GEAR DEVICE FOR ROTARY CONNECTION OF WIND POWER GENERATOR, WIND POWER GENERATOR HAVING THE GEAR DEVICE, AND SEAL ELEMENT FOR GEAR DEVICE

摘要

A gear device with improved lubrication characteristics and performance for retaining a lubricant is provided. Reduces wear on the central tooth of the gearing. In particular, the present invention relates to a gear device (1) for a rotary connecting portion (112a, 112b) of a wind power generator (100), and engages with a first gear (3) and a first gear (3). The second gear (5) in the state, and at this time, in the engaged position, the first tooth (11a) and the second tooth (11b) of the first gear (3) and the second gear (5). A gap space (17) is formed between the first tooth (9a) of the first and second teeth (9a), and further includes a seal element (7). The seal element (7) is a gap space against lubricant leakage. (17) is sealed. [Selection] Figure 4
