Overrunning coupler

Abstract

The invention discloses an overrunning coupler comprising a shaft. The periphery of the shaft is provided with an outer hub, the right end of the shaft is provided with a screw, a nut is arranged between the screw and the shaft, and an oscillating bar is arranged the lower part of the nut; the center of the outer hub is provided with a star wheel in which a circular-arc torsional spring is arranged; a retainer and six pin rollers are evenly arranged between the outer hub and the star wheel, the outer circle of the retainer forms an outer ring, and the inner circle of the retainer forms an inner ring; the upper end of the star wheel is provided with a dust cover of which the inner end surface is provided with a teething ring; the inner retainer, the outer retainer and a plurality of fixture blocks are evenly arranged between the inner ring and the outer ring; a plurality of springs are evenly arranged between the inner retainer and the outer retainer; fixed reeds are evenly arranged between the outer retainer and the outer ring; and a friction reed is arranged between the inner retainer and the inner ring. The overrunning coupler of the invention has the advantages of automatically overrunning the clutch, being capable of stopping overrunning, saving energy consumption, lowering driven system abrasion, having flexible response and not slipping.

Description

Technical field: [0001] The invention relates to an overrunning clutch. Background technique: [0002] Overrunning clutches are widely used in aircraft, tanks, military trucks, off-road vehicles, loaders, forklifts, automobiles, motorcycles, bicycles, lathes, printing machinery, textile machinery, nut forming machines, gap transmission mechanisms of automatic production lines, mining machinery, wrenches etc., the traditional overrunning clutch is realized by a manual serial gear combination mechanism. During work, manual operation is frequent, which is not suitable for realization. The transmission system is severely worn, and the energy consumption is high. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide an overrunning clutch that can realize automatic overrunning clutch, stop overrunning, save energy consumption, reduce wear of transmission system, and is sensitive in response and does not slip.

[0002] Overrunning clutches are widely used in aircraft, tanks, military trucks, off-road vehicles, loaders, forklifts, automobiles, motorcycles, bicycles, lathes, printing machinery, textile machinery, nut forming machines, gap transmission mechanisms of automatic production lines, mining machinery, wrenches etc., the traditional overrunning clutch is realized by a manual serial gear combination mechanism. During operation, manual operation is frequent, which is not suitable for realization. The transmission system is severely worn and energy-consuming. When overtaking, the clutch is slow to respond and slips.
