The quasi kinetics and load characteristics of Following Teeth Transmission(FTT)are researched all sidedly in accordance with its fundamental structure models.In the meantime the interactions of elastic deformations

manufacture errors

lubricating film and so on

are taken into consideration simulataneous of a number of teeth.According to the loading a centralized regressive loading formula is proposed.The concept about skidding coefficient of FTT is firstly introduced.Since there are local freedoms at the following rollers and the outer ring of eccentric bearing

the skidding states of FTT are brought to light.The conclusions were verified by the methods of photo elastic analysis and high speed photography was taken during authors′ experiments and the test results support the conclusions of the paper satisfactorily.
