Technical Field

The utility model relates to the technical field of chain wheels, in particular to a chain wheel bearing set structure.

Background

At present, a user needs to purchase a gear ring and a bearing to assemble to form the chain wheel respectively on the market, and the user can assemble the chain wheel formed by self, so that the eccentric condition exists between the gear ring and the bearing, and better coaxiality cannot be ensured.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a chain wheel bearing set structure which can effectively solve the problems of the background technology.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a sprocket bearing group structure, includes a structure main part, the structure main part includes sprocket body, eccentric shaft sleeve and bearing, sprocket body and the coaxial setting of bearing, just sprocket body and bearing outer lane fixed connection, eccentric shaft sleeve and bearing inner circle fixed connection, eccentric shaft sleeve coaxial arrangement has movable groove and fixed slot, movable groove swing joint has eccentric block.

Preferably, the sprocket body evenly is provided with a plurality of heat dissipation holes around the middle shaft.

Preferably, the fixed slot is arranged in the movable slot, both the movable slot and the fixed slot are sunken towards the axis of the eccentric shaft sleeve, and the radius of the fixed slot is smaller than that of the movable slot.

Preferably, the eccentric block is in threaded connection with a fixing bolt, the fixing bolt extends from the outer edge of the eccentric shaft sleeve to the axis of the eccentric shaft sleeve, and the fixing bolt is matched with the fixing groove to fix the position of the eccentric block.

Preferably, the eccentric shaft sleeve is sleeved with an annular fixing sleeve, the fixing sleeve is provided with a lug matched and abutted with the surface of the eccentric block, and the fixing bolt penetrates through the lug to be in threaded connection with the eccentric block.

Compared with the prior art, the utility model has the beneficial effects that:

simple structure, convenient to use, and can realize movable adjustment eccentric block and offset eccentric force, reduce the production precision and the manufacturing cost of bearing and sprocket body, have better regulation effect, offset eccentric force through sliding adjustment eccentric block in movable groove during the use, with fixing bolt bottom tightly with fixed slot butt fixed after confirming the eccentric block position, can also add the adhesive when fixed and improve fixed effect, set up the picture simultaneously and can realize movable groove, fixed inslot is not polluted, specific in movable groove, fixed inslot adds the adhesive before unscrewing fixing bolt and take out the fixed cover, embolia the eccentric shaft cover with the fixed cover after the celestial adhesive in, the rethread fixing bolt is fixed.
