Further, a first shaft hole for the steel sleeve to be clamped in is formed in the shaft center of the guide wheel.

Further, the steel sleeve is pressed into the first shaft hole through stamping.

Further, a second shaft hole for clamping the bearing is formed in the axis of the steel sleeve.

Further, a clamping groove for clamping the retainer ring is formed in the inner wall of the second shaft hole.

Further, the bearing is a deep groove ball bearing.

Further, the steel sleeve is made of 45 steel materials.

Further, the guide wheel and the side wall of the steel sleeve are provided with a nozzle tip.

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

according to the high-strength guide wheel structure, the steel sleeve is clamped in the guide wheel, the bearing is clamped in the steel sleeve, the retainer rings are clamped at the two ends of the bearing in the steel sleeve, the strength of the inner wall of the guide wheel is improved, the abrasion between the rotating shaft and the inner wall of the guide wheel is reduced, and the service life is prolonged.

And (II) after the steel sleeve is pressed into the first shaft hole, the guide wheel and the side wall of the steel sleeve are provided with oil nozzles for lubricating each relative moving part, so that the abrasion is further reduced, and the service life is prolonged.
