Abstract

PURPOSE:To obtain a cheap vibration isolator which is resistive to heat, oil, and fatigue; and capable of being made small-sized by constituting it so that the compression force and shearing force are applied from the side face of a helical spring. CONSTITUTION:A female screw-like groove coupled with a helical spring 3 is provided at one side face of a supporter 1 and a main body 2, and the helical spring 3 is coupled with this groove to be pinched by the supporter 1 and main body 2. The vertical oscillation displacement applied to the supporter 1 generates a compression force as a pressing force of the side face of the helical spring 3, and the horizontal oscillation displacement generates a shearing force as a force shifting the helical spring 3 held in the female screw-like groove. The helical spring 3 provides a vibration isolation action by absorbing the displacement applied from sideward.

As shown in the figure, a contraction force is generated as a force that presses the side of the spring (3), and the vibration level in one direction of the water 11 is changed as shown in Fig. 3. ) is generated as a force to shift the force. Similarly, there is no figure 4...It becomes a Y force.

The difference is that the sensor acts on the pressing force from the side as shown in the figure 4, and there is a female thread shape that fits and contacts the side surface of the helical spring. The friction with the groove and the damping effect due to the oil film between the grooves are also used together.

る長所がある。Compared to conventional vibration isolators using rubber, etc., this device is resistant to heat, oil, and fatigue, the vibration isolation characteristics can be easily adjusted by adjusting the spring arrangement direction and length, etc., and the manufacturing cost is low and small. It has the advantage of being able to be transformed.
