Abstract
The utility model belongs to the technical field of unidirectional overrunning clutches, which is a universal component in machines, and the utility model comprises an outer sleeve, an inner core, cams, action springs and support rollers. The utility model is characterized in that the inner core, the cam, the action spring and the support roller are respectively sheathed in the outer sleeve, wherein the cam and the support rollers are respectively contacted with the outer ring of the inner core and the inner ring of the outer sleeve. The cams are mutually connected with the action springs, the support roller are separately arranged among the cams and the action springs are arranged in the flutes between the cams and the support rollers. The utility model not only has the advantages of simple structure, easy processing and low cost, but also has the function of bearing centering, the utility model has the advantages of rapid disembodiment, low noise and long service life when used, and the utility model can be widely used on automobiles, motorcycles and other machinery devices.
Description
Technical field the utility model belongs to and has mono-directional overrun clutch class technical field, is the spare part in common use in a kind of machinery.
The existing cam type overpass clutch of background technique is to do the motion realization transcendent function that deflects on the inner core cylindrical that matches with it or on the inner ring of overcoat by cam, it has a direction combination, the function that another direction breaks away from, therefore being widely used in every field such as vehicle, machinery, instrument, is a kind of general basic component.
Because between cam and the Internal and external cycle that combines arranged a working clearance, therefore, free wheel device does not possess the centering function of bearing, it can not use as bearing separately.Generally speaking, in order in mechanical structure, to address this problem, two kinds of methods are arranged, the one, one or both sides are installed one or two bearing more simultaneously on the mechanical axis that mono-directional overrun clutch is installed, like this, the effect that bearing plays centering and supports, mono-directional overrun clutch then mainly plays the mono-directional overrun clutch.Another kind method is that promptly mono-directional overrun clutch is in the center, has been equipped with two bearings simultaneously in both sides, forms one, is directly installed on the mechanical axis in use with direct the being made of one structure of mono-directional overrun clutch and bearing.This part is called the bearing with overdrive clutch function.
Though more than two kinds of structures solved the centering problem of mono-directional overrun clutch, all exist complex structure, volume is bigger, the more high deficiency of cost.
The summary of the invention the purpose of this utility model provides a kind of cam type overpass clutch that roller supports that contains, and it is simple in structure, easy to process, cost is low, and also has the function of bearing centering, and disengaging is fast during use, noise is little, the life-span is long.
The cam type overpass clutch that contains the roller support described in the utility model, comprise overcoat, inner core, cam, start spring and supporting roller, it is characterized in that: inner core, cam, start spring and supporting roller are contained in the overcoat respectively, cam is between inner core and overcoat, and contact with the cylindrical of inner core and the inner ring of overcoat, middle part at the cam cylindrical is provided with groove, is connected with the start spring between cam and the cam; Supporting roller is provided with groove at the middle part of supporting roller cylindrical between inner core and overcoat, supporting roller is contained between cam and the cam at interval, and contacts with the cylindrical of inner core and the inner ring of overcoat; The start spring is contained in the groove at cam and supporting roller cylindrical middle part.
The described cam type overpass clutch that contains the roller support, it is characterized in that: supporting roller and cam can be intercross arrangement, can not be intercross arrangement with cam also.
Describedly contain the cam type overpass clutch that roller supports, it is characterized in that: the quantitative proportion of supporting roller and cam can from 0 to 9, perhaps bigger.
Describedly contain the cam type overpass clutch that roller supports, it is characterized in that: the diameter of supporting roller can be bigger than the diameter of cam, also can be smaller than the diameter of cam, also can with the equal diameters of cam.
The described cam type overpass clutch that contains the roller support, it is characterized in that: the supporting roller that is contained between the cam can be that roller also can be a spin.
The utility model is not only simple in structure, easy to process, cost is low, and also has the function of bearing centering, and disengaging is fast during use, noise is little, the life-span is long.Can be widely used on automobile, motorcycle and other machinery.

Embodiment
Fig. 1 is the specific embodiment that the utility model is used for motorcycle, overcoat 1 is a driving gear, the inner core 2 that cooperates with overcoat 1 inner ring is driven member, be contained on the output shaft of gearbox, between the inner ring of the cylindrical of inner core 2 and overcoat 1, be provided with three uniform supporting rollers 5 and 21 cams 3 and a start spring 4, supporting roller 5 and cam 3 are intercross arrangement, when overcoat 1 clockwise rotates and rotating speed when being higher than inner core 2, the right that cam 3 promptly is partial to inner core 2 is stuck between the inner ring of the cylindrical of inner core 2 and overcoat 1, and inner core 2 promptly rotates synchronously with overcoat 1; When motorcycle is in idling or flameout state, or the rotating speed of inner core 2 is during greater than the rotating speed of overcoat 1, and inner core 2 promptly surmounts overcoat 1 and rotates; Thereby reduced machine members, prolonged working life, and can save fuel oil.
