Multimedia technology used in teaching not only can facilitate the reform of educational modal, also can accelerate the renovation of teaching materials, teaching method and class teaching structure in the field of higher education.
Multimedia not only impinges on individual learning, but also on the many functions of the higher education sector: teaching, development of teaching materials and pedagogies, teacher training, assessment of students and accreditation of course material.
At present, a vast and rapidly increasing amount of educational material is becoming available over the Internet, and an increasing number of traditional providers of educational support material are moving into the WWW.

The expression of the contact stiffness is: (3) (4) (5) Where μ1, μ2 is respectively the Poisson’s ration of the materials of the two gears, E1, E2 is respectively the Young’s modulus of the materials of the two gears, R1, R2 is respectively the equivalent radius of the contact point of the two gears(“+” expresses outer teething, “-” expresses internal teething).
The material of the planet gears is 20CrMnTi of which Poisson’s ration is 0.28 and the Young’s modulus is 2.07×105Mpa.
