CENTRIFUGAL CLUTCH (VERSIONS), DRIVE UNIT (VERSIONS) AND METHOD OF MOUNTING OF DRIVE UNIT Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: clutch and drive unit can be used for connecting drive shaft with driven member. Centrifugal clutch for connecting drive shaft with driven member at speeds rotation exceeding the limited determined before, has centrifugal sliding loc with massive thickening at one end and first connecting basis, bracket made for rest of centrifugal sliding lock against additional formations to restrict its movement of sliding between extended radial position and removed radial position and for tight fitting onto drive shaft to drive it into motion, output drive member mounted for free rotation onto drive shaft. Output drive member is intended for clutching with driven member and is provided with second connecting formation connected in such a way to provide drive with first connecting formation only at extended position of centrifugal sliding lock. There is also aid which is full-sized located inside groove of centrifugal sliding lock for shifting centrifugal sliding lock to its removed position. As a result, rotation of centrifugal sliding lock and bracket makes massive thickening pushing centrifugal sliding lock to radial direction from its removed radial position to its extended radial position. In this case first and second connecting formations clutch to each other and as result to transmit rotation movement from drive shaft to driven member. Aid for shifting centrifugal sliding lock is adapted to initiate uncoupling of first and second connecting formations when rotation of centrifugal sliding lock and bracket stops and drive shaft disconnects from driven member.

EFFECT: reduced number of items; simplicity of mounting, reduced cost.
