Title:
CLUTCH AND DRIVE DEVICE HAVING THE CLUTCH
Document Type and Number:
WIPO Patent Application WO/2000/008349
Kind Code:
A1
Abstract:
A clutch, comprising drivingly rotating bodies (11; 52; 83; 202; 302) connected to a drive source (2) such as a motor and drivenly rotating bodies (12; 53; 85; 204; 303) engaged directly with the drivingly rotating bodies, wherein both rotating bodies are stored in housings (13; 51; 82; 201; 301), lock members (14; 54; 86; 119; 205; 304) comprising rollers and balls are disposed between the drivenly rotating bodies and the housings, when the drivenly rotating bodies themselves are rotated, the lock members are held between the drivenly rotating bodies and housings so that a rotation of the drivenly rotating bodies relative to the housings is prevented, when the drive source rotates the drivingly rotating bodies, the lock members reset the holding condition so as to allow the drivingly rotating bodies to rotate the drivenly rotating bodies relative to the housings, whereby the clutch can prevent securely a transmission of rotation from the drivenly rotating bodies to the drivingly rotating bodies and, in addition, strengths required for both rotating bodies can be reduced.
