Oil and gas lubricating spacer bush assembly

Abstract

The invention discloses an oil and gas lubricating spacer bush assembly. The oil and gas lubricating spacer bush assembly comprises an outer spacer bush, an oil guiding sleeve, an oil guiding passageway, an oil and gas collecting ring groove, an oil returning ring groove, an oil inflow ring groove and a sealing ring; the oil guiding sleeve is inserted and connected in the outer spacer bush; the oil and gas collecting ring groove is located on the top of the outer spacer bush, is arranged in the circumference direction of the outer spacer bush, is used for being communicated with an upper bearing track, and is communicated with the oil returning ring groove; the oil inflow ring groove is communicated with the oil guiding passageway which is located on the side, close to a lower bearing inner ring, of the oil guiding sleeve; the exterior of the outer spacer bush is sleeved with the sealing ring; and in use, the sealing ring is located between a bearing pedestal and the outer spacer bush to be used for sealing. The oil and gas lubricating spacer bush assembly can effectively reduce the phenomenon that heat generation of a bearing is too high, and can avoid the phenomena that oil spraying is not uniform and the lubricating and cooling effect is poor.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to an oil-air lubrication spacer assembly. Background technique [0002] At present, with the advent of the era of full automation, automated processing parts will inevitably cover a wider field, and diversified high-hardness and high-strength materials will gradually be applied to the field of engraving, milling and grinding. Therefore, the high-precision electric spindle will inevitably occupy an important position in the field of machine tool processing. [0003] The electric spindle includes a bearing seat, a bearing and a shaft core. The bearing is arranged inside the bearing seat. The bearing is mainly composed of an outer ring, an inner ring, and a rolling body. The rolling body rolls in the bearing raceway, and the shaft core pivotally fits with the bearing seat through the bearing. The lubrication of bearings is generally divided into grease lubrication and oil-air lubri...
