SU210841A1 - SUSPENSION OF THE SENSITIVE ELEMENT OF THE DEVICE - Google Patents

Description

The known nodes of the sensitive element of the device contain supports, made on two cores mounted on the sensitive element, fixed and movable padding, two shock-absorbing springs. These pendants cannot be used in float devices, do not provide perception of fluid loads, do not reduce friction in the supports, do not allow centering of the sensitive element in any of its positions, and do not eliminate axial play.

The proposed suspension eliminates these drawbacks due to the fact that in one of the supports inside the damping spring, there is a floating bushing and a spring of low rigidity.

Pa drawing shows the described suspension.

Girozel /, suspended in a liquid, is located in the housing 2 of the gyroscope and has a suspension on self-centering core supports. The cores 3, made of cobalt – tungsten alloy and pressed into the body of the gyro, are supported by spherical superstructures on the spherical surfaces of the bolsters. The latter are pressed into the sleeves 5 and 6. The sleeve 5, under the action of the spring 7, presses the follower 4 to the core 3, the centrifuge of the girousel, and easily moves with small forces on the side of the core. The weak spring 7 serves to center the gyro in any position in space and practically does not create friction in the core.

The operation of the girder's suspension proceeds in two modes: static and dynamic. In the static mode, the girode makes oscillations insignificant in amplitude and frequency around the longitudinal axis l: -x, and only the residual weight and trim of the girder act on the side of the core. Under this force, the spherical surface of the core of the podsti core is until the component of the reaction from the side of the subtick, pressed by the spring, balances this force. The movement of the axis, and hence the friction radius, will be insignificant, since the residual weight and trim are small in size. The moment of friction in the support, despite the pressure from the spring-loaded plate, will be less than the moment of friction in the cylindrical trunnions.

In the dynamic mode, the gyro node oscillates around the xx axis, as a result of which gyroscopic and hydrodynamic forces arise which, through cores, tend to put pressure on the stone stones. Since one of the pods can move, the main pressure will be perceived by the damping fluid through the surface of the gyro, i.e. liquid friction will occur. Thus, even with a significant 9

At an increase in the alternating pressure of the girule, the moment of friction will increase slightly.

Subject invention

The suspension of the sensing element of the device, containing supports made on two cores mounted on the sensitive element, fixed and movable bumpers, two damping springs, characterized in that, in order to allow the suspension to be used in float instruments, to absorb the loads of fluid, friction in the supports, centering the sensing element in any position and eliminating axial play, in one of the supports there is a floating sleeve and a small spring inside the damping spring stiffness.
