Supercharger with function of preventing fine scrap iron from entering

Abstract

The invention discloses a supercharger with the function of preventing fine scrap iron from entering. The supercharger comprises a supercharger main body and an intermediate body, and the intermediatebody is fixed to the middle part of the supercharger; an oil inlet is formed in the middle part of the intermediate body, and the oil inlet penetrates through the intermediate body, and communicateswith a lubricating oil passage on the supercharger main body; and the inner wall of the oil inlet is magnetically connected with a strong magnetic ring. According to the supercharger with the functionof preventing fine scrap iron from entering, through arrangement of the strong magnetic ring in the improved oil inlet, scrap iron doped in oil is adsorbed through the strong magnetic ring; not onlycan the scrap iron doped in lubricating oil be filtered out and prevented from entering the lubricating oil passage, but also the influence on the lubricating oil entering the oil inlet is not affected; and the oil feeding smoothness is guaranteed. The supercharger is simple in structure, convenient in installation, obvious in effect and easy maintenance and cleaning, the situation that the scrapiron enters the lubricating oil passage and consequently a floating bearing is damaged is effectively avoided, and troubles and losses caused by damage of the supercharger are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of superchargers, in particular to a supercharger capable of preventing the entry of fine iron filings. Background technique [0002] Existing superchargers often need to be repaired or replaced due to damage to the floating bearing. Most of the damage is caused by foreign matter entering the supercharger, which causes damage to the floating bearing. Foreign matter entering the supercharger is mostly caused by improper maintenance of the engine oil filter. Or improper operation during the maintenance and replacement of the supercharger, resulting in long-term wear and loss of iron chips mixed into the lubricating oil. The small size of the iron chips can easily enter the oil hole with the lubricating oil and enter the lubricating oil channel of the floating bearing. Due to the small internal clearance of the lubricating oil channel of the floating shaft, it is very easy to cause damage to the floating bearin...
