JIGSAW WITH RECIPROCATING SAW BLADE Russian patent published in 2023 - IPC B27B19/02 B23D49/16 

FIELD: jigsaws.

SUBSTANCE: jigsaw includes a body, a drive, a bevel gear, a rod and a hacksaw blade. The input and output shafts are coaxially installed in the actuator housing. A fixed elliptical gear is rigidly fixed to the housing coaxially with the input shaft, and another elliptical gear is mounted on the output shaft. A carrier is installed on the input shaft, made in the form of a bevel pinion, meshed with a bevel gear, and connected through a rotational kinematic pair to the satellite shaft. The satellite consists of an elliptical gear and an elliptical gear rotated 180° relative to each other and connected by a shaft, and the elliptical gear of the satellite is connected to a stationary elliptical gear of the same size, and the elliptical gear of the satellite is in gearing with an elliptical gear of the same size. A gear sector is rigidly fixed to the output shaft, connected by a gear transmission to a rod, the central part of which is made in the form of a gear rack, while the rod is located in guides fixed in the body of the jigsaw.

EFFECT: reliability and efficiency of the jigsaw drive increases.
