Description

一种双向计数器
技术领域
本实用新型涉及一种流量计用指示装置，尤其是能对正向和反向机械转动均能增计数的双向计数器。
背景技术
目前，流量计配置的计数器为单向计数方式，即当流量计按规定的流向工作时，计数器增计数，当与规定的流向相反时，计数器减计数；或者与之相反，即流量计按规定的流向工作时，减计数，与规定流向相反时，增计数。这样，当用户由于某种需要将已配置的流量计的流向反向工作时，这时存在计数器不能满足要求，而需要更换一台流量计才能实现，给用户及流量计制造商带来很大的不方便和时间、经济上的损失。中国专利 CN200620104606.0 公开了一种燃气表双向计数器，中国专利 CN200520012164.2 也公开了一种燃气表双向计数器，这两个专利都是采用正转齿轮系和反转齿轮系两套齿轮传动的方式实现计数器的输入轴向同一方向转动，进而达到计数器增数的目的。虽然解决了单向增计数反向减计数的问题，但其结构复杂、成本高，不适于推广应用。
实用新型内容
为了克服现有的双向计数器结构复杂、成本高的不足，本实用新型提供一种双向计数器，该双向计数器实现双向增计数的同时结构简单、成本低。
本实用新型的技术方案是：一种双向计数器 包括中心齿轮、驱动轴、字轮及主轴，驱动轴通过传动机构带动字轮转动，主轴的一端与介质驱动的中心齿轮相连并由中心齿轮带动转动，主轴的另一端连接有主锥齿轮，驱动轴上安装有相对的左锥齿轮和右锥齿轮，左锥齿轮与驱动轴之间以及右锥齿轮与驱动轴之间分别安装有同方向的单向轴承，主锥齿轮与左锥齿轮和右锥齿轮同时啮合。
所述的单向轴承为单向滚针轴承 。
所述的驱动轴与字轮之间通过齿轮传动。
所述的主锥齿轮与左锥齿轮及右锥齿轮之间的传动比相等。
所述的驱动轴上安装有限位套，所述的限位套位于左锥齿轮及右锥齿轮的外侧。
本实用新型具有如下有益效果：由于采取上述方案， 介质流动驱动中心齿轮转动，进而使主锥齿轮转动，由于左锥齿轮和右锥齿轮同轴设置在驱动轴上，左锥齿轮和右锥齿轮的转向相反，使左锥齿轮和右锥齿轮中的一个通过单向轴承带动驱动轴正向转动，而另一个空转，不对驱动轴产生负方向的力矩；介质流动方向相反时，中心齿轮反转，主锥齿轮也反转，仍然使左锥齿轮和右锥齿轮中的一个通过单向轴承带动驱动轴正向转动，而另一个空转。因此，不管介质流向是正向还是反向，由于单向轴承只按一个方向旋转，主锥齿轮始终带动驱动轴按同一方向转动，实现了双向增计数或双向减计数，与背景技术相比较结构简单，成本低 。
附图 说明
附图 1是本实用新型的结构示意图。
附图 2是图 1 的左视图。

具体实施方式
下面结合附图对本实用新型作进一步说明：
由图1结合图2所示，一种双向计数器包括中心齿轮1、驱动轴2、字轮3及主轴4，驱动轴2通过传动机构带动字轮3转动，主轴4的一端与介质驱动的中心齿轮1相连并由中心齿轮1带动转动，主轴4的另一端连接有主锥齿轮5，驱动轴2上安装有相对的左锥齿轮6和右锥齿轮7，左锥齿轮6与驱动轴2之间以及右锥齿轮7与驱动轴2之间分别安装有同方向的单向轴承8，主锥齿轮5与左锥齿轮6和右锥齿轮7同时啮合。由于采取上述技术方案，介质流动驱动中心齿轮1转动，进而使主锥齿轮5转动，由于左锥齿轮6和右锥齿轮7同轴设置在驱动轴2上，左锥齿轮6和右锥齿轮7的转向相反，使左锥齿轮6和右锥齿轮7中的一个通过单向轴承8带动驱动轴2正向转动，而另一个空转，不对驱动轴2产生负方向的力矩；介质流动方向相反时，中心齿轮1反转，主锥齿轮5也反转，仍然使左锥齿轮6和右锥齿轮7中的一个通过单向轴承8带动驱动轴2正向转动，而另一个空转。因此，不管介质流向是正向还是反向，由于单向轴承8只按一个方向旋转，主锥齿轮5始终带动驱动轴2按同一方向转动，实现了双向增计数或双向减计数，与背景技术相比较结构简单，成本低。
由图1所示，所述的单向轴承8为单向滚针轴承。单向轴承8采用单向滚针轴承结构紧凑，占用空间小。
由图1所示，所述的驱动轴2与字轮3之间通过齿轮传动。传动精确，计数准。
由图1所示，所述的主锥齿轮5与左锥齿轮6及右锥齿轮7之间的传动比相等。介质流向是正向和反向的计量相同。
由图1所示，所述的驱动轴2上安装有限位套9，所述的限位套9位于左锥齿轮6及右锥齿轮7的外侧。限位套9限定左锥齿轮6及右锥齿轮7的位置，以便左锥齿轮6及右锥齿轮7能够与主锥齿轮5正确啮合，避免左锥齿轮6及右锥齿轮7窜位。
