Abstract
The utility model discloses a one-way overrunning clutch. The one-way overrunning clutch comprises a shaft and a gear body. Five accommodating grooves are arranged on circumference of an inner ring of the gear body. The accommodating grooves are arc-shaped and are distributed in the inner ring of the gear body. The accommodating grooves and the shaft form a sealed accommodating chamber which is internally provided with a rotary spring and a roller pin. According to the one-way overrunning clutch provided by the utility model, the accommodating grooves are arranged in the inner ring of the gear body, and an energy storage part and the roller pin are installed in the accommodating chamber formed by the accommodating grooves and the shaft, so that the one-way overrunning clutch provided by the utility model is not only simple in structure and convenient to install, but also low in cost and reliable in performance.
Description
Technical field
The utility model relates to a kind of clutch, relates 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.
The model utility content
The purpose of the utility model is to provide a kind of mono-directional overrun clutch, and 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 purpose of the utility model 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.
The beneficial effect of the utility model 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 utility model embodiment 1.
Embodiment
Further specify the technological scheme of the utility model 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 utility model embodiment 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)
1. mono-directional overrun clutch; It is characterized in that: comprise axle and gear body; Offer 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.
