要約
(EN)

A dry brake provided between a motor and a speed reducer and including a brake mechanism for applying a brake to a motor shaft and a brake housing surrounding a brake chamber housing the brake mechanism. The brake housing includes a partition wall that partitions a speed reducer chamber from the brake chamber when penetrated by the motor shaft. The partition wall includes a shaft sealing mechanism that limits a flow of a lubricating oil between the partition wall and the motor shaft, and an air passage that allows air to flow between the speed reducer chamber and the brake chamber while limiting an inflow of the lubricating oil into the brake chamber from the speed reducer chamber. An air breather for opening the interior of the brake chamber to the atmosphere is formed in the brake.
