Abstract

The invention includes at least two free disks arranged between a drive-torque transmission disk and an output-torque receiving disk, each of the at least two free disks being freely rotatable. When a torque is to be transmitted, mutual gaps between the drive-torque transmission disk, the at least two free disks and the output-torque receiving disk are narrowed, so that the input torque of the driving unit is transmitted from the drive-torque transmission disk to one free disk adjacent to the drive-torque transmission disk by friction, the torque transmitted to the one free disk is transmitted to another free disk adjacent to the one free disk by friction, and the torque transmitted to the or another free disk on the most output-shaft side is transmitted to the output-torque receiving disk by friction.

Abstract

A multiple free disc-type clutch is provided with at least two free discs each disposed in a freely rotatable manner between a drive torque-transmitting disc and an output torque-receiving disc. When the multiple free disc-type clutch transmits torque, the distance between the drive torque-transmitting disc, the at least two free discs, and the output torque-receiving disc is reduced, input torque from a drive device is transmitted by friction from the drive torque-transmitting disc to a free disc adjacent to the drive torque-transmitting disc, the torque transmitted to the free disc is transmitted by friction to a free disc adjacent to the free disc, and the torque transmitted to the free disc located closest to the output shaft side is transmitted by friction to the output torque-receiving disc.

Abstract

A floating-disk type brake system that includes floating disk assemblies placed respectively in spaces between a rotating member, such as a wheel of a transportation machine or a rotating shaft of a machine tool, and a stationary member to reduce differences in the rotating speed of adjacent sliding surfaces of the floating disk assemblies in frictional sliding engagement. The floating-disk type brake system includes a first floating disk assembly and a first disk assembly that are arranged between the ring gear and the planet carrier of a planetary gear built in a transmission or the like, and the first floating disk assembly and the first disk assembly are pressed together into frictional engagement to brake a rotating shaft.

Abstract

A freely rotating annular body type brake device, wherein the rotational speed of a rotating portion such as the wheel of a means of communication and the rotating shaft of a machine tool relative to that of a stationary portion at their frictional sliding portions is reduced by interposing a freely rotating annular body between the rotating portion and the stationary portion to increase a braking force while reducing a heating value due to braking. A first freely rotating annular body (50) and a second annular body (60) are interposed between a ring gear (35) and a planetary carrier (32) built in a transmission, and pushed by a pushing means (70) for frictional engagement. As a result, the freely rotating annular body type brake device capable of braking the rotation of a rotating shaft (23) can be provided.
