Hamster wheels are exercise toys used by hamsters and other rodents. Most of these toys are composed of a runged wheel held on a stand by a pair of stub axles. Hamster wheels allow rodents to run even when their space is confined.

Hamster wheel(倉鼠轉(zhuǎn)輪)是專供倉鼠及其他嚙齒類小動物消遣的玩具。這種轉(zhuǎn)輪大部分都是將一個橫梯式的轉(zhuǎn)輪用一對轉(zhuǎn)軸固定在一個底座上。有了這樣的倉鼠轉(zhuǎn)輪，小動物們就算在狹小的空間里也能跑動起來。

To hamster wheel something, in this sense, means to talk continuously about a problem or regret without coming up with a solution or resolution.

由此引申得出，to hamster wheel something(像倉鼠轉(zhuǎn)輪那樣說一件事)意思就是不斷重復某一個問題或者對某事表示遺憾，卻無任何成效，也就是我們平時說的“車轱轆話來回說”。

For example:

It’s not helpful that Jane keeps hamster wheeling about her latest break-up.

簡老跟人說她最近分手的事，其實一點用都沒有。
