凸轮从动滚轮的英文 凸轮从动滚轮用英语怎么说

"凸轮从动滚轮" can be translated as "cam follower roller" in English.

Here, "凸轮" (tū lún) means "cam," "从动" (cóng dòng) means "follower" (in the context of a mechanical system where one part follows the motion of another), and "滚轮" (gǔn lún) means "roller." Combining these terms, we get "cam follower roller," which accurately describes the component in mechanical engineering.
