Abstract

The utility model relates to a clutch, its characterized in that: including being used for the tandem cover to establish at epaxial inner circle, endotheca, be equipped with the outer lane that is used for installing the gear outside the inner circle, the endotheca overcoat be equipped with the holder, the holder extend to between inner circle, the outer lane, be located and be equipped with a plurality of roll groove on the holder between inner circle, the outer lane, the roll inslot be equipped with the rolling member, holder and outer lane friction fit, the inner circle be regular polygon, the rolling member is located between the side and outer lane of inner circle, still is equipped with on the holder to be used for restricting its pivoted limit structure. The present invention uses the technical scheme, the utility model provides a clutch, it can realize the separation and reunion between gear, the axle to make its application range wider.

Description

A kind of clutch

Technical field

The utility model relates to a kind of clutch.

Background technique

We often can use axle, gear is used as transmission, existing gear, axle mounting structure, or gear rotates together with axle, or pinion rotation and axle does not rotate.But in some driving mechanisms, both needed gear, axle rotates together, need again pinion rotation and axle does not rotate, therefore, existing axle, gear installation structure can not be satisfied the demand.

Summary of the invention

The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of clutch, and it can realize the clutch between gear, axle, thus make its using scope wider.

The technical solution of the utility model: a kind of clutch, it is characterized in that: include the inner ring for being one in front and one in back set on axle, inner sleeve, the outer ring for installing gear is provided with outside inner ring, retainer is arranged with outside described inner sleeve, described retainer extends to inner ring, between outer ring, be positioned at inner ring, retainer between outer ring is provided with several rolling grooves, roll piece is provided with in described rolling groove, retainer and outer ring frictional fit, described inner ring is regular polygon, roll piece is between the side and outer ring of inner ring, retainer is also provided with the limit structure rotated for limiting it.

Adopt technique scheme, first geared sleeve is located at outside outer ring and makes gear and outer ring interference fit, again axle is inserted in inner ring, inner sleeve, when needing gear, axle to be separated, by limit structure, retainer is not rotated, now, gear driven outer ring rotating, roll piece dallies in rolling groove, and inner ring, inner sleeve are static; Need gear, be coupling close time, unclamp limit structure, due to retainer and outer ring frictional fit, retainer rotates with outer ring, thus drives roll piece motion, roll piece drives inner ring to rotate, and then be with moving axis, inner sleeve to rotate, and therefore, the clutch of this structure, it can realize the clutch between gear, axle, thus makes its using scope wider.

Further setting of the present utility model: described limit structure is be arranged on the spacing bayonet socket on the retainer that is positioned at outside inner sleeve.

Adopt above-mentioned further setting, only need to be snapped in spacing bayonet socket by position-limited lever to limit retainer rotation, more convenient to operate.

Of the present utility modelly to arrange further again: described inner ring is regular hexagon, and described roll piece is provided with six and lays respectively at six of inner ring between side and outer ring.

Adopt and above-mentionedly to arrange further again, make the service behaviour of clutch more stable.

Further setting more of the present utility model: described roll piece is cylindric.

Adopt and above-mentionedly further to arrange again, roll piece is promoted when inner ring rotates more smooth and easy, service behaviour is more stable.

Embodiment

As Figure 1-3, a kind of clutch, include the inner ring 1 for being one in front and one in back set on axle, inner sleeve 2, the outer ring 3 for installing gear is provided with outside inner ring 1, retainer 4 is arranged with outside described inner sleeve 2, described retainer 4 extends to inner ring 1, between outer ring 3, be positioned at inner ring 1, retainer 41 between outer ring 3 is provided with several rolling grooves 411, rolling groove 411 is uniformly distributed around the axis of retainer 4, columned roll piece 5 is equipped with in described rolling groove 411, be positioned at inner ring 1, retainer 41 between outer ring 3 and outer ring 3 inwall frictional fit, described inner ring 1 is regular polygon, roll piece 5 is between the side and outer ring 3 of inner ring 1, be positioned at the spacing bayonet socket 421 retainer 42 outside inner sleeve 2 being also provided with and rotating for limiting it, in the utility model specific embodiment, inner ring 1 is regular hexagon, rolling groove 41, roll piece 5 correspondence is provided with six.

During use, first geared sleeve is located at outer ring 3 outer and make gear and outer ring 3 interference fit, again axle is inserted in inner ring 1, inner sleeve 2, when needs gear, axle are separated, are snapped in spacing bayonet socket 421 by outside position-limited lever and retainer 4 is not rotated, now, gear driven outer ring 3 is rotated, roll piece 5 dallies in rolling groove 41, and inner ring 1, inner sleeve 2 are static, and axle also remains static; When needs gear, be coupling close time, position-limited lever is skidded off spacing bayonet socket 421, due to retainer 4 and outer ring 3 inwall frictional fit, retainer 4 rotates with outer ring 3, thus drives roll piece 5 to rotate, roll piece 5 promotes inner ring 1 and rotates, and then band moving axis, inner sleeve 2 are rotated, therefore, the clutch of this structure, it can realize the clutch between gear, axle, thus makes its using scope wider.
