CALCULATING DEVICE

摘要

The inventive calculating device can be used for measuring engineering, instruments and devices comprising a calculating mechanical mechanism: induction meter, water, fuel and distance meter etc. The inventive calculating device is characterised in that a reverse rotation stopper of wheels (1,2,3,4,5) comprises a wheel (1) and a pinion (7) interacting therewith and receiving the movement of rotation thereof. Said wheel (1) is provided with a projection (19) on one side thereof and a slot (20) disposed therebehind in a direction of the reverse rotation of the wheel. In the alternative embodiment, the length of the long teeth (13.1, 13.2, 13.3) of the pinion (7) and the length of the slot (20) of the wheel (1) are increased of more than the length of a projection (19) of the wheel (1). Said inventive device makes it possible to reduce the friction of the mechanical transmission thereof, thereby increasing the certainty of readings of the device provided with the reverse rotation stopper.
