Meshing gears transfer motion between parts as a central play feature.
What it is
Gear Linkage uses meshing gears to transfer motion between parts, so turning or sliding one part drives another. In EDC, the gears are the main play feature: you see and feel the teeth engage as the parts move together. Gear count, size and ratio depend on the brand.
How it feels in your EDC
You feel a smooth, interlocked motion, often with a subtle texture as each tooth meets the next. Watching linked parts turn together is part of the appeal. Gear ratio changes how fast parts move relative to each other, so some designs feel quick and light while others feel slow and deliberate.
What to look for
Check whether the gears are visible and what they are made of, since material affects smoothness, sound and wear. Look for even, wobble-free engagement. Keep grit out of the teeth, and follow the brand’s advice before adding any lubricant.
是什么
齿轮联动（Gear Linkage）利用相互啮合的齿轮在零件之间传递运动，转动或滑动一个零件就能带动另一个。在 EDC 中，齿轮本身就是主要的玩点：零件一起运动时，你能看到并感受到齿与齿的啮合。齿轮数量、尺寸和传动比取决于品牌。
上手感受
你会感受到顺滑、环环相扣的运动，每个齿相遇时常带着细微的质感。看着联动的零件一起转动，本身就是乐趣之一。传动比决定零件之间的相对速度，有的设计轻快，有的则缓慢从容。
选购要点
确认齿轮是否外露以及材质，材质会影响顺滑度、声音和磨损。看啮合是否均匀、没有晃动。避免砂粒进入齿间，添加润滑剂前请遵循品牌建议。
