Problems solved by technology

This leads to severe deformation of the matching hole between the driven transition gear and the support shaft in the gear set, resulting in inflexible rotation or jamming, and poor rotation accuracy, which affects the adjustment accuracy and adjustment efficiency.
In addition, the existing gear train and the mechanical counting wheel are also connected by gear transmission. The counting value can be implemented by directly adjusting the rotating counting wheel, and there is a hidden danger of artificial adjustment.

Abstract

The invention discloses a counter for a gas meter. The counter comprises a counter base and a counting wheel stand which are mutually clamped and fixedly connected with each other, and a counting wheel train comprising a change gear pair and a transition gear pair, wherein a driving change gear forms the input end of the wheel train; a driven change gear is tightly matched with a driving transition gear by virtue of a convex ring section formed in the middle of the driving transition gear; the driven change gear forms coaxial fixed connection by virtue of the driving transition gear and is rotationally matched with an internal section of a supporting shaft; the driving transition gear is positioned on an external section of the supporting shaft; a driven change gear limiting shaft shoulder is formed on the inner side of a matching section of the supporting shaft; a raised shoulder for preventing the driving transition gear from retreating is formed at the front end of the matching section of the supporting shaft; and the driven transition gear is connected with a first-stage counting wheel of the counting wheel group by virtue of worm-gears. The counter for the gas meter disclosed by the invention has the beneficial effects that the structure is simple, the counting wheel stand is convenient to mount and detach, the motion precision of the counting wheel train is high, the counter is accurate in counting, and hidden danger of manually adjusting the counting numerical value is avoided.

Description

technical field [0001] The patent of the present invention relates to a gas meter counter component, in particular to a gas meter counter. Background technique [0002] The measurement of gas consumption is realized by a gas meter. The gas meter includes a movement and a counter. The movement is arranged inside the watch case, and the counter is arranged outside the watch case. For the mechanical counter, the reciprocating swing of the inner bladder of the movement forms a rotary motion output through the conversion mechanism, and the mechanical counter drives the counting wheel to rotate through the gear transmission structure to realize the counting display. The gear transmission system of the counter is usually equipped with an exchange gear pair and a transition gear pair. The transition gear pair matches the rotary volume of the metering chamber. The exchange gear pair is used to adjust the gas meter by selecting different gear ratios and modulus. Exchange the gear pai...
