Abstract

The invention relates to a dynamic balancing test device of a rigid double-disk rotor, which is characterized in that a bearing block is fixed on an elastic support; the lower end of a supporting arm is fixedly connected with the elastic support; a photoelectric displacement sensor is installed on the supporting arm and the elastic support, the bearing block, the supporting arm and the photoelectric displacement sensor combine an overall supporting block jointly; a rotating shaft is installed on the elastic support via the bearing block; one end of the rotating shaft is connected with a motor by a coupling; the motor is installed on a motor base; symmetrical left and right balancing disks are arranged on the rotating shaft; a transparent shield is capped outside the left and right balancing disks; the motor base, the transparent shield and the elastic support are bolted on a base; the lower end of the base is provided with a shock strut. The elastic support, the bearing block, the supporting arm and the photoelectric displacement sensor of the invention combine an overall supporting block jointly, thus shortening the distance between the photoelectric displacement sensor and the test point, contributing to good connection rigidity, reducing vibration disturbance and increasing measuring accuracy.

Description

technical field [0001] The invention relates to an experimental device for performing dynamic balancing operation on a rotating mechanism, in particular to a double-disk rigid rotor dynamic balancing experimental device. The device is equipped with two balance discs on a fixed rotating shaft. Background technique [0002] At present, the rotors of many high-speed rotating equipment in engineering are not ideal symmetrical rigid bodies, and there are errors in the installation of bearings. Therefore, an unbalanced inertial force will be generated during work, causing a large bearing constraint. There are many types of large and small dynamic balance experiment equipment, but the structure is generally complicated and the operation is inconvenient. There are few dynamic balance experiment devices suitable for experimental teaching in colleges and universities. At present, there is a four-disk rigid rotor dynamic balance experimental equipment that can be operated independentl...
