A kind of idler wheel anti-loose structure of reason avoids the opposite sliding of idler wheel and inner sleeve, reduces mutual abrasion, ensure the normal fortune of equipment
Row, while also ensuring the service life of idler wheel and inner sleeve, reduce economic cost.
To achieve the above object, the technical solution adopted in the utility model is：A kind of idler wheel anti-loose structure, including idler wheel,
Locked inner sleeve and clamping inner sleeve, the inner ring of the idler wheel are matched with the outer ring of locked inner sleeve；The locked inner sleeve, with rolling
The inner ring of wheel and the outer ring of clamping inner sleeve match；The inner ring of the clamping inner sleeve is connected with axis, outer ring with it is locked in
The inner ring of set matches.
In the present invention：The idler wheel is equipped with counterface, and the counterface is equipped with shrinkage pool.
In the present invention：At least provided with two symmetrical shrinkage pools on the counterface.
In the present invention：The outer ring of the locked inner sleeve is equipped with boss, and the boss mutually agrees with shrinkage pool,
To realize the locked of idler wheel and locked inner sleeve.
In the present invention：The boss is at least 2, is symmetrically distributed in the outer ring of boss.
In the present invention：The inner ring of the locked inner sleeve is equipped with strip boss and dot protrusion.
In the present invention：The dot protrusion is 2, and is symmetrically distributed in the inner ring of locked inner sleeve.
In the present invention：The inner clamping sleeve top is equipped with strip trepanning and two dot trepannings, the item
Shape trepanning is matched with strip boss, and the dot trepanning is matched with dot protrusion, to realize the fixation of two inner sleeves
In conjunction with.
In the present invention：Idler wheel, locked inner sleeve and the clamping inner sleeve is formed by plastic production.
With the above structure, the utility model has the beneficial effect that：The utility model simple structure and reasonable design uses
It is convenient, the original interference fit of transmission device is become being fixedly connected, the abrasion of idler wheel and inner sleeve is effectively reduced, improves
The service life of transmission device reduces the economic cost of equipment；In addition, above structure can also ensure the rotation speed of idler wheel well
Degree.

【Specific implementation mode】
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but be not intended to limit the scope of the present invention.
As shown in Figs. 1-2, a kind of idler wheel anti-loose structure, including idler wheel 1, locked inner sleeve 2 and clamping inner sleeve 3, the rolling
Wheel 1, locked inner sleeve 2 and clamping inner sleeve 3 are formed by plastic production；The inner ring of the idler wheel 1 and the outer ring phase of locked inner sleeve 2
Cooperation；The locked inner sleeve 2, matches with the outer ring of the inner ring of idler wheel 1 and clamping inner sleeve 3；The clamping inner sleeve 3 it is interior
Circle is connected with axis, and outer ring is matched with the inner ring of locked inner sleeve 2.The idler wheel 1 is equipped with counterface, the cooperation
