Title: Takashi Niidome: Innovator in Wet Braking Technology

Introduction

Takashi Niidome is a prominent inventor based in Tsuchiura, Japan. He has made significant contributions to the field of engineering, particularly in the development of innovative braking systems. With a total of 4 patents to his name, Niidome's work has had a substantial impact on construction machinery.

Latest Patents

One of Niidome's latest patents is a wet brake device. This device features a plurality of rotating side brake disks and non-rotating side brake disks arranged radially from a motor shaft within a brake case. These disks overlap alternately, and a frictional material is applied to the non-rotating side brake disk. An oil groove is integrated into the frictional engaging surface of this material. When a braking force is applied by a brake piston to the motor shaft, lubricant oil flows into the brake case from an inlet port, moving from the outer diameter to the inner diameter through the oil groove. This design ensures that the lubricant oil efficiently cools the frictional engaging surface.

Another notable patent is for a revolving apparatus for construction machines. In this invention, an electric motor is positioned on a reduction device, with a wet braking device providing braking force to the motor shaft. The wet braking device includes a brake case that houses the upper end of the motor shaft, along with an adapter that can be detached from the motor shaft within the brake case. This system allows for the maintenance of the wet braking device without disassembling the electric motor from the reduction device.
