The intermittent motion mechanism is mostly existing defect

such as large impact and short down time.A new kind of multi-equal arc planet gear intermittent mechanism is proposed.On the basis of researching its constitution and operation principle

the motion law under six kinds of condition in a period is found and the corresponding mathematical model is established

the relation curve of each motion parameters following the change of active solar wheel corners are given.The research of stationary test

systematically discussion and optimization of the parameters are carried out.Compared with the sheave

the average angular acceleration is reduced to 1.35rad/s2 by 5.41rad/s2.The nonstationary property in motor processes of intermittent motion mechanism is effectively solved

the largest idle time is up to 120°

the practical value is obvious.
