Abstract

本实用新型提供一种方便齿轮,该方便齿轮的两侧设有夹板,它能彻底地解决带有齿轮链条经常掉链的问题,如自行车等,如使用此方便齿轮后,可以使掉链的问题不再发生。

Description

方便齿轮
本实用新型涉及一种方便齿轮。
现有带链条的齿轮,都是两边没有夹板的齿轮。这种齿轮的缺点是链条易掉落。
鉴于现有齿轮的上述缺点,本实用新型的目的是提供一种新型方便齿轮,它在发挥现有齿轮同样作用的同时,可以使链条不易掉落,可以提高其运转的可靠性和安全系数。
为完成上述任务,本实用新型采用的方案如下:在传统齿轮的两侧增加两个夹板,两夹板的半径均大于齿轮的半径,使链条始终在两侧的夹板内运转,其中在主动轮夹板的一侧是可拆装的两个半圆。
本设计克服了原有齿轮的缺点,可避免链条掉落。
现结合附图作进一步说明。
图1为实施例的结构示图。
本实用新型涉及的这种方便齿轮,如自行车的齿轮两侧加有夹板1、3。图中5为链条。4为可拆装半圆的固定镙丝。

Claims (3)

1、一种方便齿轮,其特征是在齿轮的两侧加有夹板1、3。
2、根据权利要求1所述的方便齿轮,其特征在于:主动轮的夹板其中的一侧是可拆装的两个半圆。
3、根据权利要求1所述的方便齿轮,其特征在于:可拆装的两个半圆是用镙丝钉4来加以固定。
