The external star wheel type overrunning clutch for loader has the characteristics of reasonable structure, can enhancetorque bearing force, and prolongs the service span.
Description
Technical field
The utility model relates to a kind of clutch that is applied to automobile, engineering construction locomotive even flowing moment of torsion, especially the loader free wheel device of transmission of power moment of torsion.
Background technique
The domestic star-wheel formula free wheel device that is applied at present on loader two axle assemblies has two kinds: a kind of is tradition band isolating frame star-wheel formula free wheel device, its main structure is made of middle input block and outer ring gear, star-wheel formula raceway on input gear, interior ring cam and the interior ring cam in the middle of middle input block comprises; Be inserted in isolating frame on the interior ring cam external diameter, roller is loaded into the interior and spring of packing into of roller slot on the isolating frame circumference on the position of gland regulation, spring promotion isolating frame and roller pretension are between the interior raceway and star-wheel plane raceway of outer ring gear, and the frictional force that linear differential produced of inner outer raceway drives roller and realizes locking and separating.Its deficiency, isolating frame is a thin-wall part, manufacturability is relatively poor, yielding, and branches such as the roller slot on the isolating frame require high, and the end face upper spring seat requires high to roller slot center contact ratio, machining accuracy is difficult to guarantee, therefore pretension is on raceway synchronously to make roller, and roller unbalance stress between inside and outside raceway is asynchronous, and roller weares and teares inhomogeneous during work, thereby cause roller surface on the star-wheel successively to be worn and torn and aggravate the damage of isolating frame, finally cause two axle assemblies to lose efficacy.
Another kind is a knock pin type star-wheel free wheel device, this structure cancellation isolating frame and gland and change the ejector pin that on each raceway sidewall of star-wheel, increases the band pressure spring into, with single each roller of pretension to list, the work synchronism is good, this clutch has solved the former difficulty of processing, and usability is improved; Outside its deficiency be: in frequent clutch work, roller often impacts ejector pin, and oil can not in time discharge in the knock hole, causes the ejector pin end face very easily to wear and tear; Again be exactly the spring eye on the star-wheel and the cooperation of ejector pin be sliding fit, excessive gap can not be arranged, if loading machine gearbox is oily dirty, in the receiving hole that just is easy to bring the carbon slag in the oil and foul into ejector pin, and be not easy out, increase severely so day by day, finally caused ejector pin to be pushed and block by the carbon slag, thus make each roller effectively pretension between two raceways, cause two inefficacies.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of more reasonable structure is provided, and strengthens moment of torsion strength, the external star-wheel type overrunning clutch for loading machine that increases the service life.
The purpose of this utility model is finished by technological scheme, it mainly is made up of middle input assembly, outer ring gear and little assembly, input assembly is made of middle input shaft and interior ring in the middle of described, tightens together with screw bolt and nut in the hole of ring in middle input shaft is sleeved on.
Described little assembly is made of outer ring, isolating frame, roller, M shape flat spring and overlaps in the inner chamber that fits over outer ring gear.
Described outer ring is provided with ring raceway, and a plurality of rollers are installed in raceway, and the isolating frame made from special material separates roller, and disposes M shape flat spring in single mode to list; The outer ring gear that described cover is furnished with little assembly is contained on the middle input assembly by two bearing housings.
The utility model compared with prior art has more reasonable structure, can strengthen the moment of torsion strength, and characteristics such as increase the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a little assembly structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly is made up of middle input assembly, outer ring gear and little assembly, input assembly is made of middle input shaft 5 and interior ring 3 in the middle of described, tightens together with bolt 4 and nut 6 in the hole of ring 3 in middle input shaft 5 is sleeved on.
Shown in Figure 2, little assembly described in the utility model is made of outer ring 8, isolating frame 10, roller 9, M shape flat spring 7 and overlaps in the inner chamber that fits over outer ring gear 1.Described outer ring 8 is provided with ring raceway, and a plurality of rollers 9 are installed in raceway, and the front and back of each roller 9 join respectively and are mounted with at least one isolating frame 10 and a M shape flat spring 7; The outer ring gear 1 that described cover is furnished with little assembly is sleeved on the middle input assembly by two bearings 11,12.
The utility model is input assembly and outer ring gear and do engagement running counterclockwise in the middle of exterior power imports into respectively, at middle input assembly than outer ring gear rotating speed height, roller is in raceway face idle running and surmounts state, the power of outer ring gear can't import into, power directly imports into and exports from middle input assembly, when middle input assembly rotating speed is lower than the outer ring gear rotating speed, roller is in the raceway face frictional rotation and wedging, input assembly and outer ring gear rotate together in the middle of making, two power are imported together from middle input assembly and outer ring gear, common output, output torque strengthens, to satisfy all kinds of job requirements.
The utility model adopts single good to its synchronism of pretension of roller to the M shape flat spring of list; Adopt M shape flat spring, anti-Fatigue requires not tight to gearbox with oil. Resistance to wear, adopt roller construction, its working face is whole periphery, and wearing and tearing Evenly, even there are a small amount of wearing and tearing still to keep circular, do not affect serviceability. Anti-high rotating speed, the interior raceway of this structure is round Shape, it is that sliding wear is wiped that interior raceway contacts with roller, when the power shaft High Rotation Speed in raceway need not rotate with roller, in The raceway smooth rotation, it is little to rub, and is difficult for heating.
