Cycloid gears are not all the same.
Cycloid gears can be broadly classified into pin gear types and solid gear (CDC) types depending on their structure. They differ not only in their characteristics but also in their appearance.
The pin gear type features a structure in which pins are arranged for each tooth profile. Although it consists of a relatively large number of components, it offers excellent durability against torsional loads, impact loads, and repeated loading.
In contrast, the solid gear (CDC) type operates with an integrated structure in which the external and internal gears mesh with each other. Its simple structure results in fewer components and superior ease of assembly, while reduced friction losses provide excellent backdrivability.
Accordingly, pin gear types are suitable for environments where durability is critical, whereas solid gear (CDC) types are well suited for applications requiring efficiency and backdrivability.
Cycloid gear types are selected based on application requirements. Discover the characteristics of each type in more detail through this video.
