Complexity, it is relatively high to the tolerance of part.
Utility model content
Purpose of utility model: in view of the above problems, the object of the present invention is to provide a kind of monoblock type noise reduction idler wheel knots
Structure, to solve the technical problem that cost is relatively high in the prior art, part tolerance is relatively high.
The technical solution adopted in the utility model are as follows:
A kind of monoblock type noise reduction roller structure, which is characterized in that including rotation screw axis, ball, retainer, foreign steamer, with
And noise reduction circle is rolled, one end of the rotation screw axis is cylindrical structure, if being provided in the periphery of the cylindrical structure
Dry ball, several described balls are spaced apart by the retainer, and the ball radial outside is provided with the foreign steamer,
The periphery center of the foreign steamer, which is equipped with, rolls noise reduction circle, and the ball, retainer, foreign steamer and rolling noise reduction circle are with described
Screw axis is rotated as rotary shaft rotation.
Further, the center of the cylindrical structure of one end of the rotation screw axis offers annular mounting groove, several
The lower end of a ball is located in the mounting groove and can be in the mounting groove using the rotation screw axis as rotary shaft
Rotation.
Further, the circumferential direction of the retainer is uniformly provided with several semi-enclosed retaining holes, the retaining hole
The outer diameter of internal diameter and the ball matches, and the ball is installed in the retaining hole.
Further, the ontology that the retaining hole extends the retainer in the axial direction is formed.
Further, the foreign steamer inner circumferential offers first annular slot, and the upper end of several balls is located at institute
It states in first annular slot and can be rotated in the first annular slot by rotary shaft of the rotation screw axis.
Further, the foreign steamer external circumferential offers the second annular groove, and the rolling noise reduction circle is installed on described
In second ring slot and as the foreign steamer rotates synchronously.
The utility model has the advantages that compared with prior art, the utility model has the advantages that due to not using standard in the prior art
Bearing can reduce the cost of drawer roller mechanism, can be convenient installation and replacement, relatively low to the tolerance of part.By
Noise reduction circle is rolled in being equipped with, Noise Reduction can be played the role of, and certain frictional damping can be provided, make drawer roller structure
With stabilization, prolong the service life.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Please refer to Fig. 1 ~ 5, a kind of monoblock type noise reduction roller structure, including rotation screw axis 1, ball 2, retainer 3, foreign steamer
4 and roll noise reduction circle 5, rotation screw axis 1 one end 11 be cylindrical structure, if the periphery in cylindrical structure is provided with
Dry ball 2, several balls 2 are spaced apart by retainer 3, and 2 radial outside of ball is provided with foreign steamer 4, in the periphery of foreign steamer 4
Center, which is equipped with, rolls noise reduction circle 5, and ball 2, retainer 3, foreign steamer 4 and rolling noise reduction circle 5 are to rotate screw axis 1 as rotation
Axis rotation.
Specifically, the center for rotating the cylindrical structure of one end 11 of screw axis 1 offers annular mounting groove 11a, several
The lower end of a ball 2 is located in mounting groove 11a and can rotate screw axis 1 in mounting groove 11a as rotary shaft rotation.
Specifically, the circumferential direction of retainer 3 is uniformly provided with several semi-enclosed retaining holes 31, the internal diameter of retaining hole 31 with
The outer diameter of ball 2 matches, and ball 2 is installed in retaining hole 31.
Specifically, the ontology that retaining hole 31 extends retainer 3 in the axial direction is formed.
Specifically, 4 inner circumferential of foreign steamer offers first annular slot 41, and the upper end of several balls 2 is located at first annular
Screw axis 1 can be rotated in slot 41 and in first annular slot 41 as rotary shaft rotation.
Specifically, 4 external circumferential of foreign steamer offers the second annular groove 42, rolls noise reduction circle 5 and is installed on the second annular groove 42
It is interior and with foreign steamer 4 rotate synchronously.
When specifically used, which is fixed on drawer one by rotating the end of thread of screw axis
Side, drawer plane and foreign steamer 4 cooperate, and pass through drawer plane and roll being in rolling contact for noise reduction circle 5 on foreign steamer 4, thus
Realization pulls drawer, rolls noise reduction circle due to being equipped with, can play Noise Reduction, and can provide certain frictional damping
