Abstract
The utility model discloses a one-way clutch of a starter for an internal combustion engine, which comprises an input shaft sleeve (1) and a torsion output shaft component (2). The input shaft sleeve (1) is arranged on the torsion output shaft component (2), five troughs (6) are arranged on the internal ring of the input shaft sleeve (1), arranged in each of the troughs (6) are two abreast positioned rollers (3) and two flat springs (4) correspondingly supporting the rollers, the contact surfaces of the rollers (3) and the troughs (6) are Archimedes inward curved surfaces, and a position-limiting clipping plate and a cover (5) are arranged on the input shaft sleeve (1). To integrally connect the two abreast positioned flat springs (4) by one side of each of the flat springs, steel wires (7) are connected with the end faces of one side or two sides between the flat springs (4). After applying the structure, the utility model resolves the problem of early dysfunction caused by the easy breaking of the joint of blocks, such as special washers, or easy overlapping of the two flat springs. The utility model has the advantages of compact and reasonable structure, life service life, great transmission torsion, convenient production and processing, etc.
Description
Technical field
The utility model relates to a kind of clutch, the starter motor overrunning clutch that uses on particularly a kind of internal-combustion engine.
Background technique
Fast development along with domestic automobile industry, with the diesel engine is that demands such as vehicle powered, engineering machinery, generator set grow with each passing day, also increasing with the matching used starter motor overrunning clutch of internal-combustion engine demand, requirement to starter motor overrunning clutch endurance test number of times is also more and more higher, to output power require increasing.As new industry standard JB/T6707-2006 regulation, the endurance test number of times is 10000 times, and original industry standard JB/T6707-93 endurance test number of times is 8000 times, and the structure of originally single roller and single flat spring can not satisfy the requirement of output power.In order to adapt to the new standard and the market demand, we once adopted following structure: the one, and two rollers placed side by side and two correspondences are supported on the flat spring structure on the roller in groove, after testing, dissect and find, juxtaposition has been together to be seated in two flat springs in the groove side by side, one of them roller supports because of no flat spring, can not be close to Archimedes's negative camber and cause overrunning clutch to lose efficacy, test number (TN) generally two flat spring juxtapositions just occur at 3000 to 5000 times and causes the overrunning clutch failure phenomenon.The 2nd, overlapping in order to prevent flat spring, in the middle of two rollers placed side by side and two corresponding flat springs, install extraordinary packing ring additional, find that through test fracture appears in the piecemeal joints such as extraordinary packing ring between two rollers, the fragment of fracture makes roller and the wedging of negative camber contacting point stuck in die cavity, cause overrunning clutch to lose efficacy, test number (TN) generally extraordinary packing ring fracture just occurs at 3000 to 5000 times and causes the overrunning clutch failure phenomenon.For this reason, develop that a kind of long service life, transmitting torque are big, production and processing easily overrunning clutch be extremely urgent problem.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing overrunning clutch exists, problem to be solved in the utility model provide a kind of simple and compact for structure, access times are many, transmitting torque is big, production and processing starter for internal combustion engine overrunning clutch easily.
The technological scheme that its technical problem that solves the utility model adopts, it comprises input axle sleeve, torque output shaft assembly, the input shaft cover is set on the output shaft assembly, described input axle sleeve inner ring is provided with five grooves, be provided with two rollers placed side by side and corresponding two flat springs that are supported on the roller in each groove, the surface of contact of roller and groove is Archimedes's negative camber, puts at input shaft and is provided with stop bit card and cover cap.
Side end face between described two flat springs placed side by side is connected with steel wire, and a side of two flat springs is connected as a single entity.Perhaps the both sides end face between two flat springs placed side by side is connected with steel wire, and the both sides of two flat springs are connected as a single entity.
After adopting said structure, be provided with two rollers placed side by side and corresponding two flat springs that are supported on the roller in each groove, side end face between two flat springs placed side by side or both sides end face connect steel wire, two flat springs are connected as a single entity, reach 13000 times through the starter motor test endurance test number of times of packing into, chucking, the failure phenomenon of skidding had not occurred; This structure has not only solved the easily overlapping problem that causes overrunning clutch early failue of two flat springs, and has solved piecemeal joint frangibility such as extraordinary packing ring, problem that cost is high; Have advantages such as compact structure is reasonable, long service life, transmitting torque is big, production and processing is convenient.
