    摘要: A vibration-sensing gyro composed of a light alloy such as duralumin includes a base and a first pair of tines projecting parallel to each other from the base. Piezoelectric elements are mounted on the root of the side faces of the first pair of tines to excite the first pair of tines along an X axis. The vibrations of the first pair of tines along the X axis are then propagated to a second pair of tines to vibrate the second pair of tines along the X axis. Piezoelectric elements are mounted on the root of the upper and the lower faces of the second pair of tines to detect vibrations of the second pair of tines along an Y axis. When the second pair of tines receives the Coriolis force based on an angular velocity .omega. around a Z axis and vibrates along the Y axis, the vibrations along the Y axis are detected as electric signals (alternating current voltages) by piezoelectric effects of the piezoelectric elements.

    摘要: The invention provides a vibration-sensing gyro, where resonance frequencies of tines are adjusted adequately in a simple manner. A vibration-sensing gyro (10) of the invention is made of a light alloy plate like duralumin and includes a first tine (14) and a second tine (16) disposed parallel to each other and projecting from a base (12). When the first tine (14) has a length l1, a width w1 along the X axis, and a thickness t1 and the second tine (16) has a length l2, a width w2 along the X axis, and a thickness t2 (=t1), the first tine (14) and the second tine (16) hold the relationship of l2/.sqroot.t2=l1/.sqroot.w1. In other words, the tines (14,16) and the base (12) are manufactured to satisfy this relationship. Such definition of the dimensions makes a resonance frequency fx1 of the first tine along the X axis coincide with a resonance frequency fy 2 of the second tine 16 along the Y axis.

The gear mechanism is formed by disposing the plurality of spur gears in the meshed state with each other. The screw-like gears (2) and (4) are disposed on the same axis as the spur gears (1) and (3) in the meshed state with each other. The screw-like gears (2) and (4) adjacent to each other are formed in screw shapes having lead angles extending in the reverse directions to each other and equal in angle to each other. The spur gear (1) and the screw-like gear (2) are rotated integrally with each other to transmit its rotation to the spur gear (3) and the screw-like gear (4) adjacent to each other.
