1·Can be a passive CAM or a spring-loaded device with two or more camming pieces on a stem.

可以是被动凸轮保护器，也可以是有两个或更多凸轮装置的弹簧保护装置。

2·The print head assembly can be pivoted from the printing position to a cleaning position by changing the positions of pins in a pair of camming slots.

印刷头组件可以通过改变销钉在一对凸轮型凹口内的位置而从印刷位置枢转到清洗位置。

3·This short article will explain how this shape works in the context of a camming device, and will explain the mathematical equation that defines the profile.

本文将解释这种形状的剖面如何在攀登用凸轮上发挥作用，以及采用这种剖面的数学依据。
