Chain-type gear crown for transmission gear wheels has segments combined into single effective component by toothed chain round them

摘要

The chain-type gear crown consists of links (1, 2), which can rotate relative to each other on axis couplings (7), and which pass round the segments of the transmission gear wheel, combining it into a single effective component. The gear crown links are so shaped that they engage in the links of the transmission chain and form a circle round the segmented gear wheel.
