Description

Technical Field

[0001] The present invention relates to the technical field of mechanical grease lubrication, and particularly to an oil receiving groove with a general surrounding shape for a tower mill. Background Art

[0002] In the stirring screw power transmission system of a tower mill, the stirring screw is driven by a vertical motor through a serpentine coupling to drive a vertical speed reducer to rotate. The output shaft of the speed reducer drives the stirring main shaft to rotate through a jaw-type drum coupling, and the stirring main shaft drives the stirring screw to rotate through an end flat key coupling.

[0003] Among them, the stirring main shaft consists of a fixed support seat composed of a single-direction thrust roller bearing and a double-row self-aligning roller bearing in the upper rolling bearing seat. The single-direction thrust roller bearing bears the axial force generated by gravity transmitted by the expansion sleeve, and the double-row self-aligning roller bearing bears the radial force and part of the axial force generated by the rotation of the stirring screw. The lower part of the stirring main shaft consists of a split sliding bearing seat and the internal split sliding bearing, forming a movable support seat. This support seat mainly bears the radial force generated by the rotation of the stirring screw. On the shell of the upper fixed support seat, there are two grease injection ports for dry lubrication of the single-direction thrust bearing and the double-row self-aligning roller bearing. On the shell of the lower split movable support seat, there is a grease injection port for lubricating the split sliding bearing bush.

[0004] As can be seen from the above introduction, in the prior art, the upper fixed rolling bearing seat and the lower movable sliding support seat only have grease injection ports but no oil outlet. During the rotation process, under the action of pressure after lubrication, the waste oil in the grease flows out from their respective upper gaps and accumulates on the upper part of the shell, causing environmental pollution and looking very ugly, which is a problem that must be solved. Summary of the Invention
