Title:
VARIABLE-SPEED SPEED-UP MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/195321
Kind Code:
A1
Abstract:
A variable-speed speed-up mechanism (1) is provided with a motorized apparatus (50) and a gearbox (10). In the gearbox (10), an inner-gear carrier shaft (37) forms a constant-speed input shaft (Ac), and a planetary-gear carrier shaft (27) forms a variable-speed input shaft (Av). The motorized apparatus (50) has: a constant-speed motor (51) that has a constant-speed rotor (52) for rotating the constant-speed input shaft (Ac); and a variable-speed motor (71) that has a variable-speed rotor (72) connected to the variable-speed input shaft (Av). The variable-speed speed-up gear (1) is further provided with a braking mechanism (200) that detects an abnormal state of the variable-speed motor (71), that stops rotation of at least one of the variable-speed input shaft (Av) and the variable-speed rotor (72), and that continues rotation of the constant-speed rotor (52).
