Abstract
The utility model discloses a bidirectional overrunning clutch, which is composed by an outer casing, an inner casing, a sealing plate, and rollers. The inner casing is in a planetary wheel shape, the two conjunction surfaces of the inner casing are provided with rollers, one side of rollers is provided with a compression spring, a clutch pawl is arranged between two rollers. The outer casing is in an aperture shape, which is sleeved outside the inner casing and the rollers, the clutch pawl is fixed on the sealing plate. The utility model has the advantages of simple and compact structure, reliable movement, small size, which is especially suitable for the limitation protection and the positioning of electrical equipment and mechanical device.
Description
Technical field:
The utility model relates to a kind of roller double rolling key clutch.
Background technique:
On some electric equipment and mechanical device; in order to realize duplicate protection and other special purpose between machinery and the electrical equipment; usually need to use clutch to finish predetermined actions; existing machine two-way free wheel device volume is bigger; complex structure; make difficulty, processing cost is higher, has therefore limited further applying of double rolling key clutch.
Summary of the invention:
Goal of the invention of the present utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple in structure, and volume is less, is easy to the double rolling key clutch of manufacturing.
The shrouding (6) of the utility model overcoat (3), interior cover (5), overcoat (3) end face and roller (1) are formed, interior cover (5) is the star-wheel shape, roller (1) is equipped with at interior cover (5) two wedging face places, one side of roller (1) is equipped with pressure spring (4), be provided with the shift fork of clutch pallet (2) in the middle of two rollers (1), overcoat (3) is the aperture shape, is sleeved on the outside of interior cover (5) and roller (1), and clutch pallet (2) is fixed on the shrouding (6).
Parts are few, simple in structure in addition for the utility model, reliable in action, and volume is less.Be specially adapted to the position limitation protection and the location of electrical equipment and mechanical device.

Accompanying drawing 1 is the utility model example structure schematic representation.
Accompanying drawing 2 is the generalized section of Fig. 1.
Accompanying drawing 3 is the rear view of Fig. 1.
Accompanying drawing 4 is another example structure schematic representation of the utility model.
Accompanying drawing 5 is Fig. 1 circled partial enlarged drawing.
Accompanying drawing 6 is Fig. 4 circled partial enlarged drawing.
Embodiment:
Referring to accompanying drawing 1, the overcoat of present embodiment (3) is the aperture shape, is sleeved on the outside of interior cover (5), with interior cover (5) movingly.Interior cover (5) is made the star-wheel shape, two wedging faces of interior cover (5) are equipped with roller (1), respectively establish one about roller (1), one side of roller (1) is equipped with pressure spring (4) respectively, to withstand roller (1), make it be easy to wedging when proper functioning, clutch pallet (2) is fixed on two side shroudings (6).Clutch pallet (2) can be made one or more external pallets according to actual needs, and all the other can be made into rivet (8) and form.Between overcoat (3) and the interior cover (5) seal ring (7) is arranged.
Overcoat of the present utility model (3) is as making the light cylindrical enclosure, and interior cover (5) is made star-wheel shape tooth cover, and then overcoat (3) is a driving wheel, and interior cover (5) is driven wheel (referring to an accompanying drawing 1).Interior cover is as making the light cylinder axis, and overcoat (3) is made star-wheel shape tooth cover, and as shown in Figure 4, then interior cover (5) is a driving wheel, and overcoat (3) is a driven wheel.The conversion of active and passive case is very easy.
Clutch pallet of the present utility model (2) is when moving to assigned position, blocked by external mandril, clutch pallet (2) promotes roller (1) and pressing spring (4), make roller (1) remove cover (5) and overcoat (3) in the wedging, inside and outside cover separately, initiatively cover can continue by former direction rotation, and passive cover then stops operating, and promptly plays free wheel device.As initiatively cover rotation in the opposite direction, then another group clutch pallet (2) overlaps in wedging under the state of (5) and overcoat (3) again, then can continue transferring power under clutch state.
Claims (1)
1, a kind of by the shrouding (6) of overcoat (3), interior cover (5), overcoat (3) end face and the double rolling key clutch that roller (1) is formed, it is characterized by interior cover (5) is the star-wheel shape, roller (1) is equipped with at interior cover (5) two wedging face places, one side of roller (1) is equipped with pressure spring (4), be provided with clutch pallet (2) in the middle of two rollers (1), overcoat (3) is the aperture shape, is sleeved on the outside of interior cover (5) and roller (1), and clutch pallet (2) is fixed on the shrouding (6).
