Thus, even if periodically changing the steering shift must be unacceptable, such an unbalanced pawl mechanism can have such an effect on the shifting speed that an incorrect indication of consumption may occur

Embodiment Construction

[0024] Figure 1 shows a cross-sectional expanded view of a one-way counter. The expanded diagram means that all counter axes are drawn on a plane, even though they are not actually configured in this way. However, in order to clarify which gears of the counter directly mesh with each other, that is, drive each other, the figure shows two operatively connected arrows 22 and 23.

[0025] The counter shown in Figure 1 is a roller type. For the sake of simplicity, only one roller numbered 3 is symbolically used as an indicator in the figure, and multiple numbered rollers are arranged adjacent to each other on the same axis. In principle, this counter is suitable for accumulating and indicating the unit purchase volume or transmission volume of systems such as electricity, gas or water. Below, the focus is on the accumulation and indication of electric energy. In this case, the purchase of this type of energy unit is specifically explained. It is by no means to reduce the illustrated a...

Abstract

The invention relates to a unidirectional counter comprising a worm wheel (1), which can be driven, and at least one numeric indicator (3), which can be driven by the rotation of the worm wheel (1). Said wheel (1) cooperates with a system wheel (8) by means of a first system of ratchet teeth (6, 7a, b) comprising at least one first pair of equally acting ratchets (7a, b) which cooperate with each other. Moreover, a reversing wheel (10) can be driven by the worm wheel (1), wherein said reversing wheel (10) cooperates with a second system wheel (14) by means of a second system of ratchet teeth (12, 13a, b) comprising at least one second pair of equally acting ratchets (13a, b) which cooperate with each other. The invention aims to count and show the consumed units of energy as precisely as possible, even when there is a change in the direction of rotation. To this end, the transmission ratio between the worm wheel (1) and the reversing wheel (10) and / or between the first and second system wheels (8, 14) is different from 1, which compensates for the slower, system-inherent backwards rotation speed of the rotor disk arrangement in the unidirectional counter.

Description

Technical field [0001] The present invention relates to the technical field of counters, and more specifically, to a one-way counter, which may be driven in two directions to indicate a one-way direction. Background technique [0002] The one-way counter is designed to accumulate and indicate, for example, the total amount and / or consumption of water, gas or electric energy. The one-way counter is especially suitable for electric meters, especially for Femris meters in this field. In the following, the present invention focuses on the application of the one-way counter to the Ferraris meter, but this does not exclude the application in other aspects, such as the application in gas or water systems. [0003] In the Ferraris meter known per se, a turntable mechanism is driven by line voltage and current consumption, and then the counter is driven. Such a counter may include a well-known digital scroll wheel or digital disc or have a pointer that rotates in front of a fixed digital ...
