摘要： A brake structure of a traction machine includes a brake drum which is made rotatable about a shaft disposed on a rotary axis of the traction machine, and an electromagnetic brake unit built in an inner space of the brake drum. The electromagnetic brake unit includes a plurality of movable iron cores, a plurality of brake shoes located on the outside of the individual movable iron cores and joined thereto by connecting members, the brake shoes having curved outer surfaces facing a curved inner surface of the brake drum, and a one-piece formed stationary iron core block. The one-piece formed stationary iron core block has a plurality of stationary iron core portions joined to the individual movable iron cores via compression springs for forcing the individual brake shoes against the curved inner surface of the brake drum via the movable iron cores and the connecting members.

摘要： A rotational machine includes a shaft, a rotary member rotatably mounted on the shaft with a bearing fitted between the shaft and the rotary member, an oil seal for sealing the bearing to prevent leakage of lubricant from inside the bearing through its axial end onto a surface of the rotary member, a brake which comes into sliding contact with a contact surface area formed on the surface of the rotary member for arresting rotation of the rotary member, a supporting member fixedly mounted on the shaft face to face with the rotary member forming a gap therebetween, the gap serving as a fluid path through which the lubricant which has leaked over the oil seal is allowed to flow, and an oil stop portion formed at a location in the gap between the oil seal and the contact surface area for impeding flow of the leaked lubricant.
