Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the special-shaped flange bearing comprises a bush and a flange 1 arranged on the outer wall of the bush, wherein the bush comprises an iron outer sleeve 2 and a copper inner sleeve 3, the outer sleeve 2 and the inner sleeve 3 are mutually attached, a plurality of oil collecting grooves 31 are arranged on the inner wall of the inner sleeve 3, the cross sections of the oil collecting grooves 31 are in an inverted 8 shape, the oil collecting grooves 31 are arranged at intervals, lubricating oil is filled in the oil collecting grooves 31, an oil filling hole 4 is further arranged on the outer wall of the bush, and a sealing plug 40 is clamped in the oil filling hole 4;

an oil discharge groove 32 is further formed in the inner wall of the inner sleeve 3, one end of the oil discharge groove 32 is communicated with the oil collecting groove 31 and is tangent to the outer wall of the oil collecting groove 31, the other end of the oil discharge groove 32 is communicated with the end face of the inner sleeve 3, and a blocking cap is detachably arranged in the oil discharge groove 32. The plug cap has a simple structure and is not shown in the figure; the spindle is inserted in the inner sleeve 3 and firmly fixed, the spindle and the inner sleeve 3 slide relatively, the outer wall of the spindle sweeps through the oil collecting groove 31 discontinuously in the sliding process of the spindle, and as the oil collecting groove 31 is 8-shaped, lubricating oil in the oil collecting groove 31 flows in the oil collecting groove 31, so that the lubricating effect on the spindle is improved; furthermore, the arrangement of the oil discharge groove 32 facilitates the periodic replacement of the lubricating oil in the oil collection groove 31; the oil discharge groove 32 is tangent to the oil collecting groove 31, so that the discharge efficiency is improved.

The elastic body 311 is arranged at the notch of the oil collecting tank 31, the elastic body 311 is in a porous sponge shape, the top of the elastic body 311 is provided with a concave surface attached to the main shaft, the bottom of the elastic body 311 is provided with a plurality of springs 312, and the springs 312 prop the elastic body 311. The elastic body 311 can adsorb lubricating oil, so that the lubricating oil can be more uniformly coated on the outer wall of the main shaft, and the lubrication reliability is ensured; the elastic body 311 can be tightly attached by the pushing action of the spring 312 on the elastic body 311.

The top of the elastic body 311 protrudes outside the oil sump 31, and the bottom of the elastic body 311 is located at the lower part of the oil sump 31. Thus, after the spindle is installed in the inner sleeve 3, the elastic body 311 can generate certain elastic deformation, so that the lubricating oil in the elastic body 311 can be conveniently extruded out, and the lubricating effect on the spindle is ensured to be reliable.
