槽轮机构（又称马尔他机构）在实际生产和设计过程中，应用于各种自动机械中是很广泛的。它的特点是：构造简单、外形尺寸小、机械效率高，并能平稳地将主动轴均匀连续转动转换为从动轮的周期性间歇运动，其基本形式可分：外接、内接和球面槽轮三类。（图一）所示的普通外... Sheave mechanism (also known as Maltese institutions) in the actual production and design process, used in a variety of automatic machinery is very wide. Its features are: simple structure, small size, high mechanical efficiency, and can smooth a smooth continuous rotation of the drive shaft into a periodic intermittent movement of the driven wheel, the basic form can be divided: external, internal and spherical sheave Three categories. (Figure 1) as shown in the ordinary outer ...
