Abstract
A roller-type overrunning clutch with a roller supports consists of a housing washer, a core with a transcendental bevel and a cambered surface, a overrunning and supporting rollers. In the housing washer are mounted the core and overrunning and supporting rollers. The overrunning rollers are located in the transcendental bevel on the core and in the inner wall of the housing washer. The supporting rollers are located in the cambered surface on the core and are in contact with the inner wall of the housing washer.
Description
Technical field the invention belongs to has the mono-directional overrun clutch class, 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 arc inclined-plane, garden 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 is in order to overcome the above problems, and the present invention has designed a kind of roller-type overrunning clutch that roller supports that contains, it is characterized in that it by outer ring, band surmount inclined-plane and arc surface inner core, surmount roller and several parts of supporting roller are formed.
This internal surface that contains the outer ring of the roller-type overrunning clutch that roller supports is a smooth annulus, its outer surface matches with the mechanical hole that needs to install, internal surface be with clutch surmount roller and supporting roller matches, it can be made by bearing steel, and obtains high hardness through Overheating Treatment.
Its inner core also is an annulus, endoporus matches with other mechanical axis, and outer round surface surmounts the inclined-plane of roller by installation and the arc surface of installation supporting roller is formed, these two kinds surmount the inclined-plane and arc surface is an intercross arrangement, the effect that surmounts the inclined-plane is the effect of playing roller one-way clutch in the common free wheel device, and the roller of being installed on the arc surface can play the effect of centering, has the function of bearing.Arc surface and surmounting the quantitative proportion from 0 to 5 on inclined-plane, when arc surface was 0 with the quantitative proportion that surmounts the inclined-plane, promptly free wheel device did not have arc surface, when only surmounting the inclined-plane, is exactly a kind of common roller-type overrunning clutch.Arc surface is big more with the quantitative proportion that surmounts the inclined-plane, and the effect of its bearing centering is also big more, in practice, can determine its proportional numbers according to the stressing conditions of free wheel device and the centering precision of requirement.
The diameter of its supporting roller 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.
It surmount roller and supporting roller can be a roller, also can be spin.
Because this roller-type overrunning clutch that contains the roller support has the dual functions of common free wheel device and bearing, the composite structure of forming by bearing and free wheel device that can the alternative structure complexity, also have series of advantages such as volume is little, in light weight, cost is low simultaneously, therefore, the roller-type overrunning clutch that contains the roller support of this structure has tangible practical effect.
Description of drawings Fig. 1 is this structural representation that contains the roller-type overrunning clutch of roller support, and Fig. 2 is this roller-type overrunning clutch inner core schematic representation that roller supports that contains.Wherein sequence number 1 is this outer ring that contains the roller-type overrunning clutch of roller support among Fig. 1, sequence number 2 is inner cores, and sequence number 3 is to surmount roller, and sequence number 4 is supporting rollers, sequence number 5 is that the circular arc inclined-plane of supporting roller is installed, and sequence number 6 is that the inclined-plane that surmounts that surmounts roller is installed.
Embodiment of embodiment is described below in conjunction with Fig. 1 and Fig. 2, contain the roller-type overrunning clutch that roller supports, by outer ring, band surmount inclined-plane and arc surface inner core, surmount roller and supporting roller is formed, inner core 2 is housed in outer ring 1, surmounts roller 3 and supporting roller 4, surmount roller 3 and be positioned at installation on the inner core 2 and surmount surmounting inclined-plane 6 and placing the inwall of outer ring 1 of roller, supporting roller 4 is positioned at the circular arc inclined-plane 5 of the installation supporting roller on the inner core 2 and contacts with outer ring 1 inwall.
Claims (4)
1. contain the roller-type overrunning clutch that roller supports, it is characterized in that it by outer ring, band surmount inclined-plane and arc surface inner core, surmount roller and supporting roller is formed.
2. the roller-type overrunning clutch that contains the roller support according to claim 1, the inner core outer round surface that it is characterized in that it is made up of the arc surface that surmounts inclined-plane and installation supporting roller that installation surmounts roller, these two kinds surmount the inclined-plane and arc surface is an intercross arrangement, arc surface and surmount the quantitative proportion on inclined-plane can from 0 to 5.
3. the roller-type overrunning clutch that contains the roller support according to claim 1, the diameter that it is characterized in that its supporting roller 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.
4. according to claim 1ly contain the roller-type overrunning clutch that roller supports, it is characterized in that it surmount roller and supporting roller can be that roller also can be a spin.
