So what’s the deal with all these fidget spinners lately?
最近流行的指尖陀螺是什么样的玩具呢？
Every kid in the neighborhood seems to have one.
邻居家的孩子们似乎人人都有一个
To some, they’re a stress reliever, and to others, they are just a fun toy.
它可以缓解压力 或作为趣味性的玩具
You can spin them on the table.
你可以先在桌子上旋转它们
You can spin them while holding them.
在它们旋转的时候用手指托住
You can balance them while they spin.
在它们旋转时 你可以让陀螺保持稳定
You can even stack them on top of each other while they are spinning.
甚至在旋转的时候可以把它们叠在一起
A good fidget spinner will continue to spin for a while on its own.
优质的指尖陀螺还能够独自旋转一段时间
Fidget spinners are about three inches wide,
指尖陀螺大约有3英寸宽
and only a quarter inch thick.
仅0.25英寸厚
Let’s take one apart, and see what it looks like.
我们来观察一个拆开后的指尖陀螺
Each of the three weights here, are usually wedged in pretty tight.
内部有三块砝码 每块都被紧扣在陀螺中
They can be popped out just by pushing on them.
只需往前压一下就可以把它们取出
Some people like to switch these out for different weights.
有些玩家喜欢更换不同重量的砝码
If they are ever unbalanced, the fidget spinner won’t spin for very long.
如果重量不均衡 陀螺将无法旋转太久
The middle is where the magic happens.
陀螺的中间部位是这个玩具的奇迹之源
You’ve got two caps; one on the top and one on the bottom.
这里上下两端各有一个盖子
Use your fingernail or a flat tool to pry these off.
用指甲或扁平的工具把它们撬开后
Underneath is what they call the ball bearing.
可以看见里面的滚珠轴承
The whole point of the ball bearing is to reduce friction, so it can spin for longer and faster.
轴承的主要作用就是减少摩擦 让陀螺旋转得更迅速和长久
There are a few different parts here, the outer ring, the inner ring, the balls,
轴承由外圈 内圈 钢珠和保持器构成
and the cage to separate the balls.
保持器把这些钢珠分离开
When it’s spinning, the caps hold the inner ring in place.
旋转时 上下两端把内圈固定在适当位置
This part of the cap fits right inside the inner ring; the same with the bottom cap.
上盖与底盖中间的凸起正好被套在内圈中
So the caps don’t spin, which means the inner ring doesn’t spin.
所以上下盖不旋转就意味着内圈无法旋转
The outer ring spins along with the rest of the spinner.
而外圈可以随着陀螺其余部分一块旋转
The balls in the middle are what allows it to spin so well;
中间部分的钢球能令其旋转的更出色
they roll along as the outer ring spins.
它们随着外圈的旋转而滚动
You’ll notice grooves here on both the inner and outer rings which guide the balls.
你可以注意到内外圈的沟槽在引导着球的转动
The cage keeps the balls evenly spaced apart – which holds the inner ring in place.
保持器把钢珠均匀分开 从而内圈固定到位
And that’s how a Fidget Spinner works.
以上就是指尖陀螺的工作原理
