Rack tooth sprocket

a kind of new transmission mechanism has the characteristics of common sprockets and the advantages such as more stable transmission

higher precision and simpler manufacture.According to the production batch size

the sprocket can be manufactured by forming milling and generating hobbing

and the generating hob can be designed by the theory of gear meshing.Although there are less application cases or related documents about the transmission domestically

it could be widely used in the future.The kinematics and dynamics of rack tooth sprockets transmission are analyzed

the formula of its tooth form is given

and then the hob tooth can be designed accordingly.It is verified that the sprockets run well with chains and perform stably.
