MULTI-SPINDLE NUT RUNNER Russian patent published in 2009 - IPC B25B21/00 B23P19/06 

FIELD: mechanics.

SUBSTANCE: multi-spindle nut runner incorporates a casing housing a motor coupled with a clutch with holders, one being fitted on the input shaft while the other one reciprocates on the output shaft. The proposed nut runner incorporates the mechanisms of intermittent action, spindles and chucks, planetary reduction gear, primary differential mechanism, additional differential mechanisms and reduction gears coupled with the said differential mechanisms. Intermittent action mechanisms are coupled with additional differential mechanisms, on the one side, and, on the other side, with the primary differential mechanism. The total number of differential mechanism makes n-1, where n is the total number of spindles, reduction gears and intermittent action mechanisms.

EFFECT: expanded performances.
