MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517062562 A) filed by Wawrzynski, Pawel P, Nowe, Poland, on July 1, for 'hypocycloidal mechanism.'
Inventor(s) include Wawrzynski, Pawel.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "The invention concerns a hypocycloidal mechanism comprising: a shaft (4); a large gear (7) rotatable around its centre and coupled to the shaft (4); a small gear (8) parallel to the large gear (7), rotatably mounted on an axle, passing eccentrically through the large gear (7); a cylinder (1) with a piston (2); a connecting rod (3), on one side connected to the piston (2) and on the other side connected rotatably to the small gear (8) so that the rotation of the large gear (7) and the small gear (8) is coupled to the reciprocating motion of the piston (2); at least one bearing-supported stationary part (6) in which the large gear (7) is rotatably mounted. The invention is characterized in that the stationary part (6) is an internally toothed annular part, the small gear (8) being externally toothed and meshed with the internal toothing (6') of the stationary part (6); the large gear (7) is externally toothed and is rotatably mounted in the stationary part (6) by means of a bearing (6"), so that the toothing (6') of the stationary part (6) extends over part of its thickness, and the stationary part has also an untoothed surface with the bearing support over a part of its thickness (6"), the large gear (7) has an untoothed surface complementary to the bearing (6") of the stationary part, the large gear (7) is coupled to the shaft (4) by means of its toothing (7"); the connecting rod (3) has two arms (3a, 3b) which extend at both sides of the gear assembly (7,8), where the first arm (3a) is connected to the small gear (8) at the first pivot point (O) on one side of the gear assembly (7,8), and the second arm (3b) is connected to the small gear (8) at a second pivot point (O') on the other side of the gear assembly (7,8), wherein the orthogonal projection of the first point (O) on the plane of the large gear (7) is at all times equal to the perpendicular projection of the second point (O') on the same plane of the large gear (7). The invention also concerns an engine and a compressor comprising such a mechanism."
The patent application was internationally filed on Mar. 18, 2024, under International application No.PCT/PL2024/050019.
