Composition

Cycloidal gear reducer on the input shaft is equipped with a displacement of 180 ° double eccentric sleeve, turn on the eccentric sleeve is equipped with two known as the arm of roller bearing, the formation of H, two cycloid gear center hole is the eccentric sleeve on the turning arm bearing raceway, and by a group of cycloid gear and pin gear mesh circular permutation needle, to form tooth difference, for the internal meshing gear reducer is institutions (in order to reduce friction, in small ratio of speed reducer, the needle with needle teeth on the gear set).
