Description

Gyro machine secondary dynamic balance test method and device

Technical field

The invention provides a kind of gyro machine secondary dynamic balance test method and device, be specifically related to field of machining and machinebuilding technology.

Background technology

For conventional single-degree-of-freedom integrating gyroscope, when the gyro machine of good dynamic balance is loaded into typical H type frame structure, motor shaft is arranged in the installing hole of framework, by screw, motor is pressed on framework with two briquettings, motor shaft is as stressed installation position, will inevitably be subject to assembly quality, physical dimension stability, structural rigidity, the impact of quality of fit etc., cause motor shaft to produce micro-distortion, when motor shaft produces after micro-distortion, the position that can cause motor nut changes, the relative position that has influence on motor pre-tightening power and bearing inner ring changes, also may make rotor cover produce distortion, directly cause the dynamic unbalance of motor to be destroyed.

The variation of the dynamic balancing degree of motor, make rotor produce centrifugal force with respect to the non-uniform mass of axis, this uneven centrifugal action can make rotor produce periodic mechanical oscillation on bearing, in bearing, cause an additional dynamic pressure, make operational reliability and the precise decreasing of motor, and produce noise thereupon, reduce bearing life.In addition, the vibration that this unbalance dynamic produces, also can cause the continuation of dynamic unbalance to increase; Dynamic unbalance also can cause that bearing produces heavy wear in time and affects life-span of motor, simultaneously, bearing produces in time heavy wear meeting and further causes the continuation in time of motor degree of unbalance to increase, and then cause gyroscopic drift rate to increase in time, thereby further affect gyrostatic precision and performance.

Summary of the invention

The invention provides a kind of gyro machine secondary dynamic balance test method and device, by gyro machine is carried out to dynamically balanced detection and correction together with H type frame installation, after mainly having solved moment gyroscope motor and H type frame installation, dynamic balancing is destroyed, cause motor reliability and precise decreasing, bearing life reduces, the problems such as gyro machine middle (center) bearing serious wear.

Concrete solution of the present invention is as follows:

This gyro machine secondary dynamic balance test method, comprises the following steps:

1] gyro machine is directly mounted to the V-type location notch on dynamic balancing machine;

2] gyro machine being carried out to dynamic balancing at least one times detects and proofreaies and correct;

3] after the gyro machine and the fixed installation of H type framework by dynamic balancing detection and after proofreading and correct, at the motor shaft two ends of gyro machine, two locating shafts are installed respectively, the axiality of two locating shafts is less than 0.03mm, then two locating shafts is mounted to the V-type location notch on dynamic balancing machine;

4] gyro machine being arranged on H type framework is carried out the detection of dynamic balancing at least one times and proofreaied and correct, until meet the demands.

This gyro machine secondary dynamic balance detecting device, it is characterized in that: comprise the H type framework for gyro machine is installed and be fixedly mounted on two locating shafts on H type framework, the motor shaft two ends of described two locating shafts and gyro machine are coaxially connected and axiality is less than 0.03mm; Described locating shaft comprises the supporting section and the linkage section that are fixedly connected with; Described linkage section is screw rod; The screwed hole of described screw rod and H type framework is suitable; Described supporting section size is mated with V-type location notch.

This kind of gyro machine secondary dynamic balance detecting device, is characterized in that: comprise H type framework and be fixedly mounted on two locating shafts on H type framework, the motor shaft two ends of described two locating shafts and gyro machine are coaxially connected and axiality is less than 0.03mm; Described locating shaft comprises the supporting section and the linkage section that are fixedly connected with; Described linkage section is for connecting folder; The groove spot size of described connection folder and the external dimensions of H type framework are suitable; Described connection folder is spirally connected with H type framework; Described supporting section size is mated with V-type location notch.

The invention has the advantages that: the present invention has carried out dynamically balanced detection and correction for the second time after to gyro machine and H type frame installation, improve the dynamically balanced precision of motor under actual application environment, guarantee the in use stability of dynamic balancing degree of gyro machine, increased the useful life of gyro machine simultaneously.
