Title:
SAW USING ELLIPTICAL INTERNAL GEAR
Document Type and Number:
WIPO Patent Application WO/2021/256575
Kind Code:
A1
Abstract:
The present invention relates to a saw using an elliptical internal gear, wherein one-way rotational force of a power source is converted into linear reciprocating transfer force by a pinion gear engaged along a pitch circle of the elliptical internal gear, so as to output forward and backward cutting force of a saw blade at a constant speed such that sawing work is stably performed. In particular, in order to simplify components and extend a forward-and-backward cutting stroke distance of the saw blade in a lightweight and compact structure, the saw using an elliptical internal gear comprises, as main components: a planetary gear assembly (10); an internal gear assembly (20); and a linear rod part (30).
