Abstract
The present invention belongs to the field of unidirectional free-wheeling clutch technology, and relates to a universal mechanical component-roller free-wheeling clutch containing roller support. It includes the following several portions: outer sleeve, inner core matched with inner ring of outer sleeve, left gland and right gland connected with two sides of outer sleeve and two sides of inner core, free-wheeling roller and supporting roller. Said invention also provides their connection mode, and provides the working principle of said free-wheeling clutch.
Description
Technical field the invention belongs to has mono-directional overrun clutch class technical field, is the spare part in common use in a kind of machinery.
The existing roller-type overrunning clutch of background technique is to realize transcendent function by the motion of roller on the inclined-plane, impartial inclined-plane is made in its inner ring or outer ring, when roller moves on this inclined-plane, 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 roller 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.
Summary of the invention the purpose of this invention is to provide a kind of roller-type overrunning 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 roller-type overrunning clutch that contains the roller support of the present invention, comprise overcoat, the inner core that cooperates with the overcoat inner ring, the left gland that is connected overcoat both sides or inner core both sides and right gland and surmount roller and supporting roller, it is characterized in that on the cylindrical of inner core, being provided with installing and surmount surmounting the inclined-plane and the arc surface of supporting roller being installed of roller, in each surmounts inclined-plane and arc surface, be provided with one and surmount roller and supporting roller, and contact with the inner ring of overcoat; Perhaps on the inner ring of overcoat, be provided with the arc surface that surmounts inclined-plane and installation supporting roller that surmounts roller is installed, in each surmounts inclined-plane and arc surface, be provided with one and surmount roller and supporting roller, and contact with the cylindrical of inner core.
The described roller-type overrunning clutch that contains the roller support, it is characterized in that on the cylindrical of inner core, being provided with installing and surmount surmounting the inclined-plane and the arc surface of supporting roller being installed of roller, these two kinds surmount the inclined-plane and arc surface can be an intercross arrangement, can not be intercross arrangement also; Surmount the quantitative proportion of inclined-plane and arc surface can from 0 to 9, perhaps bigger.
The described roller-type overrunning clutch that contains the roller support, it is characterized in that on the inner ring of overcoat, being provided with installing and surmount surmounting the inclined-plane and the arc surface of supporting roller being installed of roller, these two kinds surmount the inclined-plane and arc surface can be an intercross arrangement, can not be intercross arrangement also; Surmount the quantitative proportion of inclined-plane and arc surface can from 0 to 9, perhaps bigger.
Describedly contain the roller-type overrunning clutch that roller supports, it is characterized in that the diameter of supporting roller at it can be bigger than the diameter that surmounts roller, also can be smaller than the diameter that surmounts roller, also can with the equal diameters that surmounts roller.
The described roller-type overrunning clutch that contains the roller support is characterized in that the roller that surmounts that surmounts in the inclined-plane being contained in of it can be that roller also can be a spin with the supporting roller that is contained in arc surface.
Overcoat of the present invention not only can be driven member but also can be driving link, and inner core not only can be driving link but also can be driven member, decides according to different use condition.The present invention 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.
