiment, and the student designs voluntarily, selects in person, assembles, tests, observes and analyzes by this experiment, has deepened the understanding to the critical rotor speed notion, has good teaching effective.
The utility model provides the single span rotor that is used for experimental teaching experimental provision, can by the student voluntarily design team take on many experimental provisions, thereby carry out the experiment and the analysis of rotating speed, amplitude, critical rotary speed.Simple in structure, easy to operate, practical reliable.
