REVOLUTION INTRODUCING MECHANISM FOR SEALED CONTAINER

摘要

PURPOSE:To prevent the deflection of revolution ratio and generation of breakage by using an inscribed gear mechanism between an internal gear and an external gear for introducing a turning power into a sealed container and permitting the revolution movement of one gear around another gear. CONSTITUTION:The first rotary shaft 15 and the second rotary shaft 17 are rotatably accommodated into a sealed container 10, and at the edge part of the second rotary shaft 17, a counterweight 19 is installed on one edge side and a crank 20 is installed on the other. Further, an internal gear 21 is installed onto the crank pin 20B of the crank 20 through a needle bearing 22. While, an external gear 23 is installed integrally onto the first rotary shaft 15. Therefore, the internal gear 21 performs revolution motion around the external gear 23, and since the transmission of revolution is carried out certainly with the revolution ratio determined according to the number of teeth, the deflection of revolution ratio, breakage of each part due to slide, and the difficulty in assembly work can be eliminated.
