摘要： A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided on the non-rotating side brake disk, and an oil groove is provided in a frictional engaging surface of this frictional material. It is configured such that, when a braking force is applied by a brake piston to the motor shaft, lubricant oil flowing into the brake case from a lubricant oil inlet port flows from the outer diameter side to the inner diameter side between the rotating side brake disk and the non-rotating side brake disk only through the oil groove. As a result, the lubricant oil having flowed into the brake case efficiently cools the frictional engaging surface.

摘要： An electric motor is arranged on a reduction device, and a wet braking device which gives braking force to a motor shaft is arranged on an upper end side of the electric motor. The wet braking device has a brake case which accommodates an upper end portion of the motor shaft, an adapter which is detachably disposed to the motor shaft in the brake case, a plurality of rotating side brake disks and a plurality of non-rotating side brake disks arranged on an outer peripheral side of the adapter and a brake piston which gives braking force to the motor shaft by frictionally engaging the rotating side brake disks and the non-rotating side brake disks with each other. At the time of performing a maintenance operation for the wet braking device, the wet braking device alone can be solely removed while keeping the electric motor assembled to the reduction device.

摘要： A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided only on the non-rotating side brake disk in these rotating side brake disk and the non-rotating side brake disk. As a result, the weight of the rotating side brake disk can be reduced, and drag resistance of the rotating side brake disk rotating also in brake release can be reduced.
