Description
Technical Field
The invention relates to switching between a gyro motor and a dynamic balancing machine, in particular to a switching device used between the gyro motor and the dynamic balancing machine.
Background
Gyroscopes operate by relying on the characteristics of the gyroscope, precession and dead-reclination, which requires the gyro motor rotor to run at high speeds in the gyroscope, and are therefore referred to as the "heart" of the gyroscope. The dynamic balance of the gyro motor is that the motor shaft is fixed on the support of the balancing machine, the dynamic unbalance vibration of the motor rotor is transmitted to the support through the bearing, the vibration sensor outputs the vibration signal, and the vibration signal is compared with the phase of the reference signal to determine the position and the size of the unbalance. And then reducing the unbalance amount to an allowable value by adopting a punching weight reduction mode.
Generally, because the gyro motor rotor is made of uneven materials and has errors in processing, assembly and the like, the rotor mass is asymmetrically distributed on a rotating shaft, and unbalanced alternating centrifugal force and alternating torque are further generated, so that the gyro motor generates vibration and accelerates the friction of a bearing, and the running life of the bearing of the gyro motor, the precision of a gyroscope and the working reliability of the gyroscope are directly influenced, therefore, the requirement on the dynamic balance precision of the gyro motor during high-speed rotation is very high, and the switching device between the dynamic balancer and the gyro motor is particularly important.
In order to ensure the universality of the dynamic balancing machine on gyro motors with various sizes, the width of the elastic support is generally wide, and therefore, a motor shaft of the gyro motor needs to be extended through a switching device so as to adapt to the width requirement of the elastic support. When the action is balanced, the gyro motor is switched with the dynamic balancing machine through the operation rod, the existing operation rod comprises an inner sleeve and an outer sleeve which are coaxially connected, the outer sleeve is in threaded connection with the inner sleeve, the inner sleeve is used for being connected with a motor shaft, and the outer sleeve is used for being connected with the dynamic balancing machine, so that the problems of the following three aspects can be caused:
first, the inner and outer sleeves of the operation rod are in threaded connection, so that the gyro motor shaft is difficult to ensure to be in a coaxial posture when being installed on a dynamic balancing machine, and the operation state of a motor bearing is further influenced, thereby causing the dynamic balance error of the gyro motor.
Secondly, because the width of the dynamic balancing machine support can not be adjusted, the transfer rods with different lengths need to be configured for the supports with different widths, the adjustable range of the existing transfer rods is limited, and if the adjustment is too long, the dynamic balance error becomes large, so that the balance between the length adjustment and the dynamic balance error is difficult to keep, and the universality is poor.
Thirdly, the running rod is frequently installed and replaced, and the precision of a motor shaft is easily damaged; and the operation rod is rigidly connected with the motor shaft, and when the gyro motor rotates, the reaction force generated by the operation rod on the motor shaft can damage the precision of the motor shaft.

one end of the inner screw is used for clamping a motor shaft, and the other end of the inner screw is an operating end;
the middle sleeve comprises a circular sleeve and a support tube with a semicircular section; the circular sleeve is coaxially connected with the supporting tube;
the circular sleeve is in threaded connection with the inner screw rod;
the outer lantern ring is in threaded connection with the circular sleeve, and the proportion range of the axial length of the outer lantern ring to the length of the whole adapter assembly is 2-3.5.
Furthermore, an annular handle is arranged at one end of the circular sleeve, which is far away from the supporting tube;
the annular handle is coaxially connected with the circular sleeve.
Further, the circular sleeve and the supporting pipe are of an integral structure.

2. The effective length of the whole switching assembly can be adjusted by adjusting the middle sleeve, so that the switching device can be suitable for gyro motors with various sizes, and the universality is improved.
3. The middle sleeve is composed of a circular sleeve and a semicircular supporting pipe, the semicircular supporting pipe is positioned at the bottom of the tight joint of the inner screw rod and the motor shaft, and the opening of the semicircular supporting pipe is upward; therefore, the support of the motor shaft is realized, and meanwhile, whether the inner screw rod is opposite to and clamped with the motor shaft is convenient to observe, so that the semi-open butt joint is realized; and the motor shaft only overlaps in semicircular stay tube, and the stress point of motor shaft is its terminal surface, therefore this switching device can not cause the damage to the motor shaft precision.
4. Compared with the existing running rod, the running rod reduces the time for installing the running rod by penetrating through the motor lead, and improves the working efficiency.
