Document Type and Number:
WIPO Patent Application WO/2024/000871
Kind Code:
A1
Abstract:
A transmission system (1). The transmission system (1) comprises: a gearbox (10), comprising a box body (11), an output shaft (12) and a bearing (13), the output shaft (12) being rotatably connected to the box body (11) by means of the bearing (13); and a generator (20), comprising a rotor (21), a stator and a packaging assembly (22), wherein the stator is connected to the box body (11), the rotor (21) is connected to the output shaft (12), and the packaging assembly (22) comprises a sealing cover (221), a first connector (222) and a second connector (223), the sealing cover (221) being located on the same side of the output shaft (12) and the rotor (21), the sealing cover (221) being fixedly connected to the rotor (21) by means of the first connector (222) and being fixedly connected to the output shaft (12) by means of the second connector (223), the sealing cover (221) being insulated from the first connector (222) and the rotor (21), and the sealing cover (221) being insulated from the second connector (223) and the output shaft (12). Further provided is a wind power generating set. The transmission system can reduce the effect of shaft voltage on the bearing, and has a low cost.
