Multi-layer split type assembly structure of main shaft of ball lapping machine

Abstract

The invention discloses a multi-layer split type assembly structure of a main shaft of a ball lapping machine. The multi-layer split type assembly structure comprises a stepped main shaft, the middleof the stepped main shaft is installed in a main shaft box body through an oil separation pipe, a rear end of the oil separation pipe and the stepped main shaft are rotationally installed through a first bearing, a front end of the oil separation pipe is sleeved with a double-end flange, the double-end flange is arranged in the main shaft box body, and the double-end flange and the main shaft boxbody are rotationally installed and assembled through a second bearing and a third bearing; a spline sleeve is installed at an end of a driving end of the stepped main shaft, the inner side of the spline sleeve is sleeved with an unloading flange, and the unloading flange is fixedly connected with the main shaft box body; a main shaft belt pulley is rotationally mounted on the unloading flange through a fourth bearing, a rear end of the main shaft belt pulley is fixedly connected with the spline sleeve, and a rotating plate tire matched with the double-end flange is fixedly mounted on the double-end flange. By adopting a split type assembly structure, a lining is not needed for sealing, and the phenomena of oil leakage and oil seepage due to the fact that the sealing performance through the rotation of the main shaft are avoided.

Description

Technical field: [0001] The invention relates to the field of ball grinding machine equipment, and mainly relates to a multi-layer split assembly structure of a ball grinding machine main shaft. Background technique: [0002] The existing structure of the main shaft of the ball grinder is based on the structure of lubricating oil, lubricating bearings, and bushing oil seals, so that there is no oil leakage and oil leakage. However, due to the continuity and durability of its work, the oil seal will There is wear between the bushing and the bushing, so there is a gap and oil leakage, resulting in bearing necrosis, the main shaft cannot work normally and the machine is shut down, and normal production cannot be performed. It needs to be shut down frequently for replacement and maintenance, resulting in high production and processing costs and affecting normal processing. Work efficiency is low. Invention content: [0003] The purpose of the present invention is to make up f...
