Title:
REDUCTION GEAR
Document Type and Number:
WIPO Patent Application WO/2020/144411
Kind Code:
A3
Abstract:
Disclosed is a mechanical reduction gear (5) comprising a rotor (32), an outer ring gear (55) of pitch diameter D55, a planet carrier (57), which comprises at least one planet gear (51, 52, 53, 51', 52') of pitch diameter D50 designed to rotate inside the ring gear with an eccentricity of value "e" equal to half the difference between the diameter D55 and the diameter D50; e = ½(D55 - D50); the at least one planet gear being mounted so as to be able to rotate on the rotor (32) by means of an eccentric (315, 316, 317) comprising at least one cam (3101, 3102, 3171, 3172); the cam comprising an inner surface (31012, 31022, 31712, 31722) that is cylindrical of diameter D31 and an outer surface (31013, 31023, 31713, 31723) that is cylindrical of diameter D504, the diameter D504 being equal to the sum of the diameter D30 and double the eccentricity "e"; D504 = D31 + 2e.
