Abstract
The invention discloses a one-way overrunning clutch, which comprises a shaft and a gear body, wherein five accommodation grooves are arranged at the circumference of an inner ring of the gear body, are in a circular arc shape and are uniformly distributed on the inner ring of the gear body, in addition, the accommodation grooves and a shaft form a sealed accommodation cavity, and a spiral spring and a rolling needle are arranged in the accommodation cavity. The one-way overrunning clutch has the advantages that the accommodation grooves are arranged in the inner ring of the gear body, energy storage components and the rolling needle are arranged in the accommodation cavity formed by the accommodation grooves and the shaft, the structure is simple, the installation is convenient, in addition, the cost is low, and the performance is reliable.
Description
Technical field
The present invention relates to a kind of clutch, relate in particular to a kind of mono-directional overrun clutch.
Background technique
At present, general overrunning clutch by the outer ring, with the inner ring of outer ring concentric arrangement, be installed in a plurality of rollers that are used for transmitting torque between outer ring and the inner ring, the retainer that keeps roller and the spring component of the direction pair roller application of force that the edge engages with the camming surface of outer ring or inner ring and form.This structure exists complex structure, installation is loaded down with trivial details and manufacture cost is high shortcoming.
Summary of the invention
The object of the present invention is to provide a kind of mono-directional overrun clutch, it has characteristics simple in structure, that installation is convenient, cost is low, has effectively solved the problem that mono-directional overrun clutch exists in the existing technology.
The objective of the invention is to realize through following technological scheme:
A kind of mono-directional overrun clutch, it comprises axle and gear body, offers the containing groove of a plurality of circular arcs on the inner ring circumference of said gear body, said containing groove forms the holding cavity that seals with axle, and energy storage component and needle roller are installed in the said holding cavity.
Especially, said energy storage component is a helical spring.
Especially, said containing groove is distributed on the inner ring of gear body.
Especially, the number that is provided with of said containing groove is five.
Beneficial effect of the present invention does, said mono-directional overrun clutch is compared with prior art offered containing groove in the inner ring of gear body, and energy storage component and needle roller are installed in the holding cavity that containing groove and axle form, and is not only simple in structure, be convenient to install; And cost is low, reliable performance.
Description of drawings
Fig. 1 is the structural representation of the mono-directional overrun clutch that provides of the specific embodiment of the invention 1.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the mono-directional overrun clutch that provides of the specific embodiment of the invention 1.
In the present embodiment; A kind of mono-directional overrun clutch comprises axle 1 and gear body 2; Offer five containing grooves 3 on the inner ring circumference of said gear body 2; Said containing groove 3 is circular arc and is distributed on the inner ring of gear body 2, and said containing groove 3 forms a holding cavity that seals with axle 1, interior helical spring 5 and the needle roller 4 installed of said holding cavity.
During work, axle 1 is when forward rotating, and the needle roller 4 in its driven gear body 2 rotates; And the rotating force that is produced during this moment needle roller 4 rotation is pressed to helical spring 5 directions; This rotating force forces needle roller 4 to move to helical spring 5 directions, makes between gear body 2 endoporus and the needle roller 4 to have the gap, forms a kind of being slidingly matched between them thereby lead to cause; Cause axle 1 in the endoporus of gear body 2, to be free to slide rotation, and gear body 2 does not rotate.
When gear body 2 was rotated counterclockwise, the needle roller 4 of interior dress, forced needle roller 4 to drive axle 1 rotation together, thereby reaches the spring energy-storage purpose equally circular shape zone special in needle roller 4 pressed toward gear bodies 2 endoporus owing to receive the effect of helical spring 5 elastic force.
Claims (4)
